[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present disclosure.It should be understood that the specific embodiments described in this specification are merely used to describe and explain the embodiments of the present disclosure, and are not intended to limit the embodiments of the present disclosure.All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0034] 1 is a schematic flowchart of a pairing method based on two-way communication according to an embodiment of the present disclosure. As shown in FIG. 1, the embodiment of the present disclosure provides a pairing method based on two-way communication, which is applied to a receiver. The pairing method includes the following steps:

[0035] Step S11: A target frequency point is determined, which is a frequency point with the least interference within a preset range of the receiver, or a preset frequency point stored in the receiver.

[0036] Step S12: The frequency point information of the target frequency point is transmitted to the microphone.

[0037] Step S13: Pairing information is received, which includes the identification information of the microphone.

[0038] Step S14: According to the pairing information, it is determined whether the identification information matches the preset identification information stored in the receiver.

[0039] Step S15: In response to the identification information matching the preset identification information, the operating frequency point of the receiver is switched to the target frequency point, and a pairing connection with the microphone is performed.

[0040] It should be understood that the method in this embodiment is performed by a receiver. Specifically, in step S11, the receiver may poll the operating frequency band and find a frequency point with the least interference within a preset range as the target frequency point. If the target frequency point is not found, the receiver may perform continuous searches until the target frequency point is found. The receiver may further determine a stored preset frequency number point as the target frequency number point. The preset frequency point may be a frequency point previously written into the receiver by a user according to actual conditions.

[0041] In step S12, after determining the target frequency point, the receiver may broadcast frequency point information of the target frequency point to the microphone. The frequency point information is used to represent the frequency value of the target frequency point. In step S13, after the receiver broadcasts the frequency point information of the target frequency point, microphones within the communication range may receive the frequency point information of the target frequency point. A microphone that needs to be paired may switch its operating frequency point to the target frequency point and initiate a pairing request, and the receiver may receive the pairing information transmitted from the microphone based on the target frequency point. The microphone identification information may be the microphone's chip_ID.

[0042] In step S14, the receiver pre-stores the identification information of the microphone that needs to be paired, i.e., the preset identification information. After receiving the pairing information transmitted from the microphone using the target frequency point, the receiver analyzes the pairing information to obtain the microphone identification information, and compares the analyzed microphone identification information with the stored preset identification information. In step S15, if the microphone identification information matches the stored preset identification information, the receiver switches the operating frequency point to the target frequency point and completes the pairing connection with the microphone.

[0043] In the above embodiment, the user only needs to turn on the power buttons of the microphone and receiver to complete the initial pairing of the microphone and receiver. The pairing process is automatically completed by the microphone and receiver, realizing non-inductive pairing between the microphone and receiver. The simple and reliable operation improves the user experience.

[0044] In one embodiment, before the target frequency point is determined in step S11, the pairing method may further include the following steps: The operating frequency point of the receiver is switched to the common frequency point.

[0045] Specifically, the receiver generally communicates wirelessly with the microphone via ultra-high frequency (UHF). The common frequency point is, for example, in the range of 650 MHz to 698 MHz. When a user turns on the power button of the receiver, the receiver first switches the operating frequency point to the common frequency point after powering on. After the target frequency point is determined, the receiver broadcasts the frequency point information of the target frequency point to the outside using the common frequency point, and it can be understood that the microphones within the communication range can receive the frequency point information of the target frequency point using the same common frequency point.

[0046] In one embodiment, determining the target frequency point in step S11 may include the following steps: The receiver is controlled to be in pairing mode The target frequency point is determined in a polling manner.

[0047] It should be understood that the receiver and microphone only need to be paired during the first connection for use. In other words, the steps of determining a target frequency point and performing a pairing connection need to be performed when the receiver is in pairing mode. Specifically, when connecting and using the receiver and microphone for the first time, the user turns on the power button of the receiver to control the receiver to enter pairing mode. The receiver polls the operating band to find a frequency point with the least interference within a preset range as the target frequency point, or determines a stored preset frequency point as the target frequency point.

[0048] In one embodiment, the pairing method may further include the following steps: Communication with the microphone is performed according to the target frequency point when the receiver is in an operational mode.

[0049] Specifically, after the receiver and the microphone are successfully paired for the first time, during subsequent use connections, i.e., when the receiver is in operation mode, the receiver can directly communicate with the microphone using the target frequency points, and there is no need to repeatedly perform the steps of determining the target frequency points and performing the pairing connection. For example, during subsequent use connections, the microphone collects the user's voice to obtain an audio signal, processes the audio signal, and then transmits the processed data using the target frequency points to the receiver. The receiver may receive data using the target frequency points, extract an audio signal from the received data, and play the audio signal from a speaker.

