The shell 1 is made of metal material, which is more conducive to shielding the interference of the external magnetic field. The PCB board 2 is provided with two pairs of electromagnetic wave transmitting coils 4 and electromagnetic wave receiving coils 5, and the connecting lines of the two pairs of electromagnetic wave transmitting coils 4 and electromagnetic wave receiving coils 5 are perpendicular. The rocker mechanism 3 includes a rocker 301, an X-axis rocker arm 302 and a Y-axis rocker arm 303. The X-axis rocker arm 302 is provided with a Z-axis clearance channel 304 in the middle, and X-axis support shafts 305 are provided on both sides. Y-axis shaft holes 306 are provided on both sides of the Z-axis clearance channel 304.

The two ends of the rocker arm 303 are provided with a Y-axis support shaft 309 coaxial with the Y-axis end 307 on the rocker 301, and the X-axis support shaft 305 and the Y-axis support shaft 309 are installed in the support shaft hole 310 on the housing 1. The adjacent pair of X-axis support shafts 305 and Y-axis support shafts 309 on the rocker mechanism 3 are provided with an electromagnetic wave shielding part 311, and the electromagnetic wave shielding part 311 is made of metal, graphene or ceramic material, wherein: metal is one of the most common materials currently used to block electromagnetic waves. Metal can absorb electromagnetic waves and convert them into heat energy. Commonly used metal materials include aluminum, iron, copper, tin, etc. Since metal has good conductivity and reflectivity, it is very effective in electromagnetic wave shielding. Graphene is a new type of carbon material, which is one of the thinnest, strongest and most conductive materials at present. Graphene can be used to make electromagnetic wave shielding films, radiation-proof clothing and other products. Graphene shielding material has excellent electromagnetic wave shielding effect and high mechanical strength, and can effectively block high-frequency electromagnetic waves and microwave radiation. Ceramic material is a non-metallic material with excellent electromagnetic wave shielding performance. Ceramic material is divided into two types: low dielectric constant ceramic and high dielectric constant ceramic. Low dielectric constant ceramic can effectively block high-frequency electromagnetic waves, and high dielectric constant ceramic can block lower frequency electromagnetic waves. The lower edges of the two electromagnetic wave shielding parts 311 are respectively located between the two pairs of electromagnetic wave transmitting coils 4 and electromagnetic wave receiving coils 5, and the lower edges of the electromagnetic wave shielding parts 311 are provided with oblique cuts 312; the bottom end of the rocker 301 is provided with an elastic retractable part 316 that can be elastically retracted at the bottom of the rocker 301, so that the rocker 301 can automatically reset after swinging. When the rocker 301 swings, the rocker 301 drives the electromagnetic wave shielding part 311 to rotate, so that the number of magnetic lines of force shielded by the electromagnetic wave shielding part 311 between the electromagnetic wave transmitting coil 4 and the electromagnetic wave receiving coil 5 changes. When the number of magnetic lines of force shielded by the electromagnetic wave shielding part 311 increases, the magnetic flux decreases and the voltage decreases, otherwise the magnetic flux increases and the voltage increases.The voltage signal is transmitted from the electromagnetic wave receiving coil 5 to the mainboard single chip microcomputer, and the mainboard single chip microcomputer comprehensively determines the rotation direction and position of the joystick 301 according to the size changes of the two voltage values generated by the two pairs of electromagnetic wave transmitting coils 4 and the electromagnetic wave receiving coils 5. The electromagnetic wave potential device of this embodiment can be applied to game controllers, joysticks of entertainment equipment, etc.
[0025] Example 2: Figure 6 , Figure 7 As shown, an electromagnetic wave potential device includes a shell 1, a PCB board 2 and a rocker mechanism 3. The shell 1 is made of metal material, which is more conducive to shielding the interference of the external magnetic field. Two pairs of electromagnetic wave transmitting coils 4 and electromagnetic wave receiving coils 5 are arranged on the PCB board 2. The connecting lines of the two pairs of electromagnetic wave transmitting coils 4 and the electromagnetic wave receiving coils 5 are perpendicular to each other. The rocker mechanism 3 includes a rocker 301, a spherical piece 313 and a spring 314. The top of the shell 1 is set as a rocker support seat 101. The spherical piece 313 is fixed to the middle of the rocker 301. The rocker support seat 101 is provided with a spherical groove 102. The spherical piece 313 is placed in the spherical groove 102. The surface groove 102 forms a spherical match with the spherical groove 102, so that the rocker 301 can swing in all directions. The lower end of the rocker 301 is provided with an electromagnetic wave shielding part 311, and the electromagnetic wave shielding part 311 is made of metal material. In this embodiment, the electromagnetic wave shielding part 311 is in the shape of a hemispherical mask. The lower edge of the electromagnetic wave shielding part 311 is located between the electromagnetic wave transmitting coil 4 and the electromagnetic wave receiving coil 5, and the lowest point is roughly located in the middle of the electromagnetic wave transmitting coil 4 and the electromagnetic wave receiving coil 5. The spring 314 is installed between the electromagnetic wave shielding part 311 and the bottom surface of the rocker support seat 101 to ensure that the rocker 301 can automatically reset after swinging. When the rocker 301 swings, the rocker 301 drives the electromagnetic wave shielding part 311 to swing, so that the number of magnetic lines of force shielded by the electromagnetic wave shielding part 311 changes. When the number of magnetic lines of force shielded by the electromagnetic wave shielding part 311 increases, the magnetic flux decreases and the voltage decreases. Conversely, the magnetic flux increases and the voltage increases. The voltage signal is transmitted from the electromagnetic wave receiving coil 5 to the mainboard single chip microcomputer, and the mainboard single chip microcomputer comprehensively determines the rotation direction and position of the joystick 301 according to the size changes of the two voltage values generated by the two pairs of electromagnetic wave transmitting coils 4 and the electromagnetic wave receiving coils 5.

The housing 1 includes a bottom shell 103 and a cover 104. The bottom shell 103 is set as a rocker mounting seat. One end of the rocker 301 can be swingably or universally rotatably mounted on the rocker mounting seat, and a reset member 315 capable of resetting the rocker 301 is provided. The reset member 315 is a torsion spring or a spring, etc. In this embodiment, a torsion spring is used. The rod body of the rocker 301 is set as an electromagnetic wave shielding part. The rod body of the rocker 301 is made of metal material or has a metal surface, and is located between the electromagnetic wave transmitting coil 4 and the electromagnetic wave receiving coil 5. When the rocker 301 as the electromagnetic wave shielding part swings, the rocker 301 shields or releases the magnetic field lines between the electromagnetic wave transmitting coil 4 and the electromagnetic wave receiving coil 5, so that the magnetic flux and the corresponding voltage value change. The voltage signal is transmitted from the electromagnetic wave receiving coil 5 to the mainboard microcontroller, and the mainboard microcontroller determines the action of the rocker 301 according to the change in the voltage value. The electromagnetic wave potential device of this embodiment can be combined with other driving mechanisms (such as a push-down mechanism, a connecting rod mechanism, and a rotating shaft lever mechanism) to be applied to buttons, trigger keys, knobs, etc. of a game controller.
