  • Patent number: 7172052
    Abstract: A headphone has a headband and two earpieces each connected to the headband so as to be pivotable about at least two pivot axes. The two pivot axes intersect one another at a point of intersection that is positioned on or near a central axis of the earpiece, respectively. Arms connect the earpieces to the headband, wherein the arms define a first one of the two pivot axes, respectively. A second one of the two pivot axes is fixedly arranged on the headband, respectively. In this way, the earpieces are rotatable about the arms and the arms are rotatable relative to the headband about the second pivot axes.

  • Patent number: 6351543
    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.
