Description

The present invention relates to strike by hanging fish is converted into sound, the bite acoustic system which transmits the fisherman as a sound together with the vibration of the strike.

  In general, when a fish is caught on a fishing rod, the angler empirically estimates the type and size of the caught fish from the strength of pulling by the fish and the vibration generated by the fish, so-called fish trust. Similarly, when a trap is applied to a rock or obstacle existing on the riverbed or seabed such as a root hook, the tip of the rod is pulled in, but a vibration different from that of the fish is generated in the fishing rod. For anglers with little experience in actual fishing, it is useful just to be able to judge whether the fish is a root or not by vibration.

  For example, Patent Document 1 discloses that a coil formed by winding a conducting wire around a bobbin or the like in a fishing rod bottom (grip) formed hollow, and a winding direction of the conducting wire disposed near the coil. A support portion that cantilever supports a bar magnet that swings in the intersecting direction, an amplifier that amplifies the induced current generated in the coil as the bar magnet swings, and an output terminal that outputs the amplified induced current to the outside, or A speaker that emits sound is housed. In this fishing rod, an induced current corresponding to the vibration generated in the butt is generated and transmitted as a sound to the angler.

  Further, in Patent Document 2, when a fish is caught on a fishing rod with a reel mounted on a rod stand or the like on a rod or a quay, the fish signal is converted into a radio signal and received. There is a known system that notifies the angler with a sound by sound.

JP 2005-73665 A JP 2005-58197 A

  The above-described cantilevered bar magnet described in Patent Document 1 is configured to generate an induced current by swinging in the vicinity of the coil according to the vibration of the fishing rod. In such a configuration, the vibration of the fishing rod and the vibration of the bar magnet do not necessarily match due to the weight of the bar magnet. That is, depending on how the fishing rod vibrates (frequency), the support portion of the bar magnet precedes the vibration, and the tip (non-support portion) of the bar magnet subsequently vibrates. Therefore, it becomes a case where the vibration of the rod bottom is preceded by the vibration of the rod butt and the vibration of the fishing rod itself is suppressed.

  In general, when the type of fishing rod (such as a hanging curve) changes, even if there are differences in sensitivity or subtle sensations, it is possible to feel that there is a difference in fish trust due to the difference in fish type. It is possible to guess the size. However, when the fishing rod itself changes the vibration, the fishing rod vibration is different from the actual fish faith. I don't know the size. In other words, the vibration generating mechanism itself changes the original vibration of the fishing rod depending on the situation, and the vibration noise often causes confusion.

  In addition, in the configuration example in which the vibration of the fishing rod is heard with the earphone, since the line is connected to the bottom of the fishing rod, when the fishing rod moves greatly by lifting the fishing rod, It is assumed that the earphone is pulled out of the ear. If the earphone cable is lengthened, it will be caught by surrounding objects, making it inconvenient. Furthermore, in the configuration in which the speaker is housed in a fishing rod, it is not easy to use a waterproof mechanism, and it becomes difficult to wash the fishing rod when cleaning it. Furthermore, it is difficult to generate a large volume from the built-in speaker, and a situation where it cannot be heard due to ambient noise is also assumed.

In Cited Document 2, since the reel (spinning reel) and the fishing line guide are used, it cannot be applied to a fishing rod that does not use a reel or a fishing line guide, such as a mountain stream rod or a rod.
The present invention is compact and cordless, without limitation of the type of fishing rod, if there is a hollow storage space in the fishing rod can be easily applied, provides a bite sound system to achieve a good maneuverability fishing rod The purpose is to do.

