Abstract
The utility model relates to a double magnetic steel flat vibration motor, belonging to the communication technology field of a flat vibration motor used in mobile phone manufacturing. The flat vibration motor in the prior art is characterized in that a single magnetic steel is arranged on the upper surface of a lower bracket, and because the magnetic steel and an electric brush are on a same surface, the electric brush bears not only the weight pressure of a rotor, but also the attractive force of the magnetic steel to the rotor at the same time, not being conducive to the service life and starting performance of the vibration motor. In the utility model, a magnetic steel is added on the inner surface of the top of a machine shell, the upper and lower two magnetic steels forms a stronger magnetic field gather magnetic energy according to the arrangement of the magnetic poles. When the flat motor is electrified, the starting performance of the flat motor can be reduced effectively, so that the response of the flat vibration motor is more sensitive, and the vibration sense of the flat motor can be improved; and at the same time, the pressure of the motor rotor to the electric brush is reduced, and the service life of the double magnetic steel flat vibration motor is improved effectively.
Description
Technical field
The utility model relates to a kind of vibrating motor for mobile phone, relates in particular to a kind of mobile phone with two magnet steel flat vibration motors, belongs to communication product manufacturing technology field.
Background technology
A kind of flat vibration motor of prior art is as shown in Figure 1, and it mainly is made up of with the casing that is down cup-like structure that is connected with bottom bracket bottom bracket.Be arranged to the boss shape in the centre position of bottom bracket upper surface, boss has through hole, and rotating shaft is pressed in the through hole.The upper surface of bottom bracket is provided with magnet steel, brush and brush substrate.One end of brush and brush substrate is electrically connected through welding, and the other end extends to outside the casing.Bottom bracket, rotating shaft, magnet steel, brush and brush substrate are formed bottom bracket assembly formation stator jointly and are played a supportive role.Coil and weight are arranged on the upper surface that turns to substrate, and oiliness bearing, weight, coil and switching-over substrate form rotor through injection moulding.When motor is switched on, brush with turn to substrate conducting and switching-over, make coil and magnet steel produce power and make rotor rotation, and the off-centre through weight produces and vibrates through the action of a magnetic field.This kind structural vibrations motor, because magnet steel, brush and brush substrate are arranged on identical faces, make the volume of magnet steel reduce, thereby have reduced the vibrational energy of motor.Simultaneously, because magnet steel and brush make rotor produce pressure to brush in identical faces, brush not only wants the pressure of bear rotor weight also will bear the suction of magnet steel to rotor simultaneously.Be unfavorable for the useful life of motor and the raising of starting performance.
Summary of the invention
For solving the problem that prior art exists, the utility model provides a kind of improved pair of magnet steel flat vibration motor, and this improved pair of magnet steel flat vibration motor realized through following technical scheme.A kind of improved pair of magnet steel flat vibration motor mainly is made up of with the casing that is down cup-like structure that is connected with the bottom bracket upper surface bottom bracket.In casing, under the big or small constant prerequisite in space, set up a magnet steel at the inner surface at casing top.Should be up and down two blocks of magnet steel arrangement mode through magnetic pole make it produce the magnetic field of constant intensity.Boss shape structure is arranged in the centre position of bottom bracket upper surface, and boss has through hole, and rotating shaft is pressed in the through hole, and the upper surface of bottom bracket is provided with brush and brush substrate, and an end of brush and brush substrate is electrically connected through welding, and the other end extends to outside the casing.Magnet steel, rotating shaft, brush and brush substrate constitute bottom bracket assembly formation stator jointly and play a supportive role.Coil is arranged on the both sides that turn to upper surface of base plate with heavy bell, coil, heavy bell, oiliness bearing and turn to substrate to constitute rotor and be installed in the rotating shaft through injection moulding, and rotor is that the center rotatablely moves with the rotating shaft.Coil forms through welding with the switching-over substrate and is electrically connected, and the two ends of oiliness bearing are provided with pad.When motor was switched on, brush was delivered to coil with switching-over substrate conducting and switching-over with power.Coil and magnet steel produce power through the action of a magnetic field and make rotor rotation, and produce vibration through the off-centre of weight.Because inner surface is set up a magnet steel on the upper casing top.Two blocks of magnet steel are assembled magnetic energy through the more powerful magnetic field of the arrangement mode formation of magnetic pole up and down, have effectively reduced the starting time and the dwell time of motor, make the motor reaction sensitive more.And the sense of shaking that can improve flat motor.
As preferably: the external diameter that the oiliness bearing two ends are provided with pad equates with the external diameter of oiliness bearing.

Fig. 2 is the flat motor configuration sketch map that shakes of two magnet steel after improving.
Embodiment
Below through embodiment and combine accompanying drawing 1 and accompanying drawing 2, the technical scheme of the utility model is further specified.A kind of for improving the sense of shaking, reduce two magnet steel flat vibration motors of start-up time and dwell time.Its technical scheme mainly by bottom bracket 1 be arranged on 7 of the casings that is down cup-like structure that are connected with the upper surface of bottom bracket 1 and constitute.The centre position of bottom bracket 1 upper surface is provided with the boss shape, and boss has through hole, and rotating shaft 4 is pressed in the through hole.Bottom bracket 1 upper surface is provided with lower magnetic steel 21, brush 6 and brush substrate 3.One end of brush 6 and brush substrate 3 is electrically connected through welding, and the other end extends to outside the casing.Lower magnetic steel 21, brush 6 constitute stator with brush substrate 3 with rotating shaft 4 and play a supportive role.Upper magnetic steel 22 is arranged on the inner surface at casing 7 tops, and coil 9 is arranged on the both sides that turn to substrate 8 upper surfaces with heavy bell 12.Coil 9, weight 12, oiliness bearing 10, switching-over substrate 8 form rotor through injection moulding.Rotor is installed in the rotating shaft, and the two ends of oiliness bearing 10 are provided with pad 5, and rotor is that the center rotatablely moves with the rotating shaft.Rotor its rubbing surface when rotating has reduced the coefficient of friction of oiliness bearing 10 on pad 5.Coil 9 forms through welding and switching-over substrate 8 and is electrically connected.When motor is switched on, brush 6 with turn to substrate 8 conductings and switching-over with power delivery to coil 9.The action of a magnetic field that the pole arrangement mode of coil 9 and upper magnetic steel 22, lower magnetic steel 21 forms produces power and makes rotor rotation, and produces vibration through the off-centre of weight 12.This technical scheme produces more powerful magnetic field and assembles magnetic energy through upper magnetic steel 22 and lower magnetic steel 21 and the arrangement through magnetic pole are set, and has effectively reduced the starting time and the dwell time of flat vibration motor, makes flat vibration motor reaction sensitivity more.And the sense of shaking that has significantly improved flat motor.
