1, the charging circuit is broken Wireless audio can not charge what happened , if there are conditions to change a charging IC.
2, the PCD8072x baseband chip is the core of the Nexperia 820 cordless phone system solution, which can handle different transmission standards such as WiFi, Bluetooth, DECT (including US standard DECT), and WDCT. Customers currently using Philips Nexperia cordless phone system solutions will also be able to easily add VoIP capabilities to their existing products.
3, problem two: car blueHow to pair teeth and mobile phones first see whether the two devices have Bluetooth function (if it is a computer also need to correctly install Bluetooth driver) Wireless audio can not charge what happened ; Secondly, see whether the device opens the Bluetooth function (do not open the device can not be found) Wireless audio can not be charged what happened ; Again, connect the two devices successfully (typically using a PIN and pairing code).
4. First, go to Settings and click on Sound and Vibration. Second: Open the wireless sound transmission switch, and click the need to connectConnected speaker or Bluetooth headset device. Third, click OK Connection. Note that when using connected Bluetooth headphones, place the phone near the sound source. When connecting the Bluetooth speaker, hold the phone and speak to the microphone.
Huawei Bluetooth audio can not be charged Wireless audio can not be charged What is going on , common reasons and solutions are as follows Wireless audio can not be charged What is going on : The charger is broken, replace the charger. Charging data cable is bad, replace the data cable is good. The battery cannot be charged and needs to be replaced. Speaker motherboard power management line fault, need to repair audio motherboard.
Huawei Bluetooth speaker hw2020 charging is not bright for the following reasons. The speaker power switch is damaged. The AC fuse is destroyed. The power transformer is damaged. The rectifier circuit is damaged. The DC fuse is damaged. There is a component disconnect (breakdown) on the circuit board, resulting in damage to the power supply or fuse.
See what is broken and solve it according to the situation. If Huawei Cygnet Bluetooth speaker is chargedThe device is broken, replace the charger. If the data cable of Huawei Cygnet Bluetooth speaker charging is bad, replace the data cable. If the battery of the Huawei Cygnet Bluetooth speaker cannot be charged, replace the battery. If the power management cable of the speaker board of Huawei Cygnet Bluetooth speaker is faulty, repair the speaker board.
There may be the following reasons: The charger output voltage is too large or too small Wireless audio can not be charged What happened , the standard should be between 5-5 volts. Charging line transmission voltage is too large or too small Wireless audio can not be charged what is going on , the standard should be between 5-5 volts. Battery contact is poor, or the protection board is damaged, you can check it with a voltmeter, or hand it over to after-sales treatment. The battery's protection plate is protective, and when the voltage is lower than or higher than the required voltage, it will automatically protect.
Hello: -- ★ The failure of "charging does not enter the electricity" should be found from three aspects: ①, the battery itself; ②, charging cable; ③ Charger. ★ Rechargeable batteryAging, excessive discharge (overuse, resulting in too low voltage), and oxidation of the contact point of the rechargeable battery, poor contact, will make the battery can not be charged normally.
The audio may not be charged because: if the charging cable is plugged in, the charging light is on and the charge is not charged, there is a problem with the audio and it needs to be sent for maintenance inspection. If the light is not on, it is possible that the charger has a problem, you can replace a charger to try. If the charger is not original, it may be that the polarity of the charger is reversed (positive and negative electrodes are reversed).
No matter what equipment, as long as it is the battery charging power supply mode can not be charged: the external charging equipment problem and the charging line, the interface contact is poor, the internal battery to the interface line contact is poor, the internal charge control circuit, the circuit may fail, the battery itself is damaged.
The current situation can rule out the problem of the data cable, the audio seems to listen to your meaning can be plugged in, the audio is no problem, and the audio can not be used without the battery, so the audio and the battery connection is no problem, thatThe problem appears in the battery protection circuit, you can not repair it, remember the battery model, buy a piece online, or have an old Nokia mobile phone at home can remove the battery to try to install.
There are two possibilities, one is that the machine is faulty, the program or the part is damaged; The other case is that the battery needs to be charged, and it can be learned when it is charged for a period of time and then turned on. If the battery is exhausted, the voltage will be relatively low, the lower limit voltage of the general lithium-ion battery is slightly less than 3V, and the Bluetooth speaker needs more than 6V to work, because the boot needs to consume power, so the speaker will automatically shut down after opening due to low power.
bv200 Bluetooth speaker is not connected to the specific how to operate: the phone opens the Bluetooth search status, open (see any device). When the Bluetooth speaker is off, press and hold the switch key for about 7 seconds until the red light and blue light alternately flash. The phone displays Bluetooth audio information and confirms the connection, within 10 meters of use. The required pairing code is 0000.
The small hole on the Bluetooth speaker is a key to restore the factory key, the Bluetooth speaker through the Bluetooth signal and the mobile phone, Bluetooth device is connected well, you can accept the Bluetooth audio of the mobile phone for playback, if the speaker is down, poor transmission, and so on