In order to achieve the above object, an embodiment according to the present invention is attached to a flat surface provided on a wall surface inside a hollow of a fishing rod, and causes vibration generated at the tip of the fishing rod to extend from the tip of the fishing rod. A first vibration that is a fish belief by the fish that has been hung and a second vibration that is generated by an obstacle other than the fish that has been hung on the mechanism as a sound signal; and a microphone that is disposed in the fishing rod, a transmission unit that transmits to convert the Kion signal before obtained by the microphone to a radio signal, provided separately from the transmission unit, receives a radio signal transmitted from the transmitting unit, the first vibration And the second vibration, and at least the first vibration is demodulated into a sound signal as a fish signal by the fish , and the terminal is detachably connected to the receiver and is reproduced by the receiver. Output sound signal Providing strike acoustic system comprising a forming unit.

According to the present invention, a compact and cordless, without limitation of the type of fishing rod, if there is a hollow storage space in the fishing rod can be easily applied, the strike sound system to achieve a good maneuverability fishing rod Can be provided.

[First Embodiment]
FIG. 1 is a diagram showing an example of the overall configuration of a fishing rod equipped with a fish faith acoustic system (hereinafter referred to as an acoustic system) according to a first embodiment of the present invention, and FIG. 2 is a fish housed in the fishing rod. FIG. 3 is a diagram showing a conceptual arrangement configuration of the transmission acoustic system, and FIG. 3 is a diagram showing an arrangement state of microphones (hereinafter referred to as microphones). FIG. 4 is a diagram illustrating a configuration example of a communication device.

  The acoustic system according to the present embodiment is detachable from the signal detection transmitter 3 which is a transmitter provided inside the butt end of the fishing rod 1, a portable receiver 2 for wireless communication, and the receiver 2. It is comprised with the earphone 4 connected. In the present embodiment described below, the signal detection transmitter 3 is housed inside the buttock side, but is not limited to this position, and is limited to the space due to the inner diameter of the tube, such as the heel side. However, if it is in the hollow of a fishing rod, it can change suitably by devising arrangement | positioning of each structure part, It is not limited. Further, the fishing rod is preferably formed of a material having good vibration transmission. For example, a fishing rod formed of a carbon fiber sheet having a high elastic modulus E is suitable.

  In the present embodiment, a load is applied to the fishing rod 1, and the electrical signal is generated by changing the capacitance by changing the distance between the electrodes by using the strength of the pulling when the rod tip is pulled and the vibration generated in the fishing rod. Is acquired by a device that performs the operation, for example, a microphone, is acquired as a sound signal (an electric signal in an audible frequency band), and is further converted into a radio signal, for example, an FM radio signal by a transmitter, and wirelessly transmitted to the receiver side. . The receiver side can demodulate the received radio signal, convert it into a sound signal, and listen to the vibration of the fishing rod as sound by the earphone which is the sound signal generation unit. In the following description, the vibration generated in the fishing rod is acquired by a microphone and the signal converted into an electric signal is referred to as a sound signal. When the angler listens to the sound reproduced by the earphone from the sound signal, it is called listening (listening and listening to the sound).

  In the present embodiment, the earphone (small sound signal generation unit) has a drip-proof structure, and reproduces sound having a reproduction frequency band of at least about 15 Hz to about 100 Hz. Of course, it is not limited to this reproduction frequency band, and if it is a dedicated rod, it should just have the frequency band which can cover the vibration which an object fish generates. In other words, the vibration may be selectively created so that the sound can be heard with bias toward the fish faith (first vibration) by the fish that is the target fish for each fishing rod. For example, if a fish shin sound system is installed on a coral, the vibration (including the case where a trap is trapped by a stone or an obstacle in the river at the bottom of the river is selectively emphasized). (2) may be directed to make a judgment different from the above, or to the angler without generating a sound. If the frequency (frequency) acquired by the microphone is not in the audible frequency band, the sound may be generated by shifting to an arbitrary frequency within the audible frequency band.

  The signal detection transmitter 3 includes a microphone 11, a sound signal amplification unit 12, a transmission unit 13, a transmission antenna 14, a power source 15, and a selection switch 16. These components are configured by being mounted on a printed board (not shown). The receiver 2 includes a receiving antenna 21, a receiving unit 22, an amplifying unit 23, and a power source 24. As the power source, a general battery (button battery, lithium battery, etc.) is used, and the battery can be replaced more easily by providing a removable battery chamber cover (not shown).

