Abstract

The invention discloses a loudspeaker cone production device which comprises a base. The upper end of the base is fixedly connected with an upper box body. A cavity with a forward opening is formed inthe front end wall of the upper box body. A first movable plate is in sliding fit with the inner wall of the cavity. A second connecting rod is fixedly mounted on the lower end wall of the first movable plate. An upper mold is fixedly mounted at the lower end of the second connecting rod. Sleeves are symmetrically and fixedly mounted on the left and right sides of the lower end of the first movable plate. First movable rods are arranged in the sleeves in a sliding fit manner. First springs connected with the sleeves are fixedly mounted in the sleeves. The lower ends of the first movable rodsare fixedly connected with clamping blocks. Clamping grooves are formed in the positions, on the lower sides of the clamping blocks, of the upper end wall of the base. A groove is formed between the clamping grooves in the left side and the right side. A water cavity is formed in the lower side of the groove. A first movable cavity is formed in the lower side of the water cavity. A second movableplate is in sliding fit with the inner wall of the first movable cavity and connected with the bottom wall of the first movable cavity through second springs.

Description

Technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a speaker cone production device. Background technique [0002] The loudspeaker is a very commonly used electrical transducer device, which can be seen in electrical and electronic equipment of France or energy. The most common one in life is an electric cone-shaped paper cone speaker, which is usually composed of a magnet, a frame, a centering support piece, and a molded ring cone-shaped paper cone. The paper cone makes the sound radiating device of the loudspeaker, to a considerable extent, determines the release performance of the loudspeaker. The paper cone of any material must be light and rigid, and cannot be deformed due to changes in ambient temperature and humidity. . At this stage, most of them are molded by emulsified rosin glue, but there is no good molding device at this stage. Summary of the invention [0003] In view of the above technical shortcomings, the prese...
