Abstract

PROBLEM TO BE SOLVED: To provide a hearing aid which can transmit acoustic signals directly to cranial bones not through air and the drum. SOLUTION: This hearing aid is presumed to receive acoustic signals from an earphone jack of an audio device etc. First, acoustic signals from an audio device 10 are transmitted to a vibrating means 30 by way of an acoustic signal transmitting pathway 20 connected to the audio device 10. The acoustic signals transmitted to the vibrating means 30 are converted to mechanical vibration by the vibrating means 30. The converted mechanical vibrations are transmitted to a bone vibrator 40 connected to the vibrating means 30. Since the bone vibrator 40 vibrates, the acoustic signals are transmitted to the cranial bones as mechanical vibration.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hearing aid, and more particularly to a hearing aid that transmits an acoustic signal directly to the skull without passing through air or the eardrum.

[0002]

2. Description of the Related Art Hearing aids for amplifying and transmitting sound waves have been provided for people with hearing loss.

[0003]

However, since the hearing aid transmits the amplified sound wave through the air and the eardrum, it is not effective for a deaf person who cannot sense sound through the eardrum.

[0004] Further, since hearing aids pass through the air, there is a problem that noise is generated when listening to music or the like from an acoustic device. The present invention has been proposed based on the above-mentioned conventional circumstances, and has as its object to provide a hearing aid that transmits an acoustic signal directly to the skull without passing through the air and the eardrum.

[0005]

The present invention employs the following means to achieve the above object. That is, the hearing aid of the present invention is premised on receiving an acoustic signal from an earphone jack of an acoustic device or the like as shown in FIG.

In the hearing aid, first, an acoustic signal from the acoustic device 10 is transmitted to the vibration means 30 via an acoustic signal transmission path 20 connected to the acoustic device 10. The acoustic signal transmitted to the vibration means 30 is converted into mechanical vibration by the vibration means 30.

The converted mechanical vibration is transmitted to the vibration means 3
The vibration is transmitted to the bone vibrator 40 connected to the zero. Bone vibrator 4
By vibrating 0, the acoustic signal is transmitted to the skull as mechanical vibration.

That is, the acoustic signal from the acoustic device 10 is transmitted directly to the skull without passing through the air and the eardrum.

[0009]

FIG. 2 is a schematic view showing the appearance of an embodiment of the present invention. The hearing aid of the present invention includes an acoustic signal transmission path 20 for transmitting an acoustic signal from the acoustic device 10, a motor 31 having a rotor 32 that forms mechanical vibrations in accordance with the acoustic signal, and a rotor 32. And a bone vibrating body 40 connected to the mechanical vibration of. The bone vibrator 40 is used in a state of being bitten by upper and lower teeth.

In the hearing aid, first, an audio signal as an electric signal is transmitted from the earphone jack 11 on the audio device 10 through the audio signal transmission path 20 to the motor 31.
Is transmitted to

The motor 31 operates according to the transmitted sound signal. That is, the acoustic signal is converted by the motor 31 from an electrical signal into mechanical vibration. The converted mechanical vibration is transmitted to the bone vibrating body 40 connected to the rotor 32.

Since the bone vibrator 40 is used in a state of being bitten by the upper and lower teeth, the acoustic signal is transmitted to the skull via the upper and lower teeth by vibrating the bone vibrator 40. Normally, sound waves are transmitted to the auditory nerve by vibrating the eardrum, but according to the present invention, they are transmitted to the auditory nerve via the skull without passing through the eardrum.

The material of the bone vibrator 40 is not particularly limited as long as it transmits vibration. Further, the bone vibrator 40 is
It is desirable that the upper and lower teeth have a shape that is easy to bite.

[0014]

According to the present invention, it is possible to provide a hearing aid which transmits an acoustic signal directly to the skull.

Therefore, the hearing aid of the present invention can be used not only for hearing-impaired persons but also for deaf persons. Also,
Since the air does not pass through, there is an effect that noise does not enter.
