Abstract: An automatic winding module of a wire for Bluetooth headset with an improved wear resistance function of a rotation axis, which firmly maintains a rotation axis without twist of the rotation axis even in case of using it for a long time, thereby preventing breakaway between a terminal and a PCB pattern, to prevent a short circuit from occurring.

Abstract: A Bluetooth neck band headset comprises a tube frame maintaining a shape of the neck band, base frames provided on both sides of the tube frame, a Bluetooth module provided in the base frame and performing two-way data communication by interworking with the terminal of the user, a vibration speaker provided on one surface of each base frame, an earphone coupled to one side of each base frame and outputting sound, a control module controlling any one or more of the vibration speaker, the earphone and the Bluetooth module, a power button provided on one surface of the base frame, and a volume button controlling the intensity of sound output of any one or more of the earphone and the vibration speaker.

Abstract: An automatic rewinding apparatus with an abrasion-resistant rotation axis includes: a main base lower housing including a cylindrical fixing axis at a center; a PCB substrate penetrated by the fixing axis and combined with the main base lower housing; a contact terminal coupling plate; a middle base coil housing including: a sub-base lower housing, a cylindrical winding bobbin, a sub-base upper housing, and an abrasion-resistance improving insert disposed on internal circumferential surfaces of punctured centers of the sub-base lower housing, the winding bobbin and the sub-base upper housing; a rolling elastic member with elasticity; grease cover plates on both sides of the rolling elastic member; a cap for covering the opening of the sub-base upper housing and combination with the sub-base upper housing; a stopper ball; and a main base upper housing combined with the main base lower housing and covering a second side where the track of the cap.
