Abstract

A mounting system is provided to allow the attachment of an acoustic collector to a handheld electronic device such that sound is conducted directly to the device'"'"'s microphone. A fitted case or band encloses part of the device and includes a tube running from the collector to the device'"'"'s microphone. In certain embodiments, the tube may be embedded in the case, and a detachable mount may be provided to connect the collector to the case. The collector may be a stethoscope chestpiece, or an open air collector, such as a parabolic collector.

Claims

1. A stethoscope for use with a microphone-equipped handheld electronic device, said stethoscope comprising:

(a) a detachable fitted casing for attaching to at least a portion of said handheld electronic device, said casing having a broad surface;

(b) a stethoscope chestpiece incorporated with said casing and located on said broad surface of said casing;

(c) a tube configured to carry sound waves through air from said stethoscope chestpiece to a microphone on said handheld electronic device, wherein the entire length of said tube is physically incorporated as a channel within said casing; and

(d) wherein said tube has a microphone end opening configured to be located over the microphone of said handheld electronic device.

2. The stethoscope of claim 1, wherein said handheld electronic device is a Smartphone/Tablet and said casing is designed to hook onto said handheld electronic device.

3. The stethoscope of claim 1, wherein said stethoscope chestpiece has a rim capable of detachably mounting a diaphragm.

4. The stethoscope of claim 1, wherein the stethoscope chestpiece is formed from a flexible rubber material configured to deform to match contours of a surface being listened to.

5. The stethoscope of claim 1, wherein said microphone end opening has a compressible sealing ring configured to be compressed around said microphone, and wherein said casing is configured to compress said sealing ring around said microphone when said casing is attached to said handheld electronic device.

6. The stethoscope of claim 1, wherein said stethoscope chestpiece has a substantially circular sloped inner wall terminating at a hole that corresponds with one end of said tube.

7. The stethoscope of claim 1, wherein said stethoscope chestpiece is formed together with said casing as result of a manufacturing method selected from the group consisting of (A) casting said stethoscope chestpiece and said casing together in the same mold, and (B) three-dimensionally printing said stethoscope chestpiece and said casing together as a single unit.

8. A method for using a stethoscope, said method comprising:

(a) providing a microphone-equipped handheld electronic device;

(b) providing a detachable fitted casing for attaching to at least a portion of said handheld electronic device, said casing having a broad surface;

(c) providing a stethoscope chestpiece as incorporated with said casing and located on said broad surface of said casing;

(d) providing a tube configured to carry sound waves through air from said stethoscope chestpiece to a microphone on said handheld electronic device, wherein the entire length of said tube is physically incorporated as a channel within said casing; and

wherein said tube has a microphone end opening configured to be located over the microphone of said handheld electronic device;

(e) attaching said casing to said handheld electronic device;

(f) contacting said stethoscope chestpiece to an object; and

(g) allowing said handheld electronic device'"'"'s microphone to detect sounds transmitted through said stethoscope chestpiece from said object.

9. The method of claim 8, further comprising providing said handheld electronic device as a Smartphone/Tablet and providing said casing with lips for hooking onto said handheld electronic device.

10. The method of claim 8, further comprising providing a software program capable of augmenting user-selected sound frequencies.

11. The method of claim 8, further comprising providing said handheld electronic device as equipped with a camera, and including using said camera to capture a visual image of the object that is emitting said sounds.

12. The method of claim 8, wherein said microphone end opening is provided as having a compressible sealing ring configured to be compressed around said microphone;

and wherein said casing is configured to compress said sealing ring around said microphone when said casing is attached to said handheld electronic device; and

further comprising the additional step of allowing said sealing ring to be compressed around said microphone when said casing is attached to said handheld electronic device.

13. The method of claim 8, further comprising providing said stethoscope chestpiece as having a circular sloped inner wall terminating at a hole that corresponds with one end of said tube.

14. The method of claim 8, wherein said stethoscope chestpiece is formed together with said casing as result of having been manufactured by a method selected from the group consisting of (A) casting said stethoscope chestpiece and said casing together in the same mold, and (B) three-dimensionally printing said stethoscope chestpiece and said casing together as a single unit.
