[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0044] SUMMARY

[0045] Wireless microphones are widely used in various occasions due to their convenience in carrying and using. Before use, the wireless microphone needs to be paired with a receiver so that the communication channels of the two are the same, thereby realizing wireless communication between the two.

[0046] However, the current pairing method of the wireless microphone and the receiver is relatively cumbersome, for example, by pressing the pairing button on the wireless microphone and aligning the infrared emitter on the wireless microphone side with the infrared receiver on the receiver side to pair. This method of pairing the wireless microphone and the receiver by means of additional equipment is prone to compatibility problems between the additional equipment and the wireless microphone or the receiver. Moreover, due to the wide use of wireless microphones, there may be multiple microphones working at the same time in the same place. Since manual selection of the communication channel is arbitrary, the utilization rate of the spectrum resource is low, and the same frequency interference problem is prone to occur between the wireless microphones.

[0047] In summary, the current pairing method has the defects of complicated pairing process, low spectrum resource utilization rate, weak compatibility between products, and easy occurrence of same frequency interference.

[0048] Exemplary System

[0049] Figure 1 The system architecture schematic diagram of a wireless microphone system 100 provided by an exemplary embodiment of the present application is shown. As shown in the figure, Figure 1 The wireless microphone system 100 includes a wireless microphone 110 and a receiver 120, that is, Figure 1 which shows an application scenario of pairing the wireless microphone 110 and the receiver 120.

[0050] In an embodiment, the receiver 120 can determine the pairing information, modulate the carrier according to the pairing information to obtain a modulated signal, and play the modulated signal by using the speaker, wherein the modulated signal is a sound signal. The wireless microphone 110 collects the modulated signal and demodulates the pairing information from the modulated signal, and then configures the wireless communication module of the wireless microphone 110 according to the pairing information. Here, after determining the pairing information, the receiver 120 can configure the wireless communication module of the receiver 120 according to the pairing information. In this way, the communication channels (such as the communication frequency) of the wireless communication modules of the receiver 120 and the wireless microphone 110 are the same, that is, the pairing process is completed. After the pairing is completed, the wireless communication between the wireless microphone 110 and the receiver 120 can be realized.

[0051] In the embodiment, the speaker can be a part of the receiver 120, or be connected with the receiver 120 so as to be driven by the receiver 120 to emit sound.

[0052] In the embodiment, the specific structure of the wireless microphone 110 can refer to the specific structure of the wireless microphone 700 provided below, and the specific structure of the receiver 120 can refer to the specific structure of the receiver 600 provided below.

[0053] In an embodiment, the wireless microphone system 100 can include a plurality of wireless microphones 110 and a plurality of receivers 120.

[0054] It should be noted that the above application scenarios are only shown for the purpose of facilitating the understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited thereto. On the contrary, the embodiments of the present application can be applied to any scenario that can be applicable.

[0055] Exemplary method

[0056] Figure 2 A flowchart of a pairing method provided by an exemplary embodiment of the present application is shown. Figure 2 The method is applied to a receiver. As shown in Figure 2 The pairing method includes the following contents.

[0057] 210: Determine the pairing information, the pairing information being used to indicate information required for the wireless microphone to communicate with the receiver.

[0058] Specifically, the information required for the wireless microphone to communicate with the receiver can be frequency information, and the frequency information can include a frequency point or a frequency band, etc., wherein the frequency point can be a communication frequency or a number corresponding to the communication frequency. The pairing information can include the frequency information itself, or include a string representing the frequency information.

[0059] The frequency point / frequency band corresponding to the pairing information determined by the receiver is an idle frequency point / idle frequency band, i.e., no other wireless microphone is currently using the frequency point / frequency band for wireless communication.

[0060] In this embodiment, after determining the pairing information, the receiver can configure the wireless communication module of the receiver according to the pairing information.

[0061] Of course, in other embodiments, the pairing information can also include other contents, i.e., the specific content of the pairing information can be set according to actual needs, as long as it can indicate the information required for the wireless microphone to communicate with the receiver.

[0062] 220: Modulate the carrier according to the pairing information to obtain a first modulated signal, wherein the first modulated signal carries the pairing information.

[0063] Specifically, the carrier can be amplitude modulated, phase modulated or frequency modulated according to the pairing information to obtain the first modulated signal. Different modulated signals can be obtained by modulating the carrier according to different pairing information.

[0064] 230: Play the first modulated signal by using a loudspeaker, wherein the first modulated signal is a sound signal.

[0065] The first modulated signal is played by using a loudspeaker, i.e., a sound signal (such as a sound wave) is played, so as to facilitate the wireless microphone to collect the sound signal. The wireless microphone can demodulate the first modulated signal to extract the pairing information from the first modulated signal, and configure the wireless communication module of the wireless microphone according to the pairing information.

[0066] Since the receiver and the wireless microphone use the same communication frequency, wireless communication can be achieved between the two. After the wireless microphone is paired with the receiver, the two can enter a working mode, i.e., the wireless microphone collects the user's voice to obtain a sound signal, processes the sound signal, and sends the processed data to the receiver through the wireless communication module. The receiver extracts the sound signal from the received data and plays the sound signal through a loudspeaker.

