Description of drawings
1. accompanying drawing is the circuit working schematic diagram of induction type electronic doorbell.
2. the IC1 in the accompanying drawing is KD9300 or CW9300 type music integrated circuit.
Embodiment
Technical requirement according to the components and parts of induction type electronic doorbell fundamental diagram shown in the drawings and description of drawings and the following stated is implemented, and can realize the utility model.
The selection of components and parts and technical parameter thereof
1.VT1～VT4 selects 2CS9013 or 2CS8050 type NPN silicon transistor, enlargement factor β 〉=150 for use;
2.IC1 select KD9300 or CW9300 type music integrated circuit for use, packing forms is soft encapsulation.The pin that the rectangular indentation both sides are arranged in the soft encapsulation is 7 pin, 8 pin, and the large tracts of land Copper Foil is circuit ground (GND), and the pin that is printed on VDD or VCC printed words connects the positive pole of direct supply, is printed on IN, the OUT printed words are respective pins;
