Abstract
An earphone body includes an internal chamber, a transducer housed in the internal chamber, a first tuned vent and a second tuned vent. The transducer has a front surface facing a direction of insertion of the earphone body in use and a rear surfaceB. The internal chamber provides a proximal acoustic volume adjacent the front surface of the transducer and a distal acoustic volume adjacent the rear surface of the transducer. The first tuned vent and the second tuned vent each extend between the distal acoustic volume and the ambient environment and are adapted to provide fluid communication between the distal acoustic volume and the ambient environment. The first tuned vent is tuned to a first frequency and the second tuned vent is tuned to a second frequency, the first frequency being lower than the second frequency.
