Description

  The present invention relates to an apparatus for winding a cable for headphones.

  In general, headphones are mainly used for users to listen to music and the like without being disturbed by the users, but users often use headphones outside the home. In other words, headphones are used when listening to music while walking along an alley or traveling on a subway or bus.

  In this way, in order for the user to use the headphones, it is necessary to connect the headphones to the sound output device, but in order to connect the headphones and the sound output device, a cable having a predetermined length is used. Is almost. However, when the sound output device and the headphones are connected by wire, the movement of the user becomes inconvenient due to the cable, so the sound output device and the headphones are wirelessly connected using short-range wireless communication. Headphones with a short-range wireless communication module that can be connected to the market are also on the market.

  Of course, the method of outputting music or the like to the headphones through short-range wireless communication is inevitably inferior in sound quality to the method of transmitting sound signals by wire and outputting sound through the headphones. This is because a signal is transmitted by wireless communication, so that there is a loss of an acoustic signal or the like as compared with a wired connection. For this reason, many headphones are currently on the market.

  As mentioned above, when using wired headphones, the cable causes the user's movement more difficult when listening to music etc., and how to handle the headphone cable when the headphones are not used any more Is a problem. In most cases, it is common to collect the headphone housings on both the left and right sides in one place, and then wrap the cables on top of them and store them, or wrap the cables using a headphone manufacturer or a separate structure. It is common to leave.

  In order to solve such a problem, for headphones with a cord winder (hereinafter referred to as prior art), a technique for storing a cable by winding the cable of the headphone inside the housing has been proposed (for example, , See Patent Document 1 below). According to this document, this technique is a technique for storing a cable in the housing so that the cable is caught in the housing when a plug connected to an external sound output device is inserted into the housing.

  However, in the prior art, in order for a user to pull out a cable by a desired length, the cable is pulled out by a desired length while the cable is completely wound in the housing. In other words, in order to adjust the length of the cable while the entire cable is pulled out, it is necessary to reduce the length of the cable pulled out by inserting the plug into the housing. Since the cable is wound inside the housing from the moment when the cable is inserted into the housing, the user must quickly remove the plug from the housing when the desired length is reached.

JP 2002-10385

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wind-up device for headphones capable of adjusting the length of a cable more conveniently and freely.

  In order to achieve the above object, a wind-up device for headphones according to one aspect of the present invention includes a housing in which an accommodation space is provided and which can accommodate a transducer that converts an electrical signal into an acoustic signal; A plug connected to the external device is formed on one side, a cable for passing an electrical signal sent from the external device to the transducer side, and a cable that is housed in the housing space and wound around the cable. A reel case that is removably rotated; and a control unit that accommodates the plug and operates together with the accommodated plug to control the presence or absence of rotation of the reel case.

  The control means is attached to the housing and has the plug inserted therein, and controls the first lever that can rotate with the inserted plug, and the presence or absence of rotation of the reel case by the rotation of the first lever. And a second lever for performing an operation for the purpose.

  The second lever further includes a first elastic body having elasticity in the second lever so that the reel case can be prevented from rotating.

  The first lever rotates with reference to an axis that forms an angle of 0 ° to 90 ° with the longitudinal axis of the first lever.

  The first lever rotates with a longitudinal axis of the first lever as a reference.

  The first lever moves in one side direction and then rotates with a longitudinal axis of the first lever as a reference.

  It further comprises a second elastic body that applies a restoring force to the first lever in a direction that prevents movement or rotation of the first lever.

  According to the present invention, it is possible to recognize that the cable is wound inside the housing by performing the operation of inserting the plug into the plug lever attached to the housing and the operation of rotating the plug inserted into the plug lever. Thus, the user can easily adjust the length of the cable as desired.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but detailed descriptions of well-known technical parts will be omitted for the sake of simplicity.

<First Embodiment>
The headphone winding device 100 corresponding to the first embodiment of the present invention includes a housing 10, a cable 20, a base plate 110, a reel case 120, a first lever 130, and a second lever 140. , A rotating elastic body (not shown) and a restoring elastic body 150 are provided. A headphone winding device 100 corresponding to the first embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

  The housing 10 has an accommodation space in which a large number of components can be accommodated. The accommodation space has a base plate 110, a reel case 120, a rotating elastic body, a first lever 130, and a second lever 140. The restoring elastic body 150 is accommodated. In the housing space of the housing 10, it is possible to house a transducer that converts an input electrical signal into sound and outputs the sound.

