The invention relates to a two dimension curved surface piezoelectric composite material element manufacturing method which comprises two manufacturing technologies. One of the technologies comprises the following steps: two dimension curved surface dies are added on upper and lower surfaces of a ceramic ceramic array which is formed via cutting operation, and the upper and lower surfaces are subjected to two dimension curved surface bending formation operation; after an upper die is released, resin is poured and is subjected to curing molding operation, and then a two dimension curved surface composite material is formed; upper and lower dies and a lining membrane are released to form a sensing element. Another manufacturing technology comprises the following steps: a face, positioned in a polarization direction, of a piezoelectric ceramic is subjected to bidirectional cutting operation of a certain cut thickness; the face is filled with a flexible material; a face, opposite to the face filled with the flexible material, of the ceramic is subjected to the bidirectional cutting operation; a two dimension curved surface die is added on the face filled with the flexible material; the resin is poured in the newly cut face, and another two dimension curved surface is added on the newly cut face; at a last step, the two dimension curved surface sensing element is formed via curing operation. The two dimension curved surface piezoelectric composite material element manufacturing method can be used for manufacturing a two dimension curved surface-shaped piezoelectric composite material, and sound waves can be radiated horizontally and vertically in an omnidirectional manner.
