Abstract: A sound system comprises at least three audio driver arrangements (101, 103, 105) for emitting audio signals. The audio driver arrangements (101, 103, 105) are angled relative to each other to emit sound signals in different directions angled at least 45° apart. A driving unit (201, 203, 205) is provided for each audio driver arrangement (101, 103, 105) to generate a drive signal. The audio driver arrangements (103, 105) angled most relative to each other are arranged to emit audio signals being between 90° and 270° out of phase. The driving arrangement (201) for the third audio driver arrangement (101) has a varying phase response with a variation resulting in the emitted audio signal varying between a first phase interval proximal the signal emitted from a first of the other audio driver arrangements (103) and a second phase interval proximal to the signal emitted from the second of the other audio driver arrangements (105). The invention may e.g.

Abstract: A device (100) for generating a vibration source driving signal (DS) is described, which device (100) comprises an input (101) for receiving an input signal (IS) and an output (102) for providing said driving signal (DS), generating means (103; 803) for generating a control signal (CS) which is representative of dynamic signal changes of the input signal (IS), and a processing unit (105; 201; 301; 401; 804) adapted to process a source signal (SRS; IAS) based on the control signal (CS) yielding said driving signal (DS).

Abstract: A device (100) for processing audio data (101), wherein the device (100) comprises an uplifting means (102) adapted for uplifting a low-frequency component of the audio data (101), and an adjustment means (109) adapted for selectively adjusting an attenuation of the low-frequency component of the audio data (101).

Abstract: The invention relates to an apparatus (1) for amplifying bass frequencies of an audio signal (AL, AR). The bass components are applied to a controllable amplifier (17).
