The present invention relates to a necklace-type wireless headset, more specifically, the "V" shaped earphones are inserted into the ear and there is no problem during use, but when the earphone is temporarily removed from the ear, it is difficult to store or carry it separately. The present invention relates to a necklace-type wireless headset that can be carried by hanging on a neck like a ring-shaped necklace by configuring both earphones connected by wires to be detachably attached by a coupling means.

In general, earphone is an abbreviation of earphone receiver (earphone receiver) is an electronic device that allows a user to listen to sound through a speaker by connecting to a sound device such as a wireless telephone or a mobile phone, a car phone, a cassette for recording and playback, a CD player, a small radio. The crystal receiver of the earphone receiver is a structure that operates the diaphragm using the piezoelectric effect of the crystal element, and the magnetic receiver has a structure that operates the diaphragm by flowing a voice current through the coil. In addition to the type that is directly plugged in the ear, there is also a type that is worn over the head, which is called a headphone (headphone) to distinguish it from an earphone.

However, although there are differences in the sizes of the different diaphragms or diaphragms and magnets, when all the currents flow through the electromagnets, the pushing force between the permanent magnets and the electromagnets changes depending on the strength and phase of the current, and a thin film is installed there. When the film is shaken, the sound is audible.

As described above, the operation principle of the earphone and the headphone is almost the same. But the headphones are worn over the head, and the earphones are inserted directly into the ears, and there are obvious differences in how they are worn. More subdivided, even though it is worn on the head, the set of the handset and the microphone is called a headset to distinguish it from the headphones. Headphones or headsets have both ears and one ear, and both ears have a stereo type and a mono type.

On the other hand, in order to fundamentally reduce the occurrence of traffic accidents caused by using a mobile phone while driving, it is strictly forbidden for the driver to talk to another person on the mobile phone while driving. Therefore, among the many new products available today to meet these regulations, the most common is a hands-free kit. The handsfree kit puts the mobile phone on the handsfree kit before the driver drives, and the speaker of the kit or the speaker system of the car broadcasts a call message arriving on the phone. This allows the driver to communicate with others without holding the phone by hand. Since hands-free kits are associated with the car's built-in speakers, this can result in too much noise or ringing when the driver speaks with others, so that arrival messages cannot be clearly received and privacy may be violated if other passengers are present. Can be. To address this drawback derived from hands-free kits, over-ear and headset wireless earphones are available on the market and plugged into the driver's ear or hooked to the wheel while the driver is talking to someone else. The call is not leaked, and there are no problems causing too much ringing.

As described above, in general, the earphone device has a wired earphone and a wireless earphone, wired earphone is connected to the earphone jack of the terminal, such as a cassette or CD player, receives the electrical signal transmitted from the terminal to the wire to convert the voice signal and output The wireless earphone further includes a wireless signal receiver for wirelessly receiving a signal transmitted from a wireless terminal such as a mobile phone, a PDA or a notebook computer to wirelessly receive a voice signal or a control signal.

In particular, in recent years, as communication between individuals through portable terminals has been expanded, various information communication services such as wireless calls, additional services, and SMS have been provided to the general public, and the communication method using a Bluetooth module is applied to earphones or other wireless terminals. Accordingly, the user may call with the other party through the earphone at a point away from some distance without directly holding the portable terminal.

Such a Bluetooth-embedded wireless earphone generally includes all components such as a Bluetooth chip, a battery, a speaker, a microphone, a reception button, and a mounting earring in one case. After forming a space part by a predetermined distance, the mounting earrings are configured to be worn over the auricle. In the case of the mono type, only one ear can be used, but in the case of the stereo type or the mono type, the pair of earphones are connected by a wire. Typically, one earphone has a speaker and an antenna, and the other earphone has a speaker and a battery.

By the way, the wire is not a problem because it is plugged into the ear or hanging on the wheel during use, but if you stop using it for a while, there is no place to keep it in the pocket and other places. As such, when the earphone is stored, the wires are twisted with each other or entangled with other items, which is very inconvenient. In particular, taking out the earphones stored in a crowded subway or bus and releasing the tangled lines can be cumbersome.
