ACOUSTIC SENSOR AND STETHOSCOPE

This abstract first appeared for US patent application 19001139 titled 'ACOUSTIC SENSOR AND STETHOSCOPE

Original Abstract Submitted

An acoustic sensor includes a piezoelectric plate including a conductor plate with first and second surfaces, and a piezoelectric element on the second surface, a cover facing the first surface of the conductor plate, a support substrate facing the second surface of the conductor plate and the piezoelectric element, a first connector including a conductor between the piezoelectric element and the support substrate and electrically connecting the piezoelectric element and the support substrate, a first insulating structure including an insulator between the second surface of the conductor plate and the support substrate at an outer edge of the second surface of the conductor plate, and a second connector including a conductor on an outer edge of the first surface of the conductor plate and electrically connecting the conductor plate and the cover.
