Abstract

The vibrating diaphragm material comprises a vibrating diaphragm coating and a base material layer, and the vibrating diaphragm coating is formed by coating a vibrating diaphragm glue solution. The vibrating diaphragm glue solution is prepared from the following components in parts by weight: 50 to 80 parts of acrylic resin, 25 to 35 parts of polyethylene resin, 10 to 15 parts of ethylene propylene rubber, 3 to 5 parts of diethylene glycol monohexyl ether, 3 to 8 parts of isopropyl triphenyl phosphate, 15 to 20 parts of glass fiber, 1 to 3 parts of antioxidant, 1 to 5 parts of lubricant, 1 to 5 parts of 2-methyl-5-amino-N-ethyl benzenesulfonyl aniline and 100 parts of solvent. According to the diaphragm material disclosed by the invention, the diethylene glycol monohexyl ether and the isopropyl triphenyl phosphate are added into the acrylic resin, the polyethylene resin and the ethylene propylene rubber, so that the maximum pushing volume of a loudspeaker is increased and can be increased by 39% to the maximum; and the frequency response of the loudspeaker is improved and can be increased by 10dB at most.

Description

technical field [0001] The invention belongs to the technical field of diaphragm materials, and in particular relates to a diaphragm material and a preparation process thereof. Background technique [0002] The properties of the loudspeaker diaphragm material affect the sound quality. Common materials for diaphragms are: paper cones, synthetic plastics, and high-cost titanium diaphragms. [0003] At present, the paper cone manufacturing method is to pour the pulp into the designed mold, and then perform a series of subsequent processing after drying to form our common speaker unit diaphragm. The plastic diaphragm involves the electroplating process, and there is a certain amount of environmental pollution. The smelted alloy metal used in the metal diaphragm has certain toxicity and is difficult to recycle, which is harmful to the human body. [0004] Due to the characteristics of the material, the cone diaphragm is sensitive to changes in temperature and humidity. Changes...
