The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.

In order to make the embodiment of the present invention more clear, the operation principle of the induction coil related to the embodiment is explained below. When Alternating Current (AC) flows through the inductor, an AC magnetic field is generated, and if a conductive material (e.g., a piece of metal) is placed near the inductor, circulating currents (eddy currents) are induced on the surface of the conductor by the AC magnetic field. Fig. 2 is a schematic diagram of the operating principle of the induction coil according to the embodiment of the present invention, as shown in fig. 2, the magnitude of the generated circulating current has a functional relationship with the size of the conductor and the distance between the conductor and the induction coil, the magnetic field generated by the eddy current itself will resist the magnetic field generated by the induction coil, and the effect is equivalent to a set of coupling inductances; wherein the induction coil inductance is a primary inductance and the eddy currents in the conductor represent a secondary inductance; the coupling relationship between the two inductances can be expressed as: induction coil inductance and proximate conductor resistivity, distance, size and shape; wherein the resistance and inductance of the secondary inductance caused by eddy currents can be equivalently modeled as resistance and inductance components related to the distance on the primary side (induction coil); according to the working principle of the induction coil, the inventor finds that: the above-mentioned coupled inductive effect can be created if the induction coil is arranged inside the metal rim and/or the metal back cover of the terminal. When external force presses (or touches) the frame/rear cover at the position of the induction coil, the frame/rear cover deforms, the deformation causes the distance in the equivalent model to be reduced, both the primary inductance and the secondary inductance change due to the coupling inductance effect, and when the change of the primary inductance is fed back through the induction coil, the external force pressing (or touch screen) operation can be recognized.

It should be noted that, in the embodiment of the present invention, when the induction coil is disposed inside the frame of the terminal, the frame may be a metal frame; when the induction coil is arranged on the inner side of the rear cover of the terminal, the rear cover can be a metal rear cover. In addition to the metal frame and/or the metal rear cover, the frame and/or the rear cover of the terminal according to the embodiment of the present invention may be a frame and/or a rear cover made of other materials and provided with a metal medium cooperating with the induction coil; for example, a metal medium is correspondingly arranged in the frame and/or the rear cover area opposite to the induction coil, and an induction change value is obtained by the induction coil in the process of pressing the metal medium; in addition, the embodiment of the invention can perform the distribution setting of the induction coils based on the operation habit of the user; for terminals with different sizes, the arrangement and distribution of the induction coils are different, for example, when a mobile phone with a 5-inch screen and a tablet with a 6-inch screen are applied, the positions of the induction coils are different; according to the embodiment of the invention, the induction coil can be set by referring to the size of the terminal and combining with the habits of most users on application operation of the terminal obtained by statistics. Fig. 4 is a schematic diagram of the distribution of the positions of the induction coils according to the embodiment of the present invention, and as shown in fig. 4, the areas where the user may perform application operations on the terminal by holding the terminal with the left hand and holding the terminal with the right hand are used as the areas for arranging the induction coils; in the embodiment of the present invention, when the trigger instruction and the operation instruction are generated, if a plurality of induction coils are arranged on the inner side of the frame, the induction coils may be uniformly distributed in the preset area, for example, one induction coil is arranged at every preset interval on a straight line along the frame. Fig. 5 is a schematic diagram of the position distribution of the induction coils according to another embodiment of the present invention, as shown in fig. 5, the induction coils are disposed on the inner side (the area where the dashed line frame is located) of the rear metal cover of the terminal; when the embodiment of the invention generates the trigger instruction and the operation instruction, two or more than two induction coils can be arranged on the inner side of the metal frame and the inner side of the metal rear cover of the terminal at the same time.

Taking the example that the terminal is provided with 3 induction coils, and each induction coil comprises three induction effective intervals; the three induction effective intervals of the induction coil 1 can be expressed as: the induction effective interval 1, the induction effective interval 2 and the induction effective interval 3; the three induction effective intervals of the induction coil 2 can be expressed as: an induction effective interval 4, an induction effective interval 5 and an induction effective interval 6; the three induction effective intervals of the induction coil 3 can be expressed as: an induction effective interval 7, an induction effective interval 8 and an induction effective interval 9; the set induction effective interval may be stored by a database, and table 1 is the content of the above example, where part of the induction effective intervals in the table may be the same, for example, induction effective interval 1 and induction effective interval 7 may be the same.
