Description

Sound effect generator for simulated gun

The present invention comprises a transmitting unit equipped on the gun body side and a receiving unit arranged at a position away from the gun body. The transmitting unit is activated by a firing operation on the gun body side, and the receiving unit The present invention relates to a sound effect generator for a simulated gun that generates sound.

So-called electric guns, airsoft guns, or model guns are accepted by society beyond just toys. For example, some of the applicant's products are also delivered to government agencies such as the Ministry of Defense, where they are used for close combat training. These guns are also called simulated guns compared to real guns, but the difference remains that the firing sound is completely different from real guns.

Of course, a mock gun that can generate sound is also proposed. However, since they have built a small speaker inside the gun, there is a problem that a powerful firing sound cannot be obtained, and it cannot be applied to anything other than a large gun with a built-in space. On the other hand, the invention of Japanese Patent Laid-Open No. 6-66497 discloses an apparatus that selectively generates one shooting sound from a plurality of shooting sounds when a bullet is fired. Since the present invention does not incorporate a sounding device, a speaker, or the like inside the gun, there is no restriction that the external shape of the gun is not impaired and a small speaker must be used. However, since it is a play gun attached to the control box with a flexible pipe, carrying a gun has not been considered from the beginning, and it is difficult to apply to a simulated gun that is often made to imitate an actual gun It is.

In addition, Utility Model Registration No. 3057385 has the idea of transmitting the sound chip output of the bullet firing sound provided inside the gun toy by FM radio waves and placing a large speaker nearby. The transmitted radio wave is received by an FM stereo receiver or the like, and the audio reproduction frequency band can be corrected by a graphic equalizer or the like provided in the receiver, so that the gun firing sound can be reproduced more realistically. Therefore, although it is possible to generate a large volume, since the sound chip output of bullet firing sound is transmitted and received with FM radio waves, the receiver may pick up noise, which causes noise deterioration due to noise mixing. There are drawbacks. For this reason, a problem remains in sound quality, and even if a large sound volume can be generated, it cannot be said that the intended acoustic effect can be obtained.

JP-A-6-66497 Utility model registration No. 3057385

The present invention has been made in view of the above circumstances, and its object is to provide a sound effect generating device for a highly-preferred simulated gun that can hear a powerful fire sound equivalent to real fire by a fire operation. That is. Another object of the present invention is to make it possible to use a small receiver and headphones so as to generate a realistic sound in a survival game or shooting competition.

In order to solve the above-mentioned problems, the present invention comprises a transmission unit equipped on the gun body side and a reception unit arranged at a position away from the gun body, and activates the transmission unit by a firing operation on the gun body side. For the sound effect generator in the simulated gun that generates the firing sound at the receiving unit, as the transmitting unit, the vibration detection sensor that detects the vibration generated in the gun body by the firing operation, and the vibration detected by the vibration detection sensor A control circuit that receives a weak radio wave transmitted from a transmission unit and reads out sound effect data stored in a storage device, and a weak radio wave transmission unit that transmits a weak radio wave as an ON signal And a means for generating a sound effect for enabling the read data to be listened to.

The apparatus of the present invention is intended for a simulated gun, and activates a transmitter on the side of the gun body by a firing operation and activates a receiver arranged away from the gun body. The firing operation is triggered by a simulated gun firing device. As the firing operation, for example, various operation modes such as pulling a trigger or pressing a switch can be taken. This is one of the characteristics.

Therefore, a vibration detection sensor for detecting the vibration generated in the gun body is used for the transmitter. As the vibration detection sensor, it is desirable to use a piezoelectric element that converts a vibration generated on the gun body side by a firing operation into a signal voltage. In order to match the sensitivity of the vibration detection sensor with the vibration at the time of bullet firing, it is desirable to arrange the vibration detection sensor in a range substantially perpendicular to or substantially parallel to the bullet firing direction.

