Personalized calibration of an in-ear device
An in-ear device occludes an ear canal of an ear of a user. The in-ear device is configured to be calibrated such that the user perceives audio content as though the in-ear device is not occluding the ear canal. A transducer of the in-ear device presents audio content, and an inner microphone of the in-ear device detects sound pressure data within the ear canal. A controller of the in-ear device determines a blocked sound pressure at the entrance to the ear canal based on sound pressure data from an outer microphone. The controller generates sound filters custom to the user based in part on the detected sound pressure within the ear canal and the blocked sound pressure at the entrance to the ear canal. The controller adjusts audio content using the sound filter, and the transducer presents the adjusted audio content to the user.

CUSTOMIZABLE EAR INSERT
The present invention provides a customizable ear insert for fitting within a user's outer ear or ear canal or both and methods therefor. In accordance with an aspect of the present invention, there is provided a customizable ear insert having: a body formed of photocurable polymer, the body having a first shape configured for insertion into the outer ear canal of a user; a light source, the light source positioned adjacent the body, and wherein the body can be cured into a second shape by application of light generated by the light source, the second shape snugly conforming to the interior surface of the user's outer ear or ear canal or both.
Headset on ear state detection
A method and device for detecting whether a headset is on ear. A probe signal is generated for acoustic playback from a speaker. A microphone signal from a microphone is received, the microphone signal comprising at least a portion of the probe signal as received at the microphone. The microphone signal is passed to a state estimator, to produce an estimate of at least one parameter of the portion of the probe signal contained in the microphone signal. The estimate of the at least one parameter is processed to determine whether the headset is on ear.
Earpiece for determining state of closing element for vent
A system comprising an earpiece, the earpiece having a first end facing a tympanic membrane, and a second end facing toward a surrounding of a user when the earpiece is worn by the user, includes: a vent channel coupled to a first vent opening at the first end, and to a second vent opening at the second end, wherein the vent channel comprises a vent port; a closing element comprising a first magnetic member, the closing element configured to cause the vent port to be open, and to cause the vent port to be closed; an inductive member comprising a conductive material, the inductive member configured for inductive coupling with a second magnetic member, wherein the second magnetic member is configured for displacing the closing element by magnetic interaction with the first magnetic member; and a processor configured to obtain an electrical measurement value of the second magnetic member.
Atmospheric pressure adjustment apparatus and atmospheric pressure adjustment method of atmospheric pressure adjustment apparatus
An atmospheric pressure adjustment apparatus is disclosed. The atmospheric pressure adjustment apparatus comprises: a speaker; a microphone; an earplug of which a main body is made of an elastic material so as to seal the external auditory meatus when the earplug is worn on the ear of a user, and which comprises an atmospheric pressure adjustment part penetrating the main body; and atmospheric pressure adjustment device for adjusting the fluid volume of the atmospheric pressure adjustment part; and a processor for outputting a sound through the speaker when the earplug is worn, measuring the air pressure difference between the middle ear internal atmospheric pressure and the external auditory meatus atmospheric pressure of the user on the basis of the strength of a received echo when the echo of the sound reflected from the eardrum of the user is received through the microphone, and adjusting the atmospheric pressure difference by moving the atmospheric pressure adjustment device according to the measured atmospheric pressure difference.
