Abstract

PURPOSE:To prevent entanglement of a left and a right earphone cable when they are accommodated, by furnishing a fastener at the side of each earphone cable, left and right, and installing a chuck to open and close the fasteners. CONSTITUTION:A male fastener member 18 is furnished at the side of either of a left and a right cable 11, 13 of earphones 10, 12 for use at the left and right ears, while a female fastener member 19 is provided at the side of the other cable, and a chuck 14 is installed to open and close these fastener members 18, 19. The male 18 should have an approx. circular or rhombic form, while the female member is embodied in such a structure 19/22 as enwrapping the circular-form male member 18 or a male fastener member 21 in rhombic form.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereo earphone cable, and more particularly to a device capable of storing two cables without entanglement.

[0002]

2. Description of the Related Art Conventionally, earphones have been used for listening to audio in audio devices such as headphone devices and compact desk devices, and wireless devices. As shown in FIG. 3, two earphones 1 and 3 are used when listening to sounds with both left and right ears, but when the device is not used, the earphones are removed and stored in a bag, a pocket or the like. One end of the bundled wire 5 that bundles the two cables is connected to the plug 6, and the other ends of the bundled wire 5 are connected to the earphone cables 2 and 4 so that the earphones 1 and 3 are used for both ears. Since one of the earphone cables 2 and 4 has a short length, but the other has a long length (about 50 cm), the two earphone cables 2 and 4 are entangled with each other when they are stored, and the two earphone cables are used at the time of use. Cables were often difficult to separate and often difficult to separate.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and an object thereof is to prevent two earphone cables from being entangled when they are stored.

[0004]

In order to solve the above-mentioned problems, according to the present invention, in a cable of an earphone used for both ears, a male fastener is provided on the side portion of one of the left and right cables, and the cable of the other cable is provided. The present invention provides a stereo earphone cable characterized in that a female fastener is provided on a side portion and a chuck for opening and closing the male and female fasteners is provided.

[0005]

According to the above construction, when the earphone is stored,
Slide the chuck to fit the male fastener formed on the cable of the left earphone and the female fastener formed on the cable of the right earphone.

[0006]

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, 10 is a left earphone,
Converts electrical signals of sound into voice. 11 is the left cable,
A sound signal (left) from a device such as a headphone stereo is transmitted to the left earphone 10. Reference numeral 12 is a right earphone, which converts an electric signal of sound into a voice. A right cable 13 transmits a sound signal (right) from a device such as a headphone stereo to the right earphone 13. 14 is a chuck, left cable 1
The cable 1 and the right cable 13 are bound together and slid along them to fit or separate the cables 11 and 13. 15 is a state in which the left cable 11 and the right cable 13 are fitted together. Reference numeral 16 denotes a cable, which is a bundle of the left cable 11 and the right cable 13, the other end of which is connected to a plug or the like. 17 is a band, left and right cables 11, 1
3 is formed at the connecting portion of the cable 16 to prevent the cable 16 from being separated into two, and also serves as a stopper for the chuck 14. Reference numeral 18 denotes a male fastener, which is circular and is formed on the side portion of the left cable 11. A female fastener 19 is formed on the side portion of the left cable 13. Reference numeral 20 denotes an electric wire, which is arranged at the center of the left and right cables 11 and 13 and transmits a sound signal of a headphone stereo or the like to an earphone via a plug. In the above configuration, for example, when the use of the headphone stereo is stopped and the earphones are stored in the bag or the like, when the chuck 14 which is bound to the left and right cables 11 and 13 is slid toward the left and right earphones 10 and 12, a male fastener is formed. 18 and female fastener 19
When combined, both cables 11 and 13 become one cable. Next, when using a headphone stereo, the chuck 14 is taken out of the bag and slid in the direction of the band 17 and moved to a position a where it abuts on the band 17. At this time, the male fastener 18 is separated from the female fastener 19, and the left and right cables 11 and 13 become two cables, so that the left and right earphones 10 and 12 are attached to their ears. In another embodiment, as shown in FIG. 2, reference numeral 21 is a male fastener, and the protrusion of the fastener has a diamond shape, and the left cable 11
Is formed on the side part of. Reference numeral 22 denotes a female fastener, which is formed in a structure for tying the diamond fastener portion of the male fastener 21 and is formed on a side portion of the right cable 13. The fastener function can be similarly provided by using an elliptical shape instead of the diamond shape of the protrusion of the fastener.

[0007]

As described above, according to the present invention, the fastener portions are formed on the side portions of the cables of the left and right earphones, and the left and right cables are fitted into each other when they are stored to form one cable. It has the advantage that each user can adjust the two cables to the desired length with a fastener.
