Abstract (en)
[origin: EP1341398A1] The device has an audio player, a sound transducer(s) connected to the player via a signal connection and sound transducer orientation data sensors. The player compares current orientation data with reference data to detect a sound transducer orientation change in space. A controler controls a sound output signal filter so a virtual sound source formed by the transducer remains essentially fixed in space if the transducer orientation changes. The device has an audio player, at least one sound transducer connected to the audio player via a signal connection and sensors for detecting orientation data regarding the orientation of the sound transducer in space. The audio player compares current orientation data with reference data to detect a change in orientation of the sound transducer in space and a controler controls a sound output signal filter so a virtual sound source formed by the transducer remains essentially fixed in space when the transducer orientation changes.
