[0047] The present invention proposes a joystick device to improve the user experience. The joystick device can be used in control devices in the fields of games or drones. The following is an example of its application in games. For ease of understanding and explanation, the following is an appendix to the specification of the present invention. Figures 1 to 5 In the figure, the solid arrow indicates the slot.

[0048] See also Figures 1 to 5 In one embodiment of the present invention, the rocker 100 device 10 includes a rocker 100, a rocker arm assembly 200, a first circuit board 300, a first TMR sensor assembly 400, a second circuit board 500 and a second TMR sensor assembly 600, wherein the rocker arm assembly 200 includes an upper rocker arm 210 and a lower rocker arm 220 arranged orthogonally to each other, and the rocker 100 passes through the upper rocker arm 210 and the lower rocker arm 220; the first TMR sensor assembly 400 includes a first TMR sensor element 410 and a first magnet, wherein the first magnet is arranged on the peripheral side of the upper rocker arm 210, and the first magnet is arranged on the peripheral side of the upper rocker arm 210. The body is integrally arranged with the upper rocker arm 210; the first TMR sensor element 410 is arranged on the first circuit board 300 corresponding to the position of the first magnet, and is electrically connected to the first circuit board 300; the second TMR sensor component 600 includes a second TMR sensor element 610 and a second magnet, the second magnet is arranged on the peripheral side of the lower rocker arm 220, and the second magnet is integrally arranged with the lower rocker arm 220; the second TMR sensor element 610 is arranged on the second circuit board 500 corresponding to the position of the second magnet, and is electrically connected to the second circuit board 500.

[0049] The TMR (tunnel magnetoresistance) sensor is a highly sensitive magnetic field sensor that uses the tunnel magnetoresistance effect to detect changes in the external magnetic field. As the magnet moves in the direction of motion, the TMR sensor senses the angle of rotation of the magnetic field to determine the rotational position. The TMR sensor operates in a saturated magnetic field.

[0050] Working principle: When the user moves the joystick 100, the joystick 100 pushes the upper rocker arm 210 or the lower rocker arm 220 to swing. At this time, the position and direction of the first magnet located in the upper rocker arm 210 and the second magnet located in the lower rocker arm 220 change, and the direction and intensity of the magnetic field detected by the first TMR sensor element 410 and the second TMR sensor element 610 change accordingly. The tunnel magnetoresistance elements inside the first TMR sensor element 410 and the second TMR sensor element 610 are very sensitive to changes in the magnetic field. They will change their resistance value according to changes in the direction and intensity of the magnetic field. The resistance change of the tunnel magnetoresistance element of the MR sensor element 610 is converted into a voltage or current signal by the internal bridge circuit and output through the first circuit board 300 and the second circuit board 500; the controller (such as a microcontroller or a dedicated signal processing chip) samples and reads the output signals of the first TMR sensor element 410 and the second TMR sensor element 610, and converts the electrical signals into specific direction and angle data. The processed direction data is transmitted to the game system as an input signal for controlling the game character. The game system adjusts the movement direction and speed of the game character according to these input signals to achieve control of the character.

[0051] In this embodiment, the first TMR sensor element 410 and the second TMR sensor element 610 are directly integrated on the circuit board and correspond to the magnets of the upper rocker arm 210 and the lower rocker arm 220. The first TMR sensor element 410 corresponds to the first magnet being integrally arranged with the upper rocker arm 210, and the second TMR sensor element 610 corresponds to the second magnet being integrally arranged with the lower rocker arm 220. The integrated arrangement of the magnet and the rocker arm prevents the magnet from changing due to loosening or displacement during installation or use, which enables the TMR sensor element to better sense the position change of the magnet, thereby improving the detection accuracy, simplifying the assembly process, and reducing the accuracy problem caused by assembly error. In addition, the integrated design of the magnet and the rocker arm enables the movement of the rocker arm to be better reflected on the magnet, reducing the lag in the signal transmission path and improving the response speed of the system. In addition, due to the characteristics of the output signal of the TMR sensor element, the signal processing system on the circuit board can process these signals more efficiently, thereby further reducing the response delay of the overall system and providing a better user experience.

