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.

Abstract: The invention provides a speaker module for a mobile terminal with a sound output port. The speaker module includes a speaker box. The speaker box includes a sound output opening for side surface sound. The speaker module also includes a horn barre. The horn barrel has openings arranged at both ends. A sectional area along the sound output direction of the horn barrel changes gradually. By designing a variable sectional surface with different areas or lengths and widths on the horn barrel for stakeout, the size of the variable sectional surface is directly related to the sound quality of each part of the horn barrel. The horn barrel widens the frequency band range. Compared with the related art, the present invention can realize multi-level resonance, has a small volume, is convenient to widen the frequency band range and has flexible avoidance space.

Abstract: A sound reproducing apparatus is disclosed. The sound reproducing apparatus includes a signal processing unit, a first transducer, and a second transducer. The signal processing unit is configured to receive a sound signal and divide the sound signal into a first frequency component and a second frequency component. The first frequency component is at least partially different from the second frequency component, and the signal processing unit includes a delay unit configured to delay the second frequency band component. The first transducer is configured to convert the first frequency component from the signal processing unit into airborne sound. The second transducer is configured to convert the second frequency component from the delay unit into bone conduction sound.
