Abstract
A mask according to an embodiment comprises: a body having a shape corresponding to a user's face; a first recess disposed on one surface of the body, opposite to the user's face; and a piezoelectric part disposed in the first recess, wherein the first recess has a shape recessed outward from the one surface of the body and is disposed in a region corresponding to at least one of the user's brow region and eye rim regions, and the piezoelectric unit protrudes beyond the one surface toward the user.
Claims16
A mask comprising:
- a body having a shape corresponding to a user's face;
- a first recess disposed on one surface of the body;
- and
- a piezoelectric part disposed in the first recess,
- wherein the first recess has a concave shape from one surface of the body in an outward direction and is disposed in a region corresponding to at least one of the user's brow region and eye rim regions,
- wherein the piezoelectric part protrudes further toward the user than one surface of the body,
- wherein the body includes:
- a first support member;
- a second support member disposed below the first support member;
- and
- a third support member disposed between the first and second support members,
- wherein the third support member includes a material different from that of the first and second support members,
- wherein the piezoelectric part has a shape corresponding to the first recess,
- wherein the first recess is formed on the first support member and exposes an upper surface of the third support member,
- wherein the mask further comprises a second recess disposed in the first recess and formed on the third support member, and
- wherein the second recess exposes an upper surface of the second support member.
