There are three cases for the ear amplifier. First, the audio source used, for example, there is no earphone dedicated output jack on the CD/DVD player. At this time, a headphone amplifier can be equipped, and the audio output from the CD/DVD player (LINE OUT) is connected to the audio of the amplifier by two signal lines. Just enter the jack. In the second case, a low-sensitivity, high-impedance earphone, if you can't push it with an existing audio source such as a Walkman, you should also purchase a headphone amplifier. The third case is a medium-to-high-end earphone. The introduction of such an earphone with the existing headphone jack can not exert the potential of the earphone. Adding a headphone amplifier can further improve the sound quality. In this case, we should consider adding A high quality headphone amplifier. How to choose the tube headphone power amplifier transistor headphone amplifier? At present, the tube head power amplifier on the market uses the cathode level output device as the final stage power amplifier. This type of circuit structure should be said to be very reasonable. Therefore, it is adopted by most manufacturers. However, this circuit has a high output impedance and can only be used with headphones of 200 or more ohms, and the higher the impedance, the smaller the distortion. The final stage of the power amplifier of the transistor earphone adopts an OTL circuit, and the impedance requirement is not strict, and the lower the impedance, the larger the output current and the greater the power. Therefore, the transistor power amplifier is high, medium and low impedance, but it is better to push the medium and low impedance headphones.
[Headphone manufacturer] What are the meanings of some related parameters and sound quality terms? First, the headset related parameters: Impedance: Pay attention to the difference between the sense and the resistance. In the world of direct current (DC), the effect of an object on current obstruction is called resistance, but in the field of alternating current (AC), in addition to the resistance that blocks the current, the capacitance and inductance It also obstructs the activity of the current. This effect is called reactance, and the impedance we call everyday is the sum of the resistance and the reactance in the vector. Sensitivity: The sound pressure level that can be announced by the earphone when the input power of 1 mW is input to the earphone (the unit of sound pressure is decibel, the louder the sound pressure is, the higher the volume), so the higher the sensitivity, the smaller the impedance, the earphone The simpler the sound, the simpler the drive. Frequency Response: The sensitivity value corresponding to the frequency is the frequency response. The image is the frequency response curve. The plan that human hearing can reach is about 20Hz-20000Hz. Now the old earphone technology has arrived. Kind of requirements. Second, the sound quality comment terminology: the instrument or vocal can reach the highest tone and the lowest sound between the planning sound: also known as the sound, one of the characteristics of the static and dynamic, such as erhu, pipa is different sounds: natural music The opposite of neutrality, that is, the static and negative stains of some features that the program itself does not have, such as the kind of motion that is spoken in a jar is a typical sound. The sounding indicates that there are more (perhaps reduced) components in the reproduced signal, which is obviously a distortion. Distortion: The output of the device cannot fully reproduce its input, and the distortion of the waveform or the increase or decrease of the signal component may occur. Dynamic: Allows to record the ratio of the maximum information to the minimum information. Transient response: The device's ability to follow the burst signal in music. A device that responds well to a transient should respond to the signal as soon as it is received, and the signal will stop when it stops, and it will never catch the vine. (Typical instrument: piano) Signal-to-noise ratio: Also known as the signal-to-noise ratio, the useful component of the signal is compared with the strength of the noise, often marked with the number of decibels. The higher the signal-to-noise ratio of the device, the less noise it has. Air Sense: An open term used to indicate the treble, or an acoustic term in the sound field that has a spatial separation between instruments. At this time, the high frequency illumination can be extended to 15 kHz to 20 kHz. The antonyms are "dull" and "thick". Very abstract words, not a sense of space. It is more suitable for listening to large books or programs that are played in larger venues. It is a kind of high frequency and relatively scattered movement. Low frequency extension: refers to the lowest frequency that the audio device can reproduce. It is used to determine the extent to which the sound system or speaker can dive when replaying low sound. For example, the low-frequency extension of a small ultra-low dynamic tank can reach 40 Hz, while the large ultra-low dynamic tank dive to 16 Hz. Bright: refers to highlighting the high frequency range of 4kHz-8kHz, where the harmonics are relatively stronger than the fundamental. There is nothing wrong with the brightness itself. The live concerts have bright movements. The problem is that the brightness is well-controlled and the too bright (or even howling) is annoying. Sound quality: The term sound quality is not abstract. When you open a radio to listen to music or news, when you feel it sounds, the radio broadcasts the announcer's movements sweet and layered. The distortion is small, the