Description

Technical Field

[0001] This utility model belongs to the technical field of conference devices, specifically relating to a wireless audio and video conferencing device. Background Technology

[0002] With digital transformation, the demand for online conferencing has surged in enterprises, education, and government sectors. The widespread adoption of remote and home-based work models means that people need to participate in meetings and discussions anytime, anywhere. Traditional video conferencing systems are typically limited to fixed locations, and traditional all-in-one video conferencing terminals also suffer from problems such as insufficient microphone pickup distance and asynchronous speaker playback in large conference rooms. Furthermore, wired connections restrict device placement, affecting the aesthetics of the meeting venue and failing to meet people's needs for a good meeting experience. In addition, they can only transmit one-to-one, meaning that the input end cannot simultaneously transmit images from multiple computers, cameras, document scanners, or other devices, failing to meet the needs for simultaneous multi-device input and convenient use without cables. Utility Model Content

[0003] The purpose of this invention is to provide a wireless audio and video conferencing device that solves the technical problems of existing technologies that cannot meet the requirements of simultaneous multi-terminal input, different display needs, and convenient use without connecting cables.

[0014] Compared with the prior art, the beneficial effects obtained by this utility model are: This utility model discloses a wireless audio and video conferencing device that combines software and hardware to overcome the limitations of traditional wired transmission and achieve wireless multi-source collaborative transmission. Traditional transmission requires connecting numerous power and signal cables, making operation cumbersome and supporting only one-to-one transmission. In contrast, this product, through wireless signal transmission and reception technology, can simultaneously integrate audio, video, and image signals from multiple computers, cameras, document scanners, and other devices, achieving long-distance wireless sharing without the need for external data cables. This completely eliminates the constraints of wiring and solves the problems of clutter and limitations associated with traditional methods.

[0015] Secondly, the flexible multi-mode display control enhances scene adaptability. The receiver supports plug-and-play, and users can freely choose the display mode through the APP, including simultaneous display of multiple screens, picture-in-picture, or a single input screen, to meet the content display needs of different scenarios. Compared with the traditional fixed single display method, it greatly enhances the flexibility and practicality of operation.

[0016] Secondly, the product boasts a lightweight design and user-friendly experience. The overall design is lightweight and compact, abandoning the bulky structure of traditional equipment. Furthermore, the modular assembly (such as the modular assembly of the front and back shells) ensures both a clean and aesthetically pleasing appearance and rapid installation. Meanwhile, indicator lights provide intuitive feedback on the device's operating and connection status through different colors, flashing, or constant illumination, further lowering the barrier to entry for users.

[0017] On the other hand, it offers broad applicability and improved efficiency across various scenarios. Whether it's real-time meetings, web conferencing, or classroom teaching, features such as wireless multi-source transmission and flexible display simplify operation processes, reduce device connection time, and improve content sharing efficiency, breaking the limitations of traditional devices in application scenarios.
