Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a game device.

[0002]

2. Description of the Related Art Conventionally, in a shooting game device or the like, a game screen in which the game space is viewed from a predetermined viewpoint position is displayed as an image, and the sound effects of various shooting events occurring in the game space (for example, the shooting sound of a bullet). , Hit sound, etc.) is output as a sound to enhance the reality of the game.

Further, in order to further enhance the reality of the game, a body sonic technique or the like is used so that the player sitting in the seat can experience the sound of bullet firing or hit sound as low frequency vibration. There are also things. As a result, the player can feel the event sound generated in the game space, for example, the sound of a missile hitting an enemy tank as a sensational vibration, and can enjoy a shooting game with a more powerful sound. Becomes

Assuming, for example, an event such as a missile fired from a player tank hitting an enemy tank, a conventional game device outputs event sound such as a hit sound from a speaker at the same time. By the low frequency component separated from this event audio signal,
It was configured to drive body sonics and generate sensible vibrations.

Further, in addition to sound or vibration, it may be possible for the player to experience the firing and explosion of bullets as wind.

However, in order to apply the wind to the player using the fan, a large circuit including a motor is required, and it is difficult for the fan to experience a gust of a blast because the reaction is slow.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a game device which allows a player to experience a quick reaction wind with a simple circuit.

[0008]

In order to achieve the above-mentioned object, the invention of claim 1 has a speaker, in a game device, for generating a sound wave in a diaphragm, and a hollow member to which the speaker is attached. The hollow member is characterized in that an input opening that is closed by the diaphragm and an output opening having a smaller diameter than the input opening are formed.

According to the present invention, when the speaker is driven,
The diaphragm that closes the input opening of the hollow member vibrates, and the sound wave generated by this vibration propagates through the air in the hollow member as a compression wave. Then, the compressed air in the dense state is discharged from the output opening. Moreover, since the output opening has a smaller diameter than the input opening closed by the diaphragm, the compressed air is further compressed and discharged, and at this time, wind is generated.

Since the speaker can be driven quickly, this wind can produce an effect such as a gust of a blast. In addition, since a speaker driving circuit is simple, a large circuit for driving a motor is not necessary.

According to a second aspect of the present invention, in the game apparatus according to the first aspect, the speaker is a bass woofer.

The reason why the woofer is used in this way is to adapt to the generation of a strong wind. To explain its action, since the sound wave is a compression wave, when compressed air in a dense state is discharged from the output opening and blows out wind, the low pressure air in the next sparse state pulls back the wind. Act on. Therefore, when the frequency is high (high sound), the wind is immediately pulled back, and the wind becomes weak. On the other hand, when the frequency is low (low tone), it takes a relatively long time to pull back the wind, and the wind becomes strong. And the sound with low frequency (bass)
The woofer is suitable for producing.

According to a third aspect of the present invention, in the game apparatus according to the first or second aspect, the hollow member is configured as a seat on which a player sits.

As described above, when the hollow member is formed as a sheet, the space is not wasted.

Particularly, as in the invention according to the fourth aspect, a preferable effect can be obtained by opening the small diameter opening toward the head of the player.

[0016]

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a preferred example of the game device according to the present embodiment. In this game device, a tank operated by a player P in a virtual three-dimensional game space
It is configured to battle with other tanks and play a three-dimensional shooting game. The player P sits on the seat 10 and operates the steering wheel 20, the accelerator 22, and a brake (not shown) to steer the tank on the display 24. That is, the player P can freely move back and forth, left and right in the play field set in the virtual three-dimensional game space by operating this tank.

In addition, as an attack item,
It is equipped with a cannon, and by operating a trigger button 26 provided on the handle 20, a cannon can be fired from the cannon.

Next, FIG. 2 is a view showing a state in which the cover is removed from the seat 10, and FIG. 3 is a sectional view taken along the line AA of FIG.

As shown in FIG. 3, the sheet 10 is formed to have a hollow inside. Then, as shown in FIG. 2, near the headrest of the seat 10,
A speaker 30 for audio output is provided on the right side of the drawing, and the BGM
It also outputs narration, as well as the sounds of various events that occur in the game space. This allows the player to visually and aurally enjoy the game by combining the game screen displayed on the display 24 and the sound output from the speaker 30.

An opening 12 is formed on the left side of the seat 10 near the headrest.
An L pipe 16 is attached to the inside of the so as to face upward to prevent dust from entering the inside.

The opening 12 is for blowing out the wind, and for that purpose, a woofer 40 is provided at the bottom of the seat 10. The woofer 40 is a large-diameter speaker suitable for reproducing low-pitched sound, that is, low-frequency sound waves,
It can output about 40W. And
When a low frequency signal is input, the diaphragm vibrates at a low frequency and produces a low tone.

The woofer 40 is attached to the opening 14 formed on the back surface of the bottom of the seat 10 to emit a sound toward the inside of the hollow of the seat 10. Specifically, the diaphragm of the woofer 40 is attached so as to cover the opening 14. The opening 14
Since the woofer 40 has a large diameter,
It is formed with a larger diameter.

Since the woofer 40 is attached in this manner, the sound wave is a compression wave propagating in the air. Therefore, the sound wave generated from the woofer 40 propagates as a compression wave in the hollow interior of the sheet 10 and becomes a dense state. The air expands outward from the opening 12, and wind is generated when the air expands.

Moreover, the opening 14 as the entrance of the sound wave
However, since it is larger than the opening 12 as the outlet of the sound wave, the dense portion of the compression wave has a higher density.

This operation will be described with reference to FIG. The figure shows a device in which a woofer 56 is attached to a large-diameter opening 52 of a conical pipe 50 so that sound is emitted toward the small-diameter opening 54. Then, when a signal is input to the woofer 56, a compression wave of air is generated by the vibration of the diaphragm, and the compression wave is transmitted to the opening 54. Here, since the pipe 50 has a conical shape and the diameter becomes smaller as the compressional wave advances, the dense part of the compressional wave is gradually further compressed.

Similarly to this, the sheet 10 shown in FIG.
Even in the hollow inside of the above, the dense portion of the compression wave becomes higher in density when passing through the opening 12 than the density at the time when the woofer 40 generated. Then, the compressed air having a high density expands from the opening 12 to generate wind. As shown in FIG. 1, the wind hits the player P's neck and head.

Further, in the present embodiment, the woofer 40
Sound waves as compression waves reproduced by
It is preferably about z. According to the experiments conducted by the inventors of the present application, a sound wave having a frequency of 5 Hz felt as an intermittent wind, and a sound wave having a frequency of 40 Hz felt as a continuous wind. Furthermore, the diameter of the L pipe 16 is 25
When it was set to mm, the strongest wind could be experienced.

As described above, when the wind is sent out from the opening 12 toward the player P, the wind generated by the blast and the like is imaged, and the fun of the game is increased. What's more, a simple circuit is enough to send out this wind.

According to the above embodiment, the woofer 4
Although 0 is used only as a means for sending out the wind, the woofer 40 may vibrate the seat 10 or generate a sound effect.

Further, the woofer 40 can be provided in a place other than the bottom portion of the seat 10, for example, inside the box portion where the handle 20 is attached or in other places. At that time, the opening 12 may be provided at an appropriate position toward the player so that the player can easily feel the wind. At this time, the compression wave may be guided from the woofer 40 to the opening 12 by a pipe or the like.
