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.
