Description
本発明は、補聴器や耳せんなどの音出力口に耳垢が侵入するのを防止する耳垢侵入防止チップ及びそれを用いた補聴器に関する。 The present invention relates to an earwax intrusion prevention chip for preventing earwax from entering a sound output port of a hearing aid or earplug and a hearing aid using the same.
従来、耳あな型補聴器の音出力口やイヤホンを耳せん内部に備える耳かけ型補聴器の音出力口には、耳垢がイヤホンに入り込むのを防ぐために、耳垢侵入防止チップが取り付けられている。このような耳垢侵入防止チップとしては、イヤホンに耳垢が落ち込まないように、耳垢をトラップする構造が知られている(例えば、特許文献1参照)。また、イヤホンに耳垢が落ち込まないように、音を伝える導管が複雑に入り組んだ形にした耳垢侵入防止チップが開示されている(例えば、特許文献2参照)。 Conventionally, an earpiece intrusion prevention chip is attached to a sound output port of an earphone type hearing aid or an earphone type hearing aid equipped with an earphone inside the earplug in order to prevent the earwax from entering the earphone. As such an earwax intrusion prevention chip, a structure for trapping earwax is known so that earwax does not fall into the earphone (see, for example, Patent Document 1). In addition, there has been disclosed an earwax intrusion prevention chip in which a conduit for transmitting sound is complicatedly arranged so that earwax does not fall into the earphone (see, for example, Patent Document 2).
しかし、イヤホンに耳垢が落ち込まないように、耳垢をトラップする構造にしても、トラップした耳垢で音出力口が塞がれてしまうという問題がある。また、イヤホンに耳垢が落ち込まないように、音を伝える導管を複雑に入り組んだ形にしても、外耳道挿入方向に音道が設けられているので、詰まり易いという問題がある。 However, even if the earwax is trapped so that the earwax does not fall into the earphone, there is a problem that the sound output port is blocked by the trapped earwax. In addition, even if a conduit for transmitting sound is complicatedly arranged so that ear wax does not fall into the earphone, there is a problem that the sound path is provided in the insertion direction of the external auditory canal so that clogging easily occurs.
本発明は、従来の技術が有するこのような問題点に鑑みてなされたものであり、その目的とするところは、たとえ耳垢が付着しても、全ての音を伝える通路が塞がり難い耳垢侵入防止チップ及び補聴器を提供しようとするものである。 The present invention has been made in view of such problems of the prior art, and the object of the present invention is to prevent the invasion of earwax, which is difficult to block the passage of all sounds even if earwax adheres. A chip and a hearing aid are to be provided.
上記課題を解決すべく請求項1に係る発明は、補聴器などの音出力口に装着される耳垢侵入防止チップであって、前記音出力口にほぼ全体が挿入される略円筒形状で両端開放の音導部と、この音導部の一端に形成され開口部を有する鍔部からなり、この鍔部の外側と前記音導部の内側を連通する通路を前記開口部の他に設け、前記通路は、前記鍔部の裏面に形成した溝と、この溝に続く前記音導部の壁面に開けた貫通孔からなるものである。 In order to solve the above-mentioned problem, the invention according to claim 1 is an ear wax intrusion prevention chip attached to a sound output port of a hearing aid or the like, and is a substantially cylindrical shape that is almost entirely inserted into the sound output port and is open at both ends. The passage includes a sound guide portion and a flange portion formed at one end of the sound guide portion and having an opening, and a passage that communicates the outside of the flange portion and the inside of the sound guide portion is provided in addition to the opening portion. Consists of a groove formed on the back surface of the flange and a through-hole opened in the wall surface of the sound guide part following the groove .
請求項2に係る発明は、請求項1記載の耳垢侵入防止チップにおいて、前記通路を少なくとも2つ形成した。 According to a second aspect of the present invention, in the earwax intrusion prevention chip according to the first aspect, at least two of the passages are formed.