treble is bright when the music is broadcast, the voice is low, and the reverberation is good. You can't help but admire the surprise: "This radio sounds good!" Sound quality is the most basic and broadest comment term for audio equipment. Tone: The movement will be the same as the light, but it is not seen with the eyes, but with the ears. The warmer the sound, the softer the sound, and the harder the sound, the harder it is. The sound can be depicted with the eyes of “beauty” and “prestige”. For example, when listening to the violin, you can say that the sound of the violin is really cold or really warm. Sound field sense: This includes the shape of the sound field, front and rear orientation, height, width, depth, etc. These items can be expressed in a concrete way, that is, the sense of presence of the sound field. This is the sense of the listener and the speaker's position, the space is connected to each other to reach a more beautiful and appropria
I have been in contact with the Internet for nearly ten years. From the initial simple technology to the later comprehensive development, the road has been long and witnessed the fierce development of the Chinese Internet in the past ten years. I recently came here and looked at the e-commerce chat in the circle of friends. The heat is in full swing, there is no e-commerce, the company will never have a day in general, the current, e-commerce is hot to hot, but your business is really suitable for e-commerce road? Even if it is suitable, then I would like to ask a few questions: 1. What is your road to e-commerce? Second, what is the purpose of your e-commerce? Is it just for sale? 3. Is your company prepared to take the road to e-commerce? The Internet is playing marketing rather than sales. The two are related but they are two different concepts. If you only sell by sales, the e-commerce road will be difficult to achieve in the long run! (The above are some of my personal views, only to share with you) The vast market does not mean that online demand is huge. The biggest difficulty for traditional enterprises to go online is the change of entrepreneurial thinking and the strength of support. The key factor behind this lies in the fact that consumers’ online demand is not imagined. So big. For example, the fresh e-commerce that is being fired now is popular, and the food market is indeed very large. However, whether consumers are demanding on-line consumption is a problem worthy of attention. For example, my mother may spend 500 yuan per month on fresh food, but she will not buy it online on the market... For a traditional company, it is necessary to investigate the online market in advance. And then put in the corresponding resources, if you blindly enter this market, in the current consumer user habits have not been cultivated, it is likely to lose the blood, you can think about the people around, how many people go Buying fresh food online? The concept of fresh e-commerce is very hot, and the market demand is also great, but how is its online marketing effect? Stepping into an unfamiliar market, and working with the platform is relatively stable, once contacted a company, its strategy of e-commerce road is relatively conservative. The company has established independent e-commerce departments in Beijing, Shanghai and Guangdong. The e-commerce department does not have to be responsible for online sales and marketing tasks, but mainly through cooperation with mature e-commerce platforms such as Jingdong, Yixun and Dangdang. The way the platform is delivered. This aspect reduces the operating costs of enterprises, and on the other hand, it eliminates the blind follow-up of traditional enterprises because they are not familiar with the Internet. Personally, no matter what kind of purpose the enterprise needs to enter e-commerce, it must not blindly follow the concept or idea to lay out e-commerce, but must act cautiously on its own goals at this stage. Similarly, the e-commerce channel is currently a simple complement to the existing channel for this company. The company actually attaches great importance to the future development of online business, but they are very entangled in how to choose the e-commerce staff. On the one hand, employees in the company have a certain number of years of internal work. Compared with those recruited from the outside, these old employees are more familiar with corporate culture, enterprise products and various processes, and can describe their products to customers faster. On the other hand, they are very confused about whether these internally promoted employees can adapt to the high-tempo life in the Internet e-commerce environment. The traditional offline thinking can not be changed in a short time. There is also a very interesting thing. The recruitment standard of this company's e-commerce department is that it needs to be familiar with the Internet. It does not emphasize whether it has offline experience. In their view, the online business must be handed over to the Internet-savvy talent. Better done. The challenges brought by the different online and offline price systems often cause great damage to the price system of manufacturers. Many e-commerce companies fight price wars, and sometimes they use bloody discounts to attract consumers. This makes online Commodities are often much cheaper than offline, which often leads to strong opposition from offline channels. Take the company mentioned above, the price on the e-commerce platform such as Jingdong and No. 1 shop is more favorable, and at the same time, it provides a variety of special discounts for the e-commerce platform. The amount of money users spend on one-time purchases is not very high, but through this extra large package, it is often possible to increase the amount of single consumption. Under the circumstance, this kind of extra large packaging is very cumbersome for consumers and consumers to take
