Accompanying drawing explanation
Fig. 1 is the circuit diagram of entryphone circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of entryphone circuit, comprise rectifier bridge T, resistance R2, chip IC 1 and electric capacity C1, one end of described electric capacity C1 connects button K and outside line A, the other end contact resistance R1 of electric capacity C1 and the other end of button K, the other end of resistance R1 connects the port one of rectifier bridge T, the port 3 of rectifier bridge T connects outside line B, the port 2 of rectifier bridge T connects the negative electrode of diode D1, electric capacity C2, the pin 1 of resistance R2 and chip IC 1, the other end of resistance R2 connects the pin 2 of chip IC 1, the pin 3 contact resistance R3 of chip IC 1 and electric capacity C3, the other end of resistance R3 connects the pin 4 of chip IC 1, the other end of electric capacity C2 connects the other end of electric capacity C3, the anode of diode D1, electric capacity C5, the pin 5 of chip IC 1, the port 4 of rectifier bridge T and loudspeaker B, the pin 8 of chip IC 1 connects electric capacity C4, the other end contact resistance R5 of electric capacity C4, the other end of resistance R5 connects the other end of loudspeaker B, the pin 7 contact resistance R4 of chip IC 1 and the other end of electric capacity C5, the other end of the pin 6 contact resistance R4 of chip IC 1, the model of described chip IC 1 is CS8204.
Diode D1 is voltage stabilizing didoe.
Operation principle of the present utility model is: circuit comprise give orders or instructions, receive words, to send out number, ring four part, wherein ringing circuit adopts C58204 type special ring integrated circuit die I C1.When outside line has phone to throw into, telephone exchange is just from the ringing signal of outside line A and B defeated people 90V, 25Hz, through C1, R1 current limliting, rectifier bridge T bridge rectifier, voltage stabilizing didoe D1 voltage stabilizing and electric capacity C2 filtering, a galvanic current pressure just adds between 1,5 pin of chip IC 1, chip IC 1 enters people's operating state, bell signal exports from 8 pin, sends the phone ringing sound by loud speaker.48V direct voltage is had due on outside line at ordinary times, C1 has stopping direct current to lead to the effect of interchange, circuit bell not sound during C1 open circuit, during C1 short circuit, telephone ringer is long rings, therefore button K in parallel on C1, during use, as long as click button K, C1 is just shorted, and namely direct voltage is added on voltage-stabiliser tube D1 after R1, rectifier bridge T, just have operating voltage between 1,5 pin of chip IC 1, telephone ringer has just rung.If phone occurs ringing tone when normal talking, illustrate that guest is pressing bell button.Circuit structure is simple, components and parts are few, using the special ring integrated circuit of C58204 type as circuit core, doorbell and phone is combined, and only need press doorbell button will trigger telephone rings, and easy to use, cost of manufacture is low, has certain market space.
