In particular, during live streaming, users need to monitor the audio collected by each acquisition device in real time to ensure the quality of the live stream's audio; therefore, audio systems used in live streaming scenarios usually also include monitoring devices.

[0003] In related technologies, audio systems in live streaming scenarios typically use wired connections for audio acquisition and reception. However, this wired communication method results in a large number and tangled cables throughout the audio system. Therefore, designing a novel audio system has become an urgent technical challenge.

[0006] The wireless receiving module of the first microphone is used for wireless communication with the wireless transmitting module of the second microphone and the terminal, and receives the real-time audio signal of the second microphone and the control signal of the terminal through time-division receiving; the control module of the first microphone controls the transmission and reception of the corresponding real-time audio signal according to the control signal.

[0007] The wireless transmission module of the first microphone is used to communicate wirelessly with the wireless receiving module of the second microphone and the terminal, and transmits the real-time audio signal of the first microphone to the second microphone and the terminal in a time-division transmission manner.

[0008] The wireless receiving module of the second microphone is also used for wireless communication with the terminal, and receives the real-time audio signal from the first microphone and another control signal from the terminal through time-division reception; the control module of the second microphone controls the transmission and reception of the corresponding real-time audio signal according to the other control signal.

[0009] The wireless transmission module of the second microphone is also used for wireless communication with the terminal, and transmits the real-time audio signal of the second microphone to the first microphone and the terminal in a time-division transmission manner.

[0010] At least one monitoring device is used to communicate with at least one of the terminal, the first microphone, and the second microphone to enable real-time monitoring of the real-time audio signal from the first microphone and / or the real-time audio signal from the second microphone.

[0011] Secondly, this application provides a control method for real-time communication using multiple microphones; the control method includes the following steps:

[0012] The wireless receiving module of the first microphone communicates wirelessly with the wireless transmitting module of the second microphone and the terminal, and receives the real-time audio signal of the second microphone and the control signal of the terminal through time-division receiving.

[0013] The wireless transmitting module of the first microphone communicates wirelessly with the wireless receiving module of the second microphone and the terminal, and transmits the real-time audio signal of the first microphone to the second microphone and the terminal in a time-division transmission manner.

[0014] The wireless receiving module of the second microphone also communicates wirelessly with the terminal and receives the real-time audio signal from the first microphone and another control signal from the terminal through time-division reception.

[0015] The wireless transmission module of the second microphone also communicates wirelessly with the terminal and transmits the real-time audio signal of the second microphone to the first microphone and the terminal in a time-division transmission manner.

[0016] At least one monitoring device communicates with at least one of the terminal, the first microphone, and the second microphone to enable real-time monitoring of the real-time audio signal from the first microphone and / or the real-time audio signal from the second microphone.

[0017] Thirdly, this application provides a wireless microphone; the wireless microphone includes a wireless receiving module, a wireless transmitting module, and a control module for controlling the operation of the wireless receiving module and the wireless transmitting module;

[0018] The wireless receiver module of the wireless microphone is used to communicate wirelessly with another wireless transmitter module of another external wireless microphone and the terminal, and receives the real-time audio signal of the other wireless microphone and the control signal of the terminal through time-division reception; the control module of the wireless microphone controls the transmission and reception of the corresponding real-time audio signal according to the control signal.

[0019] The wireless transmitter module of the wireless microphone is used to communicate wirelessly with another wireless receiver module of another wireless microphone and the terminal, and to transmit the real-time audio signal of the wireless microphone to another wireless microphone and the terminal in a time-division multiplexing manner.

[0020] Compared to related technologies, the multi-microphone real-time communication audio system, control method, and wireless microphone in this application have the following advantages:

[0021] By designing independent control modules in the first and second microphones, the control module of the first microphone can independently control the destination of the real-time audio signal recorded by the microphone of the first microphone, and the control module of the second microphone can independently control the destination of the real-time audio signal recorded by the microphone of the second microphone. This can achieve better adaptation and use in scenarios such as live streaming, reduce the need for cables in live streaming scenarios, and optimize the environment of live streaming scenarios.

[0022] The wireless receiving and transmitting modules in the first microphone communicate wirelessly with the wireless receiving and transmitting modules in the second microphone, thus reducing the use of cables. The wireless receiving and transmitting modules in the first microphone also communicate wirelessly with the terminal, thus reducing the use of cables. The wireless receiving and transmitting modules in the second microphone also communicate wirelessly with the terminal, thus reducing the use of cables.

[0023] By designing wireless receiving, transmitting, and control modules in the first microphone and in the second microphone, when the real-time audio signals collected by the first and second microphones need to be transmitted to multiple monitoring devices, the real-time audio signals collected by the microphone core of the first microphone are transmitted to the wireless receiving module and the terminal of the second microphone via the wireless transmitting module of the first microphone in a time-division multiplexing manner. The real-time audio signals collected by the microphone core of the second microphone are transmitted to the wireless receiving module and the terminal of the first microphone via the wireless transmitting module of the second microphone in a time-division multiplexing manner. This design ensures that the real-time audio signals only need to undergo one wireless transmission between the first and second microphones, or between the first microphone and the terminal, or between the second microphone and the terminal, which can effectively reduce the latency of the monitoring devices and improve the monitoring effect.

[0035] The terms "first," "second," and "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects and not to describe a specific order. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0036] For example, audio systems used in scenarios such as live streaming, social chat, and film production typically include audio acquisition devices and audio receiving devices. In particular, during live streaming, users need to monitor the audio collected by each acquisition device in real time to ensure the quality of the live stream's audio; therefore, audio systems used in live streaming scenarios usually also include monitoring devices.

[0037] In related technologies, audio systems in live streaming scenarios typically use wired connections for audio acquisition and reception. This wired connection results in a large number and tangled web of cables throughout the audio system. Furthermore, the abundance of cables can lead to a poor user experience, especially in scenarios involving multiple live streamers. The wired connections between multiple audio acquisition and reception devices further exacerbate the problem, creating a cluttered and potentially dangerous situation. Therefore, designing a novel audio system has become a pressing technical challenge for the industry.

[0038] To address the above technical problems, this application provides an audio system for real-time communication using multiple microphones. Please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a schematic diagram of the framework structure of an audio system for real-time communication with multiple microphones in one embodiment of this application, as shown below. Figure 1 As shown, the multi-microphone real-time communication audio system includes a first microphone 10, a second microphone 20, a terminal 30, and at least one listening device 40.

[0039] The first microphone 10 can be a desktop microphone or lavalier microphone used by one or more people in scenarios such as live streaming, social chat, and film and television production.

[0040] The second microphone 20 can be a desktop microphone or lavalier microphone used by one or more people in scenarios such as live streaming, social chat, and film and television production. Specifically, the second microphone 20 is wirelessly connected to the first microphone 10, enabling the second microphone 20 to collect real-time audio signals and send them to the first microphone 10; the second microphone 20 is also wirelessly connected to the terminal 30, enabling the second microphone 20 to collect real-time audio signals and send them to the terminal 30.

[0042] The terminal 30 has multiple applications (such as apps, plugins, etc.) installed, including but not limited to voice-changing software, drivers, etc. For example, the first microphone 10 and / or the second microphone 20 collect real-time audio signals, and the voice-changing software is used to perform voice-changing processing on the real-time audio signals collected by the first microphone 10 and / or the second microphone 20 to obtain a voice-changing signal (those skilled in the art can use common voice-changing techniques in the field of microphone voice-changing control, which will not be elaborated here).

[0043] Please see Figure 2 , Figure 2 This is a schematic diagram of the terminal structure in one embodiment of this application, as shown below. Figure 2 As shown, terminal 30 includes memory 31, processor 32, network interface 33 and communication bus 34.

[0044] The memory 31 includes at least one type of readable storage medium. The at least one type of readable storage medium can be a non-volatile storage medium such as flash memory, hard disk, multimedia card, card-type memory, etc. In some embodiments, the readable storage medium can be an internal storage unit of the terminal 30, such as the hard disk of the terminal 30. In other embodiments, the readable storage medium can also be an external storage medium of the terminal 30, such as a plug-in hard disk, SmartMedia Card (SMC), Secure Digital (SD) card, Flash Card, etc., equipped on the terminal 30.

