The wireless microphone consists of a wireless microphone and a wireless receiver, and the wireless microphone and the wireless receiver work in the same frequency channel, so that audio transmission can be realized. In actual use, due to factors such as electromagnetic interference in the environment, the audio quality of each channel is not the same, and therefore, before the microphone is used, the frequency matching processing between the microphone and the receiver needs to be performed. In the existing frequency alignment method based on the microphone system, frequency alignment is usually performed through an infrared transmission technology, after a receiver searches a target channel, an infrared frequency alignment point of a wireless receiver is aligned with an infrared frequency alignment point of a microphone, and a frequency alignment key of the wireless receiver is pressed to complete frequency alignment.

Example 1
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a frequency matching method based on a microphone system according to an embodiment of the present disclosure. The method is applied to a receiver of a microphone system. The frequency alignment method based on the microphone system comprises the following steps:

In this embodiment of the present application, if no valid data packet (audio data or handshake data sent by a microphone) is resolved within a preset time period, the system enters an occasional state, and step S205 to step S208 are executed.
S205, judging whether the current frequency-frequency duration exceeds a preset time period, if so, executing a step S206; if not, executing step S204 to continuously determine whether handshake data sent by the microphone in the microphone system is received on the first preset public channel.

If the correct audio data packet is analyzed on a certain channel (i.e. the second audio data is received), the normal working state is jumped to. If the correct audio data packet is not resolved yet when the full-band traversal is completed, the working state of the receiver is switched from the accidental state to the handshake state, and step S205 is executed to determine whether handshake data sent by a microphone in the microphone system is received.
In the embodiment of the present application, the sporadic state is to handle the situation of unexpected power failure of the receiver.
After step S207, the following steps are also included:
and S208, determining second channel information for receiving second audio data.
And S209, controlling the receiver to enter a normal working state according to the second channel information, and ending the process.

In the embodiment of the application, the receiver is provided with a radio frequency receiving module and a radio frequency transmitting module, when the working state of the receiver is in a handshaking state, only the radio frequency receiving module of the receiver is turned on, channels are circularly switched on the first preset public channel, and the received data packet is analyzed. If the handshake information packet is analyzed on a certain public channel, the radio frequency receiving module is closed, the radio frequency transmitting module is opened, and the cleanest channel (target channel) and other state information are packaged into paired frequency information to be sent to the microphone.

and if not, searching the target channel in the preset channel.
In the above embodiment, as shown in fig. 8, when the receiver is in a normal operation state, the channel in operation is periodically saved, and the receiving condition of the audio data packet is monitored and recorded in real time. If the third audio data transmitted by the microphone cannot be received continuously for many times or for a long time (i.e. a preset time period) within a communicable distance, the method jumps to a channel searching state, and executes step S201 to switch the communication channel of the receiver to a first preset public channel, and search for a target channel in the preset channel, so as to handle the situation that the microphone is unexpectedly turned off or a strong interference signal occurs during the communication.
In the embodiment of the application, the receiver can quickly send the searched target channel to the microphone. And the whole frequency alignment process is transparent to the user, the user does not need to participate, and the user can obtain a high-quality communication link after the receiver and the microphone are started up no matter how the environment changes. Therefore, system faults caused by manual misoperation are reduced, and maintenance cost is reduced. Meanwhile, in the frequency alignment process, the receiver starts the transmitting module only when successfully receiving the handshake information, and the handshake information lasts for a short time, so that the interference to other receivers is small.
It can be seen that, by implementing the frequency alignment method based on the microphone system described in this embodiment, a communication channel can be quickly searched, frequency alignment between the microphone and the receiver can be automatically completed, manual operation is not required, and frequency alignment efficiency is improved.
