With the advancement of science and technology, due to the needs of modern people for control comfort, general computer peripherals have been designed towards wireless design, such as: wireless computer peripheral devices such as wireless mouse, wireless keyboard, wireless remote control or wireless game joystick. , and the wireless transmission method is mainly radio frequency (RF) or bluetooth (Bluetooth) and other transmission methods, as long as a wireless receiver is plugged into the universal serial bus (Universal Serial Bus; USB) port on the computer device, it can be transmitted by The wireless receiver receives the signal transmitted by the wireless computer peripheral device, so that the computer device can achieve the function of wireless transmission and control with the wireless computer peripheral device, so that it can meet the needs of many computer families that are not limited to the wired transmission mode. Restrictions, but more ideal for freely controlling wireless computer peripheral devices.

The structure of the wireless receiver used in general computer peripherals currently on the market is roughly composed of a USB head with a USB interface, a signal receiving module combined behind the USB head and electrically connected to it, and a cover behind the USB head. It is composed of the housing of the signal receiving module, so that the USB head of the wireless receiver can be directly plugged into the USB port on the computer device to achieve the purpose of receiving signals.

However, in terms of actual design, the length of the USB head is roughly a standardized size. When adding the length of the signal receiving module and the housing, the overall length of the wireless receiver is generally already the same. It is more than 1 to 2 times the standard size of the USB head, and the overall length is at least about 4 cm or more. In this way, for some wireless computer peripheral devices with storage space inside to accommodate the wireless receiver, the longer the wireless The receiver tends to take up internal space, especially for wireless mice. If a wireless receiver with a long length is used, it will make the design of the mouse manufacturer difficult, making it difficult to arrange other internal components, increasing the design cost, and making the volume difficult.