[0045] In this embodiment, the readable storage medium of memory 31 is typically used to store the program of the control method for multi-microphone real-time communication installed on terminal 30. Memory 31 can also be used to temporarily store data that has been output or will be output.

[0046] In some embodiments, processor 32 may be a central processing unit (CPU), microprocessor or other data processing chip, used to run program code stored in memory 31 or process data, such as executing a program for an audio system for real-time communication with multiple microphones.

[0047] The network interface 33 may include a standard wired interface or a wireless interface (such as a Wi-Fi interface), and is typically used to establish communication connections between the terminal 30 and other terminals.

[0048] The communication bus 34 is used to realize the connection and communication between the memory 31, the processor 32 and the network interface 33.

[0049] It should be noted that, Figure 2 Only a terminal 30 including a memory 31, a processor 32, a network interface 33, and a communication bus 34 is shown. However, those skilled in the art should understand that this does not constitute a limitation on the terminal 30. The terminal 30 may also include more or fewer components than shown, or combine certain components.

Optionally, the terminal 30 may also include radio frequency (RF) circuitry, etc., which will not be described in detail here.

[0054] like Figure 1As shown, the monitoring device 40 can be, for example, a monitoring headset or earpiece used by one or more people in scenarios such as live streaming, social chat, and film and television production. Specifically, the monitoring device 40 can communicate with at least one of the terminal 30, the first microphone 10, and the second microphone 20 via wired or wireless means, thereby enabling the monitoring device 40 to monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time. For example, the monitoring device 40 can communicate with the terminal 30 via wired or wireless means. In this case, the first microphone 10 and / or the second microphone 20 collect real-time audio signals and send them to the terminal 30. The terminal 30 then sends the real-time audio signals of the first microphone 10 and / or the second microphone 20 to the monitoring device 40 (specifically, the third monitoring device 43 described below) with which it communicates, allowing the user to monitor the real-time audio signals of the first microphone 10 and / or the second microphone 20 in real time through the monitoring device 40. For example, the monitoring device 40 can also be connected to the first microphone 10 (or the second microphone 20) via wired or wireless means. In this case, the first microphone 10 and / or the second microphone 20 collect real-time audio signals and send the real-time audio signals to the first microphone 10 (or the second microphone 20). The first microphone 10 (or the second microphone 20) sends the real-time audio signals of the first microphone 10 and / or the real-time audio signals of the second microphone 20 to the monitoring device 40 (specifically, the first monitoring device 41 or the second monitoring device 42 described below) connected to it, so that the user can monitor the real-time audio signals of the first microphone 10 and / or the second microphone 20 in real time through the monitoring device 40. For example, the monitoring device 40 can also be connected to the first microphone 10 and the second microphone 20 via wired or wireless means. In this case, the first microphone 10 and / or the second microphone 20 collect real-time audio signals and send the real-time audio signals to the first microphone 10 and the second microphone 20. The first microphone 10 sends its real-time audio signals and / or the real-time audio signals of the second microphone 20 to the monitoring device 40 (specifically, the first monitoring device 41 and the second monitoring device 42 described above) connected to it, so that the user can listen to the real-time audio signals of the first microphone 10 and / or the second microphone 20 in real time through the monitoring device 40. The second microphone 20 sends its real-time audio signals of the first microphone 10 and / or the second microphone 20 to the monitoring device 40 connected to it, so that the user can listen to the real-time audio signals of the first microphone 10 and / or the second microphone 20 in real time through the monitoring device 40.

[0055] The first microphone 10 includes a wireless receiving module 11, a wireless transmitting module 12, and a control module 13 for controlling the operation of the wireless receiving module 11 and the wireless transmitting module 12; the wireless receiving module 11 is electrically connected to the control module 13, and the wireless transmitting module 12 is electrically connected to the control module 13. The second microphone 20 includes a wireless receiving module 21, a wireless transmitting module 22, and a control module 23 for controlling the operation of the wireless receiving module 21 and the wireless transmitting module 22; the wireless receiving module 21 is electrically connected to the control module 23, and the wireless transmitting module 22 is electrically connected to the control module 23.

[0056] The wireless receiving module 11 of the first microphone 10 is used to wirelessly communicate with the wireless transmitting module 22 of the second microphone 20 to receive the real-time audio signal from the second microphone 20. At this time, the microphone of the second microphone 20 collects the real-time audio signal, and the control module 23 of the second microphone 20 processes the real-time audio signal and sends it wirelessly to the wireless receiving module 11 of the first microphone 10 via the wireless transmitting module 22. The wireless receiving module 11 of the first microphone 10 then sends the received real-time audio signal to the control module 13 of the first microphone 10. The control module 13 of the first microphone 10 then sends the real-time audio signal from the second microphone 20 to the monitoring device 40 (specifically, the first monitoring device 41 described below) that is communicatively connected to the first microphone 10, so that the user can monitor the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0057] The wireless transmitting module 12 of the first microphone 10 is used to wirelessly communicate with the wireless receiving module 21 of the second microphone 20 to transmit the real-time audio signal of the first microphone 10 to the second microphone 20. At this time, the microphone of the first microphone 10 collects the real-time audio signal, and the control module 13 of the first microphone 10 processes the real-time audio signal and transmits it wirelessly to the wireless receiving module 21 of the second microphone 20 through the wireless transmitting module 12. The wireless receiving module 21 of the second microphone 20 then transmits the received real-time audio signal to the control module 23 of the second microphone 20. The control module 23 of the second microphone 20 then transmits the real-time audio signal from the first microphone 10 to the monitoring device 40 (specifically the second monitoring device 42 described below) that is communicatively connected to the second microphone 20, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0058] The wireless receiving module 11 of the first microphone 10 is also used for wireless communication with the terminal 30 to receive control signals from the terminal 30. The control module 13 of the first microphone 10 then controls the transmission and reception of the corresponding real-time audio signal according to the control signal. It should be noted that both the first microphone 10 and the second microphone 20 are equipped with independent control modules 13 / 23. The terminal 30 can generate control signals by editing and send the control signals to the wireless receiving module 11 of the first microphone 10 through the standard Bluetooth protocol. The wireless receiving module 11 of the first microphone 10 then sends the control signals to the control module 13 of the first microphone 10, so that the control module 13 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the control signal.

[0059] For example, terminal 30 sends a control signal to wireless receiving module 11 of first microphone 10, and wireless receiving module 11 of first microphone 10 sends the control signal to control module 13 of first microphone 10. At this time, control module 13 of first microphone 10 can send the real-time audio signal from first microphone 10 itself to monitoring device 40 (first monitoring device 41 described below) that is communicatively connected to first microphone 10, so that the user can monitor the real-time audio signal of first microphone 10 in real time through monitoring device 40.

[0060] Alternatively, the control module 13 of the first microphone 10 may send the real-time audio signal from the second microphone 20 to the monitoring device 40 (the first monitoring device 41 described below) which is communicatively connected to the first microphone 10, so that the user can monitor the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0061] Alternatively, the control module 13 of the first microphone 10 may send the real-time audio signal from the first microphone 10 itself and the real-time audio signal from the second microphone 20 to the monitoring device 40 (the first monitoring device 41 described below) which is connected to the first microphone 10, so that the user can monitor the real-time audio signal of the first microphone 10 and the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0062] In this way, the control module 13 of the first microphone 10 can control the reception of the corresponding real-time audio signal according to the control signal.

[0063] At this time, the control module 13 of the first microphone 10 can send the real-time audio signal collected by the first microphone 10 to the monitoring device 40 (the second monitoring device 42 described below) which is connected to the second microphone 20, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0064] Alternatively, the control module 13 of the first microphone 10 may send the real-time audio signal collected by the first microphone 10 to the monitoring device 40 (the third monitoring device 43 described below) which is connected to the terminal 30, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0065] In this way, the control module 13 of the first microphone 10 can control the transmission of the corresponding real-time audio signal according to the control signal.

