Problems solved by technology

However, using a mechanical button requires a relatively high pressure to trigger the button, resulting in a short lifespan of the mechanical button; and a mechanical button can only correspond to one function
Therefore, the setting of mechanical buttons is very easy to affect the user experience

Embodiment Construction

[0030] see figure 1 , the touch control system 100 in a preferred embodiment of the present invention includes a plurality of sensors 10, a multi-way switch 20 respectively connected to the plurality of sensors 10, and a signal transmission control circuit connected to the multi-way switch 20 30, a signal receiving control circuit 40, and a digital controller 50 connected to the signal sending control circuit 30 and the signal receiving control circuit 40.

[0031] The touch control system 100 also includes a substrate 70, the substrate 70 has an exposed touch surface 71 (such as Figure 4 and Figure 5 As shown), the touch surface 71 is a surface on which objects such as fingers perform touch operations during use. The plurality of sensors 10 can be disposed on a side of the substrate 70 away from the touch surface 71 .

[0032] In this embodiment, each sensor 10 is used for sending ultrasonic signals and receiving reflected ultrasonic signals. The plurality of sensors 10...

Abstract

The invention discloses a touch system. The system comprises multiple sensors, a multiway switch, a signal sending control circuit, a signal receiving control circuit and a digital controller, whereineach sensor is used for sending ultrasonic signals and receiving the ultrasonic signals which are reflected back; the multiway switch is connected with the multiple sensors separately, and is used for being selectively communicated with one of the multiple sensors; the signal receiving control circuit is connected with the multiway switch and is used for driving the sensors to send the ultrasonicsignals; the signal receiving control circuit is connected with the multiway switch, and is used for making the sensors receive the ultrasonic signals; the digital controller is electrically connected with the signal sending control circuit, the signal receiving control circuit and the multiway switch. The invention further provides an electronic device applying the touch system and a method foradopting the touch system to conduct touch judgment.

Description

technical field [0001] The invention relates to a touch control system, an electronic device using the touch control system, and a touch determination method for the touch control system. Background technique [0002] Electronic products are usually provided with mechanical keys. However, when using a mechanical button, a large pressure is required to trigger the button, resulting in a short life of the mechanical button; and a mechanical button can only correspond to one function. Therefore, the setting of the mechanical buttons is very likely to affect the user's experience. Contents of the invention [0003] In view of this, it is necessary to provide a touch control system that effectively solves the above problems and realizes button functions. [0004] A touch control system comprising: [0005] A plurality of sensors, each sensor is used to send ultrasonic signals and receive reflected ultrasonic signals; [0006] a multi-way switch, which is respectively connec...
