In order to facilitate understanding of the embodiments of the present invention, a communication network system on which the mobile terminal of the present invention is based is described below.

Referring to fig. 2, fig. 2 is an architecture diagram of a communication Network system according to an embodiment of the present invention, where the communication Network system is an LTE system of a universal mobile telecommunications technology, and the LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and an IP service 204 of an operator, which are in communication connection in sequence.

The E-UTRAN202 includes eNodeB2021 and other eNodeBs 2022, among others. Among them, the eNodeB2021 may be connected with other eNodeB2022 through backhaul (e.g., X2 interface), the eNodeB2021 is connected to the EPC203, and the eNodeB2021 may provide the UE201 access to the EPC 203.

Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.

Based on the above terminal hardware structure and communication network system, various embodiments of the method for controlling a mobile terminal of the present invention are proposed.

The invention provides a method for controlling a mobile terminal.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for controlling a mobile terminal according to a preferred embodiment of the present invention.

In the present embodiment, an embodiment of a method of controlling a mobile terminal is provided, it should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that here.

In this embodiment, the method for controlling a mobile terminal may be optionally applied to the mobile terminal, and the method for controlling the mobile terminal includes:

step S10, when detecting the electric signal triggered by the mobile terminal, triggering a first ultrasonic signal in the screen of the mobile terminal through the electric signal based on the electroacoustic transducer attached to the screen of the mobile terminal.

When the mobile terminal needs to start the approach sensing function, an electric signal is sent to the electroacoustic transducer. In order to avoid that the transmitted electrical signal causes interference to the user, the electrical signal is a high frequency electrical signal having a frequency of more than 20 KHz. When the frequency of a certain signal is more than 20KHz, the signal is an ultrasonic signal and cannot be heard by a user. An electroacoustic transducer in a mobile terminal is attached in the mobile terminal screen. After the mobile terminal triggers the electric signal, a first ultrasonic signal is triggered in the screen through the electric signal based on an electroacoustic transducer attached in the screen.

It should be noted that the Application program of the mobile terminal may initiate the proximity sensing function by calling a specific API (Application Programming Interface).

Furthermore, the ultrasonic receiving device is a microphone of the mobile terminal, and the electroacoustic transducer is a piezoelectric ceramic piece.

Further, the ultrasonic receiving device is a microphone of the mobile terminal, i.e. the ultrasonic receiving device is integrated in the microphone of the mobile terminal. When there are two or more microphones in the mobile terminal, all the microphones in the mobile terminal may be used as the ultrasonic wave receiving means, or one of the microphones may be designated as the ultrasonic wave receiving means. When a plurality of microphones in the mobile terminal are all used as the ultrasonic wave receiving means, a main ultrasonic wave receiving means and a sub ultrasonic wave receiving means may be provided as shown in fig. 4. It is to be understood that the ultrasonic wave receiving device may be separately provided in the mobile terminal. It should be noted that, when a plurality of microphones of the mobile terminal are all used as the ultrasonic receiving devices, the mobile terminal may determine an operation gesture of the user through the plurality of ultrasonic receiving devices, and implement intelligent control through the operation gesture, and at this time, the hand of the user is an obstacle.

An electroacoustic transducer is a device for converting electrical (acoustic) signal energy into corresponding acoustic (electrical) signal energy, and for a transducer for converting electrical energy into acoustic energy, an electrical signal is converted into mechanical vibration, and then sound waves are generated by the mechanical vibration; for a transducer that converts acoustic energy into electrical energy, an acoustic signal is converted into mechanical vibration and then into an electrical signal. In this embodiment, the electroacoustic transducer is a piezoelectric ceramic piece, which is an electronic sound component, a piezoelectric ceramic dielectric material is placed between two copper circular electrodes, and when an ac audio signal is connected to the two electrodes, the piezoelectric piece vibrates according to the magnitude and frequency of the signal to generate a corresponding sound. In other embodiments, the electro-acoustic transducer may also implement other devices that convert electrical energy into acoustic energy.

