[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0015] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0017] The terms "first," "second," and "third," etc. in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0018] For example, audio systems used in live streaming, social chat, and film and television production typically include audio capture devices and audio receivers. In particular, during live streaming, users need to monitor the audio captured by each audio capture device in real time to ensure the quality of the live broadcast. Therefore, audio systems in live streaming scenarios typically include monitoring devices.

[0019] In related technologies, the audio system, audio capture equipment, and audio receiving equipment in live broadcast scenarios all use wired communication connections. However, this wired communication method results in numerous and cluttered wires throughout the entire audio system. Furthermore, the numerous wires can also lead to a poor user experience, especially in scenarios where multiple people are required to broadcast live. The wired communication connections of multiple sets of audio capture equipment and audio receiving equipment lead to a pile-up of wires throughout the audio system, posing certain safety risks. Therefore, designing a new audio system has become a technical issue that the industry urgently needs to address.

[0020] In order to solve the above technical problems, the present invention provides an audio system for real-time communication with multiple microphones. Figure 1 , Figure 1 This is a schematic diagram of the framework structure of an audio system for multi-microphone real-time communication in one embodiment of the present application. Figure 1As 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 monitoring device 40 .

[0021] The first microphone 10 can be a desktop microphone or a lavalier microphone, for example, used by one or more people in scenarios such as live broadcasts, social chats, and film and television production. Specifically, the first microphone 10 is wirelessly connected to the second microphone 20, so that the first microphone 10 can collect real-time audio signals and transmit the real-time audio signals to the second microphone 20; the first microphone 10 is wirelessly connected to the terminal 30, so that the first microphone 10 can collect real-time audio signals and transmit the real-time audio signals to the terminal 30.

[0022] The second microphone 20 can be, for example, a desktop microphone or a lavalier microphone used by one or more people in scenarios such as live broadcasts, social chats, and film and television production. Specifically, the second microphone 20 is wirelessly connected to the first microphone 10, allowing the second microphone 20 to collect real-time audio signals and transmit the real-time audio signals to the first microphone 10. The second microphone 20 is also wirelessly connected to the terminal 30, allowing the second microphone 20 to collect real-time audio signals and transmit the real-time audio signals to the terminal 30.

[0023] The terminal 30 may be an electronic device capable of performing operations such as single-person or multi-person live broadcasting, social chatting, and film and television production, and may specifically be, but not limited to, a tablet computer, a laptop computer, a desktop computer, an ultramobile personal computer (UMPC), a netbook, a mobile phone, and the like.

[0024] The terminal 30 has multiple applications (such as apps, plug-ins, etc.), including but not limited to voice changing software and driver programs. 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-changed signal (those skilled in the art can use common voice changing techniques in the field of microphone voice changing control, which will not be described in detail here).

[0025] See also Figure 2 , Figure 2 This is a schematic diagram of the structure of a terminal in an embodiment of the present application, such as Figure 2 As shown, the terminal 30 includes a memory 31 , a processor 32 , a network interface 33 and a communication bus 34 .

[0026] The memory 31 includes at least one type of readable storage medium. The at least one type of readable storage medium may be a non-volatile storage medium such as a flash memory, a hard disk, a multimedia card, or a card-type memory. In some embodiments, the readable storage medium may 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 may be an external memory of the terminal 30, such as a plug-in hard disk equipped in the terminal 30, a SmartMedia Card (SMC), a Secure Digital (SD) card, or a flash memory card.

[0027] In this embodiment, the readable storage medium of the memory 31 is generally used to store a program of a multi-microphone real-time communication control method installed in the terminal 30. The memory 31 can also be used to temporarily store data that has been output or is to be output.

[0028] In some embodiments, the processor 32 may be a central processing unit (CPU), a microprocessor, or other data processing chip, configured to execute program codes or process data stored in the memory 31 , such as a program for executing an audio system with multi-microphone real-time communication.

[0029] The network interface 33 may include a standard wired interface or a wireless interface (such as a WI-FI interface), and is generally used to establish a communication connection between the terminal 30 and other terminals.

[0030] The communication bus 34 is used to implement connection and communication among the memory 31 , the processor 32 and the network interface 33 .

[0031] It should be noted that Figure 2 Only the terminal 30 including the memory 31, the processor 32, the network interface 33 and the communication bus 34 is shown, but 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 in the figure, or combine certain components.

[0032] The terminal 30 may further include a user interface. The user interface may include an input unit such as a keyboard, a voice output device such as a speaker, etc. The user interface may also include a standard wired interface or a wireless interface.

[0033] Optionally, the terminal 30 may further include a display, which may also be referred to as a display screen or display unit. In some embodiments, this may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, or an organic light-emitting diode (OLED) touchscreen. The display is used to display information processed by the terminal 30 and to display a visual user interface.

