[0044] Example one

[0045] Reference Figures 1 to 3The embodiment provides a loudspeaker module, which comprises a module shell 1, a first damping part 2, a first loudspeaker 3 and a first sound outlet pipe 5. The module shell 1 is provided with a front cavity 11. The first damping part 2 is arranged on the end surface of the module shell 1 facing the front cavity 11. The first loudspeaker 3 is arranged on the first damping part 2 and corresponds to the front cavity 11. A second loudspeaker 4 is arranged on the module shell 1. The sound outlet 41 of the second loudspeaker 4 is connected to the outer surface of the module shell 1 and communicates with the second sound outlet pipe 121 of the module shell 1. The first sound outlet pipe 5 is arranged in the module shell 1. One end of the first sound outlet pipe 5 communicates with the front cavity 11, and the other end of the first sound outlet pipe 5 communicates with the surface of the module shell 1 away from the front cavity 11, for example, the side surface of the module shell 1 or the surface away from the front cavity 11. The first loudspeaker 3 and the second loudspeaker 4 in the embodiment are loudspeakers each comprising a shell, a magnetic circuit assembly, a voice coil and a diaphragm. In some embodiments, the first loudspeaker 3 is a bass loudspeaker, and the second loudspeaker 4 is a treble loudspeaker. In some embodiments, the first sound outlet pipe 5 can be a filter pipe, which can filter the unwanted audio frequency band to produce the effect of low-pass filtering or high-pass filtering. When the audio electrical signal drives the first loudspeaker 3 and the second loudspeaker 4 through the electrical signal connecting wire 100, the first loudspeaker 3 can mainly produce low-frequency or low-mid-frequency sound, but the first loudspeaker 3 can still produce unwanted or additional mid-high-frequency sound, which is filtered out through the first sound outlet pipe 5 and output as low-frequency sound. The second loudspeaker 4 can produce high-frequency sound, and then the low-frequency sound and the high-frequency sound are coupled to emit a sound with a wider frequency band.

[0046] The loudspeaker module of the embodiment can arrange the first loudspeaker 3 and the second loudspeaker 4 on the module shell 1. The front cavity 11 and the first sound outlet pipe 5 are arranged on the module shell 1, so that the first loudspeaker 3 arranged on the module shell 1 can filter out the unwanted audio frequency band through the first sound outlet pipe 5 to produce the effect of low-pass filtering or high-pass filtering when the first loudspeaker 3 works. The second loudspeaker 4 transmits audio to the outside of the module shell 1 through the sound outlet 41. In addition, the first damping part 2 arranged on the module shell 1 can play a damping effect on the first loudspeaker 3, so as to avoid the loudspeaker module from being damaged when the electronic device falls or is impacted. The loudspeaker module of the embodiment integrates the front cavity 11, the first loudspeaker 3, the second loudspeaker 4, the first damping part 2 and the first sound outlet pipe 5 on the module shell 1, which effectively simplifies the complicated process of assembling the loudspeaker module in the electronic device later, is beneficial to improving the product yield and processing efficiency and reducing the production cost.
