Detailed Description

Summary of the application

The technical scheme of the embodiment of the application is suitable for the application scene of audio processing of the audio receiving equipment, and can realize the function switching between the linear output and monitoring of the audio seat according to whether the terminal equipment connecting assembly in the audio receiving equipment is in a data transmission working mode or not, so that the two functions of the linear output and monitoring of the audio seat can be realized by arranging one audio seat, the number of the arranged audio seats is reduced, the layout area of the audio receiving equipment is reduced, the volume of the audio receiving equipment is reduced, and the carrying convenience is improved.

In the currently popular short video field, a wireless audio system is a radio device required for capturing short videos, and is generally provided with an audio acquisition end and an audio receiving end, for example, a wireless microphone product, wherein the audio acquisition end (i.e., a microphone head) is utilized to acquire audio information sent by a user, and the audio information is wirelessly transmitted to the audio receiving end through bluetooth, so that monitoring of the audio information or transmission of the received audio information to a terminal device connected to the audio receiving end can be realized through the audio receiving end, and related operations (for example, storage or clipping of the audio information and the like) are performed on the audio information by using the terminal device.

The audio receiving end of the traditional wireless audio system is provided with two 3.5mm audio seats, wherein one 3.5mm audio seat is used as a monitoring port, and a wired earphone is inserted into the monitoring port to realize monitoring of audio information received by the audio receiving end; the other 3.5mm audio seat is used as a linear output (Lineout) port, and is connected with a terminal device, for example, the Linein port of a camera, a sound mixing table, a sound card and other devices is connected with a 3.5mm TRS (TRS) conversion audio line, or the Linein port is connected with a terminal device with a MICIN port of a computer, a mobile phone and the like through a 3.5mm TRS conversion TRRS audio line, or the lineC is firstly connected with a typeC-3.5 mm audio switching line, and then the lineC port is connected with the terminal device of an android mobile phone and the like.

Therefore, in order to realize the function that the audio receiving end of the wireless audio system can perform audio monitoring and can perform audio linear output to the terminal equipment, two 3.5mm audio seats are required to be arranged at the audio receiving end, but the two 3.5mm audio seats occupy a larger cloth plate area on a PCB board of the audio receiving end, so that the PCB board with a larger area is required to be adopted, the volume of the audio receiving end is increased, and the carrying convenience of the audio receiving end is affected.

Based on the above, the application provides the audio receiving device, and the technical scheme can switch the linear output function and the monitoring function of the audio seat by judging whether the terminal device connecting component in the audio receiving device is in the data transmission working mode, so that the two functions can be realized by setting one audio seat, and the problems of large cloth area of the audio receiving device, large volume of the audio receiving device and low carrying convenience in the prior art are solved.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Exemplary apparatus

An embodiment of the present application proposes an audio receiving apparatus, as shown in fig. 1, including: the Bluetooth master 101 and the audio pad 102, wherein the Bluetooth master 101 and the audio pad 102 are connected. The bluetooth master controller 101 and the audio seat 102 can be arranged on a PCB of the audio receiving device, and the connection relationship between the bluetooth master controller and the audio seat is realized by utilizing the circuits laid on the PCB. The audio receiving device is also provided with a terminal device connecting component 103, and the audio receiving device can be connected with the terminal device through the terminal device connecting component 103, so that data transmission between the audio receiving device and the terminal device is realized.

The bluetooth master controller 101 in the audio receiving device of the embodiment is connected with the audio transmitter in the audio acquisition device matched with the audio receiving device through a wireless signal. After the audio collection device collects the audio information, an audio transmitter is utilized to send an audio signal corresponding to the audio information to the Bluetooth master controller 101, wherein the audio signal is a digital audio signal. The state of the terminal device connection assembly 103 in the audio receiving device includes a data transmission working mode and a static mode, and the bluetooth master 101 can determine whether the terminal device connection assembly 103 is in the data transmission working mode according to the connection signal corresponding to the terminal device connection assembly 103. For example, if the terminal device connection assembly 103 is a terminal device adapter, the bluetooth master controller 101 determines whether the terminal device adapter is inserted into the audio receiving device, and if the terminal device adapter is inserted, which indicates that the terminal device adapter needs to be used for transmitting an audio signal to the terminal device, then the terminal device connection assembly 103 is determined to be in a data transmission working mode; if the terminal device connection assembly 103 is a device socket, the bluetooth master controller 101 determines whether the device socket is connected to the terminal device through a matched cable, and when the device socket is connected to the terminal device, it indicates that the device socket needs to be used for transmitting an audio signal to the terminal device, and then it is determined that the terminal device connection assembly 103 is in a data transmission working mode.

