Abstract
An acoustic bending converter system may have a plurality of bending converters configured such that deformable elements of the bending converters oscillate coplanarly in a common planar layer, wherein the bending converters include different resonance frequencies and different expansions of the deformable elements along a common longitudinal axis which is transversal to a direction of oscillation of the deformable elements. Further, an acoustic apparatus may have such an acoustic bending converter system.
Claims15
An acoustic bending converter system comprising
- a plurality of bending converters configured such that deformable elements of the bending converters oscillate coplanarly in a common planar layer, wherein the bending converters comprise different resonance frequencies and different expansions of the deformable elements along a common longitudinal axis that is transversal to a direction of oscillation of the deformable elements.
An acoustic apparatus comprising
- an acoustic bending converter system comprising at least one bending converter comprising at least one deformable element arranged in a cavity, and
- an opening through which a fluidic volume flow interacting with a movement of the bending converter in the cavity passes and
- a housing adapted to be inserted into an auditory canal, wherein the bending converter system is held in the housing such that the fluidic volume flow is oriented obliquely to a longitudinal axis of the auditory canal and disposed in the auditory canal in a state where the housing is inserted in the auditory canal.