Stages of development of electronic products from development to marketing New product development process from development to listing Product conception and selection - mainly seeking product ideas Product Concepts and Assessments - Focus on Market Analysis and Strategy Product definition and project plan - the basic stage of product development work ?Design and development - product development by program Product testing and verification - the focus is on testing and acceptance Product launch - do a good job before the listing Product conception and selection This stage is mainly to seek product ideas. Not every enterprise regards this stage as the formal stage of the process. However, it is an inevitable stage of the product innovation process, because any one of the productization ideas is from Processed from numerous ideas, the process management at this stage is often very open. They can come from the customer partner after-sales market manufacturing and R&D. These information from various channels constitute the most original concept of the product. Product concept and assessment The focus of this phase should be on analyzing market opportunities and strategic feasibility, mainly by quickly collecting some market and technical information, using lower cost and shorter time to analyze the feasibility of financial manufacturing in the technology market. And assess the size of the market, the potential of the market, and possible market acceptance, and begin to shape the product concept. At this stage, only a small number of people participate in the project, usually including a project sponsor and several other assistants. Under normal circumstances, this phase is completed in 4-8 weeks. Product definition and project plan This phase is the basic stage of product development. Its main purpose is to define new products, including definition of target market, definition of product concept, product positioning strategy and description of competitive advantage. It is necessary to clarify the functional specifications of the product and the description of the product value. Other aspects, determine the feasibility of product development, conduct a rigorous investigation of the Scoping stage estimates, and complete the planning of the subsequent stages. Of course, this stage does not require detailed product design. Once this stage is over, this need to be Estimate the resources, timelines and funds of the product. This phase involves a lot more activities than the previous one and requires a multifaceted resource and information input. This phase is best handled by a cross-functional team, which is a core member of the final project team. New Product Design and Development Project Manager Alliance Article The focus of this phase is on the physical development of the product according to the established plan. Most of the specific design work and development activities are carried out at this stage, and the opportunity and feasibility of the product are not analyzed. At the same time, this stage also needs to start some work in testing, production, marketing and support systems, including the development of production processes, the release of planned products and the construction of customer service systems. In addition, market analysis and customer feedback work are also In progress, there are financial analysis reports that need to be continuously updated, and intellectual property issues must be resolved. Product testing and verification The focus of this phase is testing and acceptance. The activities in this phase include product testing and user testing (B testing) within the company, and even small-scale trial production of the product and market trials. Of course, this stage still needs to be updated. The financial analysis report, the sign of this stage is the successful adoption of product testing, completion of marketing plans, and establishment of a viable production and support system.

Innovative intelligent electronic product development The trend of electronic product design continues to develop. At present, FPGA plays an increasingly important role in the design of embedded systems. The interdependence between programmable logic design, embedded software design and board design is increasing. However, there is still no small challenge for designers without FPGA experience: they must either be familiar with professional languages and low-level development boards; or they need expensive professional design tools. To solve the above problems, the industry is looking for new ways to reduce the complexity of FPGA development and the requirements for professional skills. "The current direction of development is a high-level FPGA development system," said David Read, technical director of Asia Pacific at Altium. The new FPGA development system avoids the use of the HDL language and reduces the knowledge requirements for the underlying component architecture; Being copied or reverse engineered, the “soft” elements in the design are easily updated to achieve continuity in the design process. He pointed out that the soft design designed with a new generation of development tools can be independent of the pre-specified hardware platform; moreover, the design can continue in the final hardware platform, even if the product has been handed over to the customer. At present, FPGAs are evolving toward the trend of platformization. By using the FPGA platform, the entire SoC