Systems and methods for a hybrid analog-digital stethoscope

An electronic stethoscope device, comprising:

• a chestpiece including a diaphragm;
• one or more electronic components housed within the chestpiece, wherein the one or more electronic components comprise a microphone and a speaker, the speaker and the microphone positioned on a same wall of the chestpiece;
• an output tube coupled to the chestpiece via a connector, wherein the connector includes an acoustic pathway therein that includes a first section in acoustic communication with the output tube and a second section in acoustic communication with one of the speaker and the diaphragm depending on a selected mode of the electronic stethoscope device, wherein:
• in digital mode, the acoustic pathway is in acoustic communication with the speaker;
• and
• in analog mode, the acoustic pathway is in acoustic communication with the diaphragm.

A method of operation of a hybrid analog-digital stethoscope, comprising:

• receiving user input selecting one of a digital mode and an analog mode;
• in response to selection of the digital mode:
• receiving auscultated sound with a microphone detected via a diaphragm of a chestpiece, the chestpiece including a sound collecting interface, a first acoustic channel, a second acoustic channel, the microphone, and a speaker;
• converting the auscultated sound to an electronic signal with the microphone;
• modifying the electronic signal with an electronic acoustic modifier;
• and
• outputting the electronic signal via the speaker to an output tube via the first acoustic channel within a connector configured to acoustically connect the chestpiece to the output tube, wherein the first acoustic channel is in acoustic communication with the speaker in the digital mode while the output tube is sealed off from the second acoustic channel;
• and
• in response to selection of the analog mode:
• detecting auscultated sound with the diaphragm;
• and
• outputting the auscultated sound to the output tube via the second acoustic channel within the connector, wherein the second acoustic channel is in acoustic communication with the diaphragm in the analog mode while the output tube is sealed off from the first acoustic channel, wherein the first acoustic channel is acoustically isolated from the second acoustic channel, wherein the user input comprises rotation of the connector with respect to the chestpiece, and wherein the microphone and the speaker are housed within the chestpiece and positioned on a same wall of the chestpiece.