Further, step S10 includes:

step a, after detecting an electric signal triggered by the mobile terminal, converting the electric signal into mechanical vibration through an electroacoustic transducer attached to a screen of the mobile terminal.

And b, conducting mechanical vibration into the screen to trigger the first ultrasonic signal in the screen.

Further, when the mobile terminal triggers an electrical signal, an electrical energy transducer attached to the screen of the mobile terminal receives the electrical signal and converts the electrical signal into mechanical vibration. It will be appreciated that since the electroacoustic transducer is attached in the screen, when an electrical signal is converted by the electroacoustic transducer into mechanical vibration, the mechanical vibration may be conducted into the screen, generating vibration in the screen, triggering the first ultrasonic signal. It can be understood that, because the area of the screen of the mobile terminal is large, the intensity of the first ultrasonic signal triggered by the screen of the mobile terminal is large.

In step S20, a second ultrasonic signal returned after the first ultrasonic signal meets the obstacle is received by the ultrasonic receiving device in the mobile terminal.

When the mobile terminal triggers the first ultrasonic signal through the screen of the mobile terminal, the first ultrasonic signal returns when meeting an obstacle. In this embodiment, an ultrasonic signal returned after the first ultrasonic signal encounters an obstacle is referred to as a second ultrasonic signal. When the first ultrasonic signal meets an obstacle and returns to the ultrasonic signal, the second ultrasonic signal is received by the ultrasonic receiving device of the mobile terminal.

Note that, in the present embodiment, the mobile terminal functions as both the ultrasonic wave transmission device (i.e., the screen) and the ultrasonic wave reception device. In the process of moving the mobile terminal relative to the obstacle, the screen of the mobile terminal also moves relative to the obstacle. According to the doppler effect, when the mobile terminal moves relative to the obstacle, if the mobile terminal and the obstacle are close to each other, the ultrasonic signal is compressed, the wavelength of the ultrasonic signal becomes shorter, the frequency becomes higher, and a blue shift phenomenon is generated; if the mobile terminal and the obstacle are far away from each other, the opposite effect is generated, the wavelength of the ultrasonic wave signal becomes longer, and the frequency becomes lower, i.e., the red shift phenomenon is generated. It should be noted that the higher the speed of the relative movement between the mobile terminal and the obstacle, the greater the blue shift or red shift effect. It can be understood that the movement of the mobile terminal relative to the obstacle in the embodiment is essentially the process of the user taking up the mobile terminal to approach or depart from the human body during the use of the mobile terminal.

In step S30, the mobile terminal is controlled according to the attribute values corresponding to the first ultrasonic signal and the second ultrasonic signal based on the application program running in the mobile terminal.

And after the mobile terminal receives the second ultrasonic signal through the ultrasonic receiving device, the mobile terminal determines the application program currently running in the foreground, determines the attribute values corresponding to the first ultrasonic signal and the second ultrasonic signal, and realizes control operation according to the application program currently running in the foreground and the attribute values corresponding to the first ultrasonic signal and the second ultrasonic signal. The property values corresponding to the first ultrasonic signal include, but are not limited to, a fundamental frequency and a transmission amplitude, and the property values corresponding to the second ultrasonic signal include, but are not limited to, a frequency variation range and a reception amplitude. If the application program currently running in the foreground of the mobile terminal is a music player, the mobile terminal can adjust the volume according to the attribute values corresponding to the first ultrasonic signal and the second ultrasonic signal; if the application program currently running in the foreground of the mobile terminal is a character reader, the mobile terminal can adjust the size of the currently displayed characters or adjust the brightness of a screen according to the attribute values corresponding to the first ultrasonic signal and the second ultrasonic signal.

