The wireless receiving device 1 shared by computer peripheral equipment of the present invention can be used to receive wireless signals transmitted by different types of computer peripheral equipment wireless transmitting devices, and has a learning function, including a wireless receiving circuit 11, a microprocessing circuit 13, an interface Circuit 15, a reset circuit 17 and an oscillation circuit 19, wherein:

The wireless receiving circuit 11 is used to receive the wireless signal transmitted by the wireless transmitting device, which adopts frequency shift keying modulation communication technology to increase the ability of anti-noise interference, wherein the wireless transmitting device can be respectively a wireless keyboard 2 and a wireless mouse 3 , wireless remote controller 4 (as shown in Figure 4) or other wireless transmitting devices.

The wireless keyboard 2, the wireless mouse 3, and the wireless remote controller 4 are listed below as wireless transmitting devices for illustration, wherein each wireless transmitting device is provided with an identification code representing its type, and the identification code is determined by the product code and the identity code. Composition, that is, different types of wireless transmitting devices use different product codes as a distinction, and even several wireless transmitting devices of the same type, although their product codes are the same, can also be distinguished by using different ID codes.

The micro-processing circuit 13 is used to identify and decode the received wireless signal transmitted by the wireless transmitting device, so as to distinguish the type of the wireless transmitting device and the transmitted information, and convert it into a control signal. The wireless signal is composed of an identification code and information, and the information is used to represent the action information sent by the wireless transmitting device.

The interface circuit 15 is connected between the output terminal of the micro-processing circuit 13 and the computer for receiving the control signal and outputting it to the computer. In addition, the interface circuit 15 conforms to the transmission port specification of the Universal Serial Bus.

The reset circuit 16 is composed of a resistor R1 and a capacitor C1 connected in series, and its node is connected to the reset input terminal RES of the microprocessing circuit 13 for initializing the microprocessing circuit 13 .

The oscillation circuit 19 is composed of capacitors C2, C3 and quartz crystal Y1. The capacitors C2 and C3 are connected in parallel with the quartz crystal Y1 after being connected in series. The nodes of the capacitors C1 and C2 are grounded. The two ends of the quartz crystal Y1 are respectively connected to the clock signal input of the microprocessing circuit 13.
