The invention relates to an electronic device and an operating method of the electronic device, and particularly to an electronic device with a touch-sensitive switch and an operating method of the electronic device.

At present, electronic devices such as mobile phones, computers, game consoles, etc., generally use a touch-sensitive switch. A user touches the touch-sensitive switch to open an electronic device or launch a program or return to a main page. A conventional touch-sensitive switch can sense a touch operation placed on the touch-sensitive switch. When the user places his finger on the surface of the touch-sensitive switch, the touch operation of the user's finger will be sensed, and then the electronic device is switched on to start the electronic device or start a program or return to the main page. However, when water vapor such as sweat is on the finger, the electric field will be interfered, so that the touch-sensitive switch cannot sense the touch operation, which makes the operation inconvenient. In addition, in the prior art, the touch-sensitive switch continuously generates and receives sonic signals to detect whether an operator is touching the touch without detecting that the operator is a living body (for example, a finger), resulting in very high power consumption and safety. Lower.

In view of this, it is necessary to provide an electronic device which is convenient to operate, does not consume power, and has high safety.

The control module is used for processing and analysis based on the outline information of the touch object, and the output is not activated according to the analysis result. Or start the instruction of the sonic touch-sensing component. The sonic touch-sensing component is used to sense the touch pressing action of the contact surface, and output a touch information indicating that the touch-sensitive switch is triggered.

It is also necessary to provide a method for operating an electronic device. The electronic device includes a touch-sensing switch for replacing a mechanical switch. The touch-sensing switch includes at least one cover plate, at least one radio frequency sensing component, and at least one sonic touch sensing component. And a control module, a contact surface is formed on a surface of one side of the touch sensor switch, the radio frequency sensor component and the acoustic wave touch sensor component are respectively installed on two opposite surfaces of the cover plate, the at least one radio frequency sensor component and the At least one sonic touch-sensing component is communicatively connected with the control module. The operation method of the electronic device includes: A step in which the radio frequency sensing component continuously sends an RF radio frequency signal; a step in which the radio frequency sensing component senses the outline of a touch object on the contact surface, and outputs the outline information of the touch object to the control module; the control mode The group receives the outline information of the touching object transmitted by the RF sensing component, and processes and analyzes the outline information of the touching object to determine whether the touching object is a living body. When the judgment result is that the touching object is a living body, the control module Generate a start-up instruction to start the step of the sonic touch-sensing component by the start-up instruction; the sonic touch-sensing component senses a touch-press action of the contact surface, and outputs a touch characterizing that the touch-sensitive switch is triggered Information steps The control module controls the operation steps of the electronic device according to the touch information.

Compared with the prior art, the touch sensing switch of the present invention uses a sensing function (for example, a fingerprint contour sensing function and a fingerprint sensing function) of a radio frequency sensing component and a sonic touch sensing component. The contour of the fingerprint of the finger is sensed, and the control module confirms whether the touched object is alive or not according to the fingerprint outline information. After confirming that the touched object is alive, the sonic touch sensor component is activated to turn on the mobile phone power or unlock the mobile phone lock screen. Therefore, the security is higher. In addition, after the sonic touch sensor component is activated, even if there is moisture such as sweat on the finger of the operator, the sonic touch sensor component is not affected by the water vapor, and the fingerprint pattern of the finger is normally sensed, so the fingerprint sensing is sensitive. And easy to operate. The control module confirms that the sonic touch sensing component is activated after the contact object is a living body, so that the sonic touch sensing component does not need to continuously generate and receive sonic signals to sense whether an operator touches, thereby saving power.

In the touch data in the module 71, the pressing pressure range data, the touch track data, and the number of pressing times are compared and analyzed, and the corresponding touch instructions are further output according to the analysis results.

Furthermore, the information processing module 73 may use software functional modules or hardware circuit modules to implement functions, that is, the information processing module 73 may be implemented by means of software functional modules, or may be implemented by Hardware circuit. It can be understood that the information processing module 73 may be an integrated circuit chip in the electronic device 200 integrated with the control function module, such as a single-chip microcomputer, a central processing unit (CPU), Microcontroller, etc. The functional modules of the information processing module 73 include a signal receiving unit 731, a data analysis unit 733, and an instruction generating unit 735.

In addition, after the sonic touch sensor assembly 50 is activated, even if there is moisture such as sweat on the finger of the operator, the sonic touch sensor assembly 50 is not affected by the water vapor, and normally senses the fingerprint of the finger, thereby fingerprint sensing. Sensitive and easy to operate. After the control module 70 confirms that the contact object is a living body, the sonic touch sensor assembly 50 is activated, so that the sonic touch sensor assembly 50 does not need to continuously generate and receive sonic signals to sense whether an operator touches, and then it can Save electricity.

In addition, since the touch sensing switch 100 utilizes the sensing functions of the radio frequency sensing component 30 and the sonic touch sensing component 50, compared with the physical buttons that realize the switching function by pressing in the prior art, The touch sensing switch does not need to be provided with a rubber or elastic substance to perform a pressing action, which avoids affecting the realization of the switch function due to elastic fatigue caused by the rubber or the elastic substance, thereby helping to extend the life of the touch sensing switch. In addition, the contact surface 11 of the touch-sensitive switch can be made flat, And it can be a flat surface with the glass surface of the cover 10 of the electronic device (such as a mobile phone), so it is conducive to a flat appearance, and it is not easy to hide dirt and dirt, and it is more neat and beautiful.
