Title:
THREE-DIMENSIONAL SELF-SOUNDING CANONICAL COMPLEX SPATIAL AUDIO DEVICE THAT REPRODUCES SELF-SOUNDING SOUND ACCORDING TO ITS PHYSICAL ESSENCE
Document Type and Number:
Japanese Patent JP2023060993
Kind Code:
A
Abstract:
To provide an audio technology that restores the sound quality, timbre, and sense of space of the original sound according to the various self-resonant sounds that the original sound contains on the basis of the inventor's discovery that the sound quality, timbre, and sense of space of the original sound, which a conventional loudspeaker unit has not physically restore are due to the loss of phase-shifted self-sounding sound.SOLUTION: Three-dimensional acoustic canonicalization conditions (multiple) are applied to a three-dimensional vibrating structure consisting of six square solid flat plates arranged in a cubic shape, which emits two-dimensional self-resonant sound by vibrating vertically and horizontally according to the excitation frequency, and then the three-dimensional vibration structure is made into a three-dimensional self-acoustic canonical vibration structure, and the sound quality, timbre, and the sense of space of the original sound are restored according to the various self-sounding sounds contained in the original sound signal.SELECTED DRAWING: Figure 1
