1. The speaker performance is not good, and the magnetism of the magnetic steel is reduced
The sensitivity of SIP voip speaker for house mainly depends on the magnetism of the magnet, the quality of the paper cone and the quality of the assembly process. At this time, you can use a ferromagnetic object to touch the magnetic steel, and estimate the magnetic strength of the magnetic steel according to the magnitude of the suction force. If the magnetic force is too weak, you can only replace the speaker.
2. The magnetic core column is loose
When the magnetic core column of SIP voip speaker for house is loose, it will be attracted to the other side by the magnetic conductive plate, so that the voice coil will be squeezed and will not be able to sound normally. If you don't press it, it is possible that the voice coil is pressed by the stem, which needs to be disassembled and re-bonded before it can be used again.

3. The frequency divider is abnormal
When there are defective components in the frequency divider, the corresponding frequency band signal will be hindered, and SIP voip speaker for house in this frequency band will have a small volume failure. At this time, you should focus on checking whether the crossover capacitor connected in parallel with the woofer is in a short-circuit state, and whether the crossover inductor in parallel with the tweeter is short-circuited between layers.
