  • Publication number: 20200068307
    Abstract: Methods of operating headphones may involve filtering an input signal into a first filtered input signal and a second filtered input signal utilizing a filter. The second filtered input signal may be sent directly to a tactile vibration driver and tactile vibrations may be produced. A fixed, predetermined inverse transfer function may be applied to the first filtered input signal, generating an anti-wave signal. The anti-wave signal may be summed with the first filtered input signal, generating an output signal. Alternatively, a fixed, predetermined transfer function may be applied to the first filtered input signal, generating a modified input signal. The modified input signal may be subtracted from the first filtered input signal, generating an output signal. Audio sound waves may be produced with an acoustic driver responsive to the output signal, reducing effects of incidental acoustic noise generated by the tactile vibration driver.

  • Patent number: 10484792
    Abstract: A headphone that may reduce acoustic noise from a tactile vibration driver includes a housing, and an acoustic driver and tactile vibration driver within the housing. The tactile vibration driver is configured to generate tactile vibration sufficient to be felt by a user responsive to the input signal. The headphone also includes a noise cancellation unit coupled with the acoustic driver, the noise cancellation unit configured to: generate an adjustment signal based, at least in part, on a transfer function associated with the tactile vibration driver generating acoustic noise incidental to the tactile vibrations; and adjust the input signal responsive to the adjustment signal to transmit an output signal for reproduction by the acoustic driver. Related methods for operating and making such headphones are also disclosed.

  • Patent number: 10462560
    Abstract: A driver assembly comprises a housing structure, a magnet assembly within the housing structure, and opposing spring structures coupled to the housing structure at different vertical positions than one another. The magnet assembly comprises a permanent magnet, a plate structure underlying the permanent magnet, a voice coil circumscribing the permanent magnet and the plate structure, and a yoke structure at least partially surrounding the permanent magnet, the plate structure, and the voice coil. The opposing spring structures are configured to impede horizontal movement of the permanent magnet, the plate structure, and the yoke structure while permitting vertical movement thereof. A headphone and a method of forming a headphone are also described.

  • Patent number: 10375466
    Abstract: In one embodiment, a gain redistribution application restructures gains associated with multiple microphones included in a head-worn audio system to minimize near field noise. In response to a sound generated by a sound source, the microphones generate input signals. The gain redistribution application performs mixing operations on the input signals to generate an output signal that mitigates near field noise associated with the same side of the head as the sound source. Subsequently, the gain redistribution application transmits the output signal to a speaker that targets the same side of the head as the sound source. Advantageously, by reducing the gain associated with an input signal received via a microphone located on the same side of the head as the sound source, the gain redistribution application reduces near field noise transmitted to the user during operation in a more comprehensive fashion relative to conventional designs.

  • Publication number: 20190189106
    Abstract: Noise-canceling headphones may include a headband, an audio input, and earcups supported proximate ends of the headband. A first vibration member operatively connected to the audio input, a second vibration member operatively connected to the audio input, and a microphone may be supported by a housing of at least one of the earcups. A feedback, noise-cancelation circuit configured to reduce a user's perception of an undesirable audible response of the second vibration member may be operatively connected to the microphone. The feedback, noise-cancelation circuit may be configured to modify an audio signal from the audio input at least in part based on a signal from the microphone and send the modified audio signal to the first vibration member. The modified audio signal may be configured to at least partially cancel at least a portion of an audible response of the second vibration member.

  • Patent number: 10045107
    Abstract: One or more embodiments set forth include a personal aural device that includes an expandable eartip. The expandable eartip has a contracted state and an expanded state. The expandable eartip includes an insertion sensor configured to receive an indication that the eartip has been placed in an ear of a user. The expandable eartip further includes a controller configured to, in response, actuate a first device to inflate a first chamber to conform to a first portion of the ear. At least one advantage of the described techniques is that eartips in a set of earphones automatically inflate to provide an optimal fit for any listener's ears.

  • Publication number: 20160255436
    Abstract: A first digital signal processor (DSP) associated with a first user outputs audio to the first user via first headphones, and captures speech from the first user via a first microphone. Similarly, a second DSP associated with a second user outputs audio to the second user via second headphones, and captures speech from the second user via a second microphone. The first DSP is coupled to the second DSP in order to allow the first and second users to share music and communicate with one another. The first user may speak into the first microphone, and the first and second DSPs may then interoperate to output that speech to the second user without substantially disrupting audio output to the second user. Each of the first and second users may also select between first and second audio sources that may be coupled to the first and second DSPs, respectively.
