Description

Technical Field

[0001] This utility model relates to the field of electronic device structure technology, and in particular to a speaker. Background Technology

[0002] A speaker is a device that converts audio signals into sound. The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system, responsible for converting electrical signals into sound signals for people to hear directly. A wire mesh is often installed on the outer shell of the speaker to cover the sound hole and protect the speaker at the sound hole.

[0003] However, wire mesh is usually glued to the outer shell. This process requires a long time to prepare the pre-production steps. Especially for larger products and mass production, a large production and placement space is needed. In addition, the wire mesh is prone to stress deformation during the glue application and solidification process, which can easily cause it to move and result in the wire mesh not being assembled into the required position after the glue has solidified.

[0033] Please see Figures 1 to 7 As shown in the figure, this utility model embodiment discloses a speaker, mainly used as a secondary speaker. The speaker includes a support frame 10, a speaker 20, a grille 30, and a cover 40. The speaker 20 is mounted on the support frame 10. The grille 30 is provided with a retaining cavity 31. The grille 30 includes a cover body 32 and a plurality of limiting blocks 33. Each limiting block 33 is vertically disposed on each edge of the cover body 32. The cover body 32 and each limiting block 33 together enclose the retaining cavity 31. The grille 30 can be made of iron mesh material.

[0034] The cover 40 is provided with a sound hole 41. The cover 40 includes a panel 42 and a protrusion 43 protruding from the inner wall of the panel 42. The cross-section of the cover 32 and the panel 42 is U-shaped. The sound hole 41 passes through the protrusion 43 and the panel 42 in sequence. The panel 42 can be snapped into the holding cavity 31 by a jig to limit the front-back, up-down and left-right directions of the panel 42, resulting in a combination of the large-bellied mesh cover 30 and the cover 40. The protrusion 43 is connected to the support frame 10 and covers the speaker 20. The sound hole 41 is set correspondingly to the speaker 20.
