Abstract
An audio signal output system including a first audio signal path, a second audio signal path and control electronics that provide a mixed sound from sound sources to the first and second audio signal paths, and control the mixed sound in accordance with a position at which a sound image associated with at least one of the sound sources is localized relative to an orientation of a user's head. The control electronics provide one or more signals corresponding to the mixed sound to the first and second audio signal paths based on one or more transfer functions associated with one or more values corresponding to at least one of a distance from the user to the at least one sound source, an angle of the user with respect to the at least one sound source, and a size of a space in which the user is located.
Claims19
An audio signal output system comprising:
- a first audio signal path;
- a second audio signal path;
- and
- control electronics that provide a mixed sound from a plurality of sound sources to the first audio signal path and the second audio signal path, and control the mixed sound on the first audio signal path and the second audio signal path in accordance with a position at which a sound image associated with at least one of the sound sources is localized relative to an orientation of a user's head,
- wherein the control electronics is configured to provide one or more signals corresponding to the mixed sound to the first audio signal path and to the second audio signal path based on one or more transfer functions associated with one or more values corresponding to at least one of a distance X from the user to the at least one sound source, an angle Y of the user with respect to the at least one sound source, and a size Z of a space in which the user is located.
A method of providing an audio output device, the method comprising:
- providing control electronics having a first signal output path and a second signal output path;
- configuring the control electronics to provide a mixed sound from a plurality of sound sources to the first signal output path and to the second signal output path;
- configuring the control electronics to control a position at which a sound image associated with at least one of the sound sources is localized in accordance with an orientation of a user's head;
- control electronics that provide a mixed sound from a plurality of sound sources to the right ear piece and the left ear piece, and control a position at which a sound image associated with at least one of the sound sources is localized in accordance with an orientation of the user's head when the device is worn by the user;
- and
- configuring the control electronics to provide one or more signals corresponding to the mixed sound to the first signal output path and to the second signal output path based on one or more transfer functions associated with one or more values corresponding to at least one of a distance X from the user to the at least one sound source, an angle Y of the user with respect to the at least one sound source, and a size Z of a space in which the user is located.
