Universal stethoscope amplifier with graphic equalization and teaching and learning ports

摘要

The present invention is directed to an assembly used for modifying an ordinary acoustic stethoscope to an electronically amplified stethoscope. This assembly is mechanically married to a conventional stethoscope's tubular structure. An earpiece unit which replaces the standard earpiece on the earpiece-end of the ordinary acoustic stethoscope, is positioned so the standard air column response of any ordinary acoustic stethoscope is picked up by a microphone placed inside this special earpiece unit, thus capturing the acoustic output of the parent stethoscope and transmitting it back to a preamplifier/amplifier and frequency equalizer unit (graphic equalizer). The electronic signal is then directed to a speaker located in the special earpiece unit for monitoring by the operator, or alternatively, such signal is directed to a number of other remote units for the purpose of facilitating teaching and learning.
