DETAILED DESCRIPTION
[0008] Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. 5, a toy comprising the following; a control mainboard 1; a detection device 2 which is electrically connected to the control main board 1, wherein the detection device 2 is used to detect the actions of the toy 10; a storage device 3 which is electrically connected to the control mainboard 1, wherein the storage device 3 stores preset action data 31 and audio data 32; and a loudspeaker 4 which is electrically connected to the control mainboard 1; wherein, when the detection device 2 detects that the action of the toy 10 matches the preset action data 31, the control mainboard 1 controls the speaker 4 to play the audio data 32.
[0009] Through the structure described above, the sensing device 2 captures the action data of the toy 10 and transmits it to the control board 1. The control board 1 performs a pattern matching between this action data and the preset action data 31 in the storage device 3. If a match is found, it immediately retrieves the corresponding audio data 32 and plays the preset sound or music through the speaker 4. This design allows the toy 10 to provide intelligent acoustic responses to specific actions, which significantly enhances interactivity and enjoyment, thereby maintaining children's attention, stimulating their enthusiasm for play and physical activity, and improving their physical coordination and imitation skills through play.
[0010] In the present embodiment, the audio data 32 comprise a first audio recording and a second audio recording, which are distinct from each other. When the detection device 2 detects that the action of the toy 10 corresponds to the preset action data 31, the control board 1 controls the speaker 4 to play the first audio recording or the second audio recording at random. Of course, in the present embodiment, the toy 10 can also include other distinct audio recordings, such as a third audio recording, a fourth audio recording, etc.
[0011] With the structure described above, once the detection device 2 detects that the action of the toy 10 matches the preset action, the control board 1 randomly selects an audio recording from the audio data 32, which includes several different audio recordings, and plays it through the speaker 4. This design significantly increases the novelty and replayability of the toy 10, as users cannot predict which sound will be played next. This maintains curiosity and the urge to explore, effectively preventing boredom from repetitive feedback. The interaction becomes more surprising and entertaining, further stimulating children's enjoyment of the game.
[0012] In the present embodiment, the detection device 2 comprises a first sensor 21 and a second sensor 22. The first sensor 21 detects the angular velocity and changes in direction of the toy 10, while the second sensor 22 detects the linear acceleration and changes in gravity of the toy 10. In particular, the first sensor 21 is a gyroscope sensor and the second sensor 22 is an accelerometer. Of course, the second sensor 22 can be replaced by alternative sensors in other embodiments.
[0013] With the above structure, the toy 10 uses the gyroscope sensor to precisely detect its rotation angle and changes in direction, while simultaneously using the accelerometer to synchronously detect the speed of movement, the force of impact, and the angle of tilt. By integrating these two categories of dynamic data, the control mainboard 1 achieves a more comprehensive and accurate identification of the actual actions of the toy 10—for example, detecting whether the toy 10 is being shaken, spun, or thrown—thus ensuring the accuracy and reliability of action identification.
[0014] In the present embodiment, the toy 10 comprises a first preset mode and a second preset mode, wherein the first preset mode differs from the second preset mode. The preset action data 31 comprise a first preset action and a second preset action. The toy further comprises a switching device 50, which is used to switch the toy 10 to the first preset mode or the second preset mode.
[0015] In the present embodiment, the audio data 32 comprise a first audio recording. When the toy 10 is in the first preset mode, the first preset action is tossing and spinning the toy. When the detection device 2 detects that the toy 10 has been tossed and spun, the control board 1 controls the speaker 4 to play the first audio recording. In particular, the first audio recording is an audible announcement of the final number of rotations of the toy. After the toy 10 has been tossed and spun for a certain number of rotations, the control board 1 controls the speaker 4 to play the final number of rotations of the toy 10.The structure described above allows the gyroscope and accelerometer sensors to detect changes in acceleration when toy 10 is thrown into the air, as well as the angular velocity during its rotation around its axis in the air. The control board 1 calculates and records the total number of rounds in real time. Upon completion of the action, the control board 1 controls the speaker 4 to announce this final number of rounds. For example, if toy 10 is thrown upwards and rotates for two rounds, the number "two rounds" will be announced when it lands in the user's hand. This design integrates physical movement with instant audio feedback, creating a highly interactive play experience that encourages children's enthusiasm for movement and their desire for repeated challenges. To achieve a higher number of rounds, children will intrinsically perform repeated throwing exercises.In doing so, they naturally train their physical coordination skills.
