  • Patent number: 10249287
    Abstract: A headphone includes a feedback microphone that receives a front air chamber sound including an external sound, the feedback microphone being provided on a front air chamber side, a driver unit that emits a noise-canceling sound into the front air chamber, the noise-canceling sound canceling at least a part of the sound included in the front air chamber sound received by the feedback microphone, a balanced microphone that receives the noise-canceling sound emitted from the driver unit, the balanced microphone being provided in a region on a side of the driver unit opposite the front air chamber, and a sound generating part that generates the noise-canceling sound by adding a signal based on the noise-canceling sound received by the balanced microphone to a signal based on the front air chamber sound received by the feedback microphone.

  • Patent number: 10204615
    Abstract: A noise-cancelling headphone is provided that avoids an influence of the wind and prevents degradation in the sound quality of the reproduced sound output from a driver unit. The noise-cancelling headphone includes an ear piece including a housing unit having an interior and an exterior, a driver unit attached to the housing unit, and a microphone collecting external sounds at the exterior of the housing unit. The housing unit includes an accommodating portion accommodating the microphone and a sound collecting hole establishing the communication between the accommodating portion and the exterior of the housing unit. The accommodating portion is disposed in an upper portion of the housing unit of the noise-cancelling headphone when worn by the user. The sound collecting hole is open toward the upper side of the housing unit of the noise-cancelling headphone when worn by the user.

  • Patent number: 9913020
    Abstract: A noise-cancelling headphone is provided that prevents degradation in the sound quality of the sound output from the driver unit caused by the sounds leaking through the vent hole for adjusting the sound quality. The noise-cancelling headphone includes a housing unit having an interior and an exterior, a driver unit attached to the housing unit, and a microphone collecting sound at the exterior of the housing unit. The housing unit includes an accommodating portion accommodating the microphone and a vent hole establishing communication between an air chamber behind the driver unit and the exterior of the housing unit. The housing unit is constructed such that emitted sounds from the vent hole are prevented from being collected by the microphone.
