[0002] With the rapid development of internet technology, short videos, as an emerging information dissemination medium, have attracted significant traffic. Short videos, characterized by high traffic, high capacity, and rapid dissemination, are poised to become a top choice for advertising media. Wireless microphones are the audio recording devices used in the shooting process of short videos. A wireless microphone consists of a microphone head and an audio receiver. The microphone head captures sound and transmits the captured audio information wirelessly to the audio receiver via Bluetooth. Users can then listen in through the audio receiver or connect it to a terminal device to transmit audio information to that device.

[0003] Traditional wireless microphones typically use two 3.5mm audio jacks for the audio receiver. One jack serves as the Lineout port, through which an audio cable is plugged to transmit the received audio to a connected device. The other jack acts as a monitoring port, allowing users to listen to the audio received by the receiver using wired headphones. However, using two 3.5mm audio jacks on the receiver occupies a significant amount of fabric, resulting in a bulky receiver that is less portable. Summary of the Invention

[0065] Application Overview

[0066] The technical solution of this application embodiment is applicable to the application scenario of audio processing of audio receiving devices. By adopting the technical solution of this application embodiment, the function of switching between linear output and monitoring of the audio socket can be realized according to whether the terminal device connection component in the audio receiving device is in the data transmission working mode. Thus, by setting up an audio socket, both linear output and monitoring functions of the audio socket can be realized, reducing the number of audio sockets, reducing the board area of ​​the audio receiving device, thereby reducing the size of the audio receiving device and improving portability.

[0067] In the currently popular short video field, wireless audio systems are the audio recording devices required for short video shooting. Wireless audio systems are usually equipped with an audio acquisition end and an audio receiving end. For example, wireless microphone products use the audio acquisition end (i.e., the microphone head) to collect the audio information emitted by the user and transmit the audio information wirelessly to the audio receiving end via Bluetooth. The audio receiving end can be used to monitor the audio information or transmit the received audio information to a terminal device connected to the audio receiving end so that the terminal device can perform related operations on the audio information (such as storing or editing the audio information).

[0068] Traditional wireless audio systems use two 3.5mm audio jacks at the audio receiver. One 3.5mm audio jack serves as a monitoring port, allowing wired headphones to be plugged in for listening to the audio received by the receiver. The other 3.5mm audio jack serves as a lineout port, connecting to terminal devices. For example, it can be connected to the Linein port of devices such as cameras, mixers, and sound cards via a 3.5mm TRS to TRS audio cable, or connected to terminal devices with a MICIN interface such as computers and mobile phones via a 3.5mm TRS to TRS audio cable, or first connected to a Type-C to 3.5mm audio adapter cable, and then connected to the Type-C port of terminal devices such as Android phones via a 3.5mm TRS to TRS audio cable.

[0069] It can be seen that in order to enable the audio receiver of a wireless audio system to both monitor audio and output audio linearly to the terminal device, two 3.5mm audio sockets need to be set on the audio receiver. However, two 3.5mm audio sockets will occupy a large area on the PCB board of the audio receiver, so a larger PCB board is required, which will increase the size of the audio receiver and affect its portability.

[0070] Based on this, this application proposes an audio receiving device. This technical solution can switch between the linear output function and the monitoring function of the audio socket by determining whether the terminal device connection component in the audio receiving device is in the data transmission working mode. Thus, it can achieve two functions by setting up an audio socket, thereby solving the problem that the existing audio receiving devices have a large board area, resulting in a large size and low portability.

[0071] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0072] Exemplary device

[0073] This application provides an audio receiving device, see [link to relevant documentation]. Figure 1 As shown, the audio receiving device includes a Bluetooth host controller 101 and an audio jack 102, which are connected. Both the Bluetooth host controller 101 and the audio jack 102 can be mounted on the PCB board of the audio receiving device, and their connection is achieved through the wiring on the PCB board. The audio receiving device also includes a terminal device connection component 103, through which the audio receiving device can connect to a terminal device, enabling data transmission between the audio receiving device and the terminal device.

