Description of the invention: ---- Technical Field of the Invention The present invention relates to a handheld device, and more particularly to a handheld device. [Prior Art] . Xunzi is a common entertainment tool, such as people like to shake the dice than the point size. Mobile phone manufacturers have introduced mobile phones with a dice function, which is used to tilt the phone to roll the dice, accompanied by the sound of dice rolling. Although the above mobile phone can simulate shaking the dice, the sound of the dice rolling is fixed, and the different sounds of the dice with different degrees of shaking cannot be reproduced. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a handheld device that can output a sound of tweezers rolling corresponding to the degree of shaking, and solves the problem that the existing handheld device cannot truly reproduce the sound of the dice rolling. To achieve the above object, the present invention provides a handheld device including a Φ processing unit, a memory, a motion sensing unit, and a decoding unit, wherein the motion sensing unit is configured to sense motion of the handheld device to obtain acceleration of the handheld device. The decoding unit is configured to decode the audio file stored in the memory, and convert the decoded digital signal into an analog signal for outputting, the memory storing a plurality of first type audio files and a comparison table. The first type of audio file is used to simulate the sound of shaking the dice with the tool, and the comparison table records the correspondence between the acceleration range of the handheld device and the first type of audio file, wherein the processing unit receives the motion sensing unit and transmits the real-time. The signal, according to the signal, determines the acceleration of the handheld device in real time, thereby 7 1343828 _ 竹年"月;日修(more) positive replacement page, according to the comparison table, determining the acceleration range in which the acceleration is located, 幷 in the acceleration range The first type of audio file corresponding to the acceleration range is played according to the comparison table for a continuous time. The handheld device of the present invention recognizes the motion acceleration by the sensing unit, outputs an audio file corresponding to the motion acceleration, and truly reproduces different sounds emitted by the dice depending on the degree of shaking. [Embodiment] _ Please refer to FIG. 1 , which is a hardware architecture diagram of the handheld device 10 of the present invention. The handheld device 10 includes a processing unit 11, a memory 12, a motion sensing unit 13, a random number generating unit 14, and a decoding unit 15. The motion sensing unit 13 is configured to sense the motion of the handheld device 10 to obtain the acceleration of the handheld device 10. In the embodiment, the motion sensing unit 13 can sense the X axis, the Y axis, and the Z axis. 3-axis acceleration sensor for acceleration. The memory 12 stores a plurality of shaking audio files and an ending audio φ file, and each of the shaking audio files and the ending audio files corresponds to a certain acceleration range of the handheld device 1 . The panning audio file is used to simulate the sound of the dice using the tool, which is used to simulate the sound of the dice relying on inertial scrolling after the shaking is stopped. In the present embodiment, the shaking audio file has four, that is, the first, second, third, and fourth shaking audio files, and the content thereof is the sound of shaking the dice with the wooden cymbal. Correspondingly, there are 4 end audio files, which are the first, second, third and fourth end audio files, respectively. The content is the sound of the dice relying on inertia to roll in the wooden raft after the shaking stops. The decoding unit 15 is used to decode the audio file stored in the memory 12, and convert the decoded digital signal into an analog signal output. . Please refer to FIG. 2, which is a comparison table for recording the correspondence between the acceleration range of the handheld device 1 and the shaking audio file and the ending audio file. The comparison ^ storage = memory 丨 2, the comparison table records the correspondence between the handheld device 1 , the degree 11 and the shaking sound (4) and the ending tone, such as when the acceleration of the handheld device 10 is at an acceleration When the range of the 2 zone is concerned, the corresponding corresponds to the second panning audio file and the second ending audio port. Among them, the acceleration 1 zone, the 2 zone, the 3 zone and the 4 zone are 4 consecutive numerical ranges, which are used to indicate the difference in severity of the handheld device 1G. It can be understood that the acceleration sensed by the motion sensing unit 13 is a linear acceleration sensor along the X-axis, the Y-sleeve, and the Z-axis direction. While the hand-held 10 is in actual motion, the direction of movement of the bowl is often not in any direction of the X-axis, the Y-axis or the 2-axis when the device 1G is shaken, and according to the vector decomposition, the acceleration is on the axis. The gamma axis and the two axes have components in both directions. That is, the processing unit u can determine the acceleration f of the handheld device 1G in the direction of the wheel, the 丫, and the 2 axes according to the motion sensing unit signal. Therefore, the acceleration of the handheld device 1G can be determined by adding the acceleration vectors on the three axes according to the principle of vector synthesis. Please refer to FIG. 3' for the acceleration graph of the shaking case_hand device 10. When the handheld device 10 is shaken, the motion sensing unit 13 signals a signal to the processing unit U, and the processing unit u determines, according to the signal, the acceleration of the page-receiving device ίο The size, so that the acceleration range in which the acceleration is located is determined according to the comparison table, and the shaking audio file corresponding to the acceleration range is played for a duration of the acceleration range. For example, in Fig. 3, the acceleration of the handheld device 10 after being shaken is gradually increased, and the acceleration magnitude is subjected to accelerations of 4, 3, 2, and 1 regions. At the beginning of the shaking, the acceleration of the handheld device 10 is in the acceleration zone 4, then the processing unit 11 controls the handheld device 10 to play the fourth shaking file 'the duration of the acceleration zone 4'. The handheld device 10 continues to play. The fourth shakes the audio file. In order for the handheld device 10 to more realistically simulate the sound of the shaking dice, an end audio file continues to be played after the shaking of the handheld device 10 is stopped. When the handheld device 10 is stopped, the acceleration of the handheld device 10 becomes zero, but the acceleration of the handheld device 10 during the shaking process cannot be excluded. Therefore, when the acceleration of the handheld device 10 becomes zero, the processing unit 11 controls the handheld device 10 to continue playing the rocking audio file played before the acceleration becomes zero for a predetermined time, such as continuing to play the corresponding shaking audio file. 0.5 seconds. If the acceleration is still zero after the predetermined time has elapsed, the processing unit 11 judges that the movement of the handheld device 10 is stopped. Then, the processing unit 11 plays the acceleration at a specific time before the zero time according to the acceleration, such as the acceleration at the first 0.2 seconds when the acceleration becomes zero, and plays the ending audio slot corresponding to the acceleration. After the end audio file is played, the processing unit 11 sends a signal to the random number generating unit 14, the random number generating unit generates one or more random numbers ranging between 1 and 6, and the processing unit 11 controls the Handheld j 343.828
