Abstract

The invention discloses a voice coil diaphragm integrated structure and a manufacturing method thereof. The voice coil diaphragm integrated structure comprises a main body and a spherical top, wherein the main body comprises an annular diaphragm part and a tubular voice coil part; and the spherical top is fixed on the outer surface of the annular diaphragm part and covers the outer end opening of the tubular voice coil part. The inner annular edge of the inner surface of the annular diaphragm part integratedly extends inwardly to form the tubular voice coil, a first leading line formed and etched on the outer surface of the annular diaphragm part is matched, a second leading line is formed and etched on the inner surface of the annular diaphragm part, a first voice coil line is etched and formed on the inner surface of the tubular voice coil part, and a second voice coil line is etched and formed on the outer surface of the tubular voice coil part. A traditional split assembly mode is replaced, the voice coil and the diaphragm are firmly combined together, a break-off phenomenon does not happen, the quality of the product can be effectively ensured, the assembly difficulty of the product is greatly reduced, and the production efficiency of the product is improved.

Description

technical field [0001] The invention relates to the technology in the field of acoustic elements, in particular to an integrated structure of a voice coil diaphragm and a manufacturing method thereof. Background technique [0002] Voice coil and diaphragm are two important components in various acoustic equipment such as speakers and microphones. These two components are usually split. During production, enameled wire is first used to make a cylindrical voice coil, and then Paste the voice coil on the pre-fabricated diaphragm. [0003] Although the above structure can realize the production and assembly of the voice coil and the diaphragm, however, due to the small diameter of the enameled wire used in the voice coil, the contact area with the diaphragm is small, and it is difficult to realize the stable assembly and connection of the voice coil and the diaphragm. After assembly, there will be a phenomenon of falling off, which seriously affects the assembly quality of the ...