[0074] In this embodiment, the Bluetooth master controller 101 in the audio receiving device is wirelessly connected to the audio transmitter in the matching audio acquisition device. After acquiring audio information, the audio acquisition device sends the corresponding audio signal to the Bluetooth master controller 101 using the audio transmitter. This audio signal is a digital audio signal. The state of the terminal device connection component 103 in the audio receiving device includes a data transmission working mode and a static mode. The Bluetooth master controller 101 can determine whether the terminal device connection component 103 is in the data transmission working mode based on the connection signal corresponding to the terminal device connection component 103. For example, if the terminal device connection component 103 is a terminal device adapter, then the Bluetooth master controller 101 determines whether the terminal device adapter is inserted into the audio receiving device. If the terminal device adapter is inserted, it means that audio signals need to be transmitted to the terminal device using the terminal device adapter. At this time, it is determined that the terminal device connection component 103 is in the data transmission working mode. If the terminal device connection component 103 is a device socket, the Bluetooth master controller 101 determines whether the device socket is connected to the terminal device through a matching cable. If the device socket is connected to the terminal device, it means that audio signals need to be transmitted to the terminal device using the device socket. At this time, it is determined that the terminal device connection component 103 is in the data transmission working mode.

[0075] When the terminal device connection component 103 is in data transmission mode, the Bluetooth master controller 101 can directly transmit the received audio signal to the terminal device using the terminal device connection component 103. At this time, audio monitoring can be achieved using the audio dock 102. Therefore, the monitoring channel b between the Bluetooth master controller 101 and the audio dock 102 needs to be established. Since the audio dock 102 receives analog signals, while the Bluetooth master controller 101 receives digital audio signals, the Bluetooth master controller 101 needs to use its integrated audio ADC module to convert the digital audio signal into an analog audio signal, and then transmit this analog audio signal to the monitoring channel b. The monitoring channel b can convert the audio signal into an audio signal suitable for monitoring, and then transmit this audio signal to the audio dock 102. At this time, a matching monitoring device can be inserted into the audio dock 102 to achieve audio monitoring. For example, when the terminal device connection component 103 is in data transmission mode, a wired headphone with a plug compatible with the audio dock 102 can be inserted into the audio dock 102 to achieve audio monitoring. In this embodiment, the monitoring channel b converts the audio signal into an audio signal suitable for monitoring. This conversion can be performed using a corresponding signal conversion component or a controller that can perform the conversion. This embodiment does not impose any specific limitations, as long as the audio signal in the monitoring channel b can be converted into an audio signal suitable for monitoring.

[0076] When the terminal device connection component 103 is in static mode, i.e., not in data transmission mode, the Bluetooth master controller 101 needs to use the audio dock 102 to transmit audio signals with the terminal device. Therefore, the linear output channel a between the Bluetooth master controller 101 and the audio dock 102 needs to be activated. The Bluetooth master controller 101 uses the linear output channel a to transmit the audio signal (i.e., analog audio signal) to the audio dock 102. At this time, a cable matching the audio dock 102 can be used to connect the audio dock 102 and the terminal device. The audio dock 102 transmits the received analog audio signal from the terminal device connection component 103 to the terminal device through the cable. For example, if the audio connector 102 is a 3.5mm audio connector, when not in data transmission mode, it can be connected to the Linein interface of terminal devices such as cameras, mixers, and sound cards using a 3.5mm TRS to TRS audio cable. It can also be connected to terminal devices with MICIN interfaces such as computers and mobile phones using a 3.5mm TRS to TRS audio cable. Alternatively, it can be connected to a Type-C to 3.5mm TRS audio adapter cable first, and then connected to the Type-C port of terminal devices such as Android phones.

