Abstract
An audio system comprises: a first earpiece comprising at least one acoustic driver, and circuitry that comprises at least one microphone; a housing configured to receive the first earpiece and enclose around the first earpiece; an acoustic cavity within the housing configured to provide a predetermined volume that is acoustically coupled to the acoustic driver when the first earpiece is housed within the housing. The first earpiece or the housing comprises circuitry configured to: (1) measure a response from the microphone to an acoustic wave, and (2) calibrate the circuitry based at least in part on the measured response.

An audio system comprising:
- a first earpiece comprising at least one acoustic driver, and circuitry that comprises at least one microphone;
- a housing configured to receive the first earpiece and enclose around the first earpiece;
- an acoustic cavity within the housing configured to provide a predetermined volume that is acoustically coupled to the acoustic driver when the first earpiece is housed within the housing;
- wherein the first earpiece or the housing comprises circuitry configured to:
- (1) measure a response from the microphone to an acoustic wave, and (2) calibrate the circuitry based at least in part on the measured response.
A method for calibrating wearable audio devices, the method comprising:
- providing a first signal to generate a first acoustic wave from an acoustic driver in a first earpiece;
- measuring a response from a microphone in a second earpiece to the first acoustic wave;
- calibrating circuitry in the first earpiece based at least in part on the measured response from the microphone in the second earpiece;
- providing a second signal to generate a second acoustic wave from an acoustic driver in the second earpiece;
- measuring a response from a microphone in the first earpiece to the second acoustic wave;
- and
- calibrating circuitry in the second earpiece based at least in part on the measured response from the microphone in the first earpiece.
A case for a wearable audio device comprising:
- a housing configured to receive a first earpiece in a first portion of the housing and configured to receive a second earpiece in a second portion of the housing;
- an acoustic cavity within the housing configured to provide a predetermined volume that is acoustically coupled to the first portion of the housing and to the second portion of the housing;
- and
- an acoustic passage configured to acoustically couple an acoustic driver in the first earpiece to a microphone in the second earpiece.
