2. Description of the Related Art Conventionally, an electric / mechanical vibration converter that vibrates with a voice signal of music has been manufactured so that the body can feel music in addition to hearing it from the ear. By operating with a voice signal, you can experience a comfortable vibration. For example, attach an electric / mechanical vibration converter to a chair in the listening room,
With the music from your ears, you can feel the vibration of the chair due to the music signal, and try to boost the sense of presence. In particular, it is even more effective if the low-pitched sound such as onomatopoeia or impact sound is expressed by vibration. Also, in an aerobics classroom, when the user's body is vibrating in a dance song, it is not possible to grasp the song from the ear. The vibration is sensational and the effect is enhanced.

An electric / mechanical vibration converter will be described with reference to FIGS. 8 to 11. The electric / mechanical vibration converter 1 used here has a concave case 2 and a thin plate 3
The case 2 is covered with a mounting hole 2a and the lead wire 4 is connected thereto. The lead wire 4 is connected to a tubular coil 5 fixed to the center of the plate 3. A plate-shaped damper 6 is mounted on the inner circumference of the case 2, and an annular yoke 7 and an annular magnet 8 are suspended. That is, the annular yoke 7 is attached to one surface of the annular magnet 8 and the yoke 9 having a convex cross section is attached to the other surface of the magnet 8. The convex portion 9a of the yoke 9 is inserted into the inner hole of the magnet 8 to form an annular gap. The coil 5 is inserted in the annular gap.

When a signal current flows through the coil 5, a magnetic field is generated, and the yokes 7 and 9 and the magnet 8 repel the magnetic field. Therefore, if the electric / mechanical vibration converter 1 is in a floating state in the air, the position of the case 2 side changes due to the vibration around the magnet 8 side having a large mass. As for the relative vibration, even if the case 2 is attached to the vibrating body, the amplitude shape on the magnet 8 side is almost the same,
It is possible to efficiently generate vibration that follows the signal current.

By the way, when the electromechanical vibration converter is attached to the chair in the listening room,
Since the method of embedding inside the chair is adopted, a dedicated chair will be manufactured. Therefore, it is expensive to arrange the number of chairs, and it is not easy to set up a listening room. On the other hand, nowadays, portable cassette decks make it easy to play back tapes and listen to music. Therefore, rather than sitting still in the above chair, there is a case where the user listens to music with the earphone as BGM while doing something. In this case, there is a problem in that the user does not sit in a dedicated chair, but no sensation vibration is obtained, and the sense of presence is halved.

Also in the aerobics classroom, each person can listen to different music and perform aerobics exercise in accordance with the music. However, in this case, it is not suitable to use a floor-mounted electromechanical vibration converter. In addition, wearing a large-scale vibration device on the body deprives the body of freedom.

As shown in FIG. 12, there is a small electric / mechanical vibration converter 1 housed in a bag 10 so that it can be carried anywhere. It is used to get a sensory vibration by being sandwiched between the body and the chair, and there is a trouble that the user has to positively press the bag against the body. In addition, this limits the means for listening to music.

In addition, when listening to music outdoors, a portable cassette deck is often used. However, in a place where vibration noise is great, such as in a train, it is difficult to hear even when using an earphone. There is a risk of noise due to the situation.

According to the present invention, a simple wearable sensation for converting a sound in the audible range into an electric sound signal and inputting the sound signal so that each person can easily experience the vibration caused by the sound signal. It is an object to provide a vibration device.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention generates a vibration in a bag which is brought into contact with a body, which is substantially in accordance with a waveform of an audio signal in which an audio signal in an audible range is electrically converted. The electric / mechanical vibration converter is built in along the surface of the bag facing the body with the vibration surface of the electric / mechanical vibration converter, and the electric / mechanical vibration converter is provided with an audio signal input end. It is characterized by the fact that a belt is attached to the bag so that it is almost in close contact with the body.

In the above bag, when the bag member sandwiched between the electric / mechanical vibration converter and the body is made of a hard material such as plastic or metal, the electric / mechanical vibration converter and the bag member are Fix it so that chattering noise due to vibration does not occur between them. When using soft leather, cloth, or a soft material such as sponge, use a thin material to suppress vibration attenuation.

The belt to be attached to the bag is characterized in that the length of the simple wearable type body sensation vibrating device can be adjusted to the arm portion, abdomen portion, leg portion or the like. Further, this belt may be combined with a shoulder belt whose length is adjustable, or two similar belts may be combined.

[0013]

Since the present invention is configured as described above, since the bag is pressed against the body and fastened tightly with the belt, the simple wearable type body vibration device can be worn over clothes. Therefore, the vibration of the electric / mechanical vibration converter is directly transmitted to the body without being affected by the movement and the behavior of the body. Further, conversely, the belt position can be changed and worn so as not to hinder the movement and behavior of the body. When listening to music, you can enjoy sitting on your favorite chair regardless of your physical posture.

