Description

Anti-tangle of earphone cord {ANTI-TANGLE OF EARPHONE CORD}

The present invention relates to a tangle prevention device for an earphone cord. More specifically, a pair of fastening parts each having a protrusion and a groove are formed on the head of the earphone, and a main male led part and a main female led part are formed on the string adjacent to the connection terminal of the earphone. It relates to a tangle prevention device for an earphone cord that is connected by inserting a fastening part into the main part formed on both sides.

In general, earphones use the principle that when a plug is connected to various media devices, a weak electricity flows and a magnetic field is created around the enamel wire, which causes the aluminum foil attached to the enamel wire to vibrate, causing the surrounding air to vibrate and produce sound.

In particular, earphones are those that can be used by inserting them into the ear holes, and headphones that are worn on the head and cover the ears are called headphones.

These earphones are sold paired with audio media even as the portable audio media market transitions from cassette tapes to CDs and from CDs to MP3s.

In addition, buyers who purchase earphones consider sound pressure level, sound pressure sensitivity, impedance, etc. according to their preferred music style and taste.

Recently, earphone users have become more popular because they can use smartphones hands-free and do their own work without disturbing others, such as listening to music while leaving work, going to and from school, exercising or walking, or watching video lectures at home or in the library. The number is increasing further.

However, earphones have long cables, so in most cases, after using the earphones, you store them in your pocket or bag, and when you take them out to use them again, the cables are tangled.

In particular, there is a disadvantage of having to spend unnecessary time untangling tangled earphones. Also, if tangles are repeated continuously, there is a problem that the inner wire of the earphone cable may be short-circuited.

As a conventional technology to improve this problem, looking at the mobile phone earphone of Korea Utility Model Registration No. 20-0170150 (registered on November 24, 1999), a self-winding cord reel is built into the reel case and one side of the reel case is In forming a cord entrance to allow the cord connected to the earphones to pass in and out and insert a jack into the jack holder formed on the other side, the cord is separated into a long jack for earphones and a much shorter jack, and on one side of the cord reel there is an extension of the cord connected to the earphones. An equal number of point terminals are attached at a certain distance in the centrifugal direction and connected to the extension of the cord in pairs, and on the inside of the reel case facing the point terminals, a jack is arranged in a concentric circle with the circular terminals for each orbit of the point terminals as the starting point. A configuration is provided in which a printed board is attached, but each circular terminal and the jack's code extension are connected in pairs with conductors.

However, the conventional portable earphones described above have the advantage of preventing the earphone cable from becoming tangled, but the reel case has the disadvantage of being heavy due to the function of automatically winding the earphone cable. Also, if you listen to music with the left and right speakers plugged into your ears, the weight of the reel case can put a strain on your ears.