system can be rapidly developed. In order to simplify FPGA-based development and accelerate the development of next-generation interconnected intelligent electronic products, Altium has launched a new FPGA development board, the NanoBoard3000. “The NanoBoard 3000 provides engineers with all the hardware and software needed to develop FPGAs, as well as ready-to-use IP; designers can launch pure 'soft' prototyping with NanoBoard, then deploy it on-site on the NanoBoard or seamlessly transfer it Designed for PCBs.” Read, “This means that designers can focus more on the intelligence and differentiation of creating products.” With the NanoBoard 3000, electronic designers can build next-generation electronics designs using "soft" processor-based systems in FPGAs. “Even engineers without any FPGA expertise can use the NanoBoard3000 and AltiumDesigner to build, test, and implement FPGA-based embedded systems.” Read further shows that engineers can use without writing HDL or low-level driver code. Off-the-shelf components to add everything needed to create an FPGA-based embedded system, such as processors, memory controllers, peripheral modules, and software stacks. Currently, the first NanoBoard3000 uses the XilinxSpartan3ANFPGA. In addition, two NanoBoards with Altera and Lattice FPGAs will be introduced. It should be noted that "in these three alternative NanoBoard products, the FPGA is fixed." Read emphasizes, "This is different from the NanoBoardNB2, which uses an interchangeable FPGA daughter board that can be used in the prototyping environment at any time. Comparative test." Altium also added an instant deployment option for the NanoBoard3000 FPGA development board. Designers will be able to move the FPGA design directly from the concept creation process to the deployment implementation phase without having to create a custom PCB. “With the NanoBoard 3000, designers can complete FPGA prototyping in a matter of days.” Read showed a stage lighting control solution developed by the NanoBoard 3000, which enables the free rotation of the stage lights and the transformation of the projected pattern through touch control. "With the latest deployment options, designers can deploy their products in minutes." Using modular architecture, designers can quickly deploy FPGA-based designs in the NanoBoard 3000 in a variety of ways. Such as on the desktop, on the wall, in commercial or industrial applications, multi-board design applications, as well as TFT display on the housing, or without a TFT display. With the NanoBoard3000 enclosure, designers can start a true “soft” prototyping and then deploy it on site. In addition, "AltiumDesigner also provides designers with the possibility to upgrade their 'soft' design licenses to board-level licenses to complete custom PCB designs," Read added. "The 'soft' design by NanoBoard 3000 is available. It is easily transferred to a custom PCB." Thermometer Electronic product development

The juicer is a machine that can quickly squeeze fruit and vegetable juices into small juices. It was invented by Dr. Norman Walker in 1930. The doctor was known for inventing the world's first juicer and was known as the father of the active juicer. On this basis, the designers later improved the juice machine with different styles and different principles. There are two main types of juice drinkers: one is a family with children or the elderly, the children are easy to picky eaters and the old people have bad teeth, and their juices can satisfy their intake of adequate nutrition; the other is the pursuit of fashion and quality of life. Young people, juicers meet their needs for individual tastes. With the improvement of the quality of life, the consumer's mentality begins with the most basic needs of life and transitions to a nutritious and healthy taste life, which makes it possible for the juice machine to become more popular. Whether it is a juice machine or a food processor, it is in the market introduction period. For most consumers, it is still a luxury. How to guide consumers' consumption concept is very important. The juice machine is mainly composed of motor, knife net, main machine, juice outlet, juice cup, pomace bucket and top cover. The motor and knife net are the main core components. After the juice machine starts the machine, the motor drives the knife net high speed. Rotate. Pushing fruits and vegetables from the feeding port to the knife net, the spikes of the knife net will chop the fruit and vegetables, and under the effect of the centrifugal force of the juicer produced by the high speed operation of the knife net, the pomace flies out of the knife net into the slag box, while the juice wears The knife net flows into the juice cup. The basic function of the juicer is to squeeze the juice. After that, some multi-function juicers can also be used to make soy milk and fruit agitation. According to the working principle, the juice machine can be divided into two types: high-speed centrifugal juice machine and low-speed squeeze type juice machine. The working principle is as follows: High-speed centrifugal juice machine: This is the most common type of juice machine on the domestic market. Its working principle is to use the high-speed rotation of the knife net every few thousand revolutions per minute to crush the fruit, and the powerful centrifugal force causes the juice to flow into the juice cup. The slag is broken into the slag bucket; Low-speed squeeze juice machine: This juice machine is also loved by many people. Its working principle is to rotate the fruit at a low speed of 80 rpm by an internal screw. The net flows out and the pomace is discharged from the slag discharge port.
