WIPO Patent Application WO/2024/016400
Kind Code:
A1
Abstract:
A loudspeaker module, used for a mobile terminal provided with a sound outlet. The loudspeaker module comprises a loudspeaker box, the loudspeaker box comprising a first sound output opening and a second sound output opening. The loudspeaker module further comprises a first horn and a second horn. One end of the first horn is connected to a side surface of the loudspeaker box and communicated with the first sound output opening, and the other end of the first horn is used for connecting to a sound outlet of a mobile terminal. One end of the second horn is connected to a side face of the loudspeaker box and communicated with the second sound output opening, and the other end of the second horn is used for connecting to the sound outlet of the mobile terminal. The first horn and the second horn are asymmetrically arranged with respect to the loudspeaker box. The loudspeaker module achieves multi-order coupling of resonance peaks, thus not only improving the high-frequency performance, but also expanding the frequency band range, and meanwhile reduces manufacturing costs.
