Document Type and Number:
WIPO Patent Application WO/2024/090656
Kind Code:
A1
Abstract:
The present application relates to an abnormal signal detection device using a dual acoustic wave sensor. The abnormal signal detection device using a dual acoustic wave sensor comprises: a housing including a first acoustic wave transmission portion and a second acoustic wave transmission portion; a base substrate located inside the housing and including a first surface and a second surface; a first acoustic wave sensor mounted on the first surface and converting an acoustic wave in a first band into a first electrical signal; a second acoustic wave sensor mounted on the second surface and converting an acoustic wave in a second band into a second electrical signal, wherein the second band includes an overlapping band that at least partially overlaps the first band, and has an intermediate frequency band corresponding to a frequency band lower than an intermediate frequency band of the first band; a signal combining unit which generates a combined signal in which the first electrical signal and the second electrical signal are combined; and a determination unit that determines whether there is an abnormality.
