When some users use audio, they may encounter certain failures, which requires careful checking the problem.So what are the common faults of audio?What are the audio maintenance methods?Lets take a look at it together.
Sound repair: The sound of the speaker is abnormal
1. If the audio sounds good after opening a speaker, but at the same time, after opening two speakers, the sound becomes dry, the bass volume can not double, but the amount can be smaller or not significantly enhanced.Essence
2. Check whether the speaker cable connection at the outlet end is correct (the positive pole should be connected to the positive pole, and the negative electrode is connected to the negative electrode, which is generally red.), And then check whether the port connecting the port to the speaker is connected correctly.
3. If the mistake of the system connection causes reverse phase, it is enough to restore the correct connection.If the speaker unit is installed in reverse, the speaker is opened to check whether the connection line of the bass unit is connected.
4. If you are wrong, connect the two lines correctly.In addition, a battery can be used for polar test, and the tone line can be used lightly battery to see the movement direction of the speaker unit.The positive and negative pole of the speaker line and the positive pole of the battery are moved out of the bass speaker outward, the phase is normal.
5. If the horn shrinks, it is the case.In addition, if the speaker is installed in reverse, the easiest solution is to put the speaker line positive and negative rejuvenation on the output of the amplifier. When you encounter such problemsDont be irritable.
Audio maintenance: Play music silent
1. Speaks are generally impossible to burn all units high, medium, and bass, so if the sound is silent, please check whether VOD, front, and power amplifier first, and then check the speaker before checking.
2. If the speaker emits an abnormal sound of Bufu, remove the box network to check whether the box is leaked, and whether the unit is installed firmly on the box (sometimes the unit is not installed firmly.
3. During the use of high -power and large dynamics, the collision of the unit and the box of the unit and the box of the unit will also make a strange sound of air leakage. If each unit is installed firmly, listening carefully to which unit that determines the abnormal sound from.
4. Remove the units with abnormal sounds, level the unit on the ground, check whether the bubble is broken and dehydrated, and the dust cap is removed.The voice of Bufu is usually related to the above reasons.
5. If there is no dehydration and leakage, use the right finger as a triangular balance to naturally down the paper plate of the unit.When the normal unit is pressed downwards, there should be no noise, and the units that rubbing edges and sound rings will have noise.
6. If the unit is not installed, it does not emit a noise, and the installation is firm. If the unit is soaked or the dust cap is removed from glue, the agricultural machine glue (glue for the glue for leather shoes on the side of the road) can be sealed with natural air drying.
7. Check whether the contact point of the sound box iron mesh and the box has no foam tissue bars.If the speaker unit is burned, it should be repaid for manufacturers, because the sound coil and paper basin will affect the sound.
