Described herein are a protective element configured to be connected to an electroacoustic transducer or a sound tube included in a hearing device, the protective element comprising a 3D-shaped membrane enclosing a cavity with an opening at which the membrane is configured to connect to the transducer or sound tube, wherein the membrane has one or more thinner portions configured to transmit sound and one or more thicker portions at which a rigidity of the membrane is greater than at the thinner portions.

Protective element for an electroacoustic transducer of a hearing device or for a sound tube included in a hearing device

Described herein are a protective element configured to be connected to an electroacoustic transducer or a sound tube included in a hearing device, the protective element comprising a 3D-shaped membrane that has two or more first portions having a first thickness that are configured to transmit sound and two or more second portions having a second thickness. The first thickness is less than the second thickness such that a rigidity of the 3D-shaped membrane is greater at the two or more second portions than at the two or more first portions. At least two of the two or more second portions are spaced from one another along a circumference of the 3D-shaped membrane by at least one of the two or more first portions.