In the embodiment, after an electric signal triggered by the mobile terminal is detected, a first ultrasonic signal is triggered in the screen of the mobile terminal through the electric signal based on an electroacoustic transducer attached to the screen of the mobile terminal; receiving a second ultrasonic signal returned after the first ultrasonic signal meets an obstacle by an ultrasonic receiving device in the mobile terminal; and controlling the mobile terminal according to the attribute values corresponding to the first ultrasonic signal and the second ultrasonic signal based on the application program running in the mobile terminal. The ultrasonic signal with high intensity is sent through the screen of the mobile terminal, so that the mobile terminal is controlled according to the ultrasonic signal with high intensity and the application program which moves in the foreground at present, and the ultrasonic signal is sent through the earphone of the mobile terminal, so that the mobile terminal can be remotely controlled by sending the ultrasonic signal through the screen.

Further, a second embodiment of the method of controlling a mobile terminal of the present invention is proposed based on the first embodiment. The second embodiment of the method of controlling a mobile terminal is different from the first embodiment of the method of controlling a mobile terminal in that, referring to fig. 5, step S30 includes:

in step S31, a transmission amplitude corresponding to the first ultrasonic signal and a reception amplitude corresponding to the second ultrasonic signal are determined.

In step S32, an amplitude difference between the transmission amplitude and the reception amplitude is calculated.

Step S33, calculating the amplitude change rate according to the amplitude difference calculated at different time points;

and when the mobile terminal receives the second ultrasonic signal through the ultrasonic receiving device, the mobile terminal determines the sending amplitude corresponding to the first ultrasonic signal and the receiving amplitude corresponding to the second ultrasonic signal. After determining the transmitting amplitude and the receiving amplitude, the mobile terminal calculates an amplitude difference between the transmitting amplitude and the receiving amplitude. It can be understood that, in the relative movement process of the mobile terminal and the obstacle, the mobile terminal calculates the amplitude difference corresponding to different time points, so as to obtain a plurality of amplitude differences, and the amplitude change rate of the ultrasonic signal can be calculated through the amplitude differences. After obtaining the plurality of amplitude differences, the mobile terminal can select a preset number of amplitude differences from the calculated amplitude differences to calculate the amplitude change rate in the process of calculating the amplitude change rate. The preset number can be set according to specific needs, and is not limited herein. It should be noted that, when the mobile terminal transmits the ultrasonic signal through the ultrasonic transmitting device and receives the ultrasonic signal through the ultrasonic receiving device, the mobile terminal records the transmission amplitude of the transmitted ultrasonic signal and the reception amplitude of the received ultrasonic signal.

And step S34, controlling the mobile terminal according to the amplitude change rate based on the application program running in the mobile terminal.

And after the mobile terminal calculates the amplitude change rate, the mobile terminal realizes control operation according to the application program currently running in the foreground and the calculated amplitude change rate.

Further, step S34 includes:

and c, determining the movement trend of the mobile terminal relative to the obstacle according to the amplitude change rate.

And d, determining a corresponding operation instruction according to the application program and the motion trend of the mobile terminal in operation, and controlling the mobile terminal according to the operation instruction.

Further, after the mobile terminal calculates the amplitude change rate, the mobile terminal determines the movement trend of the mobile terminal relative to the obstacle according to the amplitude change rate, determines the application program running in the foreground, determines the corresponding operation instruction according to the running application program and the movement trend, and realizes control operation according to the operation instruction. It should be noted that, in the mobile terminal, a mapping table among the application program, the movement trend, and the operation instruction has been stored in advance. Based on the mapping table, the corresponding operation instruction can be determined through the application program and the movement trend. For example, in the mapping table, when the application program is a PDF (Portable Document Format) reader, the mobile terminal approaches an obstacle, and the corresponding operation instruction is to increase the font of the content displayed by the PDF reader; and when the mobile terminal is far away from the barrier, the corresponding operation instruction is to reduce the font of the content displayed by the PDF reader. The specific increasing and decreasing amplitudes of the fonts can be set according to specific needs, and are not limited herein.

Further, step c comprises:

and step c1, determining the change trend of the amplitude change rate.

And c2, confirming that the mobile terminal approaches the obstacle if the amplitude change rate is increased.

And c3, if the amplitude change rate is reduced, confirming that the mobile terminal is far away from the obstacle.

