Abstract:
A loudspeaker assembly, comprising:an acoustic diaphragm having at least one laminated structure, one of which includes a first carbon fiber layer, a glue layer formed on said first carbon fiber layer, and a second carbon fiber layer formed on said glue layer; and a driving device arranged to face said acoustic diaphragm for providing a sound wave signal to vibrate said acoustic diaphragm so as to allow sound to travel in the air, wherein said driving device faces said acoustic diaphragm at an intersection of a vertical line passing a point which is {fraction (3/11)} of the distance from a center of gravity of said acoustic diaphragm to one side edge of said acoustic diaphragm, and a horizontal line passing a point which is {fraction (2/9)} of said distance from said center of gravity to one of the upper and lower edges.
