More live streaming bloggers are using mobile phones with wireless microphones and USB microphones for live streaming. However, traditional sound cards generally only support microphones with Canon and 3.5mm interfaces, and are not compatible with wireless microphones and USB microphones, which makes them unable to meet the needs of current creators.

[0045] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0046] See also Figure 1 As shown, the present application proposes a sound card system 2 , which includes a sound card 1 and a plurality of microphones 4 . The microphones 4 are connected to the interfaces 22 of the interface assembly 21 of the sound card 1 in a one-to-one correspondence.

[0047] It is understandable that with the popularization of network technology, the live broadcast industry has also been booming. During the live broadcast process, live bloggers usually use mobile phones, tablets, computers and other terminal devices with microphones to broadcast live. In order to make the broadcast effect better, more requirements are put forward for the processing of audio data, such as reverberation processing, noise reduction processing, voice change processing, etc. In order to meet the processing requirements of audio data, a sound card is usually used to process the audio data received by the microphone. During the live broadcast process, sometimes it is not just one anchor who broadcasts live, and there may be multiple anchors during the live broadcast process. The sound card system 2 of this embodiment can support multiple anchors to connect their own microphones 4 to the sound card 1 at the same time. The interface 22 of the interface component 21 of the sound card 1 is connected to multiple microphones 4 in a one-to-one correspondence. The sound card 1 can process the audio data of multiple microphones 4 at the same time, and process the audio data of different microphones 4 according to different effect requirements. It can be seen that by connecting the microphone 4 to the interface 22 of the interface component 21 of the sound card 1 one by one, the sound card 1 can process the audio data of multiple microphones 4 at the same time, thereby expanding the scope of use of the sound card system 2, better meeting the actual requirements of today's live broadcast industry, providing a better solution for the live broadcast industry, and providing a better user experience.

[0048] See also Figure 2As shown, the present application also proposes a sound card assembly 3, which includes multiple sound cards 1. The multiple sound cards 1 can be connected through the interface 22 of the interface assembly 21 of the sound card 1, and the control modules 30 of the multiple sound cards 1 process the real-time audio data collected by the microphone 4 separately and / or sequentially, so that the sound card assembly 3 outputs the processed audio data, and the processing method of each sound card 1 for the real-time audio data collected by the microphone 4 includes at least one of reverberation processing, noise reduction processing, and voice change processing.

[0049] Usually, for different live broadcast needs, the host's requirements for audio data processing will be different. When one sound card cannot meet the user's demand for sound effects, the sound card component 3 provided in this embodiment can connect multiple sound cards 1 through the interface 22 of the interface component 21 of the sound card 1. Different sound cards 1 can perform different effect processing on audio data. The control modules 30 corresponding to the multiple sound cards 1 can perform at least one of reverberation, noise reduction, and voice change on the audio data of different microphones 4 according to different effect processing requirements, and can also perform reverberation, noise reduction, voice change, etc. on the audio data of one microphone 4 in sequence.

[0050] The following is an explanation of the sound card assembly 3 including three sound cards 1 with different sound effect processing capabilities. The three sound cards 1 can perform reverberation processing, the second one can perform noise reduction processing, and the third one can perform voice change processing. When the real-time audio data collected by the microphone 4 needs to be reverberated, the first sound card 1 processes the audio data, and the second and third sound cards 1 do not process it. When the audio data needs to be noise reduced, the second sound card 1 processes the audio data, and the first and third sound cards 1 do not process it. When the audio data needs to be voice changed, The third sound card 1 processes the audio data, while the first and second sound cards 1 do not process it. In addition, the audio data can also be processed in sequence by multiple sound cards 1 in the sound card assembly 3 to achieve a variety of sound effects. For example, when the real-time audio data collected by the microphone 4 needs to be reverberated and noise reduced, the first and second sound cards 1 process the audio data in sequence, while the third sound card 1 does not process it. When the real-time audio data collected by the microphone 4 needs to be reverberated, noise reduced, and voice-changed, the three sound cards 1 process the audio data in sequence.

[0051] The connection is made through the interface 22 of the interface component 21 of the sound card 1, and the control modules 30 of the multiple sound cards 1 process the real-time audio data collected by the microphone 4 separately and / or sequentially, so that the sound card component 3 can perform different sound effect processing on the audio data of the multiple microphones 4, or perform multiple sound effect processing on the audio data of the multiple microphones 4, so that the sound card component 3 can better meet the actual needs of today's live broadcast industry, provide a better user experience, and provide a better solution for the live broadcast industry.