請求項3に係る発明は、請求項1又は2記載の耳垢侵入防止チップにおいて、前記音導部に音響抵抗を設けた。 According to a third aspect of the present invention, in the earwax intrusion prevention chip according to the first or second aspect , an acoustic resistance is provided in the sound guide portion.
請求項4に係る発明は、請求項1、2又は3記載の耳垢侵入防止チップにおいて、前記鍔部を周縁に近づくに従って薄く形成すると共に、前記開口部のエッジをR加工している。 According to a fourth aspect of the invention, in the earwax intrusion prevention chip according to the first, second, or third aspect , the heel portion is formed thinner as it approaches the periphery, and the edge of the opening portion is R-processed.
請求項5に係る発明は、請求項1乃至請求項4のいずれかに記載の耳垢侵入防止チップを装着するものである。 According to a fifth aspect of the invention, the earwax intrusion prevention chip according to any one of the first to fourth aspects is mounted.
請求項1に係る発明によれば、音導部の開口部の他に、鍔部にも音を伝える通路が確保されるので、音導部の開口部が耳垢で塞がっても、音を出力することができる。また、鍔部の裏面に形成した溝と、この溝に続く音導部の壁面に開けた貫通孔からなる通路を形成することは、鍔部に貫通孔を設ける通路より金型加工が比較的容易なので、部品単価を安くすることができる。 According to the first aspect of the invention, in addition to the opening portion of the sound guide portion, a passage for transmitting sound to the buttocks is secured, so that sound is output even if the opening portion of the sound guide portion is blocked with ear wax. can do. In addition, forming a passage formed of a groove formed on the back surface of the collar portion and a through hole opened in the wall surface of the sound guide portion following the groove is relatively easier to mold than a passage having a through hole in the collar portion. Since it is easy, the unit price can be reduced.
請求項2に係る発明によれば、音導部の開口部の他に、鍔部にも音を伝える通路を複数設けるので、いくつかの開口部に耳垢が付着しても、全ての通路が塞がれるまで音を出力することができる。 According to the second aspect of the invention, in addition to the opening of the sound guide portion, a plurality of passages for transmitting sound are also provided to the buttocks, so even if ear wax adheres to some openings, all the passages Sound can be output until it is blocked.
請求項3に係る発明によれば、補聴器などに音響抵抗を設けるのではなく、着脱容易な耳垢侵入防止チップに音響抵抗を設けることにより、煩雑な音響抵抗の交換作業を必要としない。音響抵抗の交換は、耳垢侵入防止チップにおいて容易に行うこともできるし、または耳垢侵入防止チップ自体を交換すれば済むことになる。 According to the third aspect of the present invention, the acoustic resistance is not provided to the hearing aid or the like, but the acoustic resistance is provided to the earpiece intrusion prevention chip that is easy to attach and detach, thereby eliminating the need for complicated replacement of the acoustic resistance. The replacement of the acoustic resistance can be easily performed in the earwax intrusion prevention chip, or the earwax intrusion prevention chip itself can be replaced.
請求項4に係る発明によれば、鍔部の周縁および音導部の開口部に角張ったエッジがなくなるので、耳あな型補聴器などを外耳道に挿入する際に、外耳道に付着した耳垢を削り取ることが少なくなり、開口部や通路が耳垢で詰まることが少なくなる。 According to the invention of claim 4 , since there are no angular edges at the periphery of the buttocks and the opening of the sound guide, the earwax attached to the ear canal is scraped off when an ear hearing aid is inserted into the ear canal. And the openings and passages are less likely to become clogged with earwax.
請求項5に係る発明によれば、耳垢侵入防止チップを装着することにより、イヤホンに耳垢が落ち込む可能性がなくなる。また、仮に耳垢侵入防止チップの鍔部の開口部及び全ての通路に耳垢が詰まったとしても、耳垢侵入防止チップを容易に交換することができるので、より快適に補聴器を装用することができる。 According to the fifth aspect of the present invention, by mounting the earwax intrusion prevention chip, there is no possibility that the earwax falls into the earphone. Moreover, even if the earwax is clogged in the opening of the buttocks and all the passages of the earwax intrusion prevention chip, the earwax intrusion prevention chip can be easily replaced, so that the hearing aid can be worn more comfortably.
