Ear insert for hearing aids
View Patent ↗Active otoplastics ( 3 ) with integrated earpieces ( 4 ) are to be acoustically optimized. There is provision here for forming a sound outlet ( 8 ) into the otoplastic in accordance with acoustic conditions. If the sound outlet ( 8 ) has the form of an exponential horn, this results in advantages for supply of high tones. The earpiece ( 4 ) can be secured with the aid of an adapter ( 5 ) into the otoplastic ( 3 ) so that it can be exchanged.
1. An ear insert for a hearing aid, comprising:
a molded padding sized and configured to fit into an auditory canal and having a cavity;
a cap for covering the cavity at a side of the cavity facing away from an eardrum of the auditory canal when the ear insert is fit into the auditory canal;
an acoustic earpiece arranged within the cavity, detachable from the molded padding and adapted to provide sound to the auditory canal; and
a sound outlet operatively connected to the acoustic earpiece and configured to face the eardrum when the ear insert is fit into the auditory canal, wherein the sound outlet is at least partially included in a capsule accommodating the acoustic earpiece and shaped as an element chosen from the group consisting of a funnel and an exponential horn.
2. The ear insert according to claim 1 , wherein the sound outlet comprises a first and a second opening, the first opening facing the eardrum, the second opening facing the acoustic earpiece and the first opening having a larger area than the second opening.
3. The ear insert according to claim 1 , wherein the capsule is adapted to be inserted into and detached from the molded padding from a side of the molded padding facing the eardrum when the molded padding is inserted into the auditory canal.
4. The ear insert according to claim 1 , wherein the molded padding is a fitting piece sized and configured to match the auditory canal.
5. The ear insert according to claim 1 , wherein the acoustic earpiece is connected to an external sound processing device using the cap.
6. The ear insert according to claim 5 , wherein an contact spring is attached to the acoustic earpiece and the capsule for connecting the acoustic earpiece to an external sound processing.
7. The ear insert according to claim 6 , wherein the contact spring is also attached to the cap.
8. The ear insert according to claim 1 , wherein the acoustic earpiece comprises the cap.
