Title: Tomohiko Ise: Innovator in Audio Technology
Introduction
Tomohiko Ise is a prominent inventor based in Iwaki, Japan. He has made significant contributions to the field of audio technology, holding a total of 7 patents. His work focuses on enhancing audio systems and sound field control, showcasing his expertise and innovative spirit.
Latest Patents
One of Tomohiko Ise's latest patents involves an advanced audio system. This system features a digital tuner in a broadcasting receiving unit that outputs audio data at a sample rate of Fs+dr (Hz). Additionally, an ASRC rate-converts audio data to a sample rate of Fs+ds (Hz) and transmits the resulting audio data to an audio processing unit. A DAC in the audio processing unit then analog-converts the received audio data at an output rate of Fs+da (Hz) and outputs the resulting audio data to a speaker. The synchronization of the sample rate Fs+ds and the output rate Fs+da is achieved through a SYNC signal transmitted from the broadcasting receiving unit to the audio processing unit on a 125 ms cycle. Furthermore, a relationship of (da−ds)×0.125<1 is assured for the sample rate Fs+ds and the output rate Fs+da.
Another notable patent is for a sound field control apparatus and method for controlling sound field. This apparatus includes at least two main microphones, with each main microphone having a set of at least two sub microphones arranged in different axis directions. A filtering unit and a filter coefficient calculating unit are also included, which calculates a filter coefficient for the filtering unit. This coefficient is used to control sound pressure levels and air particle velocities of an output audio signal based on the sound pressure levels detected by the main and sub microphones.
