Description

Technical Field

[0001] The present invention relates to the technical field of loudspeaker cones, and in particular to a multi-plane layer three-dimensional multi-directional reinforced cone and a manufacturing method thereof. Background Art

[0002] As a device that can convert electrical energy into sound energy, the speaker is widely used in mobile terminals such as mobile phones, computers, PADs, etc. The performance of the speaker directly affects the sound amplification effect of each terminal device that cooperates with it. The speaker structure includes a magnetic circuit system and a vibration system, wherein the vibration system includes a sound basin and a voice coil. After receiving the current signal from the external circuit, the voice coil will reciprocate under the action of the electromagnetic field to cut the magnetic lines of force, drive the sound basin to vibrate, and then radiate sound waves to the outside world, thereby completing the conversion of electrical energy to sound energy. From the above description, it can be seen that the sound basin is one of the key components of the speaker's vibration sound generation, especially the strength of the sound basin. The existing method of increasing the strength of the sound basin is to increase the strength by increasing the thickness. At the same time, increasing the thickness will increase the weight of the sound basin, which will greatly deteriorate the transient response, intermodulation distortion, harmonic distortion, efficiency, etc. of the speaker, and the sound quality cannot be improved. There is also the addition of reinforcing ribs. The existing reinforcing rib methods are all unidirectional, which only enhances the strength in one direction; unidirectional reinforcement cannot be well applied to the flat sound basin to greatly improve the performance of the flat sound basin.

[0003] The present invention is to solve the above-mentioned deficiencies and provides a multi-plane layer three-dimensional multi-directional reinforced sound cone and a manufacturing method thereof.

[0004] The above-mentioned object of the present invention is achieved through the following technical scheme: a multi-planar three-dimensional multi-directional reinforced sound basin, the sound basin is composed of a plurality of planar layers stacked up and down, the planar layers are a repeated folding structure, the cross-section of the planar layers is a toothed structure, and the toothed structures between adjacent planar layers are arranged in parallel and staggered in different directions.

[0005] Furthermore, the cross section of the plane layer is a tooth-like structure with isosceles triangles arranged in parallel.

[0006] Furthermore, the cross section of the plane layer is a tooth-like structure with isosceles trapezoids arranged in parallel.

[0007] Furthermore, the cross section of the planar layer is a tooth-like structure with circular arcs arranged in parallel.

[0009] Furthermore, an unfolded flat layer is provided between the two adjacent bonded flat layers.

[0010] Furthermore, the upper surface and the lower surface of the multi-plane layer after bonding are respectively bonded to an unfolded flat layer.

[0011] A method for manufacturing a three-dimensional, multi-directionally reinforced sound basin with multiple plane layers. A special mold is provided with overlapping folded tooth surfaces on the upper and lower mold surfaces, and a positioning device is provided between the upper and lower molds to ensure that the concave and convex of the tooth surfaces accurately correspond each time the upper and lower molds overlap and press. The sound basin material is placed in a heater to make the material temperature reach 80-90 degrees, maintained for 30-60 seconds, and then placed between the upper and lower molds for pressing and forming; the two pressed and formed plane layers are staggered and bonded.

[0012] Furthermore, a fixing tenon of a corresponding shape is installed on the pressed plane layer, and then an unfolded plane layer is arranged between adjacent plane layers and on the upper and lower surfaces of the multiple plane layers after bonding, and finally bonding is performed.

[0013] The multi-plane layer three-dimensional multi-directional reinforced sound cone and the manufacturing method thereof of the present invention break through the original one-way reinforcement structure and are improved into a three-dimensional multi-directional reinforcement, which effectively improves the distortion defect of the speaker and improves the vibration intensity of the sound cone. The folded reinforcement structure not only increases the rigidity of the diaphragm, but also maintains the low weight requirement of the diaphragm, and has low production cost and simple manufacturing process.
