Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish collecting device, and more particularly to a fish collecting device that collects fish by utilizing sound waves.
Generally, when fish are hungry and have a good appetite,
It is considered to be a time when a fighting spirit was agitated, a time when curiosity or a play instinct was involved.

It is known that the distant fish find their food and come close to them firstly because of their visual sense, and at the same time, the smell that diffuses in water. Has been. Therefore, the basic principle of fishing is to first drop the fishing line at the point (point) where the fish gather, but it requires a great deal of skill to judge the point, and even if a beginner drops the fishing line blindly I can't catch

[0003] On the other hand, it is known that fish are equipped with auditory (tactile) nerves called lateral lines, which allow them to react sensitively to water flow, changes in water pressure, and low-frequency sway transmitted in water. Therefore, attempts have been made to gather fish by using sound waves.

[0004]

2. Description of the Related Art Conventionally, it is known that a hollow body is provided with a battery and a DC motor and an eccentric weight attached to a motor shaft is rotated to generate a low frequency vibration sound.

[0005]

However, in the system using the DC motor as the sound source as described above, the battery is consumed quickly and the weight of the fish collector becomes heavy, so that it cannot be used for throwing fishing and the like. Further, since the generated sound is regular and monotonous, there is a drawback that the effect of fish gathering cannot be sustained for a long time.

[0006] The purpose of the present invention is to be light and long-lasting function,
It is to provide a fish collector capable of sustaining the effect of catching fish.

[0007]

The above problems can be solved by, for example, the configuration shown in FIG. That is, the fish collector of the present invention (1) is a fish collector that collects fish by using sound waves. In the hollow body, the battery holder 9 that holds the battery 7 in a replaceable manner and the battery 7 as a drive source are used. And a sounding section 15 made of a piezoelectric element, and a filling material 23 is filled around the sounding section 15.

According to the present invention (1), since the piezoelectric element is used as the sound source, it is possible to provide a fish catcher which is lighter in weight and has a long-lasting function both electrically and mechanically as compared with the conventional one. In addition, since the filling material is filled around the sounding portion, the sounding portion can be protected from water infiltration, and desired low frequency sound waves obtained by utilizing the resonance effect in the sounding portion can be externally (underwater) through the filling material. ) Is efficiently transmitted to.

The above problem can be solved by, for example, the configuration of FIG. 2 or FIG. That is, the fish collector of the present invention (2) is a fish collector that collects fish using sound waves, and is supplied with power through the power supply control unit 151 that intermittently supplies the power of the battery 7 and the power supply control unit 151. In addition, a signal generation unit 152 that generates a periodic or pseudo-random pattern signal, and piezoelectric elements 155/165 and 166 that are driven by the pattern signal of the signal generation unit 152 are provided.

According to the present invention (2), the power supply controller 151.
Since the battery power is supplied intermittently, sound waves are also generated intermittently (irregularly), and thus the fish gathering effect can be sustained. Moreover, the battery life is extended. Further, since the signal generation unit is fed through the power feeding control unit and generates a periodic or pseudo-random pattern signal, it is closer to, for example, a sound wave having a periodic pattern that fish prefers, or an irregular operation in nature. Sound waves having such a pseudo random pattern can be easily generated.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Note that the same reference numerals indicate the same or corresponding parts throughout the drawings. FIG. 1 is a diagram showing a configuration of a fish collector according to an embodiment, and FIG.
Is a front view of the fish collector, FIG. 1 (B) is a side sectional view {FIG. 1 (A)
A sectional view along line aa}, and FIG. 1C is a rear view. The schematic dimensions (unit: mm) of the main part are added to the figure.

In the figure, 1 is a hollow body portion, 3 is a hollow lower lid portion, 5 is an upper lid portion, 7 is a columnar exchangeable battery (dry cell), 9 is a conductive battery holder, 11
Is a non-conductive support member, 13 is a printed circuit board, 15 is a sounding part, 17 is a red light emitting diode, and 19 is a body part 1.
And the lower lid portion 3 are joined together, 21 is a guide member provided at four corners of the inner wall of the body portion 1, 23 is a filler, 25 is a threaded portion between the body portion 1 and the upper lid portion 5, and 27 is a battery 7 pressing member. The spring member 29 to be added is a hole through which a fishing line or the like passes.

