Latest Patents

Daisuke Aoki holds a patent for a drive control circuit for vibration speakers. This invention involves a drive signal generating unit that produces a cyclic waveform containing a zero period in a vibration mode. The driver unit generates drive current in response to this signal, supplying it to a voice coil. An induced voltage detector identifies the induced voltage occurring in the voice coil during a nonconducting period. Additionally, a zero-cross detector detects the zero cross of the induced voltage. The drive signal generating unit estimates the eigen-frequency of the vibration speaker from the detected zero cross position, adjusting the frequency of the drive signal accordingly.