  In the cable 20, a plug 30 that can be connected to the external device is formed on one side so that an electrical signal is input from the external device to the transducer accommodated in the housing 10. The electrical signal is passed to the transducer. At this time, as the plug 30, a one-letter shape may be used, or an L-shaped one may be used.

  The base plate 110 is coupled to the housing 10 while being accommodated in the accommodating space of the housing 10, and provides a shaft for rotating the reel case 120.

  The reel case 120 is configured to be coupled to the base plate 110 so as to be rotatable by 360 ° in the base plate 110 and to wind the cable 20.

  The rotational elastic body is preferably located between the reel case 120 and the base plate 110 and continuously provides elasticity to the reel case 120 for the rotation of the reel case 120. Examples of the rotational elastic body include a mainspring and the like. Is preferably used.

  Since the reel case 120 is elastically rotated by the rotational elastic body in this way, it is necessary to prevent the reel case 120 from rotating by using a separate structure. One or more locking portions 122 are formed at the edge, and the second lever 140 is locked to the locking portion 122 to prevent the reel case 120 from rotating.

  The first lever 130 is formed with an insertion portion 132 into which the plug 30 is inserted on one side, and a rotation shaft portion 134 of the first lever 130 for rotating the first lever 130 on the other side. Although formed, the rotating shaft portion 134 of the first lever 130 is coupled to the base plate 110. The first lever 130 is provided with an operating portion 136 for operating the second lever 140 on one side of the insertion portion 132, and the first lever 130 is a rotating shaft portion of the first lever 130. An elastic portion 138 is provided to provide a restoring force against rotation when rotated with respect to 134, and the elastic portion 138 is locked to a fixed shaft 112 formed on the base plate 110 and is fixed to the first lever 130. Provides restoring force against rotation. At this time, since the first lever 130 is formed of a synthetic resin such as plastic having a predetermined elasticity or a metal, the elastic portion 138 is not formed of a spring or the like as shown in FIG. The first lever 130 provides elasticity to the first lever 130 while being locked to the fixed shaft 112 of the base plate 110, and the first lever 130 provides a restoring force against the rotation of the reel case 120 toward the center side.

  The second lever 140 is provided to prevent the reel case 120 from rotating due to the rotational force received by the reel case 120, and one end of the second lever 140 is attached to the locking portion 122 formed at the edge of the reel case 120. The reel case 120 is prevented from rotating by being locked on the side. Then, the other side of the second lever 140 abuts on the operating portion 136 of the first lever 130, and the other side of the second lever 140 is rotated by the operation of the operating portion 136 of the first lever 130. The rotation shaft 142 of the second lever 140 is disposed in the middle of the second lever 140. At this time, the rotating shaft 142 of the second lever 140 is coupled to the base plate 110 in the same manner as the rotating shaft 134 of the first lever 130.

  The restoring elastic body 150 is connected to the base plate 110 on one side, and the other side is connected to the second lever 140 so as to prevent the reel case 120 from rotating. I will provide a. That is, the restoring elastic body 150 is formed of a spring or the like, and when the one side of the second lever 140 moves away from the center direction of the reel case 120 so as not to be locked to the locking portion 122 of the reel case 120, A restoring force is provided to one side of the lever 140 so that one side of the second lever 140 is locked to the locking portion 122 of the reel case 120.

  Next, based on FIG. 3, the operation of the wind-up device 100 for headphones corresponding to the first embodiment of the present invention having the above-described configuration will be described.

  As shown in FIGS. 3A and 3B, when the plug 30 is inserted into the insertion portion 132 of the first lever 130, the first lever 130 is moved as shown in FIG. When the inside of the housing 10 is rotated by a predetermined angle (about 5 to 15 °) with respect to the rotation shaft portion 134 of the first lever 130, the operation portion 136 of the first lever 130 is moved to the other side of the second lever 140. Press the side. At this time, a restoring force is applied by the elastic portion 138 of the first lever 130 so that the first lever 130 returns to the position before being rotated.

