Micro speaker module

Abstract

Disclosed is a micro speaker module capable of reducing the thickness of an enclosure that supports a micro speaker. The enclosure of the disclosed micro speaker module includes a first frame having a supporting portion configured to support the micro speaker, and a second frame configured to cover an open side of the first frame. A first cover and a second cover are respectively insert injection molded with or attached to portions of the first frame and the second frame corresponding to the micro speaker that is supported by the supporting portion, which results in a reduction in the thickness of each frame.

Description

technical field [0001] The present invention relates to a micro speaker module, and in more detail, relates to a micro speaker module capable of reducing the thickness of an enclosure supporting the micro speaker. Background technique [0002] Usually, portable electronic devices such as portable mobile communication terminal devices, notebook computers, MP3 players, etc. are equipped with micro speaker modules, which convert electrical signals into audio signals. [0003] The existing micro-speaker module includes: a micro-speaker; and a housing that supports the micro-speaker and is used to cut off the back sound so that the back sound emitted from the micro-speaker does not mix with the front sound. [0004] The casing includes: a first frame, which supports the micro-speaker, and forms a sound pipe for releasing the front sound of the micro-speaker; a second frame, which covers the open surface of the first frame, and is between the first frame and the first frame. A ba...

Problems solved by technology

[0006] However, since the first and second frames of the case are made of synthetic resin material and formed by injection molding, each frame has its own thickness, so the existing micro speaker module has limitations in reducing the thickness of the micro speaker module.

In particular, one side of the first frame should have a certain thickness for forming the sound outlet, so there is a limitation in reducing the thickness

[0007] In addition, the first frame of the existing miniature speaker module housing is formed with a locking part for installing and supporting the microspeaker. Due to the existence of this locking part, friction is increased when the microspeaker plays sound, resulting in a decrease in volume. The problem

[0008] In addition, the microspeaker of the existing microspeaker module is equipped with a gasket, which plays a close role when the microspeaker is supported by the locking part of the first frame, and due to the existence of this gasket, the thickness of the microspeaker module is reduced. limited
