Technical Field
[0001] This utility model relates to the field of microphone technology, and more specifically, to a two-way audio and video transmission microphone based on network communication. Background Technology
[0002] In the field of multimedia communication and audio / video processing technology, existing audio / video equipment often requires the separate installation of multiple cables, including power cables, audio cables, video cables, and network cables. This not only increases the complexity of installation and maintenance but also limits the flexibility and aesthetics of the equipment. Furthermore, with the rise of applications such as remote video conferencing, online education, telemedicine, and cross-language communication, the demand for communication equipment capable of simultaneously achieving bidirectional audio and video transmission, as well as integrating cameras and displays, has surged. Such equipment not only needs efficient audio and video processing capabilities but also needs to support headset access to provide a more private and clear voice communication environment when needed.
[0003] To address these issues, PoE (Power Over Ethernet) technology allows for the simultaneous transmission of data and power over Ethernet cables, significantly simplifying device cabling and installation, reducing costs, and improving system reliability. However, most existing PoE devices on the market focus on optimizing single functions, such as supporting only audio or video transmission, lacking comprehensive solutions. Utility Model Content
[0004] The purpose of this invention is to provide a network-based microphone for bidirectional audio and video transmission, integrating PoE power supply and communication, bidirectional audio transmission, and bidirectional video transmission into one microphone device, providing users with an efficient, convenient, and comprehensive audio and video communication solution.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] The camera and touchscreen are both connected to the processor.
[0008] The system includes a switch chip, an Ethernet PHY chip, and a network audio module. The Ethernet PHY chip and the network audio module are connected to the switch chip, and the Ethernet PHY chip is connected to the processor.
[0009] An audio processing chip and an electret condenser microphone are connected together, with the audio processing chip connected to a network audio module.
[0010] The PoE power supply module connects to the switch chip via a network port connector.
[0011] The beneficial effects of this utility model are as follows: In this solution, a PoE power supply module is connected via a network port. This interface is not only used for audio and video data transmission, but also receives power from an external network switch via PoE technology to provide operating power for the entire device. The equipped electret condenser microphone is connected to an AES67 protocol network audio module via an audio processing chip to realize the acquisition, processing, and output of audio signals to an external network. The camera is connected to the processor via a MIPI interface, and the touch screen is connected to the processor via an RGB interface. The camera is responsible for capturing video signals, and the touch screen is used to display local or remote video content. After processing the video stream, the processor exchanges data and communicates with the external network via a switch chip. After the entire device is connected to the network and receives PoE power, the processor loads the operating system and application from the internal storage unit to complete the device startup and initialization process. The device will automatically detect and configure the network connection to ensure uninterrupted audio and video transmission.
[0012] In this solution, during actual use, the microphone captures local audio signals, which are then encoded and compressed by the audio processing chip before being sent to the switch chip. Simultaneously, the switch chip receives remote audio signals from the network and plays them on the headphones after passing through the audio processing chip. In addition, the camera captures video signals, which are encoded by the processor and then sent to the switch chip. The processor can also process video streams from external networks and display them on the screen. It is worth mentioning that the video information captured by the camera can also be displayed on the touch screen.

At the same time, the device also receives the audio and video data from the remote device from the network, realizing two-way real-time communication. In addition, users can perform device configuration, volume adjustment, video switching and other operations through the touch screen or expansion interface.
[0014] On the basis of the above technical solution, the present invention can also be improved as follows.
[0015] Furthermore, the aforementioned audio processing chip is also connected to an earphone jack for connecting external headphones.
[0016] The beneficial effect of adopting the above-mentioned further solution is that the device is equipped with a headphone jack on the side, which is connected to a network module with the AES67 protocol through an audio processing chip to collect audio signals from the external network.
[0017] Furthermore, the aforementioned network port is an RJ45 network port.
[0018] Furthermore, the above also includes the main structure for mounting or accommodating processors, cameras, touch screens, switch chips, Ethernet PHY chips, network audio modules, audio processing chips, electret condenser microphones, PoE power supply modules, network port sockets, and headphone sockets.

[0021] Furthermore, the processor is also connected to a TYPE-C interface, which is located on the side wall of the mounting base.
[0022] The advantages of adopting the above-mentioned further solutions are: the surface touch screen and expansion interfaces such as TYPE-C are used for user operation, device configuration and connection with other devices.
[0023] Furthermore, the connecting part is fixedly connected to the mounting base, and the connecting part is rotatably connected to the user part.
[0024] Furthermore, the aforementioned touchscreen is tilted towards the user.
[0025] Furthermore, one end of the aforementioned user section forms a microphone pickup bar for mounting an electret condenser microphone, and the upper end of the user section is connected to a camera.
[0026] Furthermore, the aforementioned camera is located within a strip-shaped groove in the user section, and the camera is rotatably connected to the inner wall of the strip-shaped groove via a bracket.