[0077] In this embodiment, the linear output channel a between the Bluetooth master controller 101 and the audio dock 102, and the monitoring channel b between the Bluetooth master controller 101 and the audio dock 102, can be switched between the two channels by setting a switch. For example, a first switch is set in the linear output channel a, and a second switch is set in the monitoring channel b. When it is necessary to conduct the linear output channel a, the Bluetooth master controller 101 controls the first switch to close and the second switch to open, so as to conduct the linear output channel a. When it is necessary to conduct the monitoring channel b, the Bluetooth master controller 101 controls the second switch to close and the first switch to open, so as to conduct the monitoring channel b. This embodiment can also utilize the connection between different pins of the Bluetooth master controller 101 and the audio jack 102 to control the output of audio signals from different pins, thereby enabling the conduction of different channels. For example, the connection between the first output pin of the Bluetooth master controller 101 and the audio jack 102 is a linear output channel a, and the connection between the second output pin of the Bluetooth master controller 101 and the audio jack 102 is a monitoring channel b. When linear output channel a needs to be activated, the Bluetooth master controller 101 controls the first output pin to output an audio signal, thus enabling linear output channel a. When monitoring channel b needs to be activated, the Bluetooth master controller 101 controls the second output pin to output an audio signal, thus enabling monitoring channel b. This embodiment does not specifically limit the specific method of switching between linear output channel a and monitoring channel b, as long as it enables monitoring channel b when the terminal device connection component 103 is in data transmission mode and linear output channel a when the terminal device connection component 103 is not in data transmission mode.

[0078] The audio receiving device in this embodiment switches between linear output and monitoring functions of the audio dock 102 depending on whether the terminal device connection component 103 is in data transmission mode. This allows the audio dock 102 to perform both linear output and monitoring functions by setting up one audio dock 102, reducing the number of audio docks 102 required, reducing the board area of ​​the audio receiving device, and thus reducing the size of the audio receiving device and improving its portability.

[0079] As an optional implementation method, such as Figure 2As shown in another embodiment of this application, a headphone amplifier assembly 104 and a headphone amplifier are provided in the monitoring channel b of the audio receiving device. The headphone amplifier assembly 104 can amplify the received audio signal so that the audio signal transmitted to the audio dock 102 is suitable for the monitoring device connected to the audio dock 102. Specifically, when the Bluetooth master controller 101 determines that the terminal device connection assembly 103 is in the data transmission working mode, the Bluetooth master controller 101 controls the monitoring channel b between the Bluetooth master controller 101 and the audio dock 102 to be turned on. The Bluetooth master controller 101 transmits the audio signal (i.e., analog audio signal) through the monitoring channel b to the headphone amplifier assembly 104 provided in the monitoring channel b. The headphone amplifier assembly 104 amplifies the received audio signal and then outputs the amplified audio signal. The amplified audio signal continues to be transmitted to the audio dock 102 through the monitoring channel b so that the monitoring device connected to the audio dock 102 can receive the amplified audio signal and realize audio monitoring.

[0080] As an optional implementation method, such as Figure 2 As shown in another embodiment of this application, the audio receiving device further includes an audio analog switch 105. The Bluetooth master controller 101 is connected to the audio dock 102 via the audio analog switch 105. The audio analog switch 105 is used to, based on the control of the Bluetooth master controller 101, either activate the linear transmission channel a between the Bluetooth master controller 101 and the audio dock 102, or activate the monitoring channel b between the Bluetooth master controller 101 and the audio dock 102. Specifically, when the Bluetooth master controller 101 determines that the terminal device connection component 103 is in data transmission mode, the Bluetooth master controller 101 controls the audio analog switch 105 to activate the monitoring channel b between the Bluetooth master controller 101 and the audio dock 102; when the Bluetooth master controller 101 determines that the terminal device connection component 103 is not in data transmission mode, the Bluetooth master controller 101 controls the audio analog switch 105 to activate the linear transmission channel a between the Bluetooth master controller 101 and the audio dock 102.