The disinfection cabinet was invented by Chinese people in Guangdong in 1988. The disinfection cabinet is the first electrical appliance product invented in China. It is widely used in hotels, hotels, restaurants, schools, military units, canteens and other places. More and more Chinese families are paying attention to the importance of disinfection cabinets, and will be one of the household appliances in the future. Only good disinfection equipment can ensure that people's food intake is healthy. As one of the important electrical appliances in modern kitchens, the disinfection cabinet will continue to grow steadily in the next few years, and the disinfection cabinet industry is also becoming more mature. Disinfection cabinets, what products the Chinese have developed themselves, along which development trajectory will advance in the future? Trend 1. The embedded market share will rise and the price will fall. Trend 2: Disinfection cabinets with anti-virus function are getting more and more attention. Trend 3: Disinfection cabinets with multiple disinfection methods are the mainstay of the market. The working principle of the disinfection cabinet is to use the high-pressure silent discharge device to generate ozone molecules, and achieve the sterilization purpose by the strong oxidation generated by the reduction of ozone molecules into oxygen molecules. The temperature inside the disinfection cabinet must reach 125 ° C, and it can be kept for 10 minutes to kill the harmful bacteria and hepatitis bacteria. The disinfection cabinet is mainly composed of a box body, a temperature controller, a far infrared heat generating tube, a button, a water receiving box, an indicator light, a dish rack and a chopstick holder. Main types of disinfection cabinets 1, according to the use can be divided into: commercial disinfection cabinets and household disinfection cabinets. 2, according to the disinfection method is divided into: a high-pressure steam utensil disinfection cabinet that disinfects the utensils by high-temperature steam; The electric hot food disinfection cabinet is heated by the electric heating element to disinfect the disinfection apparatus; Ozone utensils disinfection cabinet disinfection cabinet for disinfection of utensils through ozone; UV disinfection cabinet UV disinfection as one of the means of disinfection of utensils, disinfection cabinets only rely on ultraviolet disinfection is not suitable for disinfection of utensils; A combination disinfection cabinet is a disinfection cabinet that combines two or more sterilization methods to disinfect the utensils. 3, according to the disinfection effect is divided into: One-star disinfection cabinet (*) The killing rate of E. coli Staphylococcus aureus should not be less than 99.9%, work requirements. The ozone concentration should not be less than 20 mg per square meter for 20 minutes; Two-star disinfection cabinet (**) a) The logarithm of the killing of Escherichia coli Staphylococcus aureus should be ≥ 3 ( ≥ 99.9%); b) The titer of poliovirus infection (TCID50) ≥ 105 inactivation log ≥ 4.00.

The doctor was known for inventing the world's first juicer and was known as the father of the active juicer. On this basis, the designers later improved the juicer with different styles and different principles. In this huge market in mainland China, the juicer industry is in a period of rapid growth. The popularity of juicers in China is still very low, but it has gradually become familiar with consumers, and sales growth has been relatively rapid. There are two main types of juicer consumer groups: one is a family with children or the elderly, the children are easy to picky eaters and the old people have bad teeth, and their own juice can satisfy their intake of adequate nutrition; the other is the pursuit of fashion and life. Young people of taste, juicers meet their needs for individual tastes. The market economy of the juicer industry will become more intelligent, aesthetic and professional. At the same time, consumers' consumption concept will gradually change to a healthy, fast and convenient direction. For new kitchen appliances, Chinese juicers The industry has a large space for development. The working principle of the juicer is to rotate the fruit at a low speed of 80 rpm by an inner screw. The fruit juice is oozing through the filter and the slag is discharged from the slag discharge port. The juicer has basic functions such as juice extraction, soy milk, grinding, and fruit agitation. Main types of juicers According to the shape can be divided into: single cylinder juicer, two cylinder juicer, three cylinder juicer, four cylinder juicer, round cylinder juicer According to the function, it can be divided into: agitating juicer, spray juicer and juicer juicer.

There are some auxiliary or conceptual smart products designed for people with disabilities. Good technology and design are not just for creating products for the public. People with disabilities also need the help of excellent smart products. Today, I accidentally planed to get such a smart bracelet. I got the concept of the 2013 Red Dot Award, which was specially designed for people with hearing impairments. According to online information, as of last year, the number of hearing-impaired people in the world reached more than 3 million. This is definitely not a small number. I know that people with hearing impairments generally use sign language, but in general, sign language only It is suitable for communication between people who are also hearing-impaired. If you are not studying the sign language, you can't understand sign language. This is definitely a bug for us to get through the barriers between people! How can we let us and The barrier-free communication between deaf and dumb people is undoubtedly dependent on the power of technology. A smart sign language translation bracelet designed by three Asian designers. It can use a set of algorithms such as EMG sensor, gyroscope and distance sensor to analyze the movement of sign language. The hearing impaired people follow the standard of sign language. When the action moves their hand, the bracelet can convert these gestures into voice or text data for display to the other party in real time. When you connect to a mobile phone by means of NFC or Bluetooth technology, you can also directly send the translated information or voice to the other party's smartphone. Because the sign language requires two hands to combine the gestures, this bracelet is a pair of left and right hands. After the sign language of the hearing impaired is translated, what we said can also be translated to the hearing impaired through this stuff. I think this function is a bright spot, very good and powerful. It can record the words of the other party through speech recognition one by one, and then the built-in sign language gesture image will be displayed on the LED display on the bracelet, so that you can communicate normally! Because this thing is still in the concept stage, so the real use effect is still not known. However, the current technology is completely achievable, and it is necessary to sort out a mature application data in order to make this device work well. Look forward to more such types of products appearing. We are now able to achieve simple and accessible communication between different languages through some applications on smartphones. After the communication between us and the hearing impaired is also opened, the world of communication is perfect.