[0066] It should be noted that when the terminal 30 is a computer, the computer is equipped with a physical keyboard. The user can input, for example, "Ctrl+A" through the physical keyboard. At this time, the computer generates a control signal and sends the control signal to the wireless receiving module 11 of the first microphone 10 through the standard Bluetooth protocol. The wireless receiving module 11 of the first microphone 10 sends the control signal to the control module 13 of the first microphone 10, so that the control module 13 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the control signal.

[0067] When terminal 30 is a mobile phone, the mobile phone is equipped with a virtual keyboard. The user can input, for example, "Ctrl+B" through the virtual keyboard. At this time, the mobile phone generates a control signal and sends the control signal to the wireless receiving module 11 of the first microphone 10 through the standard Bluetooth protocol. The wireless receiving module 11 of the first microphone 10 sends the control signal to the control module 13 of the first microphone 10, so that the control module 13 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the control signal.

[0068] The wireless transmission module 12 of the first microphone 10 is also used for wireless communication with the terminal 30 to send the real-time audio signal of the first microphone 10 to the terminal 30. At this time, the microphone of the first microphone 10 collects the real-time audio signal, and the control module 13 of the first microphone 10 processes the real-time audio signal and sends it to the terminal 30 wirelessly through the wireless transmission module 12 of the first microphone 10. The terminal 30 then sends the real-time audio signal from the first microphone 10 to the monitoring device 40 (specifically the third monitoring device 43 described below) that is connected to the terminal 30, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0069] The wireless receiving module 11 of the first microphone 10 communicates wirelessly with the wireless transmitting module 22 of the second microphone 20 and the terminal 30, and receives the real-time audio signal from the second microphone 20 and the control signal from the terminal 30 through time-division multiplexing. Specifically, the real-time audio signal from the second microphone 20 and the control signal from the terminal 30 are received by the wireless receiving module 11 of the first microphone 10 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal from the second microphone 20 and the control signal from the terminal 30. For example, the wireless receiving module 11 of the first microphone 10 may include, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-sharing transmission and reception of audio data of different protocols; or KAGA FEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured by software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol).

[0070] The wireless transmitting module 12 of the first microphone 10 wirelessly communicates with the wireless receiving module 21 of the second microphone 20 and the terminal 30, and transmits the real-time audio signal of the first microphone 10 to the second microphone 20 and the terminal 30 in a time-division multiplexing manner. Specifically, the real-time audio signal of the first microphone 10 is transmitted by the wireless transmitting module 12 of the first microphone 10 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal from the first microphone 10 transmitted to the second microphone 20 and the real-time audio signal from the first microphone 10 transmitted to the terminal 30. For example, the wireless transmission module 12 of the first microphone 10 may include, but is not limited to, wireless modules based on the Abracon LTCC chip antenna series. This antenna series supports multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-sharing transmission and reception of audio data of different protocols; or the KAGA FEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured via software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol) in a time-sharing manner.

[0071] The wireless receiving module 21 of the second microphone 20 is also used for wireless communication with the terminal 30 to receive another control signal from the terminal 30. The control module 23 of the second microphone 20 then controls the transmission and reception of the corresponding real-time audio signal according to the other control signal. It should be noted that both the second microphone 20 and the first microphone 10 are equipped with independent control modules 23 / 13. The terminal 30 can generate another control signal by editing and send it to the wireless receiving module 21 of the second microphone 20 via the standard Bluetooth protocol. The wireless receiving module 21 of the second microphone 20 then sends the other control signal to the control module 23 of the second microphone 20, so that the control module 23 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the other control signal.

[0072] For example, terminal 30 sends another control signal to wireless receiving module 21 of second microphone 20, and wireless receiving module 21 of second microphone 20 sends another control signal to control module 23 of second microphone 20. At this time, control module 23 of second microphone 20 can send the real-time audio signal from second microphone 20 itself to monitoring device 40 (second monitoring device 42 described below) that is communicatively connected to second microphone 20, so that the user can monitor the real-time audio signal of second microphone 20 in real time through monitoring device 40.

[0073] Alternatively, the control module 23 of the second microphone 20 may also send the real-time audio signal from the first microphone 10 to the monitoring device 40 (the second monitoring device 42 described below) that is communicatively connected to the second microphone 20, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0074] Alternatively, the control module 23 of the second microphone 20 may send the real-time audio signal from the second microphone 20 itself and the real-time audio signal from the first microphone 10 to the monitoring device 40 (the second monitoring device 42 described below) which is connected to the second microphone 20, so that the user can monitor the real-time audio signal of the second microphone 20 and the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0075] In this way, the control module 23 of the second microphone 20 can control the reception of the corresponding real-time audio signal according to another control signal.

[0076] At this time, the control module 23 of the second microphone 20 can send the real-time audio signal collected by the second microphone 20 to the monitoring device 40 (the first monitoring device 41 described below) which is connected to the first microphone 10, according to another control signal, so that the user can monitor the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0077] The control module 23 of the second microphone 20 can also send the real-time audio signal collected by the second microphone 20 to the monitoring device 40 (the third monitoring device 43 described below) which is connected to the terminal 30 according to another control signal, so that the user can monitor the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0078] In this way, the control module 23 of the second microphone 20 can control the transmission of the corresponding real-time audio signal according to another control signal.

[0079] It should be noted that when the terminal 30 is a computer, the computer is equipped with a physical keyboard. The user can input, for example, "Ctrl+D" through the physical keyboard. At this time, the computer generates another control signal. The computer sends the other control signal to the wireless receiving module 21 of the second microphone 20 through the standard Bluetooth protocol. The wireless receiving module 21 of the second microphone 20 sends the other control signal to the control module 23 of the second microphone 20, so that the control module 23 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the other control signal.

[0080] When terminal 30 is a mobile phone, the mobile phone is equipped with a virtual keyboard. The user can input, for example, "Ctrl+E" through the virtual keyboard. At this time, the mobile phone generates another control signal. The mobile phone sends the other control signal to the wireless receiving module 21 of the second microphone 20 through the standard Bluetooth protocol. The wireless receiving module 21 of the second microphone 20 sends the other control signal to the control module 23 of the second microphone 20, so that the control module 23 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the other control signal.

[0081] The wireless transmission module 22 of the second microphone 20 is also used for wireless communication with the terminal 30 to send the real-time audio signal of the second microphone 20 to the terminal 30. At this time, the microphone of the second microphone 20 collects the real-time audio signal, and the control module 23 of the second microphone 20 processes the real-time audio signal and sends it to the terminal 30 wirelessly through the wireless transmission module 22 of the second microphone 20. The terminal 30 then sends the real-time audio signal from the second microphone 20 to the monitoring device 40 (specifically the third monitoring device 43 described below) that is connected to the terminal 30, so that the user can monitor the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0082] The wireless receiving module 21 of the second microphone 20 wirelessly communicates with the wireless transmitting module 12 of the first microphone 10 and the terminal 30, and receives the real-time audio signal of the first microphone 10 and another control signal of the terminal 30 through time-division multiplexing. Specifically, the real-time audio signal of the first microphone 10 and the other control signal of the terminal 30 are received by the wireless receiving module 21 of the second microphone 20 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal of the first microphone 10 and the other control signal of the terminal 30. For example, the wireless receiving module 21 of the second microphone 20 may include, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-division multiplexing of audio data for different protocols; or KAGA FEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured by software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol).

[0083] The wireless transmitting module 22 of the second microphone 20 wirelessly communicates with the wireless receiving module 11 of the first microphone 10 and the terminal 30, and transmits the real-time audio signal of the second microphone 20 to the first microphone 10 and the terminal 30 in a time-division multiplexing manner. Specifically, the real-time audio signal of the second microphone 20 is transmitted by the wireless transmitting module 22 of the second microphone 20 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal from the second microphone 20 transmitted to the first microphone 10 and the real-time audio signal from the second microphone 20 transmitted to the terminal 30. For example, the wireless transmission module 22 of the second microphone 20 may include, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-sharing transmission and reception of audio data of different protocols; or KAGA FEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured by software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol).