Further, the process of determining the movement trend of the mobile terminal relative to the obstacle according to the amplitude change rate is as follows: and after the amplitude change rate is obtained through calculation, the mobile terminal determines the change trend of the amplitude change rate. If the amplitude change rate is increased, the mobile terminal confirms that the mobile terminal approaches the obstacle, namely the mobile terminal moves towards the obstacle relative to the movement trend of the obstacle; if the amplitude change rate is reduced, the mobile terminal confirms that the mobile terminal is far away from the obstacle, namely the movement trend of the mobile terminal relative to the obstacle is far movement. Specifically, referring to fig. 6, fig. 6 is a schematic diagram illustrating the mobile terminal approaching to and moving away from an obstacle according to an embodiment of the present invention.

Further, in order to improve the accuracy of determining the movement trend of the mobile terminal relative to the obstacle, the following steps may be provided: when the amplitude change rate is increased and the increased amplitude is larger than the preset amplitude, the mobile terminal determines that the mobile terminal approaches the obstacle; when the amplitude change rate is reduced and the reduction amplitude is greater than the preset amplitude, the mobile terminal determines that the mobile terminal is far away from the obstacle. The preset amplitude can be set according to specific needs, and is not limited herein.

Further, step d includes:

and d1, if the application program being run by the mobile terminal is a call application program and the mobile terminal approaches an obstacle, determining that the corresponding operation instruction is a screen control instruction.

And d2, controlling the screen of the mobile terminal to enter a black screen state from a bright screen state according to the screen control instruction.

Further, determining a corresponding operation instruction according to the application program and the motion trend of the mobile terminal, and controlling the mobile terminal according to the operation instruction comprises the following steps: when the mobile terminal determines that the application program running on the foreground is a call application program and the mobile terminal approaches an obstacle, the mobile terminal determines that the corresponding operation instruction is a screen control instruction, and controls the screen of the mobile terminal to enter a black screen state from a bright screen state according to the determined screen control instruction.

Further, when the mobile terminal determines that the application program running on the foreground is a call application program and is far away from the obstacle, the mobile terminal determines that the corresponding operation instruction is another screen control instruction, and controls the screen to enter a bright screen state from a black screen state according to the determined another screen control instruction.

It can be understood that when the mobile terminal is in a call state, the mobile terminal approaches an obstacle and controls the screen of the mobile terminal to be in a screen-off state; the mobile terminal is far away from the barrier, and the screen of the mobile terminal is controlled to be in a bright screen state. The state of the screen of the mobile terminal is remotely controlled when the mobile terminal is in a call state through the ultrasonic signal triggered by the screen of the mobile terminal.

In the embodiment, the sending amplitude corresponding to the first ultrasonic signal and the receiving amplitude corresponding to the second ultrasonic signal are determined; calculating an amplitude difference between the transmit amplitude and the receive amplitude; calculating the amplitude change rate according to the amplitude difference calculated at different time points; and controlling the mobile terminal according to the amplitude change rate based on the application program running in the mobile terminal. The intelligent control of the mobile terminal is realized through the amplitude change rate corresponding to the ultrasonic signals.

Further, a third embodiment of the method of controlling a mobile terminal of the present invention is presented. The third embodiment of the method of controlling a mobile terminal is different from the first or second embodiment of the method of controlling a mobile terminal in that, referring to fig. 7, the step S30 further includes:

in step S35, the fundamental frequency of the first ultrasonic signal and the frequency variation range of the second ultrasonic signal are determined.

The mobile terminal determines the fundamental frequency of the first ultrasonic signal and the frequency variation range of the second ultrasonic signal received by the ultrasonic receiving device. The ultrasonic wave is a sound wave with a frequency greater than 20KHz, so that the frequency of the ultrasonic wave signal triggered by the screen of the mobile terminal should also be a certain frequency greater than 20KHz, such as 40KHz, and the certain frequency greater than 20KHz is the fundamental frequency of the first ultrasonic wave signal. In this embodiment, the variation range of the moving speed when most users use the mobile terminal, such as 0.2-20 m/s (meters per second) or 0.085-17 m/s, can be determined through a finite number of tests, that is, the speed range is the speed when most users use the mobile terminal. According to the variation range of the motion speed, the frequency variation range can be determined by the Doppler effect, and in the Doppler effect, the relation between the speed and the frequency is as follows:

where f is the frequency of the ultrasonic signal received by the ultrasonic receiving device, i.e. the frequency of the second ultrasonic signal, f₀Is the fundamental frequency of the first ultrasonic signal, c is the propagation velocity of the ultrasonic signal in air, 340m/s (meters per second), Δ v is the velocity of the obstacle relative to the ultrasonic sound source, i.e., the velocity at which the user uses the mobile terminal; thereby changing the frequency

When the basic frequency of the ultrasonic signal is 40KHz and the speed of the obstacle relative to the mobile terminal is changed between 0.085 m/s and 17m/s, the frequency change range is 10Hz to 20 KHz. According to the basic frequency of the ultrasonic signal and the speed of most users using the mobile terminal, the corresponding frequency change range is determined, and the requirements of most users can be met.

In this embodiment, it is considered that the speed of the user picking up the mobile terminal varies within a certain range, so that the frequency variation of the second ultrasonic signal received by the ultrasonic wave receiving device also correspondingly varies within a certain range, that is, a frequency variation range.

In step S36, a frequency change section is determined based on the fundamental frequency and the reception frequency change range.

In the present embodiment, the areas involved in calculating the doppler effect area difference are referred to as a first area and a second area, respectively.

The frequency variation range of the ultrasonic signal includes an upper limit value and a lower limit value, and the increase and decrease of the fundamental frequency depend on the difference of the relational expression between the fundamental frequency and the frequency variation range.

The process of calculating the frequency change interval corresponding to the first area according to the fundamental frequency and the frequency change range is as follows: and determining a frequency change interval according to a relational expression between the basic frequency and the upper limit value and the lower limit value. Specifically, if the interval is an interval in which the frequency of the second ultrasonic signal is greater than the fundamental frequency, the relational expression is to sum the fundamental frequency and the frequency variation range to increase the receiving frequency corresponding to the second ultrasonic signal. For example, when the fundamental frequency is 40KHz, the frequency variation range is 10Hz to 20KHz, the upper limit value is 20KHz, the lower limit value is 10Hz, the relational expressions corresponding to the first areas are (40+20) KHz and (40+0.01) KHz, and the corresponding frequency variation intervals are (40+0.01) to (40+20) KHz.

The process of calculating the frequency change interval corresponding to the second area according to the fundamental frequency and the frequency change range is as follows: and determining a frequency change interval according to a relational expression between the basic frequency and the upper limit value and the lower limit value. Specifically, the interval is an interval in which the frequency of the second ultrasonic signal is smaller than the fundamental frequency, and the relational expression corresponding to the second area is a relational expression in which the fundamental frequency and the upper limit value and the lower limit value of the frequency variation range are subtracted to reduce the reception frequency corresponding to the second ultrasonic signal. If the basic frequency is 40KHz, the frequency variation range is 10 Hz-20 KHz, the upper limit value is 20KHz, the lower limit value is 10Hz, the corresponding relational expressions of the second area are (40-20) KHz and (40-0.01) KHz, and the corresponding frequency variation interval is (40-20) KHz to (40-0.01) KHz.

In step S37, the doppler effect area difference of the ultrasonic signal is calculated from the frequency variation section and the intensity variation curve corresponding to the frequency variation section.

Referring to fig. 8, after the frequency change section corresponding to the calculation of the first area is determined, the intensity change curve corresponding to the frequency change section is determined. Wherein the intensity variation curve is recorded in the transmission process of the ultrasonic signal. After the intensity change curve is determined, the intensity value of the Y axis corresponding to the starting point and the ending point of the frequency change interval, the frequency change range on the X axis of the interval and the area of a closed area surrounded by the intensity change curve of the frequency change interval are used as first areas, and the size of the first area can be obtained by integrating the X axis through the intensity change curve according to the upper limit value and the lower limit value of the frequency change interval corresponding to the first area. It is understood that the process of calculating the second area is the same as the process of calculating the first area, and will not be described herein.

