Accompanying drawing 9 is electrical schematic diagrams that the utility model has increased the amusement trigger circuit

Accompanying drawing 10 is electrical schematic diagrams that the utility model has increased the urine-wet alarm switch

As shown in Figure 1, the utility model comprises the wet detection circuit 2 of urine, control circuit 4 (IC1004), pronunciation circuit 6, illuminating circuit 5, power supply E and shell etc., it increases by the detection circuit 1 of crying and screaming on this circuit base, be in series by R1, Electret condenser microphone MIC and R2.R2 can adopt adjustable resistance, and as shown in Figure 2, this is adjustable sensitivity channel; If the R2 fixed resistance then is non-adjustable sensitivity channel.

Under the normal condition, the two ends making alive of the detection circuit of crying and screaming of care device, string body dividing potential drop is E1, E2, when giving great volume＜infant cries and screams 〉, dividing potential drop is E1 ', E2 ', gets final product trigger control circuit when E2 ' exceeds the control circuit trigger value, control circuit sends pulse train and gives the triggering pin, signal is pacified in control circuit output, after amplifying, exports to the infant to pacify by pronunciation, illuminating circuit.Control circuit can adopt ic chip 1004, ICM1220, ICMS-01 etc.

As shown in Figure 3, visit the sound element and change carbon powder microphone MIC into by Electret condenser microphone MIC.

As shown in Figure 4, serve as the detection circuit of crying and screaming of visiting the sound element with carbon powder microphone MIC, its R2 is an adjustable resistance.

As shown in Figure 5, the detection circuit of crying and screaming can be made up of R1, Electret condenser microphone MIC, capacitor C, transistor T and R2, and under the normal condition, the R1 terminal voltage is constant, and the capacitor C no current passes through; When the infant cries and screams, the R1 voltage undulation, AC signal is coupled to the b end of transistor T by capacitor C; Micro-signal amplifies through transistor T, Drive and Control Circuit, and signal is pacified in control circuit output, delivers to pronunciation, illuminating circuit through amplification.
