The second housing 12 is coupled to the first housing after the driver unit 13 is accommodated therein. Therefore, the first housing 11, the second housing 12, and the ear pad 15 are integrated.

The cable lead-out portion 17 serves as an input terminal, and an electric signal input through the cable 5 is supplied to the driver unit 13. The driver unit 13 generates a sound corresponding to the electric signal supplied by the cable 5. This sound is sent to the ear canal through the sound guide 16. Thus, the user of the earphone can hear a sound corresponding to the electric signal input through the cable 5.

On the other hand, a ring 21 is provided inside the holding member 20. On the ring 21, an annular stopper 30 made of resin is provided. The ring 21 and the stopper 30 are attached to the screw holes of the first housing 11 by screws 40. And the housing 20 is attached to the outer side of these members. Specifically, the housing 20 is connected to the ring 21.

With this configuration, the ring 21 is sandwiched and fixed between the housing 11 and the stopper 30. The stopper 30 is a resin and holds the ring 21 in a rotatable state while applying an appropriate pressure to the ring 21. Since the ring 21 and the housing 20 are connected and integrated, the holding member 20 can rotate with respect to the housing 10 together with the ring 21. That is, the first housing 11, the second housing 12, and the ear pad 15 integrated portion and the holding member 20 and the ring 21 integrated portion are connected by the screw 40 in a relatively rotatable state. The

FIG. 5A shows the first housing 11 and the ring 21. An annular convex portion 11 a formed on the first housing 11 is inserted into the ring 21. Further, a protrusion 11 b is formed on the periphery of the convex portion 11 a of the first housing 11. The protrusion 11b prevents a further rotation of the ring 21 by hitting a part of the ring 21. Specifically, the protrusions 11b are provided at positions corresponding to both ends of a range in which the housing 10 and the holding member 20 can relatively rotate, and the housing 10 and the holding member 20 are hooked to the hanging state of the earphone 1. Allow rotation between states.

The ring 21 has an annular convex portion 21a and an arc-shaped step portion 21b formed by cutting out a part of the annular convex portion 21a. Further, a pair of convex portions 21c are provided near both ends of the arc-shaped step portion 21b, and a concave portion 21d is formed between the convex portion 21c and the end surface of the annular convex portion 21a adjacent thereto. Yes.

FIG. 5 (B) shows the joint between the ring 21 and the stopper 30. A convex portion 21c is formed on the arc-shaped step portion 21b of the ring 21, and a concave portion 21d is formed between the convex portion 21c and the end surface 21e of the convex portion 21a adjacent thereto.

The stopper 30 is fixed on the ring 21 with a screw 40. A resin spring 31 is formed on a part of the circumference of the stopper 30. When the ring 21 is rotated relative to the stopper 30, the resin spring 31 moves on the step portion 21 b of the ring 21. Convex portions 21c are provided at both ends of the stepped portion 21b. When the resin spring 31 gets over the convex portion 21c, a certain resistance is generated, and then the resin spring 31 gets over the convex portion 21c and enters the concave portion 21d and is held. The Therefore, when the user of the earphone rotates the holding member 20 with respect to the housing 10, a certain resistance is generated in the vicinity of both ends of the rotatable range, and then the holding member 20 is at one end of the rotatable range. Fixed. When the resin spring 31 gets over the convex portion 21c, the user of this earphone feels a so-called click feeling. That is, the resin spring 31 and the convex portion 21c constitute a click mechanism. When the resin spring 31 enters the recess 21d, the resin spring 31 is stabilized in the recess 21d, so that the rotation of the holding member 20 with respect to the housing 10 ends there. Therefore, when the user of the earphone feels a click feeling near both ends of the rotatable range when the holding member 20 is rotated with respect to the housing 10, the position is the end of the rotatable range. Can be recognized. Moreover, since the screw 40 is attached with such a strength that the resin spring 31 cannot run on the convex portion 21a, the holding member 20 cannot be further increased. Therefore, relative rotation between the housing 10 and the holding member 20 is limited between both ends of the stepped portion 21b.

As described above, in the earphone of the embodiment, the holding member 20 for holding the housing 10 on the concha is provided, and the holding member 20 is stable to the concha in both the hanging state and the ear-hanging state. The earphone is securely attached to the ear. In addition, since the cable 5 is attached to the housing 10 between the ear hole and the holding member 20, the earphone can be reliably attached to the ear in both the hanging state and the ear-hanging state.

Also, since the user of this earphone can obtain a click feeling near the end of the relative rotatable range of the housing 10 and the holding member 20, it is possible to grasp the rotational position of both. That is, when the user of the earphone switches between the hanging state and the ear-hanging state, the user can rotate one of the housing 10 and the holding member 20 relative to the other to obtain a click feeling. You can end the rotation with.
