Fake gun sound effect generating device

The present invention relates to a sound effect generating device for a fake gun, comprising: a transmitting portion mounted on the gun body side; and a receiving portion disposed at a position away from the gun body, and the transmitting portion is activated by the firing operation on the gun body side, The receiving part emits a sound.

So-called electric guns or air guns, or model guns, have surpassed the field of simple toys and are accepted by society. For example, some of the applicant's products are used by government agencies headed by the Ministry of National Defense, and the Ministry of National Defense is used for close combat training. This gun is called a fake gun relative to a real gun. Unfortunately, the sound of the launch is very different from that of the real gun. There is a clear difference.

Of course, it has been proposed to issue fake guns that emit sounds, but these guns are assembled inside a small loudspeaker, producing a shocking sound, and the problem is that it is not applicable except for large guns with assembly space. In view of this, the invention of Japanese Laid-Open Patent Publication No. Hei 6-66497 discloses a device which selectively generates one of the shooting sounds from among a plurality of shooting sounds. The invention does not assemble a sounding device or a loudspeaker inside the gun, and does not interfere with the shape of the gun, and is not restricted by the use of a small loudspeaker. However, the game gun that is mounted on the control box by using the flexible tube does not take into account the carrying of the gun at the beginning, and it is difficult to apply the fake gun.

In addition, the Japanese New Registration No. 3057385 is an idea that the bullet output of the bullet inside the toy gun is outputted by the FM wave, and the approximate large loudspeaker is placed. The radio wave transmitted by the FM is received by the FM stereo receiver, and the audio equalizer is corrected by the graphic equalizer set by the receiver, so that the sound of the shot becomes more realistic. Therefore, although a large volume can occur, since the output of the sound chip of the bullet emission sound is transmitted by the FM wave, the receiving part mixes the noise and mixes the noise, thereby reducing the sound quality, which is a disadvantage. Therefore, the sound quality problem is not solved, and even if a large volume can occur, the sound effect of the target is not achieved.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a sound effect generating device for a fake gun which can be heard with a shocking sound equivalent to a real shot by a transmitting operation, and is highly creative. Another object of the present invention is to use a small receiver and a headset to hear a sound that is full of presence in a game or a shooting game.

In order to solve the above problems, the present invention provides a sound effect generating device for a fake gun, comprising a transmitting portion mounted on the gun body side, and a receiving portion disposed at a position away from the gun body, and starting transmission by using a firing operation on the gun body side a sound is emitted from the receiving portion, wherein the transmitting portion is provided with a vibration sensor for detecting vibration of the gun body due to the transmitting operation, and a weak electric wave transmitting portion, and the vibration is detected according to the vibration sensor. a weak electric wave that emits a start signal, and the receiving part is provided with a control circuit that receives a weak electric wave emitted from the transmitting unit, reads the sound effect data memorized by the memory device, and the sound effect generating unit, and the above-mentioned read data can be Hear.

In the device of the present invention, the transmitter is used to activate the transmitter on the gun body side by the launching operation, and is arranged to move away from the receiver of the gun body. The launch operation is triggered by the launcher of the fake gun. The transmitting operation system is, for example, a trigger, etc., and is operated in various manners such as a switch. One of the features of the present invention is that it can detect the vibration of the launching operation due to any operation mode regardless of the transmitting operation.

Therefore, the above-mentioned transmitting unit can detect the vibration generated by the gun itself by using the vibration sensor. The vibration sensor should use a piezoelectric element to convert the vibration generated by the emission operation on the gun body side into a signal voltage. Therefore, the vibration sensor is configured such that the sensitivity of the vibration sensor matches the vibration of the bullet emission, and is preferably about a right angle or a substantially parallel range with respect to the bullet emission direction.

It is necessary to judge whether the vibration research is caused by the launching operation or the impact on the gun alone. In order to prevent malfunction, it is effective to distinguish the difference in the number of vibrations. When the vibration sensor is a piezoelectric element, a sensor amplifier should be provided to increase the amplitude of the signal voltage converted by the piezoelectric element, and the sensor amplifier should be used as a frequency filter for increasing the amplitude of the 70-80 Hz vibration. . This range of values is the easiest to distinguish between the frequency at which the fake gun is touched and the frequency at which it is emitted, as determined by the test.

The transmitting unit has a weak radio wave transmitting unit that bases the vibration detected by the vibration sensor to transmit the start signal to the weak electric wave. The use of weak electric waves as the start signal can significantly reduce the mixing of noise compared with, for example, FM radio transmission.

The receiving portion of the present invention is provided with a control circuit for receiving the weak electric wave transmitted from the transmitting portion, and reading the sound effect data stored by the memory device; and the sound effect generating portion, which can hear the read data by the amplifier. The sound effect generating unit may be configured to wear a receiver or a loudspeaker, and the headset may be connected to the receiving unit by wire connection. In addition, the memory device can record a variety of sound effects data.

