Disclosed in embodiments of the present disclosure are a diaphragm assembly, a loudspeaker module and an electronic device, the diaphragm assembly including a diaphragm body and an intermediate patch plate, wherein the diaphragm body includes a first diaphragm body and a second diaphragm body; the first diaphragm body is provided with a first hole; the intermediate patch plate includes a first intermediate patch plate; the second diaphragm body at least partially cover the first hole; the first intermediate patch plate is respectively connected to the first diaphragm body and the second diaphragm body; the first intermediate patch plate is configured to have an enclosed structure, or the intermediate patch plate includes a second intermediate patch plate connected to the second diaphragm body, such that the mid-high frequency curves of the loudspeaker module are smoother, thereby effectively improving the mid-high frequency tone quality.

Diaphragm assembly and loudspeaker module

The present disclosure provides a speaker which includes a case component, a vibration plate, a driving component, a first adjustment unit, and a second adjustment unit. The case component has an accommodating space and a sound outlet channel. The accommodating space communicates with the sound outlet channel. The vibration plate is disposed in the accommodating space. The driving component is disposed in the accommodating space and configured to drive the vibration plate to vibrate. The first adjustment unit is disposed in the sound outlet channel, and the first adjustment unit is constituted of acoustic metamaterials. The second adjustment unit is disposed on one side of the vibration plate, and the second adjustment unit is constituted of acoustic metamaterials.

Speaker

A speaker module includes a first cavity body, a second cavity body disposed adjacent to the first cavity body and a vibration module disposed in the first cavity body and including a first diaphragm and a second diaphragm which are horizontally spaced apart. The first cavity body includes a first sub-cavity and a second sub-cavity which are respectively located on two opposite sides of the vibration module, and the second sub-cavity is communicated with the second cavity body.

Speaker module

The invention provides a speaker, an audio device thereof, and a method of regulating frequency response. The speaker comprises a back cavity and a magnetic circuit system connected to the back cavity, and further comprises: an intermediate-frequency frequency response regulation module disposed in the back cavity for regulating a length of a first effective air passage of the back cavity where an air flow passes, such that a resonant frequency of the back cavity is equivalent to a frequency of intermediate-frequency frequency response of the speaker to be improved; and/or a high-frequency frequency response regulation module disposed in the back cavity for regulating a length of a second effective air passage of the back cavity where the air flow passes, such that the resonant frequency of the back cavity is equivalent to a frequency of high-frequency frequency response of the speaker to be improved.
