Abstract: The present invention relates to a user device: a processor (20) configured to process an audio signal to derive a first driving signal and a second driving signal, such that the first driving signal comprises only components of the audio signal having frequencies higher than a threshold frequency and such that the second driving signal comprises components of the audio signal having frequencies above and below the threshold frequency; wherein the processor is configured to simultaneously provide the first driving signal and the second driving signal; a first speaker (30), being configured to generate sound based on the first driving signal; and a second speaker (40), being configured to generate sound based on the second driving signal. Furthermore, the present invention also relates to a corresponding method, a computer program, and a computer program product.
