For example, the electronics determine a first distance between the first PZT receiver and the PZT transmitter and determine a second distance between the second PZT receiver and the PZT transmitter; determining the placement positions of the first PZT receiver and the second PZT receiver under the display screen according to the first distance and the second distance; the electronic equipment acquires the current touch operation of a user on the display screen; detecting a first signal reception intensity of a first PZT receiver and a second signal reception intensity of a second PZT receiver under a current touch operation; and the electronic equipment determines whether to start the false touch prevention mode according to the placement positions of the first PZT receiver and the second PZT receiver under the display screen and the first signal receiving intensity and the second signal receiving intensity.
For example, in the method for preventing false touch provided in the embodiment of the present application, three PZT sensors (including a PZT transmitter and two PZT receivers) arranged from top to bottom according to a preset sequence and irregular distances may be added on a certain vertical line below a display screen of an electronic device, and a schematic diagram of the arrangement position of the PZT sensors is shown in fig. 2; wherein, rx1 is the first PZT receiver, tx is the PZT transmitter, rx2 is the second PZT receiver, the part between Rx1 and Tx is the upper part of the display screen, and the part between Rx2 and Tx is the lower part of the display screen.
Wherein, tx may refer to a transmitter responsible for converting information into wireless signals and transmitting; rx may refer to a receiver that is responsible for receiving wireless signals and converting them into identifiable data or information.
In one embodiment, as shown in fig. 3, a method for preventing false touch is provided, and the method is applied to the electronic device in fig. 1 for illustration, and includes the following steps:
step S301, determining a first distance between a first PZT receiver and a PZT transmitter and determining a second distance between a second PZT receiver and the PZT transmitter.
Specifically, the electronic device detects a first distance between the first PZT receiver and the PZT transmitter and a second distance between the second PZT receiver and the PZT transmitter within the display screen.
In this embodiment, the electronic device starts timing according to the emission time of the PZT emitter at which the lamb wave is emitted, and the lamb wave propagates in the air until each PZT receiver immediately stops timing when receiving the lamb wave, at which time the first distance S1 may be calculated according to the following formula:
S1=vt
where S1 is a first distance, v is the speed of the lamb wave in the air sensor, and t is the time from when the PZT transmitter transmits the lamb wave to when the first PZT receiver receives the lamb wave.
The calculation manner of the second distance is the same as that of the first distance, and the disclosure is omitted herein.
The lamb wave is a special sound wave and has the characteristic of only propagating along the horizontal direction. In this embodiment, a PZT transmitter is used to transmit lamb waves, which are transferred in the horizontal direction to PZT receivers on the same plane to achieve a measurement of the distance between the PZT transmitter and the PZT receivers.
Step S302, the placement positions of the first PZT receiver and the second PZT receiver under the display screen are determined according to the first distance and the second distance.
Specifically, the electronic device determines the locations of the first PZT receiver and the second PZT receiver based on the first distance and the second distance.

The anti-false touch mode is one of settings in intelligent equipment (such as a smart phone, a tablet personal computer and the like) and aims to reduce false operation caused by accidental touch of a screen when a user operates the equipment; this mode is designed to enhance the user experience and avoid unnecessary operation or function switching due to false touches.
Specifically, the electronic device determines whether the first signal receiving intensity and the second signal receiving intensity exceed a preset threshold according to the positions of the first PZT receiver and the second PZT receiver, and determines whether to start the false touch preventing mode according to the determination result.
According to the false touch prevention method, the PZT transmitter and the plurality of PZT receivers are arranged below the display screen, and the distances between the PZT transmitter and each PZT receiver are determined, so that the placement positions of the PZT transmitter and each PZT receiver under the display screen can be determined, then the electronic equipment obtains the current touch operation of a user on the display screen, the electronic equipment detects the signal receiving intensity of each PZT receiver under the current touch operation, and whether the false touch prevention mode is started or not is judged according to the placement positions of the PZT transmitter and each PZT receiver under the display screen and the signal receiving intensity of each PZT receiver. The error touch prevention method is used for replacing the traditional scheme of using the optical proximity sensor to prevent error touch, can avoid being influenced by reduction of the light transmittance of the screen, and therefore the error touch prevention function of the equipment screen can be achieved, and meanwhile the cost is low.
