Abstract

The invention provides a magnetic driving mechanism and a receiver comprising the same. The magnetic driving mechanism comprises a U-shaped balance armature, a lower shell and a middle-layer partition board; one end of the U-shaped balance armature is fixedly connected with the bottom of the lower shell, and the other end of the U-shaped balance armature is located in a first hollow cavity enclosed by the middle-layer partition board and the lower shell in a suspended manner; and the lower shell and the middle-layer partition board are used for providing a magnetic flux path. The magnetic driving mechanism and the receiver comprising the same of the invention have the advantages of simple structure, small size and the like.

Description

technical field [0001] The invention relates to the technical field of micro-device design, in particular to a magnetic drive mechanism and a receiver including the magnetic drive mechanism. Background technique [0002] Receivers are widely used in portable electronic devices such as mobile phones, laptops, and hearing aids. With the rapid development of these portable electronic devices, people's functional requirements for them are also getting stronger and stronger, and the receivers applied to them are also developing correspondingly and rapidly. [0003] U-shaped magnetic drive mechanism is widely used in general receivers. Its working principle is: using the basic principle of electromagnetic conversion, when working, the AC current signal passes through the magnetic induction coil, and the coil induces magnetism, which is opposite to the U-shaped balanced armature placed in the middle of the coil. Magnetized (polarized), the U-shaped balance armature that is magneti...
