direction to the diaphragm 10 by the exciters 33 and 34 arranged on the arrow X1 direction side
and the arrow X2 direction side of the diaphragm 10 respectively. Stereo sound can be generated
by one diaphragm 10. Further, by disposing the fixing member 40 outside the region where the
image of the liquid crystal module 20 is displayed, the display quality of the image by the liquid
crystal module 20 is not degraded even if the fixing member 40 is provided. Further, by
arranging the fixing member 40 in the vicinity of the central portion in the horizontal direction of
the diaphragm 10, from the end portion of the fixing member 40 of the diaphragm 10 in the
arrow X1 direction side, the arrow X1 direction side of the diaphragm 10 The portion up to the
end of the can be configured to be vibratable. As a result, the area in which the diaphragm 10
can be vibrated can be made larger than in the case where the fixing member 40 is provided in
the vicinity of the exciters 33 and 34 disposed in the vicinity of both ends of the diaphragm 10.
