The elastic support part 900 protrudes from the rear surface of the main body 100, and is spaced apart from a plurality of guide members 910 in which the inner slide groove 911 is opened to the rear, and the rear of the main body 100, and the slide groove A support plate 920 from which a plurality of slide protrusions 921 protrude from the front side so as to be inserted corresponding to the 911, and the guide member 910 are coupled to the outside, and both ends of the main body 100 and the support plate 910 are front and rear. It may further include an elastic member 930 for elastically supporting in the direction.

The guide member 910 may protrude to a certain length toward the rear of the main body 100 , and may be respectively disposed in the left and right and up and down directions of the main body 100 , but the number and position of the guide members 910 may be determined as needed. Various applications are possible. In addition, a stepped 911a may protrude from the inner peripheral surface of the entrance side of the slide groove 911 , and the stepped 911a may be continuously formed along the inner peripheral surface of the slide groove 911 .

The support plate 920 is a portion in which the rear surface is in contact with one side of the helmet 10 and is provided to be movable in the front-rear direction. A cushion part (rubber, sponge, etc., 160) for raising it may be coupled. That is, since the width of the support plate 920 facing the gripper 820 is variably adjusted, it can be applied to the helmet 10 of various thicknesses.

The slide protrusion 921 is inserted to correspond to the slide groove 911 and slides in the front and rear directions, and protrudes from the front surface of the support plate 920 by a predetermined length, and the front end is inserted to correspond to the slide groove 911 . . Here, a locking end 921a for preventing the slide protrusion 921 from being separated may protrude from the side of the slide protrusion 921 .

The locking end 921a may be positioned adjacent to the front end of the slide protrusion 921 , and may be continuously formed along the outer circumferential surface of the slide protrusion 921 . Such a locking end 921a is located in front of the step 911a, and when the slide protrusion 921 moves to the maximum moving distance in the rear, it is caught at the front end of the step 911a and the slide protrusion 921 is separated. to prevent

The elastic member 930 applies a compressive elastic force in the front-rear direction while individually coupled to the outside of the guide members 910 . Here, the elastic member 930 may use a coil spring for applying a compressive elastic force in the front and rear directions, and the front and rear ends of the elastic member 930 support the rear surface of the main body 100 and the front surface of the support plate 920 , respectively. And, the support plate 920 is located in a state elastically supported by the elastic member (930).

For example, when the headset of the present invention is coupled to the lower end of one side of the helmet 10 , the front of the gripper 820 elastically supports the inner circumferential surface of the helmet 10 in the direction of the body 100 , and the support plate 920 . One side of the helmet 10 is elastically supported in the direction of the gripper 820 by the compressive elastic force of the elastic member 930 . That is, since the outer surface and the inner surface of the helmet 10 are respectively elastically gripped in the direction in which the gripper 820 and the support plate 920 face each other, the coupling force can be further improved, and the fixing part 800 is attached to the helmet 10 . It is possible to separate the main body 100 by pulling it out downward, so that it is easy to combine and separate the headset.

On the other hand, the support plate 910 may be divided into a number based on the cut-off line 922 as in FIGS. 15 and 16 , and the guide member 910 and the elastic member 930 are individually separated in front of the divided support plate 910 . can be positioned as In this case, since the support plates 910 are independently movable, they can support one side of the helmet 10 at different positions, and the rear surfaces of the support plates 910 can be deformed into a shape corresponding to the side shape of the helmet 10 . Therefore, the area in contact with the side surface of the helmet 10 can be increased.

For example, when the headset of the present invention is coupled to the lower end of one side of the helmet 10, the front of the gripper 820 elastically supports the inner circumferential surface of the helmet 10 in the direction of the support plate 920, and the support plate 920. One side of the helmet 10 is elastically supported in the direction of the gripper 820 by the compressive elastic force of the elastic member 930 . At this time, since the support plates 920 are in close contact with a large area while being deformed into a shape corresponding to the side surface of the helmet 10, the coupling force can be further improved.

That is, when one side of the helmet 10 is formed in a curved surface, the contact area between the rear surface of the support plate 920 and the helmet 10 may be formed to be narrow. When the support plate 920 is separately formed, the helmet 10 It can be used in various types of helmet 10 because it can be closely adhered to the shape corresponding to the shape of A strong bonding force can be maintained even without member bonding.

As a result, according to the present invention, the gripper 820 can be coupled to the lower end of one side of the helmet 10, so that the mounting and detaching process of the headset is easy, and the body 100 and the coupling member 810 are firmly attached. Since the position of the main body 100 is not changed or separated due to external force (shock, vibration, etc.) while driving the motorcycle, there is no concern that the position of the main body 100 is changed or separated, and the distance between the coupler 810 and the gripper 820 is adjusted. Since this is possible, it can be used for various types of helmets 10 in general.

Although specific embodiments of the Bluetooth headset capable of multiple communication according to the present invention have been described so far, it is apparent that various implementation modifications are possible within the limits that do not depart from the scope of the present invention.
