Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a vibrating floor panel vibrated by an electro-mechanical vibration converter.

(Prior Art) Conventionally, chairs and cushions equipped with electro-mechanical vibration transducers have been made to vibrate in response to reproduced sound using acoustic electrical signals from a stereo system (sound reproduction device). There is.
With such a system, you can hear the reproduced sound with your ears and feel it directly with your body,
It is possible to reproduce sound with a sense of realism.

However, in such systems, the sound is usually reproduced while sitting on a chair or cushion, so the sound vibrations cannot be felt through the soles of the feet. For this reason, even if the above-mentioned system is used, it has not been possible to reproduce the sounds that actually occur in the natural world as if you were actually there, for reasons that will be explained later.

That is, sounds generated in the natural world may be accompanied by vibrations of the earth, buildings, etc. For example, noise is generated when a tree is felled or on a station platform. When a tree is cut down, the ground also vibrates with the impact sound that is generated when the tree falls. Further, on a station platform, etc., the running vibrations of the train are transmitted to the platform, causing the platform to vibrate, along with the running noise caused by the train entering the platform.

The vibrations of the earth and buildings that occur when such sounds are generated are felt through the soles of the feet, so even if the cushions and chairs mentioned above transmit the vibrations of the earth and buildings to areas other than the soles of the feet. , it was impossible to feel this vibration as if you were in the place where it was occurring. As a result, as mentioned above, it is impossible to reproduce the sounds that actually occur in nature as if you were actually there.

In order to solve this problem, an electric-mechanical vibration transducer is attached to the underside of the floor of a building, and by vibrating the entire floor, it is possible to reproduce the vibrations as if you were in that location. There is.

As a device capable of reproducing such realistic stereo sound, Japanese Patent Application Laid-Open No. 1973-
There is one disclosed in Publication No. 90102. This device has an exchanger such as a vibrator attached to the underside of the floor so that the vibrations from the vibrator are transmitted to the soles of the feet through the floor.

(Problem to be solved by the invention) However, when installing an electro-mechanical vibration transducer on the underside of the floor of a building that has already been constructed, the installation work must be done in a narrow space. There were times when work and maintenance inspections were difficult.

Moreover, since the floor is directly vibrated, the entire building vibrates and the sound equipment also vibrates, which is not preferable for sound reproduction because it causes problems such as howling, especially when a record player is used.

Various installation methods have been considered to prevent the transmission of vibrations to the building itself, but it has been difficult to prevent the transmission of vibrations.

In addition, some buildings that are actually constructed have concrete floors that are difficult to vibrate, and it is impossible to vibrate the floor in a desirable manner even if the above-mentioned electro-mechanical vibration converter is installed on such concrete floors. There were also some problems.

The present invention has been made with the aim of solving these problems.

(Means for Solving the Problems) In order to solve the above problems, the vibrating floor panel of the present invention includes a cushion plate on the underside of a small diaphragm as a support member for supporting the diaphragm away from the floor. , a small hole is formed in the cushion plate to expose a part of the diaphragm, and an electro-mechanical vibration converter is attached to the bottom surface of the diaphragm in the small hole. , the peripheral edge of the diaphragm is configured to protrude from the peripheral edge of the cushion plate to form a connecting flange. More specifically, the cushion plate as a support member is a leg member attached to several locations on the lower surface of the periphery of the diaphragm.

(Function) In the vibrating floor panel configured in this way, when a low frequency acoustic signal is input to the electro-mechanical vibration converter attached to the bottom surface of the diaphragm, the electro-mechanical converter is regenerated by this. It vibrates in sync with the sound being played. This vibration is further transmitted to the diaphragm, so the diaphragm also vibrates in synchronization with the reproduced sound.

Since this diaphragm is supported away from the floor of the building by a support member attached to its lower surface, vibrations are hardly transmitted to the building itself.

Therefore, when you step on the diaphragm of such a vibrating floor panel, you can directly feel the low-frequency acoustic vibrations synchronized with the sound from the speakers through the soles of your feet, making you feel like you are actually in the place where the sound is coming from. conditions can be better reproduced.

(Embodiment) Next, an embodiment of the present invention will be described based on FIGS. 1 to 5. FIG. 1 shows a state in which a vibrating floor panel 2 is connected to a stereo system (sound reproduction device) 1. As shown in FIG.

In FIG. 1, a stereo system 1 includes an amplifier 3, a tape deck 4, a tuner 5, and a record player 6 connected to the input terminal of the amplifier 3.
, a speaker 7 connected to the output terminal of the amplifier 3, a headphone 8, etc.

The vibrating floor panel 2 connected to the stereo system 1 has a diaphragm 9 and a cushion plate 10 attached to the lower surface of the diaphragm 9, as shown in FIGS. 2 and 3. The cushion plate 10 consists of a first elastic layer 10a that is relatively hard and a second elastic layer 10b that is sufficiently softer than the first elastic layer 10a and has more elasticity. In this embodiment, the first elastic layer 10a is made of foamed polyethylene or the like, and the second elastic layer 10b is made of foamed polyurethane or the like. Note that the cushion plate 10 has a first elastic layer 10a attached to the diaphragm 9.

