3, take some time is necessary to share with you! If solved don't forget to click the thumbs up for encouragement.
4, the ready-made machine generally will not have too much noise, you can try to unplug all the signal lines from the machine, and then start, turn on the volume to listen to whether there is noise. Good amplifiers only have ears close to themYou can hear the squeak, the general machine will have some noise. After the empty test, plug in the signal line, and listen again, it is normal for the noise to increase. Connected to the audio source, the noise should be low.
The circuit is designed with a switching power supply car wireless charging squeak , in which the switching transformer of car wireless charging squeak will make a squeak noise car wireless charging noiseTacks , which is a sound with a higher oscillation frequency when the magnetic core is not tight. It's a transformer. They all make sounds just big and small. The squeak emitted by the high-frequency transformer is not loud and has no effect on the circuit and can be ignored.
The lithium battery of the charging treasure is the same as that of the mobile phone, most of them are 7V, such a voltage is not able to charge the mobile phone, so the charging treasure will boost to about 5V, this process needs to boost the coil, Car wireless charging squeak You hear the sizing sound is it issued, betterThe power bank may be quieter. The inductance on the mainboard of the charging bank occurs in the high-frequency electromagnetic resonance, which has nothing to do with it.
Mi charger. If it is wireless charging, sometimes car wireless charging squeak He has some sound is very normal, so do not worry about this is also a normal phenomenon when he charges, if the sound is larger, you can go to the millet after-sales consultation to check.
