Abstract
A multi-mode sound reproduction device is disclosed including a direct radiation sound device, a diffuse radiation sound device and a selection device in signal communication with both the direct radiation sound device and diffuse radiation sound device, the selection device capable of selecting between the direct radiation sound device for one mode of operation and the diffusion radiation sound device for another mode of operation in response to a received control signal.
Claims30
A multi-mode sound reproduction system (MSRS) comprising:
- a direct radiation device and a sound array that produces a diffuse sound radiation and that is distinct from the direct radiation device, the direct radiation device and sound array arranged in a MSRS assembly operating as a single location sound source in a sound environment;
- and
- a selection device in signal communication with both the direct radiation device and sound array, the selection device being capable of selecting between the direct radiation device for a direct mode of operation and the combination of the sound array and direct radiation device for a diffuse mode of operation in response to a received control signal.
A method for producing multi-mode sound from a single sound source location in a sound environment, the method comprising:
- receiving a control signal;
- and
- determining the mode of operation of a loudspeaker having a direct radiation device for a direct mode of operation and a sound array that produces a diffuse sound radiation for a diffuse mode of operation, the sound array being distinct from the direct radiation device, where the mode of operation corresponds to the control signal.
A multi-mode sound system from a single sound source location in a sound environment, the system comprising:
- means for receiving a control signal;
- and
- means for determining the mode of operation of a loudspeaker having a direct radiation
- device for a direct mode of operation and a sound array that produces a diffuse sound radiation for a diffuse mode of operation, the sound array being distinct from the direct radiation device, where the mode of operation corresponds to the control signal.
A signal-bearing medium having software for producing multi-mode sound, the signal-bearing medium comprising:
- logic for receiving a control signal;
- and
- logic for determining the mode of operation of a loudspeaker having a direct radiation device for a direct mode of operation and a sound array that produces a diffuse sound radiation for a diffuse mode of operation, the sound array being distinct from the direct radiation device, the mode of operation corresponding to the control signal.