[0067] The pairing method provided in the embodiments of the present application can realize automatic pairing between the wireless microphone and the receiver, and simplify the pairing process, by determining pairing information, modulating a carrier according to the pairing information to obtain a modulated signal, and then playing the modulated signal by a loudspeaker so that the wireless microphone can collect the modulated information and demodulate the pairing information from the modulated signal. In addition, since the pairing method is to play the modulated signal carrying the pairing information by the loudspeaker, and receive the modulated signal by the wireless microphone, the functions of the loudspeaker and the wireless microphone can be fully and reasonably utilized, and the pairing process can be realized without additional equipment, so that the complexity of the wireless microphone system can be reduced.

[0068] According to an embodiment of the present application, the pairing information includes a pairing frequency point, and the carrier has a fixed carrier frequency, wherein the modulating the carrier according to the pairing information to obtain a first modulated signal includes amplitude modulating the carrier according to the pairing frequency point to obtain the first modulated signal.

[0069] Specifically, the pairing information includes a pairing frequency point, which can be a specific frequency or a number corresponding to the specific frequency. The correspondence between the specific frequency and the number can be set according to actual conditions. The pairing frequency point can be represented by a decimal number, a binary number or other ways.

[0070] In the embodiment, the carrier can have a fixed carrier frequency, and the frequencies of the modulated signals obtained by amplitude modulating the carrier according to different pairing frequency points are the same, but the amplitudes of the modulated signals corresponding to different pairing frequency points are different.

[0071] In an embodiment, the amplitude of the modulated signal after amplitude modulation is a fixed value, and the amplitudes of the modulated signals corresponding to different pairing frequency points are different, so that the different pairing frequency points can be distinguished by the amplitudes of the modulated signals. In the embodiment, the mapping relationship between the pairing frequency points and the amplitudes can be set in advance. For example, the amplitude of the modulated signal corresponding to the pairing frequency point 400MHz is 1, and the amplitude of the modulated signal corresponding to the pairing frequency point 450MHz is 2. Since the embodiment adjusts the amplitude of the carrier according to the mapping relationship between the pairing frequency points and the amplitudes, the amplitude of the modulated signal can be fixed, so that the modulated signal can be guaranteed to be simple enough, thereby improving the anti-interference ability of the modulated signal and ensuring the accuracy of the signal transmission process.

[0072] In another embodiment, the amplitude of the modulated signal after amplitude modulation is changed, and the amplitude change rule of the modulated signal corresponding to different pairing frequency points is different, so that different pairing frequency points can be distinguished by the amplitude change rule of the modulated signal. For example, the pairing frequency point is represented by binary digits, and 0 in the pairing frequency point corresponds to no carrier output (amplitude is 0), and 1 in the pairing frequency point corresponds to carrier output (amplitude is not 0). Since the amplitude of the carrier in different time periods is adjusted according to different digits in the pairing frequency point in this embodiment, the type of pairing information that can be carried by the modulated signal is significantly improved, and the efficiency of signal transmission is improved. For example, the pairing frequency point is represented by n-bit binary digits, and the carrier in a fixed time period can have 2 n variations, i.e. 2 n modulated signals can be obtained. 2 n modulated signals can correspond to 2 n pairing frequency points, so that the type of pairing information that can be carried by the modulated signal is significantly improved; and the time length of the 2 n modulated signals is the same (for example, n seconds), which is relatively short, so that the efficiency of signal transmission is improved. In addition, since the amplitude change of the carrier in different time periods is adjusted according to the change of the digit in the pairing frequency point in this embodiment, the mapping relationship between the pairing frequency point and the amplitude does not need to be set in advance, so that the pairing process can be simplified.

[0073] According to an embodiment of the present application, the pairing information includes a pairing frequency point, and the carrier includes a plurality of time periods corresponding to a plurality of carrier frequencies, wherein the carrier is modulated according to the pairing information to obtain a first modulated signal, including: determining a carrier frequency corresponding to the pairing frequency point from the plurality of carrier frequencies according to the pairing frequency point; and amplitude modulating a time period corresponding to the carrier frequency in the carrier according to the pairing frequency point to obtain first modulated information.

[0074] Specifically, the pairing frequency point can be one of a plurality of selectable frequency points (such as in a frequency point list), and the carrier can include a plurality of carrier frequencies, which can correspond to the plurality of selectable frequency points one by one. Each carrier frequency corresponds to a time period. When the pairing frequency point is determined, the time period in which the carrier frequency corresponding to the pairing frequency point is located in the carrier can be amplitude modulated, and the carrier in other time periods remains unchanged, so that a modulated signal can be obtained. Since the modulated signal includes a plurality of time periods corresponding to a plurality of selectable frequency points, and the carrier frequencies of the plurality of time periods are different, the amplitude of the corresponding time period in the carrier can be adjusted to a preset value for different pairing frequency points, without the need to set the mapping relationship between the pairing frequency point and the amplitude in advance, so that the modulation process can be simplified.

[0075] Optionally, when the pairing frequency point is determined, the time period in which the carrier frequency corresponding to the pairing frequency point is located in the carrier can be amplitude modulated, and only the modulated carrier corresponding to the time period is selected as the modulated signal, so that the efficiency of signal transmission can be improved.

[0076] According to an embodiment of the present application, the pairing information includes a pairing frequency point, and modulating the carrier according to the pairing information to obtain the first modulated signal includes: determining at least one carrier frequency according to the pairing frequency point; and modulating at least one time period in the carrier according to the at least one carrier frequency respectively to obtain the first modulated signal.

