the ability of adjusting and balancing natural tones Good speakers should be able to truly and completely reproduce the original attributes and characteristics of musical instruments and sounds. Perhaps the most important performance is sometimes the precise tone balance. Sound should give a feeling of smoothness and no touch, and there is no obvious distortion of tone and treble description. The tenor and treble are not too "empty" or "repressed" special feelings. Use a wide range of instrumen

Maintenance Knowledge 1. Correctly set the sound card output mode. Generally we use the integrated AC97 sound card, the back panel of the chassis has 3 interfaces, we normally use are active speakers, so should be plugged into the line output of the interface (green), and the red interface is connected to the microphone, and the other is the line input (analog input) interface (blue). Maintenance Knowledge 2. When powering on, shutting down, restarting, etc., the

Android Bottom -up headphone Plug and audio channel switching instanceBecause headphones are used as separate headsets, the events are reported separately. The detection of headphone jacks on the Android system layer is based on /sys/class/switch/h2w/state values (in 4.4.4_r2 For example in Wiredaccessorymanager.java).A switch class -based h2w switch is implemented in the kernel as long as it is "true or false" . the Android system will be able to monitor the plug and unplug information.
