Description

Technical Field

[0001] The present invention relates to the technical field of card launchers, and particularly to an NFC card launcher. Background Art

[0002] As one of the popular game categories in the market, card games have long been favored by many players. Traditional card games usually use paper cards as carriers, and print picture information on the surface of the cards. During the game, players mainly understand the information represented by the cards by visually observing the picture content on the cards, and operate and compete according to the established game rules. However, this traditional card game mode has many significant defects, seriously restricting its further development and the improvement of the player experience.

[0003] The functions of traditional card games are limited to the content conveyed by the picture information printed on the surface of the cards. The cards only serve as a static information display tool, lacking diversified function expansion. For example: during the game, players can only make game decisions based on the fixed patterns and texts on the cards, and cannot realize more complex and rich gameplays. This functional limitation makes traditional card games seem powerless in the face of the increasingly diversified and personalized player needs, and it is difficult to attract the long-term attention and participation of more players.

[0004] In addition, the interactivity of traditional card games mainly relies on face-to-face communication and operation between players. Players interact in the game by directly exchanging cards, verbally communicating strategies, etc. However, this interaction method is restricted by time and space. Players must play the game at the same place and at the same time, greatly limiting the participation scope and flexibility of the game. In addition, due to the lack of effective technical support, the interaction form between players is relatively single, and it is difficult to achieve a deeper and wider interactive experience, unable to meet the needs of modern players for social interaction and game diversity.

[0005] Moreover, paper cards themselves do not have an electronic storage function, which results in the inability of traditional card games to achieve network interaction. In today's digital age, players have higher expectations for the convenience, real-time nature, and sociality of games. Since traditional card games cannot be connected to the network, players cannot conduct real-time battles, communicate, and share game experiences with other players, greatly reducing the fun and attractiveness of the games. At the same time, the lack of game competitive attributes also makes traditional card games significantly insufficient in stimulating players' competitive awareness and sense of achievement.

[0006] In summary, the traditional card games have many problems in terms of functions, interactivity, and participants' experience, and can no longer meet the development of the modern game market and the needs of players. Therefore, it is of great practical significance and market value to develop a card game method with innovative functions, high interactivity, and excellent experience. Summary of the Invention

[0007] The object of the present invention is to overcome the deficiencies of the prior art and provide an NFC card emitter.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions:

[0009] An embodiment of the present invention provides an NFC card emitter, including: a housing, a main control board is arranged inside the housing, an NFC sensor is arranged on the main control board, at least one NFC card placement area is opened on the housing, and the placement area corresponds to the NFC sensor. A card holder for supporting the NFC card is further arranged below the placement area.

[0010] In a specific embodiment, a semi-open baffle is arranged at the placement area of the housing. The card holder is slidably connected to the housing, and the thickness of the NFC card is greater than the gap between the card holder and the baffle.

[0011] In a specific embodiment, an elastic member is further arranged at the bottom of the card holder.

[0012] In a specific embodiment, a touch button is further arranged on the side of the main control board where the NFC sensor is located. When the NFC card is inserted into the placement area, the card holder moves downward to press the touch button.

[0013] In a specific embodiment, a magic light is further arranged around the touch button on the main control board, and a light guide cover corresponding to the magic light is arranged on the housing.

[0014] In a specific embodiment, a speaker is further arranged on the side of the housing, and the speaker is electrically connected to the main control board.

[0015] In a specific embodiment, the main control board further has a Bluetooth module.

[0016] In a specific embodiment, the housing further has a display screen, and the display screen is electrically connected to the main control board.

[0017] In a specific embodiment, the housing further has a changeover switch, the changeover switch is electrically connected to the main control board, and the changeover switch has a plurality of buttons.

[0018] In a specific embodiment, a wristband is further arranged at the bottom of the housing.

