The wholesale TG149 bluetooth speakers will also encounter some faults during use, such as suddenly no sound, sometimes no sound, abnormal sound and so on. Today, let's take a look at the reasons for the abnormal sound of bluetooth speakers.
The first is that there are debris in the magnetic gap of the TG149 bluetooth speaker. If debris enters the magnetic gap, the voice coil will rub against the debris when it vibrates, which will cause the sound of the Bluetooth speaker to be hoarse.

In addition, the rubbing of the voice coil of the wholesale TG149 bluetooth speaker will also cause abnormal sound. If the voice coil is not positioned correctly, it will rub against the magnetic core, which will cause sound distortion. The position of the TG149 voice coil should be corrected or the voice coil should be replaced during maintenance.
In addition to the above, the rupture of the paper cone of the speaker and the poor box body of the wholesale TG149 bluetooth speaker are also the reasons for the abnormal sound. If the damaged area of the paper cone of the Bluetooth speaker is large, it should be replaced in time. If the damaged area is small, a slightly thinner paper cone or other paper with better toughness can be repaired. When the box of the wholesale TG149 bluetooth speaker is poorly sealed or the decorative grille is not installed firmly, it will cause a cracking sound during playback. In addition, the box plate of the wholesale TG149 bluetooth speaker is too thin to cause resonance and abnormal sound.
