Description

本考案は耳栓の分野に関し、特に耐圧縮性を有し、高い構造安定性を有する耳栓に関する。   The present invention relates to the field of earplugs, and more particularly to earplugs that are compression resistant and have high structural stability.

現在、イヤホーンはもはや人々の音楽鑑賞に欠かせない物となっている。イヤホーンは大きく耳マスク式と、カナール式と、耳プラグ式とに分けられる。イヤホーンはそれぞれ耳に固定する方式も一様ではない。カナール式イヤホーンは、貫通孔を有する耳栓を別途取り付けることで、イヤホーンが貫通孔のある耳栓を介して、外耳道に固定されると同時に、音声伝達と、外部音声を遮る効果がある。   Today, earphones are no longer necessary for people to enjoy music. Earphones are roughly classified into ear mask type, canal type and ear plug type. The method of fixing earphones to the ears is not uniform. The Canal type earphone is separately attached with an earplug having a through hole, so that the earphone is fixed to the external auditory canal via an earplug having a through hole, and at the same time, has an effect of blocking sound transmission and external sound.

図１の公知技術の耳栓の態様図を参照する。図に示すように、従来の耳栓１は、中空状のチューブ体１１と外部フード体１２とを含み、中空状のチューブ体１１は音声入力端と音声出力端とを有し、外部フード体１２が中空状のチューブ体１１の音声出力端の最上部の外側から後方に延設され、フード状の弾性体を形成する。しかし、この種の耳栓１を実際に使用するとき、人によって外耳道の径が違うため、異なるサイズの耳栓１を使用者で選択して使用する必要があった。すなわち、耳栓１を製造するときに、外部フード体１２の大きさを調整しなければ、外耳道の径の大きさに合わせることができない。よって、製造コストが高くなるとともに、使用者もその都度試着して、自分に合う耳栓１を選択する必要があり、極めて不便である。さらに、従来型の耳栓１は、軟性部材からすべて一体的に成形されており、使用時間が経過すると、または使用が一定回数に達すると、耳栓１は変形の恐れがある。特に固定構造を有しない外部フード体１２部分では、元々有する外部音声の遮断効果が低下する。   Referring to the prior art earplug embodiment of FIG. As shown in the figure, a conventional earplug 1 includes a hollow tube body 11 and an external hood body 12, and the hollow tube body 11 has an audio input end and an audio output end, and the external hood body. 12 extends rearward from the outermost part of the audio output end of the hollow tube body 11 to form a hood-like elastic body. However, when this type of earplug 1 is actually used, since the diameter of the external auditory canal differs depending on the person, it is necessary to select and use an earplug 1 of a different size. In other words, when the earplug 1 is manufactured, the size of the external ear canal 12 cannot be adjusted unless the size of the external hood body 12 is adjusted. Therefore, the manufacturing cost becomes high, and the user also has to try on each time and select the earplug 1 that suits him / her, which is very inconvenient. Furthermore, the conventional earplugs 1 are all integrally formed from a soft member, and the earplugs 1 may be deformed when the usage time elapses or when the usage reaches a certain number of times. In particular, in the external hood body 12 portion that does not have a fixing structure, the external sound blocking effect that is originally provided is reduced.

この点について、本考案者は完備されていないところを鋭意研究し、係る産業において長年蓄積された経験をもとに、本案の耳栓を考案し、前述した公知技術の欠点の改善を図ろうとするものである。   In this regard, the inventor has eagerly studied where it has not been completed, and devised the earplug of the present plan based on the experience accumulated for many years in the industry, and tried to improve the above-mentioned drawbacks of the known technology. To do.

本考案の目的の一つは、様々な外耳道の径及び形状に適合できることに加え、充分な構造安定性を有する、変形しにくい耳栓を提供することである。   One of the objects of the present invention is to provide an earplug that is adaptable to various ear canal diameters and shapes, and has sufficient structural stability and is not easily deformed.