[0019] The NFC card transmitter of the present invention has the following beneficial effects compared with the prior art: when an NFC card is placed on the corresponding placement area of the transmitter housing, the NFC sensor can quickly interact with the card for data. This means that players are no longer restricted to playing games in the same location. With the help of NFC communication, it is easy to achieve remote or cross-regional transmission and interaction of card information, enhancing the interactivity and convenience of the game and meeting the needs of modern players for game socialization and flexibility. In addition, the NFC sensor on the main control board can quickly read the rich information stored in the card, such as card attributes, skills, character backgrounds, etc., and transmit this information to the game terminal in real time. This makes the game process more diverse, and players can formulate diverse strategies based on different card information, increasing the strategic nature and depth of the game. At the same time, combined with the networking function, players can also obtain more dynamic game content, such as limited-time events, special tasks, etc., further enhancing the fun and attractiveness of the game and bringing a brand-new game experience to players.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0029] In the present invention, unless otherwise clearly defined and limited, the terms "mounted", "connected", "coupled", "fixed", etc. should be construed in a broad sense. For example, it may be a connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements.

In this specification, the schematic expressions of the above terms should not be understood as necessarily referring to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

[0032] Referring to Figures 1 to 3 In the specific embodiment shown, the present invention discloses an NFC card transmitter, including: a housing 10, a main control board 20 is provided inside the housing 10, an NFC sensor 30 is provided on the main control board 20, at least one NFC card 150 placement area is opened on the housing 10, and the placement area corresponds to the NFC sensor 30, and a card holder 40 for supporting the NFC card 150 is further provided below the placement area.

[0033] Specifically, by burning the information of the card into the NFC chip while printing, the high integration of the visual information (printed content) and the electronic information (stored content in the NFC chip) of the card is realized to obtain the NFC card 150. When a player obtains a card, they can intuitively understand the basic features of the card through the printed pattern and quickly read the detailed information in the chip through the NFC sensor 30, greatly improving the efficiency of information acquisition. In addition, the NFC technology has the characteristic of fast response. When the NFC card 150 is placed in the placement area of the transmitter, the NFC sensor 30 can establish communication with the chip in the card in an extremely short time and read the information therein, which enables the player to quickly obtain the card information during the game process, speeds up the game rhythm, reduces the waiting time, and improves the fluency and experience of the game. In addition, one of the advantages of using NFC technology is that it does not require separate power supply for the card while storing information, which means that the NFC card 150 does not need to be equipped with a power supply device such as an internal battery, thus simplifying the design and manufacturing process of the card and reducing the cost. At the same time, it also avoids the inconvenience caused by battery power depletion or battery replacement, improving the convenience and reliability of the card's use. Since no power supply is required, the information of the NFC card 150 can be stored stably in the chip for a long time without information loss or damage caused by battery problems. Players can save and use these cards for a long time without worrying about the card being unable to be used normally due to power problems, extending the service life of the card.

[0034] Among them, the combination of the transmitter and the NFC card 150 provides more possibilities for game development. Game developers can design more diverse and innovative gameplay based on the rich information stored in the NFC card 150. For example: By combining and interacting with different card information, special game events or skill effects can be triggered, increasing the strategic and interesting nature of the game. Additionally, with the help of NFC technology and network connection, the transmitter can achieve cross-platform game interaction. Players can not only play against or cooperate with other players locally, but also communicate and compete with players globally through the Internet, expanding the social scope and influence of the game.

[0035] That is to say, when the NFC card 150 is placed in the corresponding placement area on the transmitter housing 10, the NFC sensor 30 can quickly perform data interaction with the card. This means that players are no longer limited to playing games in the same location. With the help of NFC communication, the transmission and interaction of card information over long distances or across regions can be easily achieved, enhancing the interactivity and convenience of the game and meeting the modern players' needs for game socialization and flexibility. In addition, the NFC sensor 30 on the main control board 20 can quickly read the rich information stored in the card, such as card attributes, skills, character backgrounds, etc., and transmit this information to the game terminal in real time. This makes the game process more diverse. Players can formulate diverse strategies based on different card information, increasing the strategic nature and depth of the game. At the same time, combined with the networking function, players can also obtain more dynamic game content, such as limited-time events, special tasks, etc., further enhancing the interesting nature and attractiveness of the game and bringing a brand-new game experience to players. Additionally, the card holder 40 provided below the placement area not only provides stable support for the card but also ensures stable and accurate data connection between the card and the NFC sensor 30.

[0036] In one embodiment, the housing 10 is also provided with a semi-open baffle 50 at the placement area. The card holder 40 is slidably connected to the housing 10, and the thickness of the NFC card 150 is greater than the gap between the card holder 40 and the baffle 50.

