In addition, the ultrasonic bird repellent device has stable operation and is easy to install.

[0036] Furthermore, the ultrasonic generator 33 can be an ultrasonic directional speaker, that is, the ultrasonic directional speaker can emit ultrasonic waves in a specified direction, and can accurately transmit ultrasonic waves to a specific area, avoiding interference with the surrounding environment, and improving the utilization efficiency of ultrasonic waves. The sound wave intensity is greater, and the effect of repelling birds is better.

[0037] Optionally, the ultrasonic wave band of the ultrasonic generator 33 is 13-25kHz, which can have a strong repelling effect on birds without causing much interference to humans and other animals.
