The development of human science and technology is quite rapid, from the early vinyl record player, black and white TV to the current multimedia speakers, LCD TV and smart TV, as well as various other household appliances around our lives, it can be said that over time has accumulated Earthshaking changes have taken place. At the end of this year, let us review the development and development of the audiovisual and home appliance industry in 2014. TOP1 active noise reduction application vigorous performance is the key point At this stage, environmental pollution is not just referring to water pollution and air pollution. Noise pollution is also a matter of great concern. In the practice of human prevention and control of noise pollution, two major schools of technology have gradually formed. One is passive noise reduction (also known as Physical noise reduction), one is active noise reduction (also called active noise reduction). The technical characteristics of passive noise reduction are to use various characteristics of materials to isolate noise sources, dampen and dampen the noise, etc. Passive noise reduction technology has a significant effect on high-frequency noise, but for a large number of ubiquitous low frequencies The treatment of roar is not good. In the face of low-frequency noise, active noise reduction technology has its unique advantages, and it is gradually starting to start. Especially as consumers have higher and higher requirements for mobile communications and multimedia applications, the competition for electronic products is becoming increasingly fierce. Experience has gradually become an important factor in product competitiveness, which has also contributed to the rapid growth of active noise reduction technology applications. TOP2 who will occupy the leading role in the TV industry in 2014 As a TV practitioner, I think that the concept of 4K will be a very important development direction for TV sets in the future. Next, I will talk about it in detail. For the TV industry, the past few years have really attracted attention: from the popularity of 3D TV in 2012 to the outbreak of smart TV last year, then for the coming 2014, which word will be the protagonist? TOP3 MEMS microphone: the future of hearing aids Due to the aging population and a significant increase in the number of people with hearing loss, the hearing aid market continues to grow, but its conspicuous appearance and short battery life have caused many people to lose interest. As hearing loss becomes more common, people will look for smaller, more effective, and higher quality hearing aids. At the front end of the hearing aid signal chain is a microphone, which detects speech and other environmental noise. Therefore, improving audio capture can improve the overall performance of the signal chain and reduce power consumption. TOP4 TV industry: The key words in 2013 are smart TV and 4K, and 2014 is to fight for soft power In the past 2013, you must have remembered the keywords of two TVs, one is smart TV and the other is 4K. Both of these keywords need to have strong soft power, because TV hardware in 2014 may not be a big surprise. Remember that smart TV is because a group of hyped Internet companies such as Xiaomi and LeTV have entered the TV industry. Due to its catfish effect, the entire industry has become very active, from the domestic six tigers in the TV industry to the recent transfer from PC. Lenovo has focused on smart TVs.