[0037] Specifically, when the NFC card 150 is inserted into the placement area, since the thickness of the NFC card 150 is greater than the gap between the card holder 40 and the baffle 50, the card holder 40 presses down on the main control board 20 to form a trigger. After the main control board 20 receives the trigger signal, it activates the NFC sensor 30. More specifically, the card holder 40 is usually made of a material with a certain strength and toughness, such as plastic. Its shape should be adapted to the shape of the placement area and should be designed into a structure that is convenient for sliding. For example, slide rails or protrusions can be provided on both sides of the card holder 40 to cooperate with the corresponding chutes or grooves inside the housing 10. At the position corresponding to the placement area inside the housing 10, chutes or grooves that match the slide rails or protrusions of the card holder 40 are machined. The size and precision of the chutes or grooves should be strictly controlled to ensure that the card holder 40 can slide smoothly therein, and at the same time, it is necessary to ensure that the card holder 40 does not loosen or fall off during the sliding process. The card holder 40 is installed inside the housing 10 so that its slide rails or protrusions are accurately embedded in the chutes or grooves, realizing the sliding connection between the card holder 40 and the housing 10.

[0038] A corresponding trigger circuit is designed on the main control board 20. This circuit should include a trigger element such as a pressure sensor or a contact switch. The position of the trigger element should be accurately set on the path where the card holder 40 presses down, ensuring that when the card holder 40 is squeezed and pressed down by the NFC card 150, it can accurately press the trigger element. When the card holder 40 presses down on the trigger element on the main control board 20 due to the insertion of the NFC card 150, the trigger element generates an electrical signal. This electrical signal is transmitted to the main control chip through the circuit inside the main control board 20 (the main control board 20 is provided with a main control chip). After the main control chip receives the trigger signal, it starts the NFC sensor 30 according to the pre-set program, making it start to work and prepare to read the information in the NFC card 150.

[0039] That is to say, by setting the semi-open baffle 50, the slidably connected card holder 40, and precisely controlling the gap between the card holder 40 and the baffle 50, it is ensured that only when the NFC card 150 is correctly inserted into the placement area, the card holder 40 will press down on the main control board 20 to form a trigger due to the thickness of the card being greater than the gap. This design avoids false triggers caused by misoperations or other foreign objects entering the placement area, improving the accuracy and reliability of the trigger mechanism. Additionally, when the main control board 20 does not receive a trigger signal, the NFC sensor 30 is in a closed state and does not consume electrical energy. Only when the NFC card 150 is inserted and triggers the main control board 20, the NFC sensor 30 will start working. This on-demand startup design effectively reduces the overall power consumption of the transmitter, extends the usage time of the battery unit 130, and improves energy utilization efficiency. Moreover, the design of the semi-open baffle 50 enables players to easily insert the NFC card 150 into the placement area without complex operation steps. At the same time, the slidably connected card holder 40 can automatically adapt to the insertion of the card and smoothly press down on the main control board 20 under the action of the card, providing players with a simple and convenient operation experience. Since the card holder 40 is slidably connected to the housing 10 and the gap is precisely controlled, during the insertion of the card and the downward movement of the card holder 40, the smoothness and stability of the movement can be ensured, which helps to reduce the impact on the trigger mechanism and the information reading of the NFC sensor 30 caused by mechanical vibration or shaking, improving the stability and reliability of the transmitter operation.

[0040] In one embodiment, an elastic member is further provided at the bottom of the card holder 40.

[0041] Specifically, according to the overall design requirements of the transmitter, the space size, and the required elastic force, a suitable spring is selected as the elastic member. A dedicated installation structure is designed at the bottom of the card holder 40 to fix the spring. A cylindrical groove can be provided at the bottom of the card holder 40, the diameter of the groove is slightly larger than the outer diameter of the spring, and the depth can accommodate a part of the length of the spring in the natural state to ensure that the spring can be stably installed on the card holder 40. When the NFC card 150 is inserted into the placement area, the card will squeeze the card holder 40, causing the card holder 40 to move downward. At this time, the spring is compressed and generates an upward elastic force. As the card continues to be inserted, the elastic force of the spring gradually increases, and finally, the NFC card 150 is tightly fixed between the card holder 40 and the baffle 50, ensuring the stability of the card's position in the transmitter and avoiding affecting the reading of the card information by the NFC sensor 30 due to shaking during the game. When the NFC card 150 is taken out, the spring is no longer squeezed by the card, and the elastic potential energy stored in it begins to be released. The elastic force of the spring will push the card holder 40 upward to return the card holder 40 to its initial position, preparing for the next insertion of the NFC card 150.

