When the wireless microphone set is used, the user can first press the setting button 323 to start the first micro processing unit 322. At this time, the first micro processing unit 322 drives the identification unit 325 to send an identification via the first communication unit 321 . The code 'receives a command mom via the first-communication list & 321. The identity identifying unit 45 first identifies whether the identification code received by the second communication unit 41 matches the built-in identification code. If the identifier matches, the command code received by the second communication unit 41 is transmitted to the second micro processing unit. 42. If the identification code is incorrect, the command code will not be sent back, and the wireless receiving host 4 has no action. After receiving the command code, the second micro processing unit 42 drives the frequency setting unit 43 to search for the unpaired pairing frequency of the group, and sends a pairing frequency information via the second communication unit 41. The pairing code is sent to the first communication unit 321, and the frequency setting unit also drives the wireless receiving unit 44 to search for the signal sent by the line transmitting unit 324 by the pairing frequency. After receiving the pairing code, the first micro processing unit 322 drives the wireless transmitting unit 324 to change the frequency of the transmitting signal, that is, adjusts the transmission frequency to the pairing frequency. At this time, the wireless transmitting unit 324 The frequency matching is completed with the wireless receiving unit 44. The wireless transmitting unit 324 can transmit the audio signal output by the microphone body 31 to the wireless receiving unit through the pairing frequency, and output through the amplifier 100. In addition, the user may first force the frequency setting unit 43 to modulate and lock a set of pairing frequencies 'by pressing the forced frequency shift button 46 of the wireless receiving host 4 and receive the command at the second micro processing unit 42. After the code, the pre-adjusted pairing frequency data is sent to the wireless microphone 3 via the second communication unit 41. However, the forced frequency shift button 46 is not necessary. In this embodiment, the identification code identification design of the identification unit 325 and the identity identification unit is private, so that the frequency between the wireless microphone 3 and the wireless receiving host 4 having the corresponding identification code data can be matched without any other defects. ',,, the sound of the line microphone device' does not affect the frequency of other wireless microphone devices. However, in the implementation, the identification unit 325 and the identity identification early element 44 are not necessarily in the wireless communication between the first communication unit of the above-mentioned if-wireless microphone 3 and the second communication unit 41 of the line receiving host 4. The communication mode △ transmission can drive the wireless receiving host 4 to search for lock--the frequency of the life and the transmission can drive the wireless microphone 3 to automatically change the matching frequency of the match. The communication frequency between the wireless microphone 3 and the wireless receiving host 4 is more matched. Simple, just press the setting button 323 to complete 10 200935958 - the frequency matching between the wireless microphone 3 and the wireless receiving host 4. In addition, the identification unit 325 and the identity recognition unit 45 have a design for identity recognition, which ensures the frequency matching between the wireless microphone 3 and the wireless receiving host 4, and is not affected by other wireless microphone devices, and is quite convenient and practical. . Therefore, the object of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change of the application scope and the description of the invention according to the present invention. And modifications, all of which are still within the scope of the present invention.