Furthermore, the signaling unit of the present invention is composed of a vibration sensor and a weak radio wave transmitting unit, and can be assembled inside the gun body without requiring a necessary space. However, when mounted on the gun body side, it is not only referred to as the inside of the gun body, but may also be assembled in a component including a handle provided by the gun body, a muffler, a finder, a flash lamp, a laser sight, a crosshair, and the like.

The present invention has the above-described configuration and function, and with the transmitting operation, the shocking emission sound having the same real shot can be heard. In addition, the above-mentioned emission sound significantly reduces the mixing of noise, and it is possible to obtain a sound effect device that is full of a sense of sound and a highly creative fake gun. Further, according to the present invention, since the small-sized receiving unit and the head-mounted receiver can be used, the sound can be emitted and played in the game or the shooting competition. According to the present invention, the use of a fake gun is advantageous in that it is so full of the sound of the sense of presence, which is conducive to the tension of holding a real gun.

The invention will be described with reference to specific examples shown in the drawings. Fig. 1 shows an example of an electrical structure of a sound effect generating device 10 for a fake gun according to the present invention. The device 10 of the present invention includes a transmitting portion 11 mounted on the gun body side and a receiving portion 21 disposed at a position away from the gun body.

The transmitting unit 11 has a vibration sensor 12 that detects vibration generated by the firing operation on the gun body. In this example, the vibration sensor 12 uses a piezoelectric element, which converts the vibration into an element of an electrical signal. 13 is a sensor booster for amplifying the above electrical signals, 14 is a microcomputer, 15 is a transmitting module, and 16 is a transmitting antenna.

In the specific embodiment, the vibration sensor 12 is a piezoelectric element used in a buzzer. The piezoelectric element uses a sensor that uses a voltage to shift, but the element is easy and inexpensive, and has sufficient performance of the standard vibration sensor. The sensor amplifier 13 has a frequency filter. With the shooting operation, a high-frequency vibration of the gun mechanism is generated, and a high-frequency filter is used in the first example.

The amplified signal is input to the comparator, which is built into the microcomputer 14. At this time, the present invention performs sensitivity adjustment by changing the set value of the reference voltage. It can be constructed as follows.

Sensitivity setting: (H) high reference voltage <sensitivity setting; (M) standard reference voltage, but no error-free operation, and another condition is additional.

Sensitivity measurement: (L) low reference voltage.

The setting of the high sensitivity (H) is only likely to cause malfunction in a portion with high sensitivity, but the setting of low sensitivity (L) can suppress malfunction. Moreover, the vibration duration condition can be added to the setting of the low sensitivity (L). With the action of the recoil, the fake gun can observe the long-term vibration of the duration, and the short-term vibration caused by the cause other than the recoil force is clearly distinguished, and the malfunction is eliminated as much as possible.

The vibration sensor 12 is configured to support the vibration sensor 12 (see FIG. 5) because the sensitivity directivity coincides with the vibration direction of the bullet emission and is slightly perpendicular to the bullet emission direction F. However, the figure 6 illustrates that the vibration sensor 12 is also effective when it is supported in parallel with the bullet emission direction F. The reason is that there is a gun that is easy to detect, and there is also a gun that is difficult to detect. The gun that is easy to detect vibration is configured to arrange the sensor 12 in parallel with the bullet emission direction F, and the gun that is difficult to detect is the direction in which the sensor 12 and the bullet are emitted. F is configured at right angles and can correspond accordingly. The support of the vibration sensor 12 is the use of the support body 17. The illustrated support body 17 is composed of approximately U-shaped members, and the edge of the vibration sensor 12 is fixed at one point, but it is also supported by two points and three points. That is, the fixed method is related to the vibration detection, and is not limited to the illustrated example, and varies depending on the design of the gun. That is, the sensor 12 can be disposed at any angle within a range perpendicular to the bullet emission direction F at a right angle.

Further, the sensor amplifier of the present invention may be provided with a frequency filter 13'. The sensor amplifier 13 can be used for the key increase of the 70-80 Hz vibration; it is easy to distinguish the difference between the gun holding and the launching operation, and is suitable for preventing malfunction. The increase of the above-mentioned sensor amplifier 13 can be adjusted by the capacity or by the sensitivity.

Regarding the above reference voltage, the setting mode can be improved, and the dynamic sensitivity can be changed as follows:

1. Stand by for high sensitivity;

2. Inspect the initial launch operation and change to low sensitivity;

3. Stand by for low sensitivity;

4. Perceive the re-launch operation and return to 3.

5. To perform a certain time of launch operation, return to 1.

The specific example of Fig. 1 is shown in a circuit diagram in Fig. 2 . In Fig. 2, 18 denotes a sensitivity replacement switch. The sensitivity replacement switch 18 is used to change the sensitivity to become the above-described high sensitivity or low sensitivity. Further, in order to indicate the operation state of the device 10 of the present invention, for example, an operation monitor composed of an LED can be assembled.

On the other hand, the receiving unit 21 is configured to have an antenna 22 for receiving the weak electric wave transmitted by the transmitting unit 11; and the control circuit 24 for reading the sound effect data stored in the memory device 23 by the received weak electric wave; and the sound effect The generating unit 26 can hear the above-described read data via the amplifier 25 (see Fig. 1). The above memory device 23 is built in the microcomputer 27. The microcomputer 27 can also use the control circuit 24. Also, 19 is a receiver module and 49 is a low pass filter.