以下に本発明の実施の形態を添付図面に基づいて説明する。ここで、図1は本発明に係る耳垢侵入防止チップの3方向の斜視図、図2は同じく断面図、図3は音響抵抗の取り付け状態を示す断面図、図4は耳垢侵入防止チップを装着した耳あな型補聴器の斜視図、図5は同じく断面図、図6は耳垢侵入防止チップの変形例の正面図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a perspective view in three directions of an earwax intrusion prevention chip according to the present invention, FIG. 2 is a sectional view of the same, FIG. 3 is a sectional view showing an attachment state of acoustic resistance, and FIG. FIG. 5 is a cross-sectional view of FIG. 5 and FIG. 6 is a front view of a modified example of the earwax intrusion prevention chip.
本発明に係る耳垢侵入防止チップ1は、図1に示すように、補聴器や耳せんなどの音出力口にほぼ全体が挿入される略円筒形状で両端開放の音導部2と、この音導部2の一端に形成され開口部3を有する鍔部4からなり、ポリエチレンなどの樹脂により一体に形成されている。鍔部4は周縁に近づくに従って薄く形成されている。開口部3のエッジにはR加工が施されている。開口部3には、大きな耳垢の侵入を防ぐために十字状に配置された柵5が設けられている。柵5の配置形状は、十字状に限らず、放射状、同心円状、スリット状、格子状など十分に開口面積を確保できればよい。 As shown in FIG. 1, the earwax intrusion prevention chip 1 according to the present invention has a substantially cylindrical sound guide portion 2 that is almost entirely inserted into a sound output port of a hearing aid, earplug, etc. The flange portion 4 is formed at one end of the portion 2 and has an opening 3 and is integrally formed of a resin such as polyethylene. The collar part 4 is formed thinly as it approaches the periphery. The edge of the opening 3 is subjected to R processing. The opening 3 is provided with a fence 5 arranged in a cross shape in order to prevent large earwax from entering. The arrangement shape of the fence 5 is not limited to a cross shape, but may be a radial shape, a concentric circle shape, a slit shape, a lattice shape, or the like as long as a sufficient opening area can be secured.
また、音導部2の他端には、補聴器や耳せんなどの音出力口に挿入し易いようにテーパ2aが形成されている。更に、テーパ2a近傍の音導部2外周には、耳垢侵入防止チップ1が補聴器や耳せんなどから抜け落ちるのを防ぐためのリング状のストッパ6が設けられている。また、鍔部4の裏面4aには、溝7が形成され、図2に示す音導部2の壁部に開けられた貫通孔8と共に、鍔部4の外側と音導部2の内側を連通する通路9を構成している。 Further, a taper 2a is formed at the other end of the sound guide portion 2 so that it can be easily inserted into a sound output port such as a hearing aid or an ear plug. Further, a ring-shaped stopper 6 is provided on the outer periphery of the sound guide portion 2 in the vicinity of the taper 2a to prevent the earwax intrusion prevention chip 1 from falling off from a hearing aid or an earplug. Further, a groove 7 is formed on the back surface 4a of the flange portion 4, and the outside of the flange portion 4 and the inside of the sound guide portion 2 are formed together with the through hole 8 opened in the wall portion of the sound guide portion 2 shown in FIG. A communication passage 9 is formed.
