Title: HIGH RESOLUTION STETHOSCOPIC APPARATUS ABSTRACT OF THE DISCLOSURE A stethoscopic apparatus with a plurality of improved chestpieces is disclosed. Each chestpiece in the stethoscopic apparatus of the invention includes a base member and a resonance membrane connected to the base member. The resonance membrane has a plateau-shaped protrusion formed thereon which forms a sealed resonance chamber between the base member and the resonance membrane. The resonance membrane is preferably made of plastic polymers and the periphery of the resonance membrane is thermal set to form a relatively stiff rim for engaging with the base member of the chest member. Since the resonance membrane provides a compulsory resonance chamber during the operation of the stethoscopic apparatus, the resolution ability of the chestpiece is greatly improved.
