Abstract
The utility model discloses an electromagnetic type buzzer which comprises a shell body. A magnetic ring tightly matched with the inner wall of the shell body is arranged inside the shell body, an upper circular groove and a lower circular groove are formed in the magnetic ring, T-shaped iron is fixedly arranged in the upper circular groove and is aligned with the central position of the magnetic ring, a magnet adding sheet and a vibration sheet are fixedly arranged in the lower circular groove and arranged on the bottom of the T-shaped iron, a coil is further arranged on the T-shaped iron in a winding mode, an inserting board with a guide pin is fixedly arranged on the T-shaped iron, epoxy glue is arranged inside a cavity above the inserting board with the guide pin, and 703 glue is connected between the T-shaped iron and the inserting board with the guide pin in an adhesive mode. The electromagnetic type buzzer can use a button board to directly carry out adjustment of a magnetic force clearance on the buzzer, mainly reduces manufacturing procedures, lowers production cost, and is better in electrical insulation property, sealing property and ageing-resistant property.
Description
Technical field
The utility model relates to a kind of hummer, especially a kind of electromagnetic type hummer.
Background technology
China is the big producing country of hummer, has dominated market by feat of proven technique, and the product of certain structures during production, need be adjusted the magnetic circuit gap with handpress in the prior art, T iron and the manual contraposition of magnet ring need, and centrally aligned fully; For avoiding epoxy glue to flow to vibrating reed, causing it can't sound, and needs to make a call between T iron and housing a circle 703 silica gel, could annotate epoxy glue, and manufacturing process is more, and production cost is also high relatively.
The utility model content
The purpose of this utility model is a kind of electromagnetic type hummer that reduces manufacturing process and reduce production costs that designs for the deficiency that solves above-mentioned technology.
The electromagnetic type hummer that the utility model is designed, comprise housing, be provided with in housing and the friction tight magnet ring of inner walls, annular groove and following annular groove fixedly have T iron in last annular groove on magnet ring is provided with, and align with the center of magnet ring, in the following annular groove magnetic sheet of increasing and vibrating reed are arranged fixedly, and be located at the bottom of T iron, on T iron, also be wound with coil, T iron upper fixed has band guide pin plate, is provided with epoxy glue in the chamber above band guide pin plate.
During assembling, T iron and coil are put into the center of magnet ring, the upper fixed band guide pin plate of while T iron, and be placed on together on the button plate by flat, utilize the button plate that the magnetic gap of hummer is adjusted automatically, after adjustment finishes with vibrating reed with to increase magnetic sheet spot-welded together, be placed on the T iron bottom corresponding with magnet ring simultaneously, then the T iron, coil, magnet ring, band guide pin plate, the vibrating reed that assemble are put into housing with increasing magnetic sheet, inject epoxy glue in the chamber above band guide pin plate at last.
In order to make electrical insulation capability, sealing property and ageing-resistant performance better, be bonded with 703 glue between described T iron and the band guide pin plate.
The designed electromagnetic type hummer of the utility model can utilize the button plate directly hummer to be adjusted magnetic gap, has mainly reduced manufacturing process, has reduced production cost, and electrical insulation capability, sealing property and ageing-resistant performance are better.