  In the present embodiment, the microphone 11 is a capacitive microphone, for example, an electret condenser microphone (ECM). In addition, a contact microphone, a close-talking microphone, a carbon microphone, a piezoelectric microphone, or the like can be applied. The sound signal amplification unit 12 amplifies the sound signal detected by the microphone 11. As shown in FIG. 3, the microphone 11 forms a flat surface inside the fishing rod 1 and is provided so that the microphone 11 is in close contact with the flat surface to efficiently pick up vibrations generated in the fishing rod 1. In this embodiment, when the flat surface is formed, the inside is densely formed with a resin member. However, a gap is provided inside the flat surface, the flat surface is formed in layers, and sound is transmitted. Also good.

Since the sound signal output from the microphone 11 is a minute signal, the sound signal amplifying unit 12 amplifies the sound signal as a previous step.
The transmission unit 13 has a known configuration and includes a variable reactance unit 31, an LC transmission unit 32, a frequency multiplication unit 33, a switching unit 34, an AFC circuit 35, and a power amplification unit 36, as shown in FIG. . The switching unit 34 sets channels to be used from a plurality of preset channels so that the variable reactance unit 31 has different transmission frequencies so that interference does not occur when a plurality of transmitters approach each other. The switching unit 34 sets a channel to be used by a selection operation of the selection switch 16 provided at the bottom of the buttock.

  The receiving unit 22 is also a known configuration, and includes a high frequency amplifying unit 41, a frequency converting unit 42, an intermediate wave amplifying unit 43, an amplitude limiting unit 44, a frequency discriminating unit 45, and a de-emphasis unit 46. A filter (not shown) such as a bandpass filter may be added to the receiving unit 22 to extract only the fish band based on actual fishing and convert it into a sound signal.

  The power source 15 uses the same battery as the power source 24 of the receiver 2 and opens and loads the lid 18 provided at the bottom of the buttock. A packing member 19 made of rubber or resin is interposed between the lid 18 and the bottom of the buttock. When the lid 18 is closed, the inside of the buttock has a watertight structure, Prevent water from entering inside. In addition, a separation wall is provided inside the rod so that water or the like does not reach the signal detection transmitter 3 from the opening of the fishing rod seam.

  The amplifying unit 23 is a low-frequency amplifying unit that amplifies a sound signal for output to the earphone 4. Further, by providing a volume (not shown), the volume of the earphone 4 can be adjusted. Note that the sound emitted from the earphone 4 may be a buzzer sound, a sound of a musical instrument, a melody sound, an announcement guide (voice), and the like, and is output depending on the strength of the sound and / or the change in the pitch of the sound.

  Further, in the present embodiment, the signal detection transmitter 3 integrated with the microphone is arranged in the buttock, but is not limited to such an arrangement. For example, the microphone and the signal detection transmitter 3 may be configured separately and connected in a line, and the attachment position of the microphone may be disposed closer to the tip than the angler's grip on the fishing rod. In addition, if the frequency of the fish shin is known, the vibration can be detected efficiently by placing a microphone at a position in the fishing rod that is the antinode (the portion with the largest amplitude) of the vibration transmitted to the fishing rod. It is also possible.

  As explained above, the fisherman and the size of the fisherman were estimated based on the vibration transmitted from the fishing rod and how the tip of the rod was drawn. In addition to these, information (judgment material) by listening to the sound based on fish faith will be added, and for the angler, the vibration applied to the fishing rod and the load applied to the grip of the fishing rod, In addition to the shape of the hook that is drawn visually (hanging curve), new information (judgment material) is given, which is a sound based on the fish faith given as the listening sound. Will become more reliable and you can enjoy actual fishing more.

