The invention relates to a method for generating sound for a rotating machine, including a step (E) of determining the frequencies and amplitudes of n partials and/or harmonics (i) pertaining to the sound of a rotating machine, characterized in that the method includes a step (E) of determining values (a1) and a step (E-E) of calculating a synthetic sound for the rotating machine, said synthetic sound being composed from the n partials and/or harmonics (i), while the frequency thereof is entirely or partially shifted by the values (ai).

Generating sound for a rotating machine of a device

The invention relates to a voice coil support () for a coil transducer motor structure () having a first surface () towards one end and a second surface () towards the other end along an axis of displacement Z, the voice coil support being adapted to receive at least one coil (H,L) wound therearound an outer surface () arranged in use for displacing the voice coil support () along its axis of displacement Z, as a current is driven through the coils (H,L) when the voice coil support () is placed in a magnetic field, characterized in that the voice coil support () comprises a material adapted to prevent airflow communication between at least the first surface () and the second surface ().
