Technical Field

[0001] The present invention relates to the field of conference venue acoustics, and in particular to a conference venue acoustics environment detection device. Background Art

[0002] In the field of venue acoustic environment detection, traditional detection devices have many limitations. On the one hand, the installation and adjustment of the detection device are often cumbersome, requiring a lot of time and manpower for debugging, and it is difficult to quickly adapt to the layout and needs of different venues. On the other hand, the detection device lacks flexibility, making it difficult to achieve precise adjustment in multiple dimensions, and cannot meet the comprehensive coverage of sound detection at different locations in the venue. In addition, the stability of the detection device and the ease of operation need to be improved to ensure stable operation and acquisition of accurate acoustic environment data in complex environments. In order to overcome these shortcomings, it is particularly important to develop a venue acoustic environment detection device with a reasonable structure, convenient adjustment, and strong stability.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the cooperation between the first rotating shaft and the rotating wheel allows the detection device body to move around the shape of the mounting frame to adapt to changes in the shape of the venue. At the same time, the design of the second rotating shaft and the turntable allows the detection device body to be adjusted in angle, facilitating alignment with a specific detection area. In addition, the combined structure of the threaded rod, nut, and sleeve enables height adjustment of the detection device body, further enhancing the adaptability and flexibility of the device. This multi-dimensional adjustment function ensures precise positioning and all-round detection of the detection device in the venue, thereby improving the coverage and accuracy of detection.

[0015] 2. In the present invention, by pulling the pull block, the fixed slide rod and the fixed slide groove can be easily separated or fixed, thereby conveniently adjusting the angle of the detection device body, and the setting of the spring can ensure that the fixed slide rod is automatically reset and fixed after the pull block is released, making the adjustment process more labor-saving. When adjusting the height, it is only necessary to turn the nut and hold the connecting frame to achieve the up and down movement of the detection device body, without the need for complex tools or tedious operating steps. At the same time, the device has a compact structure and the connection between the various components is firm, which can effectively resist vibration and interference during the detection process, ensure the stability of the detection device during operation, and ensure the reliability and consistency of the detection data;

[0016] 3. In the present invention, the first rotating shaft and rotating wheel are driven by a drive motor to achieve automatic movement of the detection device body, thereby improving detection efficiency. Compared with manual adjustment, the automated movement method not only saves manpower but also allows detection according to a preset trajectory and speed, making the detection process more uniform and comprehensive, and avoiding omissions or duplications caused by human factors. In addition, the device's combined height adjustment and angle adjustment functions can be quickly adjusted to the optimal position according to detection requirements, shortening the preparation time before detection and further improving overall detection efficiency.
