噪声是随身听及一切音响设备的大忌,任何随身听的噪声可分为三种: 其一是“咝咝”噪声,但能听出放音声。原因和排除方法是:①固定电路板机心的螺钉松动引起,或电路板地端与机体部分的连线断开。只要将螺钉拧紧,或接上连线即可排除故障。②磁头磁化严重,消磁即可。③放大电路的前置部分或集成电路元件变质引起高频振荡产生“咝咝”声。检查各部分元件,若元件无损坏,“咝咝”声还没消失,则需要更换集成块。
Noise is the taboo Walkman and all audio equipment, any Walkman can be divided into three kinds of noise: one is “咝 咝” noise, but can hear the sound of the sound. Reasons and remedies are: ① fixed circuit board movement caused by loosening of the screw, or circuit board to the body part of the connection and disconnect. Just tighten the screw, or connect to the line to troubleshoot. ② head magnetization serious, degaussing can be. (3) Amplification of the front part of the circuit or the deterioration of integrated circuit components caused by high-frequency oscillation, “咝 咝” sound. Check the various components, if the components are not damaged, “咝 咝” sound has not disappeared, you need to replace the manifold.
