Multipoint excitation source loudspeaker clamp

Abstract

The invention relates to a multipoint excitation source loudspeaker clamp. The multipoint excitation source loudspeaker clamp is characterized by comprising an upper die and a lower die, wherein the four corners of the lower surface of the upper die are respectively provided with four convex feet which are symmetric to each other along a long shaft and a short shaft, the upper die is provided with at least two voice coil brackets which are distributed along the long shaft direction, and the four corners of the upper surface of the lower die are respectively provided with four concave stations which are symmetric to each other along the long shaft and the short shaft; when the upper die is matched and combined with the lower die, the four concave stations are matched with the four convex feet of the upper die correspondingly; and the lower die is provided with a voice basin groove for loading a voice basin and a locating support sheet, and the shape of the voice basin groove is matched with the shapes of the voice basin and the locating support sheet. With the adoption of the multipoint excitation source loudspeaker clamp, as the structure is ingenious and reasonable, the voice basin, the locating support sheet and voice coils can be loaded so as to be accurately located by virtue of the clamp, gluing equipment can be used for conveniently coating glue at an appointed position of each part, and the production efficiency and the finished product qualified rate are greatly improved.

Description

technical field [0001] The invention relates to a loudspeaker assembly jig, in particular to a multi-point excitation source loudspeaker jig for assembling a sound cone, a positioning support piece and a voice coil component of a multi-point excitation source loudspeaker unit, belonging to the field of electroacoustic technology. Background technique [0002] In the prior art, for speaker products used in high-end ultra-thin LED LCD TVs, thin multi-point excitation source speaker units or systems are generally used to obtain wider frequency response bandwidth and better sound quality. For example, a Chinese patent with the application number "200910035698.X" and the name "dual driver speaker" has been widely cited on high-end ultra-thin TV sets. However, due to the complex assembly process of such thin and narrow loudspeakers, the assembly between components (especially the gluing and curing between the voice coil and the positioning support piece, and the film-type sound co...

AI Technical Summary

Problems solved by technology

However, due to the complex assembly process of such thin and narrow loudspeakers, the assembly between components (especially the gluing and curing between the voice coil and the positioning support piece, and the film-type sound cone) is relatively difficult. If If you do not rely on fixtures but only rely on operators to operate with bare hands, it will not only seriously affect the assembly efficiency of the product, but also cause a high defect rate of the finished product, which is specifically reflected in the deflection of the position of the voice coil on the sound cone and the positioning support. Finally, when the speaker is working, the voice coil is easy to touch the outer wall of the magnet, the outer wall of the magnetic pole core or the inner wall of the U iron when it moves in the magnetic gap, resulting in poor sound of the speaker

Moreover, because this type of multi-point excitation source speaker has at least two or more voice coil components and a corresponding number of magnetic circuit systems, the cost is expensive, and a bad position of a voice coil may cause the entire speaker to be scrapped, and the cost is extremely high.
