Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of vibrations smart pen that detects the vibration reminding function that has.

Background technology

With regard to existing market, various stationery especially pen are on the function or all of all shapes and colors on form, but the research aspect smart pen just just begins now.

In view of learning time has been grown easy to be absent-mindedly, common pen only plays the function of writing, and can't satisfy the effect that people are reminded.

The utility model content

The purpose of the utility model is exactly in order to address the above problem, and a kind of vibrations smart pen is provided.It has the writer is improved learning efficiency, and plays the advantage of vibration reminding function.

To achieve these goals, the utility model adopts following technical scheme:

On pen, be provided with a shaking device, also be provided with timing control apparatus, sensor and switch are provided with controller in the said timing control apparatus, and shaking device, sensor and switch are connected with controller in the timing control apparatus.

Said shaking device is flat polarization motor, and said flat polarization motor is arranged on a body terminus inner, and flat polarization motor is connected with controller.

Said sensor is the inertia-type seismological sensor, and said inertia-type seismological sensor is arranged on a body terminus inner, and is connected with controller.

Being provided with controller in the said timing control apparatus is the 89C52 single-chip microcomputer,

Said switch is arranged on a body middle part, is rotary switch, is provided with scale at a body middle part sidewall around rotary switch, and the every lattice of said scale are represented 30 seconds.

Described pen upward is provided with rubber sleeve at the place of holding a pen.

Said inertia-type seismological sensor comprises housing, said housing hollow cylindrical structure.Be provided with lead-in wire, coil, mandrel from top to bottom successively along axis direction in the housing; Magnet steel, damping cup, spring leaf; Said lead-in wire one end connects in case top, and the other end is connected with mandrel one end, and said magnet steel is arranged on the inner walls and cooperates with magnet steel; Said magnet steel is connected with mandrel, and the other end that said damping cup is located at mandrel is connected with the spring leaf that it is provided with down simultaneously, and spring leaf is connected with inner walls.

The utility model is provided with inertia-type moving-coil type electrokinetic transducer in the terminus inner of pen, and as the usefulness that detects vibrations, shaking device adopts minimum power supply to keep energy resource supply, and major function is to send vibrations.

In order to make sensor that the available frequency range than broad arranged, a damping ring of processing with red copper has been installed on the opposite of actuating coil.Through suitable physical dimension, can obtain desirable dimensionless attenuation coefficient x=0.7.In fact damping ring is exactly a short-circuited conducting sleeve that in magnetic field, moves.When work, this short-circuited conducting sleeve produces induced current.This electric current moves in magnetic field in company with damping ring again, thereby produces electromagnetic force, and this power is opposite with the direction of motion of moving part, is the resistance form and occurs, and its size is directly proportional with the movement velocity of moving part.Therefore, it is the linear damping power in this system.The shortcoming of this type of sensor is that the total weight of sensor when measuring all must be attached on the tested vibrating object, and this reliability to some vibration measurement result will produce bigger additional mass influence.

The beneficial effect of the utility model is,

1, adds rubber sleeve at the place of holding a pen and increase friction, make man-machine adaptation more.

2, shock detection adopts advanced electromechanical inertia-type seismological sensor, and it is more accurate to detect.

3, adopt flat polarization motor configuration, save the space.

4, a damping ring of processing with red copper being installed makes sensor that the available frequency range than broad arranged.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Among Fig. 1, on pen, be provided with a shaking device 1, also be provided with timing control apparatus sensor and switch, be provided with controller in the said timing control apparatus, shaking device 1, inertia-type seismological sensor 3 and switch are connected with controller in the timing control apparatus 2.

Said shaking device 1 is flat polarization motor, and said flat polarization motor is arranged on a body inside, and flat polarization motor is connected with controller.
