Description

  The present invention relates to a stereo earphone with a cord winder provided with a cord winder capable of winding and storing an earphone cord.

  Conventionally, a cord reel capable of pulling out a required length of the earphone cord by attaching a winding function of the earphone cord and storing an excess cord in a compact manner has been well known.

JP-A-11-55778

  However, although the cord reel of the prior art has a function of storing the earphone cord, it is fixed at an intermediate position of the earphone cord when the earphone is used, and the cord reel greatly shakes during walking or the earphone comes off the ear. In some cases, the wearing feeling of the earphone is uncomfortable.

  Therefore, as a means for solving the above problems, a stereo earphone with a cord winder according to the utility model of the present application is provided with an earphone at the distal end and a plug shaft body at the proximal end, and one end surface of the earphone cord. A winding body formed of a cylindrical body shaft formed on the bonding surface and a substrate formed by expanding radially outward from the other end of the body shaft, and bonded and fixed to the bonding surface A cord winder comprising two members with a flat plate-like support plate, and a slit formed by cutting from the bonding surface toward the other end direction along the central axis in the trunk shaft; The earphone cord is inserted into the slit, and the cord winder is slidable along the earphone cord.

  The slit is formed so as to be opened in the axial direction on the bonding surface of the trunk shaft before the support plate portion is bonded and fixed to the trunk shaft. Therefore, even in the case of an earphone cord having an earphone having a size larger than the radial width of the slit and a plug shaft body, the earphone cord is inserted into the slit from the direction of the adhesive surface before the support plate portion is bonded and fixed. Thus, the earphone cord can be provided with a cord winder. Then, the opening portion in the axial direction of the slit can be closed by adhering and fixing the support plate portion to the bonding surface formed on one end surface of the trunk shaft, and the cord winder falls off from the earphone cord in the axial direction. There is no.

  Moreover, since the slit is formed by conducting the trunk shaft in the radial direction, the cord winder can be freely slid along the earphone cord during use of the stereo earphone. Thereby, the user can adjust the cord winder to an appropriate position that does not get in the way when walking.

  According to the present invention, the cord winder can be positioned at any location along the earphone cord so that the position of the cord winder can be easily adjusted, and the stereo earphone is worn on the ear. The feeling of wearing the stereo earphone does not become uncomfortable when the cord winder is greatly shaken even during walking in a walking state.

FIG. 3 is a perspective view of a stereo earphone with a cord winder in a state in which the earphone cord is wound around a trunk shaft and the earphone cord is wound and stored.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the stereo earphone 1 with a cord winder includes an earphone cord 4 that includes an earphone 2 at a distal end portion and a plug shaft body 3 at a proximal end portion, and a cord winder 5. The cord winder 5 includes a cylindrical body shaft 6 and a winding body portion 8 including a substrate 7 formed by radially expanding from the other end of the body shaft 6 in a radially outward direction. It consists of two members, a flat plate-like support plate portion 10 that is bonded and fixed to an adhesive surface 9 formed on one end surface.

  The body shaft 6 is provided with a slit 11 formed by being cut from the central portion of the bonding surface 9 along the center axis toward the other end. Further, the slit 11 is formed in the radial direction of the body shaft 6. Conducted. Therefore, the earphone cord 4 can be inserted in the slit 11 in the radial direction as shown in FIG.

  In the cord winder 5, the slit 11 is closed from one end direction when the support plate portion 10 is bonded and fixed to the bonding surface 9 of the barrel shaft 6, and the slit is cut into the barrel shaft 6 from the front as shown in FIG. 11 can be confirmed in the radial direction. On the other hand, as shown in FIG. 3, the through hole cannot be confirmed in the body shaft 6 from the right side view. In addition, the slit 11 is formed in the radial direction of the trunk shaft 6 by looking at the AA sectional view shown in FIG. 5, the BB sectional view shown in FIG. 6, and the CC sectional view shown in FIG. It can be seen that it is formed only through.

  In the present embodiment, when the cord winder 5 is viewed from the plane direction as shown in FIG. 4, the support plate portion 10 is formed in a circular flat plate shape. This has the advantage that it is easy to perform a winding operation when the earphone cord 4 is wound around the trunk shaft 6. As shown in FIG. 7, in the present embodiment, the substrate 7 is also formed in the same circular flat plate shape as the support plate portion 10. Since the support plate portion 10 and the substrate 7 have the same circular flat plate shape, the cord winder 5 can be easily rotated by hand, and the earphone cord 4 can be wound more efficiently.

  As described above, the earphone cord 4 is attached to the cord winder 5 by being inserted into the slit 11. Therefore, the cord winder 5 can be freely slid along the cord in a state where the earphone cord 4 is extended as shown in FIGS. Since the cord winder 5 is freely slidable along the earphone cord 4, the cord winder 5 can be positioned at an arbitrary position along the earphone cord 4. The position of the tool 5 can be adjusted, and even when walking with the stereo earphone worn on the ear, the cord winder 5 shakes greatly, etc., and the wearing feeling of the stereo earphone is uncomfortable. Never become.

  When the stereo earphone 1 with the cord winder is not used, the earphone cord 4 can be compactly stored by winding the earphone cord 4 around the circumferential surface of the trunk shaft 6 as shown in FIG.
