Magnetic attracting joint and bone conduction loudspeaker device

Abstract

The invention discloses a magnetic attracting joint and a bone conduction loudspeaker device. The magnetic attracting joint comprises a magnetic adsorption ring, a first terminal and a second terminal; wherein an outer end surface of the magnetic adsorption ring is rotationally symmetric with respect to a predetermined symmetry point; the first terminal and the second terminal are arranged in themagnetic adsorption ring, and have a first contact surface and a second contact surface separately visible from the outer end surface of the magnetic adsorption ring; wherein the first contact surfaceand the second contact surface are arranged such that the first contact surface and the second contact surface before rotation separately overlap at least partially with the first contact surface andthe second contact surface after rotation when the magnetic adsorption ring is symmetrically rotated. In the above manner, the invention can improve the accuracy of docking with the corresponding joint, which is convenient for assembly and use.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a magnetic joint and a bone conduction speaker device. Background technique [0002] With the development of science and technology, the charging method of electronic equipment is constantly changing. In order to adapt to the change of charging method, the structure of the corresponding power interface is also constantly undergoing adaptive changes. [0003] As a form of power interface, the magnetic power interface is more and more used in various electronic devices, such as bone conduction speaker devices such as bone conduction MP3 and bone conduction earphones. Since the power supply includes a positive terminal and a negative terminal, when the electronic device is charged, if the positive terminal and the negative terminal of the charging interface of the electronic device cannot be aligned with the positive terminal and the negative terminal of the charging inte...

AI Technical Summary

Problems solved by technology

Since the power supply includes a positive terminal and a negative terminal, when the electronic device is charged, if the positive terminal and the negative terminal of the charging interface of the electronic device cannot be aligned with the positive terminal and the negative terminal of the charging interface of the charger, it will not be able to Establish a good electrical connection relationship, thereby reducing the charging efficiency of electronic equipment; moreover, there is usually only one alignment method between the positive and negative terminals of the charging interface of electronic equipment and the positive and negative terminals of the charging interface of the charger, and at the same time during the production process There is only one relative positional relationship between the magnetic attraction structure and the positive terminal and negative terminal in the power interface, which brings inconvenience to users and production assembly
