BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric / mechanical vibration converter for a bed, which can be easily attached to an existing bed to obtain a body acoustic vibration.

[0002]

2. Description of the Related Art A body acoustic sensor which receives a voice signal from an audio device or the like, converts it into a mechanical vibration, and receives this vibration with a sound from a speaker or headphones on the body has long been studied by the present inventors. Many patents and utility model rights have been acquired (Japanese Patent Publication No. 58-251).
7 gazette, Japanese Patent Publication No. 57-9272, Japanese Patent Publication No. 58-9640, Japanese Utility Model Publication No. 64-6622, Japanese Utility Model Publication No. 58-4316, etc.). In all of these publications, the electric / mechanical vibration converter is embedded in the human body mounting object or attached to the human body mounting object, and the vibration generated by the electric / mechanical vibration converter is passed through the human body mounting object. It is a structure given to the human body.

In any of the above inventions and devices,
When the mechanical vibration converter is embedded in or attached to a human body placing object, if the low frequency part of the audio signal is added to this, vibration that is synchronized with the sound from the speaker or headphones is given to the user through the human body placing object. Therefore, even at home or the like, it is possible to experience music with a sense of reality or to experience sound corresponding to images. The bed as an example

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 is a bed, and 2 is a mattress placed above the bed. On the outer periphery of the mattress 2,
A bracket 5 attached to a band (flat belt) 4 whose length can be adjusted by a buckle 3 is in contact. An upper portion of the bracket 5 is bent inward to form a key portion 6, and the key portion 6 is locked to a bead 7 formed on an edge portion of the mattress 2. Reference numeral 8 is an electric / mechanical vibration converter attached to the bracket 5.

As an example of the electric / mechanical vibration converter 8, an electrokinetic type will be described with reference to FIG. In FIG. 3, reference numeral 9 is a base plate having an outer periphery formed as a flange, and 10 is a cover. The cover 10 is fixed to the base plate 9 with bolts 11. Then, the following structure is housed in the case body formed by these, and the electromechanical vibration converter 8 is formed. Reference numeral 12 is a yoke having a T-shaped cross section as shown in the drawing. A ring-shaped magnet 13 is attached to the outer peripheral portion of the yoke 12, and a top plate 14 is provided on the outer side thereof, and these are supported by the above-described bolt 11 via a ring spring 15 as a damper. 16 is a spacer.

With the above structure, a magnetic gap 17 is formed between the inner periphery of the top plate 14 whose one surface is in contact with the magnet 13 and the protruding portion of the yoke 12, and the magnetic flux is concentrated. A coil 18 is provided inside the gap 17, and a voice current from an audio device (not shown) is given through a cord 19. 20 is a cushioning material. In this embodiment, the bracket 5 is fixed to the outside of the cover 10, but it may be integrally formed on the upper portion of the base plate 9.

As shown in FIG. 1, four electro-mechanical vibration converters 8 thus constructed are mounted side by side on a bracket 5, and the bracket 5 is mounted on a band 4. Therefore, the band 4 is appropriately loosened to position the electric / mechanical vibration converter 8 at the center of one side of the mattress 2 (of course, it can be set to a position other than the center if desired), and the key portion 6 of the bracket 5 is a bead of the mattress 2. Lock at 7.

In the coil 18 of the electric / mechanical vibration converter 8,
In this state, an audio signal that has been subjected to signal processing is supplied from an audio device (not shown). The four electro-mechanical vibration converters 8 may be connected to the audio equipment in series or in parallel, or in some cases serial-parallel connection. When this voice signal is applied to the coil 18, a magnetic force of the coil 18 and the magnet 13 causes a vibrating force on the coil 18 to integrally form the yoke 12, the magnet 13 and the top plate 14. Therefore, if a necessary mass is given to these, the integrated body of the base plate 9 to which the coil 18 is attached and the cover 10 vibrates.

As a result, the electric / mechanical vibration converter 8
Lateral vibration will be generated in the mattress 2 to which is attached (see FIGS. 4 and 5). This vibration is transmitted to the frame 22 (see FIG. 2) in which the spring 21 is attached inside the mattress because the key portion 6 of the bracket 5 is locked to the bead 7 of the mattress 2, and the entire mattress 2 is efficiently Will vibrate.

Due to this vibration, the user 23 lying on the upper side of the mattress 13 is given a vibration in the lateral width direction of the mattress 2 (see the arrow in FIG. 5). As described above, this vibration is synchronized with the sound generated from a speaker or the like (not shown), so that it is possible not only to hear music but also to experience it.

As described above, the bracket 5 is attached to the band 4. Therefore, by operating the buckle 3 and loosening the band 4, the bracket 5 can be fixed anywhere on the mattress 2. 6 to 8 show the bracket 5 thus positioned on the foot of the user 23 so that the vibration from the electromechanical vibration converter 8 is applied in the longitudinal direction of the mattress 2.

In the embodiment described above, four electric / mechanical vibration converters 8 are attached to the bracket 5, but the number may be more or less than four. The point is that it is only necessary to ensure the ability to give a necessary and sufficient level of vibration to the mattress 2.

Although an electric type having an internal structure as shown in FIG. 3 was used as the electric / mechanical vibration converter, the present invention is not limited to this, and the structure such as an electromagnetic type is used. It may be different. What is essential is that it is possible to generate a vibration corresponding to a music signal whose frequency and amplitude constantly change, such as a music signal.

A key portion 6 that is locked to the bead 7 of the mattress 2.
In the illustrated embodiment, is formed on the upper portion of the bracket 5, but the base of the electromechanical vibration converter 8 may be extended and formed on the extended portion without the bracket.

Since the present invention is an electric / mechanical vibration converter for a bed constructed as described above, a dedicated bed is used.
The key section can be placed at any position on the side of the existing bed without the need for a cord.
You can enjoy the vibrations of listening to music, etc. In addition, an electric / mechanical vibration converter for the bed
Since it is installed at a position removed from the plane , the sleeping comfort is not impaired. And can be installed in an existing bed
Because it is possible, it is possible to prepare for a cheap dormitory with many beds.
You can
