Abstract

An arrangement (1) of an electroacoustic actuator (2) on a vehicle structure (3) of a motor vehicle, has a housing (4), in which at least one loudspeaker (7) is arranged, which separates a front volume (8) from a rear volume (9) in the housing (4). The actuator (2) has a sound emission pipe (5), which projects outwards from the housing (4) and which is fluidically coupled with the front volume (8). A reduced introduction of noise into the vehicle arises when the actuator (2) is held on the vehicle structure (3) with a plurality of holding devices (19), which are arranged on the housing (4) in a circumferential direction (20) of the housing (4) spaced apart from one another. Each holding device (19) is designed as springy in a holding direction (21) and as rigid transversely thereto.