ここで、溝7に代えて鍔部4に貫通孔を設けることも考えられるが、耳垢侵入防止チップ1が耳あな型補聴器の鼓膜側先端に取り付けられる非常に小さい部品であることから、鍔部4に貫通孔を設けることには非常に難しく高い技術とコストを要する。従って、鍔部4に溝7を設ける方が、金型加工が比較的容易になるので、部品単価を安くすることができる。 Here, although it is conceivable to provide a through hole in the heel part 4 instead of the groove 7, the ear part intrusion prevention chip 1 is a very small component attached to the eardrum side tip of the ear hole type hearing aid. It is very difficult to provide a through hole in 4 and requires high technology and cost. Accordingly, it is relatively easy to form the mold 7 by providing the groove 7 in the flange portion 4, so that the unit price can be reduced.
また、図3に示すように、音導部2内にダンパやスポンジなどの音響抵抗10を配設することもできる。音導部2の内壁には、音響抵抗10が脱落しないように、リング状のストッパ11が設けられている。なお、音響抵抗10は軽量なので、ストッパ11を設けなくても適度な大きさの音響抵抗10を音導部2内に嵌挿するだけでもよい。 In addition, as shown in FIG. 3, an acoustic resistor 10 such as a damper or a sponge can be disposed in the sound guide portion 2. A ring-shaped stopper 11 is provided on the inner wall of the sound guide portion 2 so that the acoustic resistance 10 does not fall off. Since the acoustic resistor 10 is lightweight, the acoustic resistor 10 having an appropriate size may be merely inserted into the sound guide portion 2 without providing the stopper 11.
音響抵抗10の本来の役割は、出力音のピークを抑えることであるが、耳垢がイヤホンへ落ち込むのを防ぐ役割も果たす。しかし、従来の音響抵抗は、補聴器のイヤホンと音出力口をつなぐチューブ内に配置されていたので、音響抵抗の交換作業は高度な技術を要し煩雑であった。本発明では、音響抵抗10を耳垢侵入防止チップ1内に配置することによって、音響抵抗10の交換が容易になる。 The original role of the acoustic resistor 10 is to suppress the peak of the output sound, but it also serves to prevent the earwax from falling into the earphone. However, since the conventional acoustic resistance is arranged in a tube that connects the earphone of the hearing aid and the sound output port, the replacement of the acoustic resistance requires a high level of technology and is complicated. In the present invention, the acoustic resistor 10 can be easily replaced by disposing the acoustic resistor 10 in the earwax intrusion prevention chip 1.
耳垢侵入防止チップ1は、図4に示すように、耳あな型補聴器15の音出力口に音導部2を嵌挿することにより装着される。耳垢侵入防止チップ1は、周縁に行くに従い薄くなっているので、耳あな型補聴器15の音出力口周辺のケースから、徐々に盛り上がるような外観となる。同様に、耳せん内にイヤホンを内蔵するタイプの耳かけ型補聴器についても、耳せんに耳垢侵入防止チップ1を装着することができる。また、イヤモールドや、既製の耳せんに装着してもよい。内部へ耳垢が侵入することを防ぐ効果やハウリングを抑制する効果がある。 As shown in FIG. 4, the ear wax intrusion prevention chip 1 is mounted by inserting the sound guide portion 2 into the sound output port of the ear hole type hearing aid 15. The earwax intrusion prevention chip 1 becomes thinner as it goes to the periphery, so that the appearance gradually rises from the case around the sound output port of the ear hole type hearing aid 15. Similarly, with respect to the ear-type hearing aid of the type in which the earphone is incorporated in the earplug, the earwax intrusion prevention chip 1 can be attached to the earplug. Moreover, you may mount | wear with an ear mold or a ready-made earplug. It has the effect of preventing ear wax from entering the inside and the effect of suppressing howling.
また、図5に示すように、耳あな型補聴器15において、耳垢侵入防止チップ1を装着するには、イヤホン16をシェル17に取り付けるチューブ(ゴム製)18に直接嵌挿して装着することもできる。耳垢侵入防止チップ1の取り付け用のホルダを別途用意したり、シェル17の音出力口の形状を耳垢侵入防止チップ1が直接保持される形状にしたりすることもできる。 Further, as shown in FIG. 5, in the ear hole type hearing aid 15, the earphone intrusion prevention chip 1 can be attached by directly fitting the earphone 16 to a tube (made of rubber) 18 attached to the shell 17. . A holder for attaching the earwax intrusion prevention chip 1 can be separately prepared, or the shape of the sound output port of the shell 17 can be made such that the earwax intrusion prevention chip 1 is directly held.
