[0031] Please refer to Figure 1a and Figure 1b , Figure 1a and Figure 1b It is a schematic diagram of a smart chess and card table 100, which includes a shuffling cavity 110. After the chess and cards are stored in the shuffling cavity 110, the smart chess and card table 100 can automatically perform shuffling and card coding actions.

[0032] In order to reduce the impact of the noise generated by the smart chess and card table 100 when shuffling and stacking cards on the user, this embodiment provides a noise reduction device 200, please refer to Figure 2 The noise reduction device 200 may include a first working state detection component 210, an audio emission component 220 and a signal processing component 230.

[0033] The first working state detection component 210 and the audio emission component 220 can be arranged in the shuffling chamber 110 of the smart chess and card table 100.

[0034] The signal processing component 230 is respectively connected to the first working state detection component 210 and the audio emission component 220. The audio emission component 220 can be used to emit an audio signal, for example, the audio emission component 220 can be a speaker.

[0035] The signal processing component 230 is used to determine whether the smart chess and card table 100 is in the first working state through the first working state detection component 210, and the first working state at least includes a shuffling state and a card stacking state. The signal processing component 230 is also used to control the audio emission component 220 to emit a corresponding active noise reduction audio when detecting that the smart chess and card table 100 is in the first working state.

[0036] In this embodiment, active noise reduction technology can be used to determine active noise reduction audio with equivalent amplitude and opposite phase based on the noise audio generated by the smart chess and card table 100 when shuffling and stacking cards. By playing the active noise reduction audio, the noise audio can be offset to a certain extent, thereby achieving a noise reduction effect.

[0037] Since the time spent on shuffling and stacking cards is relatively small during the chess and card game process, continuously performing active noise reduction in the non-shuffling and non-stacking states may affect the user's normal voice communication and increase unnecessary power consumption. Therefore, in this embodiment, the signal processing component 230 cooperates with the first working state detection component 210 to perform active noise reduction operations only when the smart chess and card table 100 is detected to be in the first working state, thereby avoiding the influence of active noise reduction frequency in the non-first working state and reducing power consumption.

[0038] In some possible implementations, the smart chess and card table 100 includes at least four user positions, and the noise reduction device 200 includes at least four audio emission components 220 corresponding to the at least four user positions, respectively. In this way, noise can be eliminated in a targeted manner at the position where the user is located.

[0039] In some scenarios, when active noise reduction is performed, it is usually necessary for the noise audio collection component 240 to collect noise audio, and then the signal processing component 230 determines the corresponding active noise reduction frequency according to the collected noise audio. Since the noise audio generated when coding and shuffling cards usually has relatively fixed audio characteristics (such as relatively fixed frequency), in some possible implementation methods, please refer to Figure 3 , the first working state detection component 210 includes a noise audio collection component 240 disposed in the shuffling chamber 110. The signal processing component 230 is used to control the audio emission component 220 to send the corresponding active noise reduction audio according to the noise audio collected by the noise audio collection component 240. That is to say, in this scenario, the noise audio collection component 240 can be reused as the first working state detection component 210, and the signal processing component 230 determines whether the smart chess and card table 100 is in the first working state according to the audio collected by the noise audio collection component 240, and when the smart chess and card table 100 is in the first working state, the corresponding active noise reduction audio is determined according to the noise audio collected by the noise audio collection component 240.

[0040] Furthermore, due to the different internal structures of the smart chess and card table 100, the noise audio generated at different positions may be different, so in this embodiment, the noise reduction device 200 may include multiple noise audio collection components 240 and audio emission components 220 arranged at different positions, and the signal processing component 230 is used to control each audio emission component 220 to send corresponding active noise reduction audio according to different noise audio collection components 240. In this way, the noise audio at different positions can be more targeted.

