[0055] Reference Figure 1 , Figure 1 This is a schematic diagram of the audio co-channel playback device structure in the hardware operating environment involved in the embodiments of the present invention.

The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.
[0057] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on audio co-channel playback devices and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0058] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and an audio co-channel playback program.
[0059] exist Figure 1In the audio co-channel playback device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the audio co-channel playback device of the present invention can be set in the audio co-channel playback device, and the audio co-channel playback device calls the audio co-channel playback program stored in the memory 1005 through the processor 1001 and executes the audio co-channel playback method provided in the embodiment of the present invention.
[0060] This invention provides an audio co-channel playback method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of an audio co-channel playback method according to the present invention.
[0061] In this embodiment, the audio co-channel playback method is applied to a terminal device; the audio co-channel playback method includes the following steps:
[0062] Step S10: Receive initial audio signaling transmitted from at least one microphone.
[0063] It should be noted that the execution subject of the method in this embodiment can be a device with data transmission and data processing functions, such as a terminal device or a control computer, or other devices with the same or similar functions. This embodiment does not impose specific limitations on this. In this embodiment and the following embodiments, a terminal device will be used as an example for explanation.
[0064] In this embodiment, the terminal device is connected to multiple microphones, receives audio signals from the multiple microphones through a receiver, and plays these audio signals through a playback device. In traditional technology, whenever the terminal device connects to an additional microphone, an additional communication channel needs to be set up in the terminal device to avoid audio confusion when multiple microphones collect sound at the same time.
[0065] In specific implementation, refer to Figure 3 The receiver primarily consists of a CPU, an audio wireless receiving module, an audio processing module, and a communication wireless transmitting / receiving module. The CPU is mainly used to set the operating parameters of each module within the receiver and to communicate with the microphone's internal CPU via the Wi-Fi protocol to set the operating parameters of the microphone's internal modules. The audio wireless receiving module receives wireless audio signals output from the microphone with audio transmission enabled. The audio processing module performs gain control, frequency response processing, and other processing on the audio signals output from the audio wireless receiving module. The communication wireless transmitting / receiving module uses the Wi-Fi protocol for bidirectional communication between the CPUs within the receiver and the microphone.
[0066] It is worth noting that the initial audio signaling refers to the data transmission signaling obtained after the microphone encapsulates or modulates the received audio signal according to a preset data format. The initial audio signaling includes the volume information of the audio signal collected by the corresponding microphone, the audio collection time, and the audio duration, etc. This embodiment does not impose specific limitations on this.
[0067] In the specific implementation, refer to Figure 4 , Figure 4 This is a block diagram of audio co-channel playback control logic. The initial audio signaling transmitted by each microphone can be received via WiFi communication between the microphone and the terminal device. However, the audio transmission between the microphone and the terminal device is carried out through a specific communication channel, and the two do not interfere with each other.
[0068] Step S20: Compare each initial audio signaling signal with a preset volume comparison model to obtain the target audio signaling signal.
[0069] It should be noted that the preset volume comparison model is used to compare the volume information contained in the initial audio signaling transmitted by each microphone via WiFi, so as to eliminate audio signals that are too quiet or too loud, thereby determining the audio signal with a suitable volume, and then controlling the corresponding microphone to transmit the audio signal to achieve audio playback.
[0070] It should be understood that the preset volume comparison model can be a control model based on a deep neural network algorithm to determine the audio signal to be played based on the audio volume, audio duration, and audio acquisition time.
[0071] Furthermore, in order to accurately determine the audio signal to be played and control the corresponding microphone to transmit the audio signal, the step of comparing each initial audio signal with a preset volume comparison model to obtain the target audio signal includes:
[0072] Extract volume information and audio duration from each initial audio signaling;
[0073] The initial audio signaling is filtered based on the volume information and the audio duration to obtain the target audio signaling;
[0074] The volume information is compared by a preset volume comparison model to determine the extreme values of the volume levels.
[0075] Determine the target audio signaling corresponding to the extreme value of the volume level in the initial audio signaling.
[0076] It is understood that the volume information in the initial audio signaling refers to the volume level after processing by each microphone, and its unit can be decibels or other units that can represent volume level. This embodiment does not impose specific restrictions on this.
[0077] In practice, for some microphones, the audio they capture may have a suitable volume, but the duration is short, making it invalid audio. It is necessary to block audio with short duration.
