Description of the Invention: [Technical Field to Which the Invention Is Applicable] In particular, the present invention relates to a playable sound player having a detectable airflow intensity. [Prior Art] ° In recent years, many toys have music that has one or more tunes. For example, the device can be broadcast; in this kind of pipe music, one heart tunes. (4) The noise-retaining device adds play (four) funness to the system of the toy. ^, so that there is no straight-line audio player. The tune and volume played by this kind of audio player are also not controlled by the airflow intensity blown by the user. Therefore, the user cannot simulate the performance of the wind instrument. The wind instrument toy of the discharger cannot attract more consumers. The announcement date is June 13, 2001, the Chinese patent of 00250340, which discloses a toy sound control device. The utility model solves the problem that the user cannot simulate the performance of the wind instrument. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a longitudinal cross-sectional view of a Chinese patent of the application No. CN00250340, which is implemented in a toy. Fig. 2 is a schematic diagram showing the state of operation of the sounding control unit of the Chinese patent of Application No. CN00250340. The control unit 10 is placed at the position of the blowing nozzle 31 of the toy casing 30 (as shown in FIG. 1), and the air guiding port 1 of the control unit 10 and the blowing nozzle 31 are connected by an air guiding tube 32. When the blower 31 is blown toward the inside of the casing 30, the gas A can be introduced into the control unit 10 (shown in FIG. 1) via the air duct 32, and the pneumatic force is introduced into the control unit 10 to push the pneumatic The plate 13 is swung toward the spring piece 16 side (as shown in FIG. 2), and the pneumatic plate 13 can swing the shielding plate 14 between the light emitter 20 and the light receiver 21 around the pivot 15 while swinging toward the spring piece 16 side. The swinging causes the shield plate 14 to exit between the light emitter 20 and the wide receiver 21. The optical receiver 21 receives the light information generated by the light emitter 20 and outputs a control signal to a music chip (not shown) which emits music and sounds based on the control information. The utility model utilizes the swing of the pneumatic plate 13 to control the shielding plate 14 to cover the light receiving range of the light receiver 21 (as shown in Fig. 2). When the user's blowing strength is small, the amplitude of the swing of the pneumatic plate 13 is relatively small, the shielding plate 14 has a large shielding range, the light information received by the light receiver is weak, and the user's blowing strength is large, and the pneumatic plate 13 is swung. The amplitude is relatively large, the shielding panel 14 has a small shielding range, and the optical receiver receives relatively strong light information, thereby generating different control signals to the music chip to emit different music and sounds. However, the long-term use of the wind instrumental toy causes the elasticity of the spring piece 16 employed by the sounding control unit 10 to be weak, thereby affecting the sensitivity of the detection. In addition, the materials of the selected pneumatic plate 13, shield 14 and spring piece 16 may also affect the sensitivity of the detection. Based on the above problems, it is necessary to invent a playable audio player to simulate the performance of a wind instrument. SUMMARY OF THE INVENTION A playable audio player includes at least one button and a system for outputting a sound, and a power source for providing power for a playable audio player 8 1351678, a processor, a Memory and an audio playback unit. The memory stores a power level value and a volume control signal list, and the list defines a correspondence relationship between the plurality of power level values and the plurality of volume control signals. The player further includes a microphone, a signal amplifying unit, a sampling unit and an analog-to-digital converter. The player includes a normal working mode and a performance working mode. Press the button to put the player into the performance mode. In the performance mode, when the user blows through the air nozzle, the microphone is generated by the user's blowing intensity to generate a corresponding analog electrical signal, and the signal amplifying unit amplifies and inputs the analog electrical signal to the a sampling unit that samples the analog electrical signal and outputs an analog sampling signal to the analog digital converter. The analog digital converter converts the analog sampled quasi-signal to a digital sampled level. The processor receives the digital sampling level value, and queries the power level value, the volume control signal list, and outputs a volume control signal to the audio playing unit according to the query result. The audio playback unit controls the volume of the music output by the π eight according to the volume control signal. When the player does not detect airflow, the player stops outputting music. Pressing the button repeatedly causes the player to enter the normal working mode. In the normal working mode, the player normally plays the stored music. The tune of the user's favorite music can also be selected by operating the button. An advantage of the present invention is that the playable audio player can accurately detect the intensity of the user's insufflation, and control the volume of the music output by the speaker according to the detected insufflation intensity, thereby analogy to the wind of the pipe music crying.
