Abstract: A speaker transducer, comprising a speaker membrane and two drive members connected to an outer membrane circumference of the speaker membrane for driving the speaker membrane. A substantially rigid support member is connected to each of the two drive members and extends there between, wherein the support member is connected to and extends along the speaker membrane.

Abstract: Membrane unit for a speaker device, the membrane unit (1) comprising a membrane (2) and at least two coils (3). The respective longitudinal axes of the at least two coils (3) are arranged in parallel along a main axis (A), a main surface being formed perpendicular to the main axis (A). The at least two coils (3) are positioned adjacent to each other and mechanically connected to the membrane (2), the membrane (2) being substantially flat and having a major surface (S) parallel to the main surface. Wiring (4, 5, 6) to the at least two coils (3) is provided at least partly on a flat part of the membrane (2).
