The induction module 110 may be disposed inside the housing of the electronic device. Through holes are respectively opened in the housing at the position of the infrared sensor, so that the infrared sensor can scan and detect the distance between the user's finger of the electronic device and the screen page-turning area through this small hole. The control module 120 in this embodiment may adopt a microcontroller unit (MCU), and the vibration module 130 may be an ultrasonic transmitter.

[0030] Example 2

[0031] Example 2 of the present invention is further optimized based on Example 1. Figure 2 FIG. is a schematic structural diagram of a simulated touch electronic device provided in Example 2 of the present invention. As Figure 2 shown, the electronic device 200 for realizing touch simulation in this embodiment includes:

[0032] An induction module 210, communicatively connected to the control module 220, for detecting the distance between the user's finger and the screen page-turning area of the electronic device, generating and sending detection result information to the control module 220;

[0033] A control module 220, for sending a touch simulation instruction to the vibration module 230 according to the received detection result information;

[0034] A vibration module 230, connected to the control module 220, for sending ultrasonic waves in the direction of the user's finger according to the received touch simulation instruction.

[0035] Specifically, in this embodiment, the electronic device 200 may be a mobile phone or a tablet. The induction module 210 may be an infrared sensor. The induction module 110 may be disposed inside the housing of the electronic device. Through holes are respectively formed in the housing at the position of the infrared sensor, so that the infrared sensor can scan and detect the distance between the user's finger of the electronic device and the screen page-turning area through this small hole. The screen page-turning area in this embodiment may be the lower right corner of the electronic device screen. The control module 220 in this embodiment may adopt a microcontroller unit (MCU), and the vibration module 230 may be an ultrasonic wave transmitter. Ultrasonic waves are sound waves with a frequency higher than 20,000 hertz. In practical applications, they are further divided into power ultrasonic waves and detection ultrasonic waves. It has good directivity, strong penetration ability, is easy to obtain a relatively concentrated sound energy, and has a long propagation distance in solids and liquids with a relatively large density. It can be used for ranging, industrial flaw detection, medical B-ultrasound, cleaning, welding, drilling, lithotripsy, sterilization and disinfection, etc. In this embodiment, the ultrasonic wave transmitter is an instrument for emitting ultrasonic waves to generate a vibration feeling for the user's finger. When the induction module 210 detects that the user's finger is approaching the screen page-turning area of the electronic device, the induction module 210 generates corresponding detection result information and sends the detection result information to the control module 220. In this embodiment, when the detection result information received by the control module 220 indicates that the user's finger is approaching the screen page-turning area of the electronic device, a touch simulation instruction is sent to the vibration module 230. The touch simulation instruction in this embodiment refers to an instruction that allows a touch simulation operation. That is to say, only when the vibration module 230 receives the touch simulation instruction, the vibration module 230 is allowed to send ultrasonic waves in the direction of the user's finger.

[0036] In this embodiment, the simulated touch electronic device 200 further includes:

[0037] The touch simulation module 240 is connected to the control module 220 and is configured to generate a touch simulation signal according to a touch simulation instruction received from the control module.

[0038] In this embodiment, the sensing module 210 includes an infrared sensor, which is disposed in a housing of the electronic device.

[0039] Specifically, infrared sensing uses infrared light as a medium for measurement. It can be categorized into five types based on function and, based on detection mechanism, into photon detectors and thermal detectors. Infrared emitting diodes can be driven in two ways: level-type and pulse-type. Separate photoelectric sensors consist of an array of infrared emitting diodes. The innovation of infrared sensors lies in their ability to withstand strong external light interference. Sunlight contains infrared radiation that interferes with infrared receiving diodes. This radiation can turn on the infrared receiving diodes, causing system misjudgments or even complete system failure. The advantage of infrared sensors lies in the ability to set up multi-point acquisition. The spacing and number of emitting diode arrays can be adjusted according to needs.

[0040] In this embodiment, the control module 220 includes a micro control unit for sending a touch simulation instruction to the vibration module 230 and the touch simulation module 240 when the detection result information indicates that the finger is close to the page turning area of the screen of the electronic device.

[0041] In this embodiment, the vibration module 230 includes an ultrasonic transmitter, which is configured to emit ultrasonic waves toward the user's fingers, thereby causing the user to experience tactile vibration.

[0042] Ultrasonic waves are sound waves with frequencies exceeding 20,000 Hz. In practical applications, they are divided into power ultrasonic waves and detection ultrasonic waves. They have good directionality and strong penetrating power, allowing for concentrated sound energy. They can propagate over long distances in dense solids and liquids. They are used for distance measurement, industrial flaw detection, medical B-ultrasound, cleaning, welding, drilling, stone crushing, and sterilization.

[0043] In this embodiment, the tactile simulation module 240 includes a pressure unit for applying voltage to electrodes below the screen page turning area according to a tactile simulation signal when the user touches the screen page turning area of the electronic device, thereby generating a tactile vibration sense for the user.

[0044] Specifically, in this embodiment, the tactile simulation module 240 may include an ultrasonic transmitter and a pressurization circuit. When the sensing module 210 detects that the user's finger is near the screen flipping area of the electronic device, the sensing module 210 generates corresponding detection result information and sends the detection result information to the control module 220. The control module 220 sends a tactile simulation instruction to the tactile simulation module 240 according to the received detection result information. At this time, the tactile simulation module 240 applies a voltage to the electrode under the screen flipping area of the electronic device through the pressurization circuit. This voltage is very small and does not cause harm to the human body, and it enables the user to generate a tactile vibration sensation. The solution of this embodiment can be used not only for contact-type button tactile simulation but also for non-contact-type button tactile simulation. Especially when applied to the control of virtual reality scenarios, it can give the user a very real touch experience.

[0045] In this embodiment, the tactile simulation electronic device 200 further includes a housing, a liquid crystal display screen, a memory, and a processor.

[0046] The memory in this embodiment may include synchronous dynamic random access memory and double data rate synchronous dynamic random access memory.

[0047] The liquid crystal display screen in this embodiment may include a capacitive screen and a resistive screen.

[0048] In this embodiment, the voltage range applied by the pressurization unit to the electrode under the screen flipping area is 1 - 5V.

[0049] Specifically, in the pressurization unit, when the finger of the user of the electronic device touches the screen flipping area of the electronic device, a voltage of 1 - 5V is applied to the electrode located under the screen flipping area through the pressurization unit, so as to provide the user with an experience of simulating real touch on the premise of ensuring no harm to the human body.

[0050] The beneficial effect of the second embodiment of the present invention is that by detecting whether the user's finger is near the screen flipping area and sending ultrasonic waves to the user's finger accordingly, and at the same time applying a voltage to the electrode under the screen flipping area when the user touches the screen flipping area of the electronic device, the technical problem in the prior art that the real touch experience cannot be guaranteed when reading an e-book is solved, and the technical effect of simulating real touch when the user's finger is near and touches the screen flipping area of the electronic device is achieved.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments here, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention.