When the terminal device connection assembly 103 is in the data transmission working mode, the bluetooth master 101 can directly transmit the received audio signal to the terminal device by using the terminal device connection assembly 103, and the audio monitoring function can be realized by using the audio seat 102 at this time, so that the monitoring channel b between the bluetooth master 101 and the audio seat 102 needs to be conducted at this time. Because the receivable signal of the audio base 102 is an analog signal, and the audio signal received by the bluetooth master controller 101 is a digital audio signal, the bluetooth master controller 101 needs to convert the digital audio signal into an analog audio signal by using an audio ADC module integrated inside the bluetooth master controller, and then transmit the analog audio signal to the listening channel b, where the listening channel b can convert the audio signal into an audio signal suitable for listening, and then transmit the audio signal to the audio base 102. At this time, a matched listening device may be inserted into the audio pad 102, thereby implementing audio listening. For example, when the terminal device connection component 103 is in the data transmission operation mode, a wired earphone with a plug matched with the audio seat 102 may be inserted into the audio seat 102, so as to realize audio monitoring. The audio signal is converted into an audio signal suitable for monitoring by the monitoring channel b, the signal conversion can be performed by using a corresponding signal conversion component, the signal conversion can also be performed by using a controller capable of realizing a corresponding conversion function, and the like, and the embodiment is not particularly limited as long as the audio signal in the monitoring channel b can be converted into the audio signal suitable for monitoring.

When the terminal device connection assembly 103 is in the static mode, i.e. not in the data transmission operation mode, the bluetooth master 101 needs to use the audio socket 102 to realize audio signal transmission with the terminal device, so that at this time, a linear output channel a between the bluetooth master 101 and the audio socket 102 needs to be conducted, and the bluetooth master 101 uses the linear output channel a to transmit the audio signal (i.e. the analog audio signal) to the audio socket 102. At this time, the connection between the audio pad 102 and the terminal device may be implemented by using a cable matched with the audio pad 102, and the audio pad 102 transmits the received analog audio terminal device connection component 103 frequency signal to the terminal device through the cable. For example, if the audio base 102 is a 3.5mm audio base, when not in the data transmission working mode, the 3.5mm TRS transfer TRS audio line may be used to connect to a Linein interface of a terminal device such as a camera, a mixing station, and a sound card, or the 3.5mm TRS transfer TRRS audio line may be used to connect to a terminal device such as a computer and a mobile phone with a MICIN interface, or the 3.5mm TRS transfer TRRS audio line may be used to connect to a typeC-to-3.5 mm TRRS audio patch line first, and then connect to a typeC port of a terminal device such as an android mobile phone.

In this embodiment, the linear output channel a between the bluetooth master 101 and the audio seat 102 and the listening channel b between the bluetooth master 101 and the audio seat 102 may be switched 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 listening channel b, when the linear output channel a needs to be turned on, the bluetooth master 101 controls the first switch to be turned on, the second switch to be turned off, so as to realize the conduction of the linear output channel a, and when the listening channel b needs to be turned on, the bluetooth master 101 controls the second switch to be turned on, and the first switch is turned off, so as to realize the conduction of the listening channel b. In this embodiment, the connection between different pins of the bluetooth master 101 and the audio seat 102 may be further utilized, and audio signals are output by controlling the different pins, so as to realize conduction of different channels, for example, the connection between the first output pin of the bluetooth master 101 and the audio seat 102 is a linear output channel a, the connection between the second output pin of the bluetooth master 101 and the audio seat 102 is a listening channel b, when the linear output channel a needs to be conducted, the bluetooth master 101 controls the first output pin to output audio signals, so as to realize conduction of the linear output channel a, and when the listening channel b needs to be conducted, the bluetooth master 101 controls the second output pin to output audio signals, so as to realize conduction of the listening channel b. The specific manner of switching the linear output channel a and the listening channel b is not particularly limited in this embodiment, as long as the listening channel b is turned on when the terminal device connection assembly 103 is in the data transmission operation mode, and the linear output channel a is turned on when the terminal device connection assembly 103 is not in the data transmission operation mode.

