Description
[technical field]
The utility model relates to a kind of vibrating motor, relates in particular to a kind of linear vibration electric motor that is used for the flat of portable consumer electronic product.
[background technology]
Along with development of electronic technology, the portable consumer electronic product more and more is subjected to pursuing of people, as mobile phone, handheld device, guider or palm multimedia entertainment equipment etc., generally all can use vibrating motor and do system feedback, such as vibrational feedback of the incoming call prompting of mobile phone, information indicating, navigation hint, game machine etc.Use so widely, just require the performance height of vibrating motor, long service life.
Use at present more and performance preferably vibrating motor be the linear vibration electric motor of flat, the linear vibration electric motor relevant with the utility model mainly comprise the pedestal that is provided with spatial accommodation, be positioned at coil on the pedestal, be connected in the resilient support part of pedestal, be suspended on the oscillator of being made up of balancing weight and permanent magnet of spatial accommodation by elastic supporting member for supporting optical member, coil is positioned at the below centre of permanent magnet, and the two is contained in the spatial accommodation of pedestal in the lump.The end of elastic supporting member for supporting optical member is fixed on the pedestal by laser spot welding, supports the reciprocating motion of the horizontal direction of oscillator when work.From angle of mechanics, oscillator is in the process of motion, and elastic supporting member for supporting optical member stress will occur in the part with pedestal spot welding to be concentrated, and the spot welding meeting produces certain destruction to the material property and the structure of elastic supporting member for supporting optical member in addition, therefore be very easy to produce fracture, motor was lost efficacy.
Therefore, be necessary to provide a kind of novel linear vibration electric motor.
[utility model content]
The purpose of this utility model is to solve the concentrated deficiency of solder joint stress of said structure, and a kind of product linear vibration electric motor more reliably that makes is provided.
The technical solution of the utility model is as follows: a kind of linear vibration electric motor, it comprises spring part, 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 be provided with near the first surface of oscillator and with the first surface opposing second surface, 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 first fixed part and second fixed part, and described first fixed part is vertical mutually with second fixed part.
Preferably, described junction surface is parallel with 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.
The beneficial effects of the utility model are: because earlier the method that an independent catch and spring part are utilized laser spot welding welds together, form an integral body, the spring part that will have catch again utilizes the method for laser spot welding to be welded on the pedestal.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 influence and the structural damage of spot welding to the spring part material property, makes motor more reliable when work.

Fig. 3 is the utility model linear vibration electric motor one embodiment cutaway view.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1 to Figure 3, be the utility model one embodiment linear vibration electric motor, it comprise pedestal 16, with pedestal 16 windings form spatial accommodation loam cake 11, be contained in coil 15 in the spatial accommodation, be connected in pedestal 16 spring part 13, be suspended on oscillator 12 in the spatial accommodation by spring part 13.Vibrating motor also comprises the wiring board 17 that is fixed in pedestal 16 bottoms, and this wiring board 17 is provided with the pad 170 that is electrically connected with coil 15.
In the utility model linear vibration electric motor, also comprise the catch 14 that is connected with the junction surface 132 of spring part 13, described catch 14 can be greater than junction surface 132, also can be less than junction surface 132, also or with junction surface 132 equal and opposite in directions, catch 14 can be for square, also can be circle, also or other shape.Described junction surface 132 be provided with near the first surface of oscillator 12 (indicating) and with first surface opposing second surface (indicating), described catch 14 can arrive with the first surface laser spot welding earlier, form an integral body, spring part 13 laser spot weldings that will have catch 14 again are to the sidewall 161 of pedestal 16.
In above-mentioned utility model linear vibration electric motor, owing to earlier catch 14 is arrived with spring part 13 laser spot weldings, form an integral body, spring part 13 laser spot weldings that will have catch 14 again are to the sidewall 161 of pedestal 16.Motor oscillator is when motion, and the stress at the junction surface 132 of spring part 13 will be loose by spot welding punishment, thereby the protection solder joint, avoid influence and the structural damage of spot welding to spring part 13 material properties, makes motor more reliable when work.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
