All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the disclosure, which is not described in detail in the embodiments of the present invention.
The embodiment of the invention provides a method for closing a terminal screen, which comprises the steps of obtaining a first distance from a first position of a terminal to a user and a second distance from a second position of the terminal to the user, and determining whether to close the terminal screen according to the first distance and the second distance, wherein the first position is close to the top of the terminal, and the second position is close to the bottom of the terminal. Referring to fig. 2, the method includes:
step 201: and detecting whether the terminal is in a call state currently.
Wherein, when the terminal is currently in a call state, step 202 is executed; and when the terminal is not in the call state currently, ending the operation.
Step 202: when the terminal is in a call state at present, a first distance is acquired through a first distance sensor.
When the terminal is in a call state, the terminal may turn on a first distance sensor provided at a first position of the terminal, and transmit a signal through a signal transmitting device included in the first distance sensor. When the signal meets an obstacle, the obstacle reflects all or part of the signal, wherein the obstacle is usually a user who makes a call when the terminal is in a call state. The terminal receives the reflected signal through a signal receiving device included in the first distance sensor, obtains first transmission time from transmitting to receiving of the signal according to transmitting time of the first distance sensor for transmitting the signal and receiving time of the first distance sensor for receiving the reflected signal, and obtains a first distance from the terminal to a user through conversion according to the first transmission time and the transmission rate of the signal.
It should be noted that the first position is a position where a distance from the terminal to the top of the terminal does not exceed a preset first threshold, where the preset first threshold may be a distance threshold preset by the terminal, for example, when the preset first threshold is 1.5 cm, the first position is any position 1.5 cm away from the top of the terminal, and accordingly, the first distance sensor is a distance sensor disposed at the first position 1.5 cm away from the top of the terminal, and of course, the first position may also be any position 1 cm or 0.5 cm away from the top of the terminal, which is not limited in this embodiment of the present invention.
In addition, the method for obtaining the first distance from the terminal to the user by conversion according to the first transmission time and the transmission rate of the signal is as follows: and calculating the time difference between the receiving time of the first distance sensor for receiving the reflected signal and the transmitting time of the first distance sensor for transmitting the signal, and multiplying half of the time difference by the transmission rate of the signal to obtain the first distance from the terminal to the user.
Step 203: and judging whether the first distance exceeds a preset second threshold value.
When the first distance exceeds a preset second threshold, executing step 204; and when the first distance does not exceed a preset second threshold, closing the terminal screen.
When the first distance exceeds the preset second threshold, it indicates that the top of the terminal is far from the user, and at this time, the terminal may be far from the user, and the user may still need to operate the terminal during a call, or the bottom of the terminal is close to the user, so that the distance from the bottom of the terminal to the user needs to be further determined through the following step 204.
When the first distance is not more than the preset second threshold, it indicates that the top of the terminal is closer to the user, for example, the top speaker of the terminal is close to the ear of the user, and at this time, the user does not need to operate the terminal and does not need to keep the terminal screen in a lighting state, so that the terminal screen can be turned off.
Step 204: and when the first distance exceeds a preset second threshold value, acquiring a second distance through a second distance sensor.
When the first distance exceeds a preset second threshold, the terminal may turn on a second distance sensor provided at a second position of the terminal, and transmit a signal through a signal transmitting device included in the second distance sensor. When the signal meets an obstacle, the obstacle reflects all or part of the signal, wherein the obstacle is usually a user who makes a call when the terminal is in a call state. The terminal receives the reflected signal through a signal receiving device included by the second distance sensor, obtains second transmission time from transmitting to receiving of the signal according to transmitting time of the signal transmitted by the second distance sensor and receiving time of the reflected signal received by the second distance sensor, and obtains a second distance from the terminal to the user through conversion according to the second transmission time and the transmission rate of the signal.
It should be noted that the second position is a position where a distance from the terminal to the top of the terminal does not exceed a preset first threshold, for example, when the preset first threshold is 1.5 cm, the second position is any position 1.5 cm away from the bottom of the terminal, and correspondingly, the second distance sensor is a distance sensor disposed at a second position 1.5 cm away from the bottom of the terminal, of course, the second position may also be any position 1 cm away from the bottom of the terminal, or 0.5 cm away from the bottom of the terminal, and this is not limited in this embodiment of the present invention.
In addition, the method for obtaining the second distance from the terminal to the user by conversion according to the second transmission time and the transmission rate of the signal is as follows: and calculating the time difference between the receiving time of the second distance sensor for receiving the reflected signal and the transmitting time of the second distance sensor for transmitting the signal, and multiplying half of the time difference by the transmission rate of the signal to obtain the second distance from the terminal to the user.
Step 205: and judging whether the second distance exceeds a preset third threshold value.
When the second distance exceeds a preset third threshold, ending the operation; when the second distance does not exceed the preset third threshold, step 206 is executed.
When the second distance exceeds the preset third threshold, the distance from the bottom of the terminal to the user is far, and since the top of the terminal is judged to be far from the user in the steps, the whole terminal can be determined to be far from the user at this time, and the user may need to operate the terminal during the call, so that the subsequent operation of closing the terminal screen is not executed, and the steps of the method are ended.