前述の目的を達成するため、本考案により、カナール型イヤホーンに取り付ける耳栓を提供する。本考案の耳栓は、固定部と封止部とを備え、固定部の一端は耳内部に差し込まれ、表面に第１穴部を有し、他端に内側に延伸する凹溝を形成し、凹溝が第１穴部と連通していて、凹溝が第１穴部に対応する箇所に固定部と一体成形されたチューブ体を有する。チューブ体は、固定部の一端より耳内部で固定部の他端まで延伸して設けられ、チューブ体をイヤホーンの音声出力部と繋ぐことで、音声がチューブ体を介して耳内部に伝えられる。封止部はチューブ体と接続しており、封止部とチューブ体との接続部にチューブ体と連通する第２穴部を有し、封止部によって凹溝が封止され、凹溝の内部には空気が充満しており、凹溝にリング状の弾性戻り空間が形成される。   In order to achieve the above-mentioned object, according to the present invention, an earplug to be attached to a canal type earphone is provided. The earplug of the present invention includes a fixing portion and a sealing portion, and one end of the fixing portion is inserted into the ear, has a first hole on the surface, and forms a concave groove extending inward at the other end. The concave groove communicates with the first hole portion, and the concave groove has a tube body integrally formed with the fixed portion at a position corresponding to the first hole portion. The tube body is provided so as to extend from one end of the fixing portion to the other end of the fixing portion inside the ear, and the sound is transmitted to the inside of the ear via the tube body by connecting the tube body to the sound output portion of the earphone. The sealing portion is connected to the tube body, and the connection portion between the sealing portion and the tube body has a second hole portion that communicates with the tube body, and the concave groove is sealed by the sealing portion. The inside is filled with air, and a ring-shaped elastic return space is formed in the concave groove.

中でも、固定部は軟性部材から製造され、封止部は硬質部材から製造されることによって、封止部の構造安定性が強化され、イヤホーンの接続をより安定させることができる。   Among these, the fixing portion is manufactured from a soft member and the sealing portion is manufactured from a hard member, whereby the structural stability of the sealing portion is enhanced and the connection of the earphone can be further stabilized.

このようにして、本考案は、凹溝とチューブ体との対向位置によって形成される弾性戻り空間によって、耳栓を外耳道に差し込んだ後、凹溝に封止された空気によって、耳栓が圧縮された後、速やかに元の形状に戻され、耳栓を外耳道に固定する一方、弾性戻り空間を介して、固定部に充分な構造安定性が与えられ、しかも変形しにくい。本耳栓はまた、各種の外耳道の径及び形状に対応でき、構造的に安定するという長所を有する。   Thus, the present invention compresses the earplug by the air sealed in the concave groove after the earplug is inserted into the ear canal by the elastic return space formed by the facing position between the concave groove and the tube body. Then, it is quickly returned to its original shape and the earplug is fixed to the ear canal, while sufficient structural stability is given to the fixing portion via the elastic return space, and it is difficult to deform. The earplug also has the advantage of being structurally stable and adaptable to various external auditory canal diameters and shapes.

審査官の方々が本考案の内容のさらなる理解のため、下記の説明に図式を組み合わせて、参考にしていただきたい。   For further understanding of the contents of the present invention, examiners should refer to the following explanations by combining diagrams.

図２から図４、つまり、本考案の好ましい実施例による断面図と、取り付け状態を示す態様図と、外耳道に詰め込んだ状態を示す態様図とを参照する。図に示すように、本考案の耳栓２は、カナール式イヤホーン３に取り付けられ、固定部２１と封止部２２とを備える。固定部２１の一端は耳内部へ差し込まれ、表面に第１穴部２１１を有し、他端に内側に延伸する凹溝２１２を形成し、凹溝２１２が第１穴部２１１と連通していて、かつ、凹溝２１２が第１穴部２１１に対応する箇所に固定部２１と一体成形されたチューブ体２１３を有し、チューブ体２１３が固定部２１の一端より耳内部で固定部２１の他端まで延伸して設けられており、チューブ体２１３をイヤホーンの音声出力端と繋ぐことで音声がチューブ体２１３を介して、耳内部に伝えられる。また、封止部２２は固定部２１が凹溝２１２を設けた一端に設けられていて、かつ、チューブ体２１３と接続しており、封止部２２とチューブ体２１３との接続部にチューブ体２１３と連通する第２穴部２２１を有し、封止部２２によって凹溝２１２が封止され、凹溝２１２の内部には空気が充満しており、凹溝２１２にリング状の弾性戻り空間が形成される。   Please refer to FIG. 2 to FIG. 4, that is, a sectional view according to a preferred embodiment of the present invention, an aspect view showing an attached state, and an aspect view showing a state packed in the ear canal. As shown in the figure, the earplug 2 of the present invention is attached to a canal earphone 3 and includes a fixing portion 21 and a sealing portion 22. One end of the fixing portion 21 is inserted into the ear, has a first hole 211 on the surface, and forms a concave groove 212 extending inward at the other end. The concave groove 212 communicates with the first hole 211. In addition, the concave groove 212 has a tube body 213 integrally formed with the fixing portion 21 at a position corresponding to the first hole portion 211, and the tube body 213 is formed at one end of the fixing portion 21 inside the ear from the end of the fixing portion 21. Extending to the other end, the sound is transmitted to the inside of the ear through the tube body 213 by connecting the tube body 213 to the sound output end of the earphone. The sealing portion 22 is provided at one end where the fixing portion 21 is provided with the concave groove 212 and is connected to the tube body 213, and the tube body is connected to the connection portion between the sealing portion 22 and the tube body 213. 213 has a second hole part 221 communicating with the sealing part 22, the groove 212 is sealed by the sealing part 22, the inside of the groove 212 is filled with air, and the groove 212 has a ring-shaped elastic return space. Is formed.

