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

[0043] In order to solve the above-mentioned technical problems existing at present, the present invention provides a kind of preparation method of loudspeaker cone, this method comprises:

[0044] performing a beating process to obtain pulp;

[0045] Execute the pulping process to obtain the initial sound cone;

[0046] Baking and curing the initial cone to obtain the speaker cone;

[0047] Wherein, the rigid regulating substance is added in the process of preparing the loudspeaker cone.

[0048]The loudspeaker cone of the present invention has a good Young's modulus and a lower density after the rigidity regulating substance is added, and the density of the rigidity regulating substance mixed into the pulp can be adjusted according to performance requirements to achieve a higher Young's modulus volume, for lighter density purposes. After the rigidity adjustment substance is added, the Young's modulus of the pulp is enhanced, and the existing high internal resistance of th...

Embodiment 1

[0050] Refer below Figure 1 to Figure 5 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.

[0051] In one embodiment of the present invention, step S1 is first performed: performing a beating process to obtain pulp.

[0052] In this step, some specific properties ...

Embodiment 2

[0095] The present invention also provides a loudspeaker cone, which can be prepared by the method in Embodiment 1.

[0096] The loudspeaker cone includes: a sound cone main body, which is used to emit sound through the vibration of the sound basin main body, and the sound basin main body contains a rigid adjustment material to improve the rigidity of the loudspeaker cone.

[0097] Among them, the selection of the rigid adjustment material is not arbitrary, and the rigid adjustment material needs to have greater rigidity than the paper cone, and has a relatively small density, so that the loudspeaker cone with the rigid adjustment material can achieve a higher Young's modulus, for lighter density purposes. To effectively solve the problem of insufficient Young's modulus of the paper cone speaker, the sound quality of the speaker is improved, and it sounds more self-heating and clear; at the same time, the breadth of high frequency is widened, and the sound performance is more ...

Abstract

The invention provides a loudspeaker cone, a preparation method thereof, and a loudspeaker. The preparation method includes: performing a beating process to obtain pulp; performing a pulping process to obtain an initial sound cone; baking and curing the initial sound cone to obtain the speaker cone; wherein, in preparing the A rigid adjustment substance is added to the sound cone of the loudspeaker, and the rigidity adjustment substance includes at least one of magnesium-lithium alloy and silicon carbide. After the rigidity adjusting substance is added, the Young's modulus of the pulp is enhanced, coupled with the existing high internal resistance of the pulp, it can effectively solve the problem of sound coloration, making the sound clearer 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 loudspeaker cone, a preparation method thereof, 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 loudspeakers....
