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 vibration plate for a speaker, which at least includes a combination of polyester fiber, carbon fiber and abaca fiber.

[0013] In the foregoing embodiment, in terms of parts by weight, 100 parts of polyester fiber, 30 to 32 parts of carbon fiber, and 11 to 12 parts of abaca 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 vibration plate for a loudspeaker. The vibration plate at least comprises combination of polyester fibre, carbon fibre and aupoz fibre. In the scheme, the material formula of the vibration plate is improved; due to the introduced compound modified fibre, the relatively low moisture resistance of the vibration plate in the prior art is overcome effectively; furthermore, because the compound fibre is improved, the vibration plate has excellent structural strength, decay resistance and fatigue durability; the better plumpness of the loudspeaker can be kept in a full frequency band for a long time; therefore, 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 vibrating plate 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 vibrating plate for loudspeakers, which...