[0034] Optionally, the terminal 30 further includes a touch sensor. The area provided by the touch sensor for a user to perform a touch operation is called a touch area. Furthermore, the touch sensor described herein may be a resistive touch sensor, a capacitive touch sensor, or the like. Furthermore, touch sensors include not only contact touch sensors but also proximity touch sensors, and the like. Furthermore, the touch sensor may be a single sensor or multiple sensors arranged, for example, in an array.

[0035] Furthermore, the display area of ​​the terminal 30 can be the same as or different from the touch sensor area. Optionally, the display and touch sensor can be stacked to form a touchscreen display, allowing the terminal 30 to detect user-triggered touch operations based on the touchscreen display. Optionally, the terminal 30 can also include radio frequency (RF) circuitry, etc., which will not be further described here.

[0036] like Figure 1As shown, the monitoring device 40 can be a monitoring headset or a monitoring earphone used by a single person or multiple people in scenarios such as live broadcasting, social chatting, and film and television production. Specifically, the monitoring device 40 can be connected to the terminal 30, the first microphone 10, and at least one of the second microphone 20 in a wired or wireless manner, so that the monitoring device 40 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. For example, the monitoring device 40 can be connected to the terminal 30 in a wired or wireless manner, and the first microphone 10 and / or the second microphone 20 collects the real-time audio signal and sends the real-time audio signal to the terminal 30. The terminal 30 sends the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 to the monitoring device 40, 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 through the monitoring device 40. For another example, the monitoring device 40 may be connected to the first microphone 10 (or the second microphone 20) in a wired or wireless manner. In this case, the first microphone 10 and / or the second microphone 20 collects real-time audio signals and sends 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 signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 to the monitoring device 40, allowing the user 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 through the monitoring device 40. For another example, the monitoring device 40 may be connected to the first microphone 10 and the second microphone 20 in a wired or wireless manner. In this case, the first microphone 10 and / or the second microphone 20 collects real-time audio signals and sends the real-time audio signals to the first microphone 10 and the second microphone 20. The first microphone 10 sends the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 to the monitoring device 40 connected thereto for communication, 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 through the monitoring device 40. The second microphone 20 sends the real-time audio signal of the first microphone 10 and / or the real-time audio signal of the second microphone 20 to the monitoring device 40 connected thereto for communication, 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 through the monitoring device 40.

[0037] The first microphone 10 includes a first wireless receiving module 11, a second wireless receiving module 12, a first wireless transmitting module 13, a second wireless transmitting module 14, and a control module 15 for controlling the operation of each of the above modules. The first wireless receiving module 11, the second wireless receiving module 12, the first wireless transmitting module 13, and the second wireless transmitting module 14 are all electrically connected to the control module 15. The second microphone 20 includes a first wireless receiving module 21, a second wireless receiving module 22, a first wireless transmitting module 23, and a second wireless transmitting module 24, and a control module 25 for controlling the operation of each of the above modules. The first wireless receiving module 21, the second wireless receiving module 22, the first wireless transmitting module 23, and the second wireless transmitting module 24 are all electrically connected to the control module 25.

[0038] The first wireless receiving module 11 of the first microphone 10 is used to wirelessly communicate with the first wireless transmitting module 23 of the second microphone 20 to receive the real-time audio signal of the second microphone 20. At this time, the microphone core of the second microphone 20 collects the real-time audio signal, and the control module 25 of the second microphone 20 processes the real-time audio signal and transmits it to the first wireless receiving module 11 of the first microphone 10 through the first wireless transmitting module 23 of the second microphone 20 in a wireless communication manner. The first wireless receiving module 11 of the first microphone 10 then transmits the received real-time audio signal to the control module 15 of the first microphone 10. The control module 15 of the first microphone 10 then transmits the real-time audio signal from the second microphone 20 to the monitoring device 40 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.

[0039] The first wireless transmitting module 13 of the first microphone 10 is used to wirelessly communicate with the first 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 core of the first microphone 10 collects the real-time audio signal, and the control module 15 of the first microphone 10 processes the real-time audio signal and transmits it to the first wireless receiving module 21 of the second microphone 20 via the first wireless transmitting module 13 of the first microphone 10 in a wireless communication manner. The first wireless receiving module 21 of the second microphone 20 then transmits the received real-time audio signal to the control module 25 of the second microphone 20, and the control module 25 of the second microphone 20 then transmits the real-time audio signal from the first microphone 10 to the monitoring device 40 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.

