摘要： A system for providing binaural telepresence includes two communication devices, and two sets of active noise reducing headphones having an active noise-cancelling mode and an active hear-through mode, coupled to the respective communication devices and configured to provide left and right feed-forward microphone signals to the communication devices. The first communication device is configured to transmit the first left and right feed-forward microphone signals to the second communication device. The second communication device is configured to provide the first left and right feed-forward microphone signals to the second set of headphones. The second set of headphones are configured to activate their noise-cancelling mode while filtering the first left and right feed-forward microphone signals so that a user of the second set of headphones hears ambient noise from the environment of the first set of headphones, so that the user hears the ambient noise from the first set of headphones with ambient naturalness.

摘要： A method for adjusting the performance of an electroacoustic transducer includes receiving, by gain adjustment circuit, a displacement signal corresponding to a relative motion between a magnetic structure of the electroacoustic transducer and a voice coil of the electroacoustic transducer. The method includes detecting, by the gain adjustment circuit, a displacement signal value of the displacement signal as one of meeting or exceeding a displacement signal threshold. The method includes modifying, by the gain adjustment circuit, a loop gain of an active noise reduction loop associated with the electroacoustic transducer when the displacement signal value of the displacement signal one of meets or exceeds the displacement signal threshold.

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.

摘要： A method of conserving battery power includes providing an electrical conductor that is connectable between an audio source and an accessory of the audio source. The conductor is capable of conducting a first electrical signal, containing audio information from the audio source, to the accessory. A second electrical signal is applied to the conductor when the first electrical signal is not present on the conductor. An aspect of the second electrical signal is measured while it is being applied to the conductor. An amount of battery power supplied to the accessory is reduced when the measured aspect meets a predetermined condition.
