The invention discloses a novel voice and ultrasonic integrated bird dispelling system which comprises a power source, a data processing device, a photoelectric detecting device, an ultrasonic transmitting device and a voice frequency transmitting device. Whether birds approach the novel voice and ultrasonic integrated bird dispelling system or not can be detected by the photoelectric detecting device, electric signals can be transmitted to the data processing device when approaching of the birds is detected, signals are transmitted and outputted to the ultrasonic transmitting device and the voice frequency transmitting device by the data processing device after the electric signals are received, and accordingly the ultrasonic transmitting device and the voice frequency transmitting device can be started to dispel the birds. The novel voice and ultrasonic integrated bird dispelling system has the advantages that the birds can be dispelled without being harmed, and accordingly the novel voice and ultrasonic integrated bird dispelling system is favorable for protecting ecological environments.
