Abstract
The utility model relates to an incoming call warner, comprising a power supply. The incoming call warner is characterized in that the warner also comprises an incoming call detection circuit, a microcontroller, an incoming call indicator light and a tweeter. The input end of the incoming call detection circuit is connected with a phone line, and the output end is connected with the incoming end of the power supply. When a phone is called, a ringing signal is generated; the incoming call detection circuit detects the ringing and transmits a low level signal to the microcontroller. The microcontroller controls the blink of the indicator light and the chirping of the tweeter according to the signal transmitted from the incoming call detection circuit. When the phone is answered, the incoming call detection circuit can not detect the ringing signal, and transmits a high level signal. The microcontroller stops the blink of the indicator light and the chirping of the tweeter according to the signal transmitted from the incoming call detection circuit. The incoming call warner has high warning sound and good blink effect, and can warn an incoming call effectively.
