Technical scheme of the present invention is as follows: a kind of linear vibration electric motor, it comprises spring part, the oscillator that is connected with spring part and the pedestal of accommodating described spring part and oscillator, described spring part is provided with the fixed part that is connected with oscillator, along the extended elasticity arm of fixed part and extended and be engaged in the junction surface of pedestal along elasticity arm, described junction surface is provided with first surface and the second surface relative with first surface near oscillator, described second surface is connected with pedestal, described linear vibration electric motor also comprises the catch that is connected with described junction surface, and described catch places on the first surface.
Preferably, described fixed part comprises the first fixed part and the second fixed part, and described the first fixed part is mutually vertical with the second fixed part.
Preferably, described junction surface is parallel with the second fixed part.
Preferably, the described elasticity arm support sector that is provided with pars intermedia and extends in the same way to described pars intermedia two ends.
Preferably, described support sector is provided with the pattern of hollow out.
Preferably, described pedestal is provided with along the protuberance of the fixed coil of oscillator direction extension.
A kind of manufacture method of linear vibration electric motor may further comprise the steps: pedestal is provided; Wiring board is provided, wiring board is fixed on base bottom; Coil is provided, coil is contained in the spatial accommodation of pedestal and with wiring board and is electrically connected; Catch is provided; Spring part is provided, and described spring part is provided with fixed part, along the extended elasticity arm of fixed part and along the extended junction surface of elasticity arm; Utilize the method for laser spot welding to weld together catch and junction surface, form an integral body; Oscillator is provided; Oscillator is connected with the fixed part of spring part; The method that junction surface and the pedestal of spring part utilized laser spot welding welds together; With loam cake and pedestal winding.
Preferably, provide the spring part of the second fixed part that is provided with the first fixed part and extends along the first fixed part, the first fixed part is connected with two adjacent sides of oscillator respectively with the second fixed part.
Beneficial effect of the present invention is: because the method for first an independent catch and spring part being utilized laser spot welding welds together, form an integral body, will utilize the method for laser spot welding to be welded on the pedestal with the spring part of catch again.Motor oscillator is when motion, and the stress at the junction surface of spring part will be loose by spot welding punishment, thereby the protection solder joint, avoid spot welding on impact and the structural damage of spring part material property, makes motor more reliable when work.
