There are many reasons for the failure of the speaker unit. The following is a detailed analysis of the causes of the failure in general. When you encounter the failure of the speaker unit in the future, you can eliminate them one by one and deal with them;
Elastic wave: The main failure problem is that the elastic wave is prone to elastic fatigue due to the different stability of the material under the long-term mechanical movement, which will cause the following points:
The elastic wave is deformed, which causes the displacement of the voice coil, and the deviation of the voice coil from the center causes the rubbing of the coil.
If the bounce wave passes through the soft voice coil and collides with the bottom of the T iron, it will really cause the sound of hitting the steel.
The elastic wave and the voice coil sticking center glue are deteriorated (the voice coil is overheated, or the glue is not strong enough and the hardness is insufficient), resulting in the separation of the center part.
Diaphragm: The horn diaphragm is made of various materials such as paper, metal, PP, etc. Under the change of cold and hot temperature under long-term use, the paper cone is affected by moisture and moisture and other factors, which will cause the weight of the paper cone to change and deteriorate. , it will change the original sound quality and timbre, but no abnormal sound will appear. The fault may be caused by the following reasons:
The center part of the voice coil is degummed. Under long-term overuse, the overloaded power output will make the voice coil overheat, causing the center glue to deform, which will cause the degumming to produce noise.
When the power output is too large and the diaphragm vibrates violently for a long time, the heat resistance of the glue is sufficient at this time, and the rigidity of the paper cone is not enough, which will cause the paper cone to deform and rupture, even if abnormal sound occurs. .
Human damage and insect bites can also cause damage and abnormal sounds.
Suspension: The suspension of the speaker is mainly composed of sponge, rubber, cloth and other materials. The reasons for the failure are as follows:
Sponge foam edge or rubber or cloth edge, etc., after long-term vibration and the influence of climate, the sponge will deteriorate and corrode.
Bug bites, vandalism, etc.
Dust cover: The reasons for the failure are as follows:
The dust cover is degummed and loose, which will cause noise and so on when it collides with the paper cone.
The concave dust cover will also cause abnormal sound, which can be improved by replacing it.
