New description: [New technology field] This creation is a racket, especially b, with a racquet about the sensing function of the right-handed Ι+· u.... Inside "Have a sweet spot [Previous technique] = Training the body's ability to reflect and be sensitive: The training of the athlete's muscle strength and endurance is also very helpful. The training for the exercise using the racket is the most difficult to perform because the athlete is hitting the ball with the racket, because the fast-moving of the ball is very: The process of mobilization cannot know whether the athlete can control the racket =/b hit the racket The sweet spot 'causes the athlete to be unable to adjust: position and posture. For example, taking the tennis player's training process as an example, the strength of the player's return stroke is not only in the strength of the player itself, but also has an absolute relationship with whether or not the player can hit the sweet spot of the racket. If the player is in the process of training. 'Unable to know the position of the hitting point has already fallen within the sweet spot area of the racket, it may cause the player to continue to hit the ball in the wrong position and posture during the game. 'The player must use more strength to fight back than the opponent'. Will lose the ball. [New content] In order to solve the aforementioned training process using the racket movement, it is impossible to confirm the position of the sweet spot of the 3 M384044 $, which may cause the player to continue to use the racket in the wrong posture or the return position. The sensing scheme gives the racquet the effect of sensing the sweet spot of the shot, so that when the player hits the ball, it can instantly know whether the hitting position is located in the sweet spot, and adjust the hitting position and posture. In order to solve the foregoing technical problems, the present invention provides a racket for the best hitting/= sensing function, comprising: a racket body and a judging module mounted on the racket body, the racket body comprising a racket portion and a fixed connection a hand-held portion of the racket portion; to the die-cutting module, and including a micro processing module, an analog digital signal converter, a three-axis acceleration sensor, a voice module, a speaker, an input interface, and a transmission interface, wherein: the output and the input end of the analog-to-digital signal converter are respectively electrically connected to the micro-module: and the three-axis acceleration sensor, and receive the three-axis acceleration: Measuring, 纟α fruit, converting the vibration sensing result into a vibration sensing digital signal and outputting to the micro processing module; the output input end of the /Hai voice module is respectively connected to the speaker and the micro processing=group' accepting The control of the microprocessor module drives the speaker to play an audio signal; the input interface is electrically connected to the microprocessor module, and is partially protruded from the handheld portion; the transmission interface and the micro processing a set of electrical connections; and an internal memory-spectrum database and a comparison program of the microprocessor module, the comparison program is based on the vibration sensing result of the three-wheeled acceleration sensor, and the contents of the spectrum database are compared to determine The racket body hits the drop position ' to control the voice module to cause the speaker to play the sound signal. 4 M384044 /, the middle 泫 辆 加速 加速 辆 辆 辆 辆 辆 辆 辆 辆 辆 辆 辆 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速 加速Guarantee, and let the '^ micro-processing group compare the spectrum database to determine the impact location. Day ★ Among them, the microprocessor module generates different sound signals depending on the impact position. In this way, the athlete can immediately understand the position of the hitting ball during the hitting process, so that the posture can be adjusted accordingly, and the problem that the training process towel cannot know the long-term misuse of the wrong posture caused by the hitting position can be solved, and the hitting position of the hitting ball can be achieved immediately. The technical effect of adjusting the posture in the training process. [Embodiment] Please refer to the first item and the figure: the embodiment of the racket which is the best hitting point sensing function of the present invention, which comprises a racket body (彳〇) and is mounted on the racket body (1)判断) a judgment module (20), the racquet body (1 〇) includes a racquet portion (11) and a hand-held portion (彳2) fixedly coupled to the racquet portion (1 ,), the racquet portion ( 11) Close to the center is a sweet spot (1彳J. When the user hits the ball with the racket body (10), if the hitting position is the sweet spot (111), the user only needs the least effort. The judgment module (20) comprises a micro processing module (22), an analog digital signal converter (23), a three-axis acceleration sensor (24), and a voice module ( 25), a speaker (26), an input interface (28) and a transmission interface (29).

The input interface (28) is electrically connected to the microprocessor module (22). a portion protruding from the handheld portion (12) for user operation (eg, opening, closing, setting, etc.) the determining module (2〇). • the transmission interface (29) and the micro processing module (22) An electrical connection, which can be any type of output connector for the connection and data transfer of the determination module (20) with an external device. - The micro-processing module (22) internally stores a spectrum database And a comparison program according to the sensing result of the three-axis acceleration sensor (24) and the content of the spectrum database, determining that the racket body is hitting the ball to control the voice module ( 25) Make the speaker (26) play a warning 响. Further, I. 旯 further explain that when the racket part (11) of the racket body (10) is subjected to “(4) impact, the impact position of the ball will cause the racket body (10) to vibrate (such as the vibrating towel*, frequency). ...etc.), in combination with this characteristic, the spectrum = the internal storage ball of the library meets the frequency of the different positions of the racket (11), and then, when the ball hits the racket (11) When the position is different, the micro-processing module (22) can recognize the position sensed by the three-axis acceleration sensor... The data is changed to the vibration state of the racket body (10), and then the spectrum is The library finds the corresponding data, and judges the position of the ball from the change and the difference of the frequency. η _, to control the speaker (26) to output different sounds, and let the motion D know whether the position of the ball is at the sweet spot ( 111). 6 M384044 The accuracy of the determination of the position of the hitting point is absolutely related to the content and accuracy of the spectrum database. Therefore, the following examples illustrate the way to establish the spectrum database.
