Title:
SPEAKER BOX
Document Type and Number:
WIPO Patent Application WO/2021/000099
Kind Code:
A1
Abstract:
The present invention relates to the technical field of sound emission devices. Provided is a speaker box. The speaker comprises a cover body enclosing an accommodation space and a speaker unit accommodated inside the accommodation space. The cover body is provided with a supporting step extending toward the interior of the accommodation space. The supporting step comprises a step flat surface supporting the speaker unit and a step side surface bending and extending from an edge of the step flat surface away from the speaker unit and spaced apart from the speaker unit. The speaker unit comprises an end surface abutting the step flat surface and a sidewall opposite to the step side surface. A gap is formed between the sidewall and the step side surface. The step flat surface has a plurality of air discharge recesses recessed in a direction away from the end surface and in communication with the gap. In the speaker box of the present invention, air discharge recesses are arranged at a step flat surface. When a step side surface and a sidewall are fixedly bonded together, an adhesive flows into the air discharge recesses from a gap between the step side surface and the sidewall, such that air in the gap is discharged from the air discharge recesses, thereby realizing favorable sealing between the step side surface and the sidewall, and ensuring bonding stability between a cover body and a speaker unit.
