Modular in-the-ear hearing aid

Claim 2

An in-the-ear hearing aid comprising: a modular unit contained within a housing of standardized configuration and providing a wholly operable instrument, said housing including: a mounting plate for attachment of said housing to an ear mold, and a coupler for acoustic connection of the receiver of the hearing aid to the exit aperture of the ear mold, said coupler being removably attached to said housing and having an output tube outwardly extending in predetermined angular relation to said housing; an ear mold adapted to fit the ear cavity of a user and having a recessed area onto which is secured the mounting plate of said housing for attachment of said housing to said ear mold, and a tip portion adapted to extend into the ear canal of a user and having an opening therethrough terminating in an exit aperture; means for securing said housing to the recessed area of said ear mold; and a flexible tubing extending through the opening in said tip portion of the ear mold and connected at one end to the output tube of said coupler and terminating at the other end at said exit aperture of the ear mold.

Claim 3

The hearing aid of claim 1 wherein said housing includes an opening in a side wall thereof and a mounting configuration around the periphery of said opening; and wherein said coupler includes a plate having a periphery cooperative with the mounting configuration of said opening for removable attachment to said housing.

Claim 4

The hearing aid of claim 1 wherein said coupler includes a plate having a flange around the periphery thereof, said output tube being outwardly extending from said plate at a predetermined angle thereto; said housing having an opening in a wall thereof and a groove provided around the periphery of the opening into which said flange is slidably disposed.

Claim 5

The hearing aid of claim 3 wherein said mounting plate includes a portion retaining the plate of said coupler in the groove of said housing with the mounting plate secured to the housing.

Claim 6

The hearing aid of claim 1 wherein said ear mold includes a vent opening through the tip portion thereof communicating between an opening adjacent said exit aperture and an opening at the exterior of the ear mold.

Claim 7

An in-the-ear hearing aid comprising: a modular unit contained within a housing of standardized configuration and providing a wholly operable instrument, said housing including: a plurality of threaded inserts secured in the wall of said housing; a substantially flat mounting plate threadably secured to said housing and adapted for attachment of said housing to an ear mold, and a coupler for acoustic connection of the receiver of the hearing aid to the exit aperture of the ear mold, said coupler having a peripheral flange for removable attachment within a groove in a portion of the wall of said housing and having an output tube outwardly extending in predetermined angular relation to said housing; an ear mold adapted to fit the ear cavity of a user and having a substantially flat recessed area onto which is threadably secured the mounting plate of said housing for attachment of said housing to said ear mold, and a tip portion adapted to extend into the ear canal of a user and having an opening therethrough terminating in an exit aperture and a vent opening therethrough communicating with the exterior of said ear mold; and a flexible tubing extending through the opening in the tip portion of said ear mold and connected at one end to the output tube of said coupler, and terminating at the other end at the exit aperture of said ear mold.

Claim 8

An in-the-ear hearing aid comprising: a modular unit contained within a housing of standardized configuration and providing a wholly operable instrument, said housing including: a plurality of threaded inserts secured in the wall of said housing; a substantially flat mounting plate threadably secured to said housing and adapted for attachment of said housing to an ear mold, and a coupler for acoustic connection of the receiver of the hearing aid to the exit aperture of the ear mold, said coupler having a peripheral flange for removable attachment within a groove in a portion of the wall of said housing and having an output tube outwardly extending in predetermined angular relation to said housing; an ear mold adapted to fit the ear cavity of a user and having a substantially flat recessed area onto which is threadably secured the mounting plate of said housing for attachment of said housing to said ear mold, and a tip portion adapted to extend into the ear canal of a user and having an opening therethrough terminating in an exit aperture and a vent opening therethrough communicating with the exterior of said ear mold; and a flexible tubing extending through the opening in the tip portion of said ear mold and connected at one end to the output tube of said coupler, and terminating at the other end at the exit aperture of said ear mold.
