Description

Technical Field

[0001] The utility model relates to a handwriting device, in particular to a handwriting device capable of slight vibration, belonging to the technical field of handwriting devices. Background Art

[0002] In addition to being used for inputting text, symbols, graphics, etc., a handwriting tablet can also provide a cursor positioning function, so that the handwriting tablet can replace both the keyboard and the mouse and become an independent input tool. The pen design of the handwriting tablet is divided into two types: pressure-sensitive and non-pressure-sensitive. The pressure-sensitive handwriting tablet can sense the force of the stylus on the tablet, thereby producing strokes of different thicknesses. The handwriting tablet can be connected to the computer via a data cable, and then the handwriting tablet can replace the mouse, keyboard and other functions.

[0003] Data transmission on traditional handwriting tablets is achieved by generating a slight vibration in the piezoelectric speaker through the vibration generated by handwriting. The piezoelectric speaker converts the vibration into an electrical signal and transmits it to the computer. Traditional piezoelectric speakers are directly installed inside the handwriting tablet. When the piezoelectric speaker is damaged, it is inconvenient to remove the piezoelectric speaker for repair. At the same time, it is also inconvenient to replace the internal piezoelectric speaker, which affects the performance of the handwriting tablet. Utility Model Content

[0034] When the present invention is in use, when the piezoelectric speaker 202 needs to be repaired and maintained, the pressing plate 203 can be slid downward, and the sliding of the pressing plate 203 drives the slider 206 to slide, and the spring 208 is compressed. At the same time, the pressing plate 203 drives the clamping block 204 to no longer engage with the clamping slot 205 on the mounting frame 201, thereby facilitating the removal of the mounting frame 201 from the interior of the handwriting tablet 1, and then the piezoelectric speaker 202 can be repaired or replaced with a new one. The setting of the guide rod 207 improves the sliding stability of the slider 206 and prevents the spring 208 from deviating. When the handwriting tablet 1 needs to be used, The sliding sleeve 405 drives the slide bar 406 to slide inside the sliding groove 407. The sliding sleeve 405 no longer blocks the stylus 403.

Then, the required spare pen tip 409 is unscrewed from the threaded column 408 and the stylus tip 409 is removed. Unscrew the threaded pen tip 404 on the stylus 403, install the spare pen tip 409 on the stylus 403, and rotate the removed threaded pen tip 404 onto the threaded column 408, then loosen the protective plate 502, the torsion spring 503 resets, and then drives the installation shaft 501 to rotate, and the installation shaft 501 drives the protective plate 502 to buckle on the handwriting board 1, write on the handwriting board 1 with the stylus 403, and the piezoelectric speaker 202 collects the vibration signal generated and converts it into an electrical signal to transmit to the computer end, thereby replacing the mouse or keyboard to control the computer. When the angle of the handwriting board 1 needs to be adjusted , the support bar 302 can be rotated, and the support bar 302 drives the first damping shaft 301 to rotate. The support bar 302 is in direct contact with the desktop. The handwriting tablet 1 is rotated to adjust the writing angle. The setting of the connecting bar 306 improves the synchronization of the rotation of the support bar 302 and improves the support stability. Then, the rotating bar 304 is rotated, and the rotating bar 304 drives the second damping shaft 303 to rotate. After rotating the rotating bar 304 to a suitable angle, the connecting rod 305 is slid, and the connecting rod 305 is stuck in a suitable limit groove 307, thereby further supporting the handwriting tablet 1 and improving the stability during writing.
