Abstract: The disclosure relates to an in-ear wearable device, including: a customized housing having a housing wall and an inner cavity, the customized housing comprising a first portion for being inserted into an user's acoustic meatus and a second portion for being exposed to the external when in use; a panel mounted to the customized housing; a ventilation hole at least partially disposed in the customized housing and partially formed in the housing wall; and a ventilation rate adjusting device mounted in the ventilation hole. The ventilation hole and the ventilation rate adjusting device constitute at least a part of a ventilation channel which is isolated from the inner cavity. The ventilation channel fluidly connects the acoustic meatus to the external when the user wears the in-ear wireless earphone. The ventilation rate of the ventilation channel can be electrically adjusted to adjust audio characteristics.

Abstract: The present disclosure relates to a wireless listening device, which includes a housing adapted to be wearable and a top cover. The top cover closes the housing at an end of the device and is provided with a central bumped portion that includes: a substantially planar panel portion; and a raised portion, which is connected around an outer periphery of the panel portion and at least partially extends toward the housing in a direction perpendicular to a plane where the panel portion is located. The panel portion and the raised portion form an accommodating groove that at least partially accommodate a charging device, a manipulation device and an antenna. In the plane where the panel portion is located, a diameter of a minimum circumscribed circle of orthographic projections of the charging device, the manipulation device, and the antenna as a whole is in a range of 8 to 16 mm.
