Abstract
A microphone assembly comprising a housing in which a transducer element is positioned. In the housing, an upper and a lower chamber are defined, the lower chamber extending at least at one edge of the transducer element and potentially to an upper side thereof. An element, such as a horse-shoe shaped element or a circular element, is provided for separating the upper side of the transducer element into the upper and lower chambers. The transducer element is fixed using flexible fixing means, and space is provided at one or more sides of the transducer element to take up thermal expansion and retraction of the housing and the transducer element.
