Abstract

A microphone having a housing that includes a bottom part and an upper part, and a transducer element arranged in the housing and which is electrically and mechanically connected to the bottom part. For stress-free mounting of the transducer element, a flexible connecting element is proposed, which is pliable and/or compressible, is arranged between the transducer element and the upper part, and connects the transducer element to the upper part. The connecting element includes a plastic, in which gas bubbles are distributed, the gas bubbles having a volume fraction of between 50 and 98% in the connecting element.
