US Patent:

Filed:
Jun 20, 2011
Appl. No.:
13/134840
Inventors:
John W. Davis - The Villages FL, US
International Classification:
H04R 25/00
US Classification:
381328
Abstract:
A metal retainer spring bent into a forwardly tapered flexible spring for retaining an acoustic ear tube for use with behind-the-ear devices. A rearward hook or tapering slot holds the acoustic ear tube with a friction fit. A forward opening admits the acoustic ear tube therethrough to transmit sound to the eardrum. The ear canal-contacting surfaces of each spring have a friction surface to limit slippage without causing abrasions.
