提高音响系统的音质在不少技术人员心中似乎觉得已没有多少新概念了,只有用高档芯片高档设备才行。但国外一些大品牌的MP3、组合音箱或平板电视机的伴音等音质要比中国国产品牌好,除芯片器件好之外,其实还有各自的新招术。从电源电压着手改善信噪比为减轻电源负担,减少能耗,延 Improve the sound quality of the audio system in many technical staff seems to think there is not much new concept, and only use high-end chip high-end equipment Caixing. However, some foreign brands of MP3, speaker or flat-panel TV sound quality better than the Chinese domestic brands, in addition to the chip device is good, in fact, there are their own new tactics. From the power supply voltage to improve the signal to noise ratio To reduce the power burden, reduce energy consumption, delay