Further, when it is worn on the upper arm, there is little sensation vibration to the body such as the chest and the stimulus to the brain is transmitted directly from the shoulders, so that the impact of the movement of the legs such as during walking does not interfere. Further, the shoulder belt can be stably worn on the waist, and in this case, since the vibration stimulus is transmitted to a wide area of the chest and the back, a sensible vibration can be obtained almost over the whole body. Further, when the user wears the thigh of the foot, when he or she is standing, it is possible to experience the vibration in preference to other vibrations at the feet.

[0015]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a simple wearing type sensible vibration device
The reference numeral 11 is a bag 13 that is closely attached to the body 12 and has the electric / mechanical vibration converter 1 built therein. The electric / mechanical vibration converter 1 is fixed via a seat 14, and a cushion 15 is provided in another gap. Is filled. The lead wire 4 is drawn out from the bag 13 and connected to the output of the amplifier. Also,
A belt 17 is provided by mounting brackets 16 attached to both sides of the bag 13.

When the electric / mechanical vibration converter 1 is a hard plastic bag 13, it is easy to fix it by shifting it to one side. By interposing the sheet 14, chattering noise during vibration is prevented. There is. Further, the cushion 15 is configured to damp the vibration to the opposite side. In addition, by composing the bag 13 with cloth, soft leather or similar soft material, it fits your body when worn, and
The generated vibration can be transmitted to the outside through these.

By the way, in order to vibrate the electric / mechanical vibration converter 1, an amplifier, a sound source and a battery are required, and these are housed in another bag and attached to the waist with a belt. Further, by fixing the bag 13 on the flat surface of the belt 17, manufacturing can be facilitated (see FIG. 2).

In the simple wearing type sensible vibration device 11, the belt 17 is attached to the bag 13, and the length of the belt 17 can be adjusted to apply the bag 13 to each part of the body. As shown in FIG. 3, when the bag 13 is closely fixed to the upper arm of the body 12,
Although the lead wire 4 of the electric / mechanical vibration converter 1 is passed through the shoulder and then turned around the waist, the lead wire 4 can be removed and the antenna 18 can be attached to make it cordless. In this case, the bag
The small receiver amplifier and battery are stored in 13. In addition, light (infrared rays or the like) may be used as a medium as the transmission means.
The signal source can also be self-sufficient by mounting a portable cassette deck.

When a voice signal such as music or impact sound is input to the electric / mechanical vibration converter 1 built in the bag 13, vibration is felt in the upper arm. Also, vibration stimulation becomes partial, and most of the stimulation is transmitted from the shoulder to the brain,
It is effective when you are moving your legs, such as while walking,
You can also change the degree of sensation you can experience by focusing on your arms. In addition, the upper arm is tightened with the belt 17 and the body is hardly restrained.The body can be moved and acted freely, and the user can feel the vibration, and depending on the posture of the body such as when listening to music.

A belt 11 has a belt 17 attached to a lower portion of a bag 13, an insertion band 20 provided on an upper portion, and a waist belt 21 passed through the insertion band 20. As shown in FIG. 7, when the bag 13 is attached to the thigh, the stimulus due to the vibration is partial, but when standing on the ground, the stimulus of the sensory vibration from the bag 13 causes the vibration from the ground. Stimulation can also be reduced, for example, when listening to music on a cassette tape on a train, if the simple wearing type sensible vibration device 11 is attached to the thigh, vibration stimulus due to running of the train is reduced, and other sounds You can easily listen to music without being disturbed.

In the above-described simple wearing type sensible vibration device 11, as the audio signal input to the electric / mechanical vibration converter 1, an audio signal obtained by processing the audio with a low-pass filter or a single frequency in the low frequency range ( 50-350 Hz)
There is a voice signal in which the amplitude height of the voice is modulated by the envelope signal which has been communicated. Since the former does not have high-frequency vibration, the vibration stimulus can be felt more sensibly. In the latter case, the continuous vibration can be experienced even if the low-pitched sound is intermittently missing when the sound is converted into an electric signal.

From the above, when using for listening to music, a dedicated vibrating chair is not required, and the user can enjoy in a light posture simply by mounting the bag on his body. Further, even in an aerobics class, no large equipment for sensation vibration is required, and each person can easily exercise according to different songs.

As described above, since the simple wearable type sensible vibration device 11 can be easily attached to a part of the human body, it can be widely used in daily life. For example, when the head is not clean, a simple wearing type sensible vibration device 11 is attached to the head so that the user can feel the loose vibration of the musical deep bass and feel the vibration while feeling the vibration. Use as a purpose. In addition, when practicing playing a musical instrument in a general home, the volume of sound can be lowered by experiencing the sound of the performance by vibrating, so that the sound can be easily used like a headphone.

When a sport is performed, a signal for input is extracted from the dynamic music, and the simple wearing type sensible vibration device 11 mounted on the body is operated by this signal,
When acting as an accompaniment, it is possible to maintain the concentration more than the accompaniment of the sound from the speaker. It is also possible to use it to transmit the timing of breathing by vibration. In addition, by making the simple wearing type sensible vibration device 11 waterproof, it can be carried in water. Especially in indoor pools, the sound of the speaker echoes and becomes unclear,
By vibrating in the water, information such as the rhythm of music can be clearly transmitted.