[0042] That is to say, the elastic force of the spring can tightly fit the NFC card 150 between the card holder 40 and the baffle 50, reducing the shaking of the card in the transmitter. During the game, even if the transmitter is slightly bumped or vibrated, the card can maintain a relatively stable position, ensuring that the NFC sensor 30 can accurately read the information in the card, improving the accuracy and reliability of data reading. In addition, since the spring has a certain elasticity and compression stroke, it can adapt to NFC cards 150 of different thicknesses. Whether it is a standard-thickness card or a card with a certain thickness deviation due to production processes, etc., the spring can adjust through its own elastic force to firmly fix the card in a suitable position, enhancing the versatility of the transmitter. In addition, when inserting and removing the NFC card 150, the elastic force of the spring can provide a natural damping feeling, making the operation smoother. When inserting the card, the spring is gradually compressed, giving the player a clear feedback, letting the player know that the card is being correctly fixed; when removing the card, the spring pushes the card holder 40 to reset, facilitating the player's next operation and improving the player's usage experience. Compared with the card holder 40 without an elastic component, the card holder 40 with a spring is more stable during movement, reducing the problem of unsmooth operation caused by jamming. The player can feel a smoother operation process when inserting and removing the card, further enhancing the player's satisfaction with the transmitter.

[0043] In one embodiment, a touch button 60 is further provided on the side of the main control board 20 where the NFC sensor 30 is located. When the NFC card 150 is inserted into the placement area, the card holder 40 presses down on the touch button 60.

[0044] Specifically, the touch button 60 is connected to the trigger signal processing circuit on the main control board 20. When the touch button 60 is pressed, the internal contacts thereof will close, generating an electrical signal. This electrical signal is transmitted to the trigger signal processing circuit on the main control board 20. The trigger signal processing circuit on the main control board 20 will perform processing such as filtering, amplifying, and shaping on the received electrical signal to eliminate interference signals and transmit the processed signal to the main control chip. After receiving a valid trigger signal, the main control chip will start the NFC sensor 30 according to a pre-set program, enabling it to start working and prepare to read the information in the NFC card 150.

[0045] That is to say, triggering the NFC sensor 30 by directly pressing the touch button 60 through the lower part of the card slot 40 has higher physical triggering accuracy compared with some other triggering methods based on electronic signal detection. This mechanical triggering method is not affected by factors such as electromagnetic interference. As long as the card slot 40 can accurately press the touch button 60, a triggering signal can be reliably generated to ensure that the NFC sensor 30 can be started in time when needed. Since the touch button 60 needs a certain amount of pressure to be triggered, in the case where no NFC card 150 is inserted, false triggering signals will not be generated due to slight external vibrations or interference, which greatly improves the reliability of the triggering mechanism and reduces the frequent startup of the device and energy waste caused by false triggering.

[0046] In one embodiment, a magic light 70 is further provided around the touch button 60 on the main control board 20, and the housing 10 is provided with a light guide cover 80 corresponding to the magic light 70.

[0047] Specifically, according to the installation position of the magic light 70 and the structure of the housing 10, the shape and size of the light guide cover 80 are designed. The main function of the light guide cover 80 is to evenly guide the light emitted by the magic light 70 to the outside of the housing 10 to improve the utilization rate and display effect of the light. The light guide cover 80 can be made of transparent or semi-transparent materials, such as acrylic, polycarbonate, etc. When designing, the shapes of the light incident surface and the light exit surface of the light guide cover 80, as well as the internal light guide structure, such as prisms, reflection surfaces, etc., should be considered to optimize the light propagation path. In the program of the main control chip, the logic code for controlling the lighting of the magic light 70 is written. When the NFC sensor 30 is started, the main control chip will detect the corresponding start signal, and then through the control pin of the magic light 70, the magic light 70 will light up simultaneously. The lighting color, brightness and flashing mode of the magic light 70 can be set according to actual needs. For example, it can be set to be constantly on, breathing light effect or fast flashing, etc., to play different prompting roles.

