摘要:
There is provided an earphone comprising a housing having a fist and a second end. The housing has a first opening at the first end and a second opening at the second end for receiving an electroacoustic reproduction transducer. The earphone further has a second pressure reducing unit which is placed over the second opening to reduce the dynamic water pressure on the second opening, and a first pressure reducing unit which is placed over the first opening to reduce the dynamic water pressure on the first opening. In addition a second water-tight but acoustically transparent film is provided in the interior of the housing over the second opening to water-tightly close the second opening. A first water-tight but acoustically transparent film is placed in the interior of the housing over the first hole to water-tightly close the first hole.

There is provided an in-ear earphone having a housing (50) for receiving an electroacoustic transducer and an expansion adaptor unit (20) which is coupled to the housing (50) of the in-ear earphone. The expansion adaptor unit (20) has an expansion unit (20) with an upper portion (26) 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 (26) to the housing (50) of the in-ear earphone, wherein the expansion unit (20) has at least two flexible legs (22, 25) as coupling elements, wherein one leg (22) is coupled to a first end (28) of the upper portion (26) and a second leg (25) is coupled to a second end (29) of the upper portion (26).

An antistatic strapping apparatus for binding and securing a plurality of semiconductor device carrier trays, the apparatus including a strap member having opposed ends and a side defined as a top side spaced from a side defined as a bottom side and a major surface defined by the opposed ends and top and bottom sides. A loop portion of a hook and loop fastening combination constitutes the major surface area on the top side of the strap member. A piece of hook portion having the same width as the strap member of the book and loop fastening combination secured to the top side at a first end of the strap member, the hook portion extending the length of the strap member by at least about 80 mm. A conductive thread is sewn in a multiplicity of lengthwise tracks on the second side of the major surface to prevent build-up of static electricity. A “L” shaped buckle having a first transverse slot formed therethrough and near the end of the shorter leg, and a second transverse slot formed therethrough and near the end of the longer leg. The second end of the strap member is inserted through first slot of the “L” shaped buckle and folded back to itself, the bottom surface contain conductive thread tracks facing out, is sewn to secure the second end to the “L” shaped buckle.

There is provided an in-ear earphone comprising a housing (100), a transducer housing (200) and a support unit (300). The transducer housing (200) serves to receive an electroacoustic transducer. The support unit (300) is connected to the housing (100) and is adapted to be anchored in a concha of a wearer. The support unit (300) is at least partially made from a soft flexible material. In that way it can be ensured that the in-ear earphone can be anchored in any concha of a wearer.

An integrated circuit sorter automatically prevents the binning of a tested integrated circuit into a wrong container, such as a wrong tube, depending on the results of testing the integrated circuit. The automated integrated circuit sorter includes a respective switch for indicating that each output carries one of good or bad integrated circuits. A container identifier at each output identifies the type of container placed at the output. The container is determined to be for carrying good integrated circuits or bad integrated circuits. If the type of container placed at the output does not correspond to the type of integrated circuits at the output, then an integrated circuit stopper automatically blocks the admission of those integrated circuits into that container. The container identifier includes a light emitter and an optical sensor. A data processor determines whether a correct container or a wrong container is at the output. The data processor communicates with the integrated circuit sorter for affecting action of the integrated circuit stopper via the integrated circuit sorter. A data processor disable jumper may be coupled to the integrated circuit sorter to allow manual control of the integrated circuit stopper. Such a data processor disable jumper is especially advantageous in the event any component of the present invention is inoperative when the integrated circuit sorter may advantageously be manually controlled.
