  In the figure, reference numeral 1 denotes a headphone according to the present embodiment, which has a main body 10 as a headphone main body and a headband 80. The main body 10 is a small sound generator that is mounted on and used by the user's pinna and the periphery thereof, is driven by a sound signal that is an electrical signal, and reproduces the sound signal. The headband 80 is made of an elastic material and straddles over the user's head.

  The headphone 1 is a stereo headphone, and there are two main bodies 10 which are respectively attached to both ends of the headband 80. Both have substantially the same configuration, and a cable 91 is connected thereto. For the sake of convenience, only one main body 10 to which the cable 91 is connected is shown, and the other main body 10 is not shown in the figure. .

  The main body 10 includes a housing 11 that houses a speaker unit (not shown) that reproduces an audio signal to generate sound, and an ear pad 71 that is attached to the front surface of the housing 11. The housing 11 is made of, for example, a resin such as a synthetic resin, but may be made of a metal such as aluminum, steel, or copper, or may be made of a composite material obtained by combining resin, carbon, metal, or the like. May be. Further, since the ear pad 71 is a member that comes into contact with the user's auricle and the periphery thereof, it is desirable that the ear pad 71 is made of a material having flexibility and elasticity such as a resin foam and a soft resin. Furthermore, the cable 91 has one end connected to one main body 10 and the other end (not shown) connected to an external device such as a music player, television, radio, video deck, etc. Thus, the speaker unit is energized, whereby the acoustic signal from the external device is transmitted to the speaker unit.

  In the present embodiment, the expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the headphone 1 and its components are absolute. However, the headphone 1 and its parts are suitable for the posture shown in the figure. However, when the headphone 1 and its parts are changed in posture, the posture changes.

  The main body 10 is slidably attached to both ends of the headband 80 via the slider portion 81, and the user slides the main body 10 with respect to the end of the headband 80, thereby The contact position of the ear pad 71 with respect to the auricle can be adjusted. The slider portion 81 includes a slide holding portion 82 fixed to the end portion of the headband 80 and a slide rod 83 as a main body connecting member having a lower end detachably attached to the main body 10.

  The slide holding unit 82 includes a well-known slide holding mechanism (not shown), and by the action of the slide holding mechanism, the slide rod 83 having the main body 10 attached to the lower end is held so that it cannot slide during normal use of the headphones 1. At the same time, when the user moves the main body 10 up and down with respect to the end portion of the headband 80 using fingers or the like, the main body 10 is slidably held. In other words, the slide holding mechanism is applied to the slide holding portion 82 when the sliding direction applied to the slide rod 83, that is, the axial direction of the slide rod 83 and the substantially vertical force is smaller than a predetermined value. When the slide rod 83 is not allowed to slide and the force applied to the slide rod 83 is equal to or greater than a predetermined value, the slide rod 83 is allowed to slide with respect to the slide holding portion 82. Since the slide holding mechanism is a well-known one, its description is omitted.

  A frame member 12 is attached to the outside of the main body 10, and a lower end of the slide rod 83 is detachably attached to a connecting portion 13 formed on the frame member 12. The frame member 12 is an arc-shaped member extending along a range of about half of the outer peripheral surface of the main body 10, and both ends thereof are pivotally attached to the main body 10. Accordingly, the main body 10 and the ear pad 71 can be inclined in the left-right direction in FIGS. 1A and 1C with respect to the slide rod 83, and the ear pad 71 can be appropriately applied to the surface of the head side portion of the user. Abutment is possible.

  In the present embodiment, a plug 51 as a first connector is attached to the lower end of the slide rod 83 as shown in FIGS. The plug 51 is a substantially cylindrical member that extends in the axial direction of the slide rod 83, and includes a flange portion 53 that protrudes outward in the radial direction and is formed near the middle in the axial direction. The upper side of the flange portion 53 is inserted into and fixed to a lower end portion of a hole portion 83a formed inside the slide rod 83. Below the flange portion 53 is a male terminal 52 as a first terminal, and the surface of the male terminal 52 is divided into a plurality of (three in the example shown in the figure) sections in the axial direction. The first contact portion 52a, the second contact portion 52b, and the third contact portion 52c, respectively. In addition, the number of the said divisions does not necessarily need to be 3, and can be changed arbitrarily. In addition, an insulator is interposed at the boundary between adjacent sections, and the sections are insulated from each other.

  A connecting cord 55 is disposed in the hole 83 a of the slide rod 83. The connecting cord 55 includes at least the number of the conductive wires of the section, and one end of each conductive line passes through a cavity (not shown) in the plug 51, and the first contact portion 52a and the first contact section as the section. The second contact portion 52b and the third contact portion 52c are electrically connected. In addition, one end of each conductive wire is connected to the other slide rod 83 connected to the other end (not shown) of the headband 80, the first contact portion 52a, the second contact portion 52b, and the third contact portion of the other plug 51. It is electrically connected to the contact part 52c. In this case, the connecting cord 55 is wired along the headband 80, for example, and portions near both ends thereof are inserted into the holes 83a of both slide rods 83.

  Further, on the outer peripheral surface in the vicinity of the lower end of the slide rod 83, there is formed a connection projection 85 having a shape similar to the flange portion 53 of the plug 51 and protruding outward in the radial direction. It should be noted that the protruding amount of the connecting protrusion 85 outward in the radial direction is set to be larger than the protruding amount of the flange portion 53 outward in the radial direction.

