The three major development trends speakers technology

The present situation, there are three loudspeaker technology trends: a, speakers will continue to miniaturization, low distortion, high sensitivity, wide dynamic range, wide-band and good transient response. There is no doubt that small is the trend, the fashion and compact appearance, excellent portability and unmatched sound quality will be excellent first demand. Ultra-thin speaker for laptop computers, mobile phones have become a fact, but for LCD and plasma TV as well as automotive thin speakers, many manufacturers have already or formal research and development investments. We all know phone embedded more features such as MP3 players, sound recording, Polyphonics, multimedia movie playback, stereo surround music, these features is the new mobile phone now. At the same time, the introduction of the iPod will lead the new trend of miniaturization. According to the information that this year and iPod sales will exceed $ 400 million. While these are miniature speaker's rapid development provides unlimited power, we trade only in development and production out of smaller, more powerful, frequency response wider speakers to better suit the needs of the market. Second, the professional audio and car audio will still be to long stroke, high power, high sensitivity, wide directivity and low distortion. Car subwoofer, Europe and the United States will be 12-inch subwoofer do one-way amplitude 50mm, power 2000W even more than 100dB 4000W, sensitivity, and its width direction can make listeners feel to the whole body and not listen to the low frequency of low frequency. An overview of the structure can be found in the magnetic circuit design and diaphragm materials have a major breakthrough. 3. flat speakers have been published over the past few years, the development is still relatively slow, and the key lies in its quality improvement and enhance and broaden the frequency response of hindering their development. If this issue is resolved, flat panel speakers will also be a speaker for one of the mainstream products. It is understood that Philips has achieved a breakthrough, they apply for patent project called "3D SFD Tweeter TM (addition of 3D SFP-frequency ring)", in fact it is a soft flat panel speakers on the surface of the metal protective NET, with a diameter of 3 mm to keep abreast of and slightly higher than the net surface installed similar decorations of silver metal rings, this patent application is to substantially improve the SFP soft flat panel speaker key high frequency response. When the diaphragm is driven to voice, the metal ring becomes a passive RF loudspeaker, 1.1 million cycles per second over medium-high frequency response immediately visibly improve. In addition, Philips has also making flat panel speaker frequency response curve smoothing problems, optimized magnetic circuit design, broaden the directivity and many other improvements in flat-panel speaker technology parameters have done a lot of work, and has achieved remarkable success. Believe that as technology advances, flat panel speaker, with its beautiful shape design and sound quality will be great splendor. In addition, and other industries, electroacoustic green manufacturing industry is the trend of the times. Implementation of the EU RoHS directive into recycling waste electrical and electronic products has 10 major categories 145, almost all exports covered China's electronic products, of course, the speakers and the system is no exception. At the same time, the electronic and electroacoustic technology portfolio of applications also need new breakthroughs. To sum up, our overall goals for the development of the speakers: should be comprehensive and Europe and the new technology standards, the strengthening of European and American international exchanges and cooperation, contributes to our new material research and progress in the area of speaker design, to carry forward the spirit of innovation, industry consolidation, eliminating competition, so that they have a certain economic strength in research and development and innovation, in the above areas for a new breakthrough. At the same time, combined with the characteristics of miniaturization, strengthening and supporting electronic technology and integration to rapidly improve the level of the machine, which has made China the electro-acoustic power into electrical power.
