[0049] In order to solve the above-mentioned technical problems existing at present, the present invention provides a kind of preparation method of loudspeaker cone, described method comprises:
[0050] performing a beating process to obtain pulp;
[0051] Execute the pulping process to obtain the initial sound cone;
[0052] Baking and curing the initial cone to obtain the speaker cone;
[0053] Wherein, the molecular sieve is added in the preparation process of the loudspeaker cone.
[0054] After the speaker cone of the present invention is added with molecular sieves, the density has little effect, and its Young's modulus is greatly improved. Under the condition of ensuring the light density and high internal resistance of the paper cone, its stiffness is greatly improved, and the sound quality is at a higher level. improvement. After being mixed with molecular sieves, the Young's modulus of the pulp is enhanced, coupled with the existing high internal resistance of the p...
Embodiment 1
[0056] Refer below Figure 1 to Figure 4 The preparation method of the loudspeaker cone of the present invention is explained and illustrated, wherein, figure 1 A schematic flow diagram showing a method for preparing a loudspeaker cone in an embodiment of the present invention; figure 2 A schematic block diagram showing a method for preparing a loudspeaker cone in an embodiment of the present invention; image 3 A schematic block diagram showing a method for preparing a loudspeaker cone in another embodiment of the present invention; Figure 4 A schematic block diagram showing a method for preparing a loudspeaker cone in yet another embodiment of the present invention; Figure 5 A schematic block diagram showing a method for preparing a loudspeaker cone in another embodiment of the present invention.
[0057] In one embodiment of the present invention, step S1 is first performed: performing a beating process to obtain pulp.
[0058] In this step, some specific properties ...
Embodiment 2
[0102] The present invention also provides a loudspeaker cone, and the loudspeaker cone includes:
[0103] The main body of the sound cone is used to emit sound through the vibration of the main body of the sound cone. The main body of the sound cone contains molecular sieves to improve the rigidity of the sound cone of the speaker.
[0104] Optionally, molecular sieves are uniformly doped in the cone body; or
[0105] The molecular sieve coating is secured to the outer surface of the cone body by an adhesive covering on the outer layer of the molecular sieve; or
[0106] The sound cone body includes a first sound cone body and a second sound cone body combined with each other, wherein a molecular sieve is arranged between the first sound cone body and the second sound cone body to obtain a paper sound cone-molecular sieve- Sandwich structure of paper sound cone.
[0107] Among them, the choice of molecular sieve is not arbitrary, and the rigidity adjustment requires greater...
