Latest Patents

Ozaki's latest patents include a sound processing device, a sound control device, and a sound control method. The sound processing device features an amplifier, a current detector, and a controller. The amplifier amplifies a sound signal to drive a loudspeaker, while the current detector measures the electric current flowing into the amplifier. The controller determines whether to supply power to the amplifier based on a predicted current value and the current detected by the current detector. This predicted current value is calculated according to the volume setting and the level of the sound signal.

Another notable patent is the amplifier apparatus, which introduces a technique for reducing noise superimposed on an output signal. This is achieved while maintaining constant loop gain without increasing the circuit scale or altering the amplifier's transfer function. The technique includes a power-supply voltage control unit that detects the amplitude level of an input audio signal and outputs power with a voltage value indicated by target set voltage value information. Additionally, a PWM modulation unit is employed to correct the pulse width of a PWM signal, ensuring that the amplification gain remains stable.
