Description

Description: TECHNICAL FIELD The present invention relates to headphones suitable for transmitting electric signals having a special waveform to the central nervous system in addition to music.

(Prior art) Recently, a new music therapy has been proposed to soften the pain of the body such as neuralgia by listening to classical tunes and light music for the treatment of geriatric diseases, and also to reduce and eliminate the severe pain of terminal cancer. It is implemented in some hospitals and nursing homes.

In such music therapy, in addition to visualizing music through the ear and hearing, it is necessary to transmit an electric signal of a special waveform to the pituitary gland, and headphones are used for that purpose. As such, it is not suitable for transmitting electrical signals to the pituitary gland and is therefore not suitable for such therapy.

(Objects and Configurations of the Invention) The present invention has been made in view of the above points, and an object of the present invention is to propose headphones suitable for music therapy. A sound generator is provided in a central portion, and pads around the sound generator are provided. At least the portion of the portion that touches the human body is made conductive and adhesive, the sound generator can be connected to an external sound source, and the conductive portion of the pad portion can be connected to an external special waveform electric signal source. .

(Example) Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is an external view of a headphone according to the present invention, which is almost the same in appearance as a conventional headphone for listening to music. Become. The earpieces 1, 1 can be slid so that their positions can be adjusted.

FIG. 2A is an enlarged sectional view of the earpiece 1, and FIG. 2B is a front view.

As is well shown in FIG.
Is a speaker 1c for sound generation in a space formed by a circular support plate 1a and a cover 1b fixed to the periphery of the support plate 1a.
Is built in, and the fixing portion between the support plate 1a and the cover 1b is a pad 1d.
Covered with. A coupling member 1e for slidably coupling the earpiece 1 to the headband 2 is attached to the center of the outside of the cover 1b.

The support plate 1a and the cover 1b are made of synthetic resin,
In the vicinity of the center of 1a, as shown in FIG.
A slit 1f for outputting sound from the outside to the outside is formed.

By the way, the feature of the headphones lies in the structure of the pad 1d, and this point will be described below.

As can be seen from FIG. 2 (a), the pad 1d is substantially semicircular (has a cross section) which comes into contact with the periphery of the ear when the headphones are worn.
The part a is made of a conductive and flexible material such as conductive silicone rubber, a conductive resin sheet or a conductive sponge, which has a property of closely adhering to the periphery of the ear. The circular portion (cross section) b is made of a material such as non-conductive silicone rubber, resin sheet, sponge rubber, or the like. The inside of the pad 1d is filled with an elastic material 1g such as a vinyl cushion or sponge, or water, jelly-like or gel-like high-viscosity material, air or gas when liquid-tight or air-tight sealing is possible. It is preferable that the filling material is filled and resonates with the waveform of the electric signal transmitted from the outside in the case of the latter filling material.

The semicircular portion a of the pad 1d is connected through a wire 3 to a special waveform generator such as an external pulse therapy device. The speaker 1c is connected via a wire 4 to an external sound source such as a player or a tape recorder.

In use, the headphones 1, 1 are applied to both ears, and a special waveform electric signal is supplied to the semicircular portion a of the pad 1d from an external pulse therapy device via the wire 3, and the speaker 1c is used.
By supplying a music signal from an external sound source through the wire 4 to the user, an electric signal is transmitted to the user via the pad 1d as a stimulus and the music from the speaker 1c is perceived by the auditory sense from the slit 1f. Is done. In this case, since the semicircular portion a of the pad 1d is in close contact with the periphery of the ear, external sound can be cut off. Therefore, if these headphones are used for the treatment of geriatric diseases such as blurring of the elderly and neuralgia, and for the analgesia of terminal cancer, an epoch-making analgesic effect can be expected.

(Effects of the Invention) As described above, in the present invention, a sound generator is provided in the center, and at least a portion of the surrounding pad portion that touches the human body is made conductive and adherent, and the sound generator is connected to an external sound source. And the conductive portion of the pad can be connected to an external special waveform electrical signal source. Because the electric signal of the special waveform output from the pad part is transmitted to the central nervous system such as the pituitary gland through the skin, analgesia is possible in addition to music therapy,
It is particularly effective in the field of geriatric medicine.
