As shown in Figure 1, in the specific implementation mode of the present invention, the extensional vibration motor includes can shell 1, vibrating mass
Component, shrapnel 3 and circuit unit, 1 inside of the shell have accommodating chamber, and the accommodating chamber of shell 1 is for carrying extensional vibration
Each component of motor.Particularly, in order to reduce volume, reduce the space occupied, the entirety of the shell 1 and accommodating chamber is in rectangular
Body or class rectangular parallelepiped structure.Class rectangular parallelepiped structure of the present invention is the length, width and height feature with basic rectangular parallelepiped structure,
But one of them or several surfaces are not plane, but use cambered surface or folding face；Alternatively, angle that can also be between each surface is not
It is 90 °.The present invention does not carry out concrete restriction to the shape of class rectangular parallelepiped structure, and the anisotropic approach of similar rectangular parallelepiped structure belongs to
Class rectangular parallelepiped structure of the present invention.Figure 14 shows a kind of knot of the shell and mass block of anisotropic vertical linear vibrating motor
Structure.
The magnet 22 that the vibration block assembly includes mass block 21 and is fixed on mass block 21, the mass block 21
As the main counterweight of vibration block assembly, the magnet 22 of the mass block 21, which is used to coordinate with coil 41, generates electromagnetic force,
Driving vibration block assembly extensional vibration.Particularly, vibration block assembly is in integrally cuboid-type or class cuboid-type structure.
In vibrating motor provided by the invention, the vibration block assembly is in mainly the structure of noncircular cross section, such as can
To be the structures such as cuboid-type, rounded cuboid type, so vibration block assembly has the differentiation of long axis direction and short-axis direction.Institute
It is along the direction of the length of vibration block assembly to state long axis direction, and the short-axis direction is then the width along vibration block assembly
Direction.Two different dotted lines of length in Fig. 1 on mass block 21 show above-mentioned long axis direction and short-axis direction.

Receive the inner surface connection of chamber, shrapnel 3 and the junction of accommodating chamber and to vibrate block assembly corresponding along another end position of long axis direction.
As shown in Fig. 2, the shrapnel 3 of upside is connected to the top surface of accommodating chamber, link position accommodating chamber left end, with vibration block assembly
Left position corresponds to；The shrapnel 3 of downside is connected to the bottom surface of accommodating chamber, link position accommodating chamber right end, with vibrating mass group
The right end position of part corresponds to.Two shrapnels 3 are centrosymmetric form relative to the vibration block assembly, as shown in Figure 2.
Preferably, as shown in figure 3, in order to further make vibration block assembly there are more magnetic fields to pass through line in vibration processes
Circle 41, the height of itself of the coil 41 can be more than the height of the vibration block assembly itself.And it vibrates block assembly or more and shakes
For dynamic amplitude then less than or equal to the altitude range of itself of coil 41, the amplitude for vibrating block assembly can be by the knot of shrapnel component
Structure is limited.In this way, vibration block assembly is in always in the altitude range of coil 41, magnetic field can more pass through coil
41, magnetic flux density is improved, and then improve electromagnetic force.In addition, the upper and lower surface of the magnet could be covered with magnetic conductive board,
The magnetic conductive board can make the region where magnetic field concentration deflection coil 41, improve the magnetic flux of coil 41.
