Description

Technical Field

[0001] The present application relates to the technical field of audio signal processing, and in particular to a sound card, a sound card system, and an audio processing method for a sound card. Background Art

[0002] With the booming development of the live blogging industry, audio devices such as USB microphones / wireless microphones / sound cards are increasingly entering the homes of the general public. More live bloggers are using mobile phones with wireless microphones and USB microphones for live broadcasts. However, this live broadcast method has major flaws. Traditional sound cards generally only support microphones with Canon interfaces and 3.5mm interfaces, and are not compatible with wireless microphones and USB microphones, which makes it unable to meet the needs of current creators.

[0003] Currently, wireless microphones on the market cannot use traditional sound cards to process sound and can only transmit sound to the PC through a receiver (RX). As a result, the audio stream of the wireless microphone cannot enjoy the high-quality sound professionally processed by an external sound card. Therefore, the existing technology has defects and needs to be improved.

[0004] After the wireless microphone is connected to the sound card, the user needs to hear his or her own voice during use. At this time, a wireless monitoring device is needed to collect the sound. The commonly used wireless monitoring method on the market is to send the signal to the receiver through a wireless headset. The receiver divides the received signal into two channels. One channel is input from the physical interface of RX (USB, 3.5mm, etc.) to the terminal device (PC / phone), and the other channel is wirelessly sent to the wireless monitoring headset through the TX module in the receiver. With this design, the audio signal recorded by the wireless headset can be sent to the wireless monitoring device through two wireless transmissions. If it is used by a single user, it is still acceptable. However, if this solution is adapted to a multi-person scenario, the receiver needs to realize 1-to-2, 1-to-4 and other scenarios; limited by the bandwidth of existing wireless modules, one-to-two can still realize wireless monitoring, but one-to-many cannot be met by the existing wireless bandwidth;

[0005] Therefore, the existing technology has significant limitations and defects, and there is an urgent need for a solution that is compatible with wireless microphones and headphones. Summary of the Invention

[0041] 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.

[0042] See also Figures 1 to 3 As shown, the present application proposes a sound card system 100 , which includes a sound card 1 and at least one microphone 2 , wherein each wireless module 11 of the sound card 1 communicates wirelessly with at least one microphone 2 .

[0043] Specifically, the microphone 2 is a wireless microphone 21, and the sound card system 100 also includes at least one second monitoring device 3, each of the second monitoring devices 3 is used to communicate with one of the wireless microphones 21 by wire to realize real-time monitoring of the real-time audio data collected by the wireless microphone 21 connected thereto; or the microphone 2 is a wireless headset 22.

[0044] It can be understood that the basic function of the sound card 1 is to convert the original sound signals from the microphone, tape, CD, etc., and output the processed audio data with better sound quality to audio devices such as headphones, speakers, amplifiers, recorders, or terminal devices such as computers and mobile phones. The sound cards 1 currently on the market generally only support wired microphones 2 with XLR and 3.5mm interfaces. The wired microphones 2 are limited by the length of the wire, and there are certain inconveniences in the distance, range, and flexibility of use, resulting in a poor user experience of the wired microphones 2. The sound card system 100 provided in this embodiment can support wireless communication between each wireless module 11 of the sound card 1 and the microphone 2, and transmit the audio data received by the microphone 2 to the sound card 1 through wireless communication. In this embodiment, the microphone 2 can be a wireless microphone 21, such as Figure 2As shown, the sound card 1 can support the processing of the real-time audio data of the wireless microphone 21, so that the sound card system 100 can also process the audio data of the wireless microphone 21, so that the wireless microphone 21 can enjoy the sound effects of the professional-level sound card 1, and the use range and use distance of the wireless microphone 21 become more flexible, free from the constraints of wires, so that users do not need to worry about the range limitation caused by the length of the wires. At the same time, the sound card system 100 also includes at least one second monitoring device 3, each of which can communicate with one of the wireless microphones 21 by wire to achieve real-time monitoring of the real-time audio data collected by the wireless microphone 21 connected to it. It can be seen that the second monitoring device 3 can be a wired headset, which is inserted into the wireless microphone 21 through an interface connected to the wire, so that the second monitoring device 3 and the wireless microphone 21 can communicate by wire. Usually, during the live broadcast process, it is necessary to monitor the audio data to ensure the live broadcast effect. The second monitoring device 3 can monitor the real-time audio data collected by the wireless microphone 21 in real time through wired communication with the wireless microphone 21, that is, monitor the original audio data that has not been processed by the sound card 1. In another embodiment, the microphone 2 can also be a wireless headset 22, such as Figure 3 As shown, the microphone 2 is integrated with the earphone, the wireless headset 22 can communicate wirelessly with the sound card 1, and the sound card 1 receives the real-time audio data collected by the wireless headset for processing. At the same time, the wireless headset 22 can also monitor the collected real-time audio data in real time.