[0041] In some scenarios, when the smart chess and card table 100 performs the automatic shuffling or card stacking action, it usually enables the shuffling drive component 120 or the card stacking drive component 130 to drive the chess and cards to move. Therefore, in another possible implementation, please refer to Figure 4 The first working state detection component 210 may include a level detection component 250, and the level detection component 250 is connected to the shuffling drive component 120 or the card coding drive component 130 of the smart chess and card table 100. The signal processing component 230 is used to determine the first working state of the smart chess and card table 100 according to the working voltage of the shuffling drive component 120 or the card coding drive component 130 detected by the level detection component 250.

[0042] For example, when the signal processing component 230 detects through the level detection component 250 that the shuffling drive component 120 or the coding drive component 130 starts working, it can be determined that the smart chess and card table 100 is in the first working state, so the signal processing component 230 can control the audio transmission component 220 to transmit the corresponding active noise reduction audio to offset the noise audio generated at this time.

[0043] In some possible implementations, the smart chess and card table 100 may also have an automatic dice rolling function and related components, so please refer to Figure 5 , the noise reduction device 200 may further include a second working state detection component 260, and the second working state detection component 260 is connected to the signal processing component 230. The signal processing component 230 is also used to determine whether the smart chess and card table 100 is in a second working state through the second working state detection component 260, and the second working state includes a dice rolling state. The signal processing component 230 is also used to control the audio emission component 220 to emit a corresponding active noise reduction audio when it is determined that the smart chess and card table 100 is in the second working state.

[0044] Furthermore, in this embodiment, the noise audio collection component 240 can be reused as the second working state detection component 260 to determine whether the smart chess and card table 100 is in the second working state together with the signal processing component 230. In this embodiment, a special level detection component 250 can also be set to connect with the dice driving component of the smart chess and card table 100, and determine whether the smart chess and card table 100 is in the second working state according to the level of the dice driving component.

[0045] In some possible implementations, the noise reduction device 200 further includes a storage component, and the signal processing component 230 is further used to control the audio emission component 220 to play prompt audio or advertising audio according to the audio data stored in the storage component. Exemplarily, in this embodiment, the audio emission component 220 can also be used to play prompt audio during chess and card games, or to play commercial advertising audio during the intervals of chess and card games.

[0046] In some possible implementations, different users have different tolerances for the noise audio generated during the automatic shuffling and stacking process, and it is not ruled out that some users may think that the sound generated during shuffling and stacking is also part of the chess and card game. Therefore, in this embodiment, the noise reduction device 200 may also include a startup control component, which is connected to the signal processing component 230, and the signal processing component 230 is also used to determine whether to enable the function of playing the active noise reduction audio in response to the user's operation on the startup control component. The startup control component allows users to choose whether to enable the active noise reduction function.

[0047] In some possible implementations, the noise reduction device 200 further includes a sound-absorbing and noise-reducing interlayer disposed on the inner wall of the shuffling cavity 110. Usually, active noise reduction is for low-frequency noise with relatively low frequency and relatively strong penetration, while for high-frequency noise with relatively high frequency and relatively weak penetration, a sound-absorbing and noise-reducing interlayer can be disposed on the inner wall of the shuffling cavity 110 for absorption and elimination, and the sound-absorbing and noise-reducing interlayer can include flexible sound-insulating materials such as sponge and rubber.

[0048] In addition, this embodiment also provides a smart chess and card table, which may include the noise reduction device provided in this embodiment.

[0049] In summary, the present application provides a noise reduction device and a smart chess and card table, wherein the signal processing component of the noise reduction device detects the first working state of the smart chess and card table according to the first working state detection component, and controls the audio transmitting component to emit corresponding active noise reduction audio according to the first working state, so that active noise reduction audio can be emitted when the smart chess and card table performs automatic shuffling or coding, thereby offsetting the noise generated in the process of automatic shuffling and coding, and reducing the impact of noise on user experience.

[0050] The functional modules in the various embodiments of the present application may be integrated together to form an independent part, or each module may exist independently, or two or more modules may be integrated to form an independent part.
