本文介绍了电视机中伴音系统的发展,从传统的伴音系统发展成“双伴音/立体声”方式,出现了丽音系统,形成了同保真立体声效果。然后又引入了环绕声技术,以及全数字处理方式,达到了真正的音响效果。文中给出了实现其功能的典型电路,以及今后的伴音发展趋势。
This article introduces the development of the sound system in the TV. From the traditional sound system to the “double sound / stereo” mode, the Miyaura system appears, forming the same fidelity stereo effect. And then introduced the surround sound technology, and all-digital processing, to achieve a real sound. The article gives a typical circuit to achieve its function, as well as the future development trend of sound.