According to the audio receiving device of the embodiment, according to whether the terminal device connection assembly 103 is in the data transmission working mode or not, the function switching between the linear output and monitoring of the audio seat 102 is realized, so that the two functions of the linear output and monitoring of the audio seat 102 can be realized by arranging one audio seat 102, the number of the arranged audio seats 102 is reduced, the layout area of the audio receiving device is reduced, the volume of the audio receiving device is reduced, and the carrying convenience is improved.

As an alternative implementation manner, as shown in fig. 2, in another embodiment of the present application, an ear amplifier component 104 and an ear amplifier are disposed in a listening channel b in an audio receiving apparatus. The earbud assembly 104 may amplify the received audio signal to enable the audio signal transmitted to the audio pad 102 to be adapted to a listening device coupled to the audio pad 102. Specifically, 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 controls the monitoring channel b between the bluetooth master controller 101 and the audio seat 102 to be turned on, the bluetooth master controller 101 transmits an audio signal (i.e. an analog audio signal) through the monitoring channel b, the audio signal is transmitted to the ear amplifier component 104 arranged in the monitoring channel b, the ear amplifier component 104 amplifies the received audio signal, and then outputs the amplified audio signal, and the amplified audio signal is continuously transmitted to the audio seat 102 through the monitoring channel b, so that the monitoring device connected with the audio seat 102 receives the amplified audio signal to realize audio monitoring.

As an alternative implementation, as shown in fig. 2, in another embodiment of the present application, an audio receiving apparatus is disclosed that further includes an audio analog switch 105. The bluetooth master 101 is connected to the audio pad 102 via an audio analog switch 105. The audio analog switch 105 is used for switching on a linear transmission channel a between the bluetooth master 101 and the audio pad 102 or switching on a listening channel b between the bluetooth master 101 and the audio pad 102 based on the control of the bluetooth master 101. 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 audio analog switch 105 to conduct the monitoring channel b between the bluetooth master controller 101 and the audio seat 102; when the bluetooth master controller 101 determines that the terminal device connection assembly 103 is not in the data transmission operation mode, the bluetooth master controller 101 controls the audio analog switch 105 to conduct the linear transmission channel a between the bluetooth master controller 101 and the audio seat 102.

For example, the audio analog switch 105 in the present embodiment may employ a double pole double throw switch, or a chip that can realize an analog double pole double throw switch function. As shown in fig. 3, the audio signal received by the bluetooth master 101 includes a left channel audio signal L0 and a right channel audio signal R0, so that the pin ADC of the bluetooth master 101 includes a left channel pin and a right channel pin, the left channel pin of the bluetooth master 101 is respectively connected to the pin NC1 of the audio analog switch 105 and the ear amplifier 104, and the right channel pin of the bluetooth master 101 is respectively connected to the pin NC2 of the audio analog switch 105 and the ear amplifier 104. The audio pad 102 and the ear speaker assembly 104 also include a left channel pin and a right channel pin, the left channel pin of the audio pad 102 being coupled to pin COM1 of the audio analog switch 105 and the right channel pin of the audio pad 102 being coupled to pin COM2 of the audio analog switch 105. The left channel pin of the ear amplifier assembly 104 is connected to pin NO1 of the audio analog switch 105 and the right channel pin of the ear amplifier assembly is connected to pin NO2 of the audio analog switch 105. The pin GPIO of the bluetooth master 101 is connected to the pin IN1 and the pin IN2 of the audio analog switch 105, respectively.