[0040] The second wireless receiving module 12 of the first microphone 10 is used to wirelessly communicate with the terminal 30 to receive a first control signal from the terminal 30. The control module 15 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal based on the first control signal. It should be noted that the control module 15 in the first microphone 10 and the control module 25 in the second microphone 20 are independently configured. The terminal 30 can generate a first control signal by editing and send the first control signal to the second wireless receiving module 12 of the first microphone 10 via the standard Bluetooth protocol. The second wireless receiving module 12 of the first microphone 10 sends the first control signal to the control module 15 of the first microphone 10, so that the control module 15 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal based on the first control signal.

[0041] For example, the terminal 30 sends a first control signal to the second wireless receiving module 12 of the first microphone 10, and the second wireless receiving module 12 of the first microphone 10 sends the first control signal to the control module 15 of the first microphone 10. At this time, the control module 15 of the first microphone 10 can send the real-time audio signal from the first microphone 10 itself to the monitoring device 40 (such as the first monitoring device 41 described below) that is communicatively connected to the first microphone 10 based on the first control signal, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0042] Alternatively, the control module 15 of the first microphone 10 may also send the real-time audio signal from the second microphone 20 to the monitoring device 40 that is communicatively connected to the first microphone 10 according to the first 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.

[0043] Alternatively, the control module 15 of the first microphone 10 can also 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 that is communicatively connected to the first microphone 10 according to the first control signal, 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.

[0044] In this way, the control module 15 of the first microphone 10 can control the reception of the corresponding real-time audio signal according to the first control signal.

[0045] At this time, the control module 15 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) that is communicatively connected to the second microphone 20 according to the first control signal, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0046] Alternatively, the control module 15 of the first microphone 10 can also send the real-time audio signal collected by the first microphone 10 to a monitoring device 40 (such as the third monitoring device 43 described below) that is communicatively connected to the terminal 30 according to the first control signal, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0047] In this way, the control module 15 of the first microphone 10 can control the sending of the corresponding real-time audio signal according to the first control signal.

[0048] It should be noted that when the terminal 30 is a computer, the computer is equipped with a physical keyboard, and the user can input "Ctrl+A" through the physical keyboard. At this time, the computer generates a first control signal, and the computer sends the first control signal to the second wireless receiving module 12 of the first microphone 10 through the standard Bluetooth protocol. The second wireless receiving module 12 of the first microphone 10 sends the first control signal to the control module 15 of the first microphone 10, so that the control module 15 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the first control signal.

[0049] When the terminal 30 is a mobile phone, the mobile phone is equipped with a virtual keyboard. The user can input "Ctrl+B" through the virtual keyboard. At this time, the mobile phone generates a first control signal, and the mobile phone sends the first control signal to the second wireless receiving module 12 of the first microphone 10 through the standard Bluetooth protocol. The second wireless receiving module 12 of the first microphone 10 sends the first control signal to the control module 15 of the first microphone 10, so that the control module 15 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the first control signal.

[0050] The second wireless transmission module 14 of the first microphone 10 is used to wirelessly communicate with the terminal 30 to transmit the real-time audio signal of the first microphone 10 to the terminal 30. At this time, the microphone core of the first microphone 10 collects the real-time audio signal, and the control module 15 of the first microphone 10 processes the real-time audio signal and transmits it to the terminal 30 via the second wireless transmission module 14 of the first microphone 10 in a wireless communication manner. The terminal 30 then transmits the real-time audio signal from the first microphone 10 to the monitoring device 40 that 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.

[0051] The second wireless receiving module 22 of the second microphone 20 is used to wirelessly communicate with the terminal 30 to receive a second control signal from the terminal 30. The control module 25 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal based on the second control signal. It should be noted that the control module 15 in the first microphone 10 and the control module 25 in the second microphone 20 are independently configured. The terminal 30 can generate a second control signal by editing and send the second control signal to the second wireless receiving module 22 of the second microphone 20 via the standard Bluetooth protocol. The second wireless receiving module 22 of the second microphone 20 sends the second control signal to the control module 25 of the second microphone 20, so that the control module 25 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal based on the second control signal.

[0052] For example, the terminal 30 sends the second control signal to the second wireless receiving module 22 of the second microphone 20, and the second wireless receiving module 22 of the second microphone 20 sends the second control signal to the control module 25 of the second microphone 20. At this time, the control module 25 of the second microphone 20 can send the real-time audio signal from the second microphone 20 itself to the monitoring device 40 that is communicatively connected to the second microphone 20 according to the second 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.

[0053] Alternatively, the control module 25 of the second microphone 20 may also send the real-time audio signal from the first microphone 10 to the monitoring device 40 that is communicatively connected to the second microphone 20 according to the second control signal, so that the user can monitor the real-time audio signal of the first microphone 10 in real time through the monitoring device 40.

