In the wireless audio equipment solution, the audio information needs to be processed in advance to convert the analog signal into a digital signal before sending it. In this way, the transmission of audio information requires a wider radio frequency band, which is easily affected by external radio frequency interference. In addition, digital modulation is prone to generate stray signals, and the sound is prone to delay, which makes the sound sound unnatural during the meeting.

[0067] The second wireless communication unit 14 has an output end connected to the wireless input end of the conversion module 20 . The second wireless communication unit 14 is used to access a second wireless audio device and transmit a second wireless audio signal.

[0068] In this embodiment, the communication module 10 includes a first wired communication unit 11, a first wireless communication unit 12, a second wired communication unit 13, and a second wireless communication unit 14. Among them, the first wired communication unit 11 and the second wired communication unit 13 are connected to a wired audio device, and the first wired audio device and the second wired audio device can be audio devices connected by wire, and there is no necessary difference between the two, and they can even be the same device; the first wireless communication unit 12 and the second wireless communication unit 14 are connected to a wireless audio device, and the first wireless audio device and the second wireless audio device can be audio devices connected by wireless, and there is no necessary difference between the two, and they can even be the same device.

The descriptions of wired and wireless in the first wired audio signal, the second wired audio signal, the first wireless audio signal, and the second wireless audio signal refer to the type of signal, which is used to distinguish whether it is an audio signal output by a wired audio device or an audio signal output by a wireless audio device, rather than referring to the transmission method of the signal.

[0074] In this embodiment, each communication unit is also connected to the communication terminal of the main control chip. The specific connection method can be through a bus connection, or each communication unit can be connected to multiple communication terminals of the main control chip 40 respectively, depending on the actual design and the selected main control chip 40. When each communication unit is connected to an audio device, the communication unit will output a communication signal to the main control chip 40. The function of the communication signal is to enable the main control chip 40 to determine which communication unit is connected to the audio device, thereby controlling the transmission path of the communication unit connected to the inside of the conversion module 20 to be turned on. Specifically, when the first wired communication unit 11 is connected to a wired audio device, the first wired communication unit 11 outputs a first communication signal to the main control chip 40. Since the first wired communication unit 11 is connected to the wired input end of the conversion module 20, the main control chip 40 outputs a first control signal according to the first communication signal to turn on the transmission path where the wired input end is located; when the first wireless communication unit 12 is connected to a wireless audio device, the first wireless communication unit 12 outputs a second communication signal to the main control chip 40.

Since the second wired communication unit 13 is connected to the wired-to-wireless input terminal of the conversion module 20, the main control chip 40 outputs a third control signal according to the third communication signal to turn on the transmission path where the wired-to-wireless input terminal is located; when the second wireless communication unit 14 is connected to the wireless audio device, the second wireless communication unit 14 outputs a fourth communication signal to the main control chip 40. Since the second wireless communication unit 14 is connected to the wireless input terminal of the conversion module 20, the main control chip 40 outputs a fourth control signal according to the fourth communication signal to turn on the transmission path where the wireless input terminal is located.

[0075] Reference Figure 4 In some feasible embodiments, the conversion module 20 includes:

[0076] A first stream switch 21, wherein a first end of the first stream switch 21 is used as a wired input end of the conversion module 20 and is connected to the first wired communication unit 11, and a second end of the first stream switch 21 is used as a wired output end of the conversion module 20 and is connected to a wired input end of the sound card module 30;

[0077] A first conversion switch 22, wherein a first end of the first conversion switch 22 is used as a wireless-to-wired input end of the conversion module 20 and is connected to the first wireless communication unit 12, and a second end of the first conversion switch 22 is connected to a third end of the first flow switch 21;

[0080] In this embodiment, the conversion module 20 includes a first stream switch 21, a first conversion switch 22, a second stream switch 23, and a second conversion switch 24. The first conversion switch 22 is used to convert the wireless audio signal output by the wireless audio device into a wired audio signal; the second conversion switch 22 is used to convert the wired audio signal output by the wired audio device into a wireless audio signal. The first end to the second end of the first stream switch 21 constitutes a first transmission path; the first conversion switch 22 and the third end to the second end of the first stream switch constitute a second transmission path; the second conversion switch 24 and the third end to the second end of the second stream switch 23 constitute a third transmission path; the first end to the third end of the second stream switch 23 constitutes a fourth transmission path; wherein the first transmission path and the second transmission path respectively transmit the audio signal of the wired audio device and the audio signal of the wireless audio device to the wired input end of the sound card module 30; the third transmission path and the fourth transmission path respectively transmit the audio signal of the wired audio device and the audio signal of the wireless audio device to the wireless input end of the sound card module 30. It can be understood that compared with the traditional solution in which the wired signal end of the sound card module 30 can only be connected to the wired communication unit, and the wireless signal end can only be connected to the wireless communication unit, the first conversion switch 22 and the second conversion switch 24 in this embodiment convert the wired audio signal and the wireless audio signal, so that the wired signal end and the wireless signal end of the sound card module 30 can be connected to both the wired communication unit and the wireless communication unit, thereby making more effective use of the port resources of the sound card module 30.