[0077] In an embodiment, one carrier frequency can be determined according to the pairing frequency point, and different pairing frequency points can correspond to different carrier frequencies. When the pairing frequency point is determined, the carrier is modulated so that the carrier frequency of the obtained modulated signal is the carrier frequency corresponding to the pairing frequency point, wherein the carrier frequency of the modulated signal is a fixed value. In this way, the different pairing frequency points can be distinguished by the carrier frequency of the modulated signal. In this embodiment, the mapping relationship between the pairing frequency point and the carrier frequency can be set in advance. For example, the carrier frequency of the modulated signal corresponding to the pairing frequency point 400 MHz is 20 kHz, and the carrier frequency of the modulated signal corresponding to the pairing frequency point 450 MHz is 21 kHz. Since the frequency of the carrier is adjusted according to the mapping relationship between the pairing frequency point and the carrier frequency in this embodiment, the carrier frequency of the modulated signal is fixed, so that the modulated signal can be guaranteed to be simple enough, thereby improving the anti-interference ability of the modulated signal and ensuring the accuracy of the signal transmission process.

[0078] In another embodiment, multiple carrier frequencies can be determined according to the pairing frequency point, that is, the carrier frequency of the modulated signal after modulation is variable, and the change rule of the carrier frequency of the modulated signal corresponding to different pairing frequency points is different. In this way, the different pairing frequency points can be distinguished by the change rule of the carrier frequency of the modulated signal. For example, the pairing frequency point is represented by a binary number, 1 in the binary number corresponds to a first carrier frequency, and 0 in the binary number corresponds to a second carrier frequency. Since the carrier frequency of the carrier in different time periods is adjusted according to different digits in the pairing frequency point in this embodiment, the type of pairing information that can be carried by the modulated signal can be significantly improved, and the efficiency of signal transmission can be improved. For example, the pairing frequency point is represented by an n-bit binary number, so that the carrier of a fixed time length can have 2 n different changes, that is, 2 n different modulated signals can be obtained. 2 n different modulated signals can correspond to 2 n different pairing frequency points, so that the type of pairing information that can be carried by the modulated signal is significantly improved; and 2 nThe time length of the modulated signal is the same (for example, n seconds), which is relatively short, and thus the efficiency of signal transmission can be improved. For example, n = 3, and the pairing frequency point is 101, wherein 1 corresponds to the first carrier frequency 21 kHz, and 0 corresponds to the second carrier frequency 20 kHz. Thus, the modulated signal corresponding to the pairing frequency point is composed of a 1-second 21-kHz waveband, a 1-second 20-kHz waveband, and a 1-second 21-kHz waveband.

[0079] In addition, since the embodiment adjusts the carrier frequency of the carrier in different time periods according to the change of the number in the pairing frequency point, the mapping relationship between the pairing frequency point and the carrier frequency can be set in advance, and thus the pairing process can be simplified.

[0080] According to an embodiment of the present application, the pairing method further comprises: if the data transmitted by the wireless microphone is not received within a preset time, the step of playing the first modulated signal by the loudspeaker is performed again.

[0081] Specifically, after the first modulated signal is played by the loudspeaker, if the wireless microphone collects the first modulated signal and adjusts the communication frequency of the wireless communication module thereof to the frequency corresponding to the pairing information carried by the first modulated signal, the wireless microphone can transmit data through the wireless communication module thereon, and if the receiver receives the data, the pairing is successful. Here, the data transmitted by the wireless microphone can be a feedback signal corresponding to the successful configuration of the wireless communication module on the wireless microphone according to the pairing information, or can be data obtained by collecting the voice of a user, because the user generally tests the sound effect by his own voice in advance when using the wireless microphone.

[0082] If the data transmitted by the wireless microphone is not received by the receiver within a preset time, it can be that the wireless microphone does not collect the first modulated signal. For example, the loudspeaker is interfered by other sounds (noise) in the surrounding environment when playing the first modulated signal, so that the wireless microphone does not successfully collect the first modulated signal.

[0083] Therefore, after the loudspeaker plays the first modulated signal for more than a preset time, the receiver can play the first modulated signal by the loudspeaker again to realize the pairing between the wireless microphone and the receiver. Of course, if the data transmitted by the wireless microphone is not received by the receiver, it can also be that the wireless microphone itself has a device problem. Therefore, for the determined pairing information, the number of times that the receiver plays the first modulated signal by the loudspeaker can be set in advance, so that the cause of the pairing failure can be found in time, and time is saved.

[0084] The pairing method provided by the embodiment is more suitable for a scenario in which noise lasts for a short time, for example, a classroom is the application scenario of the wireless microphone, and the noise is a class bell. At this time, if the receiver does not receive the data sent by the wireless microphone within the preset time, the receiver can play the first modulated signal again by using the loudspeaker.

[0085] According to an embodiment of the present application, the pairing method further includes: if the data sent by the wireless microphone is not received within the preset time, adjusting the frequency of the carrier to obtain an adjusted carrier; modulating the adjusted carrier according to the pairing information to obtain a second modulated signal; and playing the second modulated signal by using the loudspeaker.