[0045] See also Figure 4 As shown, the present application proposes a sound card 1, which includes a shell 10, at least one wireless module 11 and a control module 12; the at least one wireless module 11 is arranged in the shell 10, that is, the at least one wireless module 11 is integrated on the sound card 1; the control module 12 is arranged in the shell 10, and is electrically connected to the at least one wireless module 11 to control the operation of the at least one wireless module 11.

[0046] Among them, each wireless module 11 is used to wirelessly communicate with at least one microphone 2, so that each wireless module 11 sends the real-time audio data collected by the corresponding at least one microphone 2 to the control module 12, so that the control module 12 can process the real-time audio data collected by the at least one microphone 2.

[0047] Specifically, in one embodiment, each of the wireless modules 11 is used to wirelessly communicate with at least one microphone 2, so that each of the wireless modules 11 can only send the real-time audio data collected by the corresponding at least one microphone 2 to the control module 12 in a unidirectional manner, so that the control module 12 can process the real-time audio data collected by the at least one microphone 2.

[0048] It is understood that in the live broadcast industry, the host will usually send audio data to the live broadcast device by wearing the microphone 2. The live broadcast device can be a terminal device such as a computer, mobile phone, or tablet. However, the live broadcast device does not necessarily have strong audio data processing capabilities, 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 2. The host can send the audio data to the sound card 1 by wearing the microphone 2. The sound processed by the sound card 1 is then transmitted to the live broadcast device for the audience watching the live broadcast. Currently, most sound cards 1 on the market generally support wired microphones 2. Wired microphones 2 are limited by the length of the wire, and there are certain inconveniences in terms of usage distance, range, and flexibility, resulting in a poor user experience of wired microphones 2. The sound card 1 provided in this embodiment is provided with at least one wireless module 11. Each wireless module 11 wirelessly communicates with at least one microphone 2, and the wireless module 11 also unidirectionally sends the real-time audio data collected by the at least one microphone 2 with which it is wirelessly communicating to the control module 12. The control module 12 processes the received real-time audio data. By setting the wireless module 11 to wirelessly communicate with at least one microphone 2, and the wireless module 11 can only send the real-time audio data collected by the corresponding at least one microphone 2 to the control module 12 in a unidirectional manner, so that the control module 12 completes the processing of the real-time audio data, compared with the previous sound card 1 on the market that can only support wired microphones 2, this application allows wireless microphones to use the sound card 1 and enjoy the sound effects of professional-level sound card 1, making the use range and use distance of wireless microphones more free, free from the constraints of wires, so that users do not need to worry about the range limitation caused by the length of the wires.

[0049] In addition, it should be noted that a wireless microphone generally includes a microphone 2 body and a microphone 2 receiver that wirelessly communicates with the microphone 2 body. The microphone 2 body can send the real-time audio data received by the microphone 2 to the microphone 2 receiver through wireless communication. In this embodiment, the wireless module 11 of the sound card 1 can replace the microphone 2 receiver and wirelessly communicate with at least one of the microphones 2. The microphone 2 does not need to be additionally configured with a microphone 2 receiver for matching and pairing. The sound card 1 facilitates the pairing of the microphone 2 when it leaves the factory. The user does not need to perform additional pairing after receiving the product. It can be used immediately after it is turned on, which provides a better user experience. In this embodiment, the wireless module 11 can be integrated into the sound card 1 and integrated with the sound card 1, or it can be a separate component that is connected through an interface that matches the sound card 1.

[0050] Further, see Figure 5 As shown, there is one wireless module 11, and the wireless module 11 is used for wireless communication with the four microphones 2. The wireless module 11 has four audio channels. The four audio channels serve as receiving channels for receiving the real-time audio data collected by the four microphones 2 one by one, and sending the real-time audio data collected by the four microphones 2 to the control module 12.

[0051] In this embodiment, there is one wireless module 11, and the wireless module 11 has four audio channels. The wireless module 11 communicates wirelessly with the four microphones 2. The four audio channels correspond to the four microphones 2 one by one. Each audio channel receives the real-time audio data collected by the corresponding microphone 2 and sends the real-time audio data collected by the four microphones 2 to the control module 12. By setting one wireless module 11 to correspond to four microphones 2, it is possible to connect multiple microphones 2, so that the sound card 1 can process the audio data of multiple microphones 2 at the same time, so that the sound card 1 supports simultaneous use by multiple users, expands the scope of use of the sound card 1, better meets the actual requirements of today's live broadcast industry, provides a better solution for the live broadcast industry, and provides a better user experience.

[0052] In other embodiments, the number of the wireless modules 11 may be multiple, and the wireless module 11 has four audio channels. Each of the wireless modules 11 can wirelessly communicate with one to four microphones 2. When the wireless module 11 wirelessly communicates with less than four microphones 2, its idle audio channels can also be used as transmission channels for other data.

