1, the lithium battery of the charging treasure is the same as the mobile phone, most of them are 7V, such a voltage is unable to charge the mobile phone, so the charging treasure will boost to about 5V, this process needs to boost the voltage coil, you hear the sizzling sound is issued by it, the better charging treasure may sound relatively small. The inductance on the mainboard of the charging bank occurs in the high-frequency electromagnetic resonance, which has nothing to do with it.
2, millet charger.If it is wireless charging, sometimes 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.
3, if the noise is large, it may be the charger problem, you can change the charger to try charging. If the noise comes from the mobile phone, it may be a short circuit or leakage of the internal circuit of the mobile phone, or it may be a fault of the tail plug, and it needs to contact Xiaomi's after-sales service to repair the mobile phone to solve it.
1, this should be a prompt sound out, and can not change the sound, so you can not change the sound.
2, plug contact is not good. The official website of the Apple mobile phone announcement information that when the Apple mobile phone connects to the wireless charger, the prompt sound is sometimes large and sometimes small. The iPhone is a smart phone series developed by Apple Inc., equipped with its iOS operating system developed by Apple.
3, the battery power supply circuit caused by the failure to bootIn most mobile phones, after the mobile phone with a battery or external power supply, the power supply voltage is directly added to the power supply C, if the power supply voltage is not added to the power IC, the mobile phone can not be turned on. In other words, the power supply of the phone has two paths, one is battery power; The other way is the external interface power supply (with the charging dock power supply). When two power supplies are supplied at the same time, the external power supply is preferred.
4, in the phone Settings menu, click [battery], click the option of [wireless charging Settings], turn on the switch on the right of [charging silent mode], the specific steps are as follows. Tool: iPhone1ios1 Local Settings Click the battery. Click [battery] in the phone Settings menu, as shown in the picture below. After clicking on wireless charging, click on the option of "wireless charging Settings", as shown in the picture below.
Personal think and charging equipment is related to wireless charging sound is where wireless charging sound is where 80W wireless charging seat built-in cooling fan Wireless charging sound is where , the default charging speed wireless charging mode is opened (feel the noise can be manually closed), we can hear the "buzz" sound of the fan in the process of charging, and when the hand is near the bottom of the wireless charging seat, we can also feel the cool wind blown by the fan. I hope I can help you.
is related to current and voltage. The constant sizzling sound comes from the inductor coil inside the mobile power supply. When the mobile power supply is external, it is necessary to start the inverter circuit, and the inverter circuit must produce a certain frequency of alternating current when working, which belongs to the audio rangeNeed to be converted through the inductor coil, under the action of a large current, the coil will vibrate, and the generated sound will be transmitted out, so there is wireless charging sound is a subtle squeak.
Click on the phone Settings page, select Sound and Vibration, then select Advanced Sound Settings, you will see the system Sound and vibration keys. After clicking, turn off the charging sound effect.
Like when the induction cooker is put on the pot, there is a feeling of vibration and buzzing. Low efficiency and high heat. Induction cooker plus cooling fan can be started. There is no
