1. A sound-or-vibration sensor, comprising:
a. a first housing, wherein a first end of said first housing incorporates an open-ended cavity bounded by a base portion and a sidewall, said sidewall is located between said base portion and an opening of said open-ended cavity, a periphery of said opening of an open end of said open-ended cavity abuts an outer rim of said first housing, and said sidewall incorporates a counterbore defining a base rim within said open-ended cavity, wherein said base rim is recessed from said outer rim, and said base rim is proximate to said open end of said open-ended cavity;
b. a metallic diaphragm disk operatively coupled to said base rim of said first housing, thereby providing for closing said open-ended cavity of said first housing;
c. a piezoelectric material bonded to said metallic diaphragm disk on a cavity-facing side thereof;
d. at least one inertial mass either incorporated in, or attached to, said first housing; and
e. a plastic film adhesively bonded to at least one of said outer rim of said first housing or an outer-facing surface of said metallic diaphragm disk, wherein a cavity-facing surface of said plastic film is at least proximally adjacent to said outer-facing surface of said metallic diaphragm disk, and an outer-facing surface of said plastic film provides for receiving an adhesive acoustic interface material to provide for coupling the sound-or-vibration sensor to a skin surface of a test subject.