The body portion 1 and the lower lid portion 3 are made of, for example, ABS.
(Copolymer of Acrylonitrile, Butadiene, Styrene)
It is composed of a plastic member obtained by injection-molding a resin, and has excellent characteristics in which the chemical resistance and heat resistance of A, the impact resistance of B, the moldability and gloss of S, etc. are mixed. by the way,
Fish have a special color-sensitive property, and generally have a property of being attracted to red and white or a reddish color similar to the color of food. Therefore, for example, the body portion 1 and the lower lid portion 3 are formed of a plastic member such as glossy red and white or glossy yellow and white.
In this case, a fluorescent substance which is said to be preferred by fish (such as a fluorescent substance lumichrome or riboflavin separated from silkworm pupa) may be applied to the surface or mixed in a plastic member.

The tip portion (left side in the figure) of the lower lid portion 3 projects in a cylindrical shape, and the end portion thereof has a hemispherical shape so that the light of the light emitting diode 17 is uniformly emitted into the water. There is. Further, a light guide hole 31 is provided along the central axis of the tip portion.
Are provided to efficiently guide the light of the light emitting diode 17 to the hemispherical end portion. The upper lid portion 3 is made of a metal that does not rust (brass, stainless steel, etc.), and if necessary, a surface thereof is coated with, for example, a silver-colored paint that does not appear as foreign matter to fish even in water.

By the way, in the case where such a fish collecting device is tied in a mitchite for throwing, it is easier to handle if the fish collecting device has an appropriate weight. In this respect, the metallic upper lid portion 3 serves to give an appropriate weight to the entire fish collector. However, in this case, if the weight balance (center of gravity) of the fish collector is close to the side of the lower lid 3, a large load may be applied to the michiite by the moment force that swings the fish collector, and the michiite may be cut off. In this respect, the heavy upper lid portion 3 has an action of moving the center of gravity of the fish catcher to the side of the michiite. Therefore, even if the fish catcher swings during throwing, a large moment load is not applied to the michiite. Further, the weight of the upper lid portion 3 stabilizes the posture of the fish collector in water.

When manufacturing such a fish collector, the end of the battery holder 9 is externally inserted into the rear hole of the support member 11 and fixed by adhesion. Further, the printed board 13 on which the sounding portion 15 and the like are mounted in advance is positioned and inserted and fixed to the front convex portion of the support member 11. This completes the internal assembly. Further, insert the obtained internal assembly into the body 1 from the side of the battery holder 9,
The front end portion of the battery holder 9 is connected to the rear hole portion 33 of the body portion 1.
Insert At that time, the guide member 21 on the inner circumference of the body portion 1 guides and supports the sounding portion 15 at an appropriate position. Then, in order to prevent water from entering from the rear hole portion 33 of the body portion 1,
The hole 33 and the tip of the battery holder 9 are bonded and fixed.

Further, the light emitting diode 1 is attached to the head of the lower lid 3.
7 is inserted, and the lower lid portion 3 is adhesively fixed to the body portion 1. At that time, preferably, the hollow portions of the body portion 1 and the lower lid portion 3 are filled with a filling material (sealing material). Examples of the filler include epoxy resin and silicone resin which are often used in electronic devices. Although these have drawbacks in moisture resistance, there is no problem if they are inexpensive and the body 1 and the lower lid 3 are sufficiently sealed. If the inner assembly is potted with resin, the inner assembly can be protected from flooding,
Moreover, even if the fish collector is treated a little roughly, no functional disorder occurs.

A preferable filler is, for example, a filler having the same sound propagation characteristic as that of the lower lid portion 3 and the body portion 1 when solidified. In general, sound waves have a property of being lost when passing through different media. However, if a hollow body is filled with a filler having a property similar to that of the outer cover, sound waves of desired low frequency generated in the sounding unit 15 are effective in water. Can be communicated to. The filler may have elasticity (softness). In this case, the sounding part 15 is not sufficiently fixed to the body part 1, so that the sounding part 15 vibrates in the filling material. This mechanical vibration can be similar to the vibration when the fish is preying on the food, which is a preferable vibration for the fish collector.

FIG. 2 is a diagram showing a structure of a sounding unit according to the embodiment, and shows a case where a piezoelectric buzzer is used as a sounding body. In the figure, 151 is a power supply control unit, 152 is a signal generation unit, 153 is a balanced amplifier (AMP), 154 is a hollow resonance case, 155 is a disk-shaped thin plate (piezoelectric element) made of piezoelectric ceramics, 156 is brass, A disk-shaped metal plate made of stainless steel or the like, 157 is an electrode made of silver or the like.

