Amazon clock wireless audio how to adjust the time

First, long press Amazon Clock Wireless chargerPress the power button to start the machine and enter the startup state. In the startup state, press and hold the power button to enter the OFF standby state. Second, in the standby state, short press the power button. Finally, the clock will appear, and the hour hand part begins to blink, press the add or subtract key to adjust the hour hand, you can adjust the Amazon clock wireless audio charging time.

. The kindle can connect to a wireless network, so we can send e-books to email, or download them directly from Amazon. From the second version of the kindle, it has a light adjustment function, and you don't have to be afraid of hurting your eyes when reading at night.

Finally, the device will confirm and stop the alarm.

Does wireless charging technology have requirements for the number of layers of pcb

1, for example, for the 6-10 layer of memory module PCB design, the choice of 10/20mil (drill/pad) hole is better, for some high-density small size boards, you can also try to use 8/18Mil hole. Under the current technical conditions, it is difficult to use a smaller size of the hole (when the hole depth exceeds 6 times the diameter of the hole, it is impossible to ensure that the hole wall can be uniformly plated with copper); Through hole for power supply or ground wireA larger size can be considered to reduce the impedance.

2, in the range of ravg 0~ 0.08m, the output power increases first and then decreases with the increase of coil turns; In the range of ravg 0.08~ 0.4m, the output power decreases first and then increases and then decreases with the increase of coil turns. For a fixed operating frequency, the quality factor Q mainly depends on the shape and size of the coil and the material used. Standard coil technologies (such as wire winding coils and PCB coils) generally specify quality factor values.

3, but wireless charging is not yetIt can transmit as far as WiFi, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally a distance of about 3~5mm is better, this kind of wireless charging technology uses magnetic induction wireless charging technology. Wireless charging requires a transmitter and a receiver. The transmitter is the wireless charger, the receiver is the mobile phone and so on. There is a coil at the transmitting end and a coil at the receiving end.

4, wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS-tube, control chip, protocol chip.

5, specifically, Wanan technology shares in the United States wireless charging leading enterprise, Tesla wireless charging supplier Evatran company, to obtain wireless charging core technology; Shuobed magnetic resonance wireless charging technology is the focus of the company's research and development direction, has obtained magnetic resonance wireless charging system utility model patent.
