Abstract:
A loudspeaker module comprising a peripheral housing and a loudspeaker unit accommodated inside the peripheral housing, wherein the loudspeaker unit comprises a diaphragm sheet, a side wall of the peripheral housing is provided with a side sound hole of the loudspeaker module, a space formed by the diaphragm sheet, the peripheral housing and the side sound hole is a sound channel of a front acoustic cavity, the sound channel comprises a root portion close to the diaphragm sheet, an opening portion close to the side sound hole and side walls connecting the root portion and the opening portion and arranged oppositely, the side walls comprise a straight side wall and a bent side wall, and the width of the root portion of the sound channel is greater than the width of the opening portion. By means of the loudspeaker module in the present invention, sound waves may be transmitted more smoothly in the sound channel, and reflection and interference of the sound waves caused by the side walls of the sound channel are reduced, so that minimization of high order harmonic distortion can be effectively achieved, and the product tone quality is effectively improved.

Claim (Index 11):
The loudspeaker module of  claim 10 , wherein the housing comprises an upper housing and a lower housing cooperating with the upper housing; and the side sound hole is arranged on a side wall of the upper housing.
