Abstract
The present invention provides a speaker module for a mobile terminal provided with a sound output port. The speaker module includes a speaker box. The speaker box includes a first sound output opening and a second sound output opening. A speaker module also includes a first horn barrel and a second horn barrel. The first horn barrel and the second horn barrel are arranged asymmetrically with respect to the speaker box. The speaker module in the present invention realizes the multi-order coupling of the resonance peak, which not only improves the high-frequency performance, but also widens the frequency band range, and at the same time, reduces the manufacturing cost.
