Description

Technical Field

[0001] The utility model relates to the technical field of processing jigs, in particular to a positioning jig for a flat diaphragm speaker diaphragm structure. Background Technique

[0002] The flat diaphragm speaker diaphragm is an important part of a speaker. The voice coil wire is composed of a very thin metal conductor and is flat on the plane of the vibrating diaphragm. The magnetic circuit part is a parallel magnet distributed on one side or both sides of the flat diaphragm. For the convenience of assembly, its dome diaphragm and voice coil are often bonded together to form a component, which we call the speaker diaphragm.

[0003] When processing and bonding the speaker diaphragm, it is necessary to clamp and align the dome diaphragm and the voice coil. Traditionally, it is manually clamped and then subsequent processing work is carried out, which will affect the convenience of the operator's processing to a certain extent and the efficiency is low. Therefore, a fixture is used to position and clamp the flat diaphragm speaker diaphragm during the current flat diaphragm speaker diaphragm processing and positioning.

[0004] However, the flat diaphragm speaker diaphragm components are small and not convenient to fix, and the accuracy during processing is insufficient. The convenience of designing these jigs for each assembly stage of the flat diaphragm speaker diaphragm components is not high enough, which leads to a reduction in the convenience of processing the flat diaphragm speaker diaphragm components, thus affecting the processing effect of the flat diaphragm speaker diaphragm.
