Abstract
Abstract An earpiece having a tubular hub for receiving a sound-transmitting tube has a flange on an end of the hub about a central passage, comprising radiating ribs which are mutually separated by radiating slots or by webs. More particularly, the webs slope and the ribs adjoining the slots have marginal webs that are staggered in relation to each other, all as viewed in circular cross-section centered about the central passage. Still further, a tubular projection extends the central passage beyond the flange.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
80 words
An earpiece for an acoustic headset proportioned for cooperating with the wearer's outer ear at the ear canal, said earpiece comprising a tubular portion having a through passage for sound transmission and for receiving an acoustic tube and having a flange portion on an end of the tubular portion, said flange portion being subdivided so as to comprise a plurality of ribs radiating from the tubular portion, the ribs being normally separated by radiating regions of at least reduced thickness.
Claim 2
Dependent Claim
80 words
An earpiece for an acoustic headset proportioned for cooperating with the wearer's outer ear at the ear canal, said earpiece comprising a tubular portion having a through passage for sound transmission and for receiving an acoustic tube and having a flange portion on an end of the tubular portion, said flange portion being subdivided so as to comprise a plurality of ribs radiating from the tubular portion, the ribs being normally separated by radiating regions of at least reduced thickness.
Claim 3
Dependent Claim
18 words
An earpiece in accordance with claim 1, wherein at least certain of said ribs are interconnected by webs.
Claim 4
Dependent Claim
20 words
An earpiece in accordance with claim 2, wherein the interconnecting webs slope as the flange is viewed in circular cross-section.
Claim 5
Dependent Claim
27 words
An earpiece in accordance with claim 1, wherein at least certain of the radiating ribs are separated along at least part of their lengths by radiating slots.
Claim 6
Dependent Claim
23 words
The earpiece in accordance with claim 4, wherein the separated ribs are of reduced thickness along their margins to form narrow marginal webs.
Claim 7
Dependent Claim
19 words
The earpiece in accordance with claim 5, wherein the marginal webs at the edges of a slot are staggered.
Claim 8
Dependent Claim
43 words
The earpiece in accordance with claim 1, wherein groups of at least two of said radiating ribs per group are separated by radiating slots, and wherein each rib of each group is connected to the adjacent rib of the group by a web.
Claim 9
Dependent Claim
31 words
The earpiece in accordance with claim 7, wherein the ribs which are separated by slots have marginal webs that are staggered in relation to each other as viewed in circular cross-section.
Claim 10
Dependent Claim
24 words
The earpiece in accordance with claim 8, wherein said interconnecting webs slope as the flange is viewed in a circular cross-section about its center.
Claim 11
Dependent Claim
21 words
The earpiece in accordance with claim 1, further including a resilient tubular projection that extends the through passage beyond the flange.
Claim 12
Dependent Claim
81 words
An earpiece for an acoustic headset proportioned for cooperating with the wearer's outer ear at the ear canal, said earpiece comprising a tubular portion adapted at one end thereof for connection to an acoustic tube and having a through passage for sound transmission, said earpiece also comprising a flange at a position spaced from said one end thereof, said flange being divided by regions of at least reduced thickness into a plurality of elements extending outward relative to said tubular portion.
Claim 13
Dependent Claim
81 words
An earpiece for an acoustic headset proportioned for cooperating with the wearer's outer ear at the ear canal, said earpiece comprising a tubular portion adapted at one end thereof for connection to an acoustic tube and having a through passage for sound transmission, said earpiece also comprising a flange at a position spaced from said one end thereof, said flange being divided by regions of at least reduced thickness into a plurality of elements extending outward relative to said tubular portion.
Claim 14
Dependent Claim
35 words
An earpiece in accordance with claim 11, wherein in the condition of the earpiece when not worn, said flange extends from said tubular portion progressively outward and toward the plane of said one end thereof.
Claim 15
Dependent Claim
22 words
An earpiece in accordance with claim 11, wherein said flange has webs interconnecting said elements at least at certain of said regions.
Claim 16
Dependent Claim
24 words
An earpiece in accordance with claim 11, wherein at least certain of said regions comprise slots extending outward in relation to said tubular portion.
Claim 17
Dependent Claim
56 words
An earpiece in accordance with claim 11, wherein at least certain of said regions comprise slots, each pair of elements divided by a slot having webs that are staggered in relation to each other as viewed in circular cross-section about the axis of the tubular portion for becoming overlapped when the elements are deformed in use.
Claim 18
Dependent Claim
24 words
An earpiece in accordance with claim 11, wherein said tubular portion extends beyond the flange in the direction remote from said one end thereof.
