  • Piezoelectric biological sound monitor with printed circuit board
    Patent number: 6661161
    Abstract: The piezoelectric sound monitor comprises a piezoelectric membrane including an inner face, an outer face, and first and second peripheral portions. The piezoelectric sound monitor further comprises a piezoelectric membrane support structure including an outer face, two first mutually facing membrane-clamping walls, a first electrically conductive area, two second mutually facing membrane-clamping walls, and a second electrically conductive area. The inner face of the piezoelectric membrane is applied to the outer face of the support structure. The first peripheral portion of the piezoelectric membrane is clamped between the two first walls, and the first electrically conductive area is located on one of the two first walls for electrically contacting the inner face of the piezoelectric membrane.
