The yoke ferromagnetic member 30 and the housing 21 are fixed by welding or bonding, and the coil 33 and the housing 21 are fixed by an adhesive. Referring to fig. 11 to 14, the jaw ferromagnetic member assembly 30 includes a jaw iron 34, a first magnet 31, and a second magnet 32. The jaw 34 has a mouth-shaped configuration with a through hole 340. The blade 34 is made of a highly magnetic conductive material and achieves the optimum magnetic conductivity by magnetic annealing, and may be an integrally formed single part or may be formed by connecting a plurality of parts. The first and second magnetic bodies 31 and 32 are plate-shaped permanent magnets, both of which are disposed in the through-holes 340 and are connected to the inner surface of the blade 34, for example, by welding or adhesive bonding. The first magnet 31 and the second magnet 32 are disposed in parallel and opposite to each other, and the polarities of the magnetic poles of the first magnet and the second magnet are opposite to each other.

Thus, the connection between the fixing portion 10 and the flange ferromagnetic member 30 is more secure, which is advantageous for reducing the twisting and side swinging of the receiver spring 1 when the moving portion 110 vibrates.

The fins 13 are preferably connected to the coil 33 by an adhesive, and a second glue 36 is formed between the fins 13 and the coil 33, refer to fig. 14 to 17, in which the spring plate 1 in fig. 14 and 15 has the spacing slots 14, and the spring plate 1 in fig. 16 and 17 has the fins 13 attached to the side 11a of the moving plate 11. The fins 13 are arranged on the outer side of the coil 33, the coil 33 is partially positioned in the spacing grooves 14, and the spacing grooves 14 can play a certain limiting role. Simultaneously, the fin 13 is located the coil 33 outside, can conveniently scribble the binder between the surface of fin 13 and coil 33, is convenient for realize automatic equipment, improves production efficiency.

As described above, the wing 13 may be located on the same horizontal plane as the moving blade 11, or may be inclined with respect to the moving blade 11. As shown in fig. 15, in the case that the wing pieces 13 are positioned outside the moving piece 11, the inclined arrangement of the wing pieces 13 with respect to the moving piece 11 toward the direction in which the fixing piece 10 is positioned may allow the first glue 35 and the second glue 36 to be connected to each other, thereby enhancing the firmness of the connection.

It will be appreciated that the tab 13 may be attached to the housing component 2 in addition to the coil 33, for example by adhesive to the inner side wall 210 or inner bottom surface 211 of the housing 21. In some embodiments, referring to fig. 18, the connection between the tab 13 and the coil 33 is connected to the housing 21 by an adhesive, and the adhesive used for connecting the tab 13 and the coil 33 and the adhesive used for connecting the tab 13 and the housing 21 are connected to each other to form a second glue body 36, so that the second glue body 36 connects the tab 13, the coil 33 and the housing 21 together at the same time, thereby enhancing the firmness of the connection.

Because the fixed connection of the fins 13 and the coil 33 or the housing assembly 2 enhances the fixing performance of the root 111 and the bent piece 12, the adverse effects caused by twisting and side swinging generated in the working process of the receiver reed 1 can be effectively reduced or even eliminated.
