Rubber voice diaphragm and method for preparing the same, and speaker

A rubber voice diaphragm, wherein components of the rubber voice diaphragm are composed of main rubber, a distortion improving agent, a vulcanizing agent, an accelerant, a reinforcing filler, and other processing aids;

• wherein the distortion improving agent is a substance with number-average molecular weight ranging from 1000 to 1000000, and a structure of the distortion improving agent has special chemical crosslinking points that participate in a rubber vulcanization reaction;
• the distortion improving agent is added in an amount of 0.1% to 100% based on mass of the main rubber;
• the special chemical crosslinking points are present in an amount of 0.01% to 30% based on mass of the distortion improving agent;
• a frequency band of the distortion improving agent for improving distortion range from 0.1 HZ to 20000 Hz;
• the vulcanizing agent is added in an amount of 0.001% to 10% based on the mass of the main rubber;
• the accelerant is added in an amount of 0.1% to 10% based on the mass of the main rubber;
• the reinforcing filler is added in an amount of 5% to 150% based on the mass of the main rubber;
• and
• the other processing aids are added in an amount of 1% to 50% based on the mass of the main rubber;
• and the other processing aids comprise one or more of a mold releasing agent, an antioxidant, an anti-aging agent, a plasticizer, a dispersant, an anti-scorching agent, a dispersing aid, and an activating agent.
