A membrane ( 2 ) for a microphone ( 1 ) is disclosed which comprises a first portion (A 1 ), a second portion (A 2 ), and elements (E 1 . . . E 4 , E 1 ' . . . E 4 '), which connect said first (A 1 ) and said second portion (A 2 ). The second portion (A 2 ) is arranged for a movement in relation to said first portion (A 1 ) around an idle position, which movement includes at least a translatory component in a direction of movement (dm) normal to said membrane ( 2 ). The elements (E 1 . . . E 4 , E 1 ' . . . E 4 ') are provided for definition of a spring constant for said movement around said idle position and are arranged substantially along the outer border of said second portion (A 2 ).
