Abstract

An earphone with a physiologic sensor includes a housing; a speaker in the housing; an enhancer comprising a body mounted on the housing and adapted to be secured in the ear to acoustically couple the speaker to the user'"'"'s ear; and an optical physiologic sensor disposed inside the enhancer, the enhancer having an aperture or window aligned with the optical physiologic sensor, so that the sensor can optically couple with the user'"'"'s ear when the enhancer is secured in the user'"'"'s ear.

Claims

1. An earphone with a physiologic sensor, comprising:

a housing;

a speaker in the housing;

an enhancer comprising a body mounted on the housing and adapted to be secured in the ear to acoustically couple the speaker to the user'"'"'s ear; and

an optical physiologic sensor disposed inside the enhancer, and at least one aperture in the enhancer aligned with the optical physiologic sensor, so that the sensor can optically couple with the user'"'"'s ear when the enhancer is secured in the user'"'"'s ear.

2. The earphone according to claim 1, wherein there are a plurality of apertures, arranged in an array.

3. The earphone according to claim 1, wherein the at least one aperture is in the portion of the enhancer that faces the concha of the user'"'"'s ear.

4. The earphone according to claim 1 wherein the at least one aperture is in the portion of the enhancer that faces the upwardly facing wall of the concha of the user'"'"'s ear.

5. The earphone according to claim 1 wherein the at least one aperture is in the portion of the enhancer that faces the forwardly facing wall of the concha of the user'"'"'s ear.

6. The earphone according to claim 1 further comprising at least one channel in the surface of the enhancer for directing sweat away from the at least one aperture.

7. The earphone according to claim 1 further comprising an absorbent patch for absorbing sweat from adjacent the at least one aperture.

8. An earphone with a physiologic sensor, comprising:

a housing;

a speaker in the housing;

an enhancer comprising a body mounted on the housing and adapted to be secured in the ear to acoustically couple the speaker to the user'"'"'s ear; and

an optical physiologic sensor disposed inside the enhancer, and at least one window in the enhancer aligned with the optical physiologic sensor, so that the sensor can optically couple with the user'"'"'s ear when the enhancer is secured in the user'"'"'s ear.

9. The earphone according to claim 8 wherein there are a plurality of windows, arranged in an array.

10. The earphone according to claim 8 wherein the at least one window is in the portion of the enhancer that faces the concha of the user'"'"'s ear.

11. The earphone according to claim 8 wherein the at least one window is in the portion of the enhancer that faces the upwardly facing wall of the concha of the user'"'"'s ear.

12. The earphone according to claim 8 wherein the at least one window is in the portion of the enhancer that faces the forwardly facing wall of the concha of the user'"'"'s ear.

13. The earphone according to claim 8 further comprising at least one channel in the surface of the enhancer for directing sweat away from the at least one aperture.

14. The earphone according to claim 8 further comprising an absorbent patch for absorbing sweat from adjacent the at least one window.

15. An earphone with a physiologic sensor, comprising:

a housing;

a speaker in the housing;

an enhancer comprising a body mounted on the housing and adapted to be secured in the ear to acoustically couple the speaker to the user'"'"'s ear; and

an optical physiologic sensor disposed inside the enhancer, and a deformable pillow on the enhancer, the pillow being transparent to the optical wavelengths used by the optical physiologic sensor, the pillow contacting and conforming to the user'"'"'s ear, so that the sensor can optically couple with the user'"'"'s ear when the enhancer is secured in the user'"'"'s ear.

16. An earphone with a physiologic sensor, comprising:

a housing;

a speaker in the housing;

an enhancer comprising a body mounted on the housing and adapted to acoustically couple the speaker to the user'"'"'s ear;

an ear loop for extending behind the ear to secure the earphone; and

a physiologic sensor comprising an optical transmitter on one of the housing and the earloop, and an optical receiver on the other of the housing and the earloop.
