Earphones For Measuring And Entraining Respiration
An earphone includes a loudspeaker, a microphone, a housing supporting the loudspeaker and microphone, and ear tip surrounding the housing and configured to acoustically couple both the loudspeaker and the microphone to an ear canal of a user, and to acoustically close the entrance to the user's ear canal. A processor provides output audio signals to the loudspeaker, receives input audio signals from the microphone, extracts a rate of respiration from the input audio signals, adjusts the output audio signals based on the extracted rate of respiration, and provides the adjusted output audio signals to the loudspeaker.
Claim CLM-00001. 1. A method of adjusting sounds heard by a user of an earphone, the method comprising:
providing output audio signals to a loudspeaker supported by a housing and acoustically coupled to the user's ear canal by an ear tip surrounding the housing and acoustically closing the entrance to the user's ear canal; receiving input audio signals from a microphone in the housing and also acoustically coupled to the user's ear canal by the ear tip; and in a processor
extracting a rate of respiration from the input audio signals;adjust the output audio signals based on the extracted rate of respiration; andprovide the adjusted output audio signals to the loudspeaker.
