Abstract
In order to use the residual hearing in patients indicated for a cochlear implant (CI), it is advantageous to supplement the electrical stimulation of the cochlear implant with an acoustic stimulation. Such residual hearing is usually present in a frequency range below one kilohertz.
Claims46
An electroacoustic transducer for implantation into an ear, comprising:
- an inner ear housing;
- at least one sound transducer;
- and
- a middle ear component;
- wherein the inner ear housing surrounds an inner ear area, which is adjacent to the sound transducer and delimited by the sound transducer, wherein the middle ear component is arranged on a side of the sound transducer opposite the inner ear area, wherein the inner ear housing has at least one sound transmission window, which is incorporated into at least one wall of the inner ear housing, and through which vibrations may be transmitted, and wherein the inner ear housing is configured so that it is insertable into an opening between a middle ear and an inner ear of a person, such that the inner ear area projects at least partially into the inner ear so that the at least one sound transmission window is located in the inner ear.

An electroacoustic transducer for implantation into an ear, comprising:
- an inner ear housing;
- at least one sound transducer;
- and
- an electrode carrier with at least one electrode arranged on a surface of the electrode carrier;
- wherein the inner ear housing surrounds an inner ear area, which is adjacent to the sound transducer and delimited by the sound transducer, wherein the inner ear housing has at least one sound transmission window, which is incorporated into at least one wall of the inner ear housing, and through which vibrations may be transmitted, wherein the inner ear housing is configured such that it is insertable into an opening between a middle ear and an inner ear of a person, such that the inner ear area projects at least partially into the inner ear such that the at least one sound transmission window is located in the inner ear, and wherein the electrode carrier extends from the inner ear area in a direction away from the sound transducer.
