Method for establishing a detachable mechanical and/or electrical connection
View Patent ↗An electrical connection to or in a hearing apparatus is established by assembling a series capacitor. The capacitor is formed by one part having one capacitor plate and a second part having another capacitor plate. A part of the casing of the hearing apparatus can be used as a dielectricum of the capacitor.
1. A hearing apparatus with a detachable electric connection, said connection comprising a capacitance, a part of a casing of said hearing apparatus forming a dielectricum of said capacitance, and further comprising one conductive plate of said capacitance in contact with said part, a thickness of said part contacting said plate being smaller than a thickness of said part adjacent said plate.
2. The apparatus of claim 1 , wherein said part is of a material which is equal to a material of said casing adjacent said part.
3. The apparatus of claim 1 , wherein said electric connection is a connection to the outside of said hearing apparatus.
4. The apparatus of claim 3 , wherein said electric connection is a connection to one of a cable and of a body of an individual carrying said apparatus.
5. The apparatus of claim 4 , wherein said cable is a one-lead cable.
6. The apparatus of claim 1 , wherein said electrical connection is operationally connected to an optical cable.
7. The apparatus of claim 1 , wherein said electric connection is detachably held together by means of cooperating magnetic parts.
8. The apparatus of claim 7 , further comprising guiding members ensuring proper alignment of said capacitance when establishing said electric connection.
9. The apparatus of claim 1 , wherein said part forming said dielectricum has a surface exposed to ambient whenever said detachable electric connection is detached.
10. The apparatus of claim 9 , wherein said surface of said part is flush with an outer surface of said casing adjacent said part.
11. The apparatus of claim 1 , wherein said apparatus comprises a contact electrode exposed to ambient at an area of said hearing apparatus contacting a human body when carried by an individual and wherein said electrode is a reference potential electrode for electronics of said hearing apparatus.
12. The apparatus according to claim 1 , wherein said detachable connection establishes an electric connection to a one-lead cable connectable to a second hearing apparatus and wherein there is provided at said one apparatus a reference potential electrode at an outer surface of said casing contacting a human body.
13. The apparatus of claim 12 , wherein said reference potential electrode comprises a capacitance plate, a dielectrical material covering said plate and having a surface exposed to ambient.
14. The apparatus of claim 1 being a hearing aid apparatus.
15. The apparatus of claim 1 being an outside-the-ear or an inside-the-ear hearing apparatus.
16. The apparatus of claim 1 , further comprising a remote transmitter module operationally connectable to said hearing apparatus via said detachable connection.
17. The apparatus of claim 1 , further comprising a remote control unit for said hearing apparatus being connectable to said hearing apparatus via said detachable connection.
18. The apparatus of claim 1 , further comprising a second hearing apparatus, said one and said second apparatus being interconnected via said detachable connection.
