Abstract

The invention relates to the field of communication technology, and provides an audio playing device, an audio playing method and electronic equipment, so as to solve the problem of mutual interference when a two-in-one speaker and a radio frequency module work simultaneously. The audio playback device includes: a power amplifier module; a switch, the input end of the switch is connected to the power amplifier module; a first noise suppression component and a second noise suppression component, the first noise suppression component is connected to the first output end of the switch, and the second noise suppression component Connect with the second output end of switch; Loudspeaker module, connect the first noise suppressing component and the second noise suppressing component; terminal is connected to the second output terminal. In this way, when the speaker module is in different working modes, it can be connected to different noise suppression components through the switch, so as to avoid mutual interference between the speaker module and the radio frequency module in different working modes.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an audio playing device, an audio playing method and electronic equipment. Background technique [0002] With the development of multimedia technology, electronic devices are equipped with dual speakers, which can not only increase the volume, but also form a stereo sound field by using the dual speakers to play audio. [0003] In the prior art, dual speakers need to be equipped with two intelligent power amplifiers, one for driving traditional speakers and one for driving 2-in-1 speakers. Wherein, the two-in-one speaker includes two working modes: a speaker mode and a receiver mode. When the 2-in-1 speaker is in the speaker mode, the required volume is high, the output voltage of the smart power amplifier corresponding to the 2-in-1 speaker is high, and the current on the path is relatively large; when the 2-in-1 speaker is in the receiver mode, there is no need t...