When the bluetooth master controller 101 determines that the terminal device connection assembly 103 is IN the data transmission operation mode, the bluetooth master controller 101 outputs a first signal through the pin GPIO, and the first signal is transmitted to the pin IN1 and the pin IN2 of the audio analog switch 105, so that the pin IN1 controls conduction between the pin COM1 and the pin NO1 of the audio analog switch based on the first signal, and the pin IN2 controls conduction between the pin COM2 and the pin NO2 of the audio analog switch based on the first signal, thereby enabling conduction between the left channel pin of the audio seat 102 and the left channel pin of the ear playing assembly 104, and conduction between the right channel pin of the audio seat 102 and the right channel of the ear playing assembly 104. At this time, the left channel audio signal L0 output by the left channel pin of the bluetooth master 101 is amplified by the ear amplifier 104, the amplified left channel audio signal L1 is output by the left channel pin of the ear amplifier 104, and the amplified left channel audio signal L1 is transmitted to the left channel pin of the audio pad 102 through the path formed by the pin NO1 and the pin COM1 of the audio analog switch 105, and is used as the left channel audio signal L received by the audio pad 102. The right channel audio signal R0 output by the right channel pin of the bluetooth master 101 is amplified by the ear amplifier assembly 104, the amplified right channel audio signal R1 is output by the right channel pin of the ear amplifier assembly 104, and the amplified right channel audio signal R1 is transmitted to the right channel pin of the audio seat 102 through a channel formed by the pin NO2 and the pin COM2 of the audio analog switch 105, and is used as the right channel audio signal R received by the audio seat 102.

When the bluetooth master 101 determines that the terminal device connection assembly 103 is not IN the data transmission operation mode, the bluetooth master 101 outputs a second signal through the pin GPIO, and the second signal is transmitted to the pin IN1 and the pin IN2 of the audio analog switch 105, so that the pin IN1 controls conduction between the pin COM1 and the pin NC1 of the audio analog switch based on the second signal, and the pin IN2 controls conduction between the pin COM2 and the pin NC2 of the audio analog switch based on the second signal, thereby enabling conduction between the left channel pin of the audio seat 102 and the left channel pin of the bluetooth master 101, and conduction between the right channel pin of the audio seat 102 and the right channel of the bluetooth master 101. At this time, the left audio signal L0 output from the left channel pin of the bluetooth master 101 is transmitted to the left channel pin of the audio pad 102 as the left audio signal L received by the audio pad 102 through the path formed by the pin NC1 and the pin COM1 of the audio analog switch 105. The right audio signal R0 output from the right pin of the bluetooth master 101 is transmitted to the right pin of the audio pad 102 through the path formed by the pin NC2 and the pin COM2 of the audio analog switch 105, and is used as the right audio signal R received by the audio pad 102.

As an alternative implementation, as shown in fig. 4, in another embodiment of the present application, it is disclosed that the terminal device connection component 103 in the audio receiving device includes: a connection adapter 1031 and a terminal device adapter 1032. Wherein, the first end of the connection adapter 1031 is connected to the bluetooth master 101. The terminal device adaptor 1032 is an independently provided module, when the connection between the bluetooth master 101 and the terminal device needs to be implemented by using the terminal device adaptor 1032, the terminal device adaptor 1032 can be inserted into the audio receiving device, so as to implement connection between the terminal device adaptor 1032 and the second end of the connection adaptor 1031, so that the bluetooth master 101 is connected with the terminal device adaptor 1032 through the connection adaptor 1032, and signal transmission between the bluetooth master 101 and the terminal device adaptor 1032 is implemented. The terminal adapter 1032 connects the terminal device matched with the terminal adapter 1032, thereby realizing the transmission of the audio signal sent by the bluetooth master 101 to the terminal device.

As an alternative implementation manner, if the terminal device connection component includes: the connection adaptor 1031 and the terminal device adaptor 1032 are connected, the resistor is arranged in the terminal device adaptor 1032, when the terminal device adaptor 1032 is inserted into the audio receiving device and is connected with the second end of the connection adaptor 1031, the connection adaptor 1031 sends a voltage signal sent by the Bluetooth master 101 to the terminal device adaptor, the resistor arranged in the terminal device adaptor 1032 divides the voltage signal and feeds the divided signal back to the Bluetooth master 101, namely, the connection adaptor 1031 transmits the divided signal fed back by the terminal device adaptor 1032 to the Bluetooth master 101. When the terminal device adaptor 1032 is not inserted into the audio receiving device, since there is no resistor in the terminal device adaptor 1032 dividing the voltage signal sent from the bluetooth master 101, the divided signal fed back to the bluetooth master 101 by the connection adaptor 1031 is necessarily different from the divided signal fed back to the bluetooth master 101 when the terminal device adaptor 1032 is inserted into the audio receiving device and connected to the second end of the connection adaptor 1031.

