Abstract
Official abstract text for this publication.
Provided is a headphone unit including a housing having a convex portion and accommodating a driver unit, a support in contact with part of the outer surface of the convex portion, and a frictional member in contact with the support and the outer surface of the convex portion. The frictional member generates greater friction against the convex portion than the friction between the support and the convex portion. The housing is swingably joined to the support.
First claim
Opening claim text (preview).
What is claimed is: 1. A headphone unit comprising: a housing having a convex portion and accommodating a driver unit; a support having a contact surface in contact with part of an outer surface of the convex portion; a frictional member in contact with the support and the outer surface of the convex portion, the frictional member generating greater friction against the convex portion than the friction generated between the support and the convex portion; and a stop in contact with an inner surface of the convex portion, wherein the housing is swingably joined to the support, the housing comprises a hole extending through the convex portion, the support comprises a first protrusion extending through the hole of the housing, and wherein the first protrusion of the support is in contact with the stop. 2. The headphone unit according to claim 1 , wherein the outer surface of the convex portion, the contact surface of the support in contact with the outer surface of the convex portion, and an outer surface of the stop in contact with the inner surface of the convex portion are spherical surfaces concentrically aligned. 3. The headphone unit according to claim 1 , wherein a gap is defined between the periphery of the hole and the first protrusion of the support. 4. The headphone unit according to claim 1 , wherein the angle between the housing and the support is adjustable. 5. The headphone unit according to claim 1 , wherein kinetic friction is generated between the frictional member and the housing when the housing swings relative to the support. 6. The headphone unit according to claim 1 , wherein the frictional member is an elastic ring surrounding a contact portion between the housing and the support. 7. The headphone unit according to claim 1 , wherein the support comprises a second protrusion on a surface facing the housing, and the housing comprises a receiving hole larger in outer perimeter than the second protrusion so as to receive the second protrusion in the receiving hole. 8. An ear muff unit comprising: a housing having a convex portion; a support in contact with part of an outer surface of the convex portion; a frictional member in contact with the support and the outer surface of the convex portion, the frictional member generating greater friction against the convex portion than the friction generated between the support and the convex portion; and a stop in contact with an inner surface of the convex portion, wherein the housing is swingably joined to the support, the housing comprises a hole extending through the convex portion, the support comprises a first protrusion extending through the hole of the housing, and wherein the first protrusion of the support is in contact with the stop.
