Abstract

An electronic device according to an aspect of the present invention comprises a case formed of an ultra-light fabric material; a frame coupled to the case and supporting the case; and a face pad coupled to the frame, wherein ultra-light fabric material comprises an ultra-light material comprising a thermoplastic resin and a core material dispersed in thermoplastic resin; and a fabric thermo-compressed on at least one side of the ultra-light material by thermoplastic resin.

First claim

What is claimed is:

1. An electronic device, comprising:
a case formed of an ultra-light fabric material;
a frame coupled to the case and supporting the case; and
a face pad coupled to the frame,
wherein ultra-light fabric material comprising:
an ultra-light material comprising a thermoplastic resin and a core material dispersed in thermoplastic resin; and
a fabric thermo-compressed on at least one side of the ultra-light material by thermoplastic resin,
wherein the frame includes a support for preventing sagging in the case due to external force,
wherein the face pad includes a face contact portion and a case assembly portion,
wherein the face contact portion includes a first foam and a first fabric integrated with the first foam,
wherein the case assembly portion includes a second foam and a second fabric integrated with the second foam, and
wherein the face contact portion and the case assembly portion are bonded by a bonding film.

2. The electronic device of claim 1 , wherein the fabric is thermally compressed to an outer surface of the ultra-light material, bent to surround an edge of the ultra-light material, and the end of the fabric is bonded to an inner surface of the ultra-light material.

3. The electronic device of claim 1 , wherein the fabric is thermo-compressed to an outer surface of the ultra-light material, the end of the ultra-light material and the end of the fabric are bent.

4. The electronic device of claim 1 , wherein the fabric is thermo-compressed to an outer surface of the ultra-light material, the end of the ultra-light material and the end of the fabric are covered by a finishing member.

5. The electronic device of claim 4 , wherein a height of the finishing member is larger than a thickness of the ultra-light fabric material.

6. The electronic device of claim 4 , wherein a height of the finishing member is the same as a thickness of the ultra-light fabric material.

7. The electronic device of claim 1 , wherein the fabric is thermo-compressed to an outer surface of the ultra-light material, the ultra-light material includes a rounded end.

8. The electronic device of claim 1 , wherein hardness of the first foam is lower than hardness of the second foam.

9. The electronic device of claim 8 , wherein the face contact portion of the face pad includes a forehead contact portion in contact with a user's forehead and a cheek contact portion in contact with the user's cheek, and
a curvature of the forehead contact portion is different from a curvature of the cheek contact portion.

10. The electronic device of claim 9 , wherein the curvature of the forehead contact portion is smaller than the curvature of the cheek contact portion.

11. The electronic device of claim 9 , wherein the face pad further includes a light leakage prevention portion extending from the cheek contact portion.

12. The electronic device of claim 11 , wherein a distance between the end of the light leakage prevention portion and the user's eyes is equal to or more than 5 cm.

13. The electronic device of claim 11 , wherein a width of the forehead contact portion is formed larger than a width of the light leakage prevention portion.