[0048] That is to say, when the NFC sensor 30 is activated, the magic lights 70 light up simultaneously, providing players with an intuitive visual cue. Players do not need to confirm whether the NFC sensor 30 has been activated through other means (such as checking the device display screen 100 or listening to sound cues), but only need to observe the lighting state of the magic lights 70, which improves the convenience and efficiency of operation. In addition, the magic lights 70 can emit lights of multiple colors and can achieve different flashing effects, creating a unique atmosphere for the transmitter. In the game, the creation of this atmosphere can increase the fun and immersion of the game and enhance the player's gaming experience. In addition, the light guide cover 80 evenly guides the light of the magic lights 70 to the outside of the housing 10, giving the transmitter a unique lighting effect in appearance. Among many similar devices, this transmitter with the magic lights 70 cue is easier for players to identify and remember, improving the recognition and market competitiveness of the device.

[0049] In one embodiment, a speaker 90 is further provided on the side of the housing 10, and the speaker 90 is electrically connected to the main control board 20.

[0050] Specifically, when the NFC sensor 30 is activated, the speaker 90 emits a sound effect, providing players with immediate auditory feedback. Combining with the magic lights 70 cue mentioned above, the sound effect cue of the speaker 90 and the visual cue are combined to bring players a multi-sensory interaction experience. This multi-sensory experience can increase players' attention and participation in the device and improve players' satisfaction with use. In addition, in addition to emitting a sound effect when the NFC sensor 30 is activated, more sound effect functions can be achieved through programming. For example: when the NFC card 150 is successfully or unsuccessfully read, the speaker 90 can emit different sound effects for cueing; in the game, corresponding sound effects can also be played according to different game plots to increase the fun and immersion of the game. The unique sound effect can also become a brand feature of the device. By designing a recognizable sound effect, players can associate with the corresponding brand when they hear the sound effect, improving the popularity and reputation of the brand.

[0051] In one embodiment, the main control board 20 is further provided with a Bluetooth module.

[0052] Specifically, by reading the NFC badge of the other party through the NFC sensor 30, the Bluetooth mac address of the other party's transmitter can be obtained and Bluetooth can be automatically connected, so that the two parties can interact and compete. That is, through the Bluetooth module, interaction between two transmitters can be achieved, and a mobile phone can also be connected to upload data; in addition, a send button 140 is further provided on the housing 10 to send the read card information, and then the two-party battle function is realized.

[0053] More specifically, in the program of the main control chip, write a reading program for the NFC sensor 30. When the NFC sensor 30 detects that the other party's NFC badge is inserted or approaching, start the reading operation. Through the communication protocol between the NFC sensor 30 and the badge, read the information stored in the badge, which includes the Bluetooth MAC address of the other party's transmitter. After reading the data containing the Bluetooth MAC address, the main control chip parses the data and extracts the valid Bluetooth MAC address. Store the extracted Bluetooth MAC address in the memory of the main control chip, such as EEPROM or Flash memory, for subsequent Bluetooth connection operations. In the program of the main control chip, write the logic code for automatic Bluetooth connection. When the Bluetooth MAC address of the other party is successfully obtained, the main control chip controls the Bluetooth module to initiate a connection request. The connection request contains relevant information of the local Bluetooth module, such as device name, service UUID, etc. During the connection process, the main control chip monitors the Bluetooth connection status in real time. If the connection is successful, a Bluetooth communication link can be established between the two transmitters for data interaction; if the connection fails, the main control chip can retry according to the preset strategy, such as waiting for a period of time and then initiating a connection request again, or prompting the player to re-place the NFC badge.

[0054] In addition, develop a mobile application program that is compatible with the transmitter. This application program needs to have Bluetooth communication capabilities and be able to search for and connect to the Bluetooth module of the transmitter. At the same time, the application program should design a reasonable player interface to facilitate players to operate and view data. Develop a data upload protocol between the transmitter and the mobile phone. Specify rules such as the format, content, and transmission timing of data upload. For example: The transmitter can regularly upload relevant data during the game process (such as scores, operation records, etc.) to the mobile application program. The mobile application program parses and stores the received data and can provide functions such as data statistics, analysis, and sharing.

