A membrane ( 2 ) for an electroacoustic transducer ( 1 ) is disclosed, wherein a thickness (d) of said membrane ( 2 ) and an average Young's modulus (Eavg) of said membrane ( 2 ) are chosen in such a way that the critical load (Fbc), which causes the membrane ( 2 ) to buckle and/or crinkle, is increased compared to a reference membrane. The reference membrane made of Polycarbonate has the same shape, dimension, and stiffness in its direction of movement (MOV) as said membrane ( 2 ). According to the result of investigations on buckling and/or crinkling, said effect occurs with different critical buckling/crinkling loads for membranes of the same shape and dimension, but made of different materials, even when the stiffness of the membranes in their direction of movement-and hence their resonant frequency-is identical.
