Latest Patents
Hamada's latest patents include a disc player and a fluid flow control speaker system. The disc player is an apparatus designed to reproduce information signals recorded in spiral or coaxial tracks of a record disc. It features a pick-up device that scans the track while the disc rotates, a driver for rotating the disc, and a tracking device that controls the tracing of the tracks. Additionally, it includes a transporting device that moves the pick-up device radially and a controller that allows the pick-up device to intermittently trace nonadjacent groups of tracks. This innovative design enhances the playback experience by reproducing information signals from various tracks.
The fluid flow control speaker system consists of a fluid source and multiple flow pipes connected to it. Each pipe has an opening corresponding to the bit orders of a Pulse Code Modulated (PCM) input signal. The system controls the fluid flow through each pipe based on the PCM signal, producing an analog flow output signal without converting the PCM signal to an analog format. This technology represents a significant advancement in audio signal processing.
