12. The method of claim 7 , wherein said trimming step includes trimming said base plate to continue a contour of said housing.

13. A method of manufacturing a hearing device, comprising the steps of:

providing a housing having an opening;

providing an electric/acoustic transducer;

providing a support plate forming a blind hole having a membrane as a base;

inserting said transducer into said blind hole, wherein an extending portion of said transducer extends from said blind hole out of said base plate;

bringing said housing and said support plate together such that said extending portion enters through said opening of said housing;

bonding said housing to said support plate; and

trimming an excess portion of said support plate to continue a contour of said housing and to form an acoustic opening to be utilized as an acoustic output of said hearing device, wherein

said membrane forms a freely vibrating membrane covering said acoustic opening.

14. The method of claim 13 , wherein said membrane is integral with said support plate and formed from the same material as said support plate.

15. The method of claim 14 , wherein said support plate includes elastomeric material.

16. The method of claim 13 , wherein said membrane is formed by depositing an elastomeric sheet over a hole through said base plate, and bonding said sheet to said base plate, thereby forming said blind hole.

17. A method of manufacturing a hearing device, said hearing device comprising:

a housing including a part forming an acoustic opening;

an electric/acoustic transducer including:

a diaphragm;

an electric drive coupled to said diaphragm; and

an encapsulation comprising said part of said hearing aid housing; and

a freely vibrating membrane at least substantially flush with an outer surface of said part and facing a surrounding of said hearing aid, wherein

said acoustic opening establishes acoustical communication between said diaphragm and the surrounding of said hearing aid, and further wherein

said acoustic opening is covered by said freely vibrating membrane; wherein said method comprises the steps of:

providing a support plate forming a blind hole having said membrane as a base;

inserting said transducer into said blind hole, wherein an extending portion of said transducer extends from said blind hole out of said base plate;

bringing said housing and said support plate together such that said extending portion enters said housing;

bonding said housing to said support plate; and

trimming an excess portion of said support plate to form said part.

18. The method of claim 17 , wherein said membrane is integral with said support plate and formed from the same material as said support plate.

19. The method of claim 18 , wherein said support plate includes elastomeric material.

20. The method of claim 17 , wherein said membrane is formed by depositing an elastomeric sheet over a hole through said base plate, and bonding said sheet to said base plate, thereby forming said blind hole.

21. A method of manufacturing a hearing device, comprising the steps of:

providing a hearing aid housing having an opening;

providing an electric/acoustic transducer;

providing a support plate forming a blind hole having a membrane as a base;

inserting said transducer into said blind hole, wherein said transducer is held within said blind hole by frictional means;

bringing said housing and said support plate together such that a portion of said transducer enters through said opening of said housing, wherein said transducer is held within said housing by frictional means;

bonding said housing to said support plate; and

trimming an excess portion of said support plate.