[0052] See also Figures 3 and 4 The sound card 1 in the above embodiment includes a housing 10 , a communication module 20 and a control module 30 .

[0053] The communication module 20 is arranged in the shell 10, and the communication module 20 includes at least one interface component 21, each of the interface components 21 includes at least one interface 22 that complies with the digital signal transmission protocol; and the control module 30 is arranged in the shell 10 and is electrically connected to the interface component 21; wherein, the at least one interface 22 of all the interface components 21 is used to be connected one-to-one with at least one microphone 4, so that the sound card 1 can receive real-time audio data from the at least one microphone 4, and thereby enable the control module 30 to process the real-time audio data collected by the at least one microphone 4.

[0054] It can be understood that the sound card 1 of this embodiment has at least one interface component 21, and each interface component 21 corresponds to at least one interface 22, wherein the interfaces 22 are all interfaces that comply with the digital signal transmission protocol. At least one microphone 4 can be connected one by one to at least one interface 22, so that the audio data received by the microphone 4 is received by the interface component 21 and sent to the communication module 20, and then sent to the control module 30 by the communication module 20, so that the control module 30 can process the real-time audio data collected by the microphone 4 separately. Since the interfaces 22 are all interfaces that comply with the digital signal transmission protocol, they can be adapted to most of the microphones 4 on the current market. When using the sound card 1, users can use the sound card 1 without replacing their existing microphone 4, thereby solving the problem that the sound card is not compatible with microphones of different brands and different transmission protocols. When users perform live broadcasts, they do not need to replace the existing microphones, and can use the existing microphones for live broadcasts, saving users' live broadcast costs and providing a better user experience, providing a better solution for the live broadcast industry.

[0055] Further, see Figure 5As shown, the digital signal transmission protocol includes a USB parallel communication protocol; in each of the interface components 21, when the at least one interface 22 complies with the USB parallel communication protocol, the at least one interface 22 includes a first USB-HOST interface 24 for connecting the microphone 4, and the type of the first USB-HOST interface 24 is at least one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface; the microphone 4 is at least one of a wired microphone 41 and a wireless microphone 42; the wireless microphone 42 is a 2.4G wireless microphone or a UHF wireless microphone, and the wireless microphone 42 includes a wireless microphone body 44 and a microphone receiver 43 that wirelessly communicates with the wireless microphone body 44, and the microphone receiver 43 is used to connect to the corresponding interface 22; the real-time audio data collected by the microphone 4 is processed by the control module to obtain processed data. The interface 22 in the interface component 21 is also used to connect the headset 5 to monitor the processed data; in each interface component 21, when the at least one interface 22 complies with the USB parallel communication protocol, the at least one interface 22 also includes a second USB-HOST interface 25 for connecting the headset 5, and the type of the second USB-HOST interface 25 is at least one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface; the headset 5 is at least one of a wired headset 51 and a wireless headset 52; the wireless headset 52 is a 2.4G wireless headset or a UHF wireless headset, and the wireless headset 52 includes a wireless headset main body 54 and a headset receiver 53 that wirelessly communicates with the wireless headset main body 54, and the headset receiver 53 is used to connect to the corresponding interface 22.

[0056] It can be understood that the basic function of a sound card is to convert the original sound signals from a microphone, tape, CD, etc., and output them to audio devices such as headphones, speakers, amplifiers, and recorders. In the live broadcast industry, the host usually wears the microphone 4 to send audio data to the live broadcast device. The live broadcast device can be a terminal device such as a computer, mobile phone, or tablet. However, the terminal device may not have the ability to process audio data, and live broadcasting has certain requirements for sound effects. Therefore, the sound card 1 provided in this embodiment can be used to process the audio data received by the microphone 4. The host can wear the microphone 4 to send the audio data to the sound card 1, and then the sound processed by the sound card 1 is transmitted to the live broadcast device for playback to the audience watching the live broadcast.

[0057] It should be noted that the digital signal transmission protocol includes a serial communication protocol and a parallel communication protocol, wherein the serial communication protocol includes the RS-232 serial communication protocol, the RS-485 serial communication protocol, the I2C serial communication protocol, and the SPI serial communication protocol; the parallel communication protocol includes the IEEE 1394 parallel communication protocol and the USB parallel communication protocol. In this embodiment, the digital signal transmission protocol is the USB parallel communication protocol.

[0058] In this embodiment, the at least one interface 22 complies with the USB parallel communication protocol, and the at least one interface 22 includes a first USB-HOST interface 24 for connecting the microphone 4, and the type of the first USB-HOST interface 24 is at least one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface, that is, when the interface component 21 includes only one interface 22, the type of the first USB-HOST interface 24 is one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface; when the interface component 21 includes only multiple interfaces 22, or there are multiple interface components 21, the type of the first USB-HOST interface 24 is one or more of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface.

