Abstract
Batteryless noise canceling headphones include a first earpiece having a first speaker for providing a first audio output to a first ear of a user in response to a first audio output signal, and having a first microphone element for converting a first ambient audio input at the first ear into a first ambient audio input signal in response to a bias voltage. A connector receives the bias voltage from an audio device, receives the first audio output signal from the audio device, and provides the first ambient audio signal to the audio device.
Claims17
An audio device comprising:
- an audio signal generator for generating an audio signal;
- a noise cancellation module for processing a first ambient audio input signal from batteryless noise canceling headphones into a first cancellation signal and for mixing the audio signal with the first cancellation signal to produce a first audio output signal;
- a connector, operably coupled to the noise cancellation module, for providing the first audio output signal and a bias voltage to the batteryless noise canceling headphones and for receiving the first ambient audio input signal from the batteryless noise canceling headphones when the batteryless noise canceling headphones are connected thereto.
Batteryless noise canceling headphones comprising:
- a first earpiece having a first speaker for providing a first audio output to a first ear of a user in response to a first audio output signal, and having a first microphone element for converting a first ambient audio input at the first ear into a first ambient audio input signal in response to a bias voltage;
- a connector, operably coupled to the first speaker and the first microphone, for connecting to an audio device, the connector for receiving the bias voltage from the audio device, for receiving the first audio output signal from the audio device, and for providing the first ambient audio signal to the audio device.
A method comprising:
- generating an audio signal in an audio device;
- receiving a first ambient audio input signal from batteryless noise canceling headphones when the batteryless noise canceling headphones are connected to the audio device;
- processing the first ambient audio input signal from the batteryless noise canceling headphones into a first cancellation signal when the batteryless noise canceling headphones are connected to the audio device;
- mixing the audio signal with the first cancellation signal to produce a first audio output signal;
- and
- providing the first audio output signal and a bias voltage to the batteryless noise canceling headphones when the batteryless noise canceling headphones are connected to the audio device.