[0054] Alternatively, the control module 25 of the second microphone 20 can also 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 that is communicatively connected to the second microphone 20 according to the second control signal, 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.

[0055] In this way, the control module 25 of the second microphone 20 can control the reception of the corresponding real-time audio signal according to the second control signal.

[0056] At this time, the control module 25 of the second microphone 20 can send the real-time audio signal collected by the second microphone 20 to the monitoring device 40 that is communicatively connected to the first microphone 10 according to the second 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.

[0057] Alternatively, the control module 25 of the second microphone 20 can also send the real-time audio signal collected by the second microphone 20 to the monitoring device 40 connected to the terminal 30 in communication according to the second 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.

[0058] In this way, the control module 25 of the second microphone 20 can control the sending of the corresponding real-time audio signal according to the second control signal.

[0059] It should be noted that when the terminal 30 is a computer, the computer is equipped with a physical keyboard, and the user can input "Ctrl+D" through the physical keyboard. At this time, the computer generates a second control signal, and the computer sends the second control signal to the second wireless receiving module 22 of the second microphone 20 through the standard Bluetooth protocol. The second wireless receiving module 22 of the second microphone 20 sends the second control signal to the control module 25 of the second microphone 20, so that the control module 25 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the second control signal.

[0060] When the terminal 30 is a mobile phone, the mobile phone is equipped with a virtual keyboard. The user can input "Ctrl+E" for example through the virtual keyboard. At this time, the mobile phone generates a second control signal, and the mobile phone sends the second control signal to the second wireless receiving module 22 of the second microphone 20 through the standard Bluetooth protocol. The second wireless receiving module 22 of the second microphone 20 sends the second control signal to the control module 25 of the second microphone 20, so that the control module 25 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the second control signal.

[0061] The second wireless transmission module 24 of the second microphone 20 is used to wirelessly communicate with the terminal 30 to transmit the real-time audio signal of the second microphone 20 to the terminal 30. At this time, the microphone core of the second microphone 20 collects the real-time audio signal, and the control module 25 of the second microphone 20 processes the real-time audio signal and transmits it to the terminal 30 via the second wireless transmission module 24 of the second microphone 20 in a wireless communication manner. The terminal 30 then transmits the real-time audio signal from the second microphone 20 to the monitoring device 40 that 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.

[0062] The multi-microphone real-time communication audio system based on the embodiments of the present application has the following beneficial effects: The control module 15 in the first microphone 10 and the control module 25 in the second microphone 20 are set independently of each other. The control module 15 of the first microphone 10 can independently control the direction of the real-time audio signal recorded by the microphone core of the first microphone 10, and the control module 25 of the second microphone 20 can independently control the direction of the real-time audio signal recorded by the microphone core of the second microphone 20. In this way, better adaptation and use effects can be achieved in scenes such as live broadcasts, reducing the demand for wires in live broadcast scenes and optimizing the environment of live broadcast scenes.

[0063] The first wireless receiving module 11 and the first wireless transmitting module 13 in the first microphone 10 are connected to the first wireless receiving module 21 and the first wireless transmitting module 23 in the second microphone 20 in a wireless communication manner, thereby reducing the use of wires; the second wireless receiving module 12 and the second wireless transmitting module 14 in the first microphone 10 are connected to the terminal 30 in a wireless communication manner, thereby reducing the use of wires; the second wireless receiving module 22 and the second wireless transmitting module 24 in the second microphone 20 are connected to the terminal 30 in a wireless communication manner, thereby reducing the use of wires.

[0064] By designing the first wireless receiving module 11, the first wireless transmitting module 13, the second wireless receiving module 12, the second wireless transmitting module 14 and the control module 15 in the first microphone 10, and designing the first wireless receiving module 21, the first wireless transmitting module 23, the second wireless receiving module 22, the second wireless transmitting module 24 and the control module 25 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 at the same time, the real-time audio signals collected by the first microphone 10 are sent to the first wireless receiving module 21 of the second microphone 20 through the first wireless transmitting module 13 of the first microphone 10, and the second microphone 20 collects the real-time audio signals. The real-time audio signal is sent to the first wireless receiving module 11 of the first microphone 10 through the first wireless sending module 23 of the second microphone 20, the real-time audio signal collected by the first microphone 10 is sent to the terminal 30 through the second wireless sending module 14 of the first microphone 10, and the real-time audio signal collected by the second microphone 20 is sent to the terminal 30 through the second wireless sending module 24 of the second microphone 20. This design allows the real-time audio signal to be transmitted wirelessly only once 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 delay of the monitoring device 40 and improve the monitoring effect.

