SYSTEMS AND METHODS FOR ELECTRONIC STETHOSCOPE WITH ACTIVE HEADSET
The present description relates generally to methods and systems for an electronic stethoscope device with an active headset, including a speaker to project audio data generated by a chestpiece, the headset defining a closed back volume for the speaker. In this way, the headset provides a back volume of the speakers in order to tune the frequency response of the speakers to a target frequency mimicking the frequency produced by a conventional acoustic stethoscope.
1 . An electronic stethoscope, comprising:
a headset including a speaker to project audio data generated by a chestpiece and signal wires configured to transmit the audio data from the chestpiece to the speaker, the headset defining a closed back volume for the speaker.
2 . The electronic stethoscope of claim 1 , wherein the back volume comprises a tube of the headset with a volume tuned to provide a target frequency response for the speaker.
3 . The electronic stethoscope of claim 2 , wherein the headset comprises an output tube configured to couple to the chestpiece and a first stem and a second stem branching from the output tube, the first stem coupled to a first earpiece housing the speaker, and wherein the tube of the headset is the first stem.
4 . The electronic stethoscope of claim 3 , wherein the first stem includes a cap to seal the back volume from the output tube.
5 . The electronic stethoscope of claim 4 , wherein the cap is positioned within the first stem at a location selected to form the volume.
6 . The electronic stethoscope of claim 3 , wherein the speaker is a first speaker and the closed back volume is a first closed back volume, and wherein the second stem is coupled to a second earpiece housing a second speaker, and wherein the second stem forms a second closed back volume for the second speaker.
7 . The electronic stethoscope of claim 2 , wherein the closed back volume includes a mechanical acoustic modifier.
8 . The electronic stethoscope of claim 7 , wherein the mechanical acoustic modifier comprises acoustic dampening foam.
9 . The electronic stethoscope of claim 2 , wherein target frequency response includes low audio frequencies typically produced by the heart and lungs.
10 . The electronic stethoscope of claim 1 , further comprising a connection mechanism configured to couple headset to the chestpiece, the connection mechanism including a twist-lock mechanism which holds the headset rigidly against the chestpiece and provides electrical contact.
11 . The electronic stethoscope of claim 10 , wherein the connection mechanism is releasable.
12 . The electronic stethoscope of claim 10 , wherein the twist-lock mechanism is configured to lock with less than one full rotation.
13 . The electronic stethoscope of claim 10 , wherein the connection mechanism, when locked, is configured to hold the headset at a fixed orientation relative to the chestpiece.
14 . An electronic stethoscope, comprising:
a chestpiece operable to generate audio data of a patient; and
a headset including an output tube and a first stem and a second stem branching from the output tube, the first stem coupled to a first earpiece including a first speaker, the headset further including signal wires configured to transmit the audio data from the chestpiece to the first speaker, the first speaker including a speaker driver having a backside exposed to a closed back volume formed by the first earpiece and a hollow region within the first stem.
15 . The electronic stethoscope of claim 14 , wherein the hollow region within the first stem that forms the closed back volume terminates at a cap within the first stem, the cap positioned at a location selected to provide a target frequency response for the first speaker.
16 . The electronic stethoscope of claim 14 , wherein the hollow region within the first stem that forms the closed back volume includes a mechanical acoustic modifier.
17 . The electronic stethoscope of claim 14 , wherein the headset includes a connector configured to be housed within a corresponding connector of the chestpiece.
18 . The electronic stethoscope of claim 14 , wherein the second stem is coupled to a second earpiece including a second speaker, the second speaker including a second speaker driver having a backside exposed to a second closed back volume formed by the second earpiece and a second hollow region within the second stem.
