Touch pen with touch vibration function

Abstract

The invention provides a touch pen with a touch vibration function. The touch pen comprises a pen point (201), a shell (202), a pen point rod (203), a coil (204), a pressure sensor (205), an integrated circuit board (206), an operation switch plate (207), a piezoelectric vibration device (209) and a piezoelectric sensing device (210). By enabling the touch pen to generate touch vibration feedback, no matter whether the touch pen is used in non-contact or contact with a screen, a user can obtain the touch vibration experience. The piezoelectric sensing device is arranged on the outer surface of the touch pen, so that force applied by fingers of the user when the user holds the touch pen can be sensed, and a response is given. In the non-contact using process, the function similar to piezoelectric sensing can also be achieved, and the touch vibration intensity can be adjusted based on the holding force magnitude. The touch vibration of the touch pen does not interfere with the effects of the piezoelectric sensing function and the holding force detection function.

Description

technical field [0001] The present application relates to the structure of a touch input device, and more particularly, to a stylus with a tactile vibration function. Background technique [0002] In the recent few years, touch has developed into the mainstream operation mode of electronic equipment, especially in mobile phones, tablet computers, electronic paper books, GPS navigators, smart watches and other products, touch input has basically completely replaced Traditional keyboard input. [0003] Haptic vibration is a practical and experiential user feedback function in touch input technology. When the user's finger touches the touch panel of the electronic device, the electronic device will immediately vibrate slightly, which is sensed by the finger. This function allows the user to confirm that his touch input operation has been received by the device by feeling the vibration without being able to look at the display screen. Moreover, even if the user can watch th...

In another case, if input is made in such a way that the stylus touches the screen of the electronic device, although the tactile vibration of the body of the electronic device can be transmitted to the stylus from the pen tip during the contact process, this vibration must be It will affect the pressure sensor's sensing of the pressure on the pen tip rod, causing the sensed pressure to fluctuate abnormally, which in turn affects the normal detection and response of the electronic device to the pen force of the stylus, and has a negative impact on the "pressure sensitivity" function

[0013] Based on the above reasons, in the case of using a stylus for input, no matter whether it is a non-contact use or a contact use, the existing electronic equipment can only automatically turn off its tactile vibration function, which also makes the user use the stylus. The good experience in terms of tactile vibration is lost while the pen
