The invention provides a kind of extensional vibration motor, this vibrating motor elastic piece structure to longitudinal linear vibration motor
And magnetic circuit distribution design is improved so that it is the vibrating mass assembly of cuboid-type can be provided stable, the support of balance
With rebound effect power.On the other hand, the magnetic circuit of extensional vibration motor is also distributed and is improved by the present invention so that vibrating mass group
Part can be by the electromagnetic force of size uniform, enough in vibration processes, it is ensured that vibrating mass assembly produces effective vibration.
As it is shown in figure 1, in the detailed description of the invention of the present invention, described extensional vibration motor includes can housing 1, vibrating mass
Assembly, shell fragment 3 and circuit unit, described housing 1 is internal has receiving chamber, and the receiving chamber of housing 1 is used for carrying extensional vibration
Each parts of motor.Especially, in order to reduce volume, it is rectangular for reducing the space taken, described housing 1 and the entirety accommodating chamber
Body or class rectangular structure.Class rectangular structure of the present invention is the length, width and height feature with basic rectangular structure,
But one of them or several surface are not plane, but use cambered surface or folding face；Or, it is also possible to the angle between each surface is not
It it is 90 °.The shape of class rectangular structure is not specifically limited by the present invention, and the anisotropic approach of similar rectangular structure belongs to
Class rectangular structure of the present invention.Figure 14 shows housing and the knot of mass of a kind of opposite sex vertical linear vibrating motor
Structure.
Described vibrating mass assembly includes mass 21 and the Magnet 22 being fixedly installed on mass 21, described mass 21
As the main counterweight of vibrating mass assembly, the Magnet 22 of described mass 21 produces electromagnetic force for coordinating with coil 41,
Drive vibrating mass assembly extensional vibration.Especially, vibrating mass assembly is overall in cuboid-type or class cuboid-type structure.
In the vibrating motor that the present invention provides, described vibrating mass assembly mainly structure in noncircular cross section, such as may be used
To be the structure such as cuboid-type, fillet cuboid-type, so vibrating mass assembly has the differentiation of long axis direction and short-axis direction.Institute
Stating the direction that long axis direction is the length along vibrating mass assembly, described short-axis direction is then the width along vibrating mass assembly
Direction.Shown in phantom above-mentioned long axis direction and the short-axis direction that in Fig. 1, two length on mass 21 are different.
