Problems solved by technology

[0007] Therefore, none of the existing diaphragms can have or come close to the high-frequency sound quality performance of the metal diaphragm and the low-frequency sound quality performance of graphene.
The existing technology uses the splicing of various diaphragms of different materials or the combination of sound-generating components of diaphragms of different materials to achieve high-frequency sound quality and low-frequency sound quality. This design increases the difficulty of combining coils and diaphragms or sound source processing. In addition , the existing diaphragms of different materials still face poor rigidity, high density, poor heat dissipation, complicated production, high cost and other problems

Abstract

The invention relates to a vibrating diaphragm, a sound production device and a microphone assembly, the vibrating diaphragm is applied to acoustoelectric interchange, and the vibrating diaphragm comprises a base material layer which is graphene or multilayer graphene; and the metal coating is compounded on the base material layer. The metal coating is made of one metal or at least two metals. The invention provides a vibrating diaphragm with excellent high-frequency, intermediate-frequency and low-frequency sound quality, which is high in rigidity, low in density, good in heat dissipation performance, low in Poisson's ratio, good in internal sound velocity, simple to manufacture and low in price.

Description

[0001] This application is a divisional application of a patent application entitled "Diaphragm, Sound-generating Device, Microphone Assembly, and Method for Making a Diaphragm". The application date of the original application is June 8, 2020, and the application number is 202010515756.5. technical field [0002] The present invention relates to the technical field of acousto-electrical interchange, in particular to a vibrating membrane, a sounding device and a microphone assembly. Background technique [0003] Sound-emitting devices such as speakers and earphones realize the conversion of electrical energy to sound energy, and microphones realize the conversion of sound energy to electrical energy. Among them, the diaphragm is the key component of the electro-acoustic converter / acoustic-electric converter, for example, the earphone uses the coil to drive the diaphragm to vibrate to generate sound. [0004] There are many types of diaphragms, including paper diaphragms, woo...
