[0023] The present invention is further described in detail below with reference to the accompanying drawings.

[0024] Example 1: Figures 1 to 5 As shown, an electromagnetic wave potential module includes a PCB board 1, a rocker mechanism 2 and a shell 3. The shell 3 is made of metal material, which is more conducive to shielding the interference of the external magnetic field. An electromagnetic wave receiving coil 4 is respectively provided in two perpendicular directions on the PCB board 1, for a total of two electromagnetic wave receiving coils 4; the rocker mechanism 2 includes a rocker 201, an X-direction rocker arm 202 and a Y-direction rocker arm 203. The X-direction rocker arm 202 has a Z-direction clearance channel 204 in the middle, and X-direction support shafts 205 on both sides. Y-direction shaft holes 206 are provided on both sides of the Z-direction clearance channel 204. The rocker 201 is provided with a Y-direction shaft end 207, which is installed in the Y-direction shaft hole 206, so that the rocker 201 can swing in the X direction; the Y-direction The rocker arm 203 has a Z-shaped opening 208 for the rocker 201 to pass through. Y-shaped support shafts 209 are located at both ends of the rocker arm 203, coaxial with the Y-shaped shaft end 207 of the rocker 201. The X-shaped support shafts 205 and 209 are mounted in support shaft holes 210 in the housing 3. Each of the X-shaped support shafts 205 and 209 has a swing arm 211 at one end. Two electromagnetic wave transmitting coils 5 are mounted on each swing arm 211, corresponding to the positions of the two electromagnetic wave receiving coils 4 on the PCB 1. Both electromagnetic wave transmitting coils 5 are connected to the PCB 1 via flexible conductors (not shown). The bottom end of the rocker arm 201 is equipped with an elastic member 216 that can be retracted and retracted to ensure that the rocker 201 automatically returns to its original position after rocking. When the joystick 201 swings, it moves the electromagnetic wave transmitting coil 5 away from or toward the electromagnetic wave receiving coil 4, causing the magnetic flux received by the electromagnetic wave receiving coil 4 to change. When the electromagnetic wave transmitting coil 5 moves away from the electromagnetic wave receiving coil 4, the magnetic flux decreases, and the voltage decreases. When the electromagnetic wave transmitting coil 5 moves closer to the electromagnetic wave receiving coil 4, the magnetic flux increases, and the voltage increases. This voltage signal is transmitted by the electromagnetic wave receiving coil 4 to the mainboard microcontroller. The mainboard microcontroller determines the rotation direction and position of the joystick 201 based on the changes in the two voltage values ​​generated by the two pairs of electromagnetic wave transmitting coils 5 and electromagnetic wave receiving coils 4. The electromagnetic wave potential module of this embodiment can be applied to the joystick 201 of game controllers, entertainment devices, and the like.

[0025] Example 2: Figure 6 、 Figure 7As shown, an electromagnetic wave potential module includes a PCB board 1, a rocker mechanism 2 and a housing 3. The housing 3 is made of metal material and is more conducive to shielding interference from external magnetic fields. An electromagnetic wave receiving coil 4 is respectively provided in two perpendicular directions on the PCB board 1, for a total of two electromagnetic wave receiving coils 4; the rocker mechanism 2 includes a rocker 201, a spherical member 212 and a spring 213. The top of the housing 3 is provided with a rocker support seat 301. The spherical member 212 is fixed to the middle of the rocker 201. The rocker support seat 301 is provided with a spherical groove 302. The spherical member 212 is placed in the spherical groove 302 and forms a spherical fit with the spherical groove 302, allowing the rocker 201 to swing in all directions. The rocker 201 is provided with a coil fixing seat 214 and is equipped with two electromagnetic wave transmitting coils 5. The two electromagnetic wave transmitting coils 5 are connected to the PCB board 1 via flexible wires (not shown in the figure). The two electromagnetic wave transmitting coils 5 correspond one-to-one with the two electromagnetic wave receiving coils 4 on the PCB board 1. The spring 213 is mounted between the coil holder 214 and the bottom surface of the rocker support 301. This spring 213 ensures that the rocker 201 automatically resets after swinging. When the rocker 201 swings, it drives the electromagnetic wave transmitting coil 5 away from or toward the electromagnetic wave receiving coil 4, causing the magnetic flux received by the electromagnetic wave receiving coil 4 to change. When the electromagnetic wave transmitting coil 5 moves away from the electromagnetic wave receiving coil 4, the magnetic flux decreases, and the voltage decreases. When the electromagnetic wave transmitting coil 5 moves closer to the electromagnetic wave receiving coil 4, the magnetic flux increases, and the voltage increases. This voltage signal is transmitted by the electromagnetic wave receiving coil 4 to the mainboard microcontroller. The mainboard microcontroller determines the rotation direction and position of the rocker 201 based on the changes in the two voltage values ​​generated by the two pairs of electromagnetic wave transmitting coils 5 and the electromagnetic wave receiving coil 4. The electromagnetic wave potential module of this embodiment can be applied to the rocker 201 of game controllers, entertainment devices, and the like.

