Latest Patents

Takizawa holds a patent for an "Automatic Volume Adjusting Apparatus." This invention comprises a volume adjusting device connected between a sound signal source and a loudspeaker. It includes a first rectifier circuit that generates a first signal with a D.C. level corresponding to the sound signal level supplied to the loudspeaker. Additionally, it features a microphone and a second rectifier circuit that generates a second signal reflecting the ambient noise level. A subtraction circuit calculates the level difference between the first and second signals, while a gate circuit samples this difference at predetermined intervals. Finally, an integrator circuit holds the output for a specified time, controlling the volume adjusting device accordingly. This innovative technology enhances the listening experience by automatically adjusting the volume based on ambient noise levels.