[0050] In an embodiment, the pairing method may further include the following steps: After successful pairing with the microphone, pairing success information is sent to the microphone.

[0051] Specifically, if it is determined that the identification information matches the preset identification information, the receiver switches its operating frequency point to the target frequency point, i.e., the receiver and the microphone are successfully paired. The receiver may use the target frequency point to send pairing success information to the microphone. After the microphone receives the pairing success information, the microphone determines that non-inductive pairing between the microphone and the receiver is completed.

[0052] According to the above technical solution, when the target frequency point is determined through the receiver, the target frequency point is the frequency point with the least interference within the preset range of the receiver or a preset frequency point stored in the receiver. The receiver transmits target frequency point information to the microphone. When the microphone receives the target frequency point, the microphone's operating frequency point is switched to the target frequency point. The microphone transmits pairing information based on the target frequency point. The pairing information includes the microphone's identification information. After the receiver receives the pairing information, it determines whether the identification information matches the preset identification information stored in the receiver according to the pairing information. If the identification information matches the preset identification information, the receiver's operating frequency point is switched to the target frequency point, and a pairing connection with the microphone is established. In this way, the pairing process between the microphone and the receiver is automatically completed, realizing non-inductive pairing between the microphone and the receiver. The simple and reliable operation improves the user experience.

[0053]

[0033] Referring to Fig. 2, Fig. 2 is another schematic flowchart of a pairing method based on two-way communication according to an embodiment of the present disclosure. As shown in Fig. 2, an embodiment of the present disclosure provides a pairing method based on two-way communication applied to a microphone. The method includes the following steps:

[0054] Step S21: Receive frequency point information of a target frequency point. The frequency point information of the target frequency point is transmitted by the receiver. The target frequency point is a frequency point with the least interference within a preset range of the receiver, or a preset frequency point stored in the receiver.

[0055] Step S22: Switch the operating frequency point of the microphone to the target frequency point.

[0056] Step S23: Pairing information is sent based on the target frequency point, and the receiver determines whether to perform pairing connection with the microphone according to the pairing information, where the pairing information includes the identification information of the microphone.

[0057] It should be understood that the method in this embodiment is performed by a microphone. Specifically, a microphone that needs to be paired may attempt to receive frequency point information of a target frequency point transmitted from a receiver within its communication range. If the microphone fails to receive the frequency point information of the target frequency point, it continues to attempt reception until it receives the frequency point information of the target frequency point. The microphone then switches its operating frequency point to the target frequency point and transmits pairing information to the receiver using the target frequency point. The pairing information includes microphone identification information, which may be, for example, the microphone's chip_ID. After receiving the pairing information, the receiver may analyze the pairing information to obtain the microphone identification information and compare the analyzed microphone identification information with preset identification information stored in the receiver. If the microphone identification information matches the stored preset identification information, the receiver may switch its operating frequency point to the target frequency point. That is, the microphone and the receiver use the same operating frequency point, and the microphone and the receiver are successfully paired.

[0058] In one embodiment, before the frequency point information of the target frequency point transmitted from the receiver is received in step S21, the pairing method may further include the following steps: Switch the working frequency point of the microphone to the common frequency point.

[0059] Specifically, a user turns on the power button of the microphone, and after the microphone is powered on, it first switches the operating frequency point to the common frequency point. It is understood that the microphone and receiver that need to be paired have the same frequency point. After the receiver uses the common frequency point to broadcast frequency point information of the target frequency point, microphones within communication range may receive the frequency point information of the target frequency point using the same common frequency point.

[0060] In one embodiment, the pairing method may further include the following steps: After successfully pairing with the receiver, receive pairing success information sent from the receiver.

[0061] Specifically, after the microphone has successfully paired with the receiver, the receiver may use the target frequency point to send pairing success information to the microphone, and after the microphone receives the pairing success information, the microphone determines that non-inductive pairing between the microphone and the receiver has been completed.

[0062] According to the above technical solution, the target frequency point is determined through the receiver, and the target frequency point is the frequency point with the least interference within the receiver's preset range or a preset frequency point stored in the receiver. The receiver transmits target frequency point information to the microphone. When the microphone receives the target frequency point, the microphone's operating frequency point is switched to the target frequency point. The microphone transmits pairing information based on the target frequency point. The pairing information includes the microphone's identification information. After the receiver receives the pairing information, it determines whether the identification information matches the preset identification information stored in the receiver according to the pairing information. If the identification information matches the preset identification information, the receiver's operating frequency point is switched to the target frequency point, and a pairing connection with the microphone is established. In this way, the pairing process between the microphone and the receiver is automatically completed, realizing non-inductive pairing between the microphone and the receiver. The simple and reliable operation improves the user experience.
