Background technique

Since the handwriting recognition circuit device can replace the mouse, and is more suitable for the user to manually input characters and patterns than the mouse, the improvement of the handwriting recognition circuit device is a rapidly developing field in recent years. The earliest handwriting recognition circuit device can be regarded as replacing the mouse with a pen, and in order to improve the user's convenience, the mouse is usually replaced by both a wireless pen and a digital tablet (tablet), and the tip of the wireless pen is usually It corresponds to the left button of the mouse. Although traditional pen input products have been available for many years, similar products only focus on single-function applications such as drawing or Chinese input.

The current pen-type input product is usually a wireless pressure electromagnetic induction circuit device. Referring to FIG. 1, it is a circuit block diagram of an existing wireless electromagnetic induction device. The wireless pressure electromagnetic sensing device includes: a cordless pen and a tablet. There is an oscillating circuit composed of inductance and capacitance (LC) in the wireless pen. When the pen tip is touched, the inductance will change, so the oscillating frequency will also change accordingly. The greater the pressure on the pen tip, the greater the change in inductance, and thus the greater the change in the oscillation frequency. Therefore, the magnitude of the pressure applied to the pen tip can be known from the change in frequency. There are also two switch buttons on the side of the wireless pen. When the buttons are joined and separated, the capacitance in the LC oscillator changes to change the transmitting frequency of the pen. The switch button pressed by the user can be detected from the different frequency changes. In addition, the digital board (tablet) also includes components such as a detector (detector), an amplifier (Amplifier), and an analog-to-digital converter. The central area of this type of traditional handwriting tablet is an induction loop, and there are unidirectional antennas arranged equidistantly in an array on both sides of the induction loop. The main purpose of this one-way antenna loop is only to receive the electromagnetic wave signal emitted by the dedicated wireless pen. When the wireless electromagnetic pen emits electromagnetic waves, the one-way antenna will receive the electromagnetic waves and obtain relevant data through the digital board by means of electromagnetic induction. However, the traditional wireless pressure electromagnetic induction device only has the simple function of receiving the signal emitted by the peripheral device and detecting its position. Therefore, the present invention provides a new wireless pressure electromagnetic induction system in order to strengthen and increase the function of the wireless pressure electromagnetic induction device.
