Magnetic attraction joint, magnetic attraction joint component and bone conduction speaking device

Abstract

The application discloses a magnetic attraction joint, a magnetic attraction joint component and a bone conduction speaking device. The magnetic attraction joint includes a magnetic adsorption ring. Afirst terminal and a second terminal are disposed in the magnetic adsorption ring, and respectively have a first contact surface and a second contact surface which are visible from an outer end surface of the magnetic adsorption ring. The magnetic adsorption ring is divided into at least two ring segments in a circumferential direction. Outer end surfaces of the adjacently disposed ring segmentshave different magnetic polarities. Through the above manner, the joint can improve accuracy and efficiency of butt-joint connection, and facilitate user use.

Description

technical field [0001] The present application relates to the field of magnetic suction technology, in particular to a magnetic suction joint, a magnetic joint assembly 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 increasingly 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...

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
