Method for producing membranes for electroacoustic transducers and membranes obtained by this method |
| abstract |
The invention relates to a method for producing a membrane for electroacoustic transducers, comprising a core layer (3) consisting of poly(meth)acrylimide foam and at least one cover layer (4). The cover layer (4) is laminated with the core layer (3), using a pressure >/= 0.4 MPa and a temperature >/= 160 DEG C, whereby at least the side of the core layer (3) which comes into contact with the cover layer (4) is compressed. The resultant composite is subsequently cooled to a temperature below 80 DEG C, before the pressure is reduced to the ambient pressure. The method can be carried out as a single-step process. The membranes produced by the inventive method demonstrate an excellent stability, whereby the cover layers in particular are highly resistant to separation. |