[0081] For example, the audio analog switch 105 in this embodiment can be a double-pole double-throw switch, or a chip capable of simulating a double-pole double-throw switch function. Figure 3As shown, the audio signals received by the Bluetooth master controller 101 include a left channel audio signal L0 and a right channel audio signal R0. Therefore, the ADC pins of the Bluetooth master controller 101 include left channel pins and right channel pins. The left channel pins of the Bluetooth master controller 101 are connected to the NC1 pin of the audio analog switch 105 and the headphone amplifier assembly 104, respectively. The right channel pins of the Bluetooth master controller 101 are connected to the NC2 pin of the audio analog switch 105 and the headphone amplifier assembly 104. The audio dock 102 and the headphone amplifier assembly 104 also include left channel pins and right channel pins. The left channel pin of the audio dock 102 is connected to the COM1 pin of the audio analog switch 105, and the right channel pin of the audio dock 102 is connected to the COM2 pin of the audio analog switch 105. The left channel pin of the headphone amplifier assembly 104 is connected to the NO1 pin of the audio analog switch 105, and the right channel pin of the headphone amplifier assembly is connected to the NO2 pin of the audio analog switch 105. The GPIO pins of the Bluetooth host controller 101 are connected to pins IN1 and IN2 of the audio analog switch 105, respectively.

[0082] When the Bluetooth master controller 101 determines that the terminal device connection component 103 is in the data transmission working mode, the Bluetooth master controller 101 outputs a first signal through the GPIO pin. This first signal is transmitted to the IN1 and IN2 pins of the audio analog switch 105, so that the IN1 pin controls the conduction between the COM1 and NO1 pins of the audio analog switch based on the first signal, and the IN2 pin controls the conduction between the COM2 and NO2 pins of the audio analog switch based on the first signal. This enables the conduction between the left channel pin of the audio dock 102 and the left channel pin of the headphone amplifier component 104, as well as the conduction between the right channel pin of the audio dock 102 and the right channel pin of the headphone amplifier component 104. At this time, the left channel audio signal L0 output from the left channel pin of the Bluetooth master controller 101 is amplified by the headphone amplifier assembly 104. The amplified left channel audio signal L1 is output from the left channel pin of the headphone amplifier assembly 104. The amplified left channel audio signal L1 is transmitted to the left channel pin of the audio dock 102 through the path formed by pin NO1 and pin COM1 of the audio analog switch 105, and serves as the left channel audio signal L received by the audio dock 102. The right channel audio signal R0 output from the right channel pin of the Bluetooth master controller 101 is amplified by the headphone amplifier assembly 104. The amplified right channel audio signal R1 is output from the right channel pin of the headphone amplifier assembly 104. The amplified right channel audio signal R1 is transmitted to the right channel pin of the audio dock 102 through the path formed by pin NO2 and pin COM2 of the audio analog switch 105, and serves as the right channel audio signal R received by the audio dock 102.

[0083] When the Bluetooth master controller 101 determines that the terminal device connection component 103 is not in data transmission mode, the Bluetooth master controller 101 outputs a second signal through the GPIO pin. This second signal is transmitted to pins IN1 and IN2 of the audio analog switch 105, so that pin IN1 controls the conduction between pins COM1 and NC1 of the audio analog switch based on the second signal, and pin IN2 controls the conduction between pins COM2 and NC2 of the audio analog switch based on the second signal. This enables the conduction between the left channel pin of the audio dock 102 and the left channel pin of the Bluetooth master controller 101, as well as the conduction between the right channel pin of the audio dock 102 and the right channel of the Bluetooth master controller 101. At this time, the left channel audio signal L0 output by the left channel pin of the Bluetooth master controller 101 is transmitted to the left channel pin of the audio dock 102 through the path formed by pins NC1 and COM1 of the audio analog switch 105, serving as the left channel audio signal L received by the audio dock 102. The right channel audio signal R0 output from the right channel pin of the Bluetooth host controller 101 is transmitted to the right channel pin of the audio dock 102 through the path formed by the pins NC2 and COM2 of the audio analog switch 105, and is received by the audio dock 102 as the right channel audio signal R.