  When the other side of the second lever 140 is pressed by a predetermined amount by the operating portion 136 of the first lever 130, the second lever 140 is rotated with reference to the rotating shaft 142 of the second lever 140, and the reel case One side of the second lever 140 that is locked by the locking portion 122 of 120 and prevents the reel case 120 from rotating is deviated from the locking portion 122 of the reel case 120. When one side of the second lever 140 deviates from the locking portion 122 of the reel case 120 in this way, the cable 20 is connected to the reel case 120 while the reel case 120 that has received elasticity against rotation by the rotating elastic body is rotated. Rolled up. That is, as shown in FIG. 3C, when the user rotates the plug 30 and the first lever 130 toward the center of the reel case 120 with the plug 30 inserted, one side of the second lever 140 is the reel. The reel case 120 rotates while deviating from the locking portion of the case 120 and the cable 20 is wound around the reel case 120. At this time, when the external force applied to the first lever 130 disappears by the user, the first lever 130 and the second lever 140 are returned to their original positions by the elastic portion 138 and the restoring elastic body 150 of the first lever 130. However, one side of the second lever 140 is locked to the locking portion 122 of the reel case 120, whereby the rotation of the reel case 120 is stopped.

  For this reason, since the reel case 120 is rotated by the rotating elastic body and the cable 20 is wound into the housing 10 only when the user applies an external force to the first lever 130 to rotate the first lever 130, Even when the cable 20 is completely pulled out, the user can adjust the length of the cable 20 to be pulled out as desired.

<Second Embodiment>
The headphone winding device 200 corresponding to the second embodiment of the present invention includes a housing 10, a cable 20, a base plate 210, a reel case 220, a rotating elastic body (not shown), a first A lever 230, a second lever 240, and a restoring elastic body 250 are provided. A headphone winding device 200 corresponding to the second embodiment of the present invention will be described below with reference to FIGS.

  Similar to the housing 10 of the first embodiment, the housing 10 has a housing space in which a large number of components can be housed. The housing space includes a base plate 210, a reel case 220, and a first lever 230. Then, the second lever 240 and the restoring elastic body 250 are accommodated. In the housing space of the housing 10, a transducer that converts an input electrical signal into sound and outputs it can be housed together.

  The cable 20 is formed with a plug 30 on one side that can be connected to the external device so that an electrical signal is input from the external device to the transducer accommodated in the housing 10. The electrical signal is passed to the transducer.

  At this time, it is preferable to use an L-shaped plug as the plug 30, and a locking projection 32 is provided in the vicinity of the grip portion of the plug 30.

  The base plate 210 is coupled to the housing 10 while being accommodated in the accommodating space of the housing 10, and provides a shaft for rotating the reel case 220.

  As in the first embodiment, the reel case 220 is configured to be coupled to the base plate 210 so as to be able to rotate 360 ° on the base plate 210, and one or more locking portions 222 are formed at the edge. The

  Preferably, the rotational elastic body is located between the reel case 220 and the base plate 210 and continuously provides elasticity to the reel case 220 for the rotation of the reel case 220. It is preferable to use a mainspring or the like.

  The first lever 230 is housed in the housing space of the housing 10, and an insertion portion 232 into which the plug 30 is inserted is formed on one side, and the plug 30 is formed at the inlet of the insertion portion 232. A locking groove 234 for receiving the locking protrusion 32 is recessed. An operation unit 236 for operating the second lever 240 is formed on the other side of the first lever 230.

  The operating portion 236 preferably has a semi-cylindrical shape when the first lever 230 is formed in a cylindrical shape, but the first lever 230 has a predetermined distance in the direction in which the plug 30 is inserted by the plug 30. After moving and rotating the second lever 240, the semi-cylindrical operation part 236 is rotated with the longitudinal axis of the first lever 230 as a reference by the rotation of the first lever 230, and the second lever Press to activate 240.

