Embodiment Construction

[0027] This embodiment is only an illustration of an implementation, and is not the only implementation of this principle.

[0028] A force-sensitive handwriting device based on a magnetoelastic body includes a pen tip 1 , a front sheath 2 , a force-sensitive device 3 , a resonant circuit board 4 , a pen holder 5 , a tail plug 6 , a first button 7 , and a second button 8 .

[0029] The nib 1 is made of permalloy material coated with nylon, and the nib is compressed with the magnetic elastic material through the threaded front protective sleeve 2 to ensure that the nib does not loosen, and the force of the nib is transmitted vertically to the magnetic elastic body.

[0030] The magnetoelastic body 14 adopts a nickel-iron magnetoelastic material with low magnetoelasticity, and the magnetoelastic material is processed into a cylindrical shape, and its force sensitive range is about several hundred grams.

[0031] The bobbin 12 around which the coil is wound is in close contact wi...

Abstract

The invention relates to the field of handwriting input. The invention discloses a force-sensitive handwriting device based on a magnetic elastomer. The pen comprises a pen point (1), a front end sheath (2), a force sensitive device (3), a resonance circuit board (4), a pen container, a first key (7) and a second key (8), wherein the pen point (1) is a rigid body of which the front end is conicaland the rear end is columnar or trapezoidal step columnar; the front-end sheath (2) is a conical sleeve with openings at the front end and the rear end; the pen container is a sleeve which is detachably connected with the pen point (1); wherein the front end of the pen point (1) is located in the front-end sheath (2), the head of the pen point (1) extends out of the sheath (2), the tail of the penpoint (1) is located in the pen container, the force-sensitive device (3) and the resonance circuit board (4) are located in a sleeve, and the first key (7) and the second key (8) are located on theside wall of the pen container.

Description

technical field [0001] The invention relates to the field of handwriting input, in particular to a handwriting device capable of sensing writing pressure. Background technique [0002] At present, there are many input methods for mobile phones and tablets, including touch, keyboard, and even a wirelessly connected mouse for input. Among them, the handwriting input device is a device with high usage rate, including finger touch and stylus. The most common electromagnetic board for handwriting input consists of an antenna board covered with electromagnetic coils and a stylus containing an inductive coil. The stylus is used as a user input tool, and its pen force plays a vital role in simulating the feel of paper. [0003] Chinese patent CN01145283 discloses a stylus, which at least includes a core, an elastic element, a first magnetic element with a coil wound by at least one strand of wire, a second magnetic element, a slider, A hollow sleeve with an annular spacer inside ...