[0065] like Figure 1As shown, the first wireless receiving module 11, the second wireless receiving module 12, the first wireless transmitting module 13, and the second wireless transmitting module 14 of the first microphone 10 each include an integrated antenna, and the four integrated antennas are disposed on or within the housing of the first microphone 10. The first wireless receiving module 21, the second wireless receiving module 22, the first wireless transmitting module 23, and the second wireless transmitting module 24 of the second microphone 20 each include an integrated antenna, and the four integrated antennas are disposed on or within the housing of the second microphone 20.

[0066] Among them, the integrated antennas of the first wireless receiving module 11 of the first microphone 10, the first wireless receiving module 21 of the second microphone 20, the second wireless receiving module 12 of the first microphone 10, and the second wireless receiving module 22 of the second microphone 20 serve as receiving antennas, which are used to convert electromagnetic wave signals into electrical signals (i.e., the above-mentioned real-time audio signals) and receive them; the integrated antennas of the first wireless transmitting module 13 of the first microphone 10, the first wireless transmitting module 23 of the second microphone 20, the second wireless transmitting module 14 of the first microphone 10, and the second wireless transmitting module 24 of the second microphone 20 serve as transmitting antennas, which are used to convert electrical signals (i.e., the above-mentioned real-time audio signals) into electromagnetic wave signals and transmit them.

[0067] When an integrated antenna is mounted on the housing of the corresponding first microphone 10 or second microphone 20, this constitutes an external integrated antenna design, which improves the integrated antenna's signal transmission performance. 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 via, but is not limited to, threaded connections, snap-on fastenings, or magnetic attachment.

[0068] When an integrated antenna is installed within the housing of the corresponding first microphone 10 or second microphone 20, this design utilizes a built-in integrated antenna. This design allows for a simple appearance and ease of portability for the first microphone 10 or second microphone 20. The built-in integrated antenna can be a PCB antenna (printed directly on a printed circuit board), an LSR antenna (laser-engraved onto the inner wall of the housing), or a flexible antenna (made of a flexible material and adhesively attached to the inner wall of the housing of the first microphone 10 or second microphone 20).

[0069] like Figure 1As 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 detachably connecting to the receiver plug port, and the wireless receiver includes at least one of the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20).

[0070] The first microphone 10 may include a microphone body and a wireless receiver, the second microphone 20 may include a microphone body and a wireless receiver, or both the first microphone 10 and the second microphone 20 may include a microphone body and a wireless receiver. The wireless receiver is detachably connected to the microphone body to achieve a separate design of the wireless receiver and the microphone body.

[0071] The number of the receiver plug-in ports of the microphone body can be one or more (more than two).

[0072] For example, when the number of the receiver plug-in port of the microphone body is one, the number of the wireless receiver is one at this time, and the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) are all integrated in the shell of the wireless receiver, that is, the wireless receiver includes the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20). Alternatively, parts of the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) are integrated into the housing of the wireless receiver, and the remaining parts of the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) are integrated into the housing of the microphone body.

[0073] For another example, when the number of receiver plug-in ports of the microphone body is multiple, the number of wireless receivers is multiple, and each wireless receiver is detachably connected to a receiver plug-in port of the microphone body. It can be the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) integrated in the housing of the multiple wireless receivers in a one-to-one or many-to-one manner, or it can be the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) integrated in the housing of the multiple wireless receivers in a one-to-one or many-to-one manner. The wireless receiving module 12 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) are partially integrated into the housing of the multiple wireless receivers in a one-to-one or many-to-one manner, and the remaining parts of the first wireless receiving module 11 of the first microphone 10 (or the first wireless receiving module 21 of the second microphone 20), the second wireless receiving module 12 of the first microphone 10 (or the second wireless receiving module 22 of the second microphone 20), the first wireless transmitting module 13 of the first microphone 10 (or the first wireless transmitting module 23 of the second microphone 20), and the second wireless transmitting module 14 of the first microphone 10 (or the second wireless transmitting module 24 of the second microphone 20) are integrated into the housing of the microphone body.

[0074] It should be noted that by designing at least one of the first wireless receiving module 11, the second wireless receiving module 12, the first wireless transmitting module 13, and the second wireless transmitting module 14 of the first microphone 10 within the housing of the wireless receiver, and the wireless receiver and the microphone body being separated, when the first wireless receiving module 11 and / or the second wireless receiving module 12 and / or the first wireless transmitting module 13 and / or the second wireless transmitting module 14 integrated in the wireless receiver are damaged, it is only necessary to replace the wireless receiver alone, without having to replace the entire first microphone 10, which would result in a waste of resources. This design is different from an integrated design in which the first wireless receiving module 11, the second wireless receiving module 12, the first wireless transmitting module 13, and the second wireless transmitting module 14 are directly integrated into the first microphone 10. Similarly, by designing at least one of the first wireless receiving module 21, the second wireless receiving module 22, the first wireless transmitting module 23, and the second wireless transmitting module 24 of the second microphone 20 within the housing of the wireless receiver, and the wireless receiver being separated from the microphone body, when the first wireless receiving module 21 and / or the second wireless receiving module 22 and / or the first wireless transmitting module 23 and / or the second wireless transmitting module 24 integrated in the wireless receiver are damaged, only the wireless receiver needs to be replaced separately, without having to replace the entire second microphone 20, which would result in a waste of resources. This design is different from an integrated design in which the first wireless receiving module 21, the second wireless receiving module 22, the first wireless transmitting module 23, and the second wireless transmitting module 24 are directly integrated into the second microphone 20.

