In this embodiment, the magnetic induction element 6 is a magnetic induction chip. The control element 5 is a single chip microcomputer which is provided with a power supply and a data transmission interface. The single chip microcomputer is connected to a game controller mainboard through electric wires and comprises 6 conducting wires, wherein the power supply positive electrode and the power supply negative electrode are respectively provided, and the vertical and horizontal signal wires are respectively provided.

Connecting block 8 and connecting hole 7 match each other, and the surface of connecting block 8 is the sphere arc, and rod core 2 wears to establish in connecting block 8. When a user pulls the upper part of the rod core 2, the permanent magnet 3 at the bottom end can move in the opposite direction through the connecting block 8, so that the magnetic field intensity induced by the magnetic induction chip is changed, and the analog electric signal output by the magnetic induction chip is correspondingly changed.

Specifically, the return mechanism comprises a spring washer 9, a pressure spring 10 and a spring base 4 which are sequentially arranged from top to bottom, and the spring washer 9, the pressure spring 10 and the spring base 4 are movably sleeved on the rod core 2.

When a user pulls the upper end of the rod core 2 in the horizontal direction, the connecting hole 7 of the mounting part 1 through which the rod core 2 passes is larger than the diameter of the rod core 2, so that the rod core 2 can move freely in a limited range, and when the rod core 2 is not stressed, the sleeved pressure spring 10 at the bottom of the rod core 2 can enable the rod core 2 to return to the upright state.

EXAMPLE III

The embodiment provides a control method of a joystick, which is used for controlling the joystick in the first embodiment and the second embodiment, and the control method is written into a single chip microcomputer through setting software of a computer end.

In this embodiment, the logic control method of the single chip microcomputer specifically includes:

firstly, a two-dimensional coordinate system is defined by the singlechip program, wherein the horizontal axis represents an x axis, and the vertical axis represents a y axis.

And 1, x-axis and y-axis range values, wherein the range of the coordinate values of the permanent magnet is set by a singlechip program for convenient calculation, and when the coordinate values exceed the range, the values are assigned according to the upper limit and the lower limit of the range. The significance of setting the range value lies in controlling the value of the coordinate system in a limited range, facilitating subsequent various logic judgments and simultaneously avoiding error data accidentally generated by the magnetic induction chip due to electrical problems.

And 2, correcting the x-axis and y-axis data, wherein the generated x-axis and y-axis data can deviate under the conditions of different magnetic field strengths, magnet sizes, distance, power supply voltage current fluctuation and the like of the magnetic induction chip. In order to make the single chip correctly recognize the operation of the user, the data transmitted by the magnetic induction chip needs to be corrected. The method used for correction is generally a variable or a function containing variable parameters. Let x0 be the original data, x be the modified data, and f () be the modification function, then x equals f (x 0). The significance of setting the correction function is that the user can recalibrate the rocker by himself, so that the use accuracy of the rocker is improved.

3. Minimum trigger unit definition: the minimum trigger unit is that in a two-dimensional coordinate system, an x-axis and a y-axis are divided according to precision requirements, and the original coordinate value range of the magnetic induction chip is further logically arranged, so that the whole coordinate system forms a grid system, a user can independently perform trigger feedback setting on each grid, and can also perform trigger feedback setting on the grids according to areas or ranges. The meaning of minimum trigger unit lies in, can control the precision of rocker according to user's needs, sets up higher unit density and can improve the response precision of rocker, otherwise then can reduce the precision, can also realize in addition that the simple motion through the rocker produces complicated output instruction, for example sets up different direction feedback values respectively for several adjacent units in a straight line direction, then the user will trigger the direction that sets up in proper order when promoting the rocker along this direction.

4. Non-trigger area definition: back to the central area. The middle-returning area means that the singlechip does not output a direction trigger signal to the game controller mainboard under the condition that the rod core is kept straight or deflected in a small range. The rocker sends a direction trigger signal to the game controller when the rod core moves beyond the range of the middle return area. In the single chip microcomputer program, the back-to-middle area is generally a group of x-axis and y-axis parameters, and under the simple condition, the back-to-middle area can be a rectangle in a single chip microcomputer coordinate system, and meanwhile, the back-to-middle area can be defined as a circle, an ellipse, a symmetrical polygon or an irregular geometric shape by using a geometric function. The significance of setting the range and the shape of the back center area is that a user can set the triggering distances in different directions individually, for example, if the up-down direction is more sensitive than the left-right direction, the y-axis parameter range of the back center area is smaller than the x-axis parameter range.

