Description

technical field

[0001] The present disclosure relates to the technical field of communication, and in particular to an audio output module, method and terminal equipment. Background technique

[0002] With the development of electronic communication technology, users have higher and higher requirements for the audio-visual experience of terminal devices such as mobile phones and tablet devices, and require better sound quality and higher output volume. However, terminal devices in related technologies are generally only equipped with A single speaker cannot meet the above-mentioned sound effect requirements.

[0003] In order to solve the above problems, the related technologies generally adopt adding a speaker in the terminal equipment to output audio signals, and the above speaker is generally a traditional dynamic speaker. However, due to the complex structure of the existing speakers, and the consideration of sound effects, the two speakers need to be separated and set ...