[0052] In an embodiment of the present application, the first magnet is integrally provided with the upper rocker arm 210; the second magnet is integrally provided with the lower rocker arm 220; including but not limited to an integral molding setting, a 3D printing molding setting or an adhesive bonding setting; preferably, the first magnet is integrally formed with the upper rocker arm 210; the second magnet is integrally formed with the lower rocker arm 220, wherein the integral molding here refers to an integral injection molding setting.

[0053] Regarding the shapes of the first magnet and the second magnet, they can be cylindrical, annular and rectangular, and of course, they can also be other regular or irregular shapes. For example, the first magnet is arranged in a cylindrical shape, and the second magnet is arranged in a cylindrical shape.

[0054] Regarding the polarity distribution of the first magnet and the second magnet, there are axial polarization, radial polarization and bipolar polarization. Taking the cylindrical shape as an example, axial polarization means that the polarity of the magnet is distributed along the axial direction of the magnet, with one end face being the north pole and the other end face being the south pole. Radial polarization means that the polarity of the magnet is distributed along the radial direction (i.e. from the center outward), and the periphery and center of the magnet have different polarities. Bipolar polarization means (such as Figure 6 As shown in Figure 1): The magnet is divided into two halves along the diameter direction, one half is the North Pole (N pole) and the other half is the South Pole (S pole). The magnetic field lines pass from the North pole half to the South pole half, forming a continuous magnetic field from one side of the magnet to the other.

[0055] In an exemplary embodiment, the first magnet has two opposite sides along its radial direction, and the polarities of the two sides of the first magnet are different, that is, the diameter direction of the magnet is the dividing line of the magnetic poles, half of which is the north pole (N pole) and the other half is the south pole (S pole); for example, Figure 6 As shown, the left side may be the North Pole and the right side may be the South Pole.

[0056] In an exemplary embodiment, the second magnet has two opposite sides along its radial direction, and the polarities of the two sides of the second magnet are different. That is, the diameter direction of the magnet is the dividing line of the magnetic poles, half of which is the north pole (N pole) and the other half is the south pole (S pole); for example, Figure 6 As shown, the left side may be the North Pole and the right side may be the South Pole.

[0057] In the above two embodiments, the diameter direction of the magnet is the dividing line of the magnetic poles, with the north pole on one side and the south pole on the other side. This distribution method allows the TMR sensor element to better detect obvious magnetic field changes when the magnet rotates or moves, thereby improving detection accuracy.

[0058] In order to verify the superiority of the technical solution of this utility model, Figure 1 The embodiment shown in FIG. 1 is tested and it is found that when the upper rocker arm 210 and the lower rocker arm 220 swing back and forth 30 degrees, the output curve is as follows: Figure 7 As shown, the output voltage changes linearly, and the position can be directly calculated linearly.

[0059] As can be seen, in the technical solution of this embodiment, since the output voltage of the joystick 100 device 10 presents a linear change, and there is a direct proportional relationship between the linearly changing output voltage and the measured value, the processing and interpretation of the sensor output signal becomes very simple and intuitive. The linear transformation can be processed by simple mathematical operations (such as proportional scaling) without the need for complex nonlinear correction algorithms. This also makes the remote control system error and random error usually evenly distributed throughout the entire range, thereby reducing the accumulation of total error, improving overall accuracy, and making it easier to integrate into a larger system, avoiding the introduction of additional complexity and potential error sources in the system design. Furthermore, the linear output simplifies the data processing and analysis process, and linear signals are easier to convert and process. For example, when converting analog signals to digital signals, the linear relationship allows for the use of simple linear interpolation or scaling algorithms. The linear change of the output voltage allows the use of high-precision amplification and measurement circuits, which allows even tiny changes to be accurately detected, thereby improving the control accuracy of the joystick 100 device 10.