In one embodiment, in the step S302, the positioning of the first PZT receiver and the second PZT receiver under the display screen is determined according to the first distance and the second distance, and the method specifically includes the following steps:
if the first distance is greater than the second distance, determining that the position of the first PZT receiver is at the lower half part of the display screen, and determining that the position of the second PZT receiver is at the upper half part of the display screen; if the first distance is less than the second distance, the position of the first PZT receiver is determined to be in the upper half of the display screen, and the position of the second PZT receiver is determined to be in the lower half of the display screen.
Specifically, the electronic device judges the magnitude relation between the first distance and the second distance, and determines that the position of the first PZT receiver is at the lower half part of the display screen and the position of the second PZT receiver is at the upper half part of the display screen when recognizing that the first distance is greater than the second distance; and in the case that the first distance is recognized to be smaller than the second distance, determining that the position of the first PZT receiver is in the upper half of the display screen, and the position of the second PZT receiver is in the lower half of the display screen.
In this embodiment, by determining the magnitude relation between the first distance and the second distance, two situations of different placement positions of the first PZT receiver and the second PZT receiver are accurately distinguished according to the determination result, so that the practicality and accuracy of the scheme are increased.
In one embodiment, as shown in fig. 4, in the step S304, the detection of the first signal receiving intensity of the first PZT receiver and the second signal receiving intensity of the second PZT receiver in the current touch operation specifically includes the following steps:

Step S403, determining a first signal reception intensity of the first PZT receiver and a second signal reception intensity of the second PZT receiver according to the guided wave reception frequency.
Wherein, guided wave refers to the phenomenon that electromagnetic waves (such as light waves or microwaves) propagate along a specific path in a certain medium or structure; different types of guided waves have different characteristics and applications, the following are several common guided waves: optical guided waves, microwave guided waves, lamb waves, and the like.
Specifically, the electronic device detects the guided wave wavelength received by the first PZT receiver and the second PZT receiver in a unit time; according to the unit time and the guided wave wavelength, the guided wave receiving frequency is calculated by a preset operation model; a first signal reception intensity of the first PZT receiver and a second signal reception intensity of the second PZT receiver are determined according to the guided wave reception frequency.
In the embodiment, the guided wave receiving frequency is obtained by detecting the guided wave wavelength received by the first PZT receiver and the second PZT receiver in unit time and according to the unit time and the guided wave wavelength; thus, the signal receiving intensities of the first PZT receiver and the second PZT receiver are accurately determined, and an effective scheme for detecting the signal receiving intensity by utilizing the physical parameter of the guided wave wavelength is realized.
In one embodiment, in the step S304, the method detects the first signal receiving intensity of the first PZT receiver and the second signal receiving intensity of the second PZT receiver in the current touch operation, and further includes the steps of:
detecting the number of multipaths received by the first PZT receiver and the second PZT receiver in a unit time; a first signal reception strength of the first PZT receiver and a second signal reception strength of the second PZT receiver are determined based on the number of multipaths received per unit time.
Wherein multipath refers to the phenomenon that a signal undergoes multiple paths to reach a receiver in the propagation process; this phenomenon is commonly found in wireless communication and mobile communication, particularly in urban environments or in places where there are obstacles.
Specifically, the electronic device detects the number of multipaths received by the first PZT receiver and the second PZT receiver in a unit time; the signal reception strengths of the first PZT receiver and the second PZT receiver are determined based on the number of multipaths received per unit time.