[0084] When the main control chip 40 outputs the second control signal, the second end and the third end of the first stream switch 21 are turned on, and the first conversion switch 22 is turned on, and the first conversion switch 22 converts the first wireless audio signal into a third wired audio signal and outputs it from the wired output end;

[0085] When the main control chip 40 outputs the third control signal, the second end and the third end of the second stream switch 23 are turned on, and the second conversion switch 24 is turned on, and the second conversion switch 24 converts the second wired audio signal into a third wireless audio signal and outputs it from the wireless output end;

[0086] When the main control chip 40 outputs the fourth control signal, the first end and the second end of the second stream switch 23 are turned on, and the second wireless audio signal is output from the wireless output end.

[0087] In this embodiment, the first wired audio signal, the second wired audio signal and the third wired audio signal are all wired audio signals of the same type, but the devices that send these signals may be different and use different names; the first wireless audio signal, the second wireless audio signal and the third wireless audio signal are all wireless audio signals of the same type, but the devices that send these signals may be different and use different names. When the first wired communication unit 11 is connected to a wired audio device, the wired audio signal output by the wired audio device should be input to the wired input end of the sound card module. Therefore, the main control chip 40 outputs a first control signal to turn on the first end and the second end of the first stream switch 21, so that the wired audio signal is transmitted to the wired input end of the sound card module 30 through the first stream switch 21; when the first wireless communication unit 12 is connected to a wireless audio device, in order to input the wireless audio signal output by the wireless audio device to the wired input end of the sound card module 30, it is necessary to convert the wireless audio signal output by the wireless audio device into a wired audio signal. Therefore, the main control chip 40 outputs a second control signal to turn on the first conversion switch 22, and turn on the second end and the third end of the first stream switch 21. The wireless audio signal is converted into a wired audio signal inside the first conversion switch 22, and then transmitted to the wired input end of the sound card module 30 through the first stream switch 21; when When the second wireless communication unit 14 is connected to a wireless audio device, the wireless audio signal output by the wireless audio device should be input to the wireless input end of the sound card module 30. Therefore, the main control chip 40 outputs a fourth control signal to turn on the first end and the second end of the second stream switch 23, so that the wireless audio signal is transmitted to the wireless input end of the sound card module 30 through the second stream switch 23; when the second wired communication unit 13 is connected to a wired audio device, in order to input the wired audio signal output by the wired audio device into the wireless input end of the sound card module 30, it is necessary to convert the wired audio signal output by the wired audio device into a wireless audio signal. Therefore, the main control chip 40 outputs a third control signal to turn on the second conversion switch 24, and turn on the second end and the third end of the second stream switch 23. The wired audio signal is converted into a wireless audio signal inside the second conversion switch 24, and then transmitted to the wireless input end of the sound card module 30 through the second stream switch 23.

[0088] It is worth adding that, in this embodiment, there are only two ways of conducting the first flow switch 21 and the second flow switch 23, namely, the first end is conducted with the second end or the second end is conducted with the third end. Therefore, only one of the first wired communication unit 11 and the first wireless communication unit 12 can transmit an audio signal to the sound card module 30 at the same time; only one of the second wired communication unit 13 and the second wireless communication unit 14 can transmit an audio signal to the sound card module 30 at the same time. To implement the above embodiment, the main control chip 40 is set with a priority determination, and the latter priority principle is implemented. For example, when the first wired communication unit 11 sends a first communication signal, the main control chip 40 controls the first end and the second end of the first flow switch 21 to be conducted. At this time, when the first wireless communication unit 12 sends a second communication signal again, the main control chip 40 controls the second end and the third end of the first flow switch 21 to be conducted, and the first end and the second end are cut off.

[0089] In some feasible embodiments, the first wired communication unit 11, the first wireless communication unit 12, the second wired communication unit 13 and the second wireless communication unit 14 include indicator lights, the communication end of the main control chip 40 outputs an indication signal, and the indicator lights are activated according to the indication signal.

[0090] In this embodiment, the signal interaction between the main control chip 40 and each communication unit is not only used to determine whether an audio device is connected, but also to perform other signal interactions. In this embodiment, each communication unit is provided with an indicator light to indicate whether the audio device connected to the communication unit is connected normally, so that the audio signal is finally transmitted to the main control chip 40, so that the main control chip 40 can pick up the sound normally. The signal interaction between the main control chip 40 and the communication unit can be set according to actual needs.

[0095] In some feasible embodiments, the first flow switch 21 and the second flow switch 23 include integrated circuit chips.

[0096] In this embodiment, the first stream switch 21 and the second stream switch 23 only need to be controllable by the main control chip 40 , and digital switches are preferred.

[0097] The embodiment of the present application provides a sound card port expansion device, which uses a conversion switch and a flow switch, and performs a clever circuit design, so that the wired input end and the wireless input end of the sound card module can achieve compatibility with connecting wired audio devices or wireless audio devices, and realize the dynamic allocation of the sound card port, which solves the problem of port resource waste when the remaining audio input port of the sound card module does not match the type of audio device to be connected. Furthermore, the dynamic allocation of the sound card port allows the sound card module to have more combinations of devices that can be connected, making it easier to meet actual needs. Further, the present application also expands the information interaction between the communication unit and the main control chip, facilitating other in-depth interactions between the two, such as two-way information interaction, identification of device types, and other operations, making up for the defect that the related scheme can only singlely determine whether the communication unit is connected to the audio device.
