Abstract
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.
