Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a hearing aid sound collector that is attached to the back of the ear shell when the person is not deaf but has difficulty hearing speech or sounds from a distance.

[Conventional technology and its problems]

When listening to a lecture in a lecture hall, etc., if you are too far away from the lecturer and it is difficult to hear what is being said, or if you want to hear the sounds of distant birds in the fields or mountains, you can listen by placing your palms behind your ear shells. It becomes easier.

By the way, it is possible to put your palm on the back of your ear temporarily, but not only can you not use your hand in this state, but if you continue in this state for a long time,
My arms are tired and painful.

This invention attempts to solve the above problems, and its purpose is to provide a hearing aid sound collector that can be easily attached to and detached from the ear shell, and that can be attached reliably and stably. be.

[Means for solving problems]

In order to solve the above problems, this idea
A bowl-shaped sound collector main body 1 is cut out on one side of its periphery to form a notch 2 that surrounds the base of the auricle from the rear side, and a cutout 2 that surrounds the base of the auricle from the rear side is formed at both ends of the notch 2. A locking member 3 having a flexible length that wraps around the
is attached to the back surface of the sound collector main body 1, and when the locking member 3 is wrapped around the ear shell, it comes into contact with the head and elastically presses the inner surface of the sound collector main body 1 against the rear surface of the ear shell. A support member 4 is attached, and the main body 1 of the sound collector is held in an upright state on the ear shell by the support of the support member 4 and the locking member 3.

[Effect]

In the hearing aid sound collector having the above structure, the locking member 3 is attached by wrapping it around from the rear side of the ear shell.
In this installed state, the support member 4 presses the sound collector main body 1 against the ear shell, so the sound collector main body 1 is pressed against the rear surface of the ear shell and is held in an upright state, making it stable without falling down. and fixed.

[Example] FIG. 1 shows an example of a hearing aid sound collector according to the present invention. 1 is mainly a sound collector and has a bowl shape.
There is a linear notch on one side of the circumference, and a locking member 3 made of a flexible wire is attached to the notch 2 along the notch edge, and both ends a, b is made to protrude from both ends of the notch portion 2 by a required length.

One end of a support member 4 is fixed near the center of the bulge side of the sound collector main body 1, with the other end facing toward the notch 2, and the other end protrudes a required length from the notch 2. There is.

The sound collector main body 1 is shown as an example of one made of a firm leather material, and an oval hole 5 is cut in the center of the leather cut into an approximately circular shape, and a hole 5 is cut in the center of the edge of the hole on one of the long sides. A required area of the outer skin is cut out near the area and glued together, and the hole is closed by pasting a circular piece of skin 6. Reference numeral 7 indicates the abutting portion of the hole 5 after it has been cut out from the edge of the hole.

The area of the sound collector main body 1 is larger than the ear shell B, as shown in FIG.

The main body of the sound collector and the supporting material may be made of not only a leather material but also other soft elastic materials, or may be an integrally molded product of a soft organic polymer.

This hearing aid sound collector A is placed behind the ear shell B as shown in FIG. Place it behind the ear shell, facing towards the base. Next, both ends a and b of the locking member 3 protruding from both ends of the notch 2
Fold it back to the front side of the ear shell so as to hold the upper and lower edges of the base of the ear shell, and insert it into the recess 8 where the ear hole is located at the end of the locking member.

In this state, the support member 4 comes into contact with the head and deforms, as shown in FIG. 2, and presses the sound collector main body 1 toward the ear shell B. Therefore, the sound collector main body 1 is held in an upright state with its inner surface pressed against the rear surface of the ear shell B. In this state, the elastic force of the support member 4 and the holding force of the locking member 3 prevent the sound collector main body 1 from falling down, and the sound collector main body 1 stands up on the rear side of the ear shell B. , can effectively focus sound to the ears.

Note that the locking members for the ear shell provided at both ends of the notch of the sound collector main body 1 are not limited to the flexible filament, but may be locking members of other shapes.

〔effect〕

The hearing aid sound collector of this invention has the following effects.

(1) The main body of the sound collector is bowl-shaped and has a cutout on one side of its circumference, so by supporting it behind the ear shell, it is similar to placing the palm of the hand on the back of the ear shell. Can hear distant conversations and sounds.

(2) The flexible locking member can be deformed to fit the shape of the ear shell and wrapped around it.
To reliably attach a sound collector to an ear shell of any shape or size.

(3) By pressing the main body of the sound collector toward the ear shell, the support material can press the main body of the sound collector against the rear surface of the ear shell and hold it in an upright position, so that the sound collector does not fall over. It can be fixed stably without any problems, and the sound can be efficiently focused in the ear.

Claims (1)

[Claims for Utility Model Registration] (1) A sound collector main body 1 having a bowl shape is cut out on one side of its circumference to form a notch 2 that surrounds the base of the ear shell from the rear side, and the notch A flexible locking member 3 having a length that wraps around the front side of the base of the ear shell is attached to both ends of the sound collector body 1, and the locking member 3 is attached to the back surface of the sound collector main body 1 and is wrapped around the ear shell. A support member 4 is attached that comes into contact with the head and elastically presses the inner surface of the sound collector main body 1 against the rear surface of the ear shell. A hearing aid sound collector characterized in that 1 is held in an upright position on the ear shell. (2) The hearing aid sound collector according to claim 1, wherein the sound collector main body 1 and the support member 4 are made of soft elastic materials.