[0016] In the present embodiment, the audio data 32 further includes a second audio recording and a third audio recording. When the toy 10 is in the second preset mode, the second preset action is tossing and spinning the toy 10 for one rotation. When the detection device 2 detects that the toy 10 has been tossed and spun for one rotation, the control board 1 directs the speaker 4 to play the second or third audio recording at random. Of course, in other embodiments, the second preset action, namely tossing and spinning, can trigger the control board 1 to direct the speaker 4 to play the second or third audio recording at random.
[0017] Specifically, the second audio recording is a first piece of music with a first preset duration, while the third audio recording is a second piece of music with a second preset duration. The first and second preset durations differ from each other, and the first and second pieces of music differ from each other. The second and third audio recordings are each pieces of music with drum rhythms; the first and second preset durations are each within 30 seconds of each other.
[0018] Furthermore, the audio data 32 also includes a fourth audio recording. When the toy 10 is in the second preset mode, and the detection device 2 detects that the toy 10 has been tossed and spun for one rotation, the control board 1 controls the speaker 4 to play one of the second, third, and fourth audio recordings at random. Specifically, the second audio recording is a first piece of music with a first preset duration, the third audio recording is a second piece of music with a second preset duration, and the fourth audio recording is a third piece of music with a third preset duration. The first preset duration, the second preset duration, and the third preset duration are different from each other, and the first piece of music, the second piece of music, and the third piece of music are different from each other.The second audio recording, the third audio recording and the fourth audio recording are each a piece of music with drum rhythms; the first preset duration, the second preset duration and the third preset duration are each within 30 seconds.
[0019] According to the above structure, when the toy 10 is in the second preset mode, the combination of detection by the gyroscope sensor and the accelerometer, upon detecting that the toy 10 has been thrown into the air and spun for one rotation, triggers the control mainboard 1 to control the speaker 4 in such a way that it randomly plays the first, second, or third audio recording. The first, second, and third audio recordings are each a piece of music with different drum rhythms and a maximum duration of 30 seconds. For example, the first audio recording could be a 15-second piece of music with drum rhythms, the second audio recording could be a 20-second piece of music with drum rhythms, and the third audio recording could be a 25-second piece of music with drum rhythms.The first, second, and third audio recordings all end with an "explosion" sound effect. This mode can be used in passing games based on the principle of "stop music." After triggering toy 10 and playing the first, second, or third piece of music, the toy can be passed between players by throwing it horizontally. The random duration prevents players from predicting when the sound will stop, significantly improving fairness and immersion in the game. The short, 30-second music tracks ensure a fast-paced game. The drum rhythm creates a tense yet exciting atmosphere that not only sharpens children's reflexes and teamwork but also provides a dynamic, interactive entertainment option for group events, thus significantly promoting social engagement.
[0020] In the present embodiment, the toy 10 further comprises a third preset mode, wherein the preset action data 31 further comprises a third preset action, and wherein the audio data 32 further comprises a fifth and a sixth audio recording, which are distinct from each other; when the toy 10 is in the third preset mode, the third preset action is shaking the toy 10. When the detection device 2 detects that the toy 10 has been shaken, the control board 1 directs the speaker 4 to play the fifth or sixth audio recording at random. Of course, the toy 10 can include several different audio recordings, such as a seventh audio recording, an eighth audio recording, etc., and the toy 10 can play different audio recordings at random.
[0021] In particular, the fifth audio recording is one of natural ambient sounds, simulated animal sounds or simulated human voices; the sixth audio recording is also one of natural ambient sounds, simulated animal sounds or simulated human voices.
