Abstract

A speaker sounding hole device includes a speaker single-unit front cover and a module housing. The speaker single-unit front cover is rectangular, the long edges and/or short edges of the speaker single-unit front cover are provided with open grooves, and the speaker single-unit front cover and the module housing are correspondingly assembled by means of the open grooves. The speaker single-unit front cover provided with the open grooves and the module housing form a front cavity of the speaker sounding hole device. Spaces formed by the open grooves are connected with the front cavity of the speaker sounding hole device to form a sounding channel of the speaker sounding hole device. The device can solve the problems of high cost, long tuning time of the product performance, poor sounding effects and low product efficiency.

First claim

The invention claimed is:

1. A speaker sound hole device, comprising:
a front cover of a speaker unit and a module housing, wherein the front cover of the speaker unit is in a rectangular shape, and at least one open groove is provided at a long side and a short side of the front cover of the speaker unit,
the front cover of the speaker unit is correspondingly assembled with the module housing through the open groove,
a front cavity of the speaker sound hole device is formed by the front cover of the speaker unit, which is provided with the open groove, and the module housing, and
a sound channel of the speaker sound hole device is formed by a space defined by the open groove together with the front cavity of the speaker sound hole device.

2. The speaker sound hole device according to claim 1 , wherein two or four open grooves are provided at the long side and the short side of the front cover of the speaker unit.

3. The speaker sound hole device according to claim 1 , wherein the front cover of the speaker unit is provided with mounting direction holes for the speaker unit.

4. The speaker sound hole device according to claim 3 , wherein the number of the mounting direction holes for the speaker unit is one or two.

5. The speaker sound hole device according to claim 1 , wherein a gap of the sound channel of the speaker sound hole device is a sum of a distance from a top to a bottom of the open groove and a distance from the front cover of the speaker unit to the module housing.

6. The speaker sound hole device according to claim 5 , wherein the gap of the sound channel is about 0.76 mm.
