摘要： 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.