[0086] Specifically, if the data sent by the wireless microphone is not received by the receiver within the preset time, the receiver can obtain a second modulated signal according to the pairing information. The carrier frequency of the second modulated signal can be different from the carrier frequency of the first modulated signal. In the embodiment, the modulation process of obtaining the modulated signal can be amplitude modulation of the carrier. For example, the carrier frequency of the first modulated signal obtained by amplitude modulating the carrier according to the pairing information is 20 kHz. Since the data sent by the wireless microphone is not received by the receiver within the preset time, the receiver is triggered to increase the frequency of the carrier to obtain an adjusted carrier, and the adjusted carrier is amplitude modulated according to the pairing information, so that a second modulated signal with a carrier frequency of 21 kHz can be obtained. Of course, the frequency of the carrier can also be reduced to obtain the second modulated signal. In the embodiment, the frequency of the modulated signal is changed, which can effectively prevent the interference of noise on the modulated signal, and especially in a scenario in which noise lasts for a long time, the pairing between the wireless microphone and the receiver can be quickly realized.

[0087] According to an embodiment of the present application, the pairing information is determined, including: determining the pairing information when the receiver is in a pairing mode. The pairing method further includes: when the receiver is in a working mode, communicating with the wireless microphone according to the pairing information.

[0088] Specifically, when the wireless microphone and the receiver are powered on, no wireless communication connection is established between the receiver and the wireless microphone, and both are in a pairing mode. In the pairing mode, the receiver determines the pairing information, and based on the pairing information, the pairing between the wireless microphone and the receiver can be realized. After the pairing is successful, the wireless microphone and the receiver both enter a working mode. In the working mode, the receiver can control the wireless communication module on the receiver to communicate with the wireless microphone according to the communication frequency corresponding to the pairing information.

[0089] For example, the wireless microphone collects the user's voice to obtain a sound signal, processes the sound signal, and sends the processed data to the receiver according to a communication frequency corresponding to the pairing information. The receiver receives the data according to the communication frequency corresponding to the pairing information, extracts the sound signal from the received data, and plays the sound signal through a loudspeaker.

[0090] The embodiment determines the pairing information in the pairing mode, so that the wireless communication between the wireless microphone and the receiver can be realized based on the pairing information in the working mode.

[0091] According to an embodiment of the present application, the pairing information is determined by: when the receiver is in the pairing mode, selecting a first frequency point from a frequency point list; sending an inquiry message on a frequency corresponding to the first frequency point, the inquiry message being used to determine whether the first frequency point is idle; and if no response message is received within a preset time, taking the first frequency point as the pairing information.

[0092] Specifically, the receiver can store a frequency point list. In the pairing mode, the receiver can select a first frequency point from the frequency point list in a certain order, configure a wireless communication module on the receiver according to the first frequency point, and then send an inquiry message on a frequency corresponding to the first frequency point through the wireless communication module. If no other wireless microphone communicates with a corresponding receiver based on the first frequency point at this time, it indicates that the first frequency point is an idle frequency point and is not occupied. For example, if no response message is received within a preset time, the first frequency point can be taken as the pairing information for the pairing between the current receiver and the wireless microphone.

[0093] Further, the pairing information is determined by: if a response message is received within a preset time, selecting a second frequency point from the frequency point list as the first frequency point, and executing again the step of sending an inquiry message on a frequency corresponding to the first frequency point.

[0094] Specifically, if other wireless microphones communicate with corresponding receivers based on the first frequency point, the receiver will receive a response message sent by other wireless microphones (and / or corresponding receivers), which indicates that the first frequency point has been occupied. The receiver can select a second frequency point from the frequency point list and take it as a new first frequency point, and then send an inquiry message on a frequency corresponding to the new first frequency point, until an idle frequency point is determined.

[0095] The embodiment can select a first frequency point from a frequency point list in a certain order, and determine whether the first frequency point is an idle frequency point through inquiry, so that the selection of the idle frequency point can be orderly, the utilization rate of frequency spectrum resources can be improved, and the problem of co-channel interference can be avoided.

[0096] According to an embodiment of the present application, the pairing information is determined by: when the receiver is in the pairing mode, selecting a plurality of first frequency points from the frequency point list; sending an inquiry message on a frequency corresponding to each of the plurality of first frequency points, the inquiry message being used to determine whether the first frequency point is idle; if no response message is received within a preset time for the inquiry message, regarding the first frequency point as an idle frequency point, thereby determining at least one idle frequency point; and selecting a pairing frequency point from the at least one idle frequency point as the pairing information.

[0097] Specifically, the receiver can simultaneously select a plurality of first frequency points from the frequency point list, and send an inquiry message on a frequency corresponding to each of the plurality of first frequency points. If no response message is received within a preset time for the inquiry message (sent on a certain first frequency point), the first frequency point (idle frequency point) can be used as the pairing information for pairing between the current receiver and the wireless microphone. This embodiment can quickly determine the idle frequency point by simultaneously sending inquiry messages on frequencies corresponding to a plurality of frequency points, thereby improving the efficiency of pairing.

[0098] When there are multiple idle frequency points in the plurality of first frequency points, any idle frequency point can be selected as the pairing frequency point, or the idle frequency point with the best communication quality can be selected as the pairing frequency point. For example, the receiver can select an idle frequency point with the smallest packet loss rate from the plurality of idle frequency points as the pairing frequency point, thereby improving the communication quality between the receiver and the wireless microphone.

