  • Patent number: 10587946
    Abstract: A headphone that may be operated in either a wireless mode or a wired mode includes a housing and an acoustic driver within the housing. The headphone includes a jack for receiving a complementary jack at the end of an audio cable, and at least one control input. The at least one control input controls operation of the headphone when the headphone is operated in the wireless mode, and the at least one control input controls operation of an associated media device when the headphone is operated in the wired mode. A method of method of operating a headphone includes using at least one control input on a headphone to control operation of the headphone while using the headphone in a wireless mode, and using the at least one control input on the headphone to control operation of an associated media device while using the headphone in a wired mode.

  • 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.

  • 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.
