Problems solved by technology

[0004] For traditional loudspeakers, the sound cone generally uses paper as the sound cone. Due to some characteristics and shortcomings of paper, it brings inherent characteristics and shortcomings to the speaker. For example, paper has the advantages of large internal damping and low density, but it also has elastic modulus The small disadvantage is that the paper cone causes sound coloration when it vibrates, causing the sound to be muddy in a specific frequency band, and the sound quality is degraded. At the same time, the expansion of high frequency is severely limited.

preparation example Construction

[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...

Abstract

The invention provides a preparation method of a loudspeaker cone, a loudspeaker cone and a loudspeaker. The preparation method includes: performing a beating process to obtain pulp; performing a pulp extraction process to obtain an initial sound cone; baking and curing the initial sound cone to obtain the speaker cone; wherein, in the speaker Molecular sieves are added in the preparation process of the sound cone to improve the rigidity of the sound cone of the speaker. After the speaker cone is mixed with molecular sieve, the Young's modulus of the pulp is enhanced, and the existing high internal resistance of the pulp can effectively solve the problem of sound coloring, making the sound sound cleaner and more natural, and also broadening the high frequency.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a method for preparing a loudspeaker cone, a loudspeaker cone and a loudspeaker. Background technique [0002] A loudspeaker is a transducer device that converts electrical signals into acoustic signals. When different electronic energies are transmitted to the voice coil, the voice coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the cone to vibrate. Because the electronic energy changes at any time, the speaker will move forward or backward, so the speaker's The cone will move accordingly, and these actions will change the density of the air to produce sound. [0003] As a sounding structure, loudspeakers are widely used in structures such as mobile phones, televisions, or sound boxes. However, with the improvement of people's living standards, there are higher and higher requirements for the functional quality of l...