  Further, since the transmitter and the receiver provided in the fishing rod transmit information by cordless wireless communication, they can be handled in the same manner as a conventional fishing rod handling. In addition, since the receiver is small and lightweight, it can be stowed in a jacket pocket as with a portable audio device, and the earphone cord does not get in the way. The power source for the transmitter and receiver can use a commercially available battery, is easy to replace, and is easy to use. Furthermore, inexperienced anglers can obtain support through listening to determine whether the vibration generated in the fishing rod is fish or not, and whether the device is rooted in a foreign object or stone. It is one of the help.

A modification of the first embodiment will be described with reference to FIG.
FIG. 5 is a diagram illustrating a modification of the fish shin sound system according to the first embodiment. In the first embodiment described above, the receiver is a small receiver that is attached to or stored in clothes such as a vest. However, in the present modification, the receiver is attached to a hat and is listened to by an earphone. . The configuration of the fish shin sound system of this modification is the same as that of the first embodiment described above, and a description thereof is omitted here.

  According to this modification, the receiver 2 is attached to the cap 51, and the inside of the cap 51 is routed so that the earphone cord of the earphone 4 is pulled out from the side of the cap 51 from the receiver 2, that is, from the side of the ear. By this wiring, the earphone 4 and the ear are at the shortest distance, so that the exposed portion of the cord is reduced, the earphone cord is not caught on the arm or surrounding objects, and does not get in the way at all.

Next, a second embodiment will be described.
In the first embodiment described above, the transmitter microphone is directly attached to the inside of the fishing rod. On the other hand, in the present embodiment, the microphone is provided with a sound collector. FIG. 6 is a diagram showing a conceptual arrangement configuration of the fish faith acoustic system housed in a fishing rod. In the components shown in FIG. 6, the same components as those of the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 6, the microphone 11 is supported substantially at the center by a plurality of bar-shaped support members 62 in the fishing rod. The microphone 11 is preferably supported by at least three or more support members 62. A horn-shaped (trumpet-shaped) sound collecting portion 61 is provided on the front side of the tip. The sound collection unit 61 has a bottom 61b formed on a flat surface, and is attached so that the microphone 11 is in close contact therewith. In addition, the outer peripheral portion of the horn that extends from the bottom 61b and extends forms a flange portion 61a having a cylindrical width, and this flange portion 61a is provided in close contact with the inner wall surface of the flange. The sound collection unit 61 is formed of a hard resin member such as carbon or a metal member similar to a fishing rod.

  According to the configuration of the present embodiment, the vibration generated in the fishing rod is transmitted from the horn so as to be collected at the bottom 61b of the sound collecting unit 61, and picked up by the microphone 11 at the bottom 61b.振動 Since the vibration can be taken into the microphone 11 from the entire periphery, even if the vibration itself is weak, it can be taken in efficiently. It is also possible to selectively collect desired vibration frequencies by adjusting the spread angle from the bottom 11b to the outer periphery of the horn.

In addition, the structure which provided the lightweight small speaker in the receiver instead of the earphone may be included including this embodiment and 1st Embodiment mentioned above and its modification. Of course, the speaker may be integrated with the receiver, or a small and light portable speaker connected by a cable separately, for example, a speaker that can be pinned to clothes or a fishing vest near the ear may be used. . In the case where a speaker is used at the ear, the troublesomeness with respect to the wearing of the earphone is eliminated.
In the above-described embodiment, one transmitter and one receiver are described as one set. However, a single fishing rod, that is, one transmitter, is used with a plurality of receivers. Can also be received. In the present embodiment, the fish sound is converted into a sound signal and reproduced by the earphone, and the vibration sound is generated as an audible frequency band sound. Various expression methods such as a buzzer sound with a different tone, a buzzer sound in which different tones (scales) are mixed, a melody sound of an arbitrary song, a preset message (voice), and the like can be adopted.
