Loudspeaker module and manufacturing method thereof

Abstract

The invention relates to the electroacoustic technical field, and provides a loudspeaker module and a manufacturing method thereof. The loudspeaker module comprises a case and a single loudspeaker body combined inside the case. The single loudspeaker body comprises a vibrating diaphragm assembly and a magnetic circuit assembly. A front sound cavity and a rear sound cavity are formed between the single loudspeaker body and the case. The case is provided with an elastic part, the elastic part is combined with the end surface of the opening end of the front sound cavity or the rear sound cavity, and the elastic part and the case are of an integrated structure formed in an injection molding mode. By adopting the structure in the loudspeaker module, the process of attaching the elastic part manually is eliminated, the accuracy and the stability of combination of the elastic part are guaranteed, the elastic part does not fall easily, the sealing property between a sound outlet hole of the loudspeaker module and a sound hole of a mobile phone after the loudspeaker module and a terminal electronic product are assembled can be effectively guaranteed, and the acoustic performance is improved. The manufacturing method for the loudspeaker module can solve the technical problems effectively and can be popularized to production for other structures with soft materials or hard materials needing to be injected into other materials.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a loudspeaker module and a manufacturing method thereof. Background technique [0002] The speaker module is an important acoustic component in portable electronic equipment, which is used to convert electrical energy into sound energy, and is the sound-generating component of portable electronic equipment. In the prior art, a speaker module generally includes a housing and a speaker unit housed inside the housing. The speaker unit includes a diaphragm assembly and a magnetic circuit assembly. The speaker module is provided with a front acoustic cavity and a rear acoustic cavity. The side of the housing facing the diaphragm assembly is jointly surrounded by the diaphragm assembly, and the rear acoustic cavity is jointly enclosed by the side of the housing away from the front acoustic cavity and the diaphragm assembly; for speaker modules that emit sound from the front, t...

AI Technical Summary

Problems solved by technology

[0004] This design requires the shape of the elastic member to be regular, but the shape and structure of the junction between different terminal electronic products and speaker modules are different, and the shape of the junction is irregular and the structure is complex, making it suitable for The matching elastic parts also have the characteristics of irregular shape and complex structure. Due to the soft hardness and complex shape of the elastic parts, it is not easy to shape and control; and when the elastic parts with complex shapes are manually attached, the high precision is required, resulting in low labor efficiency and low quality. Hidden danger

Sometimes due to the special assembly method requirements of the client, the artificially bonded elastic parts are easy to fall off during assembly, which cannot meet the customer's requirements