[0084] It should be noted that the time intervals between the two signals received by the wireless receiving module 11 minutes of the first microphone 10, the two signals transmitted by the wireless transmitting module 12 minutes of the first microphone 10, the two signals received by the wireless receiving module 21 minutes of the second microphone 20, and the two signals transmitted by the wireless transmitting module 22 minutes of the second microphone 20 are relatively short to ensure the synchronization of the real-time audio signals of the first microphone 10 and the second microphone 20 for real-time monitoring. Furthermore, the time intervals for different modules can be the same or different. The time interval can be, but is not limited to, 10 milliseconds to 30 milliseconds. For example, the specific value of the time interval can be, but is not limited to, 10 milliseconds, 15 milliseconds, 20 milliseconds, 25 milliseconds, or 30 milliseconds. In this embodiment, the time interval is 20 milliseconds.

[0085] The audio system based on the multi-microphone real-time communication in the embodiments of this application has the following beneficial effects:

[0086] By designing independent control modules 13 / 23 in the first microphone 10 and the second microphone 20, the control module 13 of the first microphone 10 can independently control the destination of the real-time audio signal recorded by the microphone of the first microphone 10, and the control module 23 of the second microphone 20 can independently control the destination of the real-time audio signal recorded by the microphone of the second microphone 20. This can achieve better adaptation and use in scenarios such as live streaming, reduce the need for cables in live streaming scenarios, and optimize the environment of live streaming scenarios.

[0087] The wireless receiving module 11 and wireless transmitting module 12 in the first microphone 10 are wirelessly connected to the wireless receiving module 21 and wireless transmitting module 22 in the second microphone 20, thus reducing the use of cables. The wireless receiving module 11 and wireless transmitting module 12 in the first microphone 10 are also wirelessly connected to the terminal 30, thus reducing the use of cables. The wireless receiving module 21 and wireless transmitting module 22 in the second microphone 20 are also wirelessly connected to the terminal 30, thus reducing the use of cables.

[0088] By designing a wireless receiving module 11, a wireless transmitting module 12, and a control module 13 in the first microphone 10, and a wireless receiving module 21, a wireless transmitting module 22, and a control module 23 in the second microphone 20, when the real-time audio signals collected by the first microphone 10 and the second microphone 20 need to be transmitted to multiple monitoring devices 40, the real-time audio signals collected by the first microphone 10 are transmitted to the wireless receiving module 21 of the second microphone 20 and the terminal 30 through the wireless transmitting module 12 of the first microphone 10 in a time-division manner, and the real-time audio signals collected by the second microphone 20 are transmitted to the wireless receiving module 11 of the first microphone 10 and the terminal 30 through the wireless transmitting module 22 of the second microphone 20 in a time-division manner. This design allows the real-time audio signals to undergo only one wireless transmission between the first microphone 10 and the second microphone 20, or between the first microphone 10 and the terminal 30, or between the second microphone 20 and the terminal 30, which can effectively reduce the latency of the monitoring devices 40 and improve the monitoring effect.

[0089] like Figure 1 As shown, the wireless receiving module 11 of the first microphone 10 communicates wirelessly with the wireless transmitting module 22 of the second microphone 20 to receive the real-time audio signal of the second microphone 20 in the first time period; the wireless receiving module 11 of the first microphone 10 communicates wirelessly with the terminal 30 to receive the control signal of the terminal 30 in the second time period.

[0090] The wireless transmitting module 12 of the first microphone 10 communicates wirelessly with the wireless receiving module 21 of the second microphone 20 to transmit the real-time audio signal of the first microphone 10 to the second microphone 20 in a third time period; the wireless transmitting module 12 of the first microphone 10 communicates wirelessly with the terminal 30 to transmit the real-time audio signal of the first microphone 10 to the terminal 30 in a fourth time period.

[0091] The wireless receiving module 21 of the second microphone 20 communicates wirelessly with the terminal 30 to receive another control signal from the terminal 3 during the fifth time period.

[0092] The wireless transmission module 22 of the second microphone 20 communicates wirelessly with the terminal 30 to transmit the real-time audio signal of the second microphone 20 to the terminal 30 during the sixth time period.

[0093] Among them, the first time period, the second time period, the third time period, the fourth time period, the fifth time period, and the sixth time period are different time periods; at this time, the wireless receiving module 11 of the first microphone 10, the wireless transmitting module 12 of the first microphone 10, the wireless receiving module 21 of the second microphone 20, and the wireless transmitting module 22 of the second microphone 20 work independently of each other.

[0094] The first and third time periods are the same as each other, and the second, fourth, fifth and sixth time periods are the same as each other; at this time, the wireless transmission module 12 of the first microphone 10 and the wireless transmission module 22 of the second microphone 20 work simultaneously, and the wireless receiving module 11 of the first microphone 10 and the wireless receiving module 21 of the second microphone 20 work simultaneously.

[0095] It should be noted that the time intervals between the first, second, third, fourth, fifth, and sixth time periods are relatively short to ensure the synchronization of the real-time audio signal from the first microphone 10 and the real-time audio signal from the second microphone 20 for real-time monitoring. The time interval can be, but is not limited to, 10-30 milliseconds. For example, the specific value of the time interval can be, but is not limited to, 10 milliseconds, 15 milliseconds, 20 milliseconds, 25 milliseconds, or 30 milliseconds. In this embodiment, the time interval is 20 milliseconds.

[0096] like Figure 1 As shown, the wireless receiving module 11 and the wireless transmitting module 12 of the first microphone 10 each include an integrated antenna, and the two integrated antennas are disposed on or inside the housing of the first microphone 10. The wireless receiving module 21 and the wireless transmitting module 22 of the second microphone 20 each include an integrated antenna, and the two integrated antennas are disposed on or inside the housing of the second microphone 20.

[0097] The integrated antenna of the wireless receiving module 11 / 21 serves as a receiving antenna, used to convert electromagnetic wave signals into electrical signals (i.e., the aforementioned real-time audio signals) and receive them; the integrated antenna of the wireless transmitting module 12 / 22 serves as a transmitting antenna, used to convert electrical signals (i.e., the aforementioned real-time audio signals) into electromagnetic wave signals and transmit them.

[0098] When the integrated antenna is mounted on the housing of the corresponding first microphone 10 or second microphone 20, it is considered an external integrated antenna design, which improves the signal transmission performance of the integrated antenna. The external integrated antenna can be a whip antenna (retractable or fixed to the housing of the first microphone 10 or second microphone 20) or a helical antenna (mounted on the top or bottom of the housing of the first microphone 10 or second microphone 20). The external integrated antenna can be fixedly connected to the housing of the first microphone 10 or second microphone 20 by, but is not limited to, threaded connection, snap-fit ​​fixing, or magnetic fixing.

[0099] When the integrated antenna is housed within the housing of the corresponding first microphone 10 or second microphone 20, it is a built-in integrated antenna design. This makes the first microphone 10 or second microphone 20 appear simple, easy to carry and use. The built-in integrated antenna can be a PCB antenna (the integrated antenna is directly printed on a printed circuit board), an LSR antenna (the antenna is engraved on the inner wall of the housing using laser engraving), or a flexible antenna (made of flexible material and can be fixed to the inner wall of the housing of the first microphone 10 or second microphone 20 by adhesive).

[0100] like Figure 1 As shown, at least one of the first microphone 10 and the second microphone 20 includes a microphone body having a receiver plug port and a wireless receiver for detaching from the receiver plug port. The wireless receiver includes at least one of a wireless receiving module 11 / 21 and a wireless transmitting module 12 / 22.

[0101] The microphone can be a single first microphone 10 comprising a microphone body and a wireless receiver, or a single second microphone 20 comprising a microphone body and a wireless receiver, or both the first microphone 10 and the second microphone 20 comprising a microphone body and a wireless receiver. The wireless receiver is detachably connected to the microphone body to achieve a separate design for the wireless receiver and the microphone body.

[0102] The microphone body can have one or two receiver plug ports.

