Small volume

1. Poor speaker performance, magnetic steel's magnetic decrease. The sensitivity of the speaker mainly depends on the magnetic nature of the permanent magnet, the quality of the paper tray, and the advantages and disadvantages of the assembly process. You can use iron magnetic objects to touch magnetic steel. According to the attractive size, the magnetic steel magnetism is roughly estimated. If the magneticity is too weak, you can only replace the speaker.

2. Magnetic core column loose. When the magnetic core column of the speaker is loosened, the magnetic board will be inhaled to the side, causing the sound coil to be squeezed and hindered the normal sound. You can lightly press the paper plate during maintenance. If you do not move, it may be that the sound coil is pressed by the core column. It needs to be disassembled and reinstalized before it can be recovered.

3. Differential abnormality. When the component is poor in the frequency division, the signal of the corresponding frequency band is blocked, and the volume of the speaker in the frequency band has a small volume failure. Check whether the frequency division capacitance with the subwoofer speakers should be short -circuited, and whether the frequency frequency inductors coil with the high sound speaker is short -circuit.

Sound

1. There are debris in the magnetic gap. If there is a debris entering the magnetic gap, the sound coil will rub with the debris when vibrating, causing the sound to be hoarse.

2. The sound coil core. The sound coil position is incorrect, and the magnetic core is touched, causing the sound distortion. The sound of the sound should be corrected or replaced during maintenance.

3. Crimination of paper basins. If the damaged area is large, the paper plate should be replaced. If the damaged area is small, it can be repaired with a slightly thin paper plate or other tough toughness.

4, the box is poor. Box sealing is poorly sealed or the decorative mesh cover is not installed. In addition, if the box is too thin, the resonance will also cause sound abnormalities.
