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.

摘要： Displacement of a moving diaphragm in an electroacoustic transducer is measured by modulating an electrical signal based on changes in capacitance between the voice coil assembly and the magnetic structure resulting from relative motion between the voice coil and the magnetic structure. The modulated electrical signal is demodulated to produce an output signal having a value proportional to the displacement.

摘要： In an ANR circuit of a personal ANR device, a digital filter is structured to introduce one or more zeros to add gain to introduce positive phase in the provision of feedback-based ANR, wherein the gain follows a frequency-dependent “ski-slope” gain curve with little gain added at lower audible frequencies, with increasing gain that increases with frequency added at higher audible frequencies, and with the increasing gain flattening at frequencies above audible frequencies.

摘要： In a personal ANR device having a pair of earpieces, each having a feedforward microphone and an ANR circuit associated therewith, each ANR circuit provides digital data representing environmental noise sounds detected by each ANR circuit's associated feedforward microphone. Such digital data may represent the environmental noise sounds as detected with little or not modification, or such digital data may be modified to some degree within each ANR circuit, perhaps to limit the range of frequencies that such digital data represents, before being provided to the other ANR circuit.