[0022] According to the above structure, when the toy 10 is in the third preset mode and the toy 10's gyroscope and accelerometer detect that it has been shaken, the control board 1 randomly selects the fifth or sixth audio recording from the storage device 3, which is played through the speaker 4. These recordings might include wind and rain sounds, cat or dog barking, or emotional expressions such as "You shake me, shake me, shake me until I get dizzy," imitating animals or characters. Simple shaking motions trigger vivid and varied ambient sounds or character simulations, allowing users to experience a wide range of random sounds.This not only increases the fun and unpredictability of the game, but also helps children to recognize natural phenomena and animal sounds while playing, which serves an early childhood educational purpose.
[0023] In the present embodiment, the switching device 50 comprises a gear switch 5 which is electrically connected to the main control board 1. The gear switch 5 has a release element 51 and comprises an initial position 511, a first position 512, and a second position 513. The toy 10 comprises a first preset mode and a second preset mode. When the release element 51 is moved from the initial position 511 to the first position 512, the toy 10 is in the first preset mode. When the release element 51 is moved from the first position 512 to the second position, the toy 10 is in the second preset mode.
[0024] In another embodiment, as in Fig. As shown in Figure 6, the gear switch 5 has a push-button element 52 and comprises a starting position 511, a first position 512, and a second position 513. The toy 10 includes a first preset mode and a second preset mode. When the push-button element 52 is pressed from the starting position 511 to the first position 512, the toy 10 is in the first preset mode. When the push-button element 52 is pressed from the first position 512 to the second position, the toy 10 is in the second preset mode. The arrangement of a physical push-button switch provides users with an alternative, clear, simple, and reliable method for switching between the modes.
[0025] In the present embodiment, the toy 10 further includes a third preset mode. When the release element 51 is quickly moved directly from the initial position 511 to the second position, the toy 10 is in the third preset mode. The above structure allows a mechanical gear switch 5 with an initial position 511, a first position 512, and a second position to enable users to select modes by actuating this physical release element 51: A conventional move to the first position 512 activates the first preset mode, while a further move to the second position activates the second preset mode. The specific gesture of quickly moving the switch directly from the initial position 511 to the second position triggers the hidden third preset mode.The physical trigger switch offers users a clear, simple, and reliable method for switching between modes. At the same time, the ingenious "quick-flip trigger for bent mode" significantly enhances the sense of discovery and mystery surrounding the product, stimulating children's curiosity and drive to explore. This considerably improves the interactivity and playability of the toy.
[0026] In the present embodiment, the toy further comprises an installation housing 6 and a battery assembly 7, wherein the main control board 1, the sensing device 2, the loudspeaker 4, the storage device 3, and the battery assembly 7 are each arranged in the installation housing 6; wherein the toy further comprises a toy body 101, which is a flexible toy body 101, the toy body 101 being provided with a receiving cavity 1011, and wherein the installation housing 6 is enclosed in the receiving cavity 1011. The toy body 101 is further provided with an opening 1012, which is connected to the receiving cavity 1011 and serves for inserting or removing the installation housing 6. The two ends of the opening 1012 are connected to each other by hook-and-loop fasteners or, alternatively, by zippers, snap fasteners, or similar means.
[0027] The above structure fully integrates and encapsulates the control board 1, the sensing device 2, the speaker 4, the storage device 3, and the battery assembly 7 within an independent installation housing 6. This housing is then embedded in the receiving cavity 1011 of the flexible plush toy body 101. The installation housing 6 provides protection for the electronic components and effectively protects the toy 10 from impacts caused by external pressure and drops, thus improving the product's durability and reliability. This structure integrates intelligent interactive functions into the traditional soft toy 10 without compromising its appealing appearance, thereby achieving enhanced intelligence and interactivity.
[0028] In the present embodiment, the toy further comprises a toy body 101, which has a croissant-shaped design. Legs 1013 are connected to the base of the toy body 101. In this embodiment, the unique "croissant" design significantly enhances the visual appeal of the toy 10, quickly wins the affection of children, and simultaneously stimulates associations with food and role-playing scenarios, thereby considerably increasing the fun and entertainment value of the toy.
