Abstract

The present invention relates to the field of sound film technology, in particular to an earpiece film and a preparation method thereof, comprising the following steps: step (A): overlapping, cutting, punching and cutting the middle original film and the surface original film to produce a casing film, the casing film includes: The middle frame group formed by the middle original film, and the surface frame group punched out by the surface original film; step (B): use the fan gate to fill out the original engineering film, and then stamp and cut it into small pieces to make the engineering film group; step (C) : Clean the middle frame group, surface frame group and engineering film group, coat the upper and lower surfaces of the middle frame group with powder and glue, then stick the surface frame group on the upper surface of the middle frame group, and finally stick the engineering film group on the The lower surface of the middle frame group is stamped and cut into several earpiece films. The preparation method of the earpiece film of the present invention is simple, can be mass-produced, and can prepare a micro-miniature earpiece film, and the prepared earpiece film has high elasticity, high toughness, good transient state, sensitivity, frequency response, and long-lasting good performance. 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...
