The earphone includes various data through Bluetooth communication with the mobile terminal, Structure to send and receive signals In addition, since the earphone main body and each unit earphone are connected to each other by a wired connection with the mobile terminal, sound output can be performed while they are communicating with each other via Bluetooth, and the earphone main body and each unit earphone are set to be always kept in a paired state Therefore, it is possible to solve the inconvenience of the user performing a manual operation for connecting the mobile terminal and the multi-functional earphone through the Bluetooth communication,

Patent Document 2 discloses a microphone device having a body of a predetermined shape, a speaker device installed in the above place, a microphone device installed on the body so as to be separated from the speaker device by a predetermined distance, And a USB connector for selectively extending / inflating the ear hook and an USB connector for electrically connecting to the USB port of the PC and transmitting / receiving data to / from the terminal, In addition to the call, the built-in USB contactor is used as a wireless adapter for data transmission and reception by directly connecting with a PC. Therefore, it is advantageous in that it is not necessary to use a separate data cable or adapter,

Patent Document 3 discloses a Bluetooth built-in wireless earphone including a control body having a printed circuit board including a microphone connected to one earphone line of the earphone head and an adjustment button, and a Bluetooth module installed at the center of both earphone lines, And the earphone line is inserted into the fitting portion of the neckband which is formed by being closed and the other side is closed. The neckband and the Bluetooth built-in wireless earphone are mutually detachable by inserting the Bluetooth module into a housing formed at the center of the neckband And the housing of the neckband can be used as a necklace by making it into an ornamental shape. When the Bluetooth built-in wireless earphone is not used, the housing of the neckband is seen as an ornamental shape, thereby enhancing the appearance as a necklace, Germanium inside (usually germanium gemstones wind In the case of using a wireless built-in type wireless earphone, the earphone of the Bluetooth built-in wireless earphone can be used. In addition, The present invention provides a universal earphone that can be used both as a necklace and as a wireless earphone with a built-in Bluetooth by allowing the earphone and a Bluetooth module to be inserted into a fitting portion and a housing of the neckband, It is possible to eliminate the inconvenience due to the earphone string when worn.

However, in the above Patent Documents 1 to 3, it is impossible to adjust the size according to the neckline of the user. Particularly, in Patent Document 3, when a thick neck is used, The user feels uncomfortable with the neck, and when the neck is thin, the wearer feels uncomfortable due to a low seating feeling, and when an active schedule such as exercise is extinguished, And a Bluetooth headset corresponding to the Bluetooth headset is lost.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figures 1 and 2,

The present invention relates to a neckband-type Bluetooth headset that communicates data with a user terminal through a Bluetooth module,

A wire frame 100 that is seated in the rear of the user and has an insertion portion formed at both ends thereof,

And a flow guide groove (213) formed inside the wire frame (100) so that the inserting portion of the wire frame (100) is engaged with both ends of the wire frame (100) And a pair of bodies 200 which are seated in the vicinity of the left and right collarbone when worn.

In the wire frame 100, a connection frame 115 for connecting the respective insertion portions is formed between a pair of insertion portions formed at both ends.

The connection frame 115 includes a shape memory alloy 130 for elastically restoring the shape of the wire frame 100 and a wire 140 electrically connecting the pair of the bodies 200, And a tube 150 for protecting the connection frame 115 from an external impact is coupled to the outer peripheral surface.

The connection frame 115 includes at least one shearing engagement groove 114 to which the C-ring 124 is fastened at both sides, and the C-ring 124 is connected to the connection frame 115 After the tube 150 is coupled, the tube 150 is fastened to the connection frame 115 by being fastened at a position where the shearing engagement groove 114 is formed.

The insertion portion includes at least one O-ring coupling groove 113 to which the O-ring is coupled.

Referring to Figure 2,

At this time, an O-ring 123 may be fastened to the O-ring fastening groove 113.

The body 200 includes a top case 210a and a bottom case 210b which are coupled to each other.

3 to 4,

The wire frame 100 includes a hook portion 111 formed at an end portion of the insertion portion and engaged with the hooking step 211 and a hook portion 111 formed at the other side of the insertion portion to be engaged with the hooking protrusion 212 And a groove (112).

The hook portion 111 is configured to include a cut portion formed by cutting the center in the longitudinal direction and the end of the hook portion 111 is elastically bent toward the cut portion with the cut portion as a center, So that the hook portion 111 is elastically engaged with and separated from the hooking hook 211.

The body 200 includes a hooking protrusion 211 formed at one side of the flow guide groove 213 for hooking the hook portion 111 therebetween, And a latching protrusion 212 for latching the latching groove 112.

Therefore, in the body 200, the insertion portion of the wire frame 100 is moved in the longitudinal direction along the flow guide groove 213, and the O-ring 123 is moved in the flow guide groove The length of the Bluetooth headset of the present invention can be adjusted by adjusting the length of insertion and extraction of the end portion of the wire frame 100 from the body 200 by providing a friction force between the insertion portion and the insertion portion.

The insertion portion of the wire frame 100 may be inserted or withdrawn in the longitudinal direction along the flow guide groove 213 to the other end or the other end of the body 200, The length of the end portion of the wire frame 100 inserted and drawn out from the body 200 can be maximized or reduced by engaging the hooking step 211 with the engagement groove 112 or by engaging the engagement recess 112 with the engagement protrusion 212. [ So that the length of the Bluetooth headset of the present invention can be adjusted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is not.