In this embodiment, the number of multipaths received by the first PZT receiver and the second PZT receiver in a unit time is detected; thus, the signal receiving intensities of the first PZT receiver and the second PZT receiver are accurately determined, and an effective scheme for detecting the signal receiving intensity by utilizing the parameter index of the multipath quantity is realized.
In one embodiment, in the step S305, it is determined whether to start the anti-false touch mode according to the positions of the first PZT receiver and the second PZT receiver, the first signal receiving strength, and the second signal receiving strength, and the method specifically includes the following steps:
if the placement position of the first PZT receiver under the display screen is at the upper half part of the display screen, the placement position of the second PZT receiver under the display screen is at the lower half part of the display screen, judging whether the first signal receiving intensity and the second signal receiving intensity exceed a preset threshold value, and if the first signal receiving intensity exceeds the preset threshold value and the second signal receiving intensity does not exceed the preset threshold value, determining to start an anti-false touch mode; if the placement position of the first PZT receiver under the display screen is at the lower half part of the display screen, the placement position of the second PZT receiver under the display screen is at the upper half part of the display screen, judging whether the first signal receiving intensity and the second signal receiving intensity exceed a preset threshold value, and if the first signal receiving intensity does not exceed the preset threshold value and the second signal receiving intensity exceeds the preset threshold value, determining to start an anti-false touch mode; and if the first signal receiving intensity and the first signal receiving intensity do not exceed the preset threshold value, determining that the false touch preventing mode is not started.
The preset threshold value refers to a threshold value of signal intensity, and is used for judging whether the signal intensity meets a preset numerical condition.
Specifically, if the position of the first PZT receiver is at the upper half part of the display screen, and the position of the second PZT receiver is at the lower half part of the display screen, the electronic device determines to enable the anti-false touch mode when recognizing that the first signal receiving intensity exceeds the preset threshold value and the second signal receiving intensity does not exceed the preset threshold value; if the position of the first PZT receiver is at the lower half part of the display screen, the position of the second PZT receiver is at the upper half part of the display screen, the electronic equipment determines to start the anti-false touch mode under the condition that the first signal receiving intensity and the second signal receiving intensity are identified whether to exceed a preset threshold value or not, and if the first signal receiving intensity does not exceed the preset threshold value and the second signal receiving intensity exceeds the preset threshold value; if the first signal receiving intensity and the first signal receiving intensity do not exceed the preset threshold, the electronic equipment determines that the anti-false touch mode is not started.
In this embodiment, based on two situations that the placement positions of the first PZT receiver and the second PZT receiver under the display screen are different, whether the first signal receiving intensity and the second signal receiving intensity exceed a preset threshold value is respectively determined; therefore, whether the anti-false touch mode is started or not is determined in a targeted manner according to the judgment result of the signal receiving intensity, and meanwhile, the practicability and the flexibility of the scheme are improved.
In one embodiment, after the current touch operation of the user on the display screen is obtained, the method further includes the following steps:
and according to the capacitance effect, determining whether the touch position of the current touch operation coincides with the position of any PZT sensor.
Wherein, the capacitance effect refers to the phenomenon that when a voltage difference exists between two conductors, an electric field is generated between the two conductors, and charges are stored under the action of the electric field; this ability to store charge is known as capacitance, and the electric field between conductors and the amount of charge stored is related to the size of the capacitance.
Specifically, the electronic equipment detects signal change values of all PZT sensors according to capacitance effects, and compares the signal change values with signal change thresholds; under the condition that the signal change value of any PZT sensor exceeds a signal change threshold value, determining a target PZT sensor overlapped with the touch position; when the signal change value of any PZT sensor is not detected to exceed the signal change threshold value, confirming that the touch position is not overlapped with the position of each PZT sensor.
In this embodiment, the signal variation value of each PZT sensor is detected according to the capacitance effect, and compared with the signal variation threshold; therefore, whether the touch position is overlapped with the position of each PZT sensor or not is accurately detected, and the target PZT sensor overlapped with the touch position is identified.
