Description

Wireless Hands Free Earphones {Wireless Hand Free Earphone}

The present invention relates to a wireless handsfree earphone, and more particularly, to a wireless handsfree earphone which can freely select and use both left and right ears of a person.

In general, in the case of a wireless handsfree earphone, a battery, a receiver, a controller, and the like must be mounted in the wireless handsfree earphone itself, so that the weight is heavier and bulkier than the conventional wired earphone. In particular, because of the heavier weight than conventional wired earphones, wireless hands-free earphones cannot be used simply by inserting them into the ear, and thus, the earring part that can be used on the ear is prepared, and this earring part is mainly used in the structure. However, in such a structure, the ear insertion part which is inserted into the ear and transmits the sound must be prepared in advance so as to face the left or right side of the earring part according to the ear to be used. Therefore, there is a problem that producers have a burden of producing and distributing both models on the left or right side, and from the consumer's point of view, they must purchase both models in order to freely select both left and right ears. If you buy a problem that had to be used to install only one ear.

In consideration of these problems, the speaker is installed in the main body fixing part and two through holes having a distance between 120 ° and 170 ° are formed in the main body fixing part, but the sound wave transmission passage and the main body of the ear insertion part are located along the left and right ears. The technology has been disclosed to allow the left and right both sides to communicate with any one of these through-holes formed in the fixed part, but can be used only in the position where the through-holes formed in the body fixing part and the sound wave transmission passages of the ear inserts coincide. The ear insertion part should be rotated so that the sound wave transmission path is placed only at the position of the through hole formed at the time. Therefore, the earphone has been set at various angles so that it cannot be used on the left and right ears.

On the other hand, there are many cases where a microphone is attached to a wireless handsfree earphone, which is generally arranged in consideration of a direction suitable for one of both ears of a person wearing the wireless handsfree earphone, or both. Since it is disposed in an approximately intermediate position without any obstacles, there is a problem in that the sound transmission of the micro is inevitably lost due to failure to obtain an optimized angle to direct the sound transmission hole toward the sound direction.

Accordingly, an object of the present invention is to provide a wireless hands-free earphone that can be used in both ears as well as can be set at various angles when used in each ear, in order to solve such problems in the related art.

Another object of the present invention is to provide a wireless hands-free earphone which can prevent the wire connected to the speaker from being twisted by rotating the ear insert.

On the other hand, another object of the present invention is to provide a wireless hands-free earphone that can properly rotate the microphone to reduce the loss of sound transmitted to the microphone even when used in both ears.