[0029] In another embodiment, the preset action is the rotation of the toy 10. When the detection device 2 detects that the toy 10 has rotated to a first angle, the control board 1 controls the speaker 4 to play the first audio recording; when the detection device 2 detects that the toy 10 has rotated to a second angle, the control board 1 controls the speaker 4 to play the second audio recording; the first angle being different from the second angle. The detection device 2 comprises a first sensor 21 and a second sensor 22. The first sensor 21 detects the angular velocity and changes in direction of the toy 10, while the second sensor 22 detects the linear acceleration and changes in gravity of the toy 10.Specifically, the first sensor 21 is a gyroscope sensor and the second sensor 22 is an accelerometer. According to the above structure, when the gyroscope sensor and the accelerometer detect that the toy 10 has been turned upside down and rotated to the first angle and held for 3 seconds, for example, rotated 180 degrees and held for 3 seconds, the first audio recording is triggered, for example, "first voice change effect"; when they detect that the toy 10 has been turned upside down and rotated to the second angle and held for 3 seconds, for example, rotated 45 degrees and held for 3 seconds, the second audio recording is triggered, for example, "second voice change effect".
[0030] In another embodiment, the preset action involves pressing the toy 10. When the sensing device 2 detects that the toy 10 is being pressed with a first intensity, the control board 1 controls the speaker 4 to play the first audio recording. When the sensing device 2 detects that the toy 10 is being pressed with a second intensity, the control board 1 controls the speaker 4 to play the second audio recording; the first and second intensities differ from each other. The above structure allows the control board 1 of the toy 10 to play correspondingly different audio recordings when the sensing device detects that the toy 10 is being pressed with different intensities, for example, by light pinching or firm gripping.For example, a light pinch can trigger a "gurgling sound," while a firm grip can trigger an "expanding sound." Furthermore, the duration of the press can be set to differ from the playback time of the audio recording; for example, a 5-second press can trigger a 5-second audio recording.
[0031] In another embodiment, the toy 10 further includes an LED light and a vibration device, wherein, when the detection device 2 detects that the action of the toy corresponds to the preset action data 31, the control main board 1 controls the speaker 4 to play the audio data 32, and simultaneously controls the LED light to emit light and the vibration device to vibrate in order to achieve synchronized feedback by sound, light effects and vibration.
[0032] In another embodiment, the toy 10 includes audio data containing an announcement about the number of laps completed and an announcement about task failure / completion. The control board 1 triggers the announcement about the number of laps completed. When the detection device 2 detects that the toy has reached a certain number of laps completed, the toy 10 can issue an announcement about task completion. The above structure allows users to throw and spin the toy 10 in response to the announcement about the number of laps issued by the toy 10. Upon reaching the predetermined number of laps, the toy issues an announcement about task completion, thus extending the toy's play functionality.
[0033] In another embodiment, the preset action data includes 31 actions such as tapping, hitting, or rubbing. When the detection device 2 detects that the toy is being tapped, hit, or rubbed, the control board 1 directs the speaker 4 to play audio data. The audio data can be wind and rain sounds, cat or dog barking, or emotional expressions such as "You shake me, shake me, shake me until I get dizzy," imitating animals or characters.
[0034] In another embodiment, when the detection device 2 detects that the toy 10 is performing a preset action, the control board 1 controls the speaker 4 to output the first audio recording or the second audio recording in a specified sequence; for example, the control board 1 controls the speaker 4 to output the first audio recording after a first action has been performed on the toy 10; and the control board controls the speaker 4 to output the second audio recording after a second action has been performed on the toy 10; alternatively, the control board 1 controls the speaker 4 to output the first audio recording after a preset action with a first intensity has been performed on the toy 10;and the control mainboard 1 controls the speaker 4 to output the second audio recording after a preset action with a second intensity has been performed on the toy 10.;
[0035] In another embodiment, after it has been detected that the toy 10 is performing a preset action, the control board 1 can be triggered to control the speaker 4 to play the audio recording with a "humming" sound, and the audio recording ends with a "laugh." The above example can be used in passing games based on the principle of the "stop music game."
[0036] In another embodiment, when the detection device 2 detects that the toy 10 is thrown up and rotated by several angles such as a first angle, a second angle, the control mainboard 1 calculates and records the total rotation angle in real time, which is then converted into a score, and the final score is played back through the speaker.
