Detailed description of the invention
For further appreciating that content of the present utility model, in conjunction with the accompanying drawings and embodiments this utility model is described in detail.
Embodiment 1
Shown in Fig. 1, a kind of moving-iron type vibrator of the present embodiment, including square iron 1, Magnet 2, coil 3 and balanced armature
4, the cross sectional shape of square iron 1 is straight-flanked ring, has magnetic conduction effect, and the inwall up and down of square iron 1 is respectively provided with a Magnet 2, should
Magnet 2 is made up of permanent magnet, and coil 3 is fixed on one end of square iron 1, Magnet 2 and coil 3 and all uses glue to be bonded in square iron
On 1, balanced armature 4 is " u "-shaped structure, and one end of balanced armature 4 is fixed on square iron 1, specifically can use and be welded to connect,
The other end sequentially passes through coil 3 and the center of upper and lower two blocks of Magnet 2, and as the vibration impact hammer of vibrator, square iron 1 is vibration
The fixing end of device.After being passed through alternating current in coil 3, the induced field that coil 3 produces changes the fixed magnetic field of Magnet 2,
So that balanced armature 4 along with curent change in magnetic field power by different directions, owing to square iron 1 is fixed,