[0084] As an optional implementation method, such as Figure 4 As shown in another embodiment of this application, a terminal device connection component 103 in an audio receiving device includes a connection adapter 1031 and a terminal device adapter 1032. The first end of the connection adapter 1031 is connected to the Bluetooth host controller 101. The terminal device adapter 1032 is an independently configured module. When it is necessary to use the terminal device adapter 1032 to establish a connection between the Bluetooth host controller 101 and a terminal device, the terminal device adapter 1032 can be inserted into the audio receiving device to connect the second end of the connection adapter 1031. This allows the Bluetooth host controller 101 to connect to the terminal device adapter 1032 via the connection adapter 1031, enabling signal transmission between the Bluetooth host controller 101 and the terminal device adapter 1032. The terminal device adapter 1032 connects to a terminal device that is compatible with it, thereby transmitting the audio signal sent by the Bluetooth host controller 101 to the terminal device.

[0085] As an optional implementation, if the terminal device connection component includes a connection adapter 1031 and a terminal device adapter 1032, and the terminal device adapter 1032 is provided with a resistor, when the terminal device adapter 1032 is inserted into the audio receiving device and connected to the second end of the connection adapter 1031, the connection adapter 1031 sends the voltage signal emitted by the Bluetooth master controller 101 to the terminal device adapter. The resistor provided in the terminal device adapter 1032 will divide the voltage signal and feed back the divided voltage signal to the Bluetooth master controller 101. That is, the connection adapter 1031 transmits the divided voltage signal fed back by the terminal device adapter 1032 to the Bluetooth master controller 101. When the terminal device adapter 1032 is not inserted into the audio receiving device, since there is no resistor in the terminal device adapter 1032 to divide the voltage signal emitted by the Bluetooth master controller 101, the voltage division signal fed back to the Bluetooth master controller 101 by the connection adapter 1031 will necessarily be different from the voltage division signal fed back to the Bluetooth master controller 101 when the terminal device adapter 1032 is inserted into the audio receiving device and connected to the second end of the connection adapter 1031.

[0086] The Bluetooth master controller 101 can receive the voltage divider signal sent by the connection adapter 1031 and determine whether the terminal device adapter 1032 is plugged into the audio receiving device and connected to the second end of the connection adapter 1031 based on the voltage divider signal. When the difference between the voltage value corresponding to the voltage divider signal received by the Bluetooth master controller 101 and the voltage value corresponding to the voltage signal pre-sent by the Bluetooth master controller 101 is within a preset voltage difference range, it indicates that the voltage signal pre-sent by the Bluetooth master controller 101 has not been divided, and therefore it is determined that the terminal device adapter 1032 is not connected to the connection adapter 1031. When the difference between the voltage value corresponding to the voltage divider signal received by the Bluetooth master controller 101 and the voltage value corresponding to the voltage signal pre-sent by the Bluetooth master controller 101 exceeds the preset voltage difference range, it indicates that the voltage signal pre-sent by the Bluetooth master controller 101 has been divided, and therefore it is determined that the terminal device adapter 1032 is connected to the connection adapter 1031. If the terminal device adapter 1032 is connected to the connection adapter 1031, the Bluetooth master controller 101 determines that the terminal device connection component 103 is in the data transmission working mode; if the terminal device adapter 1032 is not connected to the connection adapter 1031, the Bluetooth master controller 101 determines that the terminal device connection component 103 is not in the data transmission working mode.

[0087] This embodiment, by setting up a terminal device adapter 1032, allows the terminal device adapter to be directly inserted into the terminal device's jack when connected to a terminal device, eliminating the need for cable connections and improving the convenience of the audio receiving device.