  On the other hand, a hollow fitting recess 15 as a second connector for accommodating the male terminal 52 of the plug 51 is formed inside the connecting portion 13, and the slide is formed above the fitting recess 15. A cylindrical insertion opening 14 into which the lower end portion of the rod 83 is inserted is formed. The insertion opening 14 has an upper end that opens to the upper surface of the connecting portion 13, and a lower end that opens to the upper surface of the fitting recess 15 and communicates with the fitting recess 15. An insulating wall member 16 made of an insulating material is disposed on the inner surface of the fitting recess 15. Further, the inner diameter of the insertion opening 14 is set to be larger than the outer diameter of the lower ends of the slide rod 83 and the flange portion 53 and smaller than the outer diameter of the connecting projection 85.

  A female terminal 62 as a second terminal protruding from the side wall is disposed in the fitting recess 15. The female terminal 62 includes a first protrusion 62a, a second protrusion 62b, and a third protrusion 62c as a plurality of protrusions (three in the example shown in the figure). It is an elastically deformable member and is arranged side by side in the insertion and extraction directions of the male terminal 52. In addition, the number of the said protrusion part does not necessarily need to be 3, and can change arbitrarily. Thereby, the plug 51 as the first connector can be releasably fitted with the fitting recess 15 as the second connector.

  A plurality of connection wires 65 are disposed inside the frame member 12 and the connecting portion 13. One end of each connecting wire 65 is electrically connected to the first projecting portion 62a, the second projecting portion 62b, and the third projecting portion 62c, and the other end of each connecting wire 65 is electrically connected to the speaker unit. Connected. The connecting wire 65 is not necessarily disposed inside the frame member 12 and the connecting portion 13, and may be disposed outside the frame member 12 and the connecting portion 13.

  A connecting recess 14 b that engages with the connecting protrusion 85 of the slide rod 83 is formed on the peripheral wall of the insertion opening 14. The connecting concave portion 14b is a ring-shaped concave groove formed so as to surround the side surface of the insertion opening 14 in the circumferential direction, and is formed so as to accommodate the connecting protrusion 85.

  In addition, one or more slit-shaped separation grooves 14 a extending in the vertical direction are formed in a portion forming the peripheral wall of the insertion opening 14 in the connecting portion 13. The insertion opening 14 opens on the side surface of the connecting portion 13 by the separation groove 14a. Thereby, since the said insertion opening part 14 becomes elastically diameter-expandable and diameter-reducible, the slide rod 83 as a main body connection member is connected with the connection part 13 so that attachment or detachment is possible.

  When attaching the slide rod 83 to the main body 10, the user of the headphone 1 first has a frame member in which the lower end of the slide rod 83 is attached to the main body 10 as shown in FIGS. 2 and 3 (b). The central axis of the plug 51 located at the lower end of the slide rod 83 and the central axis of the insertion opening 14 formed in the connecting part 13 are aligned so as to be opposed to the twelve connecting parts 13.

  In this state, the slide rod 83 and / or the connecting portion 13 are moved in a direction approaching the other side, and the plug 51 is inserted into the insertion opening 14. Then, the male terminal 52 of the plug 51 enters the fitting recess 15 through the insertion opening 14. Further, the lower end of the slide rod 83 enters the insertion opening 14. In this case, when the connection protrusion 85 passes above the connection recess 14b in the insertion opening 14, the insertion opening 14 is elastically expanded in diameter, and the connection protrusion 85 reaches the position of the connection recess 14b. The insertion opening 14 is elastically reduced in diameter, and the connecting protrusion 85 is accommodated in the connecting recess 14b.

  When the attachment of the slide rod 83 to the main body 10 is completed, as shown in FIG. 3A, the first projecting portion 62a, the second projecting portion 62b, and the third projecting portion disposed in the fitting recess 15 are provided. The protrusion 62c elastically contacts the first contact portion 52a, the second contact portion 52b, and the third contact portion 52c of the plug 51, respectively. As a result, the plug 51 as the first connector is engaged with the fitting recess 15 as the second connector, and each connecting wire 65 is electrically connected to the corresponding conductive wire of the connecting cord 55. Therefore, in the state where the slide rods 83 at both ends of the headband 80 are attached to both the left and right main bodies 10, the speaker units of both main bodies 10 are electrically connected to each other. The signal is transmitted to the speaker units of both main bodies 10 via a cable 91 connected to one main body 10.

  Further, in a state where the mounting of the slide rod 83 to the main body 10 is completed, the insertion opening 14 is elastically reduced in diameter, and the connecting projection 85 is accommodated in the connecting recess 14b and is thus engaged. The unit 13 holds the slide rod 83 so that it cannot be pulled out during normal use of the headphones 1. On the other hand, when the user moves the slide rod 83 upward with respect to the connecting portion 13 by using a finger or the like, the insertion opening 14 is elastically expanded in diameter, and the connecting projection 85 extends from the connecting recess 14b. The lower end of the slide rod 83 is extracted from the insertion opening 14. In other words, the connecting portion 13 is inserted into and removed from the insertion opening 14 when the insertion and extraction directions applied to the slide rod 83, that is, the axial direction of the slide rod 83 and the substantially vertical force is smaller than a predetermined value. When the lower end of the slide rod 83 is not permitted to be inserted and removed, and the force applied to the slide rod 83 is greater than or equal to a predetermined value, the lower end of the slide rod 83 is allowed to be inserted into and removed from the insertion opening 14. It has become.