[0053] Further, see Figure 6As shown, the real-time audio data collected by the microphone 2 is processed by the control module 12 to obtain processed audio data;

[0054] The sound card 1 further includes a first input module 13 disposed in the housing 10 and electrically connected to the control module 12 , wherein the first input module 13 is configured to generate a first control signal under user operation;

[0055] The sound card 1 further includes an audio interface 14 disposed in the housing 10 and electrically connected to the control module 12 , wherein the audio interface 14 is configured to communicate with the first monitoring device 4 via a wire.

[0056] When the sound card 1 is used to wirelessly communicate with multiple microphones 2, the control module 12 enables the first monitoring device 4 to selectively monitor the real-time audio data of the multiple microphones 2 according to the first control signal, or the control module 12 enables the first monitoring device 4 to selectively monitor the processed audio data of the multiple microphones 2 according to the first control signal, wherein the selective monitoring includes separately monitoring the real-time audio data or the processed audio data of any one of the microphones 2 in real time, and simultaneously monitoring the real-time audio data or the processed audio data of at least two of the microphones 2 in real time.

[0057] Usually during the live broadcast process, in order to ensure the live broadcast effect or facilitate communication between the live broadcast personnel, it is necessary to be able to monitor the real-time audio data or processed audio data received by the microphone 2. For example, the anchor needs to monitor the audio data processed by his own microphone 2, and other staff members need to monitor the anchor's broadcast, etc. Therefore, in this embodiment, the sound card 1 is also provided with an audio interface 14 electrically connected to the control module 12. The audio interface 14 is used for wired communication with the first monitoring device 4. The first monitoring device 4 can be a wired headset, etc. The first monitoring device 4 can insert an interface with a wire into the audio interface 14 to complete the wired communication connection with the sound card 1. It should be noted that the audio interface 14 can be one or more. When multiple audio interfaces 14 are provided, the sound card 1 supports wired communication with multiple first monitoring devices 4 at the same time. At the same time, the sound card 1 is also provided with a first input module 13 electrically connected to the control module 12. The first input module 13 can be a knob, a button or a touch screen key, etc. The user can select the audio data to be monitored through the knob, button or touch screen key. When the sound card 1 is connected to the multiple microphones 2 through wireless communication, the wireless module 11 transmits the received real-time audio data to the control module 12 for processing. The user can select the real-time audio data corresponding to one or more microphones 2 to be monitored through the first input module 13, that is, the original audio data that has not been processed by the sound card 1, or can choose to monitor the processed audio data corresponding to one or more microphones 2. By setting the audio interface 14, the sound card 1 can support access to the first monitoring device 4 and selectively monitor the pre-processed audio data and processed audio data received by one or more microphones 2, so that the sound card 1 supports simultaneous monitoring by multiple users, expands the scope of use of the sound card 1, better meets the actual requirements of today's live broadcast industry, provides a better solution for the live broadcast industry, and provides a better user experience.

[0058] Further, see Figure 7 As shown, the real-time audio data collected by the microphone 2 is processed by the control module 12 to obtain processed audio data;

[0059] The sound card 1 also includes a USB-Device interface 15 provided on the shell 10 and electrically connected to the control module 12. The USB-Device interface 15 is used to connect to the USB host 5 so that the sound card 1 can receive power and / or data from the USB host 5, and enable the sound card 1 to send the processed audio data to the USB host 5; the type of the USB-Device interface 15 is one of a USB Type-A interface, a USB Type-B interface and a USB Type-C interface.

[0060] In this embodiment, the sound card 1 is further provided with the USB-Device interface 15, which is a type of one of a USB Type-A interface, a USB Type-B interface, and a USB Type-C interface, and can be connected to a corresponding USB host 5 having one of a USB Type-A interface, a USB Type-B interface, and a USB Type-C interface, such as a computer, a mobile phone, etc., so that the USB host 5 can power the sound card 1 or exchange data with the USB host 5, and can also send audio data processed by the sound card 1 to the USB host 5. By providing the USB-Device interface 15, the sound card 1 can exchange data with the USB host 5, thereby expanding the scope of use of the sound card 1, providing a better solution, and improving the user experience.

[0061] Further, see Figure 8 As shown, the sound card 1 also includes a second input module 16 provided in the housing 10 and electrically connected to the control module 12. The second input module 16 is used to generate different second control signals under the operation of the user. The control module 12 implements different functions of the sound card 1 according to different second control signals. The functions include at least one of the power on and off function, volume adjustment function, noise reduction, reverberation and voice change processing functions. It can be understood that the second input module 16 can also be a knob, a button or a touch screen key, etc. The user can select the required function through the knob, button or touch screen key, so that the sound card 1 performs one or more of the power on and off function, volume adjustment function, noise reduction, reverberation and voice change processing functions. By providing the second input module 16, the user can complete the setting and control of the sound card 1 by operating the second input module 16, which is convenient for the user to use and provides a better user experience.