[0088] As an optional implementation method, such as Figure 4 and Figure 5 As shown in another embodiment of this application, the terminal device adapter 1032 includes either a first terminal device adapter 10321 or a second terminal device adapter 10322. Since only one adapter 1031 is provided in this embodiment, the first terminal device adapter 10321 and the second terminal device adapter 10322 cannot be simultaneously inserted into the audio receiving device; only one can be selected and inserted into the audio receiving device to connect to the adapter 1031. The first terminal device adapter 10321 is provided with a first resistor R1, and the second terminal device adapter 10322 is provided with a second resistor R2, wherein the resistance values ​​of the first resistor R1 and the second resistor R2 are different. Because the two resistors have different resistance values, their voltage division capabilities are also different. Therefore, the voltage value corresponding to the voltage division signal fed back by the first terminal device adapter 10321 after receiving the voltage signal sent by the connection adapter 1031 will inevitably be different from the voltage value corresponding to the voltage division signal fed back by the second terminal device adapter 10322 after receiving the voltage signal sent by the connection adapter 1031. In this embodiment, a first pressure range and a second pressure range are preset. The voltage corresponding to the voltage signal sent by the Bluetooth master controller 101 is the original voltage. The first pressure range is the range of voltage values ​​after the original voltage is divided by the first resistor R1, and the second pressure range is the range of voltage values ​​after the original voltage is divided by the second resistor R2. If the pressure value corresponding to the voltage divider signal sent by the connection adapter 1031 received by the Bluetooth master controller 101 is within the first pressure range, it is determined that the first terminal device adapter 10321 is connected to the connection adapter 1031; if the pressure value corresponding to the voltage divider signal sent by the connection adapter 1031 received by the Bluetooth master controller 101 is within the second pressure range, it is determined that the second terminal device adapter 10322 is connected to the connection adapter 1031; if the pressure value corresponding to the voltage divider signal sent by the connection adapter 1031 received by the Bluetooth master controller 101 is the original voltage, it is determined that the connection adapter 1031 is not connected to the terminal device adapter. In this embodiment, different types of terminal device adapters may require different parameter information in the audio signal. Therefore, by identifying the terminal device adapter connected to the connection adapter 1031, the Bluetooth master controller 101 can configure the parameter information in the transmitted audio signal according to the type of the connected terminal device adapter, such as volume parameters, thereby improving the matching degree between the audio signal transmitted by the Bluetooth master controller 101 and the terminal device adapter.

[0089] Specifically, pins DEC1_CTRL of the first terminal device adapter 10321 and the second terminal device adapter 10322 can both be connected to pin DEC1_CTRL of the connection adapter 1031. The GPIO pin of the Bluetooth master controller 101 is connected to the connection adapter 1031. The Bluetooth master controller 101 is connected to the power supply V via resistor R3.

[0090] For example, the resistance of the first resistor R1 is set to 100K, the resistance of the second resistor R2 is set to 10K, the resistance of the third resistor R3 is set to 100K, and the voltage of the power supply V is set to 3.1V. When the pin DEC1_CTRL of the first terminal device adapter 10321 is connected to the pin DEC1_CTRL of the connection adapter 1031, the voltage received by the GPIO pin of the Bluetooth master controller 101 is 1.55V, and the first pressure range is set to ±10% of 1.55V. When the pin DEC1_CTRL of the second terminal device adapter 10322 is connected to the pin DEC1_CTRL of the connection adapter 1031, the voltage received by the GPIO pin of the Bluetooth master controller 101 is 0.28V, and the second pressure range is set to ±10% of 0.28V. When adapter 1031 is used as a terminal device adapter, the voltage received by the GPIO pin of Bluetooth master controller 101 is 3.1V, and the original voltage is set to 3.1V. At this time, the type of terminal device adapter connected to adapter 1031 can be determined based on the pressure value corresponding to the voltage divider signal received by Bluetooth master controller 101.

[0091] As an optional implementation, another embodiment of this application discloses that the first terminal device adapter 10321 takes a digital audio signal as input, and the second terminal device adapter 10322 takes an analog audio signal as input. The Bluetooth master controller 101 receives the digital audio signal sent by the audio transmitter. If the first terminal device adapter 10321 is inserted into the audio receiving device and connected to the connection adapter 1031, the Bluetooth master controller 101 uses its integrated USB module to directly transmit the digital audio signal to the first terminal device adapter 10321 through the connection adapter 1031. If the second terminal device adapter 10322 is inserted into the audio receiving device and connected to the connection adapter 1031, the Bluetooth master controller 101 uses its integrated ADC module to convert the digital audio signal into an analog audio signal and transmits the analog audio signal to the second terminal device adapter 10322 through the connection adapter 1031. This embodiment can support the transmission of both digital and analog audio signals, improving the compatibility of audio receiving devices. Furthermore, by using digital audio formats to transmit audio signals, it can increase the anti-interference capability of audio signals during transmission.

