Earpiece for acoustic headset
| Details |
Inventors: Shore, Sidney X.; Martin, Paul S.;
Assignee:
Primary Examiner: Brown; Thomas W.
Assistant Examiner:
Attorney, Agent or Firm:
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. |

DETAILED DESCRIPTION What is claimed is: 1.
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.
2.
An earpiece in accordance with claim 1, wherein at least certain of said ribs are interconnected by webs.
3.
An earpiece in accordance with claim 2, wherein the interconnecting webs slope as the flange is viewed in circular cross-section.
4.
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.
5.
The earpiece in accordance with claim 4, wherein the separated ribs are of reduced thickness along their margins to form narrow marginal webs.
6.
The earpiece in accordance with claim 5, wherein the marginal webs at the edges of a slot are staggered.
7.
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.
8.
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.
9.
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.
10.
The earpiece in accordance with claim 1, further including a resilient tubular projection that extends the through passage beyond the flange.
11.
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
