摘要： A pair of in-ear headphones is disclosed that are operable to reproduce incoming audio signals. The in-ear headphones include an oval shaped housing defining an internal chamber. A front portion of the oval shaped housing defines a nozzle extending away from the housing. A driver is positioned in the internal chamber such that a sound reproduction portion of the driver is aligned with an internal audio channel running through the nozzle. A damper is positioned in an end of the nozzle having a damper aperture having a predetermined size. The nozzle extends from a base portion of the housing at a predetermined upward angle and a predetermined bend angle that provides improved audio frequency responses in desirable frequency ranges.
摘要翻译：公开了可操作以再现输入音频信号的一对入耳式耳机。入耳式耳机包括限定内部腔室的椭圆形壳体。椭圆形壳体的前部限定了远离壳体延伸的喷嘴。驱动器位于内部室中，使得驾驶员的声音再现部分与穿过喷嘴的内部音频通道对准。阻尼器位于具有预定尺寸的阻尼器孔的喷嘴端部。喷嘴从壳体的基部以预定的向上的角度和预定的弯曲角度延伸，其在期望的频率范围内提供改善的音频响应。

摘要： According to an aspect of the disclosure, a loudspeaker includes an enclosure. The enclosure includes a first plurality of sidewalls. The loudspeaker further includes a horn. The horn is defined in part by the first plurality of sidewalls. The horn includes a second plurality of sidewalls that are coupled to the first plurality of sidewalls and that include a first sidewall and a second sidewall. The horn further includes a motorboard that includes a first opening arranged along a plane and a second opening arranged along the plane. The motorboard is coupled to the first sidewall and the second sidewall. The loudspeaker further includes an active driver arranged concentric to the first opening to transmit sound waves directly through the first opening, and a passive component arranged concentric to the second opening to transmit sound waves directly through the second opening.

摘要： A noise distortion control system for an active noise-cancelling device includes a body that forms an enclosed acoustic cavity. The body includes a driver, a microphone having a predetermined maximum sound pressure threshold, an active noise-cancelling system, and a processor coupled with the driver and the microphone. The processor is configured to monitor an input signal to the driver, and to reduce a gain of the active noise-cancelling system when the input signal to the driver exceeds the predetermined maximum sound pressure threshold.