耳垢侵入防止チップ1を耳あな型補聴器15に装着すると、溝7とシェル17の先端面でトンネル20が形成され、イヤホン16から出力された音が、正面の音出力口19の他にトンネル20を経由して放出される。また、溝7を複数設けておけば、イヤホン16から出力された音を放出するトンネル20が複数形成されるので、音を放出するための音出力口19及びトンネル20からなる音口のすべてが塞がってしまう可能性が少なくなる。耳垢は耳垢侵入防止チップ1の表面に留まり易いので、表面をブラシで掃除するなど、簡易な清掃でほとんどの耳垢を除去することができる。 When the earwax intrusion prevention chip 1 is attached to the ear hole type hearing aid 15, a tunnel 20 is formed by the groove 7 and the front end surface of the shell 17, and the sound output from the earphone 16 is transmitted to the tunnel 20 in addition to the sound output port 19 on the front. Is released via. If a plurality of grooves 7 are provided, a plurality of tunnels 20 for emitting sound output from the earphone 16 are formed, so that all of the sound outlets 19 including the sound output port 19 and the tunnel 20 for emitting sound can be obtained. The possibility of being blocked is reduced. Since the earwax tends to stay on the surface of the earwax intrusion prevention chip 1, most earwax can be removed by simple cleaning such as cleaning the surface with a brush.
耳垢侵入防止チップ1の変形例としては、図6(a)に示すように、鍔部4に形成する溝7の数は2つに限らず、4つでもよい。スペースが許す限りいくつにしてもよい。溝7が多ければ多いほど、耳垢が耳垢侵入防止チップ1に付着しても、音を放出する通路9が確保され易くなる。また、溝7構造に比べると金型加工は難しくなるが、図6(b)に示すように、鍔部4の開口部3と同方向に貫通孔27を複数設け、各貫通孔27と音導部2の壁部に開けられた貫通孔8で、鍔部4の外側と音導部2の内側を連通する通路9を構成することもできる。 As a modification of the earwax intrusion prevention chip 1, as shown in FIG. 6A, the number of grooves 7 formed in the heel part 4 is not limited to two, but may be four. Any number of spaces are allowed. The more grooves 7, the easier it is to secure a passage 9 that emits sound even when ear wax adheres to the ear wax intrusion prevention chip 1. In addition, although it is difficult to mold as compared with the groove 7 structure, as shown in FIG. 6 (b), a plurality of through holes 27 are provided in the same direction as the opening 3 of the flange 4, and each through hole 27 and the sound are processed. A passage 9 that communicates the outside of the flange portion 4 and the inside of the sound guide portion 2 with the through hole 8 opened in the wall portion of the guide portion 2 can also be configured.
本発明の耳垢侵入防止チップを耳あな型補聴器の音出力口に装着することにより、音が全く出力されないことを少なくしつつ、イヤホンに耳垢が落ち込む可能性を低くすることができる。仮に耳垢侵入防止チップの鍔部の開口部及び全ての通路に耳垢が詰まったとしても、耳垢侵入防止チップを容易に交換することができるので、より快適な耳あな型補聴器を提供することができる。 By attaching the earwax intrusion prevention chip of the present invention to the sound output port of the earphone type hearing aid, it is possible to reduce the possibility that the earphone falls into the earphone while reducing the fact that no sound is output. Even if the earwax is clogged in the opening of the buttocks and all the passages of the earwax intrusion prevention chip, the earwax intrusion prevention chip can be easily replaced, so that a more comfortable earphone type hearing aid can be provided. .