It is effective to distinguish whether the vibration is due to the firing operation or simply due to the impact applied to the gun and pay attention to the difference in the frequency in order to prevent malfunction. When the vibration detection sensor is a piezoelectric element, a sensor amplifier that amplifies the signal voltage converted by the piezoelectric element is provided, and the sensor amplifier also functions as a frequency filter that amplifies vibration of 70 to 80 Hz. It is desirable to do. It has been confirmed by tests that the above numerical range is the frequency at which the difference between when the simulated gun is touched and when it is fired is the easiest to distinguish.

The transmission unit includes a weak radio wave transmission unit that transmits an ON signal as a weak radio wave based on the vibration detected by the vibration detection sensor. By using the weak radio wave as the ON signal, for example, the mixing of noise can be significantly reduced as compared with transmission / reception using FM radio waves.

The present invention, as a receiving unit, receives a weak radio wave transmitted from a transmitting unit, reads out sound effect data stored in a storage device, and listens to the read data through an amplifier. And a sound effect generator for enabling the sound effect. The sound effect generating unit may use a headphone or a speaker, and the headphone or the speaker may be connected to the receiving unit by wire. In addition, the storage device can record a plurality of types of sound effect data.

Furthermore, the transmission unit in the present invention is composed of a vibration detection sensor and a weak radio wave transmission unit, and only requires a small installation space, so it can be built in the gun body. However, when it is equipped on the gun body side, it does not only refer to the inside of the gun body, but it is incorporated into parts and members including grips, silencers, tracers, flashlights, laser sights, and sighting devices attached to the gun body. It is also planned.

Since the present invention is configured and operates as described above, it is possible to listen to a powerful launch sound equivalent to a real fire by a launch operation, and the presence of noise is greatly reduced as the launch sound. A sound effect can be obtained, and a sound effect generator for a simulated gun with high taste can be obtained. In addition, according to the present invention, since a small receiving unit and headphones can be used, there is an effect that a sound can be generated in a survival game or a shooting competition. According to the present invention, a realistic sound can be obtained in this way, which is useful for cultivating a sense of tension when handling a real gun using a simulated gun.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of the electrical configuration of a sound effect generator 10 in a simulated gun according to the present invention. The device 10 of the present invention is separated from a transmitter 11 provided on the gun body side and from the gun body. It is comprised from the receiving part 21 arrange | positioned in a position.

The transmission unit 11 includes a vibration detection sensor 12 that detects vibration generated in the gun body by a firing operation. The vibration detection sensor 12 in this example uses a piezoelectric element as an element that converts vibration into an electrical signal. Yes. Reference numeral 13 denotes a sensor amplifier that amplifies the electric signal, 14 denotes a microcomputer, 15 denotes a transmission module, and 16 denotes an antenna.

In the embodiment, a buzzer piezoelectric element is used as the vibration detection sensor 12. As a piezoelectric element, a so-called piezoelectric element is used as a sensor for obtaining a voltage from a displacement. However, this element is easily available and inexpensive, and has sufficient performance as a target vibration detection sensor. The sensor amplifier 13 also serves as a frequency filter, and mainly amplifies high-frequency vibration generated by a gun mechanism in accordance with a launch operation. In the example of FIG. 1, a high-pass filter is used.

The amplified signal is input to a comparator, and the comparator built in the microcomputer 14 is used. At this time, in the present invention, sensitivity adjustment is performed by changing the set value of the reference voltage. This can be configured as follows.
Sensitivity setting: (H) High reference voltage <Sensitivity setting: (M) Standard time reference voltage,
But to avoid malfunction, another condition,
Sensitivity setting: (L) Low reference voltage,
Is also added.
In the high sensitivity (H) setting, malfunctions are likely to occur as much as the sensitivity is high, but in the low sensitivity (L) settings, malfunctions are also suppressed. Moreover, in the setting of low sensitivity (L), the duration of vibration is also added to the condition. This is because when a simulated gun is accompanied by a blowback operation, vibrations with a long duration are observed, so it is clearly distinguished from short vibrations caused by factors other than blowback, and attempts to eliminate malfunctions as much as possible. .

