Acoustic components and arrangements for helmets

Abstract

A baffle comprising an outer edge defining its perimeter and a loudspeaker receiving region within the perimeter. The loudspeaker receiving region comprises at least one opening between an interior facing side and an exterior facing side of the baffle. A plurality of surface sections on the exterior facing side of the baffle are arranged to provide free intermediate space between the baffle and a surface to which it is mounted, e.g., a protective layer within a helmet. The free intermediate space forms at least one rear sound propagation path from at least one close position near to the loudspeaker receiving region to at least one remote position near to the perimeter of the baffle when a loudspeaker is positioned within the loudspeaker receiving region. The loudspeaker receiving region may be bounded by an inner edge or rim of the baffle, which provides press-fit acoustic sealing against the loudspeaker.
