Three development trends of speaker technology

On the current situation, there are three types of speaker technology development trends:

　　1、The speakers will continue to develop small, low distortion, high sensitivity, large dynamic range, broad band and good transient response.

　　Needless to say, the trend is small, stylish compact appearance, excellent portability, unparalleled excellent sound quality will be the first to bear the brunt of the demand. Ultra-thin speaker for notebook computers, mobile phones have already become a reality, and for LCD and plasma televisions and cars with thin speaker, there are also quite a number of manufacturers have been or are officially put into heavily in research and development. We all know that the phone has been embedded in more features, such as MP3 player, recording, chord ring tones, multimedia video player, stereo surround music, etc., these features are the new selling point of mobile phone. At the same time, the introduction of iPod will also lead the new trend of miniaturization. According to relevant information, said the next two years, iPod sales will exceed 4. For the rapid development of the micro loudspeaker provides unlimited power, our industry only R & D and production of smaller size, greater power, wider frequency response of the speaker to better adapt to the market demand.

　　2、Professional audio and car audio will still be a long stroke, high power, high sensitivity, wide directivity, low distortion direction. On the car super bass speakers, the European and American countries will be 12 inches ultra low to do a one-way amplitude 50mm, power 2000W, and even 4000W, sensitivity over 100dB, its wide directivity can make the listener feel the whole body and not hear the low frequency. In view of its structure, it can be found in the magnetic circuit design and film materials have a greater breakthrough.

　　3、Flat panel loudspeaker although has been available for several years, development is relatively slow, the key is the quality improvement and frequency response broaden hinder its development.

　　As this problem is resolved, the tablet speaker will become one of the mainstream products of the speaker market. It is understood that PHILPS has made a new breakthrough in this regard, they apply for the patent program is called SFD Tweeter TM 3D (SFP 3D high frequency supplement ring), in fact, is a metal shield in the soft flat screen surface, with a diameter of 3mm close to and slightly higher than the net surface mounted similar ornaments of silver metal ring, which is a patent application is to increase the high frequency response of SFP. When the diaphragm is driven by a sound, the metal ring becomes a passive high frequency speaker, and the response of the high frequency section of the 1.1 Hz or more than the middle frequency is obviously improved and improved.

　　In addition, PHILPS is still making the flat panel speaker sound frequency curve smoothing problem, optimizing the magnetic circuit design, widening the directivity and many other improvements in the technology parameters of the flat panel has done a lot of research work, and achieved remarkable success. I believe that with the progress of technology, flat panel speakers with its beautiful shape design and sound quality will be a great place to shine.

　　In addition, as in other industries, electronic industry and the general trend of green manufacturing. Our country to implement the EU RoHS directive into the recycling of waste electrical and electronic products have 10 major categories of 145 kinds, covering almost all of China's exports of electronic and electrical products, of course, speakers and their systems are no exception. At the same time, combined application of electronic technology and electronic technology needs new breakthrough.

　　To sum up, the overall goal of the development of speakers in our country should be comprehensive with the European and American new technology, strengthen exchanges and cooperation between Europe and the United States, to promote new materials research and speaker design progress, and vigorously promote the spirit of independent innovation, strengthen the industry integration, to eliminate vicious competition, so that they have a certain economic strength to engage in research and development and innovation, in the above several aspects to win a new breakthrough. At the same time, combined with characteristics of miniaturization, strengthen the supporting and conformity and electronic technology, to enable the machine to the rapid increase in the level of, make our country changed from acoustic power into acoustic power.
