The invention relates to the technical field of communication, provides an audio playing device, an audio playing method and electronic equipment, and aims to solve the problem of mutual interferencewhen a two-in-one loudspeaker and a radio frequency module work at the same time. The audio playing device comprises a power amplifier module; a switch, wherein the input end of the switch is connected with the power amplifier module; a first noise suppression assembly and a second noise suppression assembly, wherein the first noise suppression assembly is connected with the first output end of the switch, and the second noise suppression assembly is connected with the second output end of the switch; a loudspeaker module which is connected with the first noise suppression assembly and the second noise suppression assembly. Under the condition that the loudspeaker module is in a receiver mode and a loudspeaker mode respectively, the input end of the switch is connected with the first output end and the second output end of the switch respectively. Thus, when the loudspeaker module is in different working modes, the loudspeaker module can be connected with different noise suppression assemblies through the switch, and mutual interference between the loudspeaker module and the radio frequency module in different working modes is avoided.
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...
