Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an in-the-ear hearing aid that is used by being inserted into the external ear or external auditory canal, and is particularly suitable for application to a custom in-ear hearing aid.

By the way, a custom in-the-ear hearing aid is a hearing aid that is manufactured to suit the shape and hearing level of each individual's outer ear and canal. In other words, a microphone, earphones, amplifier, etc. that match the individual's hearing level are placed inside a synthetic resin ear-shaped case (earmold) that is manufactured to fit the shape of the outer ear and ear canal of each individual wearing the hearing aid. A hearing aid that incorporates a hearing aid body. In this case, the ear-shaped case also functions as an ear-shaped ear sensor.

[Background technology and its problems]

In-the-ear hearing aids are inserted firmly into the outer ear and ear canal, so there is no clue when taking them out, which is particularly difficult for elderly people and young children.

This inconvenience was particularly noticeable in custom in-the-ear hearing aids. This is because, as mentioned above, the external shape of this hearing aid, that is, the ear-shaped case (earmold), is manufactured to fit the outer ear and ear canal of each hearing aid wearer. This is because it has become even more difficult to remove.

Conventionally, in-the-ear hearing aids, especially custom in-the-ear hearing aids, have not been proposed that take these points into consideration. This is based on the premise that hearing aid developers are aiming for miniaturization in response to the desire of hearing-impaired people to create hearing aids that are inconspicuous.In addition, large in-the-ear hearing aids that protrude outside the outer ear in order to take them out are This is because there was psychological resistance in the first place because it went against the original development concept. Also, as a practical matter,
The area of the end face facing the outside world of an in-ear hearing aid when inserted into the outer ear or ear canal is small to begin with, and various operating members such as a volume switch, battery case cover, etc. are densely arranged on the end face. Moreover, it was difficult to find room for providing additional means for taking out the device.

[Purpose of invention]

This invention was made in view of the above-mentioned problems, and aims to provide an in-the-ear type hearing aid that makes it possible to easily take out a hearing aid inserted into the external ear or external auditory canal.

[Summary of the invention] In order to achieve this object, according to the invention, in a hearing aid case in which a battery case cover is pivotally coupled to a support shaft provided on the hearing aid case, a take-out member is pivotally supported on this support shaft. Make it join.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view of a custom in-the-ear hearing aid, and FIG. 2 is a plan view thereof.

This hearing aid consists of a shell 1 that is generally hollow inside and a face plate 2 that includes components necessary for a hearing aid, such as a microphone, a battery case, a volumetric volume, an amplifier, and a gain adjuster.
Incidentally, when this hearing aid is inserted into the external ear and external auditory canal, the face plate 2 faces the outside world.

The shell 1 is made by first making a mold of the outer ear and external auditory canal for each hearing aid wearer using an impression material, using this as a mother mold, and then making a mother mold of plaster or the like, and using this mother mold, molding with synthetic resin. Made. The thickness of shell 1 is approximately 1
~2m/m. Note that this shell 1 has both the function of an ear sensor and a function of a hearing aid case.

The face plate 2 is molded from a hard synthetic resin in order to stably and firmly hold each component.

The shell body 1 and the face plate 2 are coupled and fixed by an appropriate means such as an adhesive to form a hearing aid case.

Now, 3 is a microphone sound hole, which communicates with a microphone (not shown) housed within the shell body 1. Reference numeral 4 denotes a volume with an ON-OFF switch, which is electrically connected to an electric circuit section (not shown) also housed within the shell 1. Second
Although not shown, a gain adjuster or the like may be disposed on the face plate 2 shown in the figure. 5 is a lid of the battery case, which together with the recess 6 provided in the face plate 2 constitutes the battery case. 7 is a button type battery, and 8 is a sound outlet hole that releases amplified sound into the ear canal. Although 9 is a ventilation hole, it is not necessarily provided.

By the way, the battery case lid 5 has one end 5A pivotally connected to the face plate 2 and is configured to be openable and closable. 10 is a support shaft. This support shaft 10
is supported by a U-shaped support base 11 formed on the face plate 2. Motomo support shaft 1
Various other types of support means for the 0 can be considered. For example, a recess may be formed in the face plate 2 and a support shaft may be provided in the valley. Furthermore, instead of the U-shaped support base, a pair of opposing cubes may be used as the support base. In addition, the other end 5B of the lid 5 is
It is connected to the face plate 2 with a snap. Therefore, the lid 5 can be opened by releasing this snap connection.

Reference numeral 12 denotes a take-out member, which is pivotally coupled to the same support shaft 10 as the lid 5. A recess 13 corresponding to the shape of the take-out member 12 is formed in the lid 5. The take-out member 12 is normally accommodated in this recess 13. Further, the head 14 of the take-out member 12 is slightly raised to make it easy to pick up with fingers or toes.
Furthermore, a half-moon-shaped recess 15 is formed in the lid 5 near the head 14 of the take-out member 12.
It is made easy to pick.

Next, we will discuss the effect.

To remove the hearing aid from the outer ear and ear canal, first slide the tip of your toe over the half-moon-shaped recess 15 in the lid 5.
The head 14 of the take-out member 12 is pulled out from the recess 13 of the lid 5. FIG. 3 is a diagram showing the state of the take-out member 12 pulled out in this manner. After that,
Pinch this removal member 12 with your fingers or nails and pull it out. Therefore, the hearing aid coupled with the removal member 12 is also removed from the outer ear and external auditory canal. Note that the pulled-out takeout member 12 is then accommodated in the recess 13 formed in the lid 5 and returns to its normal state.

By the way, in the above embodiment, the head 14 of the take-out member 12 is slightly curved in order to serve as a cue for raising the take-out member 12, making it easy to pick up, but the invention is not necessarily limited to this. . In short, in order to pick up the take-out member, it is sufficient to have an appropriate means for raising the take-out member first.
For example, a spherical protrusion may be formed on the head of the take-out member to serve as a cue for raising the take-out member.

[Effect of idea]

As mentioned above, the present invention has a small area, and the microphone, operation section, etc. (each component)
The ejection member is provided on the overcrowded end face (face plate) of the battery case by cleverly utilizing the support means of the lid of the battery case that already exists. By using this removal member as a handhold, it becomes possible to easily take out the in-ear hearing aid inserted into the outer ear and external auditory canal, which is particularly convenient for the elderly and young children.