The bluetooth master 101 may receive the voltage division signal sent by the connection adapter 1031, and determine, according to the voltage division signal, whether the terminal device adapter 1032 is inserted into the audio receiving device, and connect to the second end of the connection adapter 1031. When the difference between the voltage value corresponding to the voltage division signal received by the bluetooth master controller 101 and the voltage value corresponding to the voltage signal sent by the bluetooth master controller 101 in advance is within the preset voltage difference range, it is indicated that the voltage signal sent by the bluetooth master controller 101 in advance is not divided, and 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 division signal received by the bluetooth master controller 101 and the voltage value corresponding to the voltage signal sent by the bluetooth master controller 101 in advance exceeds the preset voltage difference range, it is indicated that the voltage signal sent by the bluetooth master controller 101 in advance is divided, and then 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 101 determines that the terminal device connection assembly 103 is in the data transmission working mode; if the terminal adapter 1032 is not connected to the connection adapter 1031, the bluetooth master 101 determines that the terminal connection assembly 103 is not in the data transmission operation mode.

According to the embodiment, the terminal equipment adapter 1032 is arranged, so that the terminal equipment adapter can be directly inserted into the jack of the terminal equipment when being connected with the terminal equipment, and cable connection is not needed, so that the convenience of the audio receiving equipment is improved.

As an alternative implementation, as shown in fig. 4 and 5, in another embodiment of the present application, it is disclosed that the terminal device adaptor 1032 includes: a first terminal adapter 10321 or a second terminal adapter 10322. Since only one connection adapter 1031 is provided in the present embodiment, the first terminal device adapter 10321 and the second terminal device adapter 10322 cannot be simultaneously inserted into the audio receiving apparatus, and only one of them can be selected to be inserted into the audio receiving apparatus to be connected to the connection adapter 1031. The first terminal device adaptor 10321 is provided with a first resistor R1, and the second terminal device adaptor 10322 is provided with a second resistor R2, wherein the resistance value of the first resistor R1 is different from the resistance value of the second resistor R2. Because the resistances of the two resistors are different, the voltage dividing capability of the two resistors is also different, so that the voltage value corresponding to the voltage dividing signal fed back by the first terminal device adapter 10321 after receiving the voltage signal sent by the connection adapter 1031 is necessarily different from the voltage value corresponding to the voltage dividing 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 an original voltage, the first pressure range is a voltage value range of the original voltage divided by the first resistor R1, and the second pressure range is a voltage value range of the original voltage divided by the second resistor R2. If the pressure value corresponding to the partial pressure signal sent by the connection adapter 1031 and received by the bluetooth master controller 101 is in the first pressure range, determining that the first terminal device adapter 10321 is connected with the connection adapter 1031; if the pressure value corresponding to the partial pressure signal sent by the connection adapter 1031 and received by the bluetooth master controller 101 is in the second pressure range, determining that the second terminal device adapter 10322 is connected with the connection adapter 1031; if the pressure value corresponding to the divided pressure signal sent by the connection adapter 1031 and 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, the types of the terminal device adapters are different, and the parameter information in the required audio signals may be different, so by identifying the terminal device adapter connected to the connection adapter 1031, the bluetooth master 101 may configure the parameter information in the transmitted audio signals, for example, parameters such as volume, according to the type of the connected terminal device adapter, so as to improve the matching degree between the audio signals transmitted by the bluetooth master 101 and the terminal device adapter.

The bluetooth master 101 is connected to a power supply V through a resistor R3.

Illustratively, 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 pin GPIO of the bluetooth master 101 is 1.55V, and the set first pressure range is within ±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 pin GPIO of the bluetooth master 101 is 0.28V, and the set second pressure range is within ±10% of 0.28V. When the connection adapter 1031 is a connection terminal device adapter, the voltage received by the pin GPIO of the bluetooth master 101 is 3.1V, and the original voltage is set to 3.1V. At this time, the type of the terminal equipment adapter connected to the connection adapter 1031 can be determined according to the pressure value corresponding to the partial pressure signal received by the bluetooth master controller 101.

