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.