The vibration detection sensor 12 preferably has a configuration in which the vibration detection sensor 12 is supported substantially at right angles to the bullet firing direction F in order to match the directionality of sensitivity with the direction of vibration at the time of bullet firing (see FIG. 5). However, the vibration detection sensor 12 of the example of FIG. 6 that is supported substantially in parallel with the bullet firing direction F is also effective. The reason is that there are guns that are easy to detect vibration and guns that are difficult to detect. In the case of a gun that is easy to detect vibration, the sensor 12 is arranged in parallel with the bullet firing direction F and is difficult to detect. This is because in the case of a gun, the sensor 12 can be dealt with by arranging it at right angles to the bullet firing direction F. A support 17 is used to support the vibration detection sensor 12. The illustrated support body 17 is formed of a substantially U-shaped member, and the edge of the vibration detection sensor 12 is fixed at one point. However, a two-point support and a three-point support are also possible. That is, since the way of fixing is also related to the detection of vibration, the design can be changed according to the gun regardless of the illustrated example. That is, the sensor 12 can be arranged at an arbitrary angle within a range perpendicular to or parallel to the bullet firing direction F.

Also, a sensor amplifier 13 'with a frequency filter is used as the sensor amplifier in the present invention. As the sensor amplifier 13 ′, a sensor amplifier that amplifies vibrations of 70 to 80 Hz is used, making it easy to distinguish between the gun body and the firing operation, and is suitable for preventing malfunctions. is there. The degree of amplification by the sensor amplifier 13 'can be adjusted by adjusting the volume and the sensitivity can be adjusted.

With respect to the above reference voltage, the setting method can be improved and the sensitivity can be dynamically switched as follows.
1) Stand by with high sensitivity.
2) When the first launch operation is detected, switch to low sensitivity.
3) Stand by with low sensitivity.
4) Return to step 3) when another launch operation is detected.
5) Return to 1) if the launch operation is not performed for a certain period of time.

FIG. 2 shows a circuit diagram as a specific example of FIG. In FIG. 2, reference numeral 18 denotes a sensitivity changeover switch. The sensitivity changeover switch 18 is used to switch the sensitivity between the high sensitivity and the low sensitivity. In order to show the operating state of the device 10 according to the invention, it is also possible to incorporate an operating monitor consisting of LEDs, for example.

On the other hand, the receiving unit 21 includes an antenna 22 that receives the weak radio wave transmitted from the transmission unit 11, and a control circuit 24 for reading out sound effect data stored in the storage device 23 from the received weak radio wave, A sound effect generator 26 for enabling the read data to be heard via the amplifier 25 is provided (see FIG. 1). As the storage device 23, the one built in the microcomputer 27 is used. The microcomputer 27 is also used as the control circuit 24. Reference numeral 19 denotes a receiving module, and 49 denotes a low-pass filter.

In the circuit diagram of FIG. 2, which is a specific example of FIG. 1, reference numeral 28 denotes a sound effect changeover switch. The sound effect changeover switch 28 is used to call a target sound effect from among a plurality of types of sound effect data recorded. Also, an operational monitor comprising, for example, LEDs can be incorporated to indicate the operational status of the device 10 of the present invention.

The transmitter 11 of the sound effect generator 10 in the simulated gun of the present invention is equipped on the gun body 30 side according to the modes shown in FIGS. In FIG. 3, 29 is a laser sight, 31 is a foregrip, 32 is a tracer, 33 is a flashlight, and 34 is a sighting device. Each of these parts and members includes the sound effect generator 10 described above. The transmitter 11 can be incorporated. The transmitter 11 of the sound effect generator 10 of the present invention can of course be incorporated into a silencer mounted at the position of the tracer 32, and is easy to downsize. Therefore, most of the transmitter 11 is not shown in FIG. It can be incorporated into parts and members.

