Referring to FIG. 8, two wireless headsets 100 are coupled to each other to form a stereo wireless headset 100.

In detail, the stereo type is a method of dividing each sound from a plurality of speakers by outputting a plurality of sound output directions. For example, two speakers in the stereo type have two output directions, and one speaker outputs a left sound and the other speaker outputs a right sound.

On the other hand, the mono type is a method in which the directionality of the sound output direction is single, and the left and right cannot be distinguished by the output sound. For example, two speakers of the mono type output only the same sound. The mono type in this embodiment can be optimized for reproduction of a voice signal for communication.

In the wireless headset of the present invention, a pair of wireless headsets for substantially outputting the sound signal is connected to the connection member, so that a perfect stereo reproduction is possible from the speakers of both wireless headsets.

In detail, the wireless headset of the present invention includes a stereo support connecting member 170 for interconnecting a pair of headset units. Accordingly, a user who wants to reproduce a sound signal in a stereo environment may output a music signal and listen to the wireless headset 100 having a stereo support connection member 170 connected to a pair of headset units. At this time, it is obvious that at least one side of the pair of headset units is equipped with a Bluetooth module to be configured to communicate with a parent such as a mobile phone or an MP3.

Meanwhile, referring to FIG. 9, the stereo support connecting member 180 may be implemented to be detachable from each headset unit. That is, one side of the headset unit may be provided with a connection member 180 for stereo support having a connection portion 181 formed therein, and a coupling unit (not shown) to which the connection portion 181 may be coupled may be formed in the other headset unit. . Accordingly, the stereo mode may be set when the connector 181 is coupled to the coupler, and the mono mode may be set when the connector 181 and the coupler are separated.

In this case, one side of the pair of headset units may be formed to serve as a main unit. In other words, one side of the pair of headset units, which serve as a main unit, is equipped with a Bluetooth module to perform communication with the mother, and at the same time, a microphone 160 and a coupler are provided. The role can be configured to be performed independently. Thus, when the main unit is used independently, the wireless headset is operated in mono type.

In addition, a connection member 180 of a flexible material having a connection portion 181 formed at one end is coupled to the headset unit on the other side serving as a sub unit. When the connection unit 181 of the sub unit is coupled to the coupling unit of the main unit, the wireless headset may be configured to operate in a stereo type.

Meanwhile, although not shown in the drawing, the stereo support connecting member 180 may be formed to be detachable to both headset units. That is, connecting portions 181 are formed at both ends of the stereo support connecting member 180, and a coupling hole is formed in each wireless headset so that the stereo mode is set when the connecting portion 181 is coupled to the headset unit at both sides. It would also be possible to implement. In this case, each headset unit may be used as a mono type wireless headset independently, and may be configured to be used as a stereo type wireless headset when both headset units are connected by the connection member 180.

Here, since the wireless headset is automatically switched to the mono type or the stereo type according to whether the connection member is connected, a detailed description thereof will be omitted here.

Meanwhile, referring to FIGS. 10 and 11, a neck band 190 may be further coupled to the stereo support connecting members 170 and 180.

In detail, in the conventional stereo headset, a neckband is used to stably fix the position in the wearing state of the headset, or a method in which both headset units are connected only by wires for ease of portability.

However, the conventional neckband type stereo headset as described above has a disadvantage in that it is not easy to carry and store due to the neckband. In addition, the wire-type stereo headset has a problem that the wearing position of the headset is not stably supported, and moreover, the wire is often entangled.

In order to solve the above problems, the wireless headset according to the present invention provides a detachable neckband 190 to the connection member 170,180. In other words, the wire receiving groove 191 is formed on one side of the neck band 190, and the stereo support connecting members 170 and 180 are detached from the wire receiving groove 191, the user's If necessary, it is possible to switch to a neckband method or a wire method.

According to the above configuration, when using in the interior of the office, such as using the neck band 190 attached to the wearing position of the headset to be stably supported, when moving the wireless band by detaching and carrying the neck band 190 There is an advantage that it is easy to carry and store.
