CN2909413Y - Multifunction alarm megaphone for help - Google Patents

Abstract

A multiple functional megaphone for alarm and recourse includes a power, a sensor and an acoustic generator. The three parts are series-wound, wherein the acoustic generator is a megaphone with a recording function, the sensor is a switch sensor. The utility has universal functions, and it has a rich content for anti-theft alarm, the alarm is unique and easy to be distinguished.

Description

A kind of multi-functional warning megaphone of seeking help

Technical field

The utility model relates to a kind of alarm, specifically is a kind of multi-functional warning megaphone of seeking help.

Background technology

Current larceny case often occur in we the life around, most of people are more and more stronger to the prevention awareness of thievery, also appear at simultaneously various burglar alarms in the society, have and be specifically designed on the vehicle, also usefulness is specifically designed to family and public arena, alarm is of a great variety from function at present, use multiple high-tech means simultaneously, incident has played good effect to hitting out against theft etc., but because the alarm sound of alarm is more single, when burglar alarm is too much overstocked, in case just being difficult to distinguish actually that alarm when alarm sends alarm sound is calling out, the more ear-piercing certain noise pollution that causes that pipes of alarm brings some influences for our normal life simultaneously.

The utility model content

For overcoming above not enough the utility model present alarm has been carried out corresponding improvement, made its function more complete, burglar alarm is abundant in content, mode uniqueness, the characteristics of differentiating easily.The utility model is by the following technical solutions for achieving the above object:

A kind of multi-functional warning megaphone of seeking help comprises power supply, inductor and acoustical generator, is connected in series between the three, and it is characterized in that: described acoustical generator is the megaphone with sound-recording function, and described inductor is the switching regulator inductor.

Two ends at described megaphone also are connected in parallel to a luminophor.

Described inductor is the inductor of human induction switch formula.

Described inductor is the inductor of sonic-opticalcon trolled switch formula.

The inductor of described inductor magnetic resolution switching regulator.

The inductor of described inductor traction microswitch formula.

The utility model replaces single acoustical generator with the megaphone that has sound-recording function, so just own exclusive sound can be entered in the megaphone, when thievery takes place when, inductor can trigger megaphone energising work, at this moment propaganda directed to communicate and will send the sound of our prior typing, we are easy to tell the thievery of that place's generation actually like this, and react in time, have have a strong temperament, easily come into the picture; If we may also can't tell the spot of thievery the very first time only according to sound owing to the space is big in the open air in addition, at this moment we can also adopt luminophor and megaphone to cooperate jointly, in the time of the megaphone sounding luminophor of spot simultaneously witenagemot light luminously, we just readily appreciate that the spot like this.

The circuit connection diagram of Fig. 2, the open-air mode of the utility model.

Embodiment

As shown in Figure 1, 2, a kind of multi-functional warning megaphone of seeking help comprises power supply 1, inductor 2 and acoustical generator, is connected in series between the three, and described acoustical generator is the megaphone 3 with sound-recording function.

The utility model replaces single acoustical generator with the megaphone 3 that has sound-recording function, before installation, own exclusive sound is entered in the megaphone 3, when thievery takes place when, inductor 2 can trigger megaphone 3 energising work, at this moment megaphone 3 will send the sound of our prior typing, and we are easy to tell the thievery of that place's generation actually like this, and react in time, have have a strong temperament, easily come into the picture; Power supply 1 described in the utility model can adopt common household AC power, and on inductor 2 and megaphone 3 step-down transformer is set, and the selection of the occasion power supply that adapts in condition is more diversified.

For adapting to the needs of different environment, the utility model only needs inductor 2 to change, personnel in evening such as family, institutional settings, the shop inductor 2 of local adopted human induction switch formula of very much not coming in and going out for example, inductor 2 can send ultrared characteristics according to human body itself, in certain distance, will perceive in advance, and send the signal of warning.As can adopting the inductor of sonic-opticalcon trolled switch formula in some static relatively occasions, when the sound of environment reached certain decibel, newspaper inductor 2 will conducting, and 3 energisings of sense words device are propagandaed directed to communicate.And in occasions such as some stacked items such as warehouses, the utility model can adopt the inductor of magnetic resolution switching regulator, to around article be moved the magnetic resolution switch conducting that just is triggered time this moment, and then make megaphone work.The utility model also can be etc. in the building ground the local traction microswitch formula inductor that adopts, link to each other with traction microswitch formula inductor with fine rule around in advance in the building site, touching fine rule traction microswitch formula inductor as the people will move immediately, and megaphone sends the sound of propagandaing directed to communicate of warning.

The utility model during occasion, can also be parallel with luminophor 4 at the two ends of megaphone in the open air in addition, and when megaphone was propagandaed directed to communicate, luminophor 4 simultaneously also can be luminous, especially under the environment at night, the easier locale of distinguishing of indication of light arranged.

Claims (6)
