That is, in the linear vibration motor of the present invention, the vibrator includes at least two adjacent permanent magnets, and the adjacent end polarities of the two adjacent permanent magnets are the same, and the magnetizing direction of the permanent magnet is perpendicular to the axis direction of the coil in the stator.
Specifically, fig. 1 and 2 show an overall explosion structure and a combined structure of a linear vibration motor according to an embodiment of the present invention, respectively.
As shown in fig. 1 and 2 in common, the linear vibration motor of the present embodiment mainly includes a housing, a vibrator, and a stator, the stator and the vibrator being arranged in a vertical direction. Wherein, the shell comprises an upper shell 1 and a rear cover 2; the vibrator comprises a balancing weight 31 and a vibrating block, wherein the vibrating block consists of three permanent magnets 32a, 32b and 32c which are adjacently arranged and magnetic conductive yokes 33a and 33b which are respectively arranged between the adjacent permanent magnets; the stator includes two coils 41a, 41b provided corresponding to the vibrator and magnetically permeable cores 42a, 42b provided in the coils, respectively.

In which the combined structure of the vibration mass and the stator is as shown in fig. 3a and 3 b. Among the three permanent magnets arranged adjacently, the polarity of the adjacent end of each permanent magnet and the adjacent permanent magnet is the same, namely the permanent magnets are arranged in an S-N, N-S, S-N sequence (shown in figure 3 a) or an N-S, S-N, N-S sequence (shown in figure 3b), the magnetic conduction yokes are arranged between the adjacent permanent magnets, and the magnetizing directions of the permanent magnets are perpendicular to the axial direction of the coil of the stator. Here, the axial direction of the coil is the direction in which the central axis of the coil and the magnetic core therein is located, in the embodiment shown in fig. 3a and 3b, the magnetizing direction of the magnet is the horizontal direction, and the axial direction of the coil is the vertical direction. Since the two adjacent permanent magnets have the same polarity, a repulsive force is generated between the two ends, and thus the magnetic lines of force of the permanent magnets can concentrate through the magnetic yoke between the two adjacent permanent magnets and the coil disposed below the vibrating mass, thereby increasing the magnetic flux passing through the coil as much as possible.
The operation of the linear vibration motor of the present invention will be briefly described with reference to fig. 4. According to the left-hand rule for judging the stress direction of the electrified conductor in the magnetic field, the left hand is stretched, so that the thumb is perpendicular to the other four fingers and is in the same plane with the palm; the magnetic induction line enters from the palm, and the four fingers point to the direction of current, and the direction pointed by the thumb is the direction of the ampere force exerted on the electrified lead in the magnetic field. Assuming the direction of the current in the coil, denoted as "The direction of current flow is perpendicular to the drawing and inward, and is marked ""Current direction is perpendicular to the drawing plane and out, assuming the first coil is"And", the second coil must also be"And", so that the coils are all forced to the right F ', and because the coils are fixed, the permanent magnet is forced to the left F' based on the relation between the acting force and the reacting force. So, receive the permanent magnet of driving force left and just drive the balancing weight and do translational motion left together to the left spring of extrusion balancing weight, the spring on tensile balancing weight right side. Similarly, when the direction of current flow is changed, according to the left-hand rule, the magnetic force F received by the coilThe direction is to the left. However, because the coil is fixed, the permanent magnet is acted by the F' with the same size and the opposite direction to the F, the permanent magnet which is acted by the right driving force drives the balancing weight to do the right translation movement together, and simultaneously, the springs at the two ends of the balancing weight are stretched/extruded continuously after being restored from the extruding/stretching state. The above motions are alternately performed, so that the vibrator formed by the vibrating mass composed of the permanent magnet and the magnetic yoke and the counterweight block reciprocates in a direction parallel to the mounting plane of the stator.

In the embodiment shown in fig. 1 and 2, the vibrating block is embedded and fixed in the balancing weight to drive the balancing weight to vibrate horizontally. Specifically, the middle part of the balancing weight is provided with an avoiding structure for avoiding the stator, and the central position of the avoiding structure on the balancing weight is provided with a groove for accommodating the vibrating block.

In addition, the linear vibration motor of the present invention further includes two vibration guide shafts (51a, 51b), a limiting spring (52a, 52b) and a limiting block (53a, 53b) disposed at both ends of the weight block 31, and the limiting spring is sleeved on the vibration guide shafts 51a, 51 b. In the embodiment shown in fig. 1 and 2, the limiting blocks 53a and 53b are respectively fixed on the upper casing 1, the two vibration guide shafts 51a and 51b are respectively fixed at two ends of the counterweight 31, and the limiting blocks 53a and 53b are further provided with guide holes for the vibration guide shafts to reciprocate. Thus, the vibrating mass drives the weight block 31 and the vibration guide shafts 51a and 51b fixed to both ends of the weight block 31 to vibrate within a limited range of the guide hole under the action of the magnetic field generated after the stator is energized.
Wherein, the limiting springs 52a, 52b respectively sleeved on the vibration guide shafts 51a, 51b are respectively limited between the balancing weight 31 and the corresponding limiting blocks 53a, 53b, and provide elastic restoring force for the vibration of the vibrator.
In addition, in order to reduce the friction force between the vibration guide shaft and the guide hole as much as possible and improve the product quality, the end of the vibration guide shaft, which is deep into the guide hole, can be sleeved with the shaft sleeves 54a and 54b, and the contact surface of the shaft sleeve and the guide hole is smooth and wear-resistant. The increase of axle sleeve has reduced the area of contact of vibration guiding axle and guiding hole to can adopt the smooth wear-resisting material preparation axle sleeve in density height, surface, can reduce the frictional force between vibration guiding axle and the guiding hole as far as possible on the basis that does not increase the cost, improve lubricated degree.

Therefore, the vibrating block drives the balancing weight and the limiting blocks fixed at the two ends of the balancing weight to vibrate along the vibration guide shaft within the limited range of the guide hole under the action of a magnetic field generated after the stator is electrified.
Obviously, the amplitude of the vibrator vibration determines the depth of the vibration guide shaft penetrating into the guide hole, the depth of the tail end of the vibration guide shaft penetrating into the guide hole from the bottom end of the guide hole and the width of the edge of the avoiding structure from the outer edge of the stator. In the embodiments shown in fig. 1 and 2, and fig. 3a and 3b, the horizontal distance d between the magnetic yoke and the magnetic core corresponding to the magnetic yoke is in the range of [0.1mm, 0.3mm ], that is, the horizontal distance between the center line of each magnetic yoke and the center line of the corresponding (i.e., nearest) magnetic core of the stator is 0.1-0.3 mm, so the depth of the corresponding vibration guide shaft penetrating into the guide hole, the depth of the vibration guide shaft penetrating into the end of the guide hole from the bottom end of the guide hole, and the width of the edge of the avoiding structure from the outer edge of the stator should be slightly larger than 0.2 mm.