When the second distance does not exceed the preset third threshold, it indicates that the bottom of the terminal is closer to the user, for example, the bottom microphone of the terminal is close to the mouth of the user, as shown in fig. 3, at this time, the user does not need to operate the terminal, and the terminal screen does not need to keep on a lighting state, so that the subsequent operation of closing the terminal screen can be continuously performed.
It should be noted that the preset second threshold and the preset third threshold may be two distance thresholds preset by the terminal, and the two distance thresholds may be equal or unequal. For example, the preset second threshold may be 2 centimeters, the preset third threshold may be 1.8 centimeters, or both the preset second threshold and the preset third threshold may be 2 centimeters or 1.8 centimeters, which is not limited in the embodiment of the present invention.
Step 206: and when the second distance does not exceed a preset third threshold value, closing the terminal screen.
It should be noted that, in the embodiment of the present invention, the first distance sensor or the second distance sensor may be installed at the first position or the second position of the terminal in the manner as shown in fig. 4, that is, a first or second distance sensor is mounted on the printed circuit board at a first or second location of the terminal, the first distance sensor or the second distance sensor comprises a signal receiving device and a signal transmitting device, a rubber pad is arranged between the first distance sensor or the second distance sensor and the terminal screen, the rubber pad is used for preventing the first distance sensor or the second distance sensor, and the terminal screen from being worn, of course, in practical applications, the installation manner of the first distance sensor or the second distance sensor at the first position or the second position of the terminal may be other manners, and this is not specifically limited in the embodiment of the present invention.
In addition, the signal emitting devices of the first distance sensor and the second distance sensor may be infrared light emitting diodes, and accordingly, the signal emitted by the signal emitting device may be infrared light, for example, the signal emitted by the signal emitting device is infrared light with a wavelength of 850 nanometers or 940 nanometers, and the signal receiving devices of the first distance sensor and the second distance sensor may be infrared light receivers, which is not specifically limited in this embodiment of the present invention.
Furthermore, in the embodiment of the present invention, the terminal may obtain the first distance and the second distance from the terminal to the user through two distance sensors respectively disposed at the first position and the second position, and of course, in practical applications, the terminal may also obtain the first distance and the second distance through other manners, which is not specifically limited in the embodiment of the present invention.
Optionally, in the embodiment of the present invention, a second distance from the second position of the terminal to the user may be obtained by the second distance sensor, when the second distance exceeds a preset third threshold, a first distance from the first position of the terminal to the user is obtained by the first distance sensor, and when the first distance does not exceed the preset second threshold, the terminal screen is closed. Or,
a first distance from a first position of the terminal to a user can be acquired through the first distance sensor, a second distance from a second position of the terminal to the user is acquired through the second distance sensor, and when the first distance does not exceed a preset second threshold value and/or the second distance does not exceed a preset third threshold value, a terminal screen is closed.
In the embodiment of the invention, the terminal firstly detects whether the terminal is in a call state at present, if the terminal is in the call state at present, whether a first distance acquired at a first position of the terminal exceeds a preset second threshold and/or whether a second distance acquired at a second position of the terminal exceeds a preset third threshold is judged, and when the first distance does not exceed the preset second threshold and/or the second distance does not exceed the preset third threshold, a terminal screen is closed. According to the embodiment of the invention, the terminal screen can be closed by determining that the first distance acquired at the first position of the terminal does not exceed the preset second threshold and/or the second distance acquired at the second position of the terminal does not exceed the preset third threshold, and the terminal can accurately determine the distance between the user and the terminal through the first distance and the second distance acquired at the two positions because a certain distance exists between the first position and the second position.
The embodiment of the invention provides a method for closing a terminal screen, which comprises the steps of acquiring first reflection signal intensity corresponding to a signal emitted at a first position of a terminal and second reflection signal intensity corresponding to a signal emitted at a second position of the terminal, and determining whether to close the terminal screen or not according to the first reflection signal intensity and the second reflection signal intensity, wherein the first position is close to the top of the terminal, and the second position is close to the bottom of the terminal. Referring to fig. 5, the method includes:
step 501: and detecting whether the terminal is in a call state currently.
Wherein, when the terminal is currently in a call state, step 502 is executed; and when the terminal is not in the call state currently, ending the operation.
Step 502: when the terminal is in a call state at present, the strength of the first reflection signal is obtained through the first strength sensor.
When the terminal is in a call state, the terminal may turn on a first intensity sensor provided at a first position of the terminal, and transmit a signal through a signal transmitting device of the first intensity sensor itself. When the signal meets an obstacle, the obstacle reflects a first reflected signal, wherein the first reflected signal is all or part of the signal, and the obstacle is usually a user who makes a call when the terminal is in a call state. The terminal receives the first reflected signal reflected back through a signal receiving device included in the first intensity sensor, and detects the intensity of the first reflected signal.