[0075] like Figure 1 As shown, the first wireless receiving module 11 of the first microphone 10 is used to wirelessly communicate with the first wireless transmitting module 23 of the second microphone 20 via a first 2.4G private wireless communication protocol to receive real-time audio signals from the second microphone 20. The first 2.4G private wireless communication protocol is a wireless communication technology based on the 2.4GHz frequency band. It does not conform to universal communication standards (such as WiFi and Bluetooth), but is instead a proprietary protocol developed by chip design companies based on specific user needs. The first 2.4G private wireless communication protocol offers advantages such as low latency, high transmission rates, long-distance transmission, and a high degree of customization.

[0076] The first wireless transmitting module 13 of the first microphone 10 is configured to communicate wirelessly with the first wireless receiving module 21 of the second microphone 20 via a second 2.4G proprietary wireless communication protocol, thereby transmitting the real-time audio signal from the first microphone 10 to the second microphone 20. This second 2.4G proprietary wireless communication protocol is a wireless communication technology based on the 2.4GHz frequency band. It does not conform to universal communication standards (such as WiFi and Bluetooth), but is instead a proprietary protocol developed by chip design companies based on specific user needs. This second 2.4G proprietary wireless communication protocol offers advantages such as low latency, high transmission rates, long-distance transmission, and a high degree of customization.

[0077] The second wireless receiving module 12 of the first microphone 10 is used to communicate wirelessly with the terminal 30 through the standard Bluetooth communication protocol to receive the first control signal of the terminal 30. Among them, the standard Bluetooth communication protocol is a widely used wireless communication technology specification for realizing wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has the advantages of low power consumption, wide compatibility and short-range transmission. The standard Bluetooth communication protocol can include but is not limited to the standard 5.1 Bluetooth communication protocol, the standard 5.2 Bluetooth communication protocol, the standard 5.3 Bluetooth communication protocol, the standard 5.4 Bluetooth communication protocol and the like. By designing the second wireless receiving module 12 of the first microphone 10 to communicate wirelessly with the terminal 30 through the standard Bluetooth communication protocol, the first control signal is effectively transmitted from the terminal 30 to the second wireless receiving module 12 of the first microphone 10, so that the control module 15 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the first control signal.

[0078] The second wireless transmitting module 14 of the first microphone 10 is 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. Among them, the standard Bluetooth communication protocol is a widely used wireless communication technology specification for realizing wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has the advantages of low power consumption, wide compatibility and short-range transmission. The standard Bluetooth communication protocol can include but is not limited to the standard 5.1 Bluetooth communication protocol, the standard 5.2 Bluetooth communication protocol, the standard 5.3 Bluetooth communication protocol, the standard 5.4 Bluetooth communication protocol, etc. By designing the second wireless transmitting module 14 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 second wireless transmitting module 14 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 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.

[0079] The second wireless receiving module 22 of the second microphone 20 is used to communicate wirelessly with the terminal 30 through the standard Bluetooth communication protocol to receive the second control signal of the terminal 30. Among them, the standard Bluetooth communication protocol is a widely used wireless communication technology specification for realizing wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has the advantages of low power consumption, wide compatibility and short-range transmission. The standard Bluetooth communication protocol can include but is not limited to the standard 5.1 Bluetooth communication protocol, the standard 5.2 Bluetooth communication protocol, the standard 5.3 Bluetooth communication protocol, the standard 5.4 Bluetooth communication protocol and the like. By designing the second wireless receiving module 22 of the second microphone 20 to communicate wirelessly with the terminal 30 through the standard Bluetooth communication protocol, the second control signal is effectively transmitted from the terminal 30 to the second wireless receiving module 22 of the second microphone 20, so that the control module 25 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the second control signal.

