US Patent 11356778 Speaker controller, signal supplying device, and speaker system
Article
A speaker controller includes a switch that is inserted on a speaker wiring for supplying a sound signal to a speaker. A switch control circuit can extract and hold an ON/OFF control signal for instructing ON/OFF of the switch from an alternating-current signal supplied via the speaker wiring. A switch control circuit controls ON/OFF of the switch based on the ON/OFF control signal. A power supply circuit can generate a power supply voltage for operating the switch control circuit from the alternating-current signal supplied via the speaker wiring.
