Into the information age, with mobile communications, home theater, multimedia, the rapid development of digital audio and video terminals, electroacoustic device industry usher in a golden development. Advanced design software and equipment, measurement, acoustic technical level, changing the traditional electroacoustic device performance optimization, new electroacoustic devices such as digital, silicon integrated product emerge in endlessly. High fidelity, chip, miniaturization, thin, low power consumption, high power, multi-function, element as a new development trend of electroacoustic device. Predict that in the next few years audiovisual products about increasing at the rate of 20%, the resulting market the huge demand of electroacoustic device. Because of this, a large number of domestic excellent electroacoustic device production enterprise rapid rise, gradually become China and even the best global electroacoustic device industry!
