Abstract

The utility model provides a sound controlling weak light music door bell. The sound controlling weak light music door bell is composed of a plastic outer shell and a circuit part, wherein, the circuit part is composed of an input stage I, a sensitivity controlling circuit II, an intermediate stage III and a music and light output stage VI. The circuit can convert the door knocking sound of one time to the electric signal to control the door bell and a weak light door lamp for illuminating a keyhole. The door bell uses the same circuit to simultaneously control the door bell and the weak light door lamp (2). The sound controlling weak light music door bell has the advantages of adjustable sensitivity, no lamp controlling part, low power consumption, easy starting method, guest door knocking sound distinction, low cost, etc.

Description

Sound-control microlight music door bell

The utility model relates to a kind of acoustic control low-light electronic music doorbell.

Existing doorbell, gate light all are single function self-organizing systems, promptly have two cover circuit to control doorbell and gate light respectively respectively, and this has not only improved the price of product, and makes troubles for installation and use, and promptly doorbell and gate light all will use separately.In addition, thereby have a kind of doorbell twice sound that knocks at the door can be converted to signal of telecommunication control doorbell in the prior art, but its sensitivity can not be adjusted.

The purpose of this invention is to provide a kind of acoustic control low-light music door-bell that doorbell and gate light are combined as a whole, promptly control doorbell and gate light simultaneously with same circuit, this circuit can convert the sound that once knocks at the door to signal of telecommunication control doorbell and be used for the low-light gate light of keyhole illumination.This doorbell also has the characteristics that the difference guest knocks at the door except that having the adjustable characteristics of sensitivity.

Narrate technical solution of the present utility model below in conjunction with accompanying drawing.

The doorbell that the utility model relates to is made up of plastic casing (1) and circuit part two large divisions.Circuit part (as Fig. 1) comprises input stage I, sensitivity adjustment circuit II, intergrade III and sound light output stage IV, circuit is formed components and parts to be had: resistance R 1, R2, potentiometer W, high frequency low-power transistor T1, T2, T3, capacitor C, integrated IC, loud speaker YD, low-light gate light (2), toggle switch (3), vibrating sensor Pi and power supply Ec(5 battery two joints).Between wherein at different levels and the annexation of each device as follows, the loud speaker YD of output stage IV links to each other with a hybrid circuit with T3 by triode T2 respectively with low-light gate light (2), this circuit is distinguished control loudspeaker YD and low-light gate light (2) simultaneously, and it includes input stage I, sensitivity adjustment circuit II and intergrade III.Integrated IC of intergrade III is made up of circuits for triggering, oscillating circuit and delay circuit, its each pin is the h-trigger electrode, the i-output stage, the j-supply pin, the k-grounding leg, above-mentioned i pin links to each other with the base stage of triode T2 and T3, the h pin connects the potentiometer W cursor slide of sensitivity adjustment circuit II, the two ends in addition of potentiometer W link to each other with the jk end of integrated IC, and local sensitivity can be adjusted by potentiometer W, thereby reaches the purpose that the difference guest knocks at the door.Emission-collector electrode of the triode T1 of input stage I and a collector resistance R2 link to each other with the Kj end of integrated IC, the collector electrode of triode T1 links to each other with potentiometer W cursor slide by a capacitor C, the base-emitter of triode T1 vibrating sensor pi in parallel, the sound that once knocks at the door can be converted to the signal of telecommunication, amplify the trigger electrode h pin that is added in integrated IC through capacitor C by triode T1, triggering through the intergrade III, vibration and time-delay, distinguish control loudspeaker YD and low-light gate light (2) through the amplification of triode T2 and T3 again, the delay circuit control doorbell melody time of integrated IC, when it finishes, oscillating circuit is ended, thereby finish the melody sound and stop the low-light illumination, the base stage of triode T1 links to each other with the j end of integrated IC by a resistance R 1.Integrated IC is music integrated circuit, and the employing serial model No. is CW9300, SVM79, HY-100, HY-101 or NS118.

After the circuit board of circuit part was packed in the plastic casing (1), toggle switch (3) was located at the side of plastic casing (1), and low-light gate light (2) is contained in above door (5) outer built-in lock (4) nearby.

Below with regard to Fig. 3 the operating position of this machine is described.Toggle switch (3) is a mains switch, when (3) put " pass ", deenergization, being used for house-owner people does not need the occasion of doorbell and gate light, when (3) put " opening ", it is static that this machine is in energising, and static power consumption is less than 5 microamperes, in a single day have the people to knock at the door this moment, can send the music door-bell sound and shine keyhole with the low-light gate light.This motor-driven attitude power consumption is not more than 150 milliamperes, and the dynamic delay of the triggering work that once knocks at the door is in 15 seconds.

These facility have sensitivity to adjust on a large scale, and low in energy consumption, Starting mode is easy, and the difference guest knocks at the door, and saves lamp controller spare, low cost and other advantages.