[0080] The second wireless transmitting module 24 of the second microphone 20 is 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. Among them, the standard Bluetooth communication protocol is a widely used wireless communication technology specification for realizing wireless connection and data transmission between short-range devices. The standard Bluetooth communication protocol has the advantages of low power consumption, wide compatibility and short-range transmission. The standard Bluetooth communication protocol can include, but is not limited to, standard 5.1 Bluetooth communication protocol, standard 5.2 Bluetooth communication protocol, standard 5.3 Bluetooth communication protocol, standard 5.4 Bluetooth communication protocol, etc. By designing the second wireless transmitting module 24 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 second wireless transmitting module 24 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 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.

[0081] like Figure 1As shown, the first microphone 10 and the second microphone 20 are both desktop microphones. The first microphone 10 is used to collect the voice of user one to obtain a real-time audio signal. The first microphone 10 is communicatively connected to a monitoring device 40, and user one 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 two to obtain a real-time audio signal. The second microphone 20 is communicatively connected to a monitoring device 40, and user two 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 first microphone 10 and the second microphone 20 are both desktop microphones and can be used in indoor scenarios such as two-person conversations, podcasts, interviews, and debates. The targeted independent monitoring design enables user one and user two to clearly obtain each other's voice content.

[0082] 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 one to obtain a real-time audio signal. The first microphone 10 is communicatively connected to a monitoring device 40, allowing user one 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 two to obtain a real-time audio signal. The second microphone 20 is communicatively connected to the monitoring device 40, allowing user two 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 will 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 move around within a certain space while wearing the lavalier microphone and still effectively collect the voice of user one by the lavalier-type first microphone 10 and the voice of user two by the lavalier-type second microphone 20.

[0083] like Figure 3As shown, the first microphone 10 is either a desktop microphone or a lavalier microphone, and the second microphone 20 is the other of the two. 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, allowing the user 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 through the monitoring device 40. The second microphone 20 is used to collect the user's voice to obtain a real-time audio signal. The second microphone 20 is communicatively connected to the monitoring device 40, allowing the user 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 through the monitoring device 40. It will be appreciated that in a single-person application scenario, the user can use a combination of a lavalier-type first microphone 10 and a desktop-type second microphone 20. When the user leaves their seat and moves away from the terminal 30, the lavalier-type first microphone 10 can be used for recording and real-time monitoring. When the user returns to their seat and moves closer to the terminal 30, the desktop-type second microphone 20 can be used for recording and real-time monitoring.

[0084] like Figure 1 As shown, at least one monitoring device 40 is used to communicate with at least one of the terminal 30, the first microphone 10, and the second microphone 20 by wired communication 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 by wired communication, high-reliability, high-rate, 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, and with wide compatibility.

[0085] 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 enable 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. The second monitoring device 42 is plugged into the audio interface of the second microphone 20 to enable 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. The third monitoring device 43 is plugged into the audio interface of the terminal 30 to enable 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. The specific model of the audio interface can be, but is not limited to, a USB interface, a 3.5mm AUX interface, or an HDMI interface. 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 through the first monitoring device 41 from the end side where the first microphone 10 is located; 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 through the second monitoring device 42 from the end side where the second microphone 20 is located; 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 through the third monitoring device 43 from the end side where the terminal 30 is located.

[0086] Specifically, the terminal 30 is also used to send a third control signal to the first microphone 10, the second microphone 20 and the third monitoring device 43 to achieve selective monitoring of the first monitoring device 41, the second monitoring device 42 and the third monitoring device 43; selective monitoring includes real-time monitoring of the real-time audio signal of the first microphone 10, real-time monitoring of the real-time audio signal of the second microphone 20, and real-time monitoring of the real-time audio signal of the first microphone 10 and the real-time audio signal of the second microphone 20 at the same time.

[0087] For example, when the terminal 30 sends a third control signal to the first microphone 10, the second microphone 20 and the third monitoring device 43, the first monitoring device 41 can be selected to monitor the real-time audio signal of the first microphone 10 in real time, or the first monitoring device 41 can be selected to monitor the real-time audio signal of the second microphone 20 in real time, or the first monitoring device 41 can be selected to monitor the real-time audio signal of the first microphone 10 and the real-time audio signal of the second microphone 20 at the same time.

[0088] For another example, when the terminal 30 sends a third control signal to the first microphone 10, the second microphone 20 and the third monitoring device 43, the second monitoring device 42 can be selected to monitor the real-time audio signal of the first microphone 10 in real time, or the second monitoring device 42 can be selected to monitor the real-time audio signal of the second microphone 20 in real time, or the second monitoring device 42 can be selected to monitor the real-time audio signal of the first microphone 10 and the real-time audio signal of the second microphone 20 at the same time.

