Abstract: A front-end part (12) for a motor vehicle (10) has an inlet opening (14) for the introduction of headwind. An air duct adjoins the inlet opening (14) for supplying the headwind to a radiator and/or to an air conditioning device. An air-directing element (16) directs the headwind into the air duct. A sound generator (18) outputs an acoustic signal along a sound path. The air-directing element (16) at least partially covers the sound generator (18) in the sound path. The air-direction element (16) has a textile material that is sound-permeable for the acoustic signal of the sound generator. The textile material conducts headwind away and also covers the sound generator (18) without significantly affecting the perception of the acoustic signal. Therefore, a simple design of a front-end part (12) for a motor vehicle (10) is provided with a small number of components.

However, the gap (14) can be closed via a closure device (15). The closure device (15) has a multi-layered, flexible sheetlike structure (16) with at least one front outer, flexible layer (17) and a rear outer, flexible layer (18). In the extended operating position, the front outer layer (17) can be stretched with the aid of a stiff clamping element (19) and the rear outer layer (19) can be stretched with the aid of a flexible clamping element (20).
