Today to share with you millet wireless car running bad road noise knowledge, which will also explain the millet wireless car abnormal sound, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>1, this situation is not normal, the general mobile power supply will not make a sound. The reasons for this situation may be: 1, there may be water vapor on the mobile power motherboard, resulting in a slight short-circuit sound on the motherboard. 2, mobile power motherboard in the boostThe sound made during the process, but this sound is usually so small that it is almost inaudible.
2, personal think and charging equipment, millet 80W wireless charging base built-in cooling fan, charging the default open speed wireless charging mode (feel the noise can be manually closed), we can hear the fan in the process of charging "buzz" sound, hand near the bottom of the wireless charging base, can also feel the cool wind blowing out of the fan. I hope I can help you.
3, this is often caused by poor data line contact, replacing a good data line can solve the problem, after replacementStill can't use is the phone problem, need to repair. When charging, ding-dong ding-dong is the phone switches between charging and disconnecting two states.
1, there are several situations when the electric car charger is charging: the battery charger has fan heat dissipation, for a long time, the fan has ash or the fan roller oil is less, there will be a big noise, that is, the noise is heard, in this case, the fan roller can be solved by adding lubricating oil. The high-frequency magnetic core inside the charger is loose. usableThe paper is tightened and then sealed with paraffin and hot melt adhesive.
2, the battery car charger when charging the buzz is due to the noise emitted by the rotating friction of the cooling fan, if the battery car is placed in a high temperature area environment charging, it will cause the charger cooling fan rotation speed acceleration, which will increase the noise.
3, generally just the sound of the fan running. During charging, the internal chip heats up. The internal fan must dissipate heat normally. During the operation of the charger, fans and temperature control are indispensable. Regular buzzing is normal. If there's a really loud noise, it could beAffected by damaged charger. It is recommended to repair or replace the charger. If the charger is used for a long time, dust may also appear inside the charger.
4, This is normal, you don't have to worry. Electric cars are a common means of transportation. The main components of an electric vehicle include the frame, the motor, the battery and the controller. The controller is used to control the entire vehicle circuit. Without a controller, an electric car would not be able to drive properly. The controller is usually secured under the rear seat. The motor is the source of electric vehicle power, and the motor can drive the electric vehicle forward.
5, the sound of the electric car charger may be due to the chargerThere is a relationship between current and voltage. The constant sizzling sound comes from the inductor coil inside the mobile power supply. The mobile power supply needs to start the inverter circuit when the inverter circuit works to produce a certain frequency of alternating current, which belongs to the audio range, and needs to be converted by the inductor coil, under the action of the larger current, the coil will vibrate, and the generated sound will be transmitted, so there is a small 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.
Mi 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.
A switching power supply is designed in the circuit, where the switching transformer will make a squeaking noise, which is a sound with a higher oscillation frequency because 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 sizzling sound of the charging treasure is the low-frequency clutter generated during the operation of the switching power supply, which is heard by the human ear through the magnetic core vibration of the inductor. Normal switching power supply design will try to avoid this situation, hear such a sound is a product defect, generally does not affect the use. As Xiaomi is a big brand, the chance of such a mistake is not high. There are many imitation products of Xiaomi charging treasure on the market, and the quality is naturally less than the original products.
