Abstract
Abstract A hearing aid has a housing insertable into the auditory canal, wherein the housing contains at least a microphone, an amplifier, an earpiece and a power source. In instruments of this kind it has turned out to be desirable to have, in addition to the usual volume control, an additional control for varying the way the incoming sound signals are influenced by the amplifier (i.e. its characteristic) to adapt to individual hearing impairments. For this purpose the hearing aid provides in the housing space for the battery a pitch control in such a manner that its actuating member can be operated at least when the power source is removed from the instrument. This makes it possible to reduce the space requirement for the pitch control so that even hearing aids insertable into the auditory canal can contain such an additional control.

Claim 1
Independent Claim
136 words
A hearing aid with a housing having a shape adapted for insertion into an outer auditory canal which includes a microphone, an amplifier, a receiver and a power source, the housing having a generally frustoconical shape including a planar base portion serving as an exposed wall when the hearing aid is in the outer auditory canal, the exposed wall having an aperture and cover, the cover adapted to close over the aperture and including retaining means on its inner side for accepting and securing the power source, a recess in the housing adapted to contain the retaining means, said recess being accessible via the aperture, a control having an actuating member mounted in said recess in a location to provide access to the actuating member such that it can be adjusted when the cover is opened.
Claim 2
Dependent Claim
136 words
A hearing aid with a housing having a shape adapted for insertion into an outer auditory canal which includes a microphone, an amplifier, a receiver and a power source, the housing having a generally frustoconical shape including a planar base portion serving as an exposed wall when the hearing aid is in the outer auditory canal, the exposed wall having an aperture and cover, the cover adapted to close over the aperture and including retaining means on its inner side for accepting and securing the power source, a recess in the housing adapted to contain the retaining means, said recess being accessible via the aperture, a control having an actuating member mounted in said recess in a location to provide access to the actuating member such that it can be adjusted when the cover is opened.
Claim 3
Dependent Claim
27 words
The hearing aid according to claim 1, wherein the cover is pivotably attached at the aperture and the control is located in a sidewall within the recess.
Claim 4
Dependent Claim
23 words
The hearing aid according to claim 1, wherein the control is mounted to a contact spring connecting the power source to the amplifier.
Claim 5
Dependent Claim
26 words
The hearing aid according to claim 1, wherein the recess includes interior walls and wherein the control actuating member is mounted on an inclined interior wall.
Claim 6
Dependent Claim
154 words
A hearing aid of the type having an amplifier within a housing having a generally conical shape suitable for insertion into an outer auditory canal, said housing comprising a base serving as a face plate and being the exposed portion of the housing when inserted into the outer auditory canal; an aperture in said face plate and a recess within the housing accessible via the aperture, the recess having a bottom portion; a cover pivotally mounted for covering the aperture; a power source; the cover having a holder on its inner side adapted to retain the power source such that when the cover is closed, the holder including the power source is located and enclosed in the recess; and a pitch control having an actuating member, said pitch control being mounted to have its actuating member located in the recess to provide access to the actuating member for adjusting when the cover is opened.
Claim 7
Dependent Claim
154 words
A hearing aid of the type having an amplifier within a housing having a generally conical shape suitable for insertion into an outer auditory canal, said housing comprising a base serving as a face plate and being the exposed portion of the housing when inserted into the outer auditory canal; an aperture in said face plate and a recess within the housing accessible via the aperture, the recess having a bottom portion; a cover pivotally mounted for covering the aperture; a power source; the cover having a holder on its inner side adapted to retain the power source such that when the cover is closed, the holder including the power source is located and enclosed in the recess; and a pitch control having an actuating member, said pitch control being mounted to have its actuating member located in the recess to provide access to the actuating member for adjusting when the cover is opened.
Claim 8
Dependent Claim
27 words
A hearing aid according to claim 5, wherein the cover is hinged to the housing to provide the pivotal mounting and the power source comprises a battery.
Claim 9
Dependent Claim
167 words
A miniature hearing aid of the type having a generally conical shaped housing for insertion into an outer auditory canal, the hearing aid comprising a microphone, an amplifier having an associated volume control, a receiver, and a power source cooperating together to receive and amplify sound impinging on the auditory canal, the generally conical shaped housing having a base serving as an exposed face plate when the hearing aid is located in the auditory canal, the face plate including a pivotably attached cover over an aperture and a recess which is accessed by pivoting the cover in an open position, the cover including holding means for securing the power source on the inner side of the cover, wherein accessing the recess by pivoting the cover also removes the holding means including the power source from the recess, and a pitch control in a location in the recess for controlling the amplifier, and the location being accessible to enable adjustment of the pitch control by opening the cover.
Claim 10
Dependent Claim
167 words
A miniature hearing aid of the type having a generally conical shaped housing for insertion into an outer auditory canal, the hearing aid comprising a microphone, an amplifier having an associated volume control, a receiver, and a power source cooperating together to receive and amplify sound impinging on the auditory canal, the generally conical shaped housing having a base serving as an exposed face plate when the hearing aid is located in the auditory canal, the face plate including a pivotably attached cover over an aperture and a recess which is accessed by pivoting the cover in an open position, the cover including holding means for securing the power source on the inner side of the cover, wherein accessing the recess by pivoting the cover also removes the holding means including the power source from the recess, and a pitch control in a location in the recess for controlling the amplifier, and the location being accessible to enable adjustment of the pitch control by opening the cover.
Claim 11
Dependent Claim
