Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Please also refer to Figure 1-3 As shown, the present invention provides a speaker box 100 , including an upper cover 1 , a lower cover 2 , a sound emitting unit 3 , a sound guiding channel 4 and a welding rib 5 .

[0022] The lower cover 2 is closed to the upper cover 1 and jointly encloses a receiving space 10 . The upper cover 1 and the lower cover 2 can be of an integral structure, or can be of a separate structure.

[0023] The upper cover 1 protrudes and extends to form a supporting wall 11 for supporting the sounding unit 3 .

[0024] In this embodiment, the support wall 11 is formed by extending the upper cover 1 toward the lower cover 2 , and the support wall 11 has a ring-shaped structure.

[0025] The sound emitting unit 3 is accommodated and fixed in the accommodation space 10 , and divides the accommodation space 10 into a front ...

Abstract

The invention provides a loudspeaker box comprising a lower cover, an upper cover that collectively forms an accommodating space together with the lower cover, a sounding unit accommodated in the accommodating space, a sound conducting channel formed in the accommodating space, and a welding rib, wherein the upper cover protrudes and extends to form a supporting wall, the sounding unit is supported on the supporting wall and is spaced from the upper cover to form a front sound cavity, and the sound guiding channel communicates the front sound cavity with the outside to form a front cavity; thewelding rib is formed by extending the peripheral edge of the sounding unit toward the supporting wall, the welding rib abuts against the supporting wall and is fixedly welded with the supporting wall through an ultrasonic welding process. Compared with the related art, the loudspeaker box provided by the invention has the advantages of good waterproof performance, excellent acoustic performanceand high assembly efficiency.

Description

technical field [0001] The invention relates to a speaker box, in particular to a speaker box used in portable electronic products. 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 an upper cover, a lower cover which is combined with the upper cover to form a storage space, a sound unit accommodated in the storage space and a sound channel formed in the storage space, the sound unit The body and the upper cover form a front acoustic cavity, the sound emitting unit, the lower cover and the upper cover together form a rear cavity, the sound channel and the front acoustic cavity form a front cavity and connect the front cavity The vocal cavity...
