Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention converts a music signal or an emotional signal, which is an electric signal, into a mechanical vibration, and applies this vibration to a portion covered with hair of a body or a curved surface portion, that is, a head or the like. The present invention relates to a vibration device for head stimulation.

[0002]

2. Description of the Related Art Conventionally, it has been proposed to mount an electric / mechanical vibration converter on a chair, a mat or the like, which generates mechanical vibration along with an input signal waveform, and when watching a movie or music, see or hear. In addition, it is used to enhance low-frequency components such as rhythm in music and melody, and other low-frequency components into vibration to make the body feel it, and to enhance the realism of movies and music. Also, as will be described later, artificially create a certain repeating waveform group (emotional signal) that is configured with a regularity different from that of music, convert the emotional signal to make it feel vibrating, and use the image of this stimulus. There are things that try to help or control emotions. In this case, a plurality of kinds of emotion signals are prepared and selected according to the target atmosphere such as relaxation, tension, and concentration.

In the above-mentioned electromechanical vibration converter, a core having a large mass and a yoke are hung inside the case, and a coil for inserting the core is fixed to the inner wall of the case. When a music signal is applied to the coil, The core and yoke vibrate in the case. Therefore, the vibration of the core and the yoke vibrates without being affected by the external load, so that the electric / mechanical vibration converter can be easily attached to a chair, a mat or the like. In addition, the body part where the vibration comfortably resonates is checked in advance, and a plurality of electric / mechanical vibration converters are fixed to a chair, a mat, or the like at a position matching the body part to enjoy the vibration. In addition, it is possible to adjust the contact position by moving the body to adjust the stimulation.

[0004]

By the way, in the case of feeling comfort or widening an image, as described above, the vibration is felt from the feet and the back with the chair, the mat or the like.
However, in the case of directly transmitting vibration to the head to make it feel comfortable, the conventional device vibrates a flat surface or a flat plate, which cannot be dealt with by the unique condition of hair and round shape. It was Further, when the body is vibrated, it is common to feel the vibration by placing it on a vibrating human body placing object.

It is an object of the present invention to provide a head stimulating vibration device which surely transmits vibrations even when the curved surface of the body or hairs intervene.

[0006]

In order to achieve the above object, the present invention provides a plurality of protrusions on the vibrating surface of an electric / mechanical vibration converter including a coil and a core, and places them near the vibrating surface. A support portion is provided, and a music / emotional signal source is connected to the coil of the electric / mechanical vibration converter.

Further, in the above structure, a cushion is interposed at the base of the plurality of protrusions.

[0008]

The present invention is configured as described above, and when the support portion of the electromechanical vibration converter is a handle, the protrusion is brought into contact with the scalp from between the hairs by holding the handle and pressing it against the head. To do. On the other hand, a music signal or an emotional signal has a complicated waveform (information), unlike vibration by a single frequency whose amplitude does not change. When this music signal or emotional signal is passed through the coil, the core vibrates according to this signal in the case, and the vibration due to the music / emotional signal stimulates the scalp via the protrusions. In addition, since the protrusion vibrates with local strength, it also vibrates strongly the stimulation points (warm point, cold point, pain point, etc.) of the scalp. It should be noted that the plurality of protrusions have a shorter central portion so as to come into contact with a curved surface portion such as a head portion, so that vibration transmission is improved.

If the support portion is like a helmet, both hands are released, and if a vibration transmission device having a plurality of electric / mechanical vibration converters is attached to the head, it is suspended. The means reduces the weight burden on the head.

Further, in the case where the protrusion base has a cushion, by pressing a plurality of protrusions against the curved surface,
The elastic force acts at each location, and the plurality of protrusions are aligned and contact the surface of the curved surface.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1 to FIG. 3, a hairbrush type vibration device 1 includes a main body 2 and an electric / mechanical vibration converter 3.
Is incorporated so as to vibrate in the protruding direction of the plurality of protrusions 4 (arrow A), and a cord 6 connected to the electromechanical vibration converter 3 extends from the handle 5. The plurality of projections 4 are planted in a row-and-row arrangement with hair-like bundles of plant, plastic or the like in consideration of rigidity and touch feeling (the projections need only be regularly spaced). Further, a surface (boundary surface) connecting the tips of a plurality of protrusions of a general hairbrush is flat in the axial direction and has a convex shape in the direction orthogonal to the axis, but the vibrating device 1 of the embodiment has a boundary. The surface is flat or concave at the center.

In the electromechanical vibration converter 3, a core (and a yoke) 8 is suspended in a case 7 by a damper 9, and a coil 10 which inserts the core 8 is fixed to the case 7. A current flows through the coil 10. The magnetic interference acts between the core and the core 8 to extract the vibration output.

Signal sources connected to the electromechanical vibration converter 3 include a music signal source 11 and an emotional signal source 12 as shown in FIG. 12, and a switch 13 for selecting them. The musical signal source 11 and the emotional signal source 12 can be easily changed by cassettes, CDs, or the like. The inverter 14 attached to the switch 13 outputs a sum.

The music signal source 11 is a tape for recording a performance, C
For example, the low frequency part in the audible range is usually processed only for vibration, but here, since the ears are located near the vibration part, the weakened signals in the entire audible range are mixed. That is, the signal passed through the low-pass filter 15 and the attenuator 16 is put into the mixer circuit 17 and amplified by the amplifier 18 to generate a power signal.

