An earphone includes a loudspeaker, a microphone, a housing supporting the loudspeaker and microphone, and an 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 receives input audio signals from the microphone, detects peaks having a frequency of around 1 Hz in the input audio signals, based on the detected peaks, computes an instantaneous heart rate, measures a frequency of an oscillation within the instantaneous heart rate, and based on the frequency of the oscillation, computes a rate of respiration.

Measuring respiration with an in-ear accelerometer

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.

Earphones for measuring and entraining respiration

Aspects of the present disclosure provide a method for obtaining biological information associated with a user, comprising receiving electrical signals via a first electrode on an ear tip of an earpiece inserted in an ear of the user, receiving electrical signals via a second electrode on an external portion of the earpiece, and deriving an electrocardiogram (ECG) based on the signals received via the first electrode and the second electrode. Aspects also provide a method for determining a pulse travel time (PTT) associated with a user, comprising obtaining a proximal signal using an earpiece inserted in of the user, obtaining a distal signal using the earpiece, and deriving the PTT based on the obtained proximal signal and the obtained distal signal.

Collecting biologically-relevant information using an earpiece

Aspects of the present disclosure provide an audio product for obtaining biologically-relevant information associated with a user comprising. The audio product includes at least two electrodes, a processor, and an electroacoustic transducer coupled to the processor. The processor is configured to receive at least one signal affected by an action of the user obtained via the first electrode or the second electrode and take one or more actions based on the at least one signal. The at least one action may control another device, in an effort to provide hands-free control of the other device.

An air adsorbing and sound absorbing structure with a first portion comprising a first material comprising an open-celled foam with an air-adsorbing material coupled to the foam, where the first portion has a first air adsorption capacity and a first density. There is a second portion fixed to or integral with the first portion, wherein the second portion comprises one or more of: a different material than the first material, a second air adsorption capacity that is different than the first air adsorption capacity, and a second density that is different than the first density.

Air adsorbing and sound absorbing structure

A transducer suspension element is presented. The transducer suspension element includes a suspension member having a body, the body having a main portion, a first portion extending from the main portion and continuing to an outer edge, and a second portion extending from the main portion and continuing to an inner edge. At least one conductor is disposed within or on the suspension member body, the at least one conductor extending at least within a section of the first portion and within a section of the second portion of the suspension member, and wherein a length of the at least one conductor of the suspension member is greater than a minimal distance from the inner edge to the outer edge across the suspension member.
