Embodiment Construction

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

[0012] This application proposes an embodiment of a moisture-resistant paper cone for a speaker, which at least includes a combination of polyvinyl chloride, polyester fiber, and lignin.

[0013] In the above examples, in parts by weight, there are 100 parts of polyvinyl chloride, 58-60 parts of polyester fiber, and 15-16 parts of lignin. Lignin can be extracted from various woods. The combination of polyester fiber and lignin can not only exert their respective advantages, but also synergistically produce new modification effects. The three components in this case can effectively improve the tensile strength, moisture resistance and elastic modulus of the paper cone. Increase the elastic modulus of the paper cone, reduce the loss coefficient of the paper cone, thereby reducing the di...

Abstract

The invention discloses a moisture-resistant paper cone for a loudspeaker. The moisture-resistant paper cone at least comprises a combination of polyvinyl chloride, polyester fiber and lignin. In the scheme, a material formula of a conventional paper cone is improved, and modified fiber is introduced, so that the defect of poor moisture resistance of a paper cone in the prior art is overcome. Moreover, the fiber and the lignin are improved together, so that the paper cone has superior structural strength, corrosion resistance and fatigue resistance, and the loudspeaker can keep relatively high fullness for a long time on a full band. Thus, distortion of the loudspeaker is restrained greatly, and the tone quality of the loudspeaker is enhanced.

Description

technical field [0001] The invention relates to an acoustic material, in particular to a moisture-resistant paper cone used for a loudspeaker. Background technique [0002] The paper cone is one of the main parts of the speaker, which has a decisive influence on the performance and sound quality of the speaker. In the speaker, the voice coil will vibrate strongly in the magnetic field after the audio signal is connected. The voice coil is fixed on the paper cone, and the vibration of the voice coil drives the vibration of the paper cone at the same time. The vibration of the paper cone forces the air to vibrate, thereby producing sound. [0003] The paper cones used in traditional loudspeakers mainly have 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] Aiming at the deficie...
