Abstract

PROBLEM TO BE SOLVED: To provide a hearing aid that delivers a stereoscopic sound to elderly people and audibly handicapped people in on ear by taking directivity of the human ears into account in order to solve problems that such people above are hard to hear utterance of an opposite party during conversation such as repetition of questions or putting one's hand over one's ear, take much time to judge from which direction the voice is coming when addressed resulting in encountering a danger on the way of walking on a road. SOLUTION: Two sets each of a directional microphone case 4 and a voice tube attached loudspeaker case 6 that are coupled at a distance are provided. A microphone is mounted at a position close to side of both eyes at a height of eyes by using a temple 5 of a ear hook frame of eyeglasses or the like, and the loudspeaker 6 is mounted this side of a tip cell 7 closer to ear holes. A sound collection port 12 is directed in the ear direction, the voice received from an opposite party is converted into an amplified voice with a characteristic by the voice tube attached loudspeaker case 6 and sounds toward the ear drum from a position leading to the depth of the ear hole through the voice tube 8. Since the voice tube 8 is not in direct contact with the skin of the wearer but semi-fixed at a position closer to the ear drum, falling of the hearing aid is not cared about at all and no pressure like by a ear plug is caused.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hearing aid that enhances the directivity of left and right ears of a distant elderly person or a hearing-impaired person, and sends stereophonic sound to the eardrum of the ear. It is a hearing aid that adjusts and transmits.

[0002]

2. Description of the Related Art In a conventional hearing aid, the left and right ears can be individually loudspeaked according to the audibility, and the loudspeaker output can be adjusted. No hearing was found, and the hearing aid directly touched the skin of the ear, giving a sense of pressure.

[0003]

In the conventional hearing aid, there are many independent hearing aids, and it is difficult to determine the direction of the sound that can be heard, and there is no function of transmitting sound to the eardrum simultaneously in three dimensions. Also, the hearing aid touches the skin of the ear, so that the wearer feels pressure.

[0004]

Means for Solving the Problems The position of the microphone device housing, such as glasses, attached to the lens frame is on both sides of both eyes of the wearer, and one directional microphone is placed at a position equidistant in front of the ear. Installing. The voice input from the microphone port has directivity and a high ability to detect the voice direction, and the voice output passes through the piping in the ear-hook temple with extra-fine power wiring, and is attached to the base of the previous cell Connect to the wiring of the loudspeaker with loudspeaker. The sound loudspeaked from the housing of the loudspeaker with a loudspeaker passes through the loudspeaker by sound waves and reaches the eardrum at the back of the ear canal from the distal end of the loudspeaker which is piped to a position where the ear canal is viewed. For hearing aids for people with a hearing difference between the left and right, it is corrected to the frequency range of the high and low range according to the individual audibility of the ear, and the loudspeaker output sounds to the eardrums of the left and right ears in a balanced manner and enhances the stereoscopic performance, Becomes possible. Power is supplied from batteries individually incorporated in the microphone device housing. The power supply wiring to the microphone device housing and the loudspeaker housing with a sound tube is hidden and wired in the extra-fine piping provided in the ear-hanging temple, and is not exposed.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the top view of FIG. 1, the product of the present invention uses a frame hinge (3) such as glasses and a temple for ear hanging (5), and a microphone device housing is placed next to both eyes. The body is worn, and the loudspeaker housing with voice tube (6) is mounted at a position slightly away from the microphone housing and in front of the front cell (7) near the ear hole.

[0006] The microphone device housing (4) and the loudspeaker with loudspeaker (6) are connected, and the two sets are separately wired so that the hearing aid function is performed. For each set, the right microphone device housing (4) is on the right ear and the left microphone device housing (6)
Is a function for transmitting sound to the left ear.

In FIG. 2, the function of the hearing aid function by combining the microphone device housing (4) and the loudspeaker with loudspeaker (6) is that the sound frequency compensating device for the high and low frequency ranges of the sound individually collected. It can be adjusted by (15) and the loudspeaker output adjusting device (14).

Since the microphone device housing (4) is mounted on the side where the temple (5) is attached to each hinge (3) on the left and right of the frame such as glasses, the sound collection port (12) of the microphone device housing (4) is Wear it so that it faces your ear when wearing. The battery is built in the microphone device housing (4), and the battery can be removed when it is exhausted.

The power supply 0N and 0F of the battery in the microphone device housing (4) are connected to a lever (10) extending from the switch lever (10) of the power supply also in the microphone device housing (4). Frame hinges (3)
Is mounted on the opposite metal wall so that the OF is activated when pressed when folded.

The wiring coming out of the microphone device housing (4) is concealed inside the ear-hook temple (5) of the frame such as glasses, and is installed at a position close to the ear hole. The wiring is drawn out and connected at the mounting position of the loudspeaker.

In FIG. 2, the voice tube (8) is made of a flexible hard rubber tube. When the voice tube is attached, the tube is bent so as not to touch the skin of the wearer's cheek, and the voice tube tip opening (8) is attached. Semi-fixed so that is stable at the position facing the eardrum in the ear canal.

[0012] Both the loudspeaker housing with a sound tube (6) and the microphone housing (4) have a waterproof and moisture-proof structure, and the entire housing is processed so as to eliminate moisture.

[0013] Since both the speaker housing with sound tube (6) and the microphone housing (4) are mounted on the left and right temples (5) such as eyeglasses, the attachment / detachment is required when replacing with other glasses or the like. Make it possible. In this case, disconnection of the wiring is involved.

[0014]

As the age increases, a person's hearing function declines and the voice of the other party can be heard, but the spoken word itself cannot be heard clearly and the meaning cannot be understood. Therefore, I can't respond as expected, and I feel uncomfortable about the other party. In such a case, if you look at the other party's mouth, the sound that is simultaneously amplified from the two microphones in front of both eyes will sound three-dimensionally, so you can talk comfortably and need to listen back and forth many times Disappears.

A person with hearing impairment on one side cannot determine the direction in which the voice was heard, looks around, and feels ashamed. In such a case, the sound of the other party is adjusted and heard by the left and right ears by the operation of the two microphones, so that the direction of the voice can be determined by itself and the face can be turned to the other party.

In a meeting or the like, if there is no vacant seat where the voice passes, the user may feel disappointed. In such a case, if you look at the mouth of the other speaker, the microphone in front of your ear will increase the directivity, and you will be able to hear the speaker's voice a little further away.

The use of a voice tube completely releases the ear canal skin. There is no earplug-like pressure on the ear skin, and you can definitely hear the loud sound, so you don't have to worry about noise other than the surrounding voice, you can listen together from the space of the ear canal, and a three-dimensional hearing aid It becomes possible.

Since the material of the voice tube is rubber, there is no damage even if it is touched by a hand or the like, and there is no fear that the hearing aid falls off from the ear hole as in the case of a hearing aid. The discomfort during use of the product of the present invention is such that it is felt as slightly heavy glasses.
