Title:
VIBROACOUSTIC APPARATUS, VIBROACOUSTIC OUTPUT METHOD AND VIBROACOUSTIC PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/151636
Kind Code:
A1
Abstract:
The objective of the invention is to convey acoustic signals, outputted from a sound source, to a listener as vibrations, while achieving signal output level reduction and power saving. A vibroacoustic apparatus comprises: an envelope detection unit (204) that detects the envelope signals of acoustic signals outputted from a sound source; a vibration conveyance member that can cause a listener to experience the vibration of a low frequency sound outputted from a low frequency output speaker that outputs acoustic signals; and a frequency conversion unit (205) that multiplies the envelope signals by sinusoidal waves having the same frequency as a resonance frequency obtained from an impulse response of the low frequency output speaker provided in the vibration conveyance member, thereby generating the acoustic signals in which frequency conversions based on the resonance frequency have been performed. The acoustic signals, which have been subjected to the frequency conversions in the frequency conversion unit (205), are outputted from the low frequency output speaker.
