According to the present invention, an electronic playing device is provided, comprising a sound output circuit, a keyboard, a microphone circuit and a processor circuit. The keyboard generates the first blow information in response to the first blow operation event. The microphone circuit generates a second blowing information in response to the second blowing operation event. The processor circuit executes a blow mode' in response to the first and second blow information correspondingly generating a blow scale information. The processor circuit further provides a blow tone information to drive the sound output circuit to output a blow sound signal. According to the present invention, a music playing method is proposed, wherein "1, A is, 々A, and the towel is electrically played, and the music playing method includes the following steps. First drive the keyboard, ^ in response to the first - blow operation event to produce the first - blow information. Then drive the wind circuit, in response to the second blow, the secret is to create a second blow from the axe. Then, the blow mode is executed to generate the blow scale information in response to the first-A main operation. After that, the two beasts played a sound signal. After that, the following is a brief description of the following: In order to make the above-mentioned contents of the present invention more obvious and understandable, the preferred embodiment, together with the formula, is described in detail, such as [Embodiment], keyboard, and microphone playing operation. The event produces an electronic playing device including a sound output circuit circuit and a processor circuit. The keyboard is used to respond to the first 6 201021021 x w. The microphone circuit is responsive to the second blowing operation to generate the second blowing information. The processor circuit is configured to execute a blow mode to generate the blow scale information in response to the first and second blow information. The processor circuit further provides a blow scale information to drive the sound output circuit to output a blow sound signal. Referring to Figure 1, there is shown a block diagram of an electronic playing device in accordance with an embodiment of the present invention. The electronic playing device 1 includes a keyboard 12a, a microphone circuit 12b, a processor circuit 14, and a sound output circuit 16. The keyboard 12a generates the blow information Ini in response to the user-triggered blow operation event Evl. For example, the blow operation event Evl is, for example, an event in which the user presses a plurality of fixed keys on the keyboard 12a. The microphone circuit 12b is responsive to the user-triggered blow operation event Ev2 to generate the blow information In2. For example, the blow operation event Ev2 is, for example, an event in which the user blows the microphone circuit 12b, and the microphone circuit 12b senses the sound level of the user's blow motion to generate the blow information In1. The ® processor circuit 14 performs a blow mode in response to the blow information Ini and In2 correspondingly generating a blow scale information Ιο. For example, the processor circuit 14 determines the pitch range of the blow sound signal Αο according to the blow information Ιη2, and determines the exact pitch of the beat scale information 1〇 according to the blow information Ini. The processor circuit 14 further provides a blow tone information 1 drive sound output circuit 16 for outputting a blow sound signal Αο. The sound output circuit 16 is, for example, a thorn σ. In one example, the blowing mode performed by the processor circuit 14 corresponds to 201021021 1 w^iuyr/v is the mid-tone C trumpet playing mode. The microphone circuit 12b generates a corresponding blowing information In2 in response to the sounding action of the loud sound, to instruct the processor circuit 14 to select the mid-tone Si as the starting scale, and responds to the blowing action with a smaller sound. The information In2 is played to instruct the processor circuit 14 to select the scale midtone Fa as the starting scale. Three of the keys in the keyboard 12a, such as the number keys 1, the number keys 2, and the number keys 3, are designated to have a function of dropping two semitones, one semitone, and three semitones. By selectively pressing the numeric keypad ❹ keyboard 12a, a blowing information inini having six different values can be generated to instruct the processor circuit 14 to perform a drop, a decrease, a decrease, a decrease, and/or a corresponding initial scale. Drop 5 semitones. According to the above description, in response to the blow information W and in2, the processor circuit 14 can correspondingly determine the blow scale information 1 〇 having 12 pitches between the mid-tones Do and the middle sounds (middle D〇, mid-range buckle). Any of the pitches of the midrange Re, the midrange #Re, the midrange Mi and the midrange Fa, the middle (four), the middle sound, the middle sound depression #Sol, the middle sound La, the middle sound #La and the middle sound (1) The electronic playing device 1 further includes a memory Mc for storing a small sound file corresponding to 12 pitches between the mid-range Do and the middle-tone Si. The processor circuit responds to the blow scale rule, the processor circuit (4) The drive sound output circuit 16 subtracts the corresponding money sound charm to correspondingly output the blow sound signal Αο. In the actual _ towel, although only from the control circuit 14 responds to the keyboard coffee and the microphone material 12b provides the blow ftMni and - come The case where the aforementioned blowing operation is performed is taken as an example. However, the processor circuit 201021021 i yy jiKjyrn. 14 of the present embodiment is not limited thereto. In other examples, the electronic playing device i has other forms of users. Input interface device back to library '4, _ slave should correspond to The user operates to provide the corresponding blowing information. In the present embodiment, the case where the processor circuit is executed only by the c-tune-song type is described as an example. However, the processor circuit of the embodiment is not In other examples, the processor circuit i can perform other modes, and the processor circuit 1 has, for example, a mode selection interface, so that the user can switch between different modes through the mode selection interface. Referring to Fig. 2, another block diagram of an electronic plucking apparatus in accordance with an embodiment of the present invention is shown. For example, keyboard 22a provides control signal SC to processor in response to mode selection operation event Evs. The circuit 24 is executed by the control processor circuit 24 from a plurality of operating modes. For example, the mode selection operation event Evs is, for example, an operation event for inputting a corresponding instruction through the keyboard 22a in the operation menu of the electronic device 2 . In an example of operation, the processor circuit 24 performs a c-tune trumpet playing mode in response to the control signal SC, such that the electronic playing device 2 is executable as The operation performed by the sub-cinema device 1. In another example of operation, the processor circuit 24 performs a C-piano performance mode in response to the control apostrophe SC. In this example, several of the keys in the keyboard 22a are designated to have a corresponding The piano button function, in this way, the keyboard system provides a corresponding ensemble information Ιn3 to the processor circuit 24 in response to the user-triggered performance operation event Ev3. Thus, the processor circuit 24 can also correspondingly determine the performance scale information. 201021021
