摘要： Personal speaker systems including headset and earbud systems may be configured to capture audio data using an in-ear microphone while a speaker outputs known audio signals into the ear canal. The system may generate an acoustic model of the compressed ear canal and ear drum of the listener and utilize the acoustic model to provide noise cancellation at the eardrum, modification to the audio to result in a more natural sound at the eardrum, and/or to measure leakage of the personal speaker system.

摘要： Devices for improving the quality of sound output by a speaker. For example, the device may act to remove ultrasonic frequencies from an audio signal prior to the audio signal being output by a speaker. In other examples, the device may act to impede the progress of harmonic distortion, intermodulation distortion, and environmental noise feeding back into the source device.

摘要： An impedance matched resonant circuit uses inductors coupling an audio source and a speaker array in order to reduce feedback reflection induced by an audio signal traveling from the audio source to the array of speakers. An RC circuit could also be coupled to the positive and negative terminals of the speaker array to reduce the slope differential of the audio signal at certain frequencies. The circuit can be packaged together in a single module with switches to activate and deactivate portions of the circuit to alter the effectiveness of the circuit depending upon need.
