Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0038] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second" and so on...

Abstract

The invention discloses a vibrating membrane, a sounding device and an electronic device. The vibrating membrane comprises a first metal layer, a foam material layer and a second metal layer, wherein the foam material layer is arranged on the first metal layer , the second metal layer is arranged on the foam material layer, and the foam material layer is provided with a missing part opposite to the first metal layer, and the second metal layer is connected to the missing material The position corresponding to the part is recessed and then connected with the first metal layer. When the diaphragm of the present invention is applied to a sound generating device or an electronic device, the heat in the sound generating device or the electronic device can be dissipated in time, the temperature rise can be reduced, and the acoustic performance of the sound generating device and the electronic device can be improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a diaphragm, a sound generating device and an electronic device. Background technique [0002] With the development of mobile phone technology, users' demand for mobile phone experience has increased. At present, the application of smartPA (smart power amplifier) ​​technology in most mobile phones has become the mainstream. Currently, Smart PA mainly has two modules of temperature protection and amplitude protection, which mainly limit the power of the speaker according to one of temperature or amplitude. [0003] Applying the Smart PA technology to the speaker, the temperature resistance of each component of the speaker is limited. In order to prevent the speaker from being burned out by high temperature, the temperature protection module will limit the temperature of the speaker. At present, in order to increase the loudness of the speaker in some technologies...
