Title:
ACOUSTIC AND VIBRATION INFORMATION ACCUMULATION MECHANISM, ACOUSTIC AND VIBRATION SENSING SYSTEM, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/083846
Kind Code:
A1
Abstract:
 The present invention can more accurately detect bioacoustic signals and biological signals. An acoustic and vibration information accumulation mechanism (10) is configured to have a first layer (11), a second layer (12) and a third layer (13). A natural oscillator (122) having a prescribed natural oscillation frequency is arranged in the second layer (12). When acoustic and vibration information from the trunk and back is input, the natural oscillator (122) vibrates at the natural oscillation frequency, and said vibration as well as the acoustic and vibration information from the trunk and back are combined and emphasized. The combined resonance carrier (RC) contains the emphasized acoustic and vibration information from the trunk and back and can be captured as a clear signal. If a biological signal having a number of Hz equal to or below an aortic pulse wave (APW) or a pulse is obtained from the resonance carrier, the gain of said biological signal is increased, and the biological signal can be more accurately extracted.