[0055] In addition, design a sending button 140 on the housing 10 and electrically connect the button to the main control board 20 through a wire. In the program of the main control chip, write the function code for the sending button 140. When the player presses the sending button 140, the main control chip detects the button press signal, then reads the previously stored card information (including the information of the other party read from the NFC badge, etc.), encapsulates the read card information according to the predetermined communication protocol, and sends it to the other party's transmitter through the Bluetooth module, thereby realizing the battle function between the two parties.

[0056] That is to say, by using the NFC sensor 30 to read the other party's NFC badge to obtain the Bluetooth MAC address and automatically connect to the Bluetooth, the connection process between the two transmitters is greatly simplified. Players do not need to manually perform Bluetooth pairing and connection operations. They only need to bring the NFC badge close to the transmitter to quickly establish a connection and enter the interactive competition state, improving the convenience and fluency of the game. In addition, the Bluetooth module enables real-time data interaction between the two transmitters, and both parties can timely obtain the operation information and game status of the other party, making the battle process more exciting and enhancing the interactivity and competitive experience. In addition, the transmitter can be connected to the mobile phone and upload data, providing players with richer data management and analysis functions. Players can view their game history records, score rankings and other information through the mobile phone application, and can also share the data to social platforms, increasing the social attributes of the device. At the same time, developers can understand the usage habits and needs of players by analyzing the data uploaded by players and optimize and improve the device. In addition, the sending button 140 provided on the housing 10 provides a convenient way for players to send card information. During the battle, players only need to press the sending button 140 to send relevant information to the other party. The operation is simple and intuitive, improving the operation efficiency and player experience of the game.

[0057] In one embodiment, the housing 10 is further provided with a display screen 100, and the display screen 100 is electrically connected to the main control board 20.

[0058] Specifically, there are multiple NFC sensors 30 on the transmitter. To solve the problem of mutual interference between multiple NFC sensing areas, a single-sensing area trigger method is adopted for the card reading method, and one sensing area is read each time a card is inserted. Because there are multiple NFC sensors 30, the superposition of card information can be realized. Different cards are inserted, and then the card information is saved to the memory of the main control board 20 for secondary processing, and more complex interactive attributes can be completed. After the NFC sensor 30 reads the card, the information of the card will be synchronously displayed on the display screen 100.

[0059] That is to say, by adopting the single induction area triggering method, only one induction area is read during each card insertion, effectively avoiding the mutual interference between multiple NFC sensors 30. This can ensure the accuracy and stability of each card reading operation, reduce the card reading errors or data loss caused by interference, and improve the reliability of the transmitter. In addition, during the operation process, players do not need to worry about the chaos caused by the simultaneous triggering of multiple induction areas. They only need to insert the card into the specified induction area to complete the card reading, making the operation simpler and more intuitive, and enhancing the players' usage experience. Moreover, the multiple NFC sensors 30 achieve the superposition of card information, enabling players to create various different effects and strategies by inserting different card combinations. For example: in a card battle game, players can select appropriate cards for superposition according to the situation of the opponent and their own tactical needs, increasing the strategic nature and depth of the game. The superposition function of card information brings more application scenarios for the transmitter. In addition to the game field, it can also be applied to the fields of education, training, etc. For example: in an educational scenario, different cards can represent different knowledge points or skills, and the comprehensive application and expansion of knowledge can be achieved by superposing card information. In addition, after the NFC sensor 30 reads the card, the information of the card can be promptly displayed on the display screen 100, providing real-time feedback for players. Players can immediately understand the attributes and effects of the card without obtaining information through other means (such as checking the instruction manual), improving the convenience and efficiency of the operation. The intuitive display function of the display screen 100 enhances the interaction between the player and the transmitter. Players can perform corresponding operations and make decisions based on the information displayed on the display screen 100, making the entire interaction process smoother and more natural. At the same time, the beautiful display interface can also attract the attention of players and improve the players' liking for the device.

[0060] In one embodiment, the housing 10 is further provided with a changeover switch 110, the changeover switch 110 is electrically connected to the main control board 20, and the changeover switch 110 is provided with a plurality of keys.

