Abstract
An electronic stethoscopic apparatus including: a housing with a main body having a plurality of switches and jacks electrically installed therein; an audio-signal amplifying device incorporating a pre-amplifying circuit, a low pass filter and a volume controller disposed in the main body and electrically coupled with the switches and jacks; a battery supply replaceably provided in the main body and electrically connected to the audio-signal amplifying device; an audio-wave guiding device having transducers disposed therein for converting audio waves into electric signals and positioned on top of the main body and electrically connected to the audio-signal amplifying device; a wireless radio wave transmitting device also disposed in the main body to receive the electric signals and transmit the same as radio signals; an upper cover of the housing device connected to the top end of the main body and to the audio-wave guiding device; and a body contact device communicatively connected to the audio-wave guiding device. The apparatus permits auscultation can be made through an earphone/speaker and/or recorder for accurate diagnosis, the besides, remote auscultation or bedside group teachings can be achieved by turning on the wireless radio wave transmitting device enabling the radio wave signals to be received by those at a remote place.