[0059] Typically, during a live broadcast, the processed data needs to be monitored to ensure the live broadcast effect. In order not to affect the audio data received by the microphone 4, and at the same time, the host can clearly hear the real-time sound or the processed sound to facilitate the live broadcast, the host can usually choose to listen to the real-time audio data or the sound processed by the sound card 1 by wearing headphones 5. In this embodiment, the sound card 1 includes not only the first USB-HOST interface 24 for connecting to the microphone 4, but also the second USB-HOST interface 25 for connecting to the headphones 5, thereby forming a complete live broadcast solution system of the microphone 4, the sound card 1, and the headphones 5.

[0060] Since the traditional wired microphone 41 is mostly a wired microphone with a Canon interface and a 3.5mm interface or a wired microphone with a USB interface 22, the wired microphone is limited by the length of the wire, and there are certain inconveniences in the use distance, range and flexibility, resulting in a poor user experience of the wired microphone. In this embodiment, the type of the first USB-HOST interface 24 is at least one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface, so the wired microphone 41 is a wired microphone 41 with a wire and a USB interface, and the wireless microphone 42 is usually a 2.4G wireless microphone or a UHF wireless microphone, and the wireless microphone 42 includes the wireless microphone body 44 and a microphone receiver 43 that wirelessly communicates with the wireless microphone body 44, and the microphone receiver 43 has a USB interface. In this embodiment, the first USB-HOST interface 24 can be compatible with connecting one or more of the wired microphone 41 and the wireless microphone 42, that is, the sound card 1 is provided with an interface 22 supports connecting a wired microphone 41 or a wireless microphone 42. The sound card 1 is provided with multiple interfaces 22 and supports connecting a wired microphone 41 and a wireless microphone 42 at the same time. The wired microphone 41 is connected to the first USB-HOST interface 24 through a wired USB interface, and the USB interface of the microphone receiver 43 of the wireless microphone 42 is connected to the corresponding first USB-HOST interface 24. The wireless microphone body 44 communicates wirelessly with the microphone receiver 43. In this way, the sound card 1 can support the use of both the wired microphone 41 and the wireless microphone 42. In this embodiment, the at least one interface 22 also includes a second USB-HOST interface 25 for connecting the headset 5. Similarly, the sound card 1 can be connected to one or more of a wired headset 51 and a wireless headset 52 through the second USB-HOST interface 25, that is, the sound card 1 supports the connection of a wired headset 51 and a wireless headset 52, the wired headset 51 is connected to the second USB-HOST interface 25 through a wired USB interface, and the USB interface of the headset receiver 53 of the wireless headset 52 is connected to the corresponding second USB-HOST interface 25, and the wireless headset body 54 communicates wirelessly with the headset receiver 53. In this way, the sound card 1 can support the use of both the wired headset 51 and the wireless headset 52.Compared with the previous wireless microphones 42 on the market that can only be directly connected to PCs, mobile phones and other terminals, and cannot further optimize the sound through the sound card 1, this application allows the wireless microphone 42 to also use the sound card 1 and enjoy professional-grade sound effects. At the same time, the support for the wireless headphones 52 and the wireless microphone 42 makes the use range and distance of the sound card 1 more flexible and free from the constraints of wires. During live broadcasts, the microphone receiver 43 of the wireless microphone 42 only needs to be inserted into the first USB-HOST interface 24 of the sound card 1, and the sound of the wireless microphone 42 is received by the microphone receiver 43 and fed back to the sound card 1, so that the user does not need to worry about the range limitation caused by the length of the wire. In addition, the sound card 1 is compatible with all USB wired microphones 41 and wireless microphones 42 on the market, and does not require additional configuration during use. It is plug-and-play and has a better user experience.