[0026] Example 3: Figure 8 、 Figure 9As shown, an electromagnetic wave potential module includes a PCB board 1, a rocker mechanism 2 and a shell 3. The shell 3 is made of metal material, which is more conducive to shielding the interference of the external magnetic field. The PCB board 1 has four or eight electromagnetic wave receiving coils 4 (four in this embodiment) evenly distributed in the circumferential direction; the rocker mechanism 2 includes a rocker 201, a spherical member 212 and a spring 213. The top of the shell 3 is set as a rocker support seat 301, the spherical member 212 is fixed to the middle of the rocker 201, and the rocker support seat 301 is fixed to the middle of the rocker 201. 01 is provided with a spherical groove 302. The spherical member 212 is positioned within this groove and forms a spherical fit with it, enabling universal swing of the rocker 201. The rocker 201 is provided with a coil holder 214, on which an electromagnetic wave transmitting coil 5 is mounted. The electromagnetic wave transmitting coil 5 is connected to the PCB 1 via a flexible conductor (not shown). The spring 213 is mounted between the coil holder 214 and the bottom surface of the rocker support 301. This spring ensures that the rocker automatically returns to its original position after swinging. When the rocker 201 swings, it moves the electromagnetic wave transmitting coil 5 away from or toward the electromagnetic wave receiving coil 4, causing the magnetic flux received by the electromagnetic wave receiving coil 4 to change. When the electromagnetic wave transmitting coil 5 moves away from a particular electromagnetic wave receiving coil 4, the magnetic flux and voltage of that electromagnetic wave receiving coil 4 decrease. When the electromagnetic wave transmitting coil 5 moves closer to a particular electromagnetic wave receiving coil 4, the magnetic flux and voltage of that electromagnetic wave receiving coil 4 increase. This voltage signal is transmitted by the electromagnetic wave receiving coil 4 to the mainboard microcontroller, which determines the rotation direction and position of the joystick 201 based on the changes in the magnitude of the four voltage values ​​generated by the four electromagnetic wave receiving coils 4. The electromagnetic wave potential module of this embodiment can be applied to game controllers, joysticks 201 of entertainment devices, etc.

[0027] Example 4: Figure 10 、 Figure 11The present invention shows an electromagnetic wave potential module comprising a PCB 1, a rocker mechanism 2, and a housing 3. The housing 3 is made of metal to better shield against interference from external magnetic fields. An electromagnetic wave receiving coil 4 is mounted on the PCB 1. The rocker mechanism 2 includes a rocker 201 and a mounting base for the rocker 201. One end of the rocker 201 is mounted on the mounting base for swinging or universal rotation. A reset member, a torsion spring 215, is provided to reset the rocker 201. An electromagnetic wave transmitting coil 5 is fixed to one side of the rocker 201. The electromagnetic wave transmitting coil 5 is connected to the PCB 1 via a flexible conductor (not shown). The position of the electromagnetic wave transmitting coil 5 corresponds to the position of the electromagnetic wave receiving coil 4 on the PCB 1. When the rocker 201 swings, the electromagnetic wave transmitting coil 5 on the rocker 201 moves closer to or further away from the electromagnetic wave receiving coil 4, causing the magnetic flux and corresponding voltage value of the electromagnetic wave receiving coil 4 to change. This voltage signal is transmitted by the electromagnetic wave receiving coil 4 to the mainboard microcontroller, which determines the movement of the joystick 201 based on the change in voltage. The electromagnetic wave potential module of this embodiment can be combined with other drive mechanisms (such as a push-down mechanism, a connecting rod mechanism, and a rotating shaft lever mechanism) and applied to buttons, triggers, knobs, etc. of a game controller.