[0103] For example, when the microphone body has only one receiver plug-in port, there is only one wireless receiver. This can be because both the wireless receiver module 11 / 21 and the wireless transmitter module 12 / 22 are integrated into the housing of this single wireless receiver (i.e., the wireless receiver includes the wireless receiver module 11 / 21 and the wireless transmitter module 12 / 22), or one of the wireless receiver module 11 / 21 and the wireless transmitter module 12 / 22 is integrated into the housing of this single wireless receiver, while the other of the wireless receiver module 11 / 21 and the wireless transmitter module 12 / 22 is integrated into the housing of the microphone body.

[0104] For example, when the microphone body has two receiver plug ports, there are two wireless receivers, and each wireless receiver is detachably connected to one receiver plug port of the microphone body. The wireless receiving module 11 / 12 is integrated into the housing of one of the wireless receivers, and the wireless transmitting module 12 / 22 is integrated into the housing of the other wireless receiver.

[0105] It should be noted that by designing at least one of the wireless receiving module 11 and the wireless transmitting module 12 within the housing of the wireless receiver, and making the wireless receiver and microphone body separate, when the wireless receiving module 11 and / or the wireless transmitting module 12 integrated on the wireless receiver are damaged, only the wireless receiver needs to be replaced, without replacing the entire first microphone 10, thus avoiding resource waste. This design differs from the integrated design where the wireless receiving module 11 and the wireless transmitting module 12 are directly integrated onto the first microphone 10. Similarly, by designing at least one of the wireless receiving module 21 and the wireless transmitting module 22 within the housing of the wireless receiver, and making the wireless receiver and microphone body separate, when the wireless receiving module 21 and / or the wireless transmitting module 22 integrated on the wireless receiver are damaged, only the wireless receiver needs to be replaced, without replacing the entire second microphone 20, thus avoiding resource waste. This design differs from the integrated design where the wireless receiving module 21 and the wireless transmitting module 22 are directly integrated onto the second microphone 20.

[0106] like Figure 1 As shown, the wireless receiving module 11 of the first microphone 10 is used to wirelessly communicate with the wireless transmitting module 22 of the second microphone 20 via a first 2.4G proprietary wireless communication protocol to receive the real-time audio signal from the second microphone 20. The first 2.4G proprietary wireless communication protocol is a wireless communication technology based on the 2.4GHz frequency band. It does not follow common communication standard protocols (such as WiFi, Bluetooth, etc.) but is a proprietary protocol developed by chip design companies according to specific user needs. The first 2.4G proprietary wireless communication protocol has advantages such as low latency, high transmission rate, long-distance transmission, and high degree of customization.

[0107] The wireless transmitting module 12 of the first microphone 10 is used to wirelessly communicate with the wireless receiving module 21 of the second microphone 20 via a second 2.4G proprietary wireless communication protocol to transmit real-time audio signals from the first microphone 10 to the second microphone 20. The second 2.4G proprietary wireless communication protocol is a wireless communication technology based on the 2.4GHz frequency band. It does not follow common communication standard protocols (such as WiFi, Bluetooth, etc.) but is a proprietary protocol developed by chip design companies according to specific user needs. The second 2.4G proprietary wireless communication protocol has advantages such as low latency, high transmission rate, long-distance transmission, and high degree of customization.

[0108] The wireless receiving module 11 of the first microphone 10 is also used to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol to receive control signals from the terminal 30. The standard Bluetooth communication protocol is a widely used wireless communication technology specification used to achieve wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has advantages such as low power consumption, wide compatibility, and short-range transmission. The standard Bluetooth communication protocol can include, but is not limited to, standard Bluetooth 5.1, standard Bluetooth 5.2, standard Bluetooth 5.3, standard Bluetooth 5.4, etc. By designing the wireless receiving module 11 of the first microphone 10 to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol, the control signals are effectively transmitted from the terminal 30 to the wireless receiving module 11 of the first microphone 10, so that the control module 13 of the first microphone 10 can control the transmission and reception of the corresponding real-time audio signals according to the control signals.

[0109] The wireless transmission module 12 of the first microphone 10 is also used to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol to transmit the real-time audio signal of the first microphone 10 to the terminal 30. The standard Bluetooth communication protocol is a widely used wireless communication technology specification used to achieve wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has advantages such as low power consumption, wide compatibility, and short-range transmission. The standard Bluetooth communication protocol can include, but is not limited to, standard Bluetooth 5.1, standard Bluetooth 5.2, standard Bluetooth 5.3, standard Bluetooth 5.4, etc. By designing the wireless transmission module 12 of the first microphone 10 to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol, the real-time audio signal of the first microphone 10 is effectively transmitted from the wireless transmission module 12 of the first microphone 10 to the terminal 30. The terminal 30 then sends the real-time audio signal from the first microphone 10 to the monitoring device 40 (the third monitoring device 43 described below), which is communicatively connected to the terminal 30, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0110] The wireless receiving module 21 of the second microphone 20 is also used to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol to receive another control signal from the terminal 30. The standard Bluetooth communication protocol is a widely used wireless communication technology specification used to achieve wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has advantages such as low power consumption, wide compatibility, and short-range transmission. The standard Bluetooth communication protocol can include, but is not limited to, standard Bluetooth 5.1, standard Bluetooth 5.2, standard Bluetooth 5.3, standard Bluetooth 5.4, etc. By designing the wireless receiving module 21 of the second microphone 20 to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol, another control signal is effectively transmitted from the terminal 30 to the wireless receiving module 21 of the second microphone 20, so that the control module 23 of the second microphone 20 can control the transmission and reception of the corresponding real-time audio signal according to the other control signal.

[0111] The wireless transmission module 22 of the second microphone 20 is also used to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol to transmit the real-time audio signal of the second microphone 20 to the terminal 30. The standard Bluetooth communication protocol is a widely used wireless communication technology specification used to achieve wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has advantages such as low power consumption, wide compatibility, and short-range transmission. The standard Bluetooth communication protocol can include, but is not limited to, standard Bluetooth 5.1, standard Bluetooth 5.2, standard Bluetooth 5.3, standard Bluetooth 5.4, etc. By designing the wireless transmission module 22 of the second microphone 20 to wirelessly communicate with the terminal 30 via the standard Bluetooth communication protocol, the real-time audio signal of the second microphone 20 is effectively transmitted from the wireless transmission module 22 of the second microphone 20 to the terminal 30. The terminal 30 then sends the real-time audio signal from the second microphone 20 to the monitoring device 40 (the third monitoring device 43 described below), which is communicatively connected to the terminal 30, so that the user can monitor the real-time audio signal of the second microphone 20 in real time through the monitoring device 40.

[0112] like Figure 1As shown, both the first microphone 10 and the second microphone 20 are desktop microphones. The first microphone 10 is used to collect the voice of user 1 to obtain a real-time audio signal. The first microphone 10 is communicatively connected to a monitoring device 40 (the first monitoring device 41 described below). User 1 can use the monitoring device 40 to monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time. The second microphone 20 is used to collect the voice of user 2 to obtain a real-time audio signal. The second microphone 20 is communicatively connected to a monitoring device 40 (the second monitoring device 42 described below). User 2 can use the monitoring device 40 to monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time. Both the first microphone 10 and the second microphone 20 are desktop microphones suitable for indoor scenarios such as two-person conversations, podcasts, interviews, and debates. The targeted independent monitoring design allows user 1 and user 2 to clearly obtain the content of each other's voices.

[0113] Both the first microphone 10 and the second microphone 20 are lavalier microphones. The first microphone 10 is used to collect the voice of user 1 to obtain a real-time audio signal. The first microphone 10 is communicatively connected to a monitoring device 40 (the first monitoring device 41 described below). User 1 can use the monitoring device 40 to monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time. The second microphone 20 is used to collect the voice of user 2 to obtain a real-time audio signal. The second microphone 20 is communicatively connected to a monitoring device 40 (the second monitoring device 42 described below). User 2 can use the monitoring device 40 to monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time. It can be understood that the lavalier microphone is worn on the collar of the user's clothing. Without removing the lavalier microphone, the relative position between the lavalier microphone and the user's lips remains unchanged. Therefore, the user can wear the lavalier microphone and move around within a certain space. At this time, the lavalier first microphone 10 can still effectively collect the voice emitted by user 1, and the lavalier second microphone 20 can still effectively collect the voice emitted by user 2.

