Title:
SOUND/VIBRATION CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/181955
Kind Code:
A1
Abstract:
This sound/vibration conversion apparatus is provided with: a vibration device; a sound capturing unit which captures a sound signal; a spectrum computation unit which performs a spectrum computation on the basis of the sound signal captured by the sound capturing unit; a vibration constitution unit which performs constitution of tactile vibration on the basis of at least a part of the computation result obtained by the spectrum computation unit; and a vibration device driving unit which drives the vibration device on the basis of the result of vibration constitution performed by the vibration constitution unit, wherein the spectrum computation unit has a plurality of computation processing units, the time required for capturing the sound signal is different for each computation processing unit, and the vibration constitution unit performs constitution of tactile vibrations such that the shorter the sound capturing time of the computation processing unit is, the higher the frequency, in the spectrum computation result thereof, to be used for constitution of tactile vibrations is.
