Description

Technical Field

[0001] The utility model relates to the technical field of back plate electret charge polarization, in particular to a continuous transmission structure for back plate electret charge polarization. Background Art

[0002] Microphone products are widely used in electronic products such as headphones, conference systems, mobile phones, computers, etc. As consumer groups have higher and higher requirements for sound, electret microphones and back plates as their main accessories have emerged. The main manufacturing process is to composite FEP film after surface treatment of metal substrate (generally nickel plating). The metal substrate serves as a conductor and the film serves as an insulating layer with dielectric properties. The electret charge on the film, the consistency and stability of the electret charge will have an important influence on the sensitivity of the microphone sound. The stability of the electret charge of the back plate determines the stability of the microphone in subsequent use. If the electret charge stability of the back plate in the microphone is poor, the initial sensitivity of the produced microphone may not be a problem, but as time goes by, the electret charge on the surface of the back plate gradually decays, and the sensitivity of the microphone also decreases until the function fails.

[0003] Existing backplates require a polarizer body when performing electret charge polarization. When the backplate carrier plate is polarized within the polarizer body, the carrier plate is simultaneously heated. After polarization is complete, it is inconvenient for workers to remove the hot carrier plate, which can easily cause burns. Therefore, the present invention provides a continuous transmission structure for electret charge polarization of backplates to address the aforementioned issues. Utility Model Content

[0004] The purpose of the present invention is to provide a continuous transmission structure for the electret charge polarization of a back plate, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A continuous transmission structure for the polarization of the electret charge of a back plate includes a polarizer body, a cooling mechanism and an installation mechanism. The right end of the polarizer body is provided with a connecting frame symmetrically arranged front to back through the installation mechanism, and fixing cylinders are symmetrically arranged left to right between the connecting frames. A cooling mechanism is provided between the two connecting frames, and a limiting mechanism is provided at the upper end of the connecting frame.

A fixing frame is provided at the upper end of the connecting frame corresponding to the connecting plate. The setting of the limiting plate facilitates limiting the load-bearing plate to prevent the load-bearing plate from offsetting or falling during movement.
