Abstract

In an electroacoustic transducer ( 21 ) with a stationary transducer part ( 23 ) and with a membrane configuration ( 17 ) comprising a membrane ( 15 ) and a handling ring ( 1 ) for the membrane ( 15 ) connected with the membrane ( 15 ), the membrane configuration ( 17 ) is connected with the stationary transducer part ( 23 ) via the handling ring ( 1 ), and the handling ring ( 1 ) and membrane ( 15 ) are connected together via an interlocking connection.

Claims (7)

1. A deep-drawing method of forming a membrane for use in an electroacoustic transducer, the deep-drawing method using a deep-drawing mold having an annular limiting mold surface, the method comprising:

placing a rigid membrane-support member for the electroacoustic transducer in the deep-drawing mold to rest against the annular limiting mold surface;

inserting a membrane-material into the deep-drawing mold and shaping the membrane-material into a membrane having an interlocking connection with the rigid membrane-support member, the interlocking connection preventing relative movement between the membrane and the rigid membrane-support member; and

removing excess membrane-material from the membrane.

2. The deep-drawing method of claim 1 wherein removing excess membrane material includes using a laser to remove the excess membrane-material.

3. The deep-drawing method of claim 1 wherein the rigid membrane-support member is a handling ring.

4. The deep-drawing method of claim 1 wherein the membrane-material is a piece of foil.
