Problems solved by technology

[0006] Also, because the adhesive is somewhat fluid and it takes time to harden the adhesive, it can be difficult to precisely bond the film in the desired position
Also, it takes time to wait for the fixation after
[0007] In addition, when heat and pressure are used to join desired portions of the film, since heat and pressure must be applied directly to the molding die, there may be deviations at the joining position
[0008] Furthermore, if several films are formed of different materials and bonded taking into account the acoustic characteristics of the speaker, some of the materials of the films may chemically react with the adhesive

Embodiment Construction

[0029] Reference will now be made to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0030] figure 1 is a perspective view of a diaphragm of a micro horn according to an embodiment of the present invention, figure 2 for adoption figure 1 Cutaway view of the microhorn of the diaphragm, and image 3 for figure 1 A cross-sectional view of the diaphragm.

[0031] Diaphragm 1 is a micro-speaker device for a small audio device, such as a mobile phone, a notebook computer, an MP3 player, an earphone, and the like. The diaphragm 1 includes several thin films formed of a polymer compound and stacked on top of each other.

[0032] Due to the predominantly small size of the diaphragm 1 of the microhorn, the membranes have different shapes and are formed from different materials in order to achieve the desired sound characteristics. Although the diaphragm may be formed of a single thin film. In this embodiment, however,...

Abstract

The present invention provides a diaphragm for a microspeaker, and a method of manufacturing the diaphragm. The diaphragm includes several thin film-shaped members made of polymer compounds and laminated mutually, wherein the thin films are engaged by ultrasonic welding program. The method includes preparing a mould, placing a first part on the mould to obtain a first part of the member in a required shape, placing a second part on the first part of the required shape, and welding the first part and the second part by the ultrasonic welding program.

Description

technical field [0001] The present invention relates to a diaphragm (diaphragm) of a micro-speaker, and a method for manufacturing the diaphragm, in particular to a diaphragm formed by several thin films, and a method for manufacturing the diaphragm, which can be used in a desired Seam the film together precisely at the desired location. Background technique [0002] In a nutshell, a speaker is a sound device that converts electrical signals into sound signals. Speakers can be classified into medium / large speakers, which are connected to stereos or amplifiers to greatly amplify the sound, and miniature speakers, which are mainly used in portable sound devices such as mobile phones, laptops, MP3 players, headphones, etc. [0003] The diaphragm of a typical microhorn must be of small size. Therefore, a flexible and lightweight membrane diaphragm is used to enhance its efficiency. However, since the membrane type diaphragm is smaller than that of a medium / large speaker, it i...
