Abstract
Abstract A hearing aid device comprising an ear insert or ear mold which has a hole formed therethrough communicating with the channel in the wearer''s ear. A precision metal fitting or adapter is made of tubular material and is installed in the outer end of said hole by heating the fitting or adapter and sweating it into said hole thereby eliminating the use of plastic tubing in the ear mold and the use of cements or adhesives. A plastic tube leading to the conventional hearing aid amplifier is attached to this fitting. In one embodiment of this invention the fitting or adapter is provided with a vented, threaded arm with means to open or close the vents thereof to facilitate tuning of the hearing aid channel and release air pressure therefrom.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
The method of making a hearing aid device comprising the steps of providing an ear insert of thermoplastic material, forming a hole through said insert which is adapted to communicate with the auditory canal of the ear of the wearer thereof, providing a tubular connection to said hole, roughening a portion of the outside of said tubular connection, heating said roughened portion and while it is hot inserting it into the outer end of said hole to seal it thereto and attaching a tube to said tubular connection for transmitting sound from the output of the hearing aid amplifier thereto.
Claim 2
Independent Claim
100 words
The method of making a hearing aid device comprising the steps of providing an ear insert of thermoplastic material, forming a hole through said insert which is adapted to communicate with the auditory canal of the ear of the wearer thereof, providing a tubular connection to said hole, roughening a portion of the outside of said tubular connection, heating said roughened portion and while it is hot inserting it into the outer end of said hole to seal it thereto and attaching a tube to said tubular connection for transmitting sound from the output of the hearing aid amplifier thereto.
Claim 3
Dependent Claim
123 words
In a hearing aid, the combination of an ear insert of thermo-plastic material, said ear insert having a hole therethrough opening into the auditory canal of the ear when said insert is positioned in the wearer''s ear, a tubular member, one end portion of said tubular member having a knurled outer surface, said knurled outer surface of said tubular member being inserted into the outer end portion of said hole when said member is at a temperature such that said knurled surface is heat sealed in said hole and the hole through said tubular member communicates with said hole through said plastic insert and a tube attached to the outer end portion of said tubular member connecting it to a hearing aid amplifier.
Claim 4
Dependent Claim
123 words
In a hearing aid, the combination of an ear insert of thermo-plastic material, said ear insert having a hole therethrough opening into the auditory canal of the ear when said insert is positioned in the wearer''s ear, a tubular member, one end portion of said tubular member having a knurled outer surface, said knurled outer surface of said tubular member being inserted into the outer end portion of said hole when said member is at a temperature such that said knurled surface is heat sealed in said hole and the hole through said tubular member communicates with said hole through said plastic insert and a tube attached to the outer end portion of said tubular member connecting it to a hearing aid amplifier.
Claim 5
Dependent Claim
65 words
In a hearing aid, the combination as set forth in claim 2, further characterized in that said tubular member is provided with vent means and a member threaded into said tubular member to at least partially open or close said vent means to control the range of sound frequencies transmitted to the wearer''s ear and also to control the air pressure in the wearer''s ear.