[0114] like Figure 3As shown, the first microphone 10 is one of a desktop microphone and a lavalier microphone, and the second microphone 20 is the other of the same microphone. The first microphone 10 is used to collect the user's voice to obtain a real-time audio signal. The first microphone 10 is communicatively connected to a monitoring device 40 (as described below, the first monitoring device 41), allowing the user to monitor the real-time audio signal from the first microphone 10 and / or the real-time audio signal from the second microphone 20 in real time. The second microphone 20 is also used to collect the user's voice to obtain a real-time audio signal. The second microphone 20 is communicatively connected to a monitoring device 40 (as described below, the second monitoring device 42), allowing the user to monitor the real-time audio signal from the first microphone 10 and / or the real-time audio signal from the second microphone 20 in real time. It is understandable that in a single-person application scenario, the user can use a set of a lapel clip-on first microphone 10 and a desktop second microphone 20. When the user leaves the seat and moves away from the terminal 30, the user can record and listen in real time through the lapel clip-on first microphone 10. When the user returns to the seat and moves closer to the terminal 30, the user can record and listen in real time through the desktop second microphone 20.

[0115] like Figure 1 As shown, at least one monitoring device 40 is used for wired communication with at least one of the terminal 30, the first microphone 10, and the second microphone 20 to achieve real-time monitoring of the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20. By designing the monitoring device 40 to be connected to at least one of the terminal 30, the first microphone 10, and the second microphone 20 via wired communication, high-reliability, high-speed, and high-security transmission of the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 is achieved between the monitoring device 40 and the terminal 30, between the monitoring device 40 and the first microphone 10, and between the monitoring device 40 and the second microphone 20, with wide compatibility.

[0116] Specifically, at least one monitoring device 40 includes a first monitoring device 41, a second monitoring device 42, and a third monitoring device 43. The first microphone 10, the second microphone 20, and the terminal 30 all include audio interfaces. The first monitoring device 41 is plugged into the audio interface of the first microphone 10 to achieve real-time monitoring of the real-time audio signals of the first microphone 10 and / or the second microphone 20. The second monitoring device 42 is plugged into the audio interface of the second microphone 20 to achieve real-time monitoring of the real-time audio signals of the first microphone 10 and / or the second microphone 20. The third monitoring device 43 is plugged into the audio interface of the terminal 30 to achieve real-time monitoring of the real-time audio signals of the first microphone 10 and / or the second microphone 20. The specific type of audio interface may be, but is not limited to, a USB interface, a 3.5mm AUX interface, or an HDMI interface, etc. The first monitoring device 41 is connected to the audio interface of the first microphone 10, so that the user can monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time from the end where the first microphone 10 is located through the first monitoring device 41; the second monitoring device 42 is connected to the audio interface of the second microphone 20, so that the user can monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time from the end where the second microphone 20 is located through the second monitoring device 42; the third monitoring device 43 is connected to the audio interface of the terminal 30, so that the user can monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time from the end where the terminal 30 is located through the third monitoring device 43.

[0117] Specifically, the terminal 30 is also used to send selection signals to the first microphone 10, the second microphone 20 and the third listening device 43 to achieve selective listening to the first listening device 41, the second listening device 42 and the third listening device 43; selective listening includes real-time listening to the real-time audio signal of the first microphone 10, real-time listening to the real-time audio signal of the second microphone 20, and simultaneously real-time listening to the real-time audio signal of the first microphone 10 and the real-time audio signal of the second microphone 20.

[0118] For example, when terminal 30 sends a selection signal to the first microphone 10, the second microphone 20 and the third listening device 43, it can select the first listening device 41 to listen to the real-time audio signal of the first microphone 10 in real time, or it can select the first listening device 41 to listen to the real-time audio signal of the second microphone 20 in real time, or it can select the first listening device 41 to listen to the real-time audio signals of both the first microphone 10 and the second microphone 20 in real time.

[0119] For example, when terminal 30 sends a selection signal to the first microphone 10, the second microphone 20 and the third listening device 43, it can select the second listening device 42 to listen to the real-time audio signal of the first microphone 10 in real time, or it can select the second listening device 42 to listen to the real-time audio signal of the second microphone 20 in real time, or it can select the second listening device 42 to listen to the real-time audio signals of both the first microphone 10 and the second microphone 20 in real time.

[0120] For example, when terminal 30 sends a selection signal to the first microphone 10, the second microphone 20 and the third listening device 43, it can select the third listening device 43 to listen to the real-time audio signal of the first microphone 10 in real time, or it can select the third listening device 43 to listen to the real-time audio signal of the second microphone 20 in real time, or it can select the third listening device 43 to listen to the real-time audio signals of both the first microphone 10 and the second microphone 20 in real time.

[0121] It should be noted that, taking the first microphone 10 and the second microphone 20 as examples, when the terminal 30 is a computer, the computer is equipped with a physical keyboard. The user can input, for example, "Ctrl+M" through the physical keyboard. At this time, the computer generates a selection signal. The computer sends the selection signal to the wireless receiving module 11 (or 21) of the first microphone 10 (or the second microphone 20) through the standard Bluetooth protocol. The wireless receiving module 11 (or 21) of the first microphone 10 (or the second microphone 20) sends the selection signal to the control module 13 (or 23) of the first microphone 10 (or the second microphone 20), so that the control module 13 (or 23) of the first microphone 10 (or the second microphone 20) can selectively listen to the first listening device 41 and the second listening device 42 according to the selection signal.

[0122] When terminal 30 is a mobile phone, the phone is equipped with a virtual keyboard. Users can input, for example, "Ctrl+N" using the virtual keyboard. The phone then generates a selection signal, which is sent via standard Bluetooth protocol to the wireless receiving module 11 (or 21) of the first microphone 10 (or the second microphone 20). The wireless receiving module 11 (or 21) of the first microphone 10 (or the second microphone 20) then sends the selection signal to the control module 13 (or 23) of the first microphone 10 (or the second microphone 20). This allows the control module 13 (or 23) of the first microphone 10 (or the second microphone 20) to selectively monitor the first listening device 41 and the second listening device 42 based on the selection signal. In this design, terminal 30 achieves selective monitoring of the first listening device 41, the second listening device 42, and the third listening device 43 by sending selection signals to the first microphone 10, the second microphone 20, and the third listening device 43. This allows users to make reasonable choices according to their actual needs, making the design more versatile.

[0123] The following is a brief introduction to the user application scenarios for the above-mentioned multi-microphone real-time communication audio system:

[0124] The user establishes a wireless communication connection between the first microphone 10 and the second microphone 20, and the user establishes a wireless communication connection between the first microphone 10 and the terminal 30; the user establishes a wireless communication connection between the second microphone 20 and the terminal 30; the user establishes a wired communication connection between the first listening device 41 and the first microphone 10; the user establishes a wired communication connection between the second listening device 42 and the second microphone 20; and the user establishes a wired communication connection between the third listening device 43 and the terminal 30.

[0125] For single-user applications, a setup consisting of a lapel-style first microphone 10 and a desktop second microphone 20 can be used. When the user leaves their seat and moves away from the terminal 30, recording can be made using the lapel-style first microphone 10, and real-time monitoring can be performed via a first monitoring device 41 connected to the first microphone 10. When the user returns to their seat and moves closer to the terminal 30, recording can be made using the desktop second microphone 20, and real-time monitoring can be performed via a second monitoring device 42 connected to the second microphone 20. Alternatively, recording can be made using the desktop second microphone 20, and real-time monitoring can be performed via a third monitoring device 43 connected to the terminal 30. It should be noted that, as... Figure 3 As shown, based on a single-person application scenario, the monitoring switch from the lavalier first microphone 10 to the desktop second microphone 20, or from the desktop second microphone 20 to the lavalier first microphone 10, can be achieved through physical buttons or automatic control (such as infrared sensors, microwave radar, etc.).

[0126] Based on a multi-user application scenario, User 1 uses a first microphone 10, and User 2 uses a second microphone 20. The first microphone 10 is used to collect User 1's voice to obtain a real-time audio signal. User 1 can monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time through a first monitoring device 41 that is communicatively connected to the first microphone 10. User 1 can also monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time through a third monitoring device 43 that is communicatively connected to the terminal 30.

