Why does the Bluetooth speaker have abnormal sound?
Abnormal sound
1. There is debris in the magnetic gap. If debris enters the magnetic gap, the voice coil will rub against the debris when vibrating, resulting in a hoarse voice.
2. Voice coil wipe core. The position of the voice coil is not correct, and it rubs against the magnetic core, causing sound distortion. Correct the position of the voice coil or replace the voice coil during maintenance.
3. The paper cone is broken. The paper cone should be replaced if the damaged area is large, and the smaller damaged area can be repaired with a thinner paper cone or other tougher paper.
4. The cabinet is bad. Poor sealing of the cabinet or improper installation of the decorative net cover, etc., will cause cracking sound during playback. In addition, if the cabinet plate is too thin, it will cause resonance and abnormal sound.

How about the battery of the Bluetooth speaker?
First of all, we must first introduce the type and quality of the built-in battery of the Bluetooth speaker.
1) Polymer battery
Advantages: safe and efficient, the soft package has no potential explosion hazard.
Disadvantages: There are many types, and the price difference between pure cobalt (good) and pure manganese (poor) polymer batteries is several times.
2) 18650 battery
Advantages: excellent performance, can reach the top level in charge and discharge (mostly used for laptop batteries), explosion-proof protection
Disadvantages: There are more disassembled batteries and old batteries. The same 18650 battery is 5-10 times the difference between good and bad
3) Aluminum shell battery
Advantages: the price is very cheap
Disadvantages: poor performance. Without any explosion-proof measures, the consequences of an explosion would be disastrous.
Polymer batteries are safer than other batteries and can be thinner. Among the built-in batteries of Bluetooth speakers, they are high-end and common batteries. Of course, 18650 batteries are also used more, and their capacity will be slightly larger, which is safer. The performance is still inferior to the polymer battery, the worst is the aluminum shell battery. But no matter what kind of battery is used, it must be equipped with a battery protection board. If there is no battery protection board, it must not be used, because without the protection board, the battery charging and discharging cannot be guaranteed, and the service life cannot be obtained. protect.
