Can hold the development of speaker and speaker technology in the future direction

At present, there are more than 280 professional manufacturers engaged in the production of speakers and speakers (according to AUDIO), the production of products have a thousand. The speaker and the speaker system as the end of the audio playback, it's quality, will directly affect the entire sound system to play a sound effect. Foreign companies engaged in the production of large companies have invested great power, and constantly develop new speakers to meet new products, to meet the requirements of different environments and different audio equipment.

　　In recent years, with the development of digital audio technology, the requirements of the speakers are also more demanding. In order to meet the needs of the development of technology and meet the needs of consumers, the world famous speakers company are dedicated to improving the performance of the existing speakers, and research and development of new speakers for new materials, new technology and the use of new design method.

　　Now the world knows my big company's speakers and its system technology status, characteristics and unique new technology introduced as follows:

　　1.Technical status of foreign speakers and speakers

　　1.1 Professional speakers

　　Is mainly used for loudspeaker and loudspeaker box film, stage, halls, sports venues and other occasions. In recent years, with the development of new materials, new technology, new structure, new technology, the application of stereo technology, digital technology, CD and VCD, the professional speakers and their systems have made great development, new products continue to emerge. The new technology, new technology, new technology, new technology, new material, new technology, new material, new technology, new material, new technology, new material, new technology, new material, new technology, new material. JBL, EV, BOSE, KEF, TONNY,, Panasonic, pioneer, MITSUBISHI, YAHAMA and TOA, have been introduced in recent years. They are characterized by a large, high power, high efficiency, high efficiency, and generally 98-100dB, wide 200W. In order to achieve the above characteristics, the world famous speaker manufacturers The Eight Immortals Crossing the Sea Gexianshentong.

　　The main methods are as follows:

　　First, the use of new magnetic materials, the use of new magnetic circuit design method. Such as JBL company adopted the SFG magnetic circuit design, which contains a magnetic flux balance, reduce the amount of driving source inductance and heat conduction of the new structure. The use of magnetic materials and its energy product is more than 3.6MGsOe. This makes the capacity of the speaker to withstand the increase in the capacity of the playback of the bass, strong, strong.

　　Second, the new materials, aerospace titanium material such as the use of treble loudspeaker, because ti e - P than companion materials superior, suitable for manufacturing high-quality tweeters diaphragms. The high frequency of the high frequency and high frequency of the titanium diaphragm is greatly improved. The bass speaker uses a laminated high density composite paper bowl. Because of the high percentage of the flat wire and the high utilization ratio of magnetic circuit, the sensitivity of the voice coil is high. The technology is invented by JBL company, and other major companies are following the example.

　　Third, using the new horn, long-term use in professional sound reinforcement in the exponential horn loudspeaker has been new directivity horn replaced. Such as pointing to the key technology of the horn in horn with different shapes of side wall and become complex, discontinuous function due to past simple linear, exponential, to achieve a constant directivity.

　　Fourth, the use of computer CAD, CAM and CAT technology, the use of modern technology to tap the potential of traditional speakers, so that professional speakers products excellence. Representative products, such as MR company's JBL professional speakers speaker series, SR professional speakers speaker series.

　　1.2 AV speaker

　　Mainly refers to the for home hi fi audio system combination, karaoke OK karaoke, dance halls and home theater sound system of loudspeakers. AV speakers have made great progress in recent years, new products continue to emerge. All the world's major speakers have introduced various forms of AV speakers. They not only have advanced technical performance, but also from the practical modeling, improve sensitivity, expand the dynamic range, broaden the playback frequency band and good transient response and other technical characteristics.

　　There are two common frequency loudspeakers: tweeters with a 8 or 6.5 inch woofer Yingyu plus ball. Because of the low frequency of a loudspeaker, the speaker unit has a wide range of piston vibration and does not appear to split the vibration, so as to ensure the ideal directivity and phase characteristics. The company according to the pursuit of enthusiasts bass and have developed dumbbell type loudspeaker box, with two 8 inch or 6.5 inches bass unit between the clip a dome tweeter, aimed at strengthening the bass. Three way frequency loudspeakers: added a midrange unit on the basis of two frequency, the utility model has the advantages of is make full use of each unit of piston oscillation frequency, reduce the distortion, improve the power bearing capacity to love.