The emotional signal source 12 is a signal that is artificially created. For example, as shown in the waveform of FIG. 13, different frequencies a and b (for example, 47 Hz and 35 Hz) are combined to change the strength along the attenuation curve. Put on. Further, the waveform pattern is a repeated signal. The signal that changes in this way is used to promote the image of the sound when the bell is struck. Alternatively, the intensity of vibration can be combined and repeated to create a feeling of tension. 14
The curves shown in Fig. 2 show the envelopes of different frequencies, and feel the melody by combining the attenuation curves of certain predetermined different frequencies a, b, c, ... (eg 49, 35, 44, 39 ,. Some are trying to make it happen. The frequency d is attenuated in two steps.

The hairbrush type vibrating device 1 constructed as described above holds the handle 5 and the projection 4 on the head 19 (see FIG. 1).
Refer to)). The protrusions 4 come into contact with the scalp through the hairs, and vibrations due to music / emotional signals stimulate the scalp via the protrusions 4. Further, since the vibrating device 1 is held by hand, the stimulation location can be easily changed, and the stimulation points distributed on the scalp can be appropriately stimulated by the vibration of the protrusion 4.

Up to now, when the vibrating surface of the electric / mechanical vibration converter is applied to the back, the palm, or the sole of the foot, the user applies a load, and the vibrating surface is intimately contacted and the vibration is transmitted. . In the present invention, by providing the protrusion 4,
Vibrations can be transmitted to places where surface contact is difficult. The head 19 has a problem that the hair is a hindrance, and it is difficult to transmit by plane vibration due to the round shape, but the hairbrush type solves these problems.

Therefore, it is easy to give vibration to the head, and when the nerves are relaxed or the blurred atmosphere is awakened from the comfort of the vibration, rhythmical stimulation is given to the head to make the person feel mood. It is possible to renew it.

Further, it is generally practiced to hit the head with a brush to stimulate the hair roots to promote blood circulation, prevent hair loss, and promote hair growth. However, if this vibrating device 1 is used, it is necessary to hit the hair. You just have to press it. In addition, when a music signal is used to cause a sound of music to flow from the vibrating surface of the vibrating device 1, if a song is selected and vibrated, the playing time can be set as the pressing time. Alternatively, an emotional signal may be flown for a certain period of time by a timer and used as the pressing time. Further, since the music / emotional signal has a melody or rhythm change, it is possible to prevent the stimulation from becoming chronic due to vibration. When the scalp (skin) is itchy, the hair brush type vibration device 1 may be pressed without scratching with a finger or the like to promote comfort by vibration and suppress the itch.

As a modification of the above-mentioned vibrating device 1 of the hairbrush type, as shown in FIGS. 4 and 5, there is one in which plastic columnar unitary projections 4a are arranged in rows and columns, and the cushion 20 is provided at the base. Is provided so that the boundary surface of the plurality of protrusions 4a becomes concave when pressed.

Next, the helmet type vibration device 21 for head stimulation will be described with reference to FIGS. The two electromechanical vibration converters 3 provided in the vibration device 21 are connected by a frame body (support portion) 22, the weight balance is adjusted, and the plurality of protrusions 4 come into contact with the scalp and are stably mounted. .
The sensitivity to the stimulation of the head 19 differs depending on the location, so 2
The outputs of the two electromechanical vibration converters 3 are independently adjusted. Further, a cushion 23 that absorbs vibration is provided at a position where the frame body 22 contacts the head portion 19. Since both hands of the vibration device 21 are released, the vibration output can be adjusted with the vibration device 21 kept in contact with the head, and the optimum vibration, for example, a comfortable vibration can be delicately set.

Next, a stand type head stimulation vibration device 24 will be described with reference to FIGS. In the helmet type mentioned above, two electric / mechanical vibration converters 3 were attached, but if it is natural to enjoy vibration in the entire head, the electric / mechanical vibration converters integrated with the protrusions are considered. The vessel 3 is provided at a plurality of locations. Therefore, the weight load is reduced so that the head does not bear the entire weight as the weight increases.

In the vibrating device 24, the intermediate portion of the rod 26 is pivotally supported on the stand 25, the balance weight 27 is attached to one end of the rod 26, and the head cover 28 is attached to the other end. A chair 29 is installed below the head cover 28. The electric / mechanical vibration converter 3 is attached to the head cover 28 at the top, front, rear, left and right, and the projection 4 is provided inside.
Is projected. The position of the upper electro-mechanical vibration converter 3 can be displaced by the adjusting screw 30.

Although the head 19 is described in the above embodiment, it is also possible to apply vibration to a portion where the vibration plane of the electromechanical vibration converter 3 does not hit efficiently, for example, an arm when sitting. The hairbrush type can also be applied to grooming animals.

[0025]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, vibration is transmitted through the projections without contacting the vibrating surface of the vibration device for head stimulation with the body, and is blocked to the hair. However, since it matches the curved surface of the body, vibrations due to music and emotional signals can be reliably transmitted to the round surface such as the head. Also, unlike hum sounds, vibrations due to music and emotional signals are transmitted to the scalp through the protrusions, so they have a lot of stimulating effects, and work to promote blood circulation similar to a brush that hits the head to stimulate hair roots. Can be expected.
