Specific embodiment
Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of nonsymmetrical vibration haptic feedback devices, including a shell 10, a mass block
20, a stacked piezoelectric ceramics 30, a flexible substrates 40 and two fixed mechanisms.
Two fixed mechanism between left and right every and 40 left and right sides portion of flexible substrates be respectively and fixedly connected on two fixed mechanisms, make
The bridge joint of flexible substrates 40 is obtained in two fixed mechanisms；The fixed mechanism include longer fixed block 60,61 and shorter fixed block 50,
51, a longer fixed block 60 and a shorter fixed block 50 clamp affixed 40 left side of flexible substrates, another longer 61 He of fixed block
Another shorter fixed block 51 clamps affixed 40 right side of flexible substrates, because fixed block is divided into longer fixed block and shorter fixed block,
Therefore flexible substrates 40 under the restriction effect of fixed block, the flexible substrates 40 deform downward deformation segment length (by compared with
Long fixed block limitation) it is less than the deformation segment length (being limited by shorter fixed block) deformed upward.In specific structure: longer fixed block
60, the side alignment of 61 lateral wall, the lateral wall of shorter fixed block 50,51, flexible substrates 40.Further, pass through screw
Longer fixed block 60,61 and shorter fixed block 50,61 is set to fix to clamp 40 side of flexible substrates.
Ceramic 30 lower end surfaces of the stacked piezoelectric are fixed in the middle part of 40 top surface of flexible substrates, on the stacked piezoelectric ceramics 30
End face is connected with mass block 20.The stacked piezoelectric ceramics 30 and mass block 20 are between two shorter fixed blocks 50,51.
The shell 10 is in cuboid box-like, and the mass block 20, stacked piezoelectric ceramics 30, flexible substrates 40 and fixed
Mechanism is all set in shell 10, and the longer fixed block 60,61 is fixedly arranged in shell 10.In specific structure, longer fixed block 60,
It is fixed between 61 and 10 bottom surface of shell using glue bonding or chimeric or pressing mode.
Among present embodiment: the specific working mode of haptic feedback devices are as follows:
In initial position, flexible substrates 40 are in straight state, exist between 10 roof of 20 top of mass block and shell
Gap；
When stacked piezoelectric ceramics 30 receive driving signal, the stacked piezoelectric ceramics 30 because inverse piezoelectric effect can frequently into
Row longitudinal extension.When carrying out longitudinal elongation for the first time, flexible substrates 40 can be with 30 elongation of stacked piezoelectric ceramics and quickly from first
Toward prolonging direction (downward) elastic deformation occurs for beginning position；When stacked piezoelectric ceramics 30 are shunk, the past contraction side of flexible substrates 40
Elastic deformation occurs to (upward)；Since flexible substrates 40 occur elastically-deformable length and are less than when stacked piezoelectric ceramics 30 extend
Elastically-deformable length occurs for flexible substrates 40 when contraction, therefore the amplitude of 40 deformation of flexible substrates is greater than when extending when contraction
Amplitude drives mass block 20 to hit shell 10 under the action of 40 natural resiliency of inertia and flexible substrates.In the control of driving signal
It under system, repeats the above steps, circulation is repeatedly.
The elastic deformation that the mass block 20 hits shell 10 and the generation different directions of flexible substrates 40 can generate vibration
Effect, mass block 20 directly obtain mechanical energy from stacked piezoelectric ceramics 30, so that mechanical energy propagation is short out, energy loss is small, bullet
Property substrate 40 play the role of amplify amplitude, further enhance the vibrating effect of the haptic feedback devices.
The above is only the preferred embodiment of the present invention, the range implemented of the present invention that therefore, it cannot be limited according to, i.e., according to
Equivalent changes and modifications made by the invention patent range and description, should still be within the scope of the present invention.
