Telephone receiver film and preparation method thereof

Abstract

The invention relates to the technical field of voice film, and specifically relates to telephone receiver film and a preparation method thereof. The method comprises the steps of A, overlapping, cutting, punching and clipping intermediate original film and surface original film, thereby preparing sleeve film, wherein the sleeve film comprises an intermediate frame group formed by the intermediate original film, and a surface frame group punched from the surface original film; B, preparing engineering original film by filling through a fan gate, and punching and clipping the engineering original film, thereby preparing engineering film group; and C, washing the intermediate frame group, the surface frame group and the engineering film group, bepowdering and cementing the upper surface and lower surface of the intermediate frame group, adhering the surface frame group on the upper surface of the intermediate frame group, adhering the engineering film group on the lower surface of the surface frame group, and carrying out punching and clipping to prepare a plurality of pieces of telephone receiver film. The preparation method of the telephone receiver film is simple; mass production can be realized; the miniature telephone receiver film can be prepared; and the prepared telephone receiver film has high elasticity, high toughness, good transient state, high sensitivity, high frequency response and everlasting good sound quality.

Description

technical field [0001] The invention relates to the technical field of sound film, in particular to an earpiece film and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for a series of audio facilities such as earphones and speakers are getting higher and higher, especially for mobile phones and in-ear earplug speakers. The development trend is to have better and better sound effects and more and more Smaller sound generators. As one of the key components of the sound generator, the thin film has a vital impact on the sound quality of the speaker, and it is more difficult to prepare a small earpiece thin film. Therefore, the design of small earpiece thin films has always been one of the important topics of continuous innovation in the industry. [0003] The objective indicators such as the frequency response curve of the speaker are mainly determined by the geometry of the film, while the subjec...

Problems solved by technology

[0004] Among them, paper films have been around for a long time and are widely used in some speakers. However, due to the shortcomings of paper films, which are easy to be affected by moisture, the sound quality is unstable, and they are gradually replaced by other films.

Plastic film has the advantages of low cost, good plasticity, and easy processing, but the rigidity of plastic film is poor, which seriously affects the sound quality of the speaker

However, no matter paper material or plastic material, due to material reasons, it is impossible to achieve ultra-thin thickness, and the structure of the setting is unreasonable, so it is impossible to produce the best sound quality of the sound film material.
