The present invention relates to a wireless headset, and more particularly, to a wireless headset which is convenient to carry and use and which can protect the earphone from foreign matter attachment or contact with other objects.

Recently, various wireless headsets connected to various electronic devices using short-range wireless communication have been developed. In particular, a Bluetooth headset capable of wirelessly transmitting and receiving voice data has been developed by applying Bluetooth technology.

A general Bluetooth headset (hereinafter referred to as a "wireless headset") includes a main body, a Bluetooth module embedded in the main body, earphones provided on one side of the main body, and a microphone provided on the other side of the main body. The earphone is configured to be inserted into the user's ear while protruding from the body, and simultaneously plays a role of supporting the wireless headset in a user's ear.

The wireless headset having such a configuration is wirelessly connected to various electronic devices, for example, a mobile phone, a PDA, a computer, etc. in a state of being fixed to the user's ear, so as to provide voice data transmitted from the electronic device to the wearer or to provide the voice data of the user Send to the device.

However, such a conventional wireless headset has a disadvantage in that it is inconvenient to carry or store since the earphone inserted in the ear of the user protrudes from the main body. In particular, there is a problem that earphones protruding from the main body are damaged due to interference or collision with other objects. In addition, the earphone protruding from the main body has a problem of being easily contaminated while being in contact with another adjacent object.

In view of these problems, a number of wireless headsets have recently been proposed, which are easy to carry and can protect earphones from adhesion of foreign matter or contact with other objects. As an example, there is a "wireless headset with earset" of Republic of Korea Utility Model Publication No. 393227.

This technique is a configuration in which an accommodating groove is formed in the center of the main body, and then the ear set can be accommodated in the accommodating groove. It is configured to protrude.

Such a wireless headset is stored in the main body when the earphone is not in use, thereby eliminating the inconvenience caused by the protrusion of the earset when carrying and storing. In addition, it prevents damage and breakage of the ear set due to the protrusion of the ear set, and also prevents contamination by foreign substances at the source.

However, the conventional wireless headset has a disadvantage that the installation space for the various parts embedded in the main body becomes narrow because the receiving groove for accommodating the ear set is formed in the center of the main body. There is a problem that it must grow.

In addition, in the conventional wireless headset, since the ear set is rotatably installed in the main body, even when the ear set is not used, there is a problem that the ear set is rotated to move away from the receiving groove and exposed to the outer surface of the main body. In particular, since the ear set is elastically pressurized in the direction away from the receiving groove by the restoring force of the torsion spring, there is a problem in that the ear set is easily detached from the receiving groove and protrudes to the outer surface of the main body even under a small impact.
