Loudspeaker box and method of making the same

Abstract

The present invention provides a loudspeaker box, comprising a rear cover, a front cover which together with the rear cover encloses a storage space, a sound emitting unit stored in the storage space, a sound guiding channel formed in the storage space and a sealing layer; the sound-emitting unit and the front cover are arranged at intervals and jointly form a front acoustic cavity, and the sound guide channel communicates the front acoustic cavity with the outside world and jointly forms a front cavity; the front cover includes a body part, runs through the The through hole communicating with the front cavity of the body part and the steel sheet completely covering the through hole and fixed to the body part; the sealing layer is fixedly arranged on the steel sheet, and the sealing layer is at least ring It is arranged on the periphery of the steel sheet and sandwiched between the main body and the steel sheet. The present invention also provides a manufacturing method of the speaker box. Compared with related technologies, the speaker box of the invention has excellent waterproof performance and good reliability.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic conversion, in particular to a speaker box used in portable electronic products and a manufacturing method thereof. Background technique [0002] In the process of rapid development of portable devices such as mobile phones, people have increasingly strong functional requirements for products. For speaker boxes, not only are they required to have good acoustic performance, but more and more requirements are also put forward for waterproof performance. [0003] The speaker box of the related art includes a front cover, a rear cover assembled with the front cover to form a receiving space, a sounding unit housed in the receiving space, and a sound outlet channel formed in the sounding unit. The body and the front cover enclose a front acoustic cavity, the sound-emitting unit, the rear cover and the front cover together form a rear cavity, and the sound outlet channel and the front acoustic ...

AI Technical Summary

Problems solved by technology

[0004] However, in order to improve the acoustic performance, the front cover includes a through hole that runs through it and is opposite to the sound unit and a steel sheet that is completely covered and fixed on the through hole. The steel sheet and the front cover are injection molded, and then the edges of the steel sheet and the front cover are sealed by dispensing glue to ensure waterproof performance. However, when the glue is dispensed on the outside of the front cover, it will affect the appearance. When dispensing glue on the inner side of the front cover, the dispensing takes up a lot of space and the consistency is not good, making the waterproof performance unstable