[0078] Further, the filtering of each initial audio signaling based on the volume information and the audio duration includes:
[0079] Acquire historical volume information of each initial audio signal within a preset time interval;
[0080] Determine the volume difference between the historical volume information and the volume information;
[0081] Initial audio signaling with a volume difference greater than a preset volume threshold or an audio duration less than a preset duration is excluded.
[0082] In specific implementation, a volume difference greater than a preset volume threshold means that the volume information collected within a certain time interval suddenly increases or decreases. In this case, the collected volume will be determined to be abnormal audio. For example, if the volume difference between the historical volume information of an initial audio signal and the volume information is greater than 20 decibels, or the duration of the audio is less than 0.5 seconds, it indicates that the initial audio signal is very likely to be noise.
[0083] Step S30: Generate an audio transmission command based on the target audio signaling, and send the audio transmission command to the microphone corresponding to the target audio command so that the microphone can feed back an audio signal.
[0084] It should be noted that after determining the audio signal that meets the playback conditions, the microphone that needs to be transmitted is determined according to the target audio signaling, the identification code of the corresponding microphone is determined, and then an audio transmission command is generated. Based on the identification code contained in the audio transmission command, the signal is transmitted to the target microphone via WiFi so that the microphone can feed back the complete audio signal it has collected.
[0085] Step S40: Perform audio processing on the audio signal and forward the processed audio signal to an external playback device for audio playback.
[0086] In practice, the audio processing of the audio signal collected by the microphone can include demodulation, amplification, digital-to-analog conversion, and noise reduction. This embodiment does not impose any specific limitations on this.
[0087] Further, the audio processing of the audio signal includes:
[0088] Demodulate the audio signal;
[0089] The demodulated audio signal is amplified to obtain the amplified audio signal.
[0090] The amplified audio signal is converted from digital to analog.
[0091] In a practical implementation, the microphone can feed back audio signals by enabling a UHF or VHF communication channel between the microphone and the terminal device, allowing the audio signal to be transmitted to the terminal device via the UHF or VHF communication channel, so that the terminal device can then forward it to an external playback device.
[0092] The external playback device can be a speaker, a loudspeaker, or other sound transmission device, and this embodiment does not impose specific limitations on it.
[0093] This embodiment discloses an audio co-channel playback method applied to a terminal device. The method includes: receiving initial audio signaling transmitted from at least one microphone; comparing each initial audio signaling using a preset volume comparison model to obtain a target audio signaling; generating an audio transmission command based on the target audio signaling and sending the audio transmission command to the microphone corresponding to the target audio command, so that the microphone feeds back an audio signal; processing the audio signal and forwarding the processed audio signal to an external playback device for audio playback. This embodiment determines the microphone that needs to be connected by comparing the audio signaling transmitted from each microphone, and then controls that microphone to connect to the terminal device through a preset communication channel. Simultaneously, it prohibits other microphones from occupying the preset communication channel, thereby achieving co-channel connection and playback of audio collected by multiple microphones. This avoids the high cost associated with setting up communication channels corresponding to the number of microphones in existing technologies.

This avoids the high cost associated with setting up communication channels corresponding to the number of microphones in existing technologies.
[0095] Reference Figure 5 , Figure 5 This is a structural block diagram of the first embodiment of the audio co-channel playback device of the present invention.
[0096] like Figure 5 As shown, the audio co-channel playback device proposed in this embodiment of the invention includes:
[0097] The signaling receiving module 10 is used to receive initial audio signaling transmitted from at least one microphone.
[0098] The volume comparison module 20 is used to compare each initial audio signaling through a preset volume comparison model to obtain the target audio signaling.
[0099] The microphone control module 30 is used to generate an audio transmission command according to the target audio signaling, and send the audio transmission command to the microphone corresponding to the target audio command, so that the microphone can feed back an audio signal.
[0100] The audio processing module 40 is used to process the audio signal and forward the processed audio signal to an external playback device for audio playback.
[0101] refer to Figure 6 , Figure 6 This is a flowchart illustrating a second embodiment of an audio co-channel playback method according to the present invention.
[0102] Based on the first embodiment described above, in this embodiment, the audio co-channel playback method is applied to an audio acquisition device;
[0103] The audio co-channel playback method includes:
[0104] Step S10: When an audio signal is acquired, determine the volume level and duration of the audio signal.
[0105] It should be noted that the subject of execution of the method in this embodiment refers to an audio acquisition device, such as a microphone or a sound acquisition device. In this embodiment and the following embodiments, a microphone will be used as an example for explanation.
[0106] It is worth noting that after the microphone collects external audio signals, it will first extract the volume information and duration of the collected audio signals in order to generate audio signaling for the terminal device to judge noise.
