1. Poor performance of the broadcasting system, resulting in a decrease in the magnetic properties of the magnetic steel. The sensitivity of the speaker mainly depends on the magnetism of the permanent magnet, the quality of the paper basin, and the quality of the assembly process. The ferromagnetic object can be used to touch the magnetic steel, and the strength of the magnetic steel's magnetism can be roughly estimated based on the size of the attraction. If the magnetism is too weak, the speaker can only be replaced.
2. The magnetic core column is loose. When the magnetic core of the speaker is loose, it will be sucked aside by the magnetic plate, causing the voice coil to be squeezed and hindering normal sound production. During maintenance, the paper basin can be gently pressed by hand. If it cannot be pressed, it may be due to the voice coil being pressed by the core column, and it needs to be disassembled and re glued before resuming use.
3. The frequency divider is abnormal. When there is a faulty component in the frequency divider, the signal in the corresponding frequency band is blocked, and the speaker in that frequency band has a low volume fault. Emphasis should be placed on checking for short circuits in the crossover capacitor connected in parallel with the bass speaker, and for inter layer short circuits in the crossover inductance coil connected in parallel with the tweeter speaker.
