REAL HANDWRITING STYLUS AND TOUCH DEVICE HAVING RADIO FREQUENCY TRANSMITTING AND RECEIVING FUNCTION

摘要

The present invention discloses a real handwriting stylus and a touch device, it includes a stylus shell, a battery inside the stylus shell, a stylus system circuit inside the stylus shell as well as touch pressure sensitive components and a touch module inside the stylus shell, the touch pressure sensitive components include a nib, a nib touch switch and a nib pressure inductor; the stylus system circuit includes a charging circuit, a power control and a shutdown delay circuit, a power voltage conversion circuit, function keys, a RF modulating and RF transceiver circuit and a signal generating circuit; the RF modulating and RF transceiver circuit connects with the nib pressure inductor and the function keys, whereby acquiring the nib pressure signals and the function key signals respectively, and RF modulating and outputing RF modulation signals; the RF modulating and RF transceiver circuit can receive frequency hopping command RF signals of the touch component, then output frequency-hopping signals to the signal generating circuit; the signal generating circuit connects with the RF modulating and RF transceiver circuit, whereby acquiring the frequency-hopping signals to proceed frequency hopping operation, therefore the stylus and the touch device formed from the stylus and the touch module disclosed in the present invention have very strong anti-interference features, and the real handwriting written effects, the function keys can define any shortcut keys on external device.
