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; an electroacoustic transducer disposed within the housing; and an expansion unit having an upper portion and at least three coupling elements coupling the upper portion to the housing, the upper portion having a substantially convex curvature for bearing against a crus inferius anthelicis when the in-ear earphone is secured to an ear of a user, a first coupling element of the at least three coupling elements extending from the housing toward the upper portion in a substantially convex shape, a second coupling element of the at least three coupling elements extending from the housing toward the upper portion in a substantially concave shape, the second coupling element and the upper portion tapering together at distal ends to join at a peak, and a third coupling element of the at least three coupling elements disposed between the first coupling element and the second coupling element.
