Abstract

For increasing the efficient of audible drive, enlarge its range of application, the present invention proposes the multifunctional audible drive method and use the special equipment of this method.The multifunctional audible drive method adopts the different signals of driveing to come insects such as mosquito repellent, mouse targetedly, and has proposed to utilize radio network to realize that the sound equipment in vast rural area drives evil.Use the special equipment of this method to comprise a kind of recording box general, work capable of circulation.The present invention can carry out sound equipment effectively and drive evil in the rural area, comprise driving bird and driveing other harmful insect, can be used for luring collection various poultry, domestic animal and fish.

Description

Multifunctional audible drive technique

The invention relates to sound or ultrasonic and drive the method for various insects and animal and the invention of special equipment thereof.

From the midsummer to the late autumn, wonderful tonight brings the unlimited joy of life and quiet to people.Yet when being, the invasion of mosquito can't be broken away from many places.People have begun to adopt sound and ultrasonic to come repel mosquitoes, and this method utilizes insect and animal (as mosquito, mouse) to have some sound of escape or hyperacoustic characteristics, drives insect and animal with sound or ultrasonic.Here being called for short this method is audible drive, and all insect and animals of being driven are referred to as insect.Here " drive " and refer to insect is driven away from some zone, or be introduced into some zone.Audible drive has advantages such as easy to use and side effect is little, and has the potentiality that dispersion effect is good, scope is wide, cost is low.But present some audible drive device (warding off as sound mosquito expelling equipment, ultrasonic rat repellent) can not accomplish to adopt targetedly the suitableeest signal, does not therefore reach gratifying dispersion effect.In addition, play the mosquito repellent signal with the radio station and can consequently can not drive multiple mosquito most effectively simultaneously because the area is too big; In order to strengthen the efficient of sound equipment mosquito repellent, further promote audible drive technique, invent out multifunctional audible drive method and the special equipment that makes in this way.This multifunctional audible drive method is utilized alternative signal source to strengthen and is driven efficient, these signals can be the sound or the ultrasonic (this can enroll from relevant laboratory) of nature, also can be the little sound of distortion by the signal generator acquisition of precision.And this method further proposes to utilize various existing stereo sets, as some link and the device of wired broadcast system, comprises the audio signal amplification, and output element and electro-acoustic transducer device carry out audible drive; Can certainly utilize its power supply, casing and information pickup link.On the broadcasting mode, can adopt simultaneously or the mode of playing in turn the various sound that are used to drive and they and other sound.Can certainly design and installation one overlap the audible drive device of the special use of using the multifunctional audible drive method.

The function of above-mentioned audible drive device is similar to recorder, is used to write down, take out or produces the various signals that are used for pest repelling.It comprises various information storages and output block, signal amplification or treatment circuit and electroacoustic transduction element.But the special equipment that uses in general, the multifunctional audible drive method comprises the record of driveing signal and takes out parts or drive signal generator.Drive signal pin to the different objects of driveing, its content has nothing in common with each other: for mosquito, utilize female mosquito period of pregnancy (only they are just sucked blood desperately) to want to do one's utmost to avoid this specific character of male mosquito, play sound such as the flight sound of male mosquito and driven; Can play the ultrasonic that the bat as its natural enemy sends for all kinds of insects; The cat of sound can play to(for) mouse is as pouncing on food sound; Can play the unexpected bat sound of warding off for birds waits and carries out audible drive.In like manner can drive insect or insects such as fly in this way, also can trap various insects, snake class (they have the instinct near frog sound) and fish in this way or convene various domestic birds and animals.Therefore audible drive of the present invention comprises the sound equipment trapping and convenes these functions.In general, unartificial sound is all simulated, thereby drives signal and adopt analog form with the stronger physiological reflex effect of generation for fidelity, but does not get rid of non-analog signal, and its concrete processing can be with reference to the processing of this paper to analog signal.

The record analog signal can adopt ready-made various recording devices.As disc or audiotape, also can be improved various sound pick-up outfits from the frequency response angle.The recording device of designing constantly loop playback in addition uses with convenient, and embodiment one and two provides two specific designs.

Embodiment one is the disc that information driven in a kind of record, and it has the recording groove of sealing.

Embodiment two is a kind of cassette tapes, and it only has the end to end tape of a circle to write down and drive signal, and it can exchange with common cassette tape and use.

For cost and the volume that further reduces the equipment of driveing, the present invention proposes to drive recording medium with a kind of Piezoelectric Driving machine.The Piezoelectric Driving machine uses variable-frequency power sources, and the motor conversion efficiency is 25%～50%.Export oriented power or the moment of tens of milliwatts to hundreds of milliwatts, its volume minimum is 5 * 5(drive surface) * the 3(height) the cubic meter millimeter.And has a control accuracy advantages of higher.Concrete technology discloses in " Piezoelectric Driving machine " application for a patent for invention file.

One of advantage of the present invention-multifunctional audible drive technique is to realize sound equipment mosquito repellent and rat destruction as long as very little cost almost just can be equipped with the vast rural area of cable radio network overnight in the whole nation.Grain loss that can reduce more than one hundred million units every year of rat destruction only.Many places, the whole world: all can drive the mouse of going out in this way as electric control room, warehouse etc.; Realize that the sound equipment mosquito repellent can reduce disease, healthy.

One of optimum implementation of the present invention is the loop playback cassette to be put into recorder realize that sound drives.

Two of preferred plan is that loudspeaker and volume input control line are drawn out to the independent signal source of driveing with the power supply with stereo set (warding off as portable radio) such as attaching socket.This signal source comprises Piezoelectric Driving machine and special-purpose variable-frequency power sources and simple and easy audiohead, cyclic tape and level holding circuit etc.Both are in conjunction with realizing audible drive.

In addition, ultrasonic signal can suppress or comes bypass so that rejected when the radio reception with electric capacity with inductance.The arrangement that difference is driven the electro-acoustic transducer device of object also can redesign to obtain better effect.