As an alternative implementation, in another embodiment of the present application, it is disclosed that the first terminal device adapter 10321 takes as input a digital audio signal and the second terminal device adapter 10322 takes as input an analog audio signal. The bluetooth master 101 receives the digital audio signal sent by the audio transmitter, if the first terminal device adaptor 10321 is inserted into the audio receiving device and is connected with the connection adaptor 1031, the bluetooth master 101 uses the USB module integrated inside the bluetooth master 101 to directly transmit the digital audio signal to the first terminal device adaptor 10321 through the connection adaptor 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 101 converts the digital audio signal into an analog audio signal by using the ADC module integrated therein, and transmits the analog audio signal to the second terminal device adapter 10322 through the connection adapter 1031.

The device outlet 1033 is connected to the bluetooth master 101, and can connect to a terminal device through a transmission cable adapted to the device outlet 1033 and output an audio signal transmitted from the bluetooth master 101 to the terminal device. The device outlet 1033 may be an outlet to which a digital audio signal is input, or an outlet to which an analog audio signal is input.

The bluetooth master 101 may acquire a USB enumeration signal corresponding to the device socket 1033 through a USB protocol, and determine whether the device socket 1033 has a USB enumeration success according to the USB enumeration signal, if the USB enumeration is successful, it indicates that the device socket 1033 is connected to the terminal device, and if not, it indicates that the device socket 1033 is not connected to the terminal device. If the device socket 1033 is accessed to the terminal device, the bluetooth master 101 determines that the terminal device connection assembly 103 is in a data transmission working mode; if the device outlet 1033 is not connected to the terminal device, the bluetooth master 101 determines that the terminal device connection assembly 103 is not in the data transmission operation mode.

In this embodiment, the device socket 1033 may also be connected to a power supply component in the audio receiving apparatus, and charging of the power supply component in the audio receiving apparatus may be achieved through connection of the device socket 1033 to an external power supply.

The terminal device connection assembly 103 includes: a connection adapter 1031, a first terminal device adapter 10321, and a device receptacle 1033. The first terminal device adapter 10321 and the device socket 1033 both take digital audio signals as input. The first terminal device adapter 10321 is connected to the USB analog switch 106 through the connection adapter 1031. The USB analog switch 106 is connected to the bluetooth master 101 and the device outlet 1033, respectively. 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, i.e., connected to the terminal device, the first terminal device adapter 10321 sends a voltage signal carrying a preset voltage to the USB analog switch 106 through the connection adapter 1031, the voltage signal causes the USB analog switch 106 to conduct a path between the first terminal device adapter 10321 and the bluetooth master 101, and when the first terminal device adapter 10321 is not connected to the terminal device or 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, at this time, the USB analog switch 106 conducts a path between the device socket 1033 and the bluetooth master 101. When the first terminal device adapter 10321 is connected to the terminal device, the voltage value corresponding to the voltage signal received by the USB analog switch 106 is set as the preset voltage.

For example, the USB analog switch 106 in the present embodiment may be a double pole double throw switch, or a chip that can realize an analog double pole double throw switch function. As shown in fig. 7, the bluetooth master 101 is connected to the pin COM1 and the pin COM2 of the USB analog switch 106, respectively, and the digital audio signal output by the bluetooth master 101 includes a DP signal and a DM signal, the DP signal is input to the pin COM1 of the USB analog switch 106, and the DM signal is input to the pin COM2 of the USB analog switch 106.

A 5.1K resistor is provided on pin CC of first terminal device adapter 10321 and connected to GND, not shown in fig. 7.

As shown in fig. 7, when the first terminal device adapter 10321 is connected to the terminal device, the voltage value of the pin VBUS of the first terminal device adapter 10321 is 5V, the voltage is obtained by dividing the voltage by the voltage dividing circuit formed by the fourth resistor R4 and the fifth resistor R5, the voltage signal is transmitted to the pin S of the USB analog switch 106, so that the pin S of the USB analog switch 106 is set to 1, the LOGIC gate LOGIC controls the pin COM1 of the USB analog switch 106 to be connected to the pin NO1, and the pin COM2 of the USB analog switch 106 to be connected to the pin NO2, thereby realizing the conduction of the path between the first terminal device adapter 10321 and the bluetooth master 101.

When the first terminal device adaptor 10321 is connected to the terminal device and the device socket 1033 is also connected to the terminal device through the transmission cable, only the conduction of the path between the first terminal device adaptor 10321 and the bluetooth master 101 is realized, and the disconnection of the path between the device socket 1033 and the bluetooth master 101 is realized, so that the priority of the path of the first terminal device adaptor 10321 is higher than that of the device socket 1033.
