[0024] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0025] Embodiment 1

[0026] As Figures 1 to 2 shown, a magnetic circuit connector with enhanced magnetism includes:

[0027] A magnetic conduction base 2, which includes a base 21, a middle support base 22, an arc connecting base 23 and a side abutting base 24. The middle support base 22 is located on the upper end surface of the base 21. A pair of arc connecting bases 23 are located on the opposite sides of the base 21. The side abutting base 24 is located on the upper end surface of the arc connecting base 23; A Halbach array magnet 1 is installed on the magnetic conduction base 2, which includes a magnet with a vertical magnetic pole 11 and a magnet with a horizontal magnetic pole 12. A pair of magnets with horizontal magnetic poles 12 are located on the opposite sides of the magnet with a vertical magnetic pole 11. The S pole of the magnet with a vertical magnetic pole 11 abuts on the middle support base 22. The S poles of a pair of magnets with horizontal magnetic poles 12 both abut on the side abutting base 24, and neither of them abuts on the arc connecting base 23, forming a gap 20 in the area above the arc connecting base. The arc connecting base 23 is a quarter-ring structure, and the magnetic force transmission path is optimal in an arc close to a perfect circle.

[0028] In this embodiment, the S pole is connected to the magnetic conduction base. If 3 N poles are connected to the magnetic conduction base, it also has the same magnetic enhancement effect and is also within the protection scope of this patent.

[0029] The magnetic conduction base 2 is made of FeCoV material. Selecting FeCoV material as the magnetic conduction base, it has excellent magnetic conduction performance and a relatively high magnetic induction intensity.

[0030] The magnetic conduction base 2 is an integrally formed structure and can also be formed by an assembled form.

[0031] The magnet with a vertical magnetic pole 11 and the magnet with a horizontal magnetic pole 12 have the same regular cube structure.

[0032] The height of the side abutting base 24 is equal to the height of the magnet with a horizontal magnetic pole 12.

[0033] The side lengths of the magnet with a vertical magnetic pole 11 and the magnet with a horizontal magnetic pole 12 are both 4 mm. Through miniaturization design, it can be applied to various types of products such as speakers.

[0034] Example 2

[0035] As Figures 1 to 5 shown, compared with Example 1, the magnetic circuit connector in this example further includes an additional structure, which includes a pair of horizontally placed magnets 12 with opposite poles, a pair of arc-shaped connecting seats 23, and a pair of side abutting seats 24. The pair of arc-shaped connecting seats 23 are located on opposite sides of the base 21, the pair of side abutting seats 24 are respectively located on the upper end faces of the pair of arc-shaped connecting seats 23, the pair of horizontally placed magnets 12 with opposite poles are located on opposite sides of the vertically placed magnet 11 with opposite poles, and the S poles of both are abutted on the side abutting seats 24; on the basis of Example 1, by adding an additional mechanism, the magnetic conduction base is formed into a structure similar to a lotus flower, and the Halbach array magnet forms a cross-shaped structure, sharing the same vertically placed magnet with opposite poles. After installation and molding, it has a better three-dimensional structure and more excellent magnetic conduction performance and magnetic attraction force.

[0036] In the present invention, the base on the magnetic conduction base can be formed into a regular polyhedron with an even number of sides, and the vertically placed magnet with opposite poles has the same structure. The vertically placed magnet with opposite poles and the horizontally placed magnet with opposite poles are installed on the magnetic conduction base through the installation methods of Example 1 and Example 2.

[0037] Application Example

[0038] Select a conventional magnet (Comparative Example 1), a Halbach array magnet (Comparative Example 2), a Halbach array magnet with a conventional base 3 added (Comparative Example 3, as Figure 6 shown), and Example 1 of the present invention, and make them act on the object to be magnetically attracted 100 (made of iron-cobalt-vanadium material). The magnetic attraction performance of Comparative Examples 1-3 and Example 1 is tested. The test results are shown in the following table.

[0039] Table of magnetic attraction results of Comparative Examples 1-3 and Example 1

[0040]

[0041] Among them, X is the magnetic attraction distance; the length * width * height of Comparative Example 1 = 12 mm * 4 mm * 4 mm; the length * width * height of a single magnet in Comparative Example 2 = 4 mm * 4 mm * 4 mm; the length * width * height of a single magnet in Comparative Example 3 = 4 mm * 4 mm * 4 mm; the length * width * height of the magnet in Example 1 = 4 mm * 4 mm * 4 mm.

[0042] When the distance between the magnet assembly and the target object is 0 mm, the magnetic attraction force of Comparative Example 2 is about 1.75 times that of Comparative Example 1, and the magnetic attraction force of Example 1 is enhanced to 1.24 times that of Comparative Example 2; as the test distance X increases, the magnetic attraction force gradually decreases, but the magnetic attraction force of Example 1 is still greater than that of Comparative Example 2 and Comparative Example 3. Therefore, this magnetic circuit connector has an excellent magnetic enhancement effect.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or additions to the described specific embodiments or use similar means for substitution, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
