Sound transmission arrangement for motor vehicle has device for altering static pressure in intermediate space between first, second membrane elements between sound input, output stages

摘要

The arrangement has a sound entry section (1) for detecting a stimulating sound event, a sound output section (2) for outputting an output sound event and a membrane device (3) for separating the entry section from the output section. The membrane device has first and second membrane elements (4,6) at a distance apart forming an intermediate space (5) and a pressure change device (7) for altering the static pressure in the space.
