摘要： A speaker system comprises a first speaker (203) and a second speaker (205). A driving circuit receives an audio signal and comprises a first drive circuit (209) generating a first drive signal for the first speaker (203) in response to a first filtering of the audio signal with a first pass band. A second drive circuit (211) generates a second drive signal for the second speaker (205) in response to a second filtering having a second pass band which comprises a frequency band below the first pass band. A delay (213) delays the second drive signal relative to the first drive signal. The sound from the second speaker is directionally radiated with a directional radiation pattern having a notch towards the listening position (111). The system uses the precedence effect and non-direct low frequency audio radiation to ensure that directional cues are predominantly provided by the first speaker (203) which may be small and positioned remote from the second speaker (205).

摘要： A sound reproduction system for reproducing an audio signal as originating from a first direction relative to a nominal position (211) and orientation of a listener is provided. The system comprises a first sound transducer arrangement (105) arranged to generate sound reaching the nominal position (211) from a first position corresponding to the first direction; and a second sound transducer arrangement (107) arranged to generate sound reaching the nominal position (211) from a second position corresponding to a different direction than the first direction. The arrangements may specifically be loudspeakers positioned at the given positions. A drive circuit (103) generates a first drive signal for the first sound transducer arrangement (105) and a second drive signal for the second sound transducer arrangement (107) from the audio signal. The first position and the second position are located on a sound cone of confusion for the nominal position (211) and the nominal direction. A more flexible loudspeaker positioning may be achieved.

摘要： A system for determining loudspeaker position estimates comprises motion sensors (201, 203, 205) arranged to determine motion data for a user movable unit where the motion data characterizes movement of the user moveable unit. A user input (207, 209) receives user activations which indicate that at least one of a current position and orientation of the user movable unit is associated with a loudspeaker position when the user activation is received. The user activation may for example result from a user pressing a button. An analyzing processor (211) then generates loudspeaker position estimates in response to the motion data and the user activations. The system may e.g. allow a speaker position estimation to be based on a handheld device, such as a remote control, being pointed towards or positioned on a speaker.

A driving circuit receives an audio signal and comprises a first drive circuit (209) generating a first drive signal for the first speaker (203) in response to a first filtering of the audio signal with a first pass band. A second drive circuit (211) generates a second drive signal for the second speaker (205) in response to a second filtering having a second pass band which comprises a frequency band below the first pass band. A delay (213) delays the second drive signal relative to the first drive signal. The sound from the second speaker is directionally radiated with a directional radiation pattern having a notch towards the listening position (111). The system uses the precedence effect and non-direct low frequency audio radiation to ensure that directional cues are predominantly provided by the first speaker (203) which may be small and positioned remote from the second speaker (205).
