Abstract
An acoustic system includes a supply device, which is connected to a network and configured to supply an acoustic signal to the network and at least one output device configured to output a sound that is based on the acoustic signal supplied from the supply device via the network. The acoustic system also includes a detection unit configured to detect whether the at least one output device is in a state of being capable of outputting the sound and a control device configured to control, based on a result of the detection by the detection unit, to which output device the acoustic signal is to be supplied out of the at least one output device.
Claims20
An acoustic system, comprising:
- a supply device, which is connected to a network and configured to supply an acoustic signal to the network;
- at least one output device configured to output a sound that is based on the acoustic signal supplied from the supply device via the network;
- a detection unit configured to detect whether the at least one output device is in a state of being capable of outputting the sound;
- and
- a control device configured to control, based on a result of the detection by the detection unit, to which output device the acoustic signal is to be supplied out of the at least one output device.
An acoustic system control device, comprising:
- an acoustic signal obtaining unit configured to obtain an acoustic signal;
- an optimum frequency characteristics obtaining unit configured to obtain, from each of a plurality of output devices each configured to output a sound based on the acoustic signal, optimum frequency characteristics of the each of a plurality of output devices;
- an output feasibility information obtaining unit configured to obtain output feasibility information, which indicates whether or not at least one of the plurality of output devices is in a state of being capable of outputting the sound;
- and
- a selection unit configured to select, from among the plurality of output devices, based on the acoustic signal, the optimum frequency characteristics, and the output feasibility information, at least one output device to which the acoustic signal is to be output.
An acoustic system control method, comprising:
- supplying an acoustic signal to the network by a supply device, which is connected to a network;
- outputting a sound that is based on the acoustic signal supplied from the supply device via the network by at least one output device;
- detecting whether the at least one output device is in a state of being capable of outputting the sound by a detection unit;
- and
- controlling, based on a result of the detection by the detection unit, to which output device the acoustic signal is to be supplied out of the at least one output device, by a control device.
