Description of the drawings
Fig. 1 is the circuit diagram of time delay sound light music doorbell of the present invention.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, the circuit of the time delay sound light music doorbell of the present invention using 220V civil power Jing transformator T1 blood pressure lowerings, two
After level pipe D1～D4 bridge rectifiers, electric capacity C1 filtering, direct current 9V power ends and ground is formed respectively in the positive and negative end of electric capacity C1
The control circuit to rear class and acousto-optic circuit is held to be powered.
The control circuit is built using time base circuit NE555 chips, one end of 9V power supply connecting resistance R1, resistance R1
Another termination NE555 chip 2 feet and one end of knob K, knob K the other end ground connection；4,8 feet of NE555 chips meet 9V
Power supply, 6,7 feet connect one end and adjustable side of adjustable resistance RP and the positive pole of electric capacity C2, another termination 9V electricity of adjustable resistance RP
Source, the minus earth of electric capacity C2；The 1 foot ground connection of NE555 chips, is grounded after 5 foot serial capacitance C3, and 3 feet are exported to acousto-optic circuit.
The acousto-optic circuit is built using music flashing integrated circuit HFC1531 modules, a termination control of resistance R2
3 feet of circuit NE555 chips processed, the VDD feet and TRIG feet and Zener diode of another termination HFC1531 module of resistance R2
The negative pole of DZ, the plus earth of Zener diode DZ are connected with light-emitting diodes between the VDD feet and LED1 feet of HFC1531 modules
