Technical Field
[0001] This utility model relates to the field of intelligent conference equipment technology, specifically to an AI voice-controlled wireless conference microphone system without a central control unit. Background Technology
[0002] In conference systems for small and medium-sized meeting rooms, voice control and device linkage functions typically rely on a central control system. However, a common problem with existing technologies is the high deployment cost and complex maintenance of central control systems. Traditional conference microphone systems often require wired connections to work with central control equipment, which involves cumbersome wiring and debugging processes, increasing the workload for installation and maintenance.
[0003] Specifically, in small and medium-sized conference room applications, users have higher requirements for the ease of operation and functional integration of conference equipment. However, due to the complex hardware architecture of the central control module in traditional systems, the linkage between devices relies on fixed logical configurations, resulting in a less intuitive operation process and potentially high learning costs for users. Furthermore, the high procurement and maintenance costs of central control systems make it difficult for small and medium-sized enterprises with limited budgets to widely adopt efficient conference solutions.
[0004] Chinese patent (authorization announcement number CN201910345678X) discloses a conference microphone system based on wireless transmission, which realizes the connection between the conference microphone and audio equipment through wireless communication technology. It has the advantage of reducing wiring complexity and can improve the flexibility and portability of the conference system to a certain extent.
[0005] However, in practical applications, the above structure lacks intelligent voice control functions, and users still need to rely on manual operation to complete device linkage, which limits the system's adaptability in efficient meeting management and prevents the efficiency of device switching and function adjustment during the meeting from being significantly improved.

[0017] This utility model has the following beneficial effects:
[0018] 1.

The status monitoring module monitors the operating status of external devices in real time and immediately sends a fault alert signal to the signal processing module upon detecting any abnormality.
[0035] The above embodiments describe in detail the specific implementation of this utility model. Through the coordinated work of the pickup component, signal processing module, transmission module, and linkage interface unit, the efficient operation of the wireless conference microphone system without a central control unit is achieved. The structural design of the pickup cavity 2 and the anti-interference cover 4, combined with the spiral arrangement of the guide hole 3, the guide slope, and the multiple noise reduction effects of the buffer cavity, reduces interference from external wind noise and environmental noise. The design of the adjustment knob 5 combined with the pickup cavity 2 allows for flexible adjustment of the acoustic feedback effect by changing the position of the damping plate by rotating the adjustment knob 5.

[0036] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.
[0037] In practical applications of small and medium-sized conference rooms, the efficient operation of the conference system relies on the coordinated action of multiple functional modules. First, when a user speaks, the sound signal enters the pickup assembly through the guide holes 3 on the pickup cavity 2. The spiral arrangement and guide slope design of the guide holes 3 effectively reduce external wind noise interference, while the sound-absorbing coating of the buffer cavity further absorbs residual noise, thereby improving the pickup quality. The sound signal collected by the pickup is then transmitted to the filtering unit 6 in the signal processing module after being filtered by both the elastic support and the sound-absorbing material. The filtering unit 6 ensures the accuracy of subsequent voice command parsing by removing high-frequency and low-frequency interference signals.
[0038] Subsequently, the instruction parsing unit 7 identifies the user's control command based on the data stored in the voice feature parameter library and transmits the parsing result to the encryption unit 8. The encryption unit 8 sends the encrypted command to the transmission module via the RF connector. At this time, the UHF antenna or 5G Wi-Fi module selects the appropriate communication method according to the actual environment and transmits the command to the linkage interface unit. For example, in a scenario where the video signal source of the conference room display device is switched, the power controller 10 starts the video switcher 11 after receiving the command. The video switcher 11 transmits the specified video signal to the display device via the HDMI cable, completing the signal source switching.
[0039] Meanwhile, the design of adjustment knob 5 allows users to adjust the size of the airflow channel within the pickup cavity 2 according to specific needs. By rotating adjustment knob 5, the position of the damping plate changes, and the airflow channel between the arc-shaped slot and the inner wall of the adjustment cavity also changes accordingly, thus affecting the acoustic feedback effect. This flexible adjustment mechanism enables the system to adapt to the acoustic environment of different conference rooms, improving the stability of the sound pickup effect.
[0040] The combination of touch button 14 and voice control further enhances the system's reliability. When a user presses touch button 14, the pressure sensor detects the pressure applied and transmits the signal to the signal processing module. The honeycomb arrangement of the raised dot matrix 15 not only improves the tactile feel of touch button 14 but also prevents accidental touches. LED indicator strip 16 is connected to the surface of touch button 14 via a light guide strip, providing real-time feedback on the operating status and ensuring that users can intuitively understand the device's working condition.
[0041] Furthermore, the adaptive calibration unit 9 automatically optimizes the pickup parameters by accessing data from an environmental noise parameter library. For example, in a noisy conference room, the adaptive calibration unit 9 adjusts the microphone sensitivity to ensure accurate recognition of voice commands. The status monitoring module continuously monitors the operating status of external devices. Once an anomaly is detected, it immediately generates a fault warning signal and notifies the signal processing module via a wireless communication protocol, allowing for timely countermeasures.
[0042] The above process demonstrates the specific application scenario of this utility model in small and medium-sized conference rooms. Through the coordinated work of the pickup component, signal processing module, transmission module, and linkage interface unit, the efficient operation of the central control-free wireless conference microphone system is achieved. The design of the pickup cavity 2 and the anti-interference cover 4, combined with the multiple noise reduction effects of the airflow hole 3, significantly reduces interference from external wind noise and environmental noise; the coordinated design of the adjustment knob 5 and the pickup cavity 2 provides flexible acoustic feedback adjustment capabilities; the dual confirmation mechanism of the touch button 14 and voice control, combined with the design of the pressure sensor and raised dot matrix 15, ensures both ease of operation and avoids accidental operation; the real-time monitoring function of the status monitoring module ensures the stability and reliability of the entire system.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
