Sound transmission device for motor vehicle has several resonator chambers working in parallel, of which at least two are different from each other in terms of their frequency tuning

摘要

The device has at least one hollow transmission line (12) connected to communicate at its input with the induction tract (1) and connected to at least one resonator chamber (13) that radiates sound into the vehicle interior (21). Several resonator chambers working in parallel are provided, of which at least two are different from each other in terms of their frequency tuning.
