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 based on the acoustic signal supplied from the supply device via the network. Also, the acoustic system includes a control unit, which is provided to the at least one output device on a one-to-one basis, and configured to control necessity/non-necessity of outputting the acoustic signal to an associated one of the at least one output device, based on frequency characteristics of the acoustic signal.
Claims16
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 based on the acoustic signal supplied from the supply device via the network;
- and
- a control unit, which is provided to the at least one output device on a one-to-one basis, and configured to control necessity/non-necessity of outputting the acoustic signal to an associated one of the at least one output device, based on frequency characteristics of the acoustic signal.
An output device, which is one of a plurality of output devices, comprising:
- an acoustic signal obtaining unit configured to obtain an acoustic signal;
- an optimum frequency characteristics obtaining unit configured to obtain, from each of the plurality of output devices each configured to output a sound based on the acoustic signal, optimum frequency characteristics of the each of the plurality of output devices;
- and
- a selection unit configured to select, from among the plurality of output devices, based on the acoustic signal and on the optimum frequency characteristics of each of the plurality of output devices, at least one output device to which the acoustic signal is to be output.
An acoustic system controlling method, comprising:
- supplying an acoustic signal to a network by a supply device which is connected to the network;
- outputting a sound based on the acoustic signal supplied from the supply device via the network by at least one output device;
- and
- controlling necessity/non-necessity of outputting the acoustic signal to an associated one of the at least one output device, based on frequency characteristics of the acoustic signal, by a control unit, which is provided to the at least one output device on a one-to-one basis.
