Miniaturized sound system. Micro desktop combination acoustics has a long history of development, in more than 10 years ago has appeared in the advanced ultra-small combination acoustics. But as a result of listening to sound horn, stereo record player, recording booth did not solve very well, so has been staying in the lower grade. In order to create a compact sound world, not only from the amplifier, control components, left and right speakers work hard, but also from the tuner, CD player and recording card.

Digital audio. Digital technology is a kind of new technology, so digital audio is developed when solving the problem of distortion of analog audio noise. After the audio adopted digital technology, the recorded digital signal from the sampling frequency to the quantitative characteristics, has a high resolution, no color jitter, is a very clear image. And can be interchangeable with the host computer, which is incomparable with analog recording and video equipment. Digital recording CAN put the time, the name, address together INPUT BELT, the use of miniature keyboard to complete the catalog work, change the number of tracks, plus remote control function, so that you can automatically search the required tracks, easy to use. Integration of video and audio equipment. With the development of electroacoustic technology, film and television technology and computer technology, digital audio system can be integrated into multimedia film and television audio system. Such a system can hear all kinds of signal input and function conversion to add all kinds of needs in the input end, through computer processing can make people see all kinds of images and hear all kinds of sounds.

The appearance of ultra-thin flat speaker and flat speaker makes it possible for family combination (home theater, background music) to develop towards ultra-thin direction. Since 1998 to 2012, flat speaker has experienced several stages of development. In 1998, Sannuo introduced flat speaker, which was inherited and developed by Hualong Di Sound (DS) and Towek (TVC). In 2008, Chengdu Tianxiang (HVS) developed China's own tablet pronunciation technology "VT" called "the fifth generation of tablet pronunciation technology", the development of tablet sound technology in China is becoming more and more mature, thin murals ultrathin sound in the family use tends to mature.
