发明名称 In-ear earpiece and expansion adaptor
摘要 There is provided an in-ear earphone having a housing for receiving an electroacoustic transducer and an expansion adaptor unit which is coupled to the housing of the in-ear earphone. The expansion adaptor unit has an expansion unit with an upper portion having a curvature for fitting into a crus inferius anthelicis, an anti-helix and/or a concha of an ear of a user. The expansion adaptor unit further has at least one coupling element for coupling the upper portion to the housing of the in-ear earphone, wherein the expansion unit has at least two flexible legs as coupling elements, wherein one leg is coupled to a first end of the upper portion and a second leg is coupled to a second end of the upper portion.

主权项 1. An in-ear earphone comprising: a housing for receiving an electroacoustic transducer; and an expansion adaptor unit coupled to the housing of the in-ear earphone, wherein the expansion adaptor unit has an expansion unit having a substantially shark fin shape that includes an upper portion with a curvature for fitting in a crus inferius anthelicis, in an anti-helix, and in a concha of an ear of a user, and one or more flexible coupling elements for coupling the upper portion to the housing of the in-ear earphone, wherein the upper portion has a first end and a second end and one of the one or more flexible coupling elements is coupled to the second end, the upper portion having a substantially convex shape beginning at the second end and extending toward the housing, and the one of the one or more flexible coupling elements having a substantially concave shape beginning at a coupling point with the second end and extending toward the housing, wherein the concave shape of the one of the one or more flexible coupling elements has a radius of curvature that is smaller than a radius of curvature of the convex shape of the upper portion, and wherein the curvature of the upper portion is selected to fit in the crus inferius anthelicis and the anti-helix of the ear of the user, and the second end of the upper portion bears against the crus inferius anthelicis, the second end forming a tip for fitting into a volume formed on three sides by a crus helicis, a cymba conchae and a crus inferius anthelicis of the ear of the user.
