Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.

[0013] The invention provides a production process of a loudspeaker sound film. The production process of the sound film of a loudspeaker comprises the following steps during production:

[0014] First use a centrifugal grinder to grind the base material to a powder state below 3000 mesh, preferably, grind the base material to 2400-2500 mesh, and the base material includes fiber material, thermoplastic resin and adhesive , the fiber material is an organic fiber material or an inorganic fiber material, the mass percentage ratio of the fiber material and thermoplastic resin is (1-2):1, and the mass percentage ratio of the base material to the adhesive is ( 0.5~0.8): 1;

[0015] Then put the...

Abstract

A loudspeaker sound film production technology comprises the following steps: employing a centrifugal grinder to grind basic materials to powder in a centrifugal grinding mode, wherein the basic materials comprise fiber materials, thermoplastic resin and sticking agent, the fiber materials are organic fiber materials or inorganic fiber materials; putting the basic materials after grinding into a mixer, adding the sticking agent and the foaming agent at the same time, preparing the mixed sticking agent and the basic materials to paste materials through the mixer, forming micro bubbles in the mixed materials under the effect of the foaming agent, and heating the mixed materials to allow the micro bubbles to be expanded to form an enclosed bulb body; and finally, adding the paste-shaped mixture into a die cavity, performing heating forming through the extrusion technology to complete processing of a sound film. The foaming agent is added into the production materials to allow the mixed materials and the internal portion of the formed sound film to form micro bubbles so as to reduce the quality of the sound film and effectively increase the sound film elasticity while ensuring the rigidity of the sound film.

Description

technical field [0001] The invention relates to a production process of a loudspeaker assembly, in particular to a production process of a loudspeaker sound film. Background technique [0002] The speaker usually includes a sound film, a voice coil and a magnet. When the audio current flows through the voice coil, the voice coil is subjected to the magnetic field force of the magnet to produce a corresponding repeated movement, thereby driving the sound film to produce piston vibration, and then pushing the surrounding air to vibrate to produce sound. [0003] The performance of acoustic products currently on the market requires low distortion and high volume. The traditional speaker sound film can no longer be used, which means that the material side needs to develop high-strength and light-weight products to meet the needs of product upgrades. Contents of the invention [0004] Based on this, it is necessary to address the deficiencies in the prior art and provide a lo...