[0099] According to an embodiment of the present application, the frequency of the first modulated signal is greater than or equal to a preset threshold.

[0100] Specifically, the preset threshold can be 20 kHz, i.e., the frequency of the modulated signal is greater than or equal to 20 kHz. In this way, when the loudspeaker plays the modulated signal, the user will not hear the sound, i.e., automatic pairing between the receiver and the wireless microphone can be achieved without the user's awareness, thereby improving the user experience.

[0101] Alternatively, the preset threshold can be other values, such as 18 kHz, 19 kHz, etc. In this way, the frequency of the first modulated signal can belong to the audible frequency range of the human ear.

[0102] Specifically, since the loudspeaker can support playing of sound within a certain frequency range, the frequency of the modulated signal can belong to the audible frequency range of the human ear, thereby facilitating playing through the loudspeaker and reducing the requirement on the loudspeaker.

[0103] Further, the frequency of the modulated signal can belong to a high frequency range (for example, 18 kHz, 19 kHz, etc.) in the audible frequency range of human ears, i.e., the frequency of the modulated signal is higher than or equal to a preset threshold, so that the user can hardly hear the sound or hear a slight sound when the loudspeaker plays the modulated signal, so that the user experience can be improved to some extent. In addition, the use of high-frequency modulated signals can improve signal transmission efficiency and thus improve pairing efficiency. For example, when searching for an idle frequency point through multiple inquiries, the use of high-frequency modulated signals can significantly shorten the pairing time.

[0104] According to an embodiment of the present application, when there are two receivers simultaneously selecting the same frequency point and sending inquiry messages on the frequency corresponding to the frequency point, the two receivers will respectively receive response messages for the inquiry messages. For example, one of the two receivers will receive the response message sent by the other receiver because the communication frequencies of the wireless communication modules of the two receivers are the same. After the two receivers respectively receive the response messages for the inquiry messages, the two receivers can respectively select new frequency points and send inquiry messages on the frequencies corresponding to the new frequency points. In this way, the two receivers can avoid using the same frequency point to pair with the corresponding wireless microphone, and thus the same frequency interference can be avoided. In the embodiment, the receiver can select a new frequency point by a certain random function to avoid selecting the same frequency point again.

[0105] Figure 3 Fig. 4 shows a flowchart of a pairing method according to another exemplary embodiment of the present application. Figure 3 The embodiments are Figure 2 Examples of the embodiments, to avoid repetition, the same will not be repeated. For example Figure 3 As shown in the figure, the pairing method includes the following contents.

[0106] 310: In the pairing mode, determine the pairing information, and configure the wireless communication module of the receiver according to the pairing information, the pairing information being used to indicate the frequency information required for the wireless microphone to communicate with the receiver.

[0107] Specifically, a first frequency point can be selected from the frequency list, and an inquiry message can be sent on the frequency corresponding to the first frequency point, the inquiry message being used to determine whether the first frequency point is idle. If no response message for the inquiry message is received within a preset time, the first frequency point (idle frequency point) is taken as the pairing information, otherwise a new first frequency point is selected from the frequency list, and the inquiry process is repeated until an idle frequency point is determined, and the idle frequency point is taken as the pairing information.

[0108] Optionally, multiple first frequency points can be selected from the frequency point list at the same time, and the inquiry message is sent at the frequency corresponding to each first frequency point. If no response message to the inquiry message of at least one first frequency point is received within a preset time, a frequency point is selected from the at least one first frequency point as the pairing information.

[0114] 350: In the working mode, communicate with the wireless microphone according to the pairing information.

[0115] If the data sent by the wireless microphone is received within the preset time, it indicates that the pairing is successful, and both the wireless microphone and the receiver enter the working mode.

Figure 4 The embodiment is Figure 2 Examples of the embodiment, to avoid repetition, the same will not be repeated. For example Figure 4 As shown, the pairing method includes the following contents.

[0120] 440: Determine whether data sent by the wireless microphone is received within a preset time.

[0126] 470: In the working mode, communicate with the wireless microphone according to the pairing information.

[0127] Steps 470 in this embodiment can refer to the description of steps 350 in the above-mentioned Figure 3 embodiment.

[0128] Figure 5 As shown in the flowchart of the pairing method provided by another exemplary embodiment of the present application. Figure 5 The method of the wireless microphone, Figure 5 The method of the present application corresponds to the method in the above-mentioned embodiments, and the same parts can refer to the description in the above-mentioned embodiments. For example, Figure 5 As shown, the pairing method includes the following contents.

[0129] 510: Collect a first modulated signal, wherein the first modulated signal is a sound signal and is obtained by modulating a carrier according to pairing information by a receiver, and the pairing information is used to indicate information required for the wireless microphone to communicate with the receiver.

[0130] Specifically, the information required for the wireless microphone to communicate with the receiver, the specific meaning of the pairing information, and the acquisition process of the modulated signal can refer to the description in the above-mentioned Figures 2 to 4 embodiment.