The power supply control unit 151 supplies the DC power of the battery 7 to the load side intermittently (for example, every second for 2 seconds). The signal generator 152 is energized by the power supply from the DC power source to generate a periodic or pseudo-random pattern signal PN / WS.
Generate The balanced amplifier 153 converts the logic 1/0 level pattern signal PN / WS into a ± V balanced voltage signal.

In the piezoelectric buzzer, the thin plate 155 made of piezoelectric ceramic is attached to the metal plate 156 to form the element 1
The spreading vibration of 55 is converted into a flexural vibration to generate a sound wave. That is, since the piezoelectric element 155 has the spontaneous polarization P even when the external electric field E is not applied, it extends in the direction of the spontaneous polarization P and contracts in the vertical direction. In this state, when an electric field E is applied in the same direction as the spontaneous polarization P as shown in the figure, the element 1
55 further extends in the direction of the spontaneous polarization P (however, since it is thin, its displacement is small), and it further contracts (narrows) in the vertical direction. When an electric field E is applied in the direction opposite to the spontaneous polarization P, the element 155 contracts in the direction of the spontaneous polarization P and extends (expands) in the vertical direction.

Therefore, by applying an alternating electric field of ± E according to the pattern signal PN / WS from the balanced amplifier 153, a sound wave corresponding to the pattern signal PN / WS is generated. Then, the case 154 resonates with a desired low-frequency component and dissipates the sound wave energy to the outside. As the material of the case 154, for example, glass, metal,
Various materials such as ceramics (pottery) can be selected.

The size of the case 154 is preferably as large as possible in order to extract low-frequency components, for example, the size may be such that the case 154 expands in the hollow portion of the fish collector body. In response to this, the size of the piezoelectric element 155 (that is, flexural vibration) also increases, and a large sound pressure is obtained. The light emitting diode 17 of this example is designed to blink in accordance with a pattern signal PN described later, but it may be connected to the power feeding control unit 151 to blink intermittently, or may be connected to the battery 7 for constant lighting. It may be turned on.

FIG. 3 is a diagram for explaining the signal generator according to the embodiment and shows a case where the pseudo random signal PN is generated. FIG. 3A is a block diagram of the signal generation unit 152. In the drawing, FF1 to FF4 are flip-flop circuits, O is an OR gate circuit, EO is an EX-OR gate circuit, and OSC is a low frequency oscillator.

FIG. 3B shows an operation truth table of the signal generator 152. When the signal generator 152 is supplied with DC power, a power-on reset circuit (not shown) energizes the reset signal RS for a predetermined time, and then only one trigger signal TG1 is input. As a result, at the timing of the first clock signal CK1, only the output signal Q1 of FF1 becomes ON (= 1), and the next clock signal CK1
At the timing of 2, only the output signal Q2 of FF2 is turned on. Below, the circuit operates according to the circuit diagram, and in this example, the clock signal CK1
It returns to the same state as the timing of. Then, in the section of T1, the pattern signal PN1 as shown in the figure is obtained at the output of the EX-OR gate circuit, and this has a pseudo random pattern.

Although the figure shows the case where the FF has four stages for the sake of simplicity of explanation, if the number of stages of the FF (the degree of the generator polynomial) is increased, a pseudo random pattern with a long period can be obtained, which is substantially the same. Can be thought of as a random pattern. In this case, if the frequency of the clock signal CK is selected relatively fast, the piezoelectric buzzer can be directly driven by the pseudo random pattern signal PN. The sound waves in this case are irregular (pseudo-random) sound waves with wave intervals as shown in FIG.

Alternatively, the frequency of the clock signal CK may be sufficiently slowed and the oscillation of the low frequency oscillator OSC may be activated / deactivated by the obtained pseudo random pattern signal PN. The oscillation signal WS in this case is PN =
It oscillates at a low frequency in the section 1 and does not oscillate in the section PN = 0. Therefore, when the piezoelectric buzzer is driven by this oscillation signal WS, the sound wave is such that a constant low frequency sound wave is generated at irregular intervals and intervals.

In any of the above, such a sound wave is a low-frequency sound wave that stimulates the lateral line of the fish, and since it has irregularities, it is closer to the movement in nature,
Without getting tired of fish, you can expect a long-lasting effect. Also, since the pseudo random pattern generation circuit is simple, it can be easily incorporated into a small fish collector.

