Title: The Innovations of Susumu Seyoshi
Introduction
Susumu Seyoshi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electronics, particularly in the area of loudspeaker technology. His innovative approach has led to the development of a unique muting circuit that enhances the functionality of loudspeakers.
Latest Patents
Seyoshi holds a patent for a muting circuit for loudspeakers. This muting circuit is designed to disconnect a loudspeaker from an amplifier immediately upon the interruption of the power supply. The circuit includes an around-zero-volt detection mechanism that identifies the zero volt level of commercial AC voltage. An RC time constant circuit is controlled by the output of this detection circuit, allowing it to charge or discharge the capacitor only when the around-zero volt level is detected. A threshold circuit is connected to the RC time constant circuit, which operates a loudspeaker relay when the capacitor's charge exceeds or falls below a predetermined level. This innovation is crucial for preventing unwanted noise during power interruptions.
