摘要

The instrument has a housing (1), which exhibits a hollow chamber (4) for receiving loud speakers (9, 10). The housing encompasses sound channels (5, 6) that are diverted from the hollow chamber. The hollow chamber and the sound channels are integrated in the housing. The sound channels are designed at a bottom side of the housing. Ends (8) of the sound channels turned away from the hollow chamber are oriented in direction of an inner space of a vehicle. The sound channels are curved, and exhibit a horn structure. The housing is made of plastic as an injection molding part.
