Detailed description of the invention
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；Should be appreciated that preferred reality
Execute example only for explanation this utility model rather than in order to limit protection domain of the present utility model.
As it is shown in figure 1, a kind of mobile phone linear motor, including upper casing assembly 1, ticker assembly 2 and lower cover assembly
3, described ticker assembly is arranged in the closed cavity of upper casing assembly and the formation of lower cover assembly, and described ticker is arranged
Having magnet steel, described lower cover assembly is provided with coil, coil electricity produces magnetic field, and the magnetic field that magnet steel produces produces with coil
Magnetic field interaction makes ticker vibrate.
First magnetizing magnet steel and produce magnetic field, then apply electric current to coil, coil produces corresponding magnetic field, magnet steel
Produce the magnetic field interaction that produces of magnetic field and coil so that ticker acting on left and right in horizontal direction by spring
Swinging and produce high vibrating effect, this utility model only has only to just can realize vibrating effect to coil electricity at once, significantly contracts
Short response time, and whole device is not provided with oiliness bearing, without abrasion, considerably increases service life.
As in figure 2 it is shown, described upper casing assembly includes the housing being made up of stainless steel material, described housing includes upper casing
11 and 4 sidewalls 12 being downwardly extending along upper casing edge, described upper casing is provided with magnetic liquid adjusting hole 13, tightly
Paste one of them sidewall and be provided with stopping means 14.It is provided with first on a wherein sidewall of remaining 3 sidewall described to step down platform
Rank 15.Two adjacent sidewalls are connected by segmental arc 16
As preferably, casing uses stainless steel material, and surface need not plating just can reach each environmental test requirement；Casing
Using drawing process molding, the fast precision of efficiency is high；
In this utility model, two the magnetic liquid adjusting holes can crossed on upper casing front increase magnetic liquid or minimizing