[0092] As an optional implementation, another embodiment of this application discloses that the terminal device connection component 103 includes a device socket 1033. This device socket 1033 is connected to the Bluetooth host 101 and can connect to a terminal device via a transmission cable adapted to the device socket 1033, outputting audio signals sent by the Bluetooth host 101 to the terminal device. The device socket 1033 can be a socket that accepts digital audio signals as input or a socket that accepts analog audio signals as input.

[0093] The Bluetooth host controller 101 can obtain the USB enumeration signal corresponding to the device socket 1033 via the USB protocol. Based on this USB enumeration signal, it determines whether the device socket 1033 has been successfully enumerated via USB. If the USB enumeration is successful, it means that the device socket 1033 is connected to the terminal device; if the USB enumeration is unsuccessful, it means that the device socket 1033 is not connected to the terminal device. If the device socket 1033 is connected to the terminal device, the Bluetooth host controller 101 determines that the terminal device connection component 103 is in the data transmission working mode; if the device socket 1033 is not connected to the terminal device, the Bluetooth host controller 101 determines that the terminal device connection component 103 is not in the data transmission working mode.

[0094] In this embodiment, the device socket 1033 can also be connected to the power supply component in the audio receiving device. The power supply component in the audio receiving device can be charged through the connection of the device socket 1033 to an external power source.

[0095] As an optional implementation method, such as Figure 6As shown in another embodiment of this application, the audio receiving device further includes a USB analog switch 106. The terminal device connection component 103 includes a connection adapter 1031, a first terminal device adapter 10321, and a device socket 1033. Both the first terminal device adapter 10321 and the device socket 1033 accept digital audio signals as input. The first terminal device adapter 10321 is connected to the USB analog switch 106 via the connection adapter 1031. The USB analog switch 106 is connected to both the Bluetooth host controller 101 and the device socket 1033. The first terminal device adapter 10321 is inserted into the audio receiving device and connected to the connection adapter 1031. When the first terminal device adapter 10321 is connected to the terminal device, it sends a voltage signal carrying a preset voltage to the USB analog switch 106. This voltage signal causes the USB analog switch 106 to open the path between the first terminal device adapter 10321 and the Bluetooth host controller 101. When the first terminal device adapter 10321 is not connected to the terminal device, or when the connection adapter 1031 is not connected to the terminal device adapter, the voltage signal received by the USB analog switch 106 indicates no voltage. In this case, the USB analog switch 106 opens the path between the device socket 1033 and the Bluetooth host controller 101. The preset voltage is the voltage value corresponding to the voltage signal received by the USB analog switch 106 when the first terminal device adapter 10321 is connected to the terminal device.

[0096] For example, the USB analog switch 106 in this embodiment can be a double-pole double-throw switch, or a chip capable of simulating a double-pole double-throw switch function. Figure 7 As shown, the Bluetooth host controller 101 is connected to pins COM1 and COM2 of the USB analog switch 106. The digital audio signal output by the Bluetooth host controller 101 includes a DP signal and a DM signal. The DP signal is input to pin COM1 of the USB analog switch 106, and the DM signal is input to pin COM2 of the USB analog switch 106. Pin DP of the device socket 1033 is connected to pin NC1 of the USB analog switch 106, and pin DM of the device socket 1033 is connected to pin NC2 of the USB analog switch 106. Pin DP of the first terminal device adapter 10321 is connected to pin NO1 of the USB analog switch 106, and pin DM of the first terminal device adapter 10321 is connected to pin NO2 of the USB analog switch 106. Specifically, pin DP of the first terminal device adapter 10321 is connected to pin NO1 of the USB analog switch 106 via adapter 1031, and pin DM of the first terminal device adapter 10321 is connected to pin NO2 of the USB analog switch 106 via adapter 1031. Figure 7 (Not shown). The VBUS pin of the first terminal device adapter 10321 is grounded through the fourth resistor R4 and the fifth resistor R5. The S pin of the USB analog switch 106 is connected to the fourth resistor R4 and the fifth resistor R5, respectively. The resistance of the fourth resistor R4 is 68KΩ, and the resistance of the fifth resistor R5 is 100KΩ. A 5.1KΩ resistor is connected to GND on the CC pin of the first terminal device adapter 10321. Figure 7 Not shown in the image.