By the way, FF4 as shown in FIG.
Even with a circuit having a simple stage, by removing the reset signal RS from FF1 to FF4, the irregularity of sound waves can be substantially increased (more randomized). In this case, assuming that the signals Q1 to Q4 = 0 at a certain power supply start time, the trigger signal TG1 at that time generates a pseudo random signal PN1 having a phase as shown in the section T1. Then, once the DC power supply is turned off and power is supplied again, FF1 to FF4 are not reset at the next power supply start time.
The states of the signals Q1 to Q4 are irregular. That is, assuming that the signals Q1, Q4 = 0 and the signals Q2, Q3 = 1, for example, the trigger signal TG2 at that time generates a pseudo random signal PN2 having a phase as shown in the section T2.

Then, the pseudo random signals PN1 and PN2
Considering a case where and are connected in time series, these pattern shapes are different as shown in the figure, so that the irregularity of the sound wave as a whole can be substantially increased. FIG. 4 is a diagram showing a configuration of a sounding section according to another embodiment, and here shows a case where a bimorph is used as a sounding body.

In the figure, reference numeral 164 designates a case made of metal, ceramics, glass, wood, plastic or the like, 1
Reference numerals 65 and 166 are rectangular thin plates (piezoelectric elements) made of piezoelectric ceramics, 167 are elastic metal plates (conductive layers), 16
Reference numerals 8 and 169 are electrodes made of silver or the like, and 170 is a sounding piece made of metal, ceramics, glass, wood, plastic or the like.

The configuration and operation of the power feeding control unit 151 to the balanced amplifier 153 may be the same as in the case of FIG. The bimorph is a device in which elements 165 and 166 having a spontaneous polarization P are attached via a conductive layer 167 as shown in the figure. The upper end of the bimorph is fixed to the case 164, and the alternating electric field E is applied to the bimorph.
Is applied.

In this case, the piezoelectric elements 165 and 166 extend in the direction of the spontaneous polarization P and contract in the direction perpendicular to the spontaneous polarization P when the external electric field E is not applied. In this state, when an electric field E in the positive direction is applied as shown in the figure, the element 165 expands in the direction of the spontaneous polarization P and contracts in the vertical direction. On the other hand, the element 166 contracts in the direction of the spontaneous polarization P and extends in the vertical direction. As a result, the bimorph bends to the left. When the electric field E is applied in the direction opposite to the figure, the element 165 contracts in the direction of the spontaneous polarization P and expands in the vertical direction. On the other hand, the element 166 extends in the direction of the spontaneous polarization P and contracts in the vertical direction. As a result, the bimorph bends to the right.

Utilizing the bending displacement of the bimorph as described above, the sounding piece 170 provided at the lower end of the bimorph collides with the opening end of the case 164 to generate a sound wave. Various tones can be obtained by selecting the material of the opening end of the case and the sounding piece 170. The sound wave is radiated to the outside through the case 164 having a size, shape, and material in consideration of resonance. FIG. 5: is a figure explaining the usage example of the fish collector by embodiment.

FIG. 5 (A) shows a case of breakwater fishing. For example, a weight is hung on a snow tackle and floated on the water surface, and the fish collector is adjusted to an appropriate depth. The fisherman hangs a line separately near the fisherman and waits for the fish to gather. FIG. 5 (B) shows a case of throwing fishing, in which a fish collecting device is tied up in the middle of Michiite and thrown into the sea together with the weight.
The weight and the weight of the fish collector can be combined to set the moss at a desired position.

In the above embodiment, the power supply controller 15
Although the case where 1 and the signal generation unit 152 are provided is described, the present invention is not limited to this. For example, even if the power supply control unit 151 is omitted, the signal generation unit 152 can generate a low-frequency sound wave having a periodic or substantially pseudo-random pattern suitable for catching fish. Alternatively, even if the signal generator 152 is omitted, the power supply controller 151 can generate low-frequency sound waves having an intermittent pattern. Alternatively, even if the power feeding control unit 151 and the signal generation unit 152 (excluding the low frequency oscillator) are omitted, a constant low frequency sound wave can be efficiently generated.

Further, although the irregular sound waves are generated in the above-mentioned embodiment, a constant periodic pattern signal suitable for fish gathering may be generated. In this case, the periodic pattern signal is stored in, for example, a non-volatile memory (ROM, EEPROM, etc.) provided in the sound generator 15 and is read out continuously or intermittently. Although the preferred embodiments of the present invention have been described, it goes without saying that various changes in the configuration, control, and combinations thereof can be made without departing from the spirit of the present invention.

[0038]

As described above, according to the present invention, it is possible to provide a fish collector which is light in weight, consumes less power, and can maintain the effect of catching fish, and even beginners can enjoy the real pleasure of fishing.
