PIEZOELECTRIC BIOLOGICAL SOUNDS MONITOR

摘要

The biological sounds monitor (100) comprises a piezoelectric membrane (105) and a mechanical assembly. The latter mechanical assembly includes a membrane support (101) on which the piezoelectric membrane is mounted, and a wave-propagating mechanism (108) disposed on one side of the piezoelectric membrane. Upon use of the biological sound monitor, the wave-propagating mechanism is interposed between the piezoelectric membrane and an examinee's body to propagate acoustic waves from the examinee's body to the piezoelectric membrane. Advantageously, the membrane support comprises a piezoelectric membrane tensioning mechanism.
