Wherein, the ultrasonic signal shielding plate 11 is disposed above a position of the terminal protection shell 10 corresponding to a position of a surface of the terminal 20 from which an ultrasonic signal is emitted, the first end 121 of the ultrasonic echo signal through hole 12 (illustrated by a dotted line in fig. 1A because the through hole is located inside the terminal protection shell 12) is disposed at a position of the terminal protection shell 10 corresponding to the microphone perforation 21 (the perforation 21 and the first end 121 are shown to overlap in fig. 1B) on the surface of the terminal 20, and the second end 122 of the ultrasonic echo signal through hole 12 is disposed at a position of the terminal protection shell 10 corresponding to a preset position of the front surface of the terminal 20; wherein,
the ultrasonic signal shielding plate 11 blocks the ultrasonic signal emitted from the terminal 20 from being emitted in a predetermined direction, and an ultrasonic echo signal of the ultrasonic signal is guided to a microphone (not shown) of the terminal through the ultrasonic echo signal through hole 12 of the terminal protective case 10.
In one embodiment, the specific location of the ultrasonic signal shielding plate 11 is associated with the terminal 20, for example, if the terminal emits an ultrasonic signal through the earpiece device 22, the ultrasonic signal shielding plate 11 is disposed on the upper edge of the hole of the protective case of the terminal reserved for the earpiece location, as shown in fig. 1B; if the terminal emits ultrasonic signals through other positions on the surface of the terminal, the ultrasonic signal shielding plate 11 is correspondingly arranged on the upper edge of the hole or the seam of the protective shell of the terminal for emitting the ultrasonic signals. In one embodiment, the direction of the ultrasonic signal shielding plate 11 may be perpendicular to the front surface of the terminal; in yet another embodiment, the direction of the ultrasonic-signal shielding plate 11 may be at an angle of less than 90 degrees to the front face of the terminal.
In an embodiment, the larger the height of the ultrasonic signal shielding plate is, the better the shielding effect on the ultrasonic signal is, and the height of the ultrasonic signal shielding plate can be increased as much as possible on the premise of not affecting the appearance shape of the terminal protection shell 10, so as to ensure better directivity of ultrasonic emission.
In one implementation, the preset position of the front surface of the terminal may be a position above the front surface of the terminal; in a further embodiment, the preset position of the front surface of the terminal can also be the position of the second end of the other front surface of the terminal where the ultrasonic echo signal through hole can be arranged.
In an embodiment, the first end 121 of the ultrasonic echo signal through hole 12 is disposed at a position corresponding to a terminal microphone, the number of the perforations corresponding to the terminal surface of the terminal microphone may be set according to an actual design requirement of the terminal, the present disclosure does not limit the number of the perforations corresponding to the terminal surface of the microphone, the present disclosure does not limit the number of the holes corresponding to the ultrasonic echo signal through hole on the outer surface of the protective case of the terminal, the number of the ultrasonic signal through holes may be the same as the number of the perforations corresponding to the terminal surface of the terminal microphone, or only one ultrasonic signal through hole may be disposed, and the ultrasonic signal through hole may penetrate through each of the microphone perforations on the terminal surface.
In this embodiment, when the ultrasonic signal transmitted by the terminal is transmitted from the surface of the terminal, the ultrasonic signal shielding plate 11 of the terminal protection case 10 can weaken the ultrasonic signal intensity of the upper side and the rear side of the terminal, and the ultrasonic echo signal through hole 12 can weaken the signal intensity of the received ultrasonic echo signal of the upper side and the rear side of the terminal, so that the terminal enhances the directivity of the transmitted ultrasonic signal and the directivity of the received ultrasonic echo signal when using the terminal protection case, and the problem that the terminal can close the touch screen due to high ultrasonic echo signal intensity when the user approaches the terminal at the rear side of the terminal can be avoided.
Fig. 2 is a perspective view of a terminal protective case according to an exemplary embodiment; in this embodiment, by using the above-mentioned terminal protection shell provided by the embodiment of the present disclosure, taking the structure of the ultrasonic echo signal through hole as an example for exemplary explanation, as shown in fig. 2, on the basis of the above-mentioned embodiments shown in fig. 1A and fig. 1B, the apparatus may further include: a signal leakage prevention spacer 13, a magnet 14; wherein, prevent that signal from revealing gasket 13 sets up in the first end of supersound echo signal through-hole 12, prevent that the size of signal reveals gasket 13 and terminal microphone are unanimous at the perforation size of terminal surface.
In an embodiment, the signal leakage prevention gasket 13 may enhance the tightness of the joint between the terminal protective shell 10 and the terminal at the perforation of the microphone on the surface of the terminal, so that the ultrasonic echo signals entering from the second segment of the ultrasonic echo signal through hole may all enter the perforation of the microphone of the terminal, thereby ensuring that all the ultrasonic echo signals which can be collected are collected by the terminal, and increasing the accuracy of preventing the terminal from being touched by mistake.
In an embodiment, the magnet 14 is disposed on the inner side surface of the terminal protection shell attached to the terminal, when the terminal is in a call, the magnetic field strength of the periphery can be determined by a hall sensor in the terminal, and if the terminal protection shell is used, the terminal can sense the magnetic field generated by the magnet 14 of the terminal protection shell. Since the energy value of the ultrasonic echo signal of the terminal using the terminal protective case 10 is lower than that of the ultrasonic echo signal without using the terminal protective case 10, in order to enhance the touch recognition sensitivity of the terminal, when the terminal determines that the terminal protective case is used through the magnet 14 of the terminal protective case, it may be determined whether to prevent a false touch using a relatively small first preset threshold value.
It will be appreciated by those skilled in the art that detection of a touch action can also be achieved by the present disclosure when the terminal is placed in a user's pocket or bag, and in such cases disabling response to the touch action.
