Disclosed is a sound signal generator for a traffic signal lamp. The present invention comprises a voltage control unit which blocks a fuse due to an overcurrent in a status where an AC voltage of a traffic signal lamp controller is supplied to a power supply unit to be rectified and to be supplied to the sound signal generator, and lowers the voltage when the voltage on both ends is increased. Accordingly, when a defective current flows into the power supply unit, which supplies power to the sound signal generator which operates by being connected to the traffic signal lamp controller, and the fuse is blocked, the present invention prevents an error such as a simultaneous turning on of the green light and the red light on the traffic signal lamp for vehicles or pedestrians, which are controlled by the traffic signal lamp controller, by blocking the operation in connection between the sound signal generator and the traffic signal lamp controller.

    본 발명은 신호등용 음향신호기를 개시한 것으로, 이러한 본 발명은 신호등 제어기의 교류전압이 전원공급부에 공급된 후 정류되고 정류된 전압이 음향신호기에 공급되는 상태에서 과전류로 인해 퓨즈의 차단동작하여 그 양단전압이 높아질 때 이를 전압강하시키는 전압제어부를 구성한 것이며, 이에따라 신호등 제어기와 연계 동작하는 음향신호기로 전원을 공급하게 되는 전원공급부에 이상전류가 흘러 퓨즈의 차단동작이 이루어질 때, 음향신호기와 신호등 제어기의 연계 동작을 차단하면서 신호등 제어기에 의해 제어되는 차량용 또는 보행자용 신호등의 녹색 및 적색이 동시에 점등되는 등의 오류를 방지하도록 한 것이다.
