Claims

[Scope of utility model registration request]

A main transmission system having a signal input end, a main volume control section, and a main tone control device, and a branch signal from a section of the main transmission system that is downstream of the main volume control section and before the main tone control section is transmitted. A sound field control device comprising a sub-transmission system, and the sub-transmission system is configured to be controllable so that at least one of the volume, delay amount, spread, and frequency characteristics of a branch signal is made different from that of the main transmission system.