[0061] It should be noted that the interface type of the first USB-HOST interface 24 and the second USB-HOST interface 25 connected to the USB interface can be at least one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface. The USB-A interface is the most common type of USB interface. Its pin definition includes VCC, D-, D+ and GND. It supports multiple transmission protocols from USB 1.0 to USB 3.2, and the transmission speed ranges from 1.5Mbps to 5Gbps. Although the USB-B interface is less common in modern computers, it is still used in some professional equipment. Its pin definition is similar to that of USB-A and supports transmission protocols from USB 1.1 to USB2.0. The USB-C interface is widely used in modern smartphones, laptops and other devices. It supports high-speed data transmission and charging, and is compatible with Thunderbolt3 and USB4 standards. The pin design of the USB-C interface makes it suitable for thinner devices such as MacBooks and mobile phones. As can be seen from the above, by setting the first USB-HOST interface 24 and the second USB-HOST interface 25, the sound card 1 can be connected to the wired microphone 41, wireless microphone 42, wired headset 51, and wireless headset 52 of the USB interface. Therefore, it can be compatible with wired microphones 41, wireless microphones 42, wired headset 51 and wireless headset 52 of different brands and different interfaces, so that users do not need to purchase specific microphones 4 or headsets 5. While solving the problem that the use of the wired microphone 41 and the wired headset 51 cannot be separated from the constraints of wires and is not free to use, it also solves the problem that the existing sound card 1 can only use the wireless microphone 42 and wireless headset 52 that are paired with it, and is not compatible with all microphones 4 or headsets 5 with other interfaces such as the user's existing or most wireless microphones 42 or wireless headsets 52 on the market. Therefore, the sound card 1 has a wider range of use, stronger market competitiveness, and better user experience.

[0065] It should be noted that when the sound card 1 includes multiple interface components 21, and each interface component 21 includes a first USB-HOST interface 24, the first USB-HOST interfaces 24 in different interface components 21 of the sound card 1 can be used to connect microphones of different brands, thereby improving the compatibility of the sound card 1. When the sound card 1 includes multiple interface components 21, and each interface component 21 includes multiple first USB-HOST interfaces 24, the different interface components 21 of the sound card 1 can be used to connect microphones of different brands, and multiple first USB-HOST interfaces 24 in the same interface component 21 can be used to connect multiple microphones of different models within the same brand, or can be used to connect multiple microphones of the same model within the same brand, thereby improving the compatibility of the sound card 1.

[0074] Further, see Figures 9 to 11 The present application also proposes an audio processing method for the sound card 1. The control module 30 can execute the audio processing method to control the sound card 1. The audio processing method includes the following steps:

[0075] Step S1: When the interface 22 of the interface component 21 is connected to the microphone 4, the type of the microphone 4 is detected to determine the type of the microphone 4; if the microphone 4 is determined to be a wired microphone 41, step S21 is executed; if the microphone 4 is determined to be a wireless microphone 42, step S22 is executed;

[0076] In step S1 , the user inserts an audio device, such as a wired microphone 41 or a microphone receiver 43 of a wireless microphone 42 , into the first USB-HOST interface 24 , and the USB-HOST controller 34 initiates an enumeration test on the type of the microphone 4 to determine the type of the microphone 4 .

[0077] Step S21: loading the first driver;

[0078] If the microphone 4 is a wired microphone 41 with a USB interface 22, the first driver is loaded. In this embodiment, the first driver is a UAC driver. The UAC driver refers to a driver designed for audio devices that comply with the USB Audio Class (UAC) standard, and is used to implement communication and data transmission functions with USB audio devices in the operating system.

[0079] Step S22: loading the second driver;

[0080] If the microphone 4 is a wireless microphone 42 , the second driver is loaded. In this embodiment, the second driver is a HID driver, which is a standardized driver for managing communication between a human-computer interaction device and a computer system.

[0081] Step S3: receiving the real-time audio data collected by the microphone 4 and performing audio processing on the real-time audio data collected by the microphone 4.

[0082] Specifically, the receiving of the real-time audio data collected by the microphone 4 and performing audio processing on the real-time audio data collected by the microphone 4 further includes the following steps:

[0085] Step S32: Processing the real-time audio data collected by the microphone 4 and obtaining a processed audio stream;

[0086] Specifically, when the interface 22 of the interface component 21 is connected to the microphone 4 , the detection processing unit 31 processes the real-time audio data collected by the microphone 4 and obtains a processed audio stream.

[0087] Step S33: Process the audio stream;

[0088] Specifically, the audio processing unit 32 performs reverberation processing, noise reduction processing, or voice modification processing on the processed audio stream obtained after being processed by the detection processing unit 31 .

[0089] In this embodiment, the processing of the real-time audio data collected by the microphone 4 and obtaining the processed audio stream further includes the following steps:

[0090] Step S321: converting the real-time audio data collected by the microphone 4 into a PCM audio stream;

[0093] It should be noted that in step S21 and step S22, if different interfaces 22 are connected to different microphones 4, such as some interfaces 22 are connected to the wireless microphone 42 and some interfaces 22 are connected to the wired microphone 41, the sound card 1 can execute the first drive and the second drive at the same time.