It should be noted that the first position is a position where a distance from the terminal to the top of the terminal does not exceed a preset first threshold, where the preset first threshold may be a distance threshold preset by the terminal, for example, when the preset first threshold is 1.5 cm, the first position is any position 1.5 cm away from the top of the terminal, and accordingly, the first distance sensor is a distance sensor disposed at the first position 1.5 cm away from the top of the terminal, and of course, the first position may also be any position 1 cm or 0.5 cm away from the top of the terminal, which is not limited in this embodiment of the present invention.
Step 503: and judging whether the intensity of the first reflected signal exceeds a preset second threshold value.
When the intensity of the first reflected signal does not exceed the preset second threshold, step 304 is executed; and when the strength of the first reflected signal exceeds a preset second threshold, closing the terminal screen.
The magnitude of the first reflected signal strength is in inverse proportion to a first distance from the first location of the terminal to the user, so that when the first reflected signal strength does not exceed a preset second threshold, it indicates that the top of the terminal is far away from the user, at this time, the terminal may be far away from the user, and the user may still need to operate the terminal during a call, or the bottom of the terminal is close to the user, so that the distance from the bottom of the terminal to the user needs to be further determined through the following step 504.
When the first reflected signal strength exceeds the preset second threshold, the fact that the top of the terminal is close to the user is indicated, for example, a loudspeaker at the top of the terminal is close to the ear of the user, the user does not need to operate the terminal at the moment, the terminal screen does not need to be kept in a lighting state, and therefore the terminal screen can be closed.
Step 504: and when the intensity of the first reflected signal does not exceed a preset second threshold value, acquiring the intensity of a second reflected signal through a second intensity sensor.
When the intensity of the first reflected signal does not exceed the preset second threshold, the terminal may turn on a second intensity sensor disposed at a second position of the terminal, and transmit a signal through a signal transmitting device of the second intensity sensor itself. When the signal meets an obstacle, the obstacle reflects a second reflected signal, wherein the second reflected signal is all or part of the signal, and the obstacle is usually a user who makes a call when the terminal is in a call state. The terminal receives the reflected second reflected signal through a signal receiving device included in the second intensity sensor, and detects the intensity of the second reflected signal.
It should be noted that the second position is a position where a distance from the terminal to the top of the terminal does not exceed a preset first threshold, for example, when the preset first threshold is 1.5 cm, the second position is any position 1.5 cm away from the bottom of the terminal, and correspondingly, the second distance sensor is a distance sensor disposed at a second position 1.5 cm away from the bottom of the terminal, of course, the second position may also be any position 1 cm away from the bottom of the terminal, or 0.5 cm away from the bottom of the terminal, and this is not limited in this embodiment of the present invention.
Step 505: and judging whether the intensity of the second reflected signal exceeds a preset third threshold value.
When the intensity of the second reflected signal does not exceed a preset third threshold, ending the operation; when the second reflected signal strength exceeds the preset third threshold, step 506 is executed.
The magnitude of the second reflected signal strength is in inverse proportion to a second distance from the second position of the terminal to the user, so that when the second reflected signal strength does not exceed a preset third threshold value, the bottom of the terminal is far away from the user, and since the top of the terminal is judged to be far away from the user in the steps, the whole terminal can be determined to be far away from the user at the moment, the user may need to operate the terminal during conversation, and therefore, the subsequent operation of closing the terminal screen is not executed, namely, the steps of the method are finished.
When the second reflected signal strength exceeds the preset third threshold, it indicates that the bottom of the terminal is closer to the user, for example, the bottom microphone of the terminal is close to the mouth of the user, as shown in fig. 3, at this time, the user does not need to operate the terminal, and the terminal screen does not need to be kept in a lighting state, so that the subsequent operation of closing the terminal screen can be continuously performed.
It should be noted that the preset second threshold and the preset third threshold may be two intensity thresholds preset by the terminal, and the two intensity thresholds may be equal or unequal. For example, the preset second threshold may be 4 candelas, the preset third threshold may be 3 candelas, or both the preset second threshold and the preset third threshold may be 4 candelas or 3 candelas, which is not limited in the embodiment of the present invention.
Step 506: and when the strength of the second reflected signal exceeds a preset third threshold value, closing the terminal screen.

In addition, the signal emitting devices of the first intensity sensor and the second intensity sensor may be infrared light emitting diodes, and accordingly, the signal emitted by the signal emitting device may be infrared light, for example, the signal emitted by the signal emitting device is infrared light with a wavelength of 850 nanometers or 940 nanometers, and the signal receiving devices of the first distance sensor and the second distance sensor may be infrared light receivers, which is not specifically limited in this embodiment of the present invention.
Furthermore, in the embodiment of the present invention, the terminal may obtain the first reflected signal strength and the second reflected signal strength through two strength sensors respectively disposed at the first position and the second position, and certainly, in practical applications, the terminal may also obtain the first reflected signal strength and the second reflected signal strength through other manners, which is not specifically limited in this embodiment of the present invention.

Or,
the first reflected signal strength can be obtained through the first strength sensor, the second reflected signal strength is obtained through the second strength sensor, and when the first reflected signal strength exceeds a preset second threshold value and/or the second reflected signal strength exceeds a preset third threshold value, the terminal screen is closed.
