Title:
Housing loudspeaker
Abstract:
The invention relates to a housing loudspeaker which in addition to the loudspeaker opening has a further opening in its outer wall of the housing. Components are provided in the inner space between the loudspeaker and the opening which should eliminate the sound emitted into the inside by the loudspeaker. For a surprising effective elimination of the sound and a corresponding capacity increase of the loudspeaker a consistent filling of a cross sectional face in the box intermediary space is provided which is composed of two partial faces with mutual components of different functions. One of the partial faces is designed as a large face and consists of a flow tight finishing of an elastically vibrating braced mass, for which a plate combination is used in particular. The other partial face is designed of a smaller face and consists of a flow opening which, however, is closed with a layer of granulated or transversely directed thread like material.