  The restoring elastic body 250 applies restoring force when the first lever 230 is moved by a predetermined distance in the direction in which the plug 30 is inserted by the plug 30, and restoring force with respect to the rotation of the first lever 230. Add

  The second lever 240 is prevented from rotating the reel case 220 when one side is locked to the locking portion 222 of the reel case 220. Then, the other side of the second lever 240 is positioned on the operating portion 236 side of the first lever 230 and is primarily rotated as the first lever 230 moves, and then the second lever 240 is rotated by the rotation of the first lever 230. The second rotation of the second lever 240 prevents the one side of the second lever 240 from being locked by the locking portion 222 of the reel case 220.

  Next, based on FIGS. 5 to 8, the operation of the headphone winding device 200 having the above-described configuration corresponding to the second embodiment of the present invention will be described.

  As shown in FIG. 5, the plug 30 is inserted into the insertion portion 232 of the first lever 230, but the locking protrusion 32 formed on the plug 30 is formed on the first lever 230 so as to correspond to it. The plug 30 is inserted so as to be fitted into the locking groove 234. As shown in FIG. 6, the first lever 230 is moved by a predetermined distance in the direction in which the plug 30 is inserted into the first lever 230 by an external force, but is preferably moved by about 1 to 2 mm. . At this time, the second lever 240 generates a primary rotation corresponding to the movement of the first lever 230. At this time, the rotation is preferably performed at about 3 to 5 degrees.

  Thereafter, as shown in FIG. 7, the plug 30 inserted in the first lever 230 is rotated by a predetermined angle about an axis that forms an angle of 0 ° to 90 ° with the longitudinal axis of the first lever 230. However, at this time, the rotation angle is preferably about 5 to 15 °. When the plug 30 is rotated in this way, the first lever 230 is rotated with the plug 30 due to the engagement between the locking protrusion 32 of the plug 30 and the locking groove 234 of the first lever 230. The operating portion 236 of the first lever 230 is rotated.

  At this time, since the operation part 236 of the first lever 230 has a semi-cylindrical shape, the second lever 240 is secondarily rotated by the rotation of the operation part 236. During the primary rotation of the second lever 240, the second lever 240 does not deviate from the engaging portion 222 of the reel case 220, so that the reel case 220 does not rotate, but the second lever 240 is rotated secondarily. Then, since the second lever 240 is deviated from the engaging portion 222 of the reel case 220, the reel case 220 is rotated by the rotating elastic body, and the cable 20 is wound around the reel case 220.

  On the other hand, the movement of the first lever 230 in the vertical direction and the rotation of the plug 30 are performed by an external force by the user. The winding device 200 for headphones according to the second embodiment is also used for the headphones according to the first embodiment. As in the case of the winding device 100, it is preferable that the above-described operation occurs only at the moment when an external force is applied by the user.

  A restoring elastic body 250 is attached to the first lever 230, and a restoring force acts on the operation of the first lever 230. That is, as shown in FIG. 4, the first lever 230 is fitted with a restoring elastic body 250 such as a spring on the other side, and the restoring elastic body 250 is fixed to a fixed end formed in the housing 10. For this reason, when the first lever 230 is moved in the longitudinal direction of the first lever 230, the restoring elastic body 250 is compressed to apply a restoring force to the movement to the first lever 230, and the first lever 230 rotates. When this is done, the restoring elastic body 250 is twisted by rotation and a torsion acts to apply a restoring force against the rotation of the first lever 230 to the first lever 230.

  Therefore, when the external force applied to the first lever 230 disappears, the first lever 230 returns to its original state as shown in FIG. 8, and the rotation of the reel case 220 stops. As a result, the cable 20 is not wound around the reel case 220 any more. That is, the moment when the user applies external force to the first lever 230 for movement and rotation, the reel case 220 is rotated by the rotating elastic body, and the cable 20 is wound around the reel case 220 to remove the external force. In addition, since the movement and rotation of the first lever 230 returns to the original state and the rotation of the reel case 220 stops and the cable 20 does not wind up around the reel case 220 any more, as in the first embodiment, the cable 20 It is possible to adjust the length of the cable 20 in a state where the cable is pulled out to the outside.

  As described above, the specific description of the present invention has been made by the embodiments based on the accompanying drawings. However, the above-described embodiments are only described by way of preferred examples of the present invention. The invention should not be understood as being limited to the above-described embodiments, and the scope of the invention should be understood as the claims and their equivalents.
