Example Embodiment

[0011] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it according to the text of the description.

[0012] This case proposes an embodiment of a high-strength diaphragm for speakers, which at least includes a combination of polyester fiber, bamboo fiber and flax fiber.

[0013] In the foregoing embodiment, in terms of parts by weight, 100 parts of polyester fiber, 20-22 parts of bamboo fiber, and 15-16 parts of flax fiber. The combination of different fibers can not only exert their respective advantages, but also synergistically produce new modification effects. The three fibers in this case can effectively improve the structural strength, moisture resistance and elasticity of the vibration plate, and increase the elastic modulus of the vibration plate. , Reduce the loss coefficient of the diaphragm, thereby reducing the distortion of the speaker and improving the sound quality.

Abstract

The invention discloses a high-strength vibrating plate for a loudspeaker. The high-strength vibrating plate at least comprises a combination of polyester fiber, bamboo fiber and flax fiber. According to the high-strength vibrating plate disclosed by the invention, the material formula of the traditional vibrating plate is improved, the introduced composite modified fiber effectively overcomes the defect of relatively low moisture resistance of the vibrating plate in the prior art, moreover, due to the improvement of the composite fiber, the vibrating plate has excellent structural strength, corrosion resistance and fatigue resistance, and the loudspeaker can keep relatively good plumpness at the whole frequency band for a long time, so that the distortion of the loudspeaker is greatly inhibited, and the tone quality of the loudspeaker is improved.

Description

technical field [0001] The invention relates to an acoustic material, in particular to a high-strength vibration plate used for a loudspeaker. Background technique [0002] The vibration plate is one of the main parts of the speaker, which has a decisive influence on the performance and sound quality of the speaker. A vibration plate with excellent performance needs to have a light weight, which can improve efficiency and have good transition characteristics; at the same time, it needs to have a large Yankee coefficient to expand the bandwidth. [0003] The vibration plate used in traditional loudspeakers has the following defects: 1) poor moisture resistance; 2) poor structural stability; 3) low elastic modulus and poor fatigue resistance. These factors can seriously affect the speaker's performance and sound quality. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a high-strength vibrat...