[0107] In the specific implementation, the internal structure block diagram of the microphone used in this embodiment can be referred to Figure 7 There are two communication channels between the microphone and the terminal device: a WiFi channel and a UHF / VHF communication channel. The WiFi communication channel is used to transmit signaling and control commands between the microphone and the terminal device, and the transmitted data does not require a dedicated communication interface and can be directly processed. The UHF / VHF communication channel is specifically used to send the collected audio signals to the terminal device for subsequent audio playback.
[0108] The microphone mainly consists of a CPU, an audio wireless transmission module, a communication wireless transmission and reception module, and an audio processing module. The CPU is used to set the operating parameters of each module, the microphone is used to collect sound, the audio processing module is used for functions such as gain control of the sound signal, A / D conversion, and volume extraction, the audio wireless transmission module is used to transmit the processed audio signal through a UHF or VHF wireless channel, and the communication wireless transmission and reception module uses the WIFI protocol for bidirectional wireless communication between the CPU in the microphone and the CPU in the receiver.
[0109] Step S20: Generate initial audio signaling based on the volume level and the audio duration, and send the initial audio signaling to the terminal device so that the terminal device can respond with an audio transmission command.
[0110] It is worth noting that the data format of the initial audio signaling is the same as that of the WiFi communication protocol to facilitate subsequent data transmission, and the steps for sending the initial audio signaling to the terminal device include:
[0111] The wireless audio transmission function is activated according to the audio transmission command to connect the target audio channel between the audio acquisition device and the terminal device;
[0112] The audio signal is modulated;
[0113] The modulated audio signal is transmitted to the terminal device through the target audio channel.
[0114] Step S30: The audio signal is sent to the terminal device according to the audio transmission instruction, so that the terminal device forwards the audio signal to an external playback device for audio playback.
[0115] In the implementation, the audio signal inside the microphone is collected by the microphone head and sent to the audio processing module. The CPU reads the currently collected volume value from the audio processing module and sends it to the CPU in the receiver via Wi-Fi. Multiple microphones perform the above process simultaneously, uploading their current volume values to the receiver's CPU. The receiver's CPU compares all received microphone volume values, processes them using a specific algorithm, and selects the microphone to be used for sound acquisition. It then notifies the CPU of that microphone via Wi-Fi to enable the wireless audio transmission function and notifies the CPUs of other microphones to disable the wireless audio transmission function. The selected microphone modulates the audio signal and transmits it from the UHF or VHF channel. The receiver receives the audio signal on the corresponding UHF / VHF channel, demodulates it, processes it through the audio processing module, and then sends it to an external device.
[0116] In this embodiment, upon acquiring an audio signal, the volume level and duration of the audio signal are determined; an initial audio signaling is generated based on the volume level and duration, and the initial audio signaling is sent to the terminal device so that the terminal device can respond with an audio transmission command; the audio signal is sent to the terminal device according to the audio transmission command so that the terminal device can forward the audio signal to an external playback device for audio playback. This embodiment first determines the volume level and duration of the audio signal, and generates an initial audio signaling in the corresponding format according to the WiFi communication protocol, so that the terminal device can determine the microphone to open the communication channel and realize the playback of the audio signal.
[0117] Reference Figure 8 , Figure 8 This is a structural block diagram of the first embodiment of the audio co-channel playback device of the present invention.
[0118] like Figure 8 As shown, the audio co-channel playback device proposed in this embodiment of the invention includes:
[0119] The audio acquisition module 100 is used to determine the volume level and duration of the audio signal when an audio signal is acquired.
[0120] The signaling generation module 200 is used to generate initial audio signaling based on the volume level and the audio duration, and send the initial audio signaling to the terminal device so that the terminal device can respond with an audio transmission command.
[0121] The signal transmission module 300 is used to send the audio signal to the terminal device according to the audio transmission instruction, so that the terminal device forwards the audio signal to an external playback device for audio playback.
[0122] In this embodiment, upon acquiring an audio signal, the volume level and duration of the audio signal are determined; an initial audio signaling is generated based on the volume level and duration, and the initial audio signaling is sent to the terminal device so that the terminal device can respond with an audio transmission command; the audio signal is sent to the terminal device according to the audio transmission command so that the terminal device can forward the audio signal to an external playback device for audio playback. This embodiment first determines the volume level and duration of the audio signal, and generates an initial audio signaling in the corresponding format according to the WiFi communication protocol, so that the terminal device can determine the microphone to open the communication channel and realize the playback of the audio signal.