5. Diagonal zone definition: because the main board of the general game controller only receives signals of 4 directions, the other 4 directions are simulated by simultaneously triggering the two directions obliquely. Thus, with the inclusion of the echo zone, the coordinate system would be divided into 9 trigger regions: the rocking bar single chip can correct and judge the x-axis and y-axis data acquired from the magnetic induction chip so as to generate 9 different signals or signal combinations and transmit the signals to the game controller mainboard. The definition of the inclined direction area has the significance that a user can further set the triggering range of the rocker, and the problem of misoperation caused by personal habits can be effectively avoided by setting a certain inclined direction triggering area to be larger or smaller. Implementation of diagonal region definition: setting judgment parameters in an oblique direction: in a simple case, the oblique direction has a symmetrical shape, and each region has 2 straight line boundaries, (x0, y 0; x1, y1), (x0, y 0; x2, y2), wherein x0 and y0 represent the center point of the coordinate system, and x1, y1 and x2 and y2 represent the intersection points of two straight lines on the outer frame of the coordinate system respectively. The four oblique directions are respectively: upper right (x0, y 0; x1, y1), (x0, y 0; x2, y 2); upper left (x0, y 0; -x1, y1), (x0, y 0; -x2, y 2); bottom right (x0, y 0; x1, -y1), (x0, y 0; x2, -y 2); lower left (x0, y 0; -x1, -y1), (x0, y 0; -x2, -y2) outputs a corresponding diagonal direction signal to the game controller when the coordinate values are in the region between the two straight lines of each set. In the symmetric case, by setting the values of x1, y1 and x2, y2, the coordinate ranges of all four diagonal directions can be determined. Meanwhile, (x0, y 0; x1, y1), (x0, y 0; x2, y2) are respectively arranged; (x0, y 0; -x1, y1), (x0, y 0; -x2, y 2); (x0, y 0; x1, -y1), (x0, y 0; x2, -y 2); the values of (x0, y 0; -x1, -y1), (x0, y 0; -x2, -y2) give different ranges of diagonal orientations. In a complicated situation, the user can set all 8 straight lines respectively, that is, set 16 coordinate values respectively, so that 4 completely different oblique direction area ranges can be obtained.

6. Positive direction area definition: since only the positive direction exists after the back area and the oblique area are excluded, it is sufficient to compare which of the x value and the y value of the current coordinate is larger when the positive direction area is judged.

7. And (3) controlling a direction signal auxiliary script (auxiliary script for short) function: the auxiliary script function is mainly divided into the following two parts:

a. the automatic completion instruction function: an automatic completion instruction function switch is arranged in a single chip microcomputer program, and after the automatic carry-out instruction function is started, the direction signals can be automatically completed according to the direction operation sequence of a user. The significance of the automatic out-of-command function is as follows: when a user pulls the rod core at a high speed, the action may be deformed due to too high speed, so that some direction which is wanted to be triggered cannot be triggered correctly. The automatic completion function judges whether the middle direction is included between two adjacent directions actually triggered by the user, if yes, the middle direction is automatically added into an output sequence when a direction signal is sent to the game controller, so that the purpose of correcting the input of the user is achieved, and the instruction input error caused by the manipulation problem of the user is avoided. The realization of the automatic completion instruction function: the single chip microcomputer program records the direction value input last time by the user, compares the current input value, and if the direction input last time by the user is down and the input direction is left, the program adds the instruction output in the direction of the left-down direction to the position before the left-direction output, and the actually output direction sequence is down, left-down and left.

b. Macro command functions: the single chip microcomputer program is provided with a macro command function switch, and after the macro command function is started, a predefined series of direction sequences can be input to the game controller according to the direction operation of a user. The meaning of the macrocommand function is: the user can realize complex output through simple operation, thereby greatly simplifying the input difficulty of the user and improving the sales rate of the input instruction of the user. And (3) realizing a macro command function: in the singlechip program, a series of output direction instructions are stored as variables; the sequential triggering process of any coordinate area or a plurality of coordinate areas is used as a judgment basis, when the operation of a user meets the judgment condition, the singlechip program reads the variable containing the predefined direction sequence and sequentially outputs the direction sequence stored by the variable to the game controller, and in the output process, the rocker does not receive the operation instruction of the user any more until the sequence output is finished.

In summary, according to the joystick and the control method provided by the invention, the combination of the joystick and the control method can adapt to the manipulation habits of different users and the operation characteristics of different games, and meanwhile, the precision and the service life of the joystick can be improved. The magnetic induction technology is used for positioning, meanwhile, the triggering area and the response time can be adjusted through software, the accuracy of the user input instruction is improved, and the operation habits and the personalized requirements of the user can be better met during operation and control.
