摘要： In an active noise reducing headphone, a signal processor applies filters and control gains of both the feed-forward and feedback active noise cancellation signal paths. The signal processor is configured to apply first feed-forward filters to the feed-forward signal path and apply first feedback filters to the feedback signal path during a first operating mode providing effective cancellation of ambient sound, and to apply second feed-forward filters to the feed-forward signal path during a second operating mode providing active hear-through of ambient sounds with ambient naturalness.

摘要： Power is delivered from a power source in a head-mounted device to a separate accessory that is coupled to the head-mounted device. Power and signals are delivered on a common conductor that couples the head-mounted device to an accessory. One or both of the head-mounted device and the accessory are configured based on the signals. Power may be received at an accessory from the head-mounted device through a dedicated power conductor. Power may be delivered from a power source in a portable accessory to a head-mounted device that is coupled to the portable accessory and uses the power for circuitry in the head-mounted device that delivers audio to a user.
