Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is used for earphones used in mobile radios and cassette tape recorders, mobile phones for automobiles, cordless phones, transceivers, etc., and hands-free calling (because both hands are free, talking while doing other tasks such as driving) With regard to the small earphone cord winder (with microphone), the two cords on the receiver (ear) side and the plug (phone) side are independent, and the cord can be wound and pulled out freely. Since the cord length can be adjusted freely, you have more freedom to place your mobile phone, and it is possible to remove the earphone cord from an uncomfortable posture and extra slack, making it lightweight, compact, and thin. It is related to a compact earphone cord winder.

[0002]

[Prior art]

 As a conventional example, a hands-free call using an earphone cord (with a microphone) of an automobile mobile phone will be described. The location of automobile mobile phones is generally not fixed between seats, seats, dashboards, etc. Conventionally, as shown in FIG. 2, only the receiver (ear) 5'side can be wound, and the cord on the plug (telephone) 2'side has a fixed length. For this reason, the winder has to be placed near the main body of the radio, telephone, etc., and the location of the main body is limited, which not only lacks flexibility, but also makes it impossible to take out the receiver. You may be forced to interfere with safe driving. On the other hand, when the cord length on the plug (telephone) side is too long, extra slack is generated, and there is the drawback that it does not look sloppy and smart.

[0003]

[Means for Solving the Problems]

In order to solve these drawbacks, the present invention has been earnestly studied, and as a result, it is possible to obtain a degree of freedom in the place where the mobile phone is placed, and it is possible to eliminate an unnecessary posture and extra slack for taking out the earphone cord. The purpose of the present invention is to provide a small earphone cord winder 1 that is lighter, smaller, and thinner, and its gist is to wind the receiver 5 side cord and the plug 2 side cord, or The first take-up reel 9 and the second take-up reel 10 for pulling out are individually provided in upper and lower two stages, and the first stopper part 12 and the second stopper part 13 are respectively provided corresponding to the take-up reel. The upper and lower electrode patterns 7 are connected to each other through the through-hole 8 of the board, and the double-sided through-hole board 6 is arranged between the both cords, and the upper and lower take-up reel cords are respectively connected and wound up. Lumpur side electrode contact 11, a small earphone cord winder, characterized in that electrically connected to slide on the upper and lower electrode patterns 7.

【Example】

Hereinafter, an embodiment of the small earphone cord winder 1 of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 (a) is a perspective view showing an embodiment of the use of the small earphone cord winder 1 of the present invention. As is clear from the figure, the small earphone cord winder 1 of the present invention has a small microphone 4 and a receiver 5 side for listening to the ear 2 and a plug 2 side for inserting into a jack (not shown) of the mobile phone 3. The cords of each book are made independent, and the cords can be wound and pulled out freely, and the length of both cords can be freely adjusted. FIG. 1B is a schematic perspective view of the small earphone cord winder 1 of the present invention. Conventionally, the plug 2 side was fixed, but both the cord on the plug 2 side and the receiver 5 side are wound. Allows withdrawals. FIG. 1C is a cross-sectional view of the earphone cord winder 1 of the present invention. The receiver 5 side cord and the plug 2 side cord are independently wound or pulled out in two stages. The first take-up reel 9 and the second take-up reel 10 are provided on the above, and the double-sided through-hole substrate 6 is arranged between them. The double-sided through hole substrate 6 has electrode patterns 7 on both sides thereof, and the electrode patterns 7 are connected by through holes 8 and are connected to the cords of the upper and lower take-up reels, respectively. Further, the double-sided through-hole substrate 6 and the first take-up reel 9 and the second take-up reel 10 are electrically connected by the take-up reel side electrode contactor 11 sliding. In this way, since the double-sided through-hole substrate is used, it is possible to make it compact. Further, a force is always applied to the first and second take-up reels 9 and 10 in the direction in which the cord is wound, and the first stopper portion 12 and the second stopper portion 13 are respectively provided so that the cord can be maintained at an appropriate length. To provide. As is apparent from FIG. 1C, if the first stopper portion 12 and the second stopper portion 13 are pushed in the direction of the arrow, the engagement is released by the first and second springs 14 and 15, and the length can be freely adjusted. Can be changed to.

With the above-mentioned structure, when the small earphone cord winder 1 of the present invention is used in a portable radio, a cassette tape recorder, etc., the portable radio or tape recorder is put in a bag and the present invention is used. You can put the small earphone cord winder on the chest in a pocket such as the chest and adjust the receiver (ear) side cord and the plug (main body) side cord to an appropriate length without slack. Therefore, there is flexibility in the location of the sound source body and the chords are well stored, making it easy to use. Next, when making a hands-free call using the earphone cord (with microphone) of the mobile phone of the car, the small earphone cord winder of the present invention is fixedly installed near the driver, and the receiver (ear) cord Adjusting both the cords on the plug and telephone (phone) side to an appropriate length without slack eliminates the situation of having to drive in an unreasonable posture.

[0006]

[Effect of device]

As described above, according to the small earphone cord winder 1 of the present invention, when making a hands-free call, by placing the winder in the vicinity of the driver, the cord can be taken up and pulled out freely. Since the length can be adjusted freely, you can get the freedom to place your mobile phone. You can eliminate the unreasonable posture to take out the earphone cord, which contributes to safe driving. Both the cord on the receiver 5 side and the cord on the plug 2 side can be made slack, and it looks smart. It can be made lighter, smaller, and thinner. Because of the excellent effect, its industrial value is very large.
