NON-OCCLUDING EARBUDS AND METHODS FOR MAKING THE SAME

摘要

Non-occluding earbuds and methods for making the same are disclosed. The earbud has a non-occluding housing having a directional port positioned offset with respect to a center axis of the housing. The directional port may be constructed to project acoustic signals into the user's ear canal. In addition, the directional port can include separate openings or ports for different front volumes existing within the housing. Front and back volumes can exist for each speaker contained within the housing, and embodiments of this invention use a midmold structure that enables the front volumes to be tuned independently of each other.
