Abstract

A volume adjusting device is used for adjusting the volume of an audio player of a mobile device and comprises an environmental noise acquisition device, a first comparison unit, a speed sensor and a second comparison unit, wherein the environmental noise obtaining device is used for acquiring environmental noise waveform data and computing an intensity value of the environmental noise waveform data, the first comparison unit is used for comparing the intensity value of the environmental noise waveform data with a sound intensity threshold value and outputting a comparison signal if the intensity value of the environmental noise waveform data is larger than the sound intensity threshold value, the speed sensor is used for detecting the movement speed of the mobile device, and the second comparison device is used for comparing the movement speed obtained by detection with a speed reference value according to the comparison signal and outputting a first volume adjusting signal to the audio player if the moving speed is larger than the speed reference value so as to turn up the volume of the audio player. The invention further provides a volume adjusting method.

Description

technical field [0001] The invention relates to a device and method for adjusting the volume of an audio player in a mobile device. Background technique [0002] At present, audio playback devices in mobile devices such as vehicles, such as televisions, mobile phones, and car DVDs, etc., are all manually adjusted by the user. Usually, the user manually adjusts the volume of the audio playback device according to the ambient noise. When the ambient noise is high, the user uses the remote control or operates the volume adjustment knob to increase the volume of the audio playback device; The volume of the device is turned down. [0003] However, when the magnitude of the ambient noise is constantly changing, the user needs to constantly perform manual adjustments, which brings inconvenience to the user. Contents of the invention [0004] In view of this, it is necessary to provide a device for volume adjustment based on ambient noise. [0005] It is also necessary to provi...
