Abstract: The present disclosure relates to a device for wireless charging of an electrical energy store of a mobile terminal for a motor vehicle, the device including charging electronics positioned within a housing. The housing includes a support region on which to place the mobile terminal, the support region including at least two elevations, each elevation has a first predetermined height extends along a length of the support region, and is arranged in parallel at a predetermined distance from one another. When the mobile terminal is placed on the at least two elevations, an air channel is formed. The housing includes at least one air inlet opening and at least one air outlet opening configured to blow air out into the air channel. Furthermore, at least one barrier that swirls the air blown out into the air channel is arranged in the air channel.

Abstract: The disclosure relates to a multi-layered speaker cover for covering a speaker. The speaker cover has at least one first layer and a second layer, wherein the first layer is an air-permeable layer and the second layer is a layer with through-holes for reducing dynamic pressure.

Abstract: The approach relates to an energy absorption element for a support frame of a motor vehicle and is characterized in that a cross-sectional profile is designed as a hollow profile which remains constant along a longitudinal direction of the energy absorption element having at least two closed chambers, so that the energy absorption element comprises at least two mutually separate chamber cavities and the at least two chamber cavities have an elongated shape along the longitudinal direction of the energy absorption element and each chamber cavity is open at two longitudinal ends of the energy absorption element and each chamber cavity is fluidly connected to a sound generator.
