WIPO Patent Application WO/2019/071050
Kind Code:
A metallic diaphragm disk (22, 266, 266', 266'') incorporating a piezoelectric material (24, 24', 24.1, 24.2, 24', 24'') bonded thereto and operatively coupled to a base rim (14, 62, 262) of a housing (18, 18', 66, 256) provides for closing an open-ended cavity (20, 20', 270) at the first end (18.1, 18.1') of the housing (18, 18', 66, 256). In one aspect (10', 10'', 10''a, 10''b, 10'''), plastic film (46) adhesively bonded (48, 52) to at least one of an outer rim (47) of the housing (18, 18', 66) or an outer-facing surface (22.2) of the disk (22) provides for receiving an adhesive acoustic interface material (55, 56) to provide for coupling the sound-or-vibration sensor (10', 10'', 10''a, 10''b, 10''') to the skin (36) of a test subject (34). In another aspect (10'''', 10a'''', 10b'''', 10c''''), an outer-facing surface (258.1) of a base portion (258) of the housing (256) provides for receiving an adhesive acoustic interface material (55, 56) to provide for coupling the housing (256) to the skin (36) of a test subject (34), at least one inertial mass (272.1, 272.2) is operatively coupled to a central portion (26, 26.1, 26.2) of the metallic diaphragm disk (266, 266', 266''), and the opening in the first end of the housing (256) is closed with a cover (280).