[0127] The second microphone 20 is used to collect the voice of the second user to obtain a real-time audio signal. The second user can monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time through the second monitoring device 42 which is connected to the second microphone 20. The second user can also monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time through the third monitoring device 43 which is connected to the terminal 30.

[0128] Of course, when user 1 uses the first listening device 41, which is connected to the first microphone 10, to conduct real-time listening, and user 2 uses the second listening device 42, which is connected to the second microphone 20, user 3 can also use the third listening device 43, which is connected to the terminal 30, to conduct real-time listening to the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20.

[0129] It should be noted that, regardless of whether it is a single-person application scenario or a multi-person application scenario as described above, the user can control the terminal 30 to send a control signal to the wireless receiving module 11 of the first microphone 10 according to actual needs, so that the control module 13 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the control signal; the user can control the terminal 30 to send another control signal to the wireless receiving module 21 of the second microphone 20 according to actual needs, so that the control module 23 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the other control signal; the user can control the terminal 30 to send selection signals to the wireless receiving module 11 of the first microphone 10, the wireless receiving module 21 of the second microphone 20, and the third listening device 43 according to actual needs, so as to achieve selective listening of the first listening device 41, the second listening device 42, and the third listening device 43.

[0130] Please see Figure 4 , Figure 4 This is a flowchart illustrating a control method for real-time multi-microphone communication in one embodiment of this application. Figure 2In the terminal 30 embodiment shown, when the processor 32 executes the program of the multi-microphone real-time communication control method stored in the memory 31, it implements... Figure 4 Steps S101-S105 are shown.

[0131] The following combination Figure 4 The steps S101-S105 of the control method for real-time communication with multiple microphones will be described in detail.

[0132] Step S101: The wireless receiving module 11 of the first microphone 10 communicates wirelessly with the wireless transmitting module 22 of the second microphone 20 and the terminal 30, and receives the real-time audio signal of the second microphone 20 and the control signal of the terminal 30 through time-division receiving.

[0133] Specifically, the first microphone 10 can be a desktop microphone or lavalier microphone used by one or more people in scenarios such as live streaming, social chat, and film and television production. The second microphone 20 can also be a desktop microphone or lavalier microphone used by one or more people in scenarios such as live streaming, social chat, and film and television production. Both the first microphone 10 and the second microphone 20 include a wireless receiving module 11 / 21, a wireless transmitting module 12 / 11, and a control module 13 / 23. In step S101, the microphone of the second microphone 20 acquires real-time audio signals. The control module 13 of the second microphone 20 processes the real-time audio signals and transmits them wirelessly to the wireless receiving module 11 of the first microphone 10 via the wireless transmitting module 22 of the second microphone 20. The wireless receiving module 11 of the first microphone 10 then transmits the received real-time audio signals to the control module 13 of the first microphone 10. The control module 13 of the first microphone 10 then transmits the real-time audio signals from the second microphone 20 to the monitoring device 40 (specifically, the first monitoring device 41 mentioned above) which is communicatively connected to the first microphone 10, so that the user can monitor the real-time audio signals of the second microphone 20 in real time through the monitoring device 40. The control module 13 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signals according to the control signals. Each of the first microphone 10 and the second microphone 20 is equipped with an independent control module 13 / 23. The terminal 30 can generate control signals through editing and send the control signals to the wireless receiving module 11 of the first microphone 10 via the standard Bluetooth protocol. The wireless receiving module 11 of the first microphone 10 then sends the control signals to the control module 13 of the first microphone 10, enabling the control module 13 of the first microphone 10 to control the transmission and reception of the corresponding real-time audio signals according to the control signals. For details regarding the control module 13 of the first microphone 10 controlling the transmission and reception of the corresponding real-time audio signals according to the control signals, please refer to the description in the audio system above; it will not be repeated here.

[0134] The wireless receiving module 11 of the first microphone 10, through a time-division multiplexing design, allows the real-time audio signal from the second microphone 20 and the control signal from the terminal 30 to be received by the wireless receiving module 11 of the first microphone 10 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal from the second microphone 20 and the control signal from the terminal 30. For example, the wireless receiving module 11 of the first microphone 10 can be, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-division multiplexing of audio data transmission and reception of different protocols; or KAGA FEIWKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured by software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol) in a time-division multiplexing manner.

[0135] Step S102: The wireless transmitting module 12 of the first microphone 10 communicates wirelessly with the wireless receiving module 21 of the second microphone 20 and the terminal 30, and transmits the real-time audio signal of the first microphone 10 to the second microphone 20 and the terminal 30 in a time-division multiplexing manner.

[0136] In step S102, the microphone of the first microphone 10 collects real-time audio signals. The control module 13 of the first microphone 10 processes the real-time audio signals and transmits them wirelessly to the wireless receiving module 21 of the second microphone 20 via the wireless transmitting module 12 of the first microphone 10. The wireless receiving module 21 of the second microphone 20 then transmits the received real-time audio signals to the control module 23 of the second microphone 20. The control module 23 of the second microphone 20 then transmits the real-time audio signals from the first microphone 10 to the monitoring device 40 (specifically the second monitoring device 42 mentioned above) that is communicatively connected to the second microphone 20, so that the user can monitor the real-time audio signals of the first microphone 10 in real time through the monitoring device 40. The microphone core of the first microphone 10 collects real-time audio signals. The control module 13 of the first microphone 10 processes the real-time audio signals and transmits them to the terminal 30 wirelessly via the wireless transmission module 12 of the first microphone 10. The terminal 30 then transmits the real-time audio signals from the first microphone 10 to the monitoring device 40 (specifically the third monitoring device 43 mentioned above) that is connected to the terminal 30, so that the user can monitor the real-time audio signals of the first microphone 10 in real time through the monitoring device 40.

[0137] The wireless transmission module 12 of the first microphone 10, through a time-division multiplexing design, allows the real-time audio signal from the first microphone 10 to be transmitted by the wireless transmission module 12 at different time segments. This avoids conflicts and interference between the real-time audio signal from the first microphone 10 transmitted to the second microphone 20 and the real-time audio signal from the first microphone 10 transmitted to the terminal 30. For example, the wireless transmission module 12 of the first microphone 10 can be, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-division multiplexing of audio data transmission and reception for different protocols; or the KAGA FEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication in the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured by software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol) in a time-division multiplexing manner.

[0138] Step S103: The wireless receiving module 21 of the second microphone 20 also communicates wirelessly with the terminal 30 and receives the real-time audio signal of the first microphone 10 and another control signal of the terminal 30 through time-division receiving.

[0139] Specifically, the control module 23 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to another control signal. Both the second microphone 20 and the first microphone 10 have independent control modules 23 / 13. The terminal 30 can generate another control signal through editing and send it to the wireless receiving module 21 of the second microphone 20 via the standard Bluetooth protocol. The wireless receiving module 21 of the second microphone 20 then sends the other control signal to the control module 23 of the second microphone 20, enabling the control module 23 of the second microphone 20 to control the transmission and reception of the corresponding real-time audio signal according to the other control signal. For details regarding the control module 23 of the second microphone 20 controlling the transmission and reception of the corresponding real-time audio signal according to the other control signal, please refer to the description in the audio system above; it will not be repeated here.

[0140] The wireless receiving module 21 of the second microphone 20 uses a time-division multiplexing design to ensure that the real-time audio signal from the first microphone 10 and another control signal from the terminal 30 are received by the wireless receiving module 21 of the second microphone 20 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal from the first microphone 10 and another control signal from the terminal 30. For example, the wireless receiving module 21 of the second microphone 20 can be, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can realize time-division multiplexing of audio data transmission and reception of different protocols; or the KAGAFEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured by software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol) in a time-division multiplexing manner.

[0141] Step S104: The wireless transmission module 22 of the second microphone 20 also communicates wirelessly with the terminal 30 and transmits the real-time audio signal of the second microphone 20 to the first microphone 10 and the terminal 30 in a time-division transmission manner.

