Electronic equipment and audio output control method thereof

Abstract

Electronic equipment comprises a storage unit, an audio output port, an impedance detecting unit, a digital and analog converter, an audio gain module and a processing unit. The impedance detecting unit detects an impedance value of an audio output device connected to the audio output port externally. The digital and analog converter is used for converting an audio file into an analog signal. The storage unit is used for storing an audio output mode relation table. The processing unit is used for determining a range of the detected impedance value, determining a corresponding audio output mode, and controlling the electronic equipment in the audio output mode. The audio gain module corresponds to different gain values when in different audio output modes, and amplifies the analog signal according to the gain value corresponding to the current audio output mode and then outputs the amplified signal. The invention further provides an audio output control method. The electronic equipment and the audio output control method have the advantages that the electronic equipment has good sound playing effect, and the problem of sound distortion caused by mismatching between audio output and audio output devices is avoided.

Description

technical field [0001] The invention relates to an electronic device and an audio output control method thereof. Background technique [0002] Electronic devices with audio output functions are increasingly favored by consumers. Usually, when consumers listen to music or enjoy audio-visual files through electronic devices, they connect to the audio output terminals of electronic devices through audio output devices such as headphones and speakers of different power. Instead, the audio message is played. Existing electronic equipment generally presets an audio output mode. For example, a music player usually presets an audio output mode corresponding to the earphone, and different audio output devices will match different impedances. When the electronic equipment presets When the audio output method does not match the audio output device connected to the electronic device, it is easy to cause serious output sound distortion. Contents of the invention [0003] In view of t...
