Description

Sound controlled on/off electronic switch

The utility model relates to the switch that a kind of illuminating lamp is used.

Existing general switch, generally only have illuminating lamp is played the effect that is switched on or switched off power supply in use, as pulling switch, button switch etc., and the acoustic control delay switch that occurs, Multi-functional Lighting switch or the like, it all is function singleness, only have the effect of time-delay,, also be not subjected to liking of people so lost its versatility.The user tends to the difference according to the field of employment, switch has been proposed various requirement, as open or close by acoustic control, time-delay etc., existing switch does not then also possess these functions, so be necessary fully to develop and a kind ofly can come the electronic switch of open and close, time-delay by acoustic control, with get married different needs.

The purpose of this utility model is for providing a kind of clapping the hands that the bright or lamp of lamp is gone out, acoustic control open and close, the delay electronic switch that can delay time again, and this switch install, very easy to use.

Technical solution of the present utility model is: utilize the mechanical oscillation of sound wave, convert voice signal to the signal of telecommunication through piezoelectric ceramic piece, carry out work through amplifying the circuit that starts the back again, and utilize the cmos circuit principle of not power consumption in theory, when forming bistable state, zero load and the difference that loads on the electric current variation utilize power supply and integration to carry out timing, come open and close or delayed lamp and reach by acoustic control.

Accompanying drawing has been described an embodiment of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.The acoustic control open and close, the delay electronic switch that are proposed, it is to be a square box body for a profile, and is made up of face-piece (1), switch key (6), circuit board (10), one-way SCR (11), diode (12), electric capacity (13), resistance (14), integrated package (15), light-emitting diode (16), socket (17) and piezoelectric ceramic piece (18) etc.Its circuit board (10) is that design and installation is in drain pan (9), at its one-way SCR (11), D ₁To D ₉Diode (12), C ₁To C ₈Electric capacity (13), R ₁To R ₁₄Resistance (14) and IC integrated package (15) they are that distribution design is positioned on the circuit board (10), and in switch button (6), light-emitting diode (16), socket (17) and piezoelectric ceramic piece (18) to be distribution design the be positioned on face-piece (1).

As shown in Figure 1, the design of face-piece described in the utility model (1) upper left corner has a lightening hole (2), lower right corner design has a sound transmission aperture (8), middle design has one by buttonhole (5), designed a jack (7) again by the below of buttonhole (5), and the position that light-emitting diode (16), switch key (6), socket (17) and piezoelectric ceramic piece (18) are installed is corresponding with each hole in face-piece (1).

Operation principle of the present utility model and using method: now 1,2,3 its principle, D are described with reference to the accompanying drawings ₁-D ₅Rectifier diode, D ₆-D ₈Switching diode, D ₉Voltage stabilizing didoe, C ₁Input coupling capacitor, C ₂Inter-stage coupling capacitor, C ₃Integrating capacitor, C ₄Anti-interference capacitor, C ₅, C ₆Coupling capacitor, C ₇Timing capacitor, C ₈Filter capacitor, R ₁, R ₂Biasing resistor, R ₃Anti-interference resistance, R ₄-R ₇Bistable state biasing resistor, R ₈, R ₉Discharge resistance, R ₁₀-R ₁₂Adjust biasing resistor, R ₁₃, R ₁₄Dropping resistor.Door ₁With outer meeting resistance R ₁Be connected into one-level amplifier door ₂With outer meeting resistance R ₂Be connected into second level amplifier, R ₁₂Be used for adjusting door ₂The DC potential of output obtains needed sensitivity, door ₃Isolate and the shaping pulse effect door with playing inter-stage ₄With D ₆, R ₉C ₃Form pseudo-monostable circuit, door ₅, the door ₆C with the periphery ₅, C ₆, R ₄, R ₅, R ₆, R ₇, D ₇, D ₈Form bistable circuit, BCR and D ₁～D ₄Form the gate-controlled switch circuit.When clapping the hands, the sound signal of bursting converts the signal of telecommunication to through piezoelectric ceramic piece, and the signal of telecommunication amplifies the back through two-stage and starts pseudo-monostable circuit, door ₃Just export pulse train, D is passed through in this pulse ₆To C ₃Charging is at C ₃Set up a voltage, this voltage makes door ₄Become low level from high level, C is crossed in pulse ₃Pass through R ₉Discharge, C ₃On voltage drop to a certain value, the door ₄Revert to high level again, so whenever hit the supremo one time ₄Just export a negative pulse, this negative pulse triggers bistable circuit, utilizes the upset of bistable circuit to come the control switch circuit and realize that acoustic control opens or closes.Time-delay regularly is to utilize the power supply integration, and carries out regularly.Connect C during the time-delay timing ₇, disconnect R ₃, utilize the static characteristics different of control circuit, C when static with the dynamic duty electric current ₃On be full of electricity, operating current increases after circuit triggers, C ₇Just to load discharge, along with discharge C ₇Last current potential is more and more lower, when current potential is lower than a certain value, and the circuit cisco unity malfunction, the gate-controlled switch circuit automatically shuts down, thereby realizes regularly.So connect with the mains or load, when not working, load can from lightening hole, see red light-emitting diode, switch was in and opened or closed the position this moment.Hit and once slap loaded work piece, lamp is bright, hits and once slaps the load disconnection, and lamp puts out.When switch key was got to another position, light-emitting diode (indicator light) did not work, and promptly hits and once slaps loaded work piece, automatically shut down after a period of time, and time-delay is generally in two minutes.

The utility model is owing to adopted above-mentioned technical solution, and it compared with prior art has following advantage:

1. working stability is reliable, and is extremely strong to the antijamming capability that power supply disturbs, and only to bursting property sound sensitive, the sound such as its talk, TV, sound equipment do not have impact to it yet to sound.

2. of many uses, can make road lamp switch and use, can be used for the switch of indoor lamp again, can be used for the electric power starting of household electrical appliance such as television set, recorder, electric fan simultaneously and close.

3. because of control section is to be operated under low-voltage, the little current conditions, thus the switch long service life, and switch is low in energy consumption, and cost is also low, and result of use is very good.