[0131] In an embodiment, the wireless microphone only collects the sound when the decibel of the sound exceeds a certain threshold. This can avoid the problem that the wireless microphone collects multiple sounds when multiple speakers in a certain range play the modulated signal at the same time, and cannot be paired with the corresponding receiver. For example, there is a set of wireless microphone and receiver in each of multiple adjacent classrooms to be paired, and the receivers in different classrooms can obtain different modulated signals according to different pairing information. When the speakers in different classrooms play the corresponding modulated signal at the same time, the wireless microphone in a certain classroom can only collect the sound in the classroom according to the decibel of the sound, and will not collect the sound emitted by the speakers in other classrooms, because the closer the speaker to the wireless microphone, the higher the decibel of the sound emitted by the speaker. The threshold of the sound decibel in the embodiment can be set according to actual needs.

[0132] 520: demodulate the first modulated signal to obtain the pairing information.

[0133] The demodulation process is the inverse process of the modulation process, and is used to extract the pairing information from the modulated signal.

[0134] 530: configure the wireless communication module of the wireless microphone according to the pairing information.

[0135] Specifically, after obtaining the pairing information, the wireless microphone can configure the wireless communication module of the wireless microphone according to the pairing information, so that the wireless microphone and the corresponding receiver communicate at the same communication frequency.

[0136] The embodiment of the present application provides a pairing method, which determines the pairing information, modulates the carrier according to the pairing information to obtain the modulated signal, and then plays the modulated signal by the speaker so that the wireless microphone collects the modulated information and demodulates the pairing information from the modulated signal, thereby realizing the automatic pairing between the wireless microphone and the receiver, and simplifying the pairing process. In addition, since the pairing method is realized by playing the modulated signal carrying the pairing information by the speaker, and receiving the modulated signal by the wireless microphone, the functions of the speaker and the wireless microphone themselves can be fully and reasonably utilized, and the pairing process does not need to be realized by additional equipment, so that the complexity of the wireless microphone system can be reduced.

[0137] According to an embodiment of the present application, the pairing information includes a pairing frequency point, and the carrier has a fixed carrier frequency, wherein the demodulating the first modulated signal to obtain the pairing information includes: amplitude demodulating the first modulated signal to obtain the pairing frequency point.

[0138] Specifically, the pairing frequency point can be a specific frequency or a number corresponding to the specific frequency. The correspondence between the specific frequency and the number can be set according to actual conditions. The pairing frequency point can be represented by a decimal number, a binary number, or other ways.

[0139] In this embodiment, the carrier can have a fixed carrier frequency, and the frequency of the modulated signal obtained by amplitude modulation of the carrier according to different pairing frequency points is the same, but the amplitudes of the modulated signals corresponding to different pairing frequency points are different.

[0140] In an embodiment, the amplitude of the modulated signal after amplitude modulation is a fixed value, and the amplitudes of the modulated signals corresponding to different pairing frequency points are different, so that different pairing frequency points can be distinguished by the amplitude of the modulated signal. In this embodiment, the mapping relationship between the pairing frequency point and the amplitude can be set in advance. For example, the amplitude of the modulated signal corresponding to the pairing frequency point 400MHz is 1, and the amplitude of the modulated signal corresponding to the pairing frequency point 450MHz is 2. When the wireless microphone demodulates the modulated signal and determines that the amplitude of the modulated signal is 1, it can be determined that the corresponding pairing frequency point is 400MHz.

[0141] Since the amplitude of the modulated signal is adjusted according to the mapping relationship between the pairing frequency point and the amplitude in this embodiment, the amplitude of the modulated signal can be fixed, so that the modulated signal can be guaranteed to be simple enough, thereby improving the anti-interference ability of the modulated signal and ensuring the accuracy of the signal transmission process.

[0142] In another embodiment, the amplitude of the modulated signal after amplitude modulation is variable, and the amplitude variation law of the modulated signals corresponding to different pairing frequency points is different, so that different pairing frequency points can be distinguished by the amplitude variation law of the modulated signal. For example, the pairing frequency point is represented by a binary number, 0 in the pairing frequency point corresponds to no carrier output (amplitude is 0), and 1 in the pairing frequency point corresponds to carrier output (amplitude is not 0). The wireless microphone demodulates the modulated signal to determine the amplitude variation law of the modulated signal, and then determines the corresponding pairing frequency point.

[0143] Since the amplitude of the carrier is adjusted according to different numbers in the pairing frequency point in this embodiment, the types of pairing information that can be carried by the modulated signal are significantly improved, and the efficiency of signal transmission is improved. For example, the pairing frequency point is represented by an n-bit binary number, so the carrier of a fixed time length can have 2 n variations, i.e. 2 n modulated signals. 2 n modulated signals can correspond to 2 n pairing frequency points, so the types of pairing information that can be carried by the modulated signal are significantly improved; and 2 nThe time length of the modulated signal is the same (for example, n seconds), which is relatively short, and thus the efficiency of signal transmission can be improved. In addition, since the embodiment adjusts the amplitude variation of the carrier in different time periods according to the digital variation in the pairing frequency point, the mapping relationship between the pairing frequency point and the amplitude does not need to be set in advance, and thus the pairing process can be simplified.

[0144] According to an embodiment of the present application, the pairing information includes a pairing frequency point, and the carrier includes a plurality of time periods corresponding to a plurality of carrier frequencies, wherein the demodulating the first modulated signal to obtain the pairing information includes: amplitude demodulating the first modulated signal to determine the carrier frequency; and determining the pairing frequency point according to the carrier frequency.

