Headset having variable band structure

A headset comprising:

• an ear unit configured to accommodate a speaker therein;
• a headband;
• a first connection member disposed inside the ear unit;
• and
• a second connection member coupled to the headband,
• wherein the second connection member comprises:
• a second support member connected to the first connection member such that the headband is pivotable;
• and
• an inclined surface provided to surround the second support member and disposed to form an inclined angle with a surface of the first connection member facing the inclined surface,
• wherein an uppermost portion of an incline of the inclined surface is disposed at a front portion of the headset,
• wherein the front portion of the headset when worn on an ear of the user corresponds to a front of the user's body,
• wherein the second connection member comprises a protrusion disposed on the inclined surface and disposed to rotate along the surface of the first connection member as the headband pivots, and
• wherein a distance between the inclined surface and the surface of the first connection member is configured to change at the front portion of the headset as the protrusion rotates along the surface of the first connection member.

A headset comprising:

• a headband;
• ear units at respective ends of the headband, each ear unit accommodating a speaker therein and comprising a first connection member;
• and
• second connection members coupled to the respective ends of the headband at the ear units,
• wherein:
• the respective first connection member comprises:
• a first support member connected to a corresponding one of the second connection members to form a connection about which the headband is pivotable;
• and
• an inclined surface provided about the first support member to form an inclined angle with a surface of the corresponding one of the second connection members facing the inclined surface,
• an uppermost portion of an incline of the inclined surface is disposed at a front portion of the headset,
• the corresponding one of the second connection members comprises a protrusion disposed on the surface facing the inclined surface for rotation along the inclined surface as the headband pivots, and
• wherein the front portion of the headset when worn on an ear of the user corresponds to a front of the user's body,
• wherein a distance between the inclined surface and the surface of the corresponding one of the second connection members is configured to change at the front portion of the headset as the protrusion rotates along the inclined surface.