[0089] For another example, when the terminal 30 sends a third control signal to the first microphone 10, the second microphone 20 and the third monitoring device 43, the third monitoring device 43 can be selected to monitor the real-time audio signal of the first microphone 10 in real time, or the third monitoring device 43 can be selected to monitor the real-time audio signal of the second microphone 20 in real time, or the third monitoring device 43 can be selected to monitor the real-time audio signal of the first microphone 10 and the real-time audio signal of the second microphone 20 at the same time.

[0090] It should be noted that, taking the first microphone 10 as an example, when the terminal 30 is a computer, the computer is equipped with a physical keyboard, and the user can input "Ctrl+M" through the physical keyboard. At this time, the computer generates a third control signal, and the computer sends the third control signal to the second wireless receiving module 12 of the first microphone 10 through the standard Bluetooth protocol. The second wireless receiving module 12 of the first microphone 10 sends the third control signal to the control module 15 of the first microphone 10, so that the control module 15 of the first microphone 10 selects the first monitoring device 41 according to the third control signal to realize 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.

[0091] When terminal 30 is a mobile phone equipped with a virtual keyboard, the user can use the virtual keyboard to input, for example, "Ctrl+N." The mobile phone then generates a third control signal, which is then transmitted via the standard Bluetooth protocol to the second wireless receiving module 12 of the first microphone 10. The second wireless receiving module 12 of the first microphone 10 then transmits the third control signal to the control module 15 of the first microphone 10, causing the control module 15 of the first microphone 10 to select the first monitoring device 41 based on the third control signal 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. In this design, terminal 30 selectively monitors the first monitoring device 41, the second monitoring device 42, and the third monitoring device 43 by transmitting the third control signal to the first microphone 10, the second microphone 20, and the third monitoring device 43. This allows users to make reasonable choices based on their actual needs, resulting in greater applicability.

[0092] The following briefly introduces the user application scenarios of the multi-microphone real-time communication audio system mentioned above: The user establishes a communication connection between the first microphone 10 and the second microphone 20 wirelessly, and the user establishes a communication connection between the first microphone 10 and the terminal 30 wirelessly; the user establishes a communication connection between the second microphone 20 and the terminal 30 wirelessly; the user establishes a communication connection between the first monitoring device 41 and the first microphone 10 via a wired manner; the user establishes a communication connection between the second monitoring device 42 and the second microphone 20 via a wired manner; the user establishes a communication connection between the third monitoring device 43 and the terminal 30 via a wired manner.

[0093] Based on a single-person application scenario, the user can use a set of a first lavalier microphone 10 and a second desktop microphone 20. When the user leaves his seat and is far away from the terminal 30, the user can record through the first lavalier microphone 10 and monitor in real time through the first monitoring device 41 that is connected to the first microphone 10 in communication; when the user returns to his seat and approaches the terminal 30, the user can record through the second desktop microphone 20 and monitor in real time through the second monitoring device 42 that is connected to the second microphone 20 in communication, or can record through the second desktop microphone 20 and monitor in real time through the third monitoring device 43 that is connected to the terminal 30 in communication. It should be noted that, if Figure 3 As shown, based on a single-person application scenario, the monitoring switch from the first lavalier microphone 10 to the second desktop microphone 20, or the monitoring switch from the second desktop microphone 20 to the first lavalier microphone 10, can be achieved through physical buttons or automatic control (such as infrared sensors, microwave radars, etc.).

[0094] Based on a multi-person 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 the voice of user 1 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 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 communicatively connected to the terminal 30.

[0095] The second microphone 20 is used to collect the voice of user 2 to obtain a real-time audio signal. User 2 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 second monitoring device 42 that is communicatively connected to the second microphone 20. User 2 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.

[0096] Of course, when user one uses the first monitoring device 41 connected to the first microphone 10 for real-time monitoring, and user two uses the second monitoring device 42 connected to the second microphone 20 for real-time monitoring, user three can also use the third monitoring device 43 connected to the terminal 30 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.

[0097] It should be noted that, regardless of the above-mentioned single-person application scenario or the above-mentioned multi-person application scenario, the user can control the terminal 30 to send a first control signal to the second wireless receiving module 12 of the first microphone 10 according to actual needs, so that the control module 15 of the first microphone 10 controls the transmission and reception of the corresponding real-time audio signal according to the first control signal; the user can control the terminal 30 to send a second control signal to the second wireless receiving module 22 of the second microphone 20 according to actual needs, so that the control module 25 of the second microphone 20 controls the transmission and reception of the corresponding real-time audio signal according to the second control signal; the user can control the terminal 30 to send a third control signal to the second wireless receiving module 12 of the first microphone 10, the second wireless receiving module 22 of the second microphone 20 and the third monitoring device 43 according to actual needs, so as to realize selective monitoring of the first monitoring device 41, the second monitoring device 42 and the third monitoring device 43.