[0142] In step S104, the microphone of the second microphone 20 collects real-time audio signals. The control module 23 of the second microphone 20 processes the real-time audio signals and transmits them to the terminal 30 wirelessly via the wireless transmission module 22 of the second microphone 20. The terminal 30 then transmits the real-time audio signals from the second microphone 20 to the monitoring device 40 (specifically the aforementioned third monitoring device 43) that is connected to the terminal 30, so that the user can monitor the real-time audio signals of the second microphone 20 in real time through the monitoring device 40.

[0143] The wireless transmission module 22 of the second microphone 20 employs a time-division multiplexing design, allowing the real-time audio signal from the second microphone 20 to be transmitted by the wireless transmission module 22 at different time segments. This avoids conflicts and interference between the real-time audio signal from the second microphone 20 transmitted to the first microphone 10 and the real-time audio signal from the second microphone 20 transmitted to the terminal 30. For example, the wireless transmission module 22 of the second microphone 20 can be, but is not limited to, Abracon LTCC chip antenna series wireless modules, which support multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz. Through dynamic frequency band switching technology, it can achieve time-division multiplexing of audio data transmission and reception for different protocols; or the KAGA FEI WKI611AA1 wireless module, which integrates Wi-Fi 6 and Bluetooth dual-mode functions, supports concurrent communication on the 2.4GHz and 5GHz frequency bands, supports real-time protocol processing, and can be configured via software to transmit and receive Bluetooth and private protocol data (such as a custom UHF audio transmission protocol) in a time-division multiplexing manner.

[0144] Step S105: At least one listening device 40 communicates with at least one of the terminal 30, the first microphone 10, and the second microphone 20 to enable real-time listening of the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20.

[0145] Specifically, the monitoring device 40 can communicate with at least one of the terminal 30, the first microphone 10, and the second microphone 20 via wired or wireless means, thereby enabling the monitoring device 40 to monitor the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 in real time.

[0146] In the multi-microphone real-time communication control method of this application embodiment, the real-time audio signal collected by the microphone of the first microphone 10 is transmitted to the wireless receiving module 21 of the second microphone 20 and the terminal 30 through the wireless transmitting module 12 of the first microphone 10 in a time-division manner. The real-time audio signal collected by the microphone of the second microphone 20 is transmitted to the wireless receiving module 11 of the first microphone 10 and the terminal 30 through the wireless transmitting module 22 of the second microphone 20 in a time-division manner. This design allows the real-time audio signal to undergo only one wireless transmission between the first microphone 10 and the second microphone 20, or between the first microphone 10 and the terminal 30, or between the second microphone 20 and the terminal 30, which can effectively reduce the latency of the monitoring device 40 and improve the monitoring effect.

[0147] Please see Figure 5 , Figure 5This is a schematic diagram of the frame structure of a wireless microphone in one embodiment of this application. The wireless microphone 50 includes a wireless receiving module 51, a wireless transmitting module 52, and a control module 53. The control module 53 is electrically connected to the wireless receiving module 51 to control the operation of the wireless receiving module 51, and the control module 53 is electrically connected to the wireless transmitting module 52 to control the operation of the wireless transmitting module 52.

[0148] The wireless receiver module 51 of the wireless microphone 50 is used to wirelessly communicate with another wireless transmitter module 62 of another external wireless microphone 60 and the terminal 70, and receives the real-time audio signal from the other wireless microphone 60 and the control signal from the terminal 70 through time-division multiplexing. The control module 53 of the wireless microphone 50 controls the transmission and reception of the corresponding real-time audio signal according to the control signal. At this time, the microphone of the other wireless microphone 60 collects the real-time audio signal, and the other control module 63 of the other wireless microphone 60 processes the real-time audio signal and sends it wirelessly to the wireless receiver module 51 of the wireless microphone 50 through the other wireless transmitter module 62 of the other wireless microphone 60. The wireless receiver module 51 of the wireless microphone 50 then sends the received real-time audio signal to the control module 53 of the wireless microphone 50. The control module 53 of the wireless microphone 50 then sends the real-time audio signal from the other wireless microphone 60 to the monitoring device 80 that is communicatively connected to the wireless microphone 50, so that the user can monitor the real-time audio signal of the other wireless microphone 60 in real time through the monitoring device 80. It should be noted that wireless microphone 50 and another wireless microphone 60 are equipped with independent control modules 53 and 63, respectively. Terminal 70 can generate control signals by editing and send them to the wireless receiving module 51 of wireless microphone 50 via the standard Bluetooth protocol. The wireless receiving module 51 of wireless microphone 50 then sends the control signals to the control module 53 of wireless microphone 50, enabling the control module 53 of wireless microphone 50 to control the transmission and reception of the corresponding real-time audio signals according to the control signals. For details regarding the specific transmission and reception of the corresponding real-time audio signals controlled by the control module 53 of wireless microphone 50 according to the control signals, please refer to the audio system described above; it will not be elaborated upon here.

[0149] The wireless receiver module 51 of the wireless microphone 50, through a time-division multiplexing design, allows the real-time audio signal from another wireless microphone 60 and the control signal from the terminal 70 to be received by the wireless receiver module 51 of the wireless microphone 50 at different time segments, thereby avoiding conflicts and interference between the real-time audio signal from the other wireless microphone 60 and the control signal from the terminal 70. For example, the wireless receiver module 51 of the wireless microphone 50 can be, but is not limited to, wireless modules from the Abracon LTCC chip antenna series, which supports multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz.

[0150] The wireless transmitter module 52 of the wireless microphone 50 is used to wirelessly communicate with another wireless receiver module 61 of another wireless microphone 60 and the terminal 70, and transmits the real-time audio signal of the wireless microphone 50 to the other wireless microphone 60 and the terminal 70 in a time-division multiplexing manner. At this time, the microphone of the wireless microphone 50 collects the real-time audio signal, and the control module 53 of the wireless microphone 50 processes the real-time audio signal and transmits it wirelessly to another wireless receiver module 61 of the other wireless microphone 60 through the wireless transmitter module 52. The other wireless receiver module 61 of the other wireless microphone 60 then transmits the received real-time audio signal to another control module 63 of the other wireless microphone 60. The other control module 63 of the other wireless microphone 60 then transmits the real-time audio signal from the wireless microphone 50 to the monitoring device 80 which is communicatively connected to the other wireless microphone 60, so that the user can monitor the real-time audio signal of the wireless microphone 50 in real time through the monitoring device 80. The microphone core of the wireless microphone 50 collects real-time audio signals. The control module 53 of the wireless microphone 50 processes the real-time audio signals and transmits them to the terminal 70 wirelessly via the wireless transmission module 52 of the wireless microphone 50.

[0151] The wireless transmitter module 52 of the wireless microphone 50 employs a time-division multiplexing design, allowing the real-time audio signal from the wireless microphone 50 to be transmitted by the wireless transmitter module 52 at different time segments. This avoids conflicts and interference between the real-time audio signal from the wireless microphone 50 transmitted to another wireless microphone 60 and the real-time audio signal from the wireless microphone 50 transmitted to the terminal 70. For example, the wireless transmitter module 52 of the wireless microphone 50 can be, but is not limited to, wireless modules from the Abracon LTCC chip antenna series. This antenna series supports multiple protocols such as Bluetooth, Wi-Fi, UWB, Sub-GHz, and LoRa, covering a wide frequency band from 2400MHz to 8.24GHz.

[0152] It should be noted that the wireless microphone 50 mentioned above can be a desktop microphone or lavalier microphone used by one or more people in scenarios such as live streaming, social chat, and film and television production.

[0153] In this embodiment, the real-time audio signal collected by the microphone of the wireless microphone 50 is transmitted by the wireless transmitting module 52 of the wireless microphone 50 to another wireless receiving module 61 of another wireless microphone 60 and the terminal 70 in a time-division multiplexing manner. This design allows the real-time audio signal to undergo only one wireless transmission between the wireless microphone 50 and the other wireless microphone 60, or between the wireless microphone 50 and the terminal 70, which can effectively reduce the latency of the monitoring device 80 and improve the monitoring effect.