In the circuit diagram of Fig. 2 of the specific example of Fig. 1, reference numeral 28 denotes a sound effect replacement switch. The sound effect replacement switch 28 can change the desired effect of the exhalation from among the plurality of types of sound effects included. To indicate the operational state of the device 10 of the present invention, for example, an actuating monitor constructed of LEDs can be assembled.

The transmitting portion 11 of the fake gun sound effect generating device 10 of the present invention is attached to the gun body 30 side as shown in Figs. In Fig. 3, 29 is a laser sight, 31 is a front handle, 32 is a finder, 33 is a flash, and 34 is a crosshair. Any such component or component can assemble the transmitting portion of the sound effect generating device 10. 11. The transmitting portion 11 of the sound effect generating device 10 of the present invention can of course be assembled with a silencer positioned at the position of the finder 32, and can be easily miniaturized. The components shown in Fig. 3, which are not shown in any of the components and components, can be assembled.

The handle 31 is attached to the gun body 30. The mounting base 35 is mounted to the joint portion 36 and is adjustable in position (see Fig. 4). However, the transmitting portion 11 of the sound effect generating device 10 of the present invention is not limited to being assembled to other attached devices, and may of course be assembled to the gun body 30.

Furthermore, the signaling unit 11 of the sound effect generating apparatus 10 of the present invention is exemplified. Fig. 5 is an example of assembly of the front handle 31. The vibration sensor 12, which is supported at a right angle to the bullet emission direction F, is mounted on the substrate together with the power source battery 37, the opening and closing switch 38, and the sensitivity selection lever 39. Fig. 6 is an example of assembly of the finder 32, and the same members are denoted by the same reference numerals. This example differs in that a larger battery 37' is used, and the vibration sensor 12 is supported approximately parallel to the bullet emission direction F.

Regarding the receiver 21, the fifth and sixth figures are also shown as being housed in a box. 41 is an open/close switch, 42 is a power battery, 43 is a sound effect replacement switch, 44 is a volume button, 45 is an indicator light (a function of an inspector), 46 is a chuck, and can be inserted into the sound effect generating portion 26 One of the headphone receivers 46a (see Fig. 8) and 48 are loudspeakers, and one of the sound effect generating units 26 is connected to the receiver 21 in a wired manner.

In the sound effect generating device 10 of the present invention thus constituted, when the fake gun user P triggers the triggering operation, the gun body 30 vibrates, and the vibration sensor 12 detects the vibration, that is, the transmitting portion 11 is activated. The detected vibration is converted into an electrical signal, first amplified in the sensor booster 13. When the amplitude is increased by the sensor amplifier 13 shown in FIG. 1, the operation sound of the mechanism of the gun body 30 is increased with the launching operation, and the amplification signal is input to the comparator built in the microcomputer 14, and the signal voltage exceeds At the reference voltage, it can be judged that the transmitting operation is performed, which means that the start and start of the wireless signal transmission sequence, so that the weak electric wave becomes the start signal and is sent to the transmitting module.

Moreover, when the sensor booster 13' of FIG. 1 is increased, the sensor booster 13' also serves as a frequency filter. When the fake gun is touched, the setting can be different from the time of the transmission and the frequency is 70-80. The vibration of Hz is given a major increase. After the above vibration detection and amplification, the weak electric wave is the start signal, and is sent by the transmitting module 15. In addition, the wireless feature will mask the signal due to the environment. To ensure that the signal is transmitted, the same signal will be sent twice, and once it is received, a sound effect will occur.

The weak electric wave transmitted from the transmitting unit 11 is received by the receiving unit 21, that is, the sound effect data stored in the memory device 23 is selected by the sound effect replacing switch 43 to read the sound effect. The read data can be heard by the booster 25 by the control circuit 24, and the receiver 47 or the loudspeaker 48 is worn by the sound effect generating portion 26, and the sound of the sound that is full of the sense of presence can be heard.

In the game, the shooting game, and the like, when the player is not able to hear the sound, the present invention can significantly reduce the size of the receiving unit 21 disposed at the position away from the gun body 30, and the sound effect generating unit can use the headphone 47. . Since the receiver is placed in the player's pocket or hallway, and the head receiver 47 is placed on the head, it is rarely obstructive. Furthermore, whether or not the headphone 47 or the loudspeaker 48 is to be used, depending on the situation, the difference between the pullable chucks 46 can be selected to further improve the effectiveness.

The above embodiment shows an example in which the sound receiver 21 and the sound effect generating unit 26 are connected by wire, but the wireless method is not excluded. Moreover, the fake gun used in the present invention comprises a borrowing trigger, a manual firing, a pistol with a compressed air jet structure, an electric gun for electrically driving the piston, and an air gun using compressed air, that is, a real gun for killing purposes. Refers to a gun that has no purpose of killing.
