る等の問題があつた。 As shown in Figure 1, this type of behind-the-ear hearing aid has a hearing aid body 1 that houses an electroacoustic transducer, an amplifier, a battery, etc., and a hollow sound guide path that is curved to fit behind the ear. The ear hook member 2 is combined,
The hearing aid main body 1 is held on the outer rear side of the ear shell by the ear hook member 2. Furthermore, it is composed of a sound guide tube 4 having one end connected to the ear hook member 2 and an ear plug 3 made of soft synthetic resin connected to the other end. However, conventionally, as shown in FIG. 2, the sound guide tube 4 and the ear plug 3 are connected by an L-shaped coupling member 5 having a sound guide path 5a.
and earplugs 3 were combined. In conventional hearing aids with such a configuration, the angle of the earplug 3 with respect to the coupling member 5 is always constant, so it is convenient for hearing aid users to adjust the earplug 3 to follow the curve of their own external auditory canal. Proper insertion of the ear plugs is not always achievable, and even though the ear plugs 3 are made of soft synthetic resin, feedback still occurs due to imperfect fit between the ear plugs 3 and the external auditory canal. There was a problem with inviting people. In the first place, the degree of curvature of the human ear canal varies greatly from person to person, and the structure of a conventional behind-the-ear hearing aid in which the angle of the ear plug 3 with respect to the coupling member 5 is constant is designed to compensate for such individual differences. It can be said that there was a lack of consideration for the Users of behind-the-ear hearing aids with this conventional configuration often force the earplugs into the ear canal to prevent howling.
For this reason, the ear canal wall may block the sound hole of the ear plug, failing to achieve its purpose, or the ear plug may not fit properly into the ear canal, causing ear plugs to become dislodged due to jaw movements associated with conversation or eating. There were problems such as it falling out of the ear canal.
この考案は、以上の事情に鑑みてなされたもの
であり、補聴器本体から導出された導音チユーブ
ないしはこの導音チユーブに接続された結合部材
に対する耳せんの角度に自由度を与えることによ

することを目的とするものである。 This invention was made in view of the above circumstances, and by giving flexibility to the angle of the earplug with respect to the sound guide tube led out from the hearing aid body or the coupling member connected to the sound guide tube, it is possible to The purpose of this project is to provide a behind-the-ear hearing aid that solves the above problems.
以下、この考案を図面に示す実施例によつて説
明する。 This invention will be explained below with reference to embodiments shown in the drawings.
第３図はこの考案の第一の実施例であり、耳せ
ん３が結合するＬ字状の結合部材５の結合端５ｂ
を略球状に形成し、これに軟質合成樹脂でなる耳
せん３の結合部３ａを圧入結合した構成になるも
のである。なお、結合部３ａに結合端５ｂと適合
する略球状の凹部を形成することにより、結合部
材５と耳せん３との結合状態をより好適にするこ
とができる。また、結合端５ｂは多面体によつて
略球状としてもよい。 FIG. 3 shows the first embodiment of this invention, in which the connecting end 5b of the L-shaped connecting member 5 to which the ear plug 3 is connected.
is formed into a substantially spherical shape, and the connecting portion 3a of the earplug 3 made of soft synthetic resin is press-fitted thereto. Note that by forming a substantially spherical concave portion in the coupling portion 3a that fits the coupling end 5b, the coupling state between the coupling member 5 and the ear plug 3 can be made more suitable. Furthermore, the joint end 5b may be made of a polyhedron and may have a substantially spherical shape.
以上の構成により、結合部材５と耳せん３とは
略球状の結合端５ｂによつて自在結合を形成し、
したがつて、結合部材５に対する耳せん３の角度

可能としているので、前述の個人差による耳せん
の不適合の問題を解消することができる。 With the above configuration, the coupling member 5 and the ear plug 3 form a flexible coupling by the substantially spherical coupling end 5b,
Therefore, the angle of the ear plug 3 with respect to the coupling member 5 can be easily adjusted to fit the ear canal of the hearing aid user, and this adjustment allows for three-dimensional adjustment, so that it can be easily adjusted to fit the ear canal of the hearing aid user. It is possible to solve the problem of misfitting of earplugs.

である。いずれも同様の効果を奏する。 FIG. 5 shows a third embodiment of this invention, in which a substantially spherical connecting portion 3'a is formed at the end of the ear plug 3,
The connecting portion 5'b of the connecting member 5 is fitted and connected to the connecting portion 3'a. In addition, FIG. 6 shows the soft member 3b.
This is a fourth embodiment in which the ear plug 3 is formed by combining the hard member 3c with the hard member 3c, and the hard member 3c is formed with a substantially spherical joint 3'a, and the joint 5'b of the joint member 5 is formed with a substantially spherical joint 3'a. is connected to the connecting portion 3'a. Both have similar effects.
また、以上の実施例において耳せんをイヤモー
ルドと称する耳形耳せんとしても同様である。 Further, in the above embodiments, the earplugs may be ear-shaped earplugs called earmolds.
