The circuit of the snoring and sleep talking therapy device can effectively prevent snoring or sleep talking during sleep. After using it for a period of time, it will form a conditioned reflex and gradually get rid of these problems. As soon as the snorer snores or the sleep talker talks in his sleep, the circuit emits acupuncture-like electric anesthesia pulses to wake him up and stop snoring or sleep talk. working principle
After the microphone MIC picks up snoring or words, it is coupled to the composite amplifier composed of VT1 and VT2 via C for amplification. After the signal voltage is boosted by T, it is controlled by RP for output. See Figure 1 for component selection and manufacturing component selection. The microphone MIC uses an ordinary electret condenser microphone, and the T is wound with the iron core of a portable radio output transformer. The primary is wound with 80 turns of Φ0.15mm enameled wire, and the secondary is wound with 5000 turns of Φ0.08mm enameled wire. RP is a 47k potentiometer with switch. The power supply uses two AA batteries. The electrode is welded to two thin insulated wires with a copper sheet about 0.5-1mm thick, and the copper sheet is bent into a ring and put on two non-adjacent fingers. When using it, first learn the snoring sound with a distance of 30-5cm from the microphone, adjust the RP so that the degree of electric anesthesia between the two fingers is appropriate, and then it can be put into use.
