Abstract

The utility model relates to a sensing remotely controlled alarm which is mainly composed of a sensor, an amplifier, a rectifier, an oscillator and an emitting device of an emitter and a receiving device, an amplifier, a rectifier, an integrated block, a power amplification pushing device and a horn of a receiver. External information is sensed by the sensor of the emitter and then treated by the emitter. The emitter sends out radio signals to the receiver, after the signals are received and treated by the receiver, the music integrated block is pushed to send out signals to the horn, and the horn sends out alarm signals with specific music. The utility model has the advantages of simple structure, high alarm reliability and small volume, and is suitable for the anti-theft alarm for the important items in the places, such as banks, shops, houses, etc.

Description

Transduce remote controlled siren

The utility model relates to a kind of alarm, refers in particular to a kind ofly to respond to the vibration wave that air vibration produces and send the sensing remote annunciator of alerting signal.

At present, commercially available all kinds of alarms, just can sound the alarm after all needing the people to touch this alarm, though they can deter theft to a certain extent, but astute theft still can be avoided this alarm, reach the purpose of its stealing, thereby the accurate rate of its warning is descended, bring certain trouble and worry to the user.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and dependable performance is outwards sent the sensing remote annunciator of alerting signal by the induction air vibration.

The utility model is to adopt following proposal to realize: receive external information by inductor M, this information is amplified through triode, rectification, after the filtering, thereby amplify the DC relay work that makes through direct current again, connect the RLC oscillatory circuit, after high frequency modulated, send alerting signal to receiver, after receiver is received signal, through ic chip 1 signal being carried out height puts, mixing, local oscillator, in put, delivering to the amplifying circuit of being made up of triode behind the frequency discrimination amplifies, signal after the amplification is through rectification, trigger music integrated block IC 2 thereby amplify through direct current after the filtering, music signal promotes loudspeaker and outwards sends alerting signal after amplifying again.

Be provided with secret signal transmission, receiving trap in transmitter in the utility model and the receiver in order to difference robber and household.

The utlity model has simple in structure, warning reliability height, advantage such as volume is little, is easy to install, and is easy to carry is suitable for the burglar alarm to the important item on ground such as bank, shop, family.

Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
