Auxiliary magnetic structure of loudspeaker and assembling method of auxiliary magnetic structure

Abstract

Disclosed are an auxiliary magnetic structure of a loudspeaker and an assembling method of the auxiliary magnetic structure. The structure comprises a hollow frame, a lower piece, a primary magnet, an auxiliary magnet, a primary magnet pole piece and an auxiliary magnet piece, wherein the lower piece is arranged at the bottom of the frame, the primary magnet and the auxiliary magnet are arranged on the lower piece, the primary magnetic pole piece is arranged on the primary magnet and an auxiliary magnetic pole piece arranged on the auxiliary magnet. The auxiliary magnetic structure and the assembling method of the auxiliary magnetic structure are applicable to the light and thin loudspeaker and the primary magnet and the auxiliary magnet are convenient to install.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a secondary magnetic structure of the loudspeaker and an assembly method thereof. Background technique [0002] In the prior art, there are two conventional designs for the secondary magnetic structure of the loudspeaker. like figure 1 In the conventional design a shown, the thickness of the speaker is relatively large due to the combination of the auxiliary magnet 2 and the main pole piece 6, which is not suitable for thin and light speakers. [0003] another example figure 2 In a conventional design b shown, the auxiliary magnetic pole 2 and the main magnetic pole 5 are assembled with the lower plate 4 respectively, and then the assembled whole is put into the frame 1, because of the interaction between the main magnetic 5 and the auxiliary magnetic 2. It affects the installation of the main magnet 5 and the auxiliary magnet 2. During assembly, the auxiliary magnet 2 is sucked o...

AI Technical Summary

Problems solved by technology

A conventional design a as shown in Figure 1, Because the auxiliary magnet 2 and the main pole piece 6 are bonded together, the thickness of the speaker is relatively large, and this type of design is not suitable for thin and light speakers

[0003] Another example is Figure 2 shows a conventional design b, the auxiliary magnetic pole 2 and the main magnetic pole 5 are respectively assembled with the lower piece 4, and then the assembled whole is put into the frame 1, because the main magnetic pole 5 and the auxiliary magnetic The interaction between the two affects the installation of the main magnet 5 and the auxiliary magnet 2. During assembly, the auxiliary magnet 2 is sucked off by the main magnet 5. Although it can meet the light and thin loudspeaker, the installation is relatively difficult. Convenient production

[0004]These are general auxiliary magnetic positioning methods. These two existing conventional designs are not completely suitable for thin and light speakers. Therefore, a new The secondary magnetic structure and its assembly method
