Acoustic Ear Tube Retainer Spring
US Patent:
2009004, Feb 12, 2009
Filed:
Aug 8, 2007
Appl. No.:
11/891012
Inventors:
John W. Davis - South Windsor CT, US
International Classification:
H04R 25/00
US Classification:

Abstract:
A metal retainer spring bent into a U-shape retains an acoustic ear tube for use with behind-the-ear devices. The tube is held by a tube retaining opening in a tapered mid portion, forming the curved portion of the bent spring, and end slots bent together with the slots holding the tube. The retainer spring fits into the human ear canal for securing a narrow acoustic ear tube within a user's ear canal. The spring is manufactured from beryllium copper, or other material with excellent strength and great elasticity, and is then gold plated for the hypoallergenic properties. The top and bottom ear canal-contacting surfaces of each spring have a pebbled or rippled finish to limit slippage without causing abrasions.
