Accompanying drawing explanation

Fig. 1 is the circuit diagram gradually ringing formula sleep awakening device.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this 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 this utility model protection.

Refer to Fig. 1, in this utility model embodiment, one gradually rings formula sleep awakening device, comprises chip U1, chip U2, electric capacity C1, set of cells E, buzzer B, diode D1 and resistance R1, set of cells E positive pole connect electronic clock timing contact K, set of cells E negative pole contact resistance R1 respectively, chip U1 pin 1, resistance R3, electric capacity C2, chip U2 pin 1 and resistance R6 ground connection, the electronic clock timing contact K other end connects electric capacity C1 respectively, chip U1 pin 4, chip U1 pin 8, resistance R2 and audion VT1 colelctor electrode, the electric capacity C1 other end is the contact resistance R1 other end respectively, chip U1 pin 2 and chip U1 pin 6, chip U1 pin 3 connect diode D1 positive pole, and diode D1 negative pole is the contact resistance R2 other end respectively, the resistance R3 other end and audion VT1 base stage, audion VT1 emitter stage is contact resistance R4 respectively, chip U2 pin 4, chip U2 pin 8, diode D2 positive pole and electric capacity C4, the electric capacity C4 other end connects diode D2 negative pole and ground connection, and the resistance R4 other end respectively contact resistance R5 and chip U2 pin 7, the resistance R5 other end connects the electric capacity C2 other end respectively, chip U2 pin 2 and chip U2 pin 6, chip U2 pin 3 connect electric capacity C3, and the electric capacity C3 other end connects buzzer B, the buzzer B other end contact resistance R6 other end.

Chip U1 and chip U2 model are NE555.

Set of cells E voltage is 9V.

Operation principle of the present utility model is: refer to Fig. 1, chip U1, resistance R1 and electric capacity C1 forms a delay switch circuit, chip U2, resistance R4, it is the multivibrator of 800HZ that resistance R5 and electric capacity C2 forms a frequency, when the set of cells E of circuit connects by electronic clock timing contact K, because the voltage on electric capacity C1 can not suddenly change, chip U1 pin 2 is high level, now, the outfan pin 3 of chip U1 is in low level, diode D1 ends, because the junction voltage pressure drop of audion VT1 is large, the power electric adding to chip U2 is forced down, the sound that chip U2 control buzzer B sends is more weak, along with set of cells E is to the charging of electric capacity C1, when the pin 2 of chip U1 and the current potential of pin 6 drop to 1/3 threshold level, circuit overturns, chip U1 pin 3 becomes high level, this charging delay period is about 8S, afterwards, due to diode D1 conducting, the base potential of audion VT1 uprises, audion VT1 junction voltage becomes very little because of saturated, thus the voltage of chip U2 is added to close to 9V, control buzzer B and send fierce sound.
