[0025] The present invention provides a puck.

[0026] As in Fig. 1 to Fig. As shown in Figure 4, in an embodiment of the present invention the puck comprises a housing 100, a light-emitting device 200, a power source 300 and a magnetic induction switch 400.

[0027] a housing 100, wherein at least a part of the housing 100 is translucent; a light-emitting device 200, wherein the light-emitting device 200 is provided inside the housing 100 and is capable of emitting light to the outside through a translucent part of the housing 100; a power source 300, wherein the light-emitting device 200 is electrically connected to the power source 300; a magnetic induction switch 400, wherein the magnetic induction switch 400 is provided inside the housing 100 and is electrically connected to the power source 300 to control a conduction or an interruption of a circuit between the light-emitting device 200 and the power source 300 according to changes in an external magnetic field.

[0028] In this embodiment, the puck's housing 100 is made of a translucent material, preferably a translucent polyurethane material. This translucent polyurethane material offers cold resistance and can function normally even at -30°C. The puck's surface is frosted, resulting in more uniform and aesthetically pleasing light emission. Furthermore, the pattern printed on the surface using UV light is more attractive and wear-resistant. The combination of the translucent housing 100 and the light-emitting device 200 allows the puck to be observed in dark environments, thus enhancing the user experience at night or in dimly lit areas. Additionally, a power source 300 is integrated within the puck to supply power to the light-emitting device 200, thereby eliminating power consumption when the puck is not in use.A magnetic induction switch 400 is provided inside the housing 100, which is electrically connected to the power source 300, so that the puck can automatically control the light-emitting state when the external magnetic field changes due to the external magnetic object 600 near the puck, in order to increase interactivity and stimulation.

[0029] In one embodiment, the light-emitting device 200 comprises a control unit 210, a light-emitting element 220, a vibration sensor 230, and a printed circuit board 240, wherein the light-emitting element 220 and the vibration sensor 230 are electrically connected to the control unit 210, the vibration sensor 230 being used to detect vibration signals; wherein the control unit 210 is used to control the light-emitting element 220 so that it emits light or goes out according to the vibration signal.

[0030] In this embodiment, the control unit 210, the light-emitting element 220, and the vibration sensor 230 are all integrated on the circuit board 240 and electrically connected. The vibration sensor 230 is responsible for detecting the puck's movement state and sends a signal to the control unit 210 when the puck is struck or moved. The control unit 210 controls the switching state of the light-emitting element 220 based on the received vibration signal to achieve light emission or deactivation. By combining the vibration sensor 230 and the control unit 210, the puck can be automatically illuminated during movement, which significantly enhances the visual impact of the game and the user experience, making the gameplay more dynamic and engaging.

[0031] Some of the pucks are equipped with a one-time power supply and must be replaced as a whole when the power is used up, which not only increases usage costs but also generates more waste, which is not compatible with the concept of environmental protection.

[0032] In one embodiment, the puck comprises a charging copper column 250, wherein the charging copper column 250 is electrically connected to the power source 300 in order to charge the power source 300.

[0033] If the puck doesn't have enough power, in this embodiment it's only necessary to connect the external charger to the charging copper column. The current can then flow smoothly through the copper column to the power source device, and the puck can be returned to its operating state once charging is complete. Using a copper column for charging is more durable than a standard charging port and makes the puck more stable overall.

[0034] The durability of the copper column makes the overall structure of the puck safer, reduces malfunctions caused by damage to the charging components, and extends the puck's lifespan; at the same time, the repeated charging of the puck allows it to continue functioning, thus avoiding resource consumption and waste generation through frequent puck replacement, thereby implementing the concept of environmental protection and reducing long-term usage costs.

[0035] There are two charging copper columns 250 that are electrically connected to the power source 300 to charge the power source 300, making charging more convenient, stable and fast; here the charging copper columns 250 are seamlessly connected to the main body, so no additional adhesive filling is required.
