Abstract
An earphone has a membrane mounted on a membrane carrier and arranged between a top space and a bottom space; a membrane actuator implemented to deflect the membrane in dependence on a control signal; a housing where the membrane carrier, the membrane and the membrane actuator are arranged, wherein the housing has a sound exit, wherein the membrane carrier has openings, and wherein the membrane has holes, and wherein the openings and the holes connect the top space and the bottom space to each another, such that gas can move through the openings and holes between the top space and the bottom space.

An earphone comprising:
- a membrane mounted on a membrane carrier and arranged between a top space and a bottom space;
- a membrane actuator implemented to deflect the membrane in dependence on a control signal;
- a housing where the membrane carrier, the membrane and the membrane actuator are arranged, wherein the housing comprises a sound exit,
- wherein the membrane carrier comprises openings, and wherein the membrane comprises holes,
- wherein the openings and the holes connect the top space and the bottom space to each other, such that gas can move through the openings and holes between the top space and the bottom space.
A method for producing an earphone, comprising:
- providing a membrane with holes and a membrane carrier with openings;
- placing the membrane, the membrane carrier and the membrane actuator, which is implemented to deflect the membrane in dependence on a control signal, in a housing comprising a sound exit, such that the openings and holes connect a top space above the membrane and a bottom space below the membrane to each other, such that gas can move through the openings and holes between the top space and the bottom space.
The method according to claim, further comprising:
- arranging a further membrane, which is arranged at a further membrane carrier, in the housing, wherein the further membrane comprises fewer holes than the membrane or no holes, and can be actuated by a further membrane actuator, wherein the further membrane carrier comprises fewer openings than the membrane carrier or no openings.
