A membrane (2) for a microphone (1) is disclosed which comprises a first portion (A1), a second portion (A2), and elements (El..E4, E1'..E4'), which connect said first (A1) and said second portion (A2). The second portion (A2) is arranged for a movement in relation to said first portion (A1) 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 (E1..E4, E1'..E4') 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 (A2). |
