The invention relates to an ultrasonic dog-expelling device produced by a monolithic integrated circuit. The ultrasonic dog-expelling device is composed of a power source DC, a key switch AN, a self-excitation multi-resonant oscillation circuit and an ultrasonic wave output circuit, wherein the self-excitation multi-resonant oscillation circuit is composed of a time-base circuit IC 1, a resistor R1, a resistor R2, a trimming resistor RP, a capacitor C1 and a capacitor C2; and an ultrasonic wave output transducer is a piezoelectric buzzer. According to the ultrasonic dog-expelling device provided by the invention, a device which can send out ultrasonic waves is used for expelling pet dogs to enter into specific fields or be closed to human bodies, so that the pet dogs can rapidly quiet down when the pet dogs are agitated. A lot of dog ears have strong responses to sounds of the ultrasonic waves with the frequency in a range of 15-25 kHz and the sounds of the ultrasonic waves can be used for better awing and threatening the pet dogs. The ultrasonic dog-expelling device is researched and designed according to the principle; a core circuit of the device is an ultrasonic wave generator with a larger power; high-frequency sounds which are sent by the ultrasonic wave generator can be used for expelling the pet dogs and the pet dogs can quiet down at night and do not bark at will; or stray dogs and vicious dogs in the street also can be surrendered.

Description

The ultrasonic dog expelling device that monolithic integrated optical circuit is made

Technical field

The invention belongs to electronics and technical field of ultrasonic application, is the ultrasonic dog expelling device of making about a kind of monolithic integrated optical circuit.

Background technology

Now more and more people hanker after the pet feeding dog; But must not expressly provide pet dog and get in public places such as a lot of stores, hotel, park; In the resident living sub-district; To night or the late into the night pet dog kyoodle " Wang Wang " and let the people be difficult to have a rest really, some is disliked dog even can damage or propagate rabies to human body, it is the most important to improve consciousness of keeping an eye on and the responsibility of strengthening the dog owner certainly.The present invention is intended to look for another way, with a kind of electronics mode send hyperacoustic device be used to drive pet dog near or the deterrence dog get into particular place, or excited pet dog can promptly be quieted down.

According to the data introduction, many animals are flourishing especially aspect the sense of hearing, can hear the sound of the human upper frequency of can't hear, and the frequency of the audibility range of animal is between 30～50kHz usually, and it is exactly around this principle to make that many business-like insects are driven device.Most of dog ear is responsive especially or respond strongly to the sound of 15 to 25kHz frequencies, and ultrasonic sound has good fright and threatening effect to pet dog.The present invention is by this Research on Principle design; Its core circuit is a supersonic generator that power is bigger, sends high-frequency sound (that is: ultrasonic) with it and drives pet dog, can let pet dog quiet down at night with it; No longer arbitrarily kyoodle, perhaps be used to subdue the invasion that some dislikes dog.

Those are feared that especially the Ms of dog is necessary to carry one and drives the dog device, be used to prevent that those disagreeable dogs are to your invasion and injury on the street.

Below specify the related correlation technique of ultrasonic dog expelling device in manufacturing process that this monolithic integrated optical circuit is made.

Summary of the invention

Goal of the invention and beneficial effect: the present invention is intended to look for another way, and can send hyperacoustic device and drives that pet dog gets into particular place or near human body, irritated pet dog can promptly be quieted down with a kind of.Most of dog ear is responsive especially or respond strongly to the sound of 15 to 25kHz frequencies, and ultrasonic sound has good fright and threatening effect to pet dog.The present invention is by this Research on Principle design, and its core circuit is a supersonic generator that power is bigger, and the ultrasonic output transducer is a piezoelectricity singing piece.Send high-frequency sound (that is: ultrasonic) with it and drive pet dog, can let pet dog quiet down, no longer arbitrarily kyoodle, perhaps be used to subdue the vagrant dog that goes up in the street and some dislikes the invasion of dog at night with it.

Description of drawings

Accompanying drawing 1 is the embodiment circuit working schematic diagram that the present invention provides the ultrasonic dog expelling device of a monolithic integrated optical circuit making; The negative pole of power supply DC in the accompanying drawing 1 links to each other with circuit ground GND.

Embodiment

Circuit working schematic diagram and description of drawings according to the ultrasonic dog expelling device of making for monolithic integrated optical circuit shown in the accompanying drawing 1; And according to the annexation between the components and parts in the described each several part circuit of summary of the invention, and the components and parts technical parameter described in the embodiment requires to implement to realize the present invention.

The selection of components and parts and technical parameter thereof

IC1 is a time base circuit, and model is NE555 or LM555, and packing forms is dual inline type 8 pin DIP encapsulation; Each pin function: 1 pin is circuit ground GND; 2 pin are trigger end; 3 pin outputs; 4 pin preset ends; 5 pin are control voltage; 6 pin thresholdings (threshold value); 7 pin are discharge end; 8 pin are positive source VCC;

Make general condensed summary and circuit debugging

1. require the parameter value of all components and parts accurate, otherwise frequency of oscillation is taken place than about-face.

2. the circuit welding of the ultrasonic dog expelling device of making at monolithic integrated optical circuit finishes, and all elements are as long as welding is errorless on inspection, and general circuit need not used debugging to connect power supply and get final product operate as normal.

3. in the adjustment process, to the adjustment of semifixed resistor: bigger resistance makes frequencies go lower.Because different dogs can produce reaction to different frequencies, need carry out suitable adjustment to circuit.Test whether circuit can both operate as normal under different frequencies.The frequency that semifixed resistor RP and capacitor C 1 produce is about 14HzK to 24kHz; The capacitance of capacitor C 1 is very crucial, and it has determined the frequency of oscillation of multi-harmonic self-excited oscillation circuit, the most ceramic disc capacitor less stable that works together, and error is about about 20%, so the polypropylene capactive of stable performance is adopted in suggestion; Capacitor C 1 capacitance value is bigger than normal, and then the frequency of oscillation of multi-harmonic self-excited oscillation circuit is lower; Because of the capacity of inconvenient trimming capacitor C 1 changes frequency of oscillation, so that suggestion adjustment semifixed resistor RP changes the frequency of oscillation of multi-harmonic self-excited oscillation circuit is more convenient.
