Abstract:
1. A multi-transducer earpiece for an audio reproduction apparatus, the earpiece including: a sound delivery member with an acoustic delivery channel having a cross section area, a first end of the sound delivery member being for placement of an ear bud, the ear bud being locatable at an entrance of an ear canal of a user; a sound damper for mounting the sound delivery member; a first single sound delivery tube and a second single sound delivery tube located in the sound damper, a perpendicular flange which is integral to the sound damper, the flange for partitioning the cross sectional area of the acoustic delivery channel into an extension of the first single sound delivery tube and an extension of the second single sound delivery tube when the sound delivery member is mounted onto the sound damper, the extension of the first single sound delivery tube being separated from the extension of the second single sound delivery tube by only the flange, and the breadth of the perpendicular flange is at least as lengthy as the diameter of each of the first and second sound delivery tube; a high frequency transducer having a first output positionable to be co-axial with the first single sound delivery tube; and a mid or low frequency transducer having a second output positionable to be co-axial with the second single sound delivery tube; wherein mixing of signals from the first and second outputs is carried out in the ear canal of a user during reproduction of audio signals.
