Process for a diaphragm for electroacoustic transducers |
| abstract |
A diaphragm for an electroacoustic transducer has a) a core layer containing poly(meth)acrylimide foam and b) at least one cover layer. The diaphragm is produced by laminating the cover layer with the core layer, using a pressure of 0.4 MPa and a temperature of 160° C., whereby at least the side of the core layer which comes into contact with the cover layer is compressed. The resultant composite is subsequently cooled to a temperature below 80° C., before the pressure is reduced to the ambient pressure. The process can be carried out as a single-step process. The diaphragms produced by this process demonstrate an excellent stability, whereby the cover layers in particular are highly resistant to separation. |
