Abstract
An electronic device having an audio function and its loudspeaker arrangement are described. 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. Methods of operation and formation are also described.

48. An electronic device having an audio function, the electronic device comprising:
-
an exterior housing; a first acoustic radiator forming part of the exterior housing; an acoustic transducer coupled to the first acoustic radiator; and coupling means attached to an exterior surface of the first acoustic radiator, the coupling means being made from an elastomeric material, the first acoustic radiator being configured, when the electronic device is in a first mode of use, to radiate a first sound signal into free space in dependence on an electrical audio signal received by the acoustic transducer, and the coupling means being configured for acoustic coupling of the first acoustic radiator to a second acoustic radiator, when the electronic device is in a second mode of use, such that the second acoustic radiator is operative to radiate a second sound signal into free space in dependence on an electrical audio signal received by the acoustic transducer. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)

62. A method of radiating sound from an electronic device having an audio function when the electronic device is operated in one of two modes of use, the electronic device comprising an exterior housing, a first acoustic radiator forming part of the exterior housing, an acoustic transducer coupled to the first acoustic radiator, and a coupling means attached to an exterior surface of the first acoustic radiator, the coupling means being made from an elastomeric material, the method comprising:
-
locating the electronic device, in a first mode of use, such that a first sound signal is radiated into free space by the first acoustic radiator in dependence on an electrical audio signal received by the acoustic transducer; and locating the coupling means against a second acoustic radiator, in the second mode of use, such that the coupling means acoustically couples the first acoustic radiator to the second acoustic radiator, whereby the second acoustic radiator is operative to radiate a second sound signal into free space in dependence on an electrical audio signal received by the acoustic transducer.
