The invention discloses a voice coil diaphragm integrated structure and a manufacturing method thereof. The voice coil diaphragm integrated structure includes a main body and a ball top; the main body includes an annular diaphragm part and a cylindrical voice coil part; the ball top It is fixed on the outer surface of the annular diaphragm part and covers the outer end opening of the cylindrical voice coil part. In this way, a cylindrical voice coil is integrally extended inward from the inner ring edge of the inner surface of the annular diaphragm part, and the outer surface of the annular diaphragm part is etched to form a first lead-out line, and the inner part of the annular diaphragm part The surface is etched to form the second lead-out line, the inner surface of the cylindrical voice coil part is etched to form the first voice coil line, and the outer surface of the cylindrical voice coil part is etched to form the second voice coil line; instead of the traditional split assembly method, The invention enables the voice coil and the vibrating membrane to be firmly combined without detachment, effectively guarantees product quality, and at the same time greatly reduces the difficulty of assembling the product, which is beneficial to improving the production efficiency of the product.
Description
technical field [0001] The invention relates to the technology in the field of acoustic components, in particular to a voice coil diaphragm integrated structure and a manufacturing method thereof. Background technique [0002] The 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, the cylindrical voice coil is first wound with enameled wire, and then Paste and fix the voice coil on the prefabricated 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 area in contact with the diaphragm is small, and it is difficult to achieve a stable assembly and connection of the voice coil and the diaphragm. After assembly, it will fall off, which will seriously affect the assembly quality of the product. At t...
