| 摘要 | An earphone has a housing, with a speaker mounted within the housing. A cable inlet contains a cable that includes a wire connected to the speaker. The cable and the cable inlet have different cross-sectional shapes, such that the cable is in contact with the inner surface of the cable inlet over a substantial portion of their length, while a rear volume of the speaker is vented through the cable inlet. This ensures that the cross-sectional area through which the rear volume is vented through the cable inlet remains relatively constant. The earphone may further comprise a microphone, positioned to detect ambient noise approaching the ear of a wearer of the earphone, and the cable may then further include a wire connected to the microphone. | ||

| 主权项 | 1. An earphone, comprising: an earphone housing; and a speaker mounted within the earphone housing; wherein the earphone comprises a cable inlet, comprising a cable that includes a wire connected to the speaker; and wherein the cable inlet has projections on an inner surface thereof, such that only a part of a cross-section of the cable is in contact with said projections on the inner surface of the cable inlet over a substantial portion of the length of the cable inlet, while a rear volume of the speaker is vented through the cable inlet. | ||
