Abstract

The invention discloses a magnetic conduction structure and a sounding device, comprising a first part and a second part, the first part and the second part are formed respectively, the second part is fixed on the first part, The first part is used to carry a permanent magnet, the first part and the second part are both magnetically permeable materials, and the second part is configured to form a magnetic gap with the permanent magnet. A technical effect of the present invention is that by dividing the magnetic permeable structure into the first part and the second part to form separately, the structure of the part is simple, and the part can be made with a simple processing technology to improve the processing accuracy.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, and more specifically, to a magnetically conductive structure and a sound generating device. Background technique [0002] The loudspeaker is a very commonly used electrical transducer device, which is often used in electronic and electrical equipment that emits sound, and emits sound by converting electrical signals into acoustic signals. Loudspeakers have a wide range of applications and are of various types. Therefore, the efficiency and quality of production affects the cost of production and the quality of the loudspeaker. [0003] The magnetic structure in the loudspeaker is an important part of the loudspeaker. The existing production methods are stamping and cold heading / cold forging processes and then processed and formed. The manufacturing process of these two processes is complicated, the cost is high, and the requirements for unprocessed materials are relatively h...
