The invention discloses an improved horn production device. The device comprises a support frame, a die pressing groove is formed in the surface of a die pressing base, two templates are symmetricallyarranged at the two ends of the surface of the die pressing groove, a heating plate is installed on the upper surface inside a cover cap, a fixed box is fixedly installed on the portion, under a diepressing base block, of the lower surface of a die pressing platform plate, a cylinder is fixedly installed in the fixed box, a top block is fixedly installed at the upper end of a piston rod of the cylinder, the top block is movably inserted into a through hole, and a conveyor belt is installed in a delivery box. Accordingly, a material plate can be heated through the heating plate, the plasticity of the material plate can be improved, the vibrating membrane forming quality is improved, and meanwhile the die pressing efficiency is improved; after processing is completed, the piston rod of thecylinder moves upwards and can push a formed vibrating membrane out of the die pressing groove, the vibrating membrane can fall on the surface of the conveyor belt, and the manpower is greatly saved.