[0061] Specifically, the plurality of keys on the changeover switch 110 enable players to quickly switch different functions of the transmitter through simple key operations, improving the usage efficiency of the device, especially suitable for scenarios where functions need to be frequently switched, such as quickly switching different game modes or settings during the game process. In addition, by using the changeover switch 110 to achieve the switching of different functions, the transmitter can integrate more functions to meet the diverse needs of players. For example: in addition to the basic NFC sensing function, it can also integrate game modes, setting modes, Bluetooth connection modes, etc., making the transmitter a multifunctional device with rich functions.

[0062] In one embodiment, a wrist strap 120 is further provided at the bottom of the housing 10.

[0063] Specifically, according to the usage scenario of the transmitter, the target player group, and the cost budget, select a suitable type of wristband 120. Common types of wristbands 120 include Velcro wristbands 120, buckle wristbands 120, elastic stretch wristbands 120, etc. The Velcro wristband 120 is convenient to adjust and suitable for players with different wrist thicknesses; the buckle wristband 120 has a stable structure and a relatively traditional appearance; the elastic stretch wristband 120 has good fit and comfort and can automatically adapt to the wrist size.

[0064] That is to say, the transmitter is worn on the wrist through the wristband 120, so that the player does not need to hold the transmitter by hand, thus freeing both hands and facilitating the carrying of the transmitter while performing other activities. For example, in scenarios such as outdoor sports and game interactions, players can move their hands freely without worrying about the placement and carrying of the transmitter. In addition, the wristband 120 fixes the transmitter on the wrist, reducing the risk of the transmitter being lost. Compared with placing the transmitter in a pocket or bag, wearing it on the wrist is more intuitive and safe, and players can always sense the presence of the transmitter. In addition, the transmitter worn on the wrist is more stable during operation. Players can control the direction and angle of the transmitter through natural wrist movements, reducing operation errors caused by unstable handholding. For example, when performing operations such as NFC card 150 induction or Bluetooth connection, a stable wearing method can improve the accuracy and success rate of the operation. Since the transmitter is always near the player's wrist, players can perform operations quickly at any time, without having to search for and pick up the transmitter when needed, improving the operation response speed and efficiency.

[0065] In one embodiment, a rechargeable battery unit 130 is further provided inside the housing 10, and the battery unit 130 is electrically connected to the main control board 20 to supply power to the entire transmitter.

[0066] Specifically, the use of the rechargeable battery unit 130 enables the transmitter to work without an external power cord, and players can use the transmitter anytime and anywhere, without being restricted by the location of the power outlet. Whether in outdoor activities, game parties, or mobile office scenarios, etc., it is convenient to carry and use the transmitter, greatly improving the portability of the device. Compared with a transmitter using a disposable battery unit 130, the rechargeable battery unit 130 reduces the number of spare battery units 130 that players need to carry, reducing the burden on players. Players only need to carry a charger to charge the transmitter, which is convenient and environmentally friendly.

[0067] In one embodiment, the housing 10 is composed of an upper shell 11 and a lower shell 12 connected together. The card holder 40, the baffle 50, the light guide cover 80, the speaker unit 90, the display screen 100, the toggle switch 110, and the send button 140 are provided on the upper shell 11, and the battery unit 130 and the wristband 120 are provided on the lower shell 12.

[0068] Specifically, different components are respectively installed on the upper shell 11 and the lower shell 12, realizing the modular design of the transmitter. During the assembly process, the components on the upper shell 11 and the lower shell 12 can be installed and debugged separately, and then the upper shell 11 and the lower shell 12 are connected, improving the assembly efficiency. At the same time, when the transmitter fails, the upper shell 11 and the lower shell 12 can be conveniently disassembled to repair or replace the corresponding components, reducing the maintenance cost and difficulty. In addition, the components related to operations and displays such as the card slot 40, the baffle 50, the light guide cover 80, the speaker 90, the display screen 100, the changeover switch 110 and the sending button 140 are arranged on the upper shell 11, facilitating operation and observation by players; the components with larger volumes or requiring special installation such as the battery unit 130 and the wrist strap 120 are arranged on the lower shell 12, making the structure of the whole transmitter more reasonable and facilitating assembly and maintenance.

[0069] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
