Problems solved by technology

[0004] However, in the drop reliability test of the speaker module with this structure, the bonding strength between the separation sound hole and the module shell is not enough to overcome the bending moment during the drop impact, and the separation sound hole will fall off from the module shell, thus making the reliability test failed

Embodiment Construction

[0019] In order to illustrate the present invention more clearly, the present invention will be further described below with reference to the preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0020] like figure 1 As shown, the present invention provides a speaker module, the module includes a module housing and a speaker unit, an accommodation space is formed in the module housing, the speaker unit is accommodated in the accommodation space, and the accommodation The space is divided into front and rear acoustic chambers. The speaker unit is a moving coil unit or a moving iron unit. For ease of description, a moving coil unit is taken as an example in this embodiment. The moving coil monomer includes a vib...

Abstract

Disclosed is a speaker module, comprising a module housing forming an accommodating space, and a speaker body arranged in the accommodation space; the speaker body divides the accommodation space into a front acoustic cavity and a rear acoustic cavity; the module housing is provided with a sound output hole in communication with the front acoustic cavity; a fixed part is fixedly coupled to the outer surface of the module housing near the sound output hole; the speaker module also comprises a ring-shaped separate sound hole; the surface of the side of the separate sound hole near the module housing protrudes outward to form a plug-connection part; the plug-connection part has a shape corresponding to the inside surface of the sound hole; the plug-connection part and the sound output hole are arranged as an interference fit, and the separate sound hole is fixedly coupled to the surface of the fixed part. The structure is such that during a drop test, the bending force generated by the separate sound hole is borne by the housing, reducing the separation force between the separate sound hole and the fixed part; thus it is not easy to generate cracks between the separate sound hole and the housing and cause the separate sound hole to fall off the housing; thus the reliability of the present product is increased.

Description

technical field [0001] The invention relates to the field of electroacoustic technology. More specifically, it relates to a speaker module. Background technique [0002] The speaker module usually has a sound hole on the module casing, and the sound from the diaphragm is transmitted to the outside through the sound hole. In order to ensure the tightness of the speaker module and the whole machine after assembly, a sealing ring is generally pasted around the sound hole, and the material of the sealing ring is mostly silicone rubber. However, in the process of pasting the sealing ring, it is not easy to locate the sealing ring, and the sealing ring is easy to stick to the wrong position, which will block a part of the sound hole, resulting in poor consistency of the whole machine, affecting the acoustic effect of the whole machine and poor sealing. [0003] At present, there is a speaker module that injects silicone rubber onto the sound hole of the module shell to form a se...
