Besides the common meeting and conversation functions, the microphone device can also be used for listening to music, watching video or playing games, and the like, so that the built-in loudspeaker of the microphone device is required to have rich bass effects, the music playing strength is improved, and the user experience is improved.

The built-in speaker of the existing microphone and the like usually forms a rear cavity of the speaker by means of a device housing, so that the speaker has a bass effect. However, the low frequency characteristic of the speaker generates strong resonance, and vibration is directly transmitted to the device housing, so that serious distortion problem is caused, which affects the audio effect of the microphone device in meeting and talking; and, assembly errors in assembling the speaker may also affect the consistency of the audio.

In order to solve the above problems, as shown in fig. 1 to 6, the present invention firstly provides a speaker assembly capable of avoiding distortion problems and improving consistency of audio.

As described above, the existing speaker forms a rear cavity of the speaker by means of the device housing, and vibration generated from the speaker is directly transmitted to the device housing, thereby causing serious distortion problems, and assembly errors may also affect the consistency of audio. In the speaker assembly provided by the embodiment of the invention, the speaker body 3 and the independent speaker housing 2 can form a speaker rear cavity, so that the speaker assembly has a bass effect, and the speaker body 3 and the speaker housing 2 can move relative to the first housing 1 when vibrating so as to counteract the shaking amount generated by the vibration, thereby avoiding the vibration from being transmitted to the first housing 1 and distortion; meanwhile, when the loudspeaker assembly is produced, the loudspeaker body 3 and the loudspeaker shell 2 can be used as a whole for processing and testing, the audio characteristics of the whole working process are evaluated, the modularization of the loudspeaker assembly is realized, the problem that noise and other bad problems are generated due to the assembly error between the loudspeaker body 3 and the loudspeaker shell 2 caused by the independent testing of the loudspeaker body 3 is avoided, the consistency of audio is affected, and therefore the audio effect of the loudspeaker assembly can be ensured.

As shown in fig. 1 to 2, in the illustrated embodiment, the speaker housing 2 includes a first case 21 and a second case 22, the first case 21 and the second case 22 enclose a first cavity, and the first case 21 is provided with an opening 211.