The grip 31 is attached to an attachment base 35 called a picatinny rail provided in the gun body 30 by an engaging portion 36, and the position of the grip 31 can be adjusted (see FIG. 4). However, the transmission unit 11 of the sound effect generator 10 of the present invention is not limited to the incorporation into these external equipments, but can naturally be incorporated into the gun body 30.

Furthermore, an example of incorporating the transmission unit 11 of the sound effect generator 10 of the present invention is shown. FIG. 5 shows an example of incorporation into the foregrip 31. The vibration detection sensor 12 supported substantially at right angles to the bullet firing direction F is attached to the substrate together with the power battery 37, the on / off switch 38, and the sensitivity selection lever 39. FIG. 6 shows an example of incorporation into the tracer 32, and the same components are indicated by the same reference numerals. This example is different in that a larger battery 37 ′ is used and the vibration detection sensor 12 is supported substantially in parallel with the bullet firing direction F.

The receiver 21 is shown in the same box-shaped case in FIGS. 5 and 6. In each figure, 41 is an on / off switch, 42 is a power supply battery, 43 is a sound effect selector switch, 44 is a volume knob, 45 is a pilot lamp (acts as a kind of monitor), 46 is a jack, and sound effects are generated. A plug 46a of a headphone 47 which is one of the units 26 is inserted (see FIG. 8). Reference numeral 48 denotes a speaker, which is connected to the receiver 21 in a wired manner as one of the sound effect generators 26.

In the sound effect generating apparatus 10 of the present invention configured as described above, a firing operation is performed by a person P using a simulated gun pulling a trigger, thereby generating vibration in the gun body 30, and the vibration is detected by vibration detection. Detected by the sensor 12, the transmitter 11 is activated. The detected vibration is converted into an electric signal and is first amplified by the sensor amplifier 13. In the case of amplification by the sensor amplifier 13 in FIG. 1, the operation sound generated by the mechanism of the gun body 30 in accordance with the launching operation is intensively amplified, and the amplified signal is input to a comparator built in the microcomputer 14. If the signal voltage exceeds the reference voltage, it is determined that the launch operation has been performed, and a transmission sequence of a radio signal indicating ON is started, whereby a weak radio wave is transmitted from the transmission module 15 as an ON signal.

Further, in the case of amplification by the sensor amplifier 13 'in FIG. 1, since the sensor amplifier 13' also serves as a frequency filter, the difference between the time of touching the simulated gun and the time of firing is set as the most easily distinguishable frequency. This will amplify the vibration of 70 to 80 Hz. A weak radio wave is transmitted from the transmission module 15 as an ON signal through the detection and amplification of vibration as described above. In addition, because of the characteristics of the radio, signal loss may occur depending on the environment, so the same signal is transmitted twice to ensure signal transmission, and if it can be received even once, a sound effect will be heard. It is provided to be generated once.

The weak radio wave transmitted from the transmitter 11 is received by the receiver 21, and the sound effect selected by the sound effect selector switch 43 is read from the sound effect data stored in the storage device 23. The read data can be listened to by the control circuit 24 via the amplifier 25, and can be heard from the headphones 47 or the speaker 48 of the sound effect generator 26 as an emission sound full of realism.

In a survival game, shooting competition, or the like, when playing while listening to the sound of launching, in the present invention, the receiving unit 21 arranged at a position distant from the gun body 30 is remarkably miniaturized, and the headphones 47 are used as a sound effect generating unit. Can be used. For this reason, the receiver is housed in the player's pocket, pouch, etc., and the headphones 47 are mounted on the head. In addition, as to whether to use the headphones 47 or the speakers 48, the jack 46 can be inserted and removed depending on the situation, so that the effectiveness is further improved.

In the above embodiment, an example is shown in which the receiver 21 and the sound effect generator 26 are connected by a wired method, but the wireless method is not excluded. The simulated gun used in the present invention is a manual gun having a structure in which a piston is manually driven by pulling a trigger and compressed air is injected, a so-called electric gun that electrically drives the piston, This means a gun that does not aim to kill a gun intended for killing, that is, a real gun, including a gas gun that uses compressed gas.
