Abstract

This intelligent volume switch method used in multi media protects auditor's ears and solves the problem that the original volume during switching between various playback sets cannot accommodate to the hearing habit. This invention recognizes the type of playback sets selected by users according to the different resistant value of various playback sets. It keeps the records of the volume values that the user used to apply and regulates dynamically the volume output.

Description

technical field [0001] The present invention relates to a method for intelligent volume switching for multimedia, in particular to a method capable of automatically detecting the type of sound playback device and recording the volume the user is accustomed to using to dynamically adjust the volume output. Background technique [0002] The equipment that can play music and sound is very common now, and the user will inevitably encounter the problem that the initial volume does not conform to the listening habit due to the switching of the playback device during use. During the playing process, the user may choose different devices to play the sound, such as speakers, earphones and so on. When the speaker is used to play the sound, the volume may be adjusted higher, and then when the user wants to listen to music with the earphone, because the previous volume is adjusted higher, when the earphone is inserted, the output volume will make the user feel uncomfortable. Comfortabl...