[0145] Specifically, the pairing frequency point can be one of a plurality of optional frequency points (for example, in a frequency point list), and the carrier can include a plurality of carrier frequencies, which can correspond to the plurality of optional frequency points one by one. Each carrier frequency corresponds to a time period. When the pairing frequency point is determined, the time period in which the carrier frequency corresponding to the pairing frequency point is located in the carrier can be amplitude modulated, and the carrier in other time periods remains unchanged, so that the modulated signal can be obtained. Since the modulated signal includes a plurality of time periods corresponding to a plurality of optional frequency points, and the carrier frequencies of the plurality of time periods are different, for different pairing frequency points, the amplitude of the corresponding time period in the carrier can be adjusted to a preset value, and the mapping relationship between the pairing frequency point and the amplitude does not need to be set in advance, so that the modulation process can be simplified. When the wireless microphone demodulates the modulated signal, the frequency point corresponding to the carrier frequency with the preset amplitude in the modulated signal can be determined as the pairing frequency point.

[0146] Optionally, when the pairing frequency point is determined, the time period in which the carrier frequency corresponding to the pairing frequency point is located in the carrier can be amplitude modulated, and only the modulated carrier corresponding to the time period is selected as the modulated signal, so that the efficiency of signal transmission can be improved.

[0147] According to an embodiment of the present application, the pairing information includes a pairing frequency point, wherein the demodulating the first modulated signal to obtain the pairing information includes: demodulating the first modulated signal to obtain at least one frequency in the first modulated signal; and determining the pairing frequency point according to the at least one frequency.

[0148] In an embodiment, a carrier frequency can be determined according to the pairing frequency point, and different pairing frequency points can correspond to different carrier frequencies. When the pairing frequency point is determined, the carrier is modulated so that the carrier frequency of the obtained modulated signal is the carrier frequency corresponding to the pairing frequency point, wherein the carrier frequency of the modulated signal is a fixed value. In this way, different pairing frequency points can be distinguished by the carrier frequency of the modulated signal. In this embodiment, the mapping relationship between the pairing frequency point and the carrier frequency can be set in advance. For example, the carrier frequency of the modulated signal corresponding to the pairing frequency point 400 MHz is 20 kHz, and the carrier frequency of the modulated signal corresponding to the pairing frequency point 450 MHz is 21 kHz. When the wireless microphone demodulates the modulated signal to determine that the carrier frequency of the modulated signal is 20 kHz, it can be determined that the corresponding pairing frequency point is 400 MHz.

[0149] Since the embodiment adjusts the frequency of the carrier according to the mapping relationship between the pairing frequency point and the carrier frequency, the carrier frequency of the modulated signal can be fixed, so that the modulated signal can be guaranteed to be simple enough, thereby improving the anti-interference ability of the modulated signal and ensuring the accuracy of the signal transmission process.

[0150] In another embodiment, a plurality of carrier frequencies can be determined according to the pairing frequency point, that is, the carrier frequency of the modulated signal after modulation is variable, and the change rule of the carrier frequency of the modulated signal corresponding to different pairing frequency points is different. In this way, different pairing frequency points can be distinguished by the change rule of the carrier frequency of the modulated signal. For example, the pairing frequency point is represented by a binary number, 1 in the binary number corresponds to a first carrier frequency, and 0 in the binary number corresponds to a second carrier frequency. After the wireless microphone demodulates the modulated signal, the change rule of the carrier frequency of the modulated signal can be determined, and the corresponding pairing frequency point can be determined.

[0151] Since the embodiment adjusts the carrier frequency of the carrier in different periods according to different numbers in the pairing frequency point, the type of pairing information that can be carried by the modulated signal can be significantly improved, and the efficiency of signal transmission can be improved. For example, the pairing frequency point is represented by an n-bit binary number, and the carrier of a fixed time length can have 2n n variations, that is, 2n n modulated signals can be obtained. 2n n modulated signals can correspond to 2n n pairing frequency points, so that the type of pairing information that can be carried by the modulated signal is significantly improved; and 2n nThe time length of the modulated signal is the same (for example, n seconds), which is relatively short, and thus the efficiency of signal transmission can be improved. For example, n=3, and the pairing frequency point is 101, where 1 corresponds to the first carrier frequency 21 kHz, and 0 corresponds to the second carrier frequency 20 kHz. Thus, the modulated signal corresponding to the pairing frequency point is composed of a 1-second 21-kHz waveband, a 1-second 20-kHz waveband, and a 1-second 21-kHz waveband.

[0152] In addition, since the embodiment adjusts the carrier frequency of the carrier in different time periods according to the change in the number in the pairing frequency point, the mapping relationship between the pairing frequency point and the carrier frequency does not need to be set in advance, and thus the pairing process can be simplified.

[0153] According to an embodiment of the present application, after the modulated signal is played through the loudspeaker, if the modulated signal is collected by the wireless microphone, and the communication frequency of the wireless communication module of the wireless microphone is adjusted to the frequency corresponding to the pairing information carried by the modulated signal, the wireless microphone can send data through the wireless communication module thereon. If the receiver receives the data, the pairing is successful. Here, the data sent by the wireless microphone can be a feedback signal corresponding to the successful configuration of the wireless communication module on the wireless microphone according to the pairing information, or can be data obtained by collecting the voice of the user, because the user generally tests the sound effect in advance by his own voice when using the wireless microphone.

[0154] According to an embodiment of the present application, the frequency of the first modulated signal is greater than or equal to a preset threshold.

