Description

Technical Field

[0001] This utility model relates to the field of sound card technology, and more specifically, to a sound card with a display screen. Background Technology

[0002] Sound cards play a crucial role in audio processing, primarily used to convert sound waves into digital signals. A sound card is a fundamental component of a computer multimedia system, capable of converting raw sound signals from microphones, tapes, CDs, etc., into digital signals, which are then output to devices such as headphones and speakers, or used to produce the sounds of synthesized musical instruments via the Musical Instrument Digital Interface (MIDI).

[0003] Sound cards have a variety of functions in audio processing, including sound effects, sound quality enhancement, recording, and audio testing. These functions make sound cards important for audio recording, live streaming, and music playback, improving the efficiency and effectiveness of audio processing.

[0004] However, when we live stream on our phones, the sound card is usually connected to the phone. This can cause problems such as occupying the phone's charging port and having to look down while operating the sound card, making it impossible to see the phone screen. Therefore, we need a sound card with a built-in display that can better solve these issues. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The preferred embodiment of this utility model is a sound card with a display screen, such as... Figure 1 As shown, see also Figures 2-3 It includes a video processing module 1, a USB processing module 2, a scaler module 3, an image processing module 4, a display module 5, and an audio processing module 6;

[0029] The video processing module 1 is connected to the terminal device and is used to split the terminal device signal into a video signal and a USB signal, which are then supplied to the scaler module 3 and the USB processing module 2, respectively.

[0030] The scaler module 3 is connected to the image processing module 4 and is used to process the image. The processed image is then sent to the image processing module 4.

[0031] The image processing module 4 is connected to the display module 5 and the audio processing module 6, and is used to combine the processed image and audio data to form a display image.

[0032] Display module 5 is used to display images;

[0033] USB processing module 2 is connected to audio processing module 6 and is used to divide the USB signal into multiple signals. One USB signal is supplied to audio processing module 6 and the remaining USB signals are supplied to external devices.

[0034] Audio processing module 6 is used for audio processing;

[0035] This application connects to terminal devices such as mobile phones via a video processing module, splits the terminal device signal into a video signal and a USB signal, and supplies them to a scaler module and a USB processing module respectively. The scaler module processes the image, and the processed image is sent to an image processing module. The image processing module combines the processed image with audio data to form a display image, which is then displayed on the display module, achieving the effect of displaying the mobile phone screen on the sound card.

[0036] Meanwhile, the USB processing module divides the USB signal into multiple streams. One USB signal is supplied to the audio processing module, while the remaining USB signals are supplied to external devices, enabling functions such as power supply and signal transmission. After audio processing, the audio data is supplied to the image processing module and transmitted back to the terminal device via the USB processing module and video processing module, ensuring traditional sound processing functions. Using the sound card of this application, while ensuring the functions of a traditional sound card, it can not only display the mobile phone screen, but also provide charging and data transmission functions for external devices.

[0037] It should be noted that this solution does not involve software program improvements; each module utilizes its own inherent functionality. Figure 2 and Figure 3 The video processing module 1 and scaler module are examples of one, but other existing models can also be used; the USB processing module 2 can be implemented using an existing USB expansion dock; the image processing module 4 can be model RTD2556VD / RTD2555T, etc.; the display module 5 can be an existing display device; and the audio processing module 6 can be implemented using a traditional sound card module.

[0038] Preferably, the sound card with a display screen also includes a video capture module 7;

[0039] The video acquisition module 7 is connected to the video processing module 1 and is used to receive the video signal from the video processing module 1 and perform image acquisition.

[0040] The video processing module 1 is also used to split the video signal in the terminal device signal into two parts, which are then supplied to the scaler module 3 and the video acquisition module 7 respectively.

[0041] The system proposed in this application should effectively address the shortcomings of existing sound cards, such as consuming a large amount of mobile phone memory when recording with a mobile phone and the inability of sound cards to record live video locally.

[0042] Specifically, taking a mobile phone as an example, the working principle of the terminal device is explained as follows:

[0043] The mobile phone is connected to the video processing module 1 via a Type-C or USB interface. The video processing module 1 splits the signal into two: one goes to the scaler module 3 and the other goes to the video capture module 4. At the same time, it sends the USB signal to the USB processing module 2. The USB processing module 2 splits one USB signal into multiple signals, one of which goes to the audio processing module 6 (the original sound card module). The other signals can be used to connect a USB flash drive or a TF / SD card for the mobile phone to expand its external storage. When the video processor is connected to a power adapter, it can charge the mobile phone in reverse and also charge the internal battery of the sound card.

[0044] The audio processing module 6 receives various audio signals from the audio input interface module 8, and performs a series of audio processing steps based on button or knob operations, including sound effects, sound quality enhancement, recording, and speaker testing. The processed audio is then transmitted back to the video processing module 1 via the USB processing module 2, and the video processing module 1 sends it back to the mobile phone for live streaming. Simultaneously, the audio signal is sent to the image processing module 4 for audio analysis. Of course, the signals from the buttons and knobs are also sent to the image processing module.

[0045] The Scaler module 3 receives the video signal from the video processing module 1. The interface is not limited to HDMI, but also includes DP, Type-C, USB, etc. It performs image scaling, image cropping, and OSD menu processing before sending the signal to the image processing module 4.

[0046] The image processing module 4 receives the image from the scaler module 3. It can rotate the image and analyze the audio from the audio processing module, performing audio track analysis to generate an OSD (On-Screen Display), which is then displayed on the display module so the user can see the audio track diagram. Additionally, the image processing module can perform signal conversion. The output interface of the image processing module 4 can be an LVD, STTL, MIPI, EDP, VBO, or similar interface.

[0047] The video capture module 7 receives the video signal from the video processing module and captures the image, which can be recorded to the PC or broadcast live to major live streaming platforms via the PC.

[0048] It should be noted that buttons / knobs are not essential features. They can be replaced by displaying them on the display module using an image processing module or a UI on a scaler, and then using a touchpad for audio input control.

[0049] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