As will be understood by those skilled in the art, the overall material of the terminal protection case is not limited in the present disclosure, for example: the gasket 13 is preferably made of rubber, or other materials with good sealing property; in another embodiment, the present disclosure does not limit the overall shape of the terminal protection case, for example: can be soft shell, hard shell, frame, wallet type, etc.
In this embodiment, the gasket for preventing signal leakage may 13 enhance the sealing property of the terminal protective shell 10 and the terminal in the fitting of the microphone in the perforation of the terminal surface, so that the ultrasonic echo signals entering from the second segment of the ultrasonic echo signal through hole may all enter the microphone perforation of the terminal, thereby ensuring that the terminal collects all the ultrasonic echo signals that can be collected, and further realizing the function of preventing accidental touch.
Fig. 3 is a flowchart illustrating a touch recognition method according to an exemplary embodiment, where, as shown in fig. 3, the touch recognition method includes the following steps:
in step 301, it is determined whether the terminal uses a terminal protection case, and if the terminal uses the terminal protection case, step 302 is performed, and if the terminal does not use the terminal protection case, step 303 is performed.
In one embodiment, whether to use the protective case of the terminal may be determined by a hall sensor built in the terminal. In step 302, it is determined whether the terminal is touched according to a first preset threshold.
In step 303, it is determined whether the terminal is touched according to a second preset threshold, where the second preset threshold is greater than the first preset threshold.
In one embodiment, the first preset threshold and the second preset threshold are used for measuring the energy value of the ultrasonic echo signal.
In an embodiment, the specific values of the first preset threshold and the second preset threshold may be empirical values, and the second preset threshold is determined by measuring a corresponding relationship between a distance between the user and the touch screen and an energy value of the ultrasonic echo signal detected by the microphone in a case where the terminal is not using the terminal protection shell, and a corresponding relationship between a distance between the user and the back of the terminal and an energy value of the ultrasonic echo signal detected by the microphone in a case where the terminal is not using the terminal protection shell, for example: when the distance between the user and the back of the terminal is 0, the ultrasonic echo signal energy value detected by the microphone is 9 joules, the larger the distance between the user and the back of the terminal is, the smaller the ultrasonic echo signal energy value detected by the microphone is, and when the distance between the user and the front of the terminal (touch screen) is 1cm, the ultrasonic echo signal energy value detected by the microphone is 9 joules, the smaller the distance between the user and the front of the terminal is, the larger the ultrasonic echo signal energy value detected by the microphone is, so that the first preset threshold value needs to be greater than 9 joules, and the situation that when the user approaches the terminal from the back side is avoided, the terminal also performs the operation of closing the screen.
In an embodiment, the first preset threshold may be determined by using a method similar to the method for determining the second preset threshold, because the energy value of the ultrasonic echo signal when the user approaches the terminal on the rear side of the terminal is small under the condition that the terminal uses the terminal protection shell, and the energy value of the ultrasonic echo signal may be 1 joule when the distance between the user and the rear side of the terminal is 0, the first preset threshold may be set to be smaller, for example, to be 5 joules, so that the distance between the user and the front side of the terminal is relatively large, for example, the screen can be turned off when the distance is 3cm, and the touch recognition sensitivity of the terminal is increased.
In an embodiment, the terminal protection case mentioned in the embodiments of the present disclosure may be the terminal protection case shown in fig. 2.
In this embodiment, whether the terminal is touched is determined by using a first preset threshold value when the terminal uses the terminal protection shell, and whether the terminal is touched is determined by using a second preset threshold value when the terminal does not use the terminal protection shell, where the second preset threshold value is greater than the first preset threshold value. Because the ultrasonic signal shielding plate of the terminal protection shell can weaken the ultrasonic signal intensity towards the upper side and the rear side of the terminal, and the ultrasonic echo signal through hole can weaken the signal intensity of the received ultrasonic echo signal at the upper side and the rear side of the terminal, the terminal enhances the directivity of the transmitted ultrasonic signal and the directivity of the received ultrasonic echo signal when the terminal protection shell is used, and the problem that the terminal can close the touch screen due to high ultrasonic echo signal intensity when the rear side of the terminal is close to the terminal can be avoided.
Fig. 4 is a flowchart illustrating a touch recognition method according to another exemplary embodiment, and this embodiment schematically illustrates the touch recognition method of the terminal on the basis of the above embodiments, and as shown in fig. 4, the touch recognition method includes the following steps:
in step 401, the hall sensor is controlled to measure the magnetic induction, and step 402 and step 404 are executed.
In step 402, if the magnetic induction is greater than a preset intensity threshold, it is determined that the terminal uses the terminal protection shell.
In step 403, it is determined whether the terminal is touched according to the first preset threshold, and the process ends.
In step 404, if the magnetic induction is greater than the preset intensity threshold, it is determined that the terminal does not use the terminal protection shell.
In step 405, it is determined whether the terminal is touched according to a second preset threshold, and the process ends.
Step 403 may specifically include the following steps:
controlling a microphone to receive an ultrasonic echo signal of an ultrasonic signal transmitted by an ultrasonic transmitter;
determining whether the energy value of the ultrasonic echo signal is greater than a first preset threshold value;
if the energy value of the ultrasonic echo signal is larger than a first preset threshold value, determining that the terminal is touched;
and if the energy value of the ultrasonic echo signal is not greater than the first preset threshold value, determining that the terminal is not touched.
Step 405 may specifically include the following steps:
controlling a microphone to receive an ultrasonic echo signal of an ultrasonic signal transmitted by an ultrasonic transmitter;

and if the energy value of the ultrasonic echo signal is not greater than a second preset threshold value, determining that the terminal is not touched.
