Abstract
A speaker device comprises a housing having an acoustic aperture, a transducer element in the housing configured to receive a first actuation signal and to generate an acoustic output signal. The speaker device comprises a shutter element in the housing configured to receive a second actuation signal and arranged laterally offset to the transducer in the housing. The shutter element is arranged in an acoustic path between the transducer element and the acoustic aperture and comprises a shutter portion movable in opposite directions in response to the second actuation signal. A controller provides the first actuation signal to the transducer element, while the first actuation signal has an ultrasonic signal component modulated with an audio signal component. The controller provides the second actuation signal to the shutter element that has half the frequency of the ultrasonic signal component.
