摘要： This application discloses an audio playing method and a related apparatus. An electronic device includes one or more sound generation units, and the one or more sound generation units include one or more second-part side sound generation units and one or more first-part side sound generation units. When a sound effect mode of the electronic device is a first mode, the electronic device may receive an input for playing a specified audio, and in response to the input, process audio data (also referred to as audio source data) of the specified audio of the electronic device based on the first mode, to obtain audio data corresponding to a plurality of sound generation units of the electronic device. The plurality of sound generation units of the electronic device simultaneously play the corresponding audio data. In this way, the electronic device can cooperatively play a first audio by using the first-part side sound generation unit and the second-part side sound generation unit, to improve a surround feeling and an immersion feeling of a sound field of the electronic device, and enhance an audio playing effect.

摘要： Embodiments of this application disclose a speaker, a speaker module, and an electronic device. The speaker includes a support, a first diaphragm, a first piezoelectric plate, and a moving coil speaker core. Peripheral edges of the first diaphragm are fastened to the support, and the first piezoelectric plate is fastened to a middle part of the first diaphragm. The moving coil speaker core is fastened to the support and is spaced from the first diaphragm. The moving coil speaker core includes a second diaphragm. The second diaphragm is disposed facing the first diaphragm. The second diaphragm, the support, and the first diaphragm jointly enclose a front cavity. The support is provided with a speaker hole, and the speaker hole connects the front cavity and external space of the speaker. The first diaphragm and the second diaphragm of the speaker are disposed opposite each other and share the front cavity, to complement medium-frequency and high-frequency responses of the speaker and improve overall loudness of the speaker.

摘要： This application provides a speaker module, including: a first enclosure, a speaker core, and a waterproof breathable film. The first enclosure is provided with an accommodating groove, the speaker core is mounted on the accommodating groove, the speaker core includes a sound diaphragm, a front sound cavity is formed between the sound diaphragm and the first enclosure, and a rear sound cavity is on a side that is of the sound diaphragm and that is away from the front sound cavity. The first enclosure is further provided with a resonant groove, a bottom of the resonant groove is provided with a communicating hole, and the resonant groove communicates with the front sound cavity through the communicating hole. The waterproof breathable film covers an opening that is of the resonant groove and that faces the rear sound cavity, to isolate the resonant groove from the rear sound cavity, so as to balance atmospheric pressure of the front sound cavity and the rear sound cavity when the speaker module does not work, avoid a problem that sound diaphragm is shifted and sound quality of the speaker module is affected due to different atmospheric pressure of the front sound cavity and the rear sound cavity, and improve the sound quality of the speaker module. This application further provides an electronic device.
