Latest Patents

Imanishi's latest patents include a sound reproduction device, sound reproduction method, and sound reproduction program. This innovative sound reproduction device is designed for use in acoustic spaces, such as passenger compartments. It effectively controls the levels of reproduced sounds at two evaluation points set at the seats within the compartment. Specifically, the device manages the phase of the sound signal inputted from external sources and supplies the sound signals to a pair of speakers. The phase control is executed for multiple listening positions, ensuring that the sum of reproduced sound levels at the two evaluation points exceeds the sum obtained when the sound signal is reproduced from only one speaker.

Another significant patent is the surround signal generating device, which includes a surround signal generating unit. This unit subtracts a sound signal obtained by multiplying a first gain by an inputted sound signal of the right channel from the inputted sound signal of the left channel to generate a surround signal for the left channel. Similarly, it generates a surround signal for the right channel by subtracting a sound signal obtained by multiplying a second gain by the inputted sound signal of the left channel from the inputted sound signal of the right channel. The gain setting unit adjusts the first and second gains to ensure a correlation between the generated surround signals and the actual content's surround sound.
