Claim 11:
12. A seat assembly according to claim 10, wherein:
a headrest includes two loudspeakers, wherein the two loudspeakers each include:
a diaphragm;
a frame, wherein a proximal end of the diaphragm is suspended from the frame by at least one proximal suspension element, wherein the at least one proximal suspension element is configured to substantially prevent translational movement of the proximal end of the diaphragm relative to the frame, whilst permitting translational movement of a distal end of the diaphragm which is opposite to the proximal end of the diaphragm; and
a drive unit configured to move the distal end of the diaphragm based on an electrical signal;
wherein the seat is configured to position a user who is sat down in the seat such that a first ear of the user is located at a listening position that is in front of and 50 cm or less from the first radiating surface of the diaphragm of a first of the two loudspeakers, and such that a second ear of the user is located at a listening position that is in front of and 50 cm or less from the first radiating surface of the diaphragm of a second of the two loudspeakers.
