Abstract
This invention discloses an ear tip used in connection with a stethoscope. Whereby the disclosed ear tip is formed of a single piece of molded elastomeric material that is inverted and sealed to form a sealed chamber that is filled with a liquid gelatin, whereby standard loads deform the liquid gelatin filled cavity under principles of displacement providing for the ear tips capability of contouring to the infinite variations and configurations of different outer ear canals, and thereby creating a complete acoustic seal between the outer surface of the ear tip and the outer ear of the user. Furthermore, this invention discloses a means of attachment to a listening device that facilitates the attachment and removal of the ear tip to the listening device.
