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.

Implementation of the utility model

The present utility model will be further explained below in conjunction with the drawings and the embodiments.

Refer to Figure 1 and Figure 2, which is a speaker box provided by an embodiment of the present invention. The speaker box includes a cover body 2 enclosing a housing space 1 and a speaker unit 3 housed in the housing space 1. The cover body 2 is provided with a supporting step 20 extending toward the housing space 1. Specifically, the cover body 2 includes The front cover 21 and the rear cover 22 opposite to the front cover 21 form the accommodating space 1, and the supporting step 20 is formed on the front cover 21.

Referring to FIGS. 3 to 5, the supporting step 20 includes a step plane 201 supporting the speaker unit 3 and a side surface of the step that is bent and extended from the edge of the step plane 201 away from the speaker unit 3 to form a step spaced apart from the speaker unit 3. 202, the speaker unit 3 includes an end surface 31 abutting the step plane 201 and a side wall 32 opposite to the step side surface 202 and forming a gap 203; the step plane 201 is recessed away from the end surface 31 to form a plurality of exhaust grooves communicating with the gap 203 204, the end surface 31 of the speaker partially covers the exhaust groove 204. The above-mentioned supporting step 20 further includes a fixing table 205 arranged between two adjacent exhaust grooves 204, and the speaker unit 3 is fixed to the fixing table 205 through the end surface 31 to enhance the fixing of the speaker unit 3.

When the step side surface 202 on the support step 20 is glued and fixed with the side wall 32 of the speaker unit 3, the glue flows into the exhaust groove 204 through the gap 203 between the step side surface 202 and the side wall 32 to prevent glue overflow and promote The air between the step side 202 and the side wall 32 can enter the exhaust groove 204 from the gap 203 and be discharged without forming bubbles on the step side 202 and the side wall 32, ensuring the sealing of the step side 202 and the side wall 32. , The speaker unit 3 and the front cover 21 are glued firmly.

As shown in FIG. 6, the above-mentioned supporting step 20 has an annular structure, and a plurality of exhaust grooves 204 are arranged at intervals along the circumferential direction of the supporting step 20 to effectively and fully remove the air between the side surface 202 of the step and the side wall 32 from the exhaust groove 204 discharged. The step plane 201 and the step side surface 202 are perpendicular to each other, so that the glue can quickly fill the gap 203 between the step side surface 202 and the side wall 32. The step plane 201 and the end surface 31 are parallel to each other, so that the speaker unit 3 and the front cover 21 are in close contact.
