Abstract

A headset capable of wireless charging is provided. The headset capable of wireless charging according to one embodiment of the present invention comprises: a pair of body units including a housing equipped with a speaker and a cushion unit; a connecting unit configured to connect the pair of body units; a battery module embedded in at least one of the body units and connecting unit to provide driving power; and a wireless power receiving antenna configured to receive wireless power transmitted from the outside to supply power for charging the battery module.

First claim

1 . A headset capable of wireless charging, comprising:
a pair of body units each including a housing equipped with a speaker and a cushion unit; a connecting unit configured to connect the pair of body units; a battery module embedded in at least one of the body units and the connecting unit to provide driving power; and a wireless power receiving antenna configured to receive wireless power transmitted from the outside to supply power for charging the battery module.

2 . The headset of claim 1 , comprising a shielding sheet disposed on one surface of the wireless power receiving antenna so that a magnetic field generated from the wireless power receiving antenna is shielded to be collected in a predetermined direction.

3 . The headset of claim 1 , wherein:
the housing includes a winding portion formed to protrude to the outside; and the wireless power receiving antenna is wound along a circumferential surface of the winding portion.

4 . The headset of claim 3 , wherein the winding portion is formed at a position that does not overlap a metal portion of the speaker.

5 . The headset of claim 1 , wherein the wireless power receiving antenna is wound along an inner surface of the housing.

6 . The headset of claim 5 , wherein the wireless power receiving antenna is embedded in the housing and disposed behind the speaker.

7 . The headset of claim 1 , wherein the wireless power receiving antenna is embedded in the connecting unit.

8 . The headset of claim 1 , wherein the wireless power receiving antenna is embedded in each of the body unit and the connecting unit.

9 . The headset of claim 1 , wherein the battery module embedded in the connecting unit is a flexible battery.

10 . The headset of claim 9 , wherein:
the flexible battery includes an exterior material and an electrode assembly; the exterior material and the electrode assembly include a pattern for contraction and relaxation in a longitudinal direction; and the pattern formed in the exterior material and the pattern formed in the electrode assembly are formed to coincide with each other.

11 . A headset charging system using wireless power transfer, comprising:
the headset capable of wireless charging disclosed in claim 1 ; and a charging device including a wireless power transmitting antenna configured to provide wireless power to the headset to charge the battery module when the headset is held.

12 . The headset charging system of claim 11 , wherein the charging device includes a holding member on which the headset is held, and a wireless power transmitting antenna embedded in the holding member to be located at a position corresponding to the wireless power receiving antenna.

13 . The headset charging system of claim 12 , comprising a shielding sheet disposed on one surface of the wireless power transmitting antenna so that a magnetic field generated from the wireless power transmitting antenna is shielded to be collected in a predetermined direction.

14 . The headset charging system of claim 12 , wherein:
the holding member includes a base part and an accommodation part configured to protrude in both directions from the base part and having one end portion inserted into and disposed in a center portion of the cushion unit when the headset is held; and the wireless power transmitting antenna is embedded in an end portion of the accommodation part.

15 . The headset charging system of claim 12 , wherein:
the holding member includes a base part, and a protruding part configured to protrude in both directions from the base part and in which a seating groove, into which the body unit is inserted when the headset is held, is formed; and the wireless power transmitting antenna is embedded in the protruding part.

16 . The headset charging system of claim 12 , wherein:
the holding member includes a supporting part configured to support the middle portion of a length of the connecting unit; and the wireless power transmitting antenna is embedded in the supporting part.