[0097] like Figure 7 As shown, when the first terminal device adapter 10321 is connected to the terminal device, the voltage value of the VBUS pin of the first terminal device adapter 10321 is 5V. After being divided by the voltage divider circuit formed by the fourth resistor R4 and the fifth resistor R5, a voltage of 3.1V is obtained. This voltage signal is transmitted to the pin S of the USB analog switch 106 to set the pin S of the USB analog switch 106 to 1. The logic gate LOGIC controls the pin COM1 of the USB analog switch 106 to connect to the pin NO1, and the pin COM2 of the USB analog switch 106 to connect to the pin NO2, thereby realizing the conduction of the path between the first terminal device adapter 10321 and the Bluetooth host controller 101. When the first terminal device adapter 10321 is not connected to a terminal device, its pin VBUS has no voltage. Therefore, the voltage signal transmitted to pin S of the USB analog switch 106 also indicates no voltage. At this time, pin S of the USB analog switch 106 is set to 0. The logic gate LOGIC controls pin COM1 of the USB analog switch 106 to connect to pin NC1, and pin COM2 to connect to pin NC2, thus establishing a conductive path between device socket 1033 and Bluetooth host controller 101. When the first terminal device adapter 10321 is connected to a terminal device, and device socket 1033 is also connected to the terminal device via a transmission cable, only the path between the first terminal device adapter 10321 and Bluetooth host controller 101 is established, while the path between device socket 1033 and Bluetooth host controller 101 is disconnected. This ensures that the path priority of the first terminal device adapter 10321 is higher than that of device socket 1033.

[0098] In this embodiment, the USB analog switch 106 can automatically trigger a switching action based on whether the first terminal device adapter 10321 is connected to the terminal device, thus realizing that the path priority of the first terminal device adapter 10321 is greater than that of the device socket 1033. This allows the device socket to be used when the terminal device adapter can be used, thereby reducing the need to connect the terminal device with a cable and improving the convenience of the audio receiving device.

[0099] Furthermore, in this embodiment, the connector 1031 preferably uses a Pogopin connector, the first terminal device connector 10321 preferably uses a Type-C connector, the second terminal device connector 10322 preferably uses a Lightning connector, and the device socket 1033 includes a Type-C socket, a USB socket, etc., preferably using a Type-C socket. The Type-C connector takes a digital audio signal as input and directly transmits the digital audio signal to the connected terminal device. The Lightning connector takes an analog audio signal as input, converts the analog audio signal to a digital audio signal, and then transmits the digital audio signal to the connected terminal device. The Pogopin connector includes eight contacts: MIC, AGND, GND, DEC1_CTRL, VBUS, CC, DP, and DM. The first end of the Type-C adapter is the Type-C end, used for insertion into the Type-C jack of the terminal device. The second end of the Type-C adapter has eight contacts: NC, NC, GND, DEC1_CTRL, VBUS, CC, DP, and DM. The same contacts on the second end of the Type-C adapter are interconnected with those on the Pogopin adapter. The first end of the Lightning adapter is the Lightning end, used for insertion into the Lightning jack of the terminal device. The second end of the Lightning adapter has four contacts: AGND, MIC, GND, and DEC1_CTRL. The same contacts on the second end of the Lightning adapter are interconnected with those on the Pogopin adapter. The connections of the contacts in these adapters have been shown in the circuit diagram above and will not be described in detail in this embodiment.
