The electronic device comprises an exterior housing, an acoustic transducer and an acoustic radiator forming a part of the exterior housing of the electronic device. In one embodiment, the exterior housing undergoes pistonic movement and is provided with hydrogel pads to couple an acoustic signal to an auxiliary surface, which then vibrates in a distributed mode. The voice coil may be directly bonded to the exterior housing. A formation may be provided to promote pistonic movement of a part of the exterior housing.
