Abstract

The invention discloses a mobile electronic equipment and an audio playing device thereof. The audio playing device comprises a first audio player and a second player which are respectively used for playing a left channel audio and a right channel audio, a first audio receiver and a second audio receiver which are respectively used for receiving a first echo of the left channel audio and a second echo of the right channel audio in real time, a control unit which is used for compensating the left channel audio and the right channel audio according to the received first echo and the received second echo and controlling the first audio player and the second audio player for respectively playing the left channel audio after compensation and the right channel audio after compensation, and the left channel audio after compensation and the right channel audio after compensation can respectively counteract the first echo and the second echo. The audio playing device compensates the left channel audio and the right channel audio through receiving the echoes generated by the left channel audio and the right channel audio, can avoid asymmetry between the left channel audio and the right channel audio and enables a listener to have an excellent stereo feeling effect.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a mobile electronic device and an audio playback device thereof. Background technique [0002] Mobile electronic devices (including tablet computers and mobile phones, etc.) have been widely used as audio players. And, the listener expects the audio played by the mobile electronic device to have a stereo effect. Stereo usually uses a pair of audio players to respectively play the left channel audio and the right channel audio corresponding to the left ear and the right ear to make the listener feel the stereo effect. [0003] However, the environment in which mobile electronic devices are used is generally complex, and listeners may listen to audio while moving, which will cause obvious asymmetry in the echoes generated by the left-channel audio and right-channel audio. Asymmetrical echoes cause an imbalance between left and right channel audio, resulting in a blurred stereo effect. ...
