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, comprising:

a housing terminating in a front portion;

a speaker disposed in the front portion of the housing;

an enhancer comprising a body having an opening for receiving the front portion of the housing and extending outwardly beyond the front portion, the enhancer adapted to be secured in a user'"'"'s ear to acoustically couple the speaker to the user'"'"'s ear, the body including at least one aperture disposed over the speaker along a central axis of the body;

a sound tube projecting from the body offset from the central axis and adapted to fit in a user'"'"'s ear canal; and

an optical physiologic sensor disposed inside the enhancer behind the at least one aperture and behind the speaker so that the optical physiologic 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 a 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 a portion of the enhancer that faces an 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 a portion of the enhancer that faces a 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 a 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 an area adjacent the at least one aperture.

8. An earphone, comprising:

a housing terminating in a front portion;

a speaker disposed in the front portion of the housing;

an enhancer comprising a body having an opening for receiving the front portion of the housing and extending outwardly beyond the front portion, the enhancer adapted to be secured in a user'"'"'s ear to acoustically couple the speaker to the user'"'"'s ear, the body including at least one window disposed over the speaker along a central axis of the body;

a sound tube projecting from the body offset from the central axis and adapted to fit in a user'"'"'s ear canal; and

an optical physiologic sensor disposed inside the enhancer behind the at least one window and behind the speaker so that the optical physiologic 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 a 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 a portion of the enhancer that faces an 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 a portion of the enhancer that faces a 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 a 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 an area adjacent the at least one window.