The cushion plate 10 and the diaphragm 9 are formed into a square shape. Furthermore, the diaphragm 9 is formed to be slightly larger than the cushion plate 10, and the peripheral edge of the diaphragm 9 protrudes from the peripheral edge of the cushion plate 10. This peripheral protrusion is the diaphragm 9
This serves as a flange 9a for connection.

Further, approximately in the center of the cushion plate 10, there are three holes 11, 1, which expose the lower surface of the cushion plate.
2 and 13 are drilled. An electro-mechanical vibration converter 14 inserted into the holes 11, 12, 13 is fixed to the diaphragm 9.

Case body 1 of this electro-mechanical vibration converter 14
5 is formed into a cylindrical shape. As shown in FIGS. 4 and 5, an upper lid 16 and a lower lid 17 are attached to the upper and lower openings of the case body 15. As shown in FIGS.
The inner peripheral surface of the case body 15 is provided with protrusions (not shown) at equal pitches in the circumferential direction. The damper 18 is formed into a flexible ring plate shape from an elastic material such as metal or synthetic resin. The damper 18 can therefore flex between the supporting projections (not shown).

Inside this damper 18, a ring 19 having a smaller diameter is arranged concentrically. This ring 19
is supported by the damper 18 at the center between the not-illustrated projections mentioned above. Inside this ring 19,
A cup-shaped yoke 20 that opens upward is fitted and fixed. A cylindrical permanent magnet 21 is fixed concentrically within the yoke 20. A cylindrical gap 22 is formed between the cylindrical portion of the yoke 20 and the permanent magnet 21. A disk-shaped pole piece 23 is fixed to the upper part of the permanent magnet 21. This pole piece 23, yoke 20, and permanent magnet 21
A magnetic circuit is constructed between the two.

A cylindrical coil frame 24 inserted into the cavity 22 is fixed to the upper lid 16. A coil 25 is wound around the circumferential surface of the coil frame 24 so as to be positioned within the gap 22. In FIG. 2, 26 and 27 are terminals connected to the coil 25. This terminal 26,2
By connecting the output terminals (not shown) of the amplifier 3 shown in FIG. 1 to 7 with the cords 28 and 29 via the amplifier 30 with a built-in low frequency acoustic signal passing filter, the vibrating floor panel 2 can be constructed as described above. so that it is connected to a stereo system.

Next, the operation of the vibrating floor panel 2 having such a configuration will be explained.

When a sound signal from a tape deck 4, tuner 5, record player 6, etc. is amplified by an amplifier 3 and outputted from the amplifier 3, the sound is reproduced by a speaker 7 or a headphone 8.

At the same time, the acoustic signal output from the amplifier 3 is input to the amplifier 30 via the cord 28. This amplifier 30 extracts a low frequency acoustic signal from the input acoustic signal, amplifies it, and outputs it.
This output low frequency acoustic signal is input to the coil 25 of the electro-mechanical vibration converter 14 via the cord 29. As a result, a magnetic force whose magnitude changes is generated in the coil 25.

A magnetic interference effect between a change in the magnetic force generated from this coil 25 and the magnetic force of the permanent magnet 21,
And, due to the spring action of the damper 18, the yoke 2
0. The permanent magnet 21 and the ball piece 23 reciprocate together between the upper cover 16 and the lower cover 17. This vibration is transmitted to the diaphragm 9 via the case body 15 and the upper lid 16. As a result, the diaphragm 9 vibrates due to the low frequency acoustic signal and the elasticity of the cushion 10. The vibration of the diaphragm 9 is synchronized with the sound reproduced from the speaker 7 and the head hose 8.

Therefore, by riding on the diaphragm 9 of such a vibrating floor panel 2 and reproducing sound while vibrating the diaphragm 9 as described above, low frequency sound synchronized with the sound from the speakers 7 can be produced. Since you can feel the vibrations directly from the soles of your feet, you can recreate the feeling of being in the place where the sound is actually coming from.

By connecting a plurality of such vibrating floor panels 2 using the connecting members 31 shown in FIGS. 6 and 7 as shown in FIG. 8, one large vibrating floor 32 can be constructed.
You can also do this.

In FIG. 6 and FIG. 7, the connecting member 31 has two elongated
It consists of a hexagonal connecting plate 33 having sides, and a cushion plate 34 of the same shape attached to the back side of the connecting plate 33. This connecting plate 33 is formed from a plywood board or the like, and the cushion plate 34 is formed from a first elastic layer 3 made of relatively hard foamed polyethylene.
4a and a soft second elastic layer 34b made of polyurethane foam. This connecting member 3
The thickness of 1 is the cushion plate 10 of the vibrating floor panel 2.
The cushion plate 34 of the connecting member 31 has a groove 3 in the center of the cushion plate 34 for inserting the cord.
5 is formed.

Such a connecting member 33 is disposed below the flanges 9a, 9a formed when the vibrating floor panels 2, 2 are arranged adjacently, as shown in FIGS. 8 and 9. Then, the flanges 9a, 9a and the connecting plate 33 are integrally connected with nails 36, 36. In this way, by connecting a plurality of vibrating floor panels 2, a vibrating floor with a large area is formed as described above.

This vibrating floor connects a plurality of vibrating floor panels 2 to form one vibrating floor with a large area, so it is easy to construct a vibrating floor that vibrates in the best condition as a whole, regardless of the size of the floor area. There is an effect that can be done.

Next, a second embodiment of the present invention will be described using FIGS. 10 and 11.
