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

Abstract

The invention provides a speaker box, including a rear cover, a front cover that encloses an accommodating space together with the rear cover, a sounding unit accommodated in the accommodating space,a sound guiding channel formed in the accommodating space, and a sealing layer, wherein the sounding unit is spaced apart from the front cover and encloses a front sound cavity together with the frontcover, and the sound guiding channel connects the front sound cavity to the outside and forms a front cavity together with the front sound cavity; the front cover includes a body part, a through holethat penetrates through the body part and is communicated with the front cavity, and a steel sheet that is completely covered on 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 annularly arranged on the periphery of the steel sheet and is sandwiched between the body part and the steel sheet. The invention also provides a manufacturing method of the above speaker box. Compared with the related art, the speaker box provided by the invention has excellent waterproof performance and good reliability.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a speaker box used in portable electronic products and a manufacturing method thereof. Background technique [0002] During the rapid development of portable devices such as mobile phones, people have increasingly strong requirements for product functionality. For speaker boxes, not only are they required to have good acoustic performance, but more and more requirements have been put forward for waterproof performance. [0003] The speaker box of the related art includes a front cover, a rear cover that is combined with the front cover to form a storage space, a sound unit accommodated in the storage space, and a sound channel formed in the sound unit. The body and the front cover form a front acoustic cavity, the sound unit, the rear cover and the front cover together form a rear cavity, the sound channel forms a front cavity with the front acoustic cavity and...
