Description

  The present invention relates to a headphone cable entanglement prevention structure for preventing cable entanglement in headphones.

  In recent years, portable audio devices (for example, cassette players, MD players, CD players, etc.) have become widespread. Such portable audio devices are headphones connected to the main body (various names are used by sound manufacturers, etc., but in this specification, stereophones to be applied to both ears and earphones and earphones of the type to be inserted into the ears) In general, a method of listening to sounds such as music via It consists of two cables that connect from the plug terminal to the headphone body that touches both ears. It is integrated on the plug terminal side, and is branched from the middle to connect to the headphone body for the right and left ears. It has become. These portable audio devices and headphones connected thereto are generally used when walking or getting on a train or the like. At that time, the portable audio device is housed in a bag or pocket, and it is normal to listen to the sound through headphones connected to the audio device. And when you stop using, remove the headphone body from both ears and store it in your bag or pocket. When using the audio equipment again, take out the headphones from the bag or pocket.

  However, when storing conventional headphones in a bag or pocket, the main cable on the plug terminal side and the branch cable on the ear side that is divided into left and right are entangled and tied, so after unwinding There was a drawback that had to be used.

A conventional headphone cable has the following drawbacks.
When storing and carrying the headphones, the headphones cables get entangled in the bag or pocket. For this reason, after taking out the headphones from the bag or pocket, it is necessary to use them after untangling them. The work of releasing the entanglement is complicated and meaningless, and forcibly pulling the cable may cause damage to the cable or the headphone body.

  The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a structure for preventing entanglement of headphones cables. In addition, the conventional entanglement prevention structure for headphones has the disadvantages that the prevention of entanglement is not reliable, it takes time to fix, and the mechanism is complicated, so it prevents the entanglement more reliably and requires less work time to fix, more The purpose is to provide a structure that is simple in structure.

As a result of examining the entanglement of the headphone cable described above, the entanglement of the headphone cable is made up of two L-shaped headphone bodies (3) and plug terminals (6) provided at the end of the flexible cable. It is possible to move freely in each, and because the cable is long, it can move freely and entangle with each other. We thought that entanglement of the cable could be prevented by suppressing this free movement. Therefore, the following entanglement prevention structure is proposed.
(A) The main cable (5) from the plug terminal (6) in contact with the audio equipment and the branch cable to the ear (4) A sleeve (1) for making a U-turn of the cable is provided at two branch points.
(B) Following the sleeve (1), provide two or more sliders (2) through which the cable (5) and the two branch cables (4) pass through different holes. When storing and carrying the headphones, slide the slider near the headphone body (3) and the middle point (7) to align the three cables and prevent them from being entangled.
(C) The shape and color should be devised so that two or more sleeves (1) and sliders (2) can be seen together without using the headphones.
The present invention is a structure for preventing entanglement of a cable of a headphone as described above.

According to the headphones having the cable entanglement prevention structure of the present invention, the following effects can be obtained.
(B) When carrying the headphones in a bag or pocket, just slide the slider near the headphone main body and the middle point, etc. to connect the three cables (one cable on the plug terminal side, branch cable on the headphone body side) 2) can be easily aligned and bundled, and free movement of the headphone body can also be restricted, so that the cable and headphone body can move freely even when subjected to vibration in a bag or pocket. In addition, cable entanglement can be prevented more reliably. Therefore, it is possible to save the trouble of entanglement and to reduce the damage of cables and headphones.
(B) When using headphones, the slider is slid to the sleeve, so the sleeve and the slider are integrated and do not interfere with the use of the headphones.
(C) Fixing cables and headphones is easy because you only need to slide the slider, and you can search and collect them by hand. Cables can be bundled together.
(D) By devising the material and color of the sleeve and slider, it can be integrated with the cable so that it does not stand out, and by devising the color and shape, the design can be increased to suit the fashion.
(E) Since the structure is simpler than the methods of Patent Documents 5 to 8 and the New Application Document 2, it is easy to manufacture and can be manufactured at a low unit price.