And after the first area and the second area are obtained, the mobile terminal subtracts the second area from the first area to obtain an area difference between the first area and the second area, and the area difference is recorded as a Doppler effect area difference of the ultrasonic wave.

And step S38, controlling the mobile terminal according to the Doppler effect area difference based on the application program running in the mobile terminal.

And when the Doppler effect area difference is obtained through calculation, determining whether the Doppler effect area difference is a positive value or a negative value. Specifically, the doppler effect area difference is compared with 0, and if the doppler effect area difference is smaller than 0, the doppler effect area difference is determined to be a negative value; and if the Doppler effect area difference is larger than 0, determining that the Doppler effect area difference is a positive value. When the Doppler effect area difference is determined to be a positive value, the mobile terminal determines that the mobile terminal approaches to the obstacle currently, namely the mobile terminal makes approaching movement relative to the obstacle; when the Doppler effect area difference is determined to be a negative value, the mobile terminal determines that the mobile terminal is far away from the obstacle currently, namely the mobile terminal does far movement relative to the obstacle. And after the movement trend of the mobile terminal relative to the barrier is determined through the Doppler area difference, the mobile terminal determines a corresponding operation instruction according to the running application program and the movement trend, and realizes control operation according to the operation instruction.

It should be noted that, in order to improve the accuracy of controlling the mobile terminal according to the ultrasonic signal, the amplitude change rate and the doppler effect area difference may be used together to control the mobile terminal, and only when both the amplitude change rate and the doppler effect area difference satisfy the condition, the movement trend of the mobile terminal relative to the obstacle is determined.

Further, the method for controlling the mobile terminal further includes:

and e, determining the frequency variation range of the second ultrasonic signal according to the preset movement speed of the mobile terminal relative to the obstacle.

Due to the relative motion between the mobile terminal and the obstacle, the frequency of the second ultrasonic signal is different from the basic frequency of the first ultrasonic signal, and the frequency change range is determined by the speed change range of the relative motion between the mobile terminal and the obstacle. It can be understood that the relative motion between the mobile terminal and the obstacle is essentially the relative motion between the mobile terminal and the trunk or head of the user when the user picks up the mobile terminal during the use of the mobile terminal. The speed of the user for picking up the mobile terminal is changed within a certain range, and the specific change range can determine the speed of most users for using the mobile terminal in a test mode. And taking the speed meeting the requirements of most users as a preset movement speed of the mobile terminal, and determining the frequency change range of the ultrasonic wave receiving device for receiving the ultrasonic wave signals according to the preset movement speed.

Further, the preset moving speed includes a minimum moving speed and a maximum moving speed, and step d includes:

and e1, determining the lower limit value of the frequency variation range of the second ultrasonic signal received by the ultrasonic receiving device according to the minimum movement speed and the transmitting frequency.

And e2, determining the upper limit value of the frequency variation range of the second ultrasonic signal received by the ultrasonic receiving device according to the maximum movement speed and the transmitting frequency.

Further, considering that the speeds of different users using the mobile terminal are different, in the embodiment of the present invention, the used speed range may represent the speed of most users using the mobile terminal, that is, the preset moving speed is a speed range including the minimum moving speed and the maximum moving speed. Specifically, according to the change relationship between the frequency and the velocity in the doppler effect, according to the minimum motion velocity and the fundamental frequency of the first ultrasonic signal, the lower limit value of the frequency change range of the second ultrasonic signal can be determined; accordingly, the upper limit value of the frequency variation range of the second ultrasonic signal can be determined according to the maximum movement speed.

In this embodiment, the doppler effect area difference is calculated by determining the basis corresponding to the first ultrasonic signal and the frequency change rate range of the second ultrasonic signal, and the mobile terminal is controlled according to the doppler effect area difference and the application program running in the mobile terminal. The mobile terminal can be intelligently controlled through the Doppler effect area difference corresponding to the ultrasonic signals.
