Story machine with sound induction alarm function

Abstract

The invention discloses a story machine with a sound induction alarm function. The story machine comprises a story machine body and a monitor. The story machine body comprises a voice circuit, a sound sensing circuit, a triggering circuit, a low-frequency oscillation circuit, a 49.86MHz oscillation circuit and a modulation transmission circuit, wherein the output end of the sound sensing circuit is connected with the input end of the triggering circuit; the output end of the triggering circuit is connected with the input end of the low-frequency oscillation circuit; the output end of the low-frequency oscillation circuit is connected with the input end of the 49.86MHz oscillation circuit; and the output end of the 49.86MHz oscillation circuit is connected with the modulation transmission circuit. The monitor comprises a receiving demodulation circuit and a low-frequency amplifying circuit, wherein the output end of the receiving demodulation circuit is connected with the input end of the low-frequency amplifying circuit. When an infant cries, the story machine body senses the voice of the infant and transmits wireless electric waves, and the monitor receives the wireless electric waves and sends out a prompt signal, so a guardian can know the abnormal status of the infant timely.
