摘要：
Intra-concha earphones are disclosed. In an embodiment, an intra-concha earphone includes a housing having a rear space divided into a back volume, a bass duct, and a vent chamber between a driver and a rear wall. The vent chamber may be acoustically coupled with the back volume through both an acoustic port and the bass duct. Furthermore, the vent chamber may be acoustically coupled with a surrounding environment through a vent port, which may be a sole acoustic opening in the rear wall. Thus, sound emitted by the driver may propagate through the acoustic port and the bass duct to meet in the vent chamber before being discharged through the vent port to the surrounding environment. Other embodiments are also described and claimed.
摘要（中）：
公开了耳塞式耳机。 在一个实施例中，耳塞式耳机包括壳体，该壳体具有分为背部体积的后部空间，低音管道和驱动器与后壁之间的通风室。 通气室可以通过声学口和低音管道与后部体积声学耦合。 此外，通气室可以通过排气口与周围环境声学耦合，排气口可以是后壁中的唯一声学开口。 因此，驾驶员发出的声音可以通过声学口和低音管道传播，以便在通过排气口排放到周围环境之前与排气室相遇。 还描述和要求保护其他实施例。
