Abstract
A micro-microphone, for attachment to the clothing or directly to the body of a user, has a housing with a housing mantle, an end plate connected to a first end of the housing mantle, and a bottom plate connected to the second end of the housing mantle. The housing mantle has one or more openings, each covered by a membrane positioned external to the housing mantle. The housing and the membranes thus define an inner hollow space inside the housing. A flaccid diaphragm is connected externally to a portion of the housing and encloses together with the portion of the housing a compensation chamber. The flaccid diaphragm seals the compensation chamber moisture-tightly. A component of high acoustic impedance connects the inner hollow space inside the housing to the compensation chamber. Pressure compensation is thus realized while moisture is excluded from the interior of the microphone.
