Abstract
Abstract A headset includes a body comprising a chin portion extending to enlarged ear portions. Each ear portion includes an earpad receiving opening defined by an annular rim. An earpad is mounted in each earpad receiving opening of the headset body and comprises an ear engaging layer extending to a cylindrical ear surrounding portion which encloses an annular cushioning member. Each earpad further comprises a retaining portion which encloses an annular retaining member formed from a relatively rigid material. The ear surrounding and retaining portions of each earpad are separated by a groove which receives the annular rim of one of the earpad receiving openings of the headset body, whereby the earpads are detachably secured to the headset body.

The method of fabricating a headset according to claim 1 wherein the step of positioning a retaining member in the retaining portion of each earpad is carried out by joining the ends of two lengths of relatively rigid plasTic material to form a pair of annular retaining members, and positioning the annular retaining members in the retaining portions of the earpads.
Claim 4
Dependent Claim
47 words
The method of fabricating a headset according to claim 2 wherein each annular retaining member is formed by forming at least one pointed end on a length of plastic tubing material into the interior of the opposite end of the material to form the annular retaining member.
Claim 5
Dependent Claim
65 words
The method of fabricating a headset according to claim 3 wherein the step of positioning a cushioning member in the ear surrounding portion of each earpad is carried out by threading a length of relatively resilient plastic material into the ear surrounding portion of each earpad and thereby forming an annular cushioning member extending around the periphery of the ear engaging layer of each earpad.
Claim 6
Dependent Claim
57 words
The method of fabricating a headset according to claim 4 further including the step of bonding the inner layer of each earpad to the ear engaging layer thereof subsequent to the positioning of the cushioning and retaining members in the earpad and prior to mounting of the earpad in the earpad receiving opening of the headset body.
Claim 7
Independent Claim
122 words
A method of making an earpad comprising: forming an earpad blank comprising an ear engaging layer extending to a cylindrical ear surrounding portion, a cylindrical retaining portion, and a groove separating the ear surrounding and retaining portions; mounting an annular cushioning member in the ear surrounding portion of the earpad blank so that the cushioning member extends around the periphery of the ear engaging layer; and mounting an annular retaining member in the retaining portion of the earpad blank and thereby forming an earpad which is adapted for mounting in a headset having an earpad receiving opening defined by a rim by receiving the rim in the groove of the earpad with the retaining portion of the earpad positioned behind the rim.
Claim 8
Independent Claim
122 words
A method of making an earpad comprising: forming an earpad blank comprising an ear engaging layer extending to a cylindrical ear surrounding portion, a cylindrical retaining portion, and a groove separating the ear surrounding and retaining portions; mounting an annular cushioning member in the ear surrounding portion of the earpad blank so that the cushioning member extends around the periphery of the ear engaging layer; and mounting an annular retaining member in the retaining portion of the earpad blank and thereby forming an earpad which is adapted for mounting in a headset having an earpad receiving opening defined by a rim by receiving the rim in the groove of the earpad with the retaining portion of the earpad positioned behind the rim.
Claim 9
Dependent Claim
66 words
The method of making an earpad according to claim 6 wherein the step of mounting an annular retaining member in the retaining portion of the earpad blank is carried out by joining the ends of a length of relatively rigid plastic tubing material to form the annular retaining member, and subsequently positioning the annular retaining member thus formed in the retaining portion of the earpad blank.
Claim 10
Dependent Claim
83 words
The method of making an earpad according to claim 7 wherein the step of mounting an annular cushioning member in the ear surrounding portion of the earpad blank is further characterized by threading a normally straight length of relatively resilient plastic material into the ear surrounding portion of the earpad blank whereby the resiliency of the length of resilient material maintains the cushioning member in engagement with the interior of the ear surrounding portion of the earpad blank and in the annular configuration.
Claim 11
Dependent Claim
74 words
The method of making an earpad according to claim 8 wherein the step of forming an earpad blank is further characterized by forming a layer disposed oppositely from the ear engaging layer and having an aperture formed through it and wherein the cushioning member and retaining member mounting steps are carried out by inserting the cushioning member and the retaining member into the interior of the earpad blank through the aperture in said layer.
Claim 12
