CN2085992U - Integrated electronic door bell - Google Patents

Abstract

The integrated electronic doorbell is a door sensor which takes the vibration sound of tapping two lower doors as a sensor; thereby enabling the music integrated blocks of various sounds to produce sound. The structure of the utility model is integrated; the product can be directly hung behind a door after being bought or can be used after being adhered to the door by self adhesive sticker. The trouble of punching and installing an outdoor button of the existing doorbell and the inconvenience of finding the button during use are avoided. In addition, if necessary, the indoor and outdoor road lamps can be automatically lightened by remote control; and can also play a role of alarming when a thief prizes the door.

Description

Integrated electronic door bell

The utility model is a kind of integrated electric doorbell, belongs to electronic technology field.

The early stage doorbell that uses drives mechanical motion by solenoid and knocks and sting the When sounding, along with development of electronic technology, the present electronic door bell that uses comparatively general doorbell then to form by music-integrating block, the both need install PBU pushbutton unit out of doors for messenger's use of signaling, and being placed with audible segment indoors, in fact a whole set of doorbell is made up of above-mentioned two parts.The threading that must punch on door when mounted connects doorbell and button, and comparatively trouble is installed, and button is installed is not in addition had unified regulation, often makes the night visitor can't find button position.

Goal of the invention of the present utility model is to have designed a kind of usefulness and rapped the integrated electric doorbell that the chatter of door replaces button at the deficiency of prior art existence.

The utility model is that following manner is finished: add shell by vibration transducer, amplifier, many counters of transient state, music-integrating block, loudspeaker and battery and form, package unit is integrated in one, directly hang over or be bonded at behind the door and can use, the visitor only need rap several Xiamen, then this doorbell continues for some time at once sends loud euphony, installs and uses very convenient.

Principle of work of the present utility model and one-piece construction are passed through description of drawings.

Accompanying drawing is a fundamental diagram of the present utility model.

Sensor presses HTD to form by pottery, is connected to common emitting stage transistor T₁Input, T₁The output colelctor electrode CP that receives simultaneously two d type flip flops of double D trigger 4013 hold 11 pin and 3 pin, input 9 pin of first order d type flip flop connect positive supply, export 13 pin and pass through R₂C ₃Be connected to second level d type flip flop after the time-delay and import 5 pin, the second level is exported 1 pin and is linked to each other with the control end of music-integrating block MIC, and the output 13 and 1 of two-stage d type flip flop respectively is connected to R₁And R₃The R that resets that is connected to self holds 10 pin and 4 pin, respectively passes through then capacitor C₁And C₃Ground connection (negative supply).

The course of work is as follows: HTD receive first sound knock at the door the vibration after; The signal of telecommunication of changing out Make preposition amplifier tube T₁Conducting is at R₄Two ends obtain direct impulse, and the CP of two d type flip flops holds 11 pin and 3 pin to receive simultaneously triggering level, because second level trigger is imported 5 pin and passed through capacitor C₂Ground connection is low level so second level trigger is exported 1 pin, and music MIC does not work, and loudspeaker Y is noiseless. Because it is high level that first order d type flip flop is imported 9 pin, it is high level that the first order is exported 13 pin simultaneously, and the high level of its output passes through R₂，R ₃Give respectively C₂、C ₃Charging, C₂Rise to high potential after about 0.5 second, so if sustained vibration and other back drop are arranged before this, all because C₂Electronegative potential second level d type flip flop can not overturn. C₃Therefore be charged to high potential after about 3 seconds, strike second Xiamen in 0.5 second～3 second time after the first sound vibration again, then because second level d type flip flop is imported 5 pin and has been charged to high potential, and make second level d type flip flop upset, MIC promotes the loudspeaker Y sounding. The second level is exported 1 pin and is passed through R subsequently₂Give C₁Charging made second level d type flip flop reset terminal 4 pin become high level and forced resetting, C after about 3 seconds in about 0.5 second₃Also be charged to current potential, force first order trigger reset. Get back to original state, wait for lower task. So circulation has just realized replacing with two acoustic vibrations at interval the function of button, and the scope of two blanking times is set can be by adjusting R₂And R₃Realize because chatter blanking time scope effective, the misoperation that can avoid closing the door remained shock and other external interference cause. Can adopt 3D or 4D trigger to consist of 3 or four tones of standard Chinese pronunciation transient state counter in order further to improve reliability.

Further specifying this integrated electric doorbell with an embodiment, HTD is-piezoelectric ceramic piece of 27 millimeters of φ, double D trigger is 4013, and MIC adopts the KD-153 of " ding-dong " sound, and loudspeaker adopted 1 o'clock, 8 Ω's, R ₁=R ₂Be 470K Ω C ₁=C ₂With 1 μ F, R ₃Be 1M Ω, C ₃Be 3.3 μ F, R ₄Be 24K Ω, R ₅Be 390K Ω, R ₆Be 2M Ω.Power supply saves No. 5 batteries with two.According to the integrated electric doorbell of accompanying drawing assembling, as long as rap door twice, and first with second sound interval time in 0.4 second～2.5 seconds scopes, can hear melodious " ding-dong " sound three, about 0.02 milliampere of quiescent current.
