US 11,463,798 B2 · Headphone operation during headphone insertion detection

Abstract

A method of operating a headphone configured to be removed from and placed in close proximity to a user's ear can include generating an input signal by an input signal generating device. The method can also include determining whether an insertion event has occurred based on the generated input signal and causing the headphone to operate in 5 a low power mode responsive to an absence of an insertion event determination after a first period of time. The method can also include causing the headphone to operate in an ultra-low power mode responsive to the absence of an insertion event determination after a second period of time that occurs after the first period of time, the ultra-low power mode having a lower power consumption than the low power mode.

Dependent claims

An earbud having an earbud insertion detection system for detecting insertion of the earbud into a user's ear canal, the earbud comprising:

a microphone configured to convert an ambient sound wave to a first electrical audio signal;
a first filter configured to receive the first electrical audio signal from the microphone and produce a first modified audio signal based on first filter parameters;
a casing configured to support a transducer configured to convert a sensed pressure to a second electrical audio signal, the casing being further configured to maintain a position in the user's ear canal to maintain a position of the transducer within the user's ear;
a second filter configured to receive the second electrical audio signal from the transducer and produce a second modified audio signal based on second filter parameters;
and
a control circuit configured to determine whether either or both of the first and second modified audio signals exceeds a respectively corresponding signal level threshold.
