Abstract

The invention discloses an audio frequency device with a graphene composite sound film. The audio frequency device is provided with a vibration sound film, a shell frame, a drive circuit or a sensing circuit, wherein the shell frame defines a cavity in which the vibration sound film vibrates, and the drive circuit or the sensing circuit is used for driving the sound film to produce sound through vibration or sensing the vibration of the vibration sound film so as to output a signal. The vibration sound film of the audio frequency device is a composite sound film and is formed by compositing a fiber meshy graphene layer and a thin polymer film. By means of the graphene composite sound film, the thickness and quality of the composite sound film can be remarkably reduced, the acoustical frequency response characteristic of the sound film is improved, and the sensitivity and fidelity of the audio frequency device are improved. The audio frequency device is convenient to install, high in durability and reliability and low in manufacture cost, and tone quality and tone are greatly improved on the premise that high frequency response characteristic is kept.

Description

technical field [0001] The present invention relates to an audio device with a composite vibrating sound film, and more specifically, the present invention relates to an audio device with a graphene composite sound film. Background technique [0002] For audio devices that collect sound signals and play back sound signals through the vibration of the sound membrane, the mechanical properties of audio are crucial. There are a large number of existing technical solutions in the prior art. For example, a composite sound membrane structure is disclosed in the patent document CN 202679593U. This prior art adopts the structure of composite sound membrane formed by compounding sheet materials on an engineering film , and in order to overcome the manufacturing difficulties of the annular fixing structure of the composite sound membrane, a hot-pressed thin film fixing ring is added at the bottom of the sound membrane, but the composite sound membrane has the disadvantages of high qua...
