Patent number: 11688382Abstract: Noise-canceling audio devices may include a first vibration member, a second vibration member, and a microphone supported by a housing. A feedback, noise-cancelation circuit may be operatively connected to the microphone, the feedback, noise-cancelation circuit configured to generate a first portion of a modified audio signal by combining an audio signal with a noise-canceling signal generated in response to a signal from the microphone to at least partially cancel at least a portion of an audible response of the second vibration member. A feed-forward, noise-cancelation circuit may be operatively connected to the microphone, the feed-forward, noise-cancelation circuit configured to compare the signal from the microphone to a predetermined SPL profile and generate a second portion of the modified audio signal configured to at least partially cancel environmental noise, the feedback, noise cancelation circuit configured to output the modified audio signal only to the first vibration member.Type: GrantFiled: May 17, 2022Date of Patent: June 27, 2023Assignee: Skullcandy, Inc.Inventors: Randall J. Hull, Branden Sheffield, John Timothy

Patent number: 11335313Abstract: 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 a portion of an 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.Type: GrantFiled: December 2, 2020Date of Patent: May 17, 2022Assignee: Skullcandy, Inc.Inventors: Randall J.

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.Type: GrantFiled: December 15, 2017Date of Patent: December 22, 2020Assignee: Skullcandy, Inc.Inventors: Randall J.

Patent number: 10587946Abstract: 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.Type: GrantFiled: December 5, 2017Date of Patent: March 10, 2020Assignee: Skullcandy, Inc.Inventors: Branden Sheffield, John Timothy, Randall J.

Patent number: 10462560Abstract: 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.Type: GrantFiled: January 8, 2018Date of Patent: October 29, 2019Assignee: SkullCandy, Inc.Inventors: John Timothy, Branden Sheffield, Randall J. Hull, Sam Noertker, Gregory R. Woolston, Andrew Pierce