[0155] According to an embodiment of the present application, the preset threshold is 20 kHz.

[0156] The frequency selection range of the modulated signal and the corresponding effect can be referred to the description in the pairing method (applied to the receiver) described above.

[0157] Figure 6 Fig. 6 shows a flowchart of a pairing method provided by another exemplary embodiment of the present application. Figure 6 The method is applied to a wireless microphone. As shown in Fig. 6, the pairing method comprises the following steps. Figure 6

[0158] 610: Collect a sound signal.

[0159] Specifically, the sound signal can be a modulated signal played by the receiver through the loudspeaker, or a voice of the user.

[0160] 620: Determine whether the wireless microphone is in a paired state.

[0161] If the wireless microphone is in an unpaired state, step 630 is performed.

[0162] ​630: demodulate the sound signal to obtain the pairing information.

[0163] Specifically, when the wireless microphone is in the unpaired state, it is indicated that the wireless microphone is in the pairing mode, and the wireless microphone can demodulate the collected sound signal, and if the demodulation is successful, the pairing information can be obtained. For example, the sound signal is a modulated signal played by the loudspeaker of the receiver, and the wireless microphone can demodulate the pairing information in the sound signal.

[0164] 640: configure the wireless communication module of the wireless microphone according to the pairing information.

[0165] Specifically, after obtaining the pairing information, the wireless microphone can configure the wireless communication module of the wireless microphone according to the pairing information, so that the wireless microphone and the corresponding receiver communicate at the same communication frequency.

[0166] The embodiment of the application provides a pairing method, which can realize automatic pairing between the wireless microphone and the receiver by collecting a sound signal and demodulating pairing information from the sound signal, thereby simplifying the pairing process. In addition, since the pairing method is realized by collecting a sound signal by the wireless microphone, the functions of the wireless microphone itself can be fully and reasonably utilized, and the pairing process does not need to be realized by an additional device, so that the complexity of the wireless microphone system can be reduced.

[0167] According to an embodiment of the application, if the wireless microphone is in the paired state, step 650 is performed.

[0168] 650: send the sound signal by using the wireless communication module.

[0169] Specifically, when the wireless microphone is in the paired state, it is indicated that the wireless microphone is in the working mode, and the wireless microphone can not process the collected sound signal, and directly send the sound signal to the corresponding receiver by the wireless communication module. Alternatively, the wireless microphone can perform appropriate compression processing on the sound signal, and send the compressed data to the corresponding receiver.

[0170] The embodiment can process the collected sound signal according to the pairing state of the wireless microphone, thereby improving the stability of the wireless microphone in the use process.

[0171] Figure 7 As shown in the figure, the pairing method provided by another exemplary embodiment of the application is shown. Figure 7 The embodiment is Figure 6 Examples of the embodiment, to avoid repetition, the same will not be repeated. As Figure 7 As shown in the figure, the pairing method includes the following contents.

[0172] 710: Collecting a sound signal.

[0173] 720: Judging whether the wireless microphone is in a paired state.

[0174] If the wireless microphone is in an unpaired state, step 730 is performed. If the wireless microphone is in a paired state, step 760 is performed.

[0175] 730: Judging whether a feature of the sound signal meets a preset condition.

[0176] If the feature of the sound signal meets the preset condition, step 740 is performed. If the feature of the sound signal does not meet the preset condition, step 770 is performed.

[0177] Specifically, the feature of the sound signal can be frequency or amplitude, etc., and correspondingly, the preset condition can be a frequency range, a frequency threshold, an amplitude range or an amplitude threshold, etc. of the sound signal. The specific preset condition can be set in advance as needed.

[0178] 740: Demodulating the sound signal to obtain pairing information.

[0179] For example, the feature of the sound signal (demodulated signal) played by the receiver through the loudspeaker is specific and meets the preset condition. If the feature of the sound signal collected by the wireless microphone meets the preset condition, it indicates that the sound signal is a demodulated signal for pairing, and thus the wireless microphone can demodulate the sound signal.

[0180] 750: Configuring the wireless communication module of the wireless microphone according to the pairing information.

[0181] 760: Sending the sound signal by using the wireless communication module.

[0182] 770: Discarding the sound signal.

[0183] Specifically, if the feature of the sound signal does not meet the preset condition, it indicates that the sound signal is not a demodulated signal for pairing, and thus the wireless microphone can discard (e.g., delete) the sound signal to avoid occupying memory.

[0184] The embodiment can demodulate the sound signal meeting the preset condition and discard the sound signal not meeting the preset condition by judging in advance whether the wireless microphone is in a paired state and further judging whether the feature of the sound signal meets the preset condition when the wireless microphone is in an unpaired state, so that memory can be saved and pairing efficiency can be improved.

[0185] According to an embodiment of the present application, the wireless microphone can include a microphone array composed of a plurality of microphone units, and different microphone units in the microphone array can be paired with different receivers to be applicable to more application scenarios. The pairing method between each microphone unit and the receiver in the embodiment can refer to the pairing method provided in any of the above embodiments.

In addition, since the modulated signal carrying the pairing information is played by the loudspeaker and received by the wireless microphone, the functions of the loudspeaker and the wireless microphone themselves can be fully and reasonably utilized, and the pairing process does not need to be realized by additional devices, thereby reducing the complexity of the wireless microphone system.
