Description

Technical Field

[0001] This utility model relates to the field of sound wave bird deterrence technology, and in particular to a modular omnidirectional sound wave control box. Background Technology

[0002] Bird strikes are a common problem in the aviation industry. Statistics show that over 80% of bird strikes occur during takeoff, landing, and low-altitude / ultra-low-altitude flight. Therefore, installing bird deterrents within airport areas is one of the effective ways to prevent bird strikes. Currently, most airport flight zones use physical bird deterrence methods, employing acoustic bird deterrent devices, but the results are not ideal. Acoustic bird deterrent devices use sound waves that are highly directional, decay rapidly, and cannot penetrate obstructions. Patent application number 202320988007.3 discloses a 360-degree omnidirectional acoustic bird deterrent device. In this device, a 2U control box is installed at the lower end of a butterfly-shaped acoustic deflector. The overall structure is relatively large, and the control box only generates bird deterrent audio signals, making its function limited. Operators cannot select the playback of the bird deterrent audio or know the playback time. Therefore, this control box requires further optimization and improvement. Utility Model Content

[0019] Please refer to the appendix. Figure 1 , 2 This embodiment provides a modular omnidirectional acoustic wave control box, which is connected to an omnidirectional acoustic wave diffuser. The control box includes a box body 1 with an openable and closable top cover 11. The top cover 11 is equipped with a display screen 2 and a power switch 3. Inside the box body 1, there is a power amplifier 4, a control board 5, and a power module 6. The control board 5 is located on the lower surface of the top cover 11. Multiple sets of power amplifiers 4 are provided and located below the control board 5. The power module 6 is fixed to the bottom of the box body 1 and is on the same side as the power amplifiers 4. The power module 6 is connected to the power switch 3 and is used to control the opening and closing of the power switch 3. The power module 6 is used to supply power to the display screen 2, the power amplifiers 4, and the control board 5. It also includes cable routing holes 7. Cable routing holes 7 are provided on the front and rear side walls of the box body 1. The power module 6 is connected to an external power source through the cable routing holes 7, and the power amplifier 4 is connected to a speaker through the cable routing holes 7.