凹溝２１２が封止部２２によって封止され、弾性戻り空間を形成し、耳栓２が外耳道に圧入された後、固定部２１は弾性戻り空間に充満した気圧により、より迅速に元の状態に戻ることができ、イヤホーン３は外耳道に固定される。すなわち、弾性戻り空間は気嚢のような効果を達成することができる。使用者の外耳道の形状や径の大小に拘らず、弾性戻り空間の気圧の拡張力によって、様々な外耳道に適用することができる。第４図を参照。さらに、本実施例において、固定部２１は軟性部材から製造されているのに対して、封止部２２は硬質部材から製造されている。よって、硬質の封止部２２によって、イヤホーン３との接続剛性が強化され、使用時間の経過によって、耳栓２とイヤホーン３とのつなぎ場所に変形が生じるのが避けられる。   After the concave groove 212 is sealed by the sealing portion 22 to form an elastic return space and the earplug 2 is press-fitted into the ear canal, the fixing portion 21 is more quickly restored to the original state by the atmospheric pressure filled in the elastic return space. The earphone 3 is fixed to the ear canal. That is, the elastic return space can achieve an effect like an air sac. Regardless of the shape and diameter of the user's external auditory canal, it can be applied to various external auditory canals by the pressure expansion force of the elastic return space. See FIG. Furthermore, in this embodiment, the fixing portion 21 is manufactured from a soft member, whereas the sealing portion 22 is manufactured from a hard member. Therefore, the rigid sealing portion 22 enhances the connection rigidity with the earphone 3, and it is possible to avoid the occurrence of deformation at the place where the earplug 2 and the earphone 3 are connected as the usage time elapses.

さらに、凹溝２１２は、空気が充填された後に封止されているので、固定部２１の構造の剛性強化の効果を達成できる。凹溝２１２に封入された気体は減少しないため、何回押されても、固定部２１は間違いなく元の状態に戻ることができる。よって、軟性部材からなる固定部２１が数回の押圧によって変更するという欠点を回避することができ、固定部２１は優れた構造剛性を有する。   Furthermore, since the concave groove 212 is sealed after being filled with air, the effect of enhancing the rigidity of the structure of the fixed portion 21 can be achieved. Since the gas sealed in the concave groove 212 does not decrease, the fixing portion 21 can definitely return to the original state no matter how many times it is pushed. Therefore, the fault that the fixing | fixed part 21 which consists of a soft member changes with several presses can be avoided, and the fixing | fixed part 21 has the outstanding structural rigidity.

前述した通り、本考案は、凹溝２１２内部の気体が漏れるのを防ぐために、封止部２２によって、凹溝２１２を封止するので、耳栓２をスムーズに耳内部に差し込むことができる。さらに、使用者の外耳道の径、大小、形状に拘らず、固定部２１が弾性戻り空間によって、外耳道に固定されるので、サイズが合わないために、耳栓２を交換する心配はない。さらに、封止部２２を設けることによって、耳栓２と、イヤホーン３との接続部に充分な構造剛性を持たせているので、使用時間の経過によって、耳栓２とイヤホーン３との接続部が変形し、使用者の着用に不快感を与える心配はない。   As described above, the present invention seals the concave groove 212 by the sealing portion 22 in order to prevent the gas inside the concave groove 212 from leaking, so that the earplug 2 can be smoothly inserted into the ear. Furthermore, regardless of the diameter, size, and shape of the user's external auditory canal, the fixing portion 21 is fixed to the external auditory canal by the elastic return space. Further, since the sealing portion 22 is provided, the connecting portion between the earplug 2 and the earphone 3 has a sufficient structural rigidity, so that the connecting portion between the earplug 2 and the earphone 3 can be used over time. There is no worry that it will be deformed and uncomfortable for the user.
