preparation example Construction

[0033] The invention proposes a method for preparing a loudspeaker diaphragm, aiming at solving the problem of large distortion and easy deformation of the existing loudspeaker diaphragm due to uneven stress on the diaphragm in the short axis direction.

[0034] Please refer to figure 1 , the invention provides a method for preparing a loudspeaker diaphragm, comprising the following steps:

[0035] Step S1, adding mica and graphene powder into the pulp and stirring evenly to form a pulp-mica-graphene mixture.

[0036] Step S2, pouring the pulp-mica-graphene mixture prepared in step S1 into a diaphragm mold to cool, and pressing it with high pressure to form a loudspeaker diaphragm.

[0037] Specifically, the Young's modulus E of mica is larger than that of pulp. Adding mica to pulp can change the rigidity of the speaker diaphragm, without generating or reducing split vibration, and reducing distortion; after adding mica, the resistance of the speaker diaphragm can be improved...

Embodiment 1

[0045] Add 10g of flaky mica and 1g of graphene powder to 100g of pulp, and stir for 30min until the flaky mica, graphene powder and pulp are evenly mixed. The uniformly mixed pulp-mica-graphene mixture is injected into the diaphragm mold to cool, and high pressure is applied to the diaphragm mold through multiple directions to form a loudspeaker diaphragm in the diaphragm mold.

Embodiment 2

[0047] Add 12g of mica flakes and 2g of graphene powder into 100g of pulp, and stir for 30 minutes until the mica flakes, graphene powder and pulp are evenly mixed. The uniformly mixed pulp-mica-graphene mixture is injected into the diaphragm mold to cool, and high pressure is applied to the diaphragm mold through multiple directions to form a loudspeaker diaphragm in the diaphragm mold.

Abstract

The invention provides a preparation method of a loudspeaker diaphragm, which comprises the following steps: step 1, adding mica and graphene powder into paper pulp, and uniformly stirring the mica, graphene powde, and the paper pulp to form a paper pulp-mica-graphene mixture; and 2, injecting the paper pulp-mica-graphene mixture prepared in the step 1 into a vibrating diaphragm mold for cooling,and performing high-pressure pressing to form the loudspeaker vibrating diaphragm. According to the loudspeaker diaphragm and the loudspeaker monomer, the flaky mica is added into the paper pulp, so that the rigidity of the loudspeaker diaphragm can be changed, the segmentation vibration is not generated or reduced, and the distortion is reduced. After the scaly mica is added, the internal dampingof the loudspeaker diaphragm is large, mechanical energy can be converted into heat energy, the segmentation vibration of the loudspeaker diaphragm is inhibited, and the efficiency of the loudspeakerdiaphragm is greatly improved. Moreover, the graphene particles are very small, so that gaps among paper pulp molecules can be effectively filled, the manufactured loudspeaker diaphragm is tighter, and the strength is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of loudspeaker production, in particular to a method for preparing a loudspeaker diaphragm, a loudspeaker diaphragm and a loudspeaker unit. Background technique [0002] Due to the simple structure and low cost of paper cone speakers, most speakers in the industry currently use paper cones as raw materials. However, TVs are ultra-thin and ultra-narrow, so only oval-shaped and track-shaped small paper cones can be used on TV sets, and the vibrating membrane in the short-axis direction of oval-shaped and track-shaped small paper cones is not uniformly stressed, has large distortion, and is easy to deform. . [0003] In view of the above defects, it is necessary to provide a new method for preparing a loudspeaker diaphragm, a loudspeaker diaphragm and a loudspeaker monomer. Contents of the invention [0004] The main purpose of the present invention is to provide a method for preparing a loudspeaker diaphra...
