Abstract: A method for actuating an electric motor with a motor control signal with an application-specific frequency, which signal is provided by an electronic motor control unit, wherein the electric motor is used in a vehicle roof for activating a component of this roof while being connected to a region of the roof. Embodiments provide that the electric motor can be actuated by the motor control unit with an additional signal whose frequency and amplitude are suitable for causing the region of the vehicle roof to which said electric motor is connected to oscillate in order to generate sound.
