  The storage unit 22 is a storage unit such as a built-in or external nonvolatile memory, and includes a block information table (assigned sound information), a sound information table for each posture (sound information for each posture), and a posture determination table. An inter-block distance information table (sound control information) is stored. Here, FIG. 4A shows a configuration example and data example of the block information table. In the block information table 410, a block ID for identifying each block 10, and a color and a pitch assigned to the block 10 are associated with each other.

Also, the sound information table for each posture stores information on the sound assigned to each surface of each block 10. FIG. 4B shows a configuration example and a data example of the posture-specific sound information table corresponding to the block ID “100” as an example. In this example, the sound information table 420 for each posture is associated with sound and symbol information corresponding to the posture of the block 10 with the block ID “100”. The posture information indicates a surface that is an upper surface when the block 10 is placed on a horizontal surface, and information indicating a symbol drawn on the surface is associated with each surface.
In this example, when the surface 1 on which the pattern 420a is drawn is in an upper surface, a musical sound indicating a predetermined pitch is generated. Also, when the surface 2 on which the symbol 420b is drawn is an upper surface, a musical tone is generated by raising the pitch by a semitone, and when the surface 3 on which the symbol 420c is drawn is an upper surface, the pitch is increased. A tone with a semitone down is produced. When the surface 4 on which the pattern 420d is drawn is in the upper surface, a musical tone indicating the pitch value obtained by raising the pitch value of the surface 1 by one octave is generated. In the posture in which the surface 5 on which the pattern 420e is drawn is the upper surface, a musical tone is generated by further raising the pitch of the surface 2 by a semitone, and in the posture in which the surface 6 on which the pattern 420f is drawn is the upper surface, the pitch of the surface 3 A tone that is further lowered by a semitone is produced.

The positive and negative directions of the axis at which 1G gravitational acceleration is detected by the acceleration sensor 12 are associated with each other as the axial direction corresponding to the surface.

  Next, the inter-block distance information table will be described. FIG. 4D shows a configuration example and data example of the inter-block distance information table. The inter-block distance information table 440 stores an inter-block distance representing a positional relationship between the blocks 10 on the arrangement surface 200 and a sound length corresponding to the distance in association with each other. In this example, when the distance between the blocks 10 is not less than d1 and less than d2, the length of the sound of the sixteenth note is associated, and if it is not less than d2 and less than d3, the length of the sound of the eighth note is associated. The length of the sound is set to be longer as the distance between the blocks 10 is longer. In the present embodiment, the sound of each block 10 is generated in the order in which the blocks 10 are arranged. For example, when the block 10a is first arranged and then the block 10b is arranged, and the distance d between these blocks is not less than d2 and less than d3, the sound corresponding to the posture of the block 10a is the sound of an eighth note. The sound corresponding to the posture of the block 10b arranged last is pronounced with the length of the quarter note, which is the length of the reference sound. In the present embodiment, the sound length of the block 10 arranged last is configured to sound with the length of the sound of a quarter note, but for example, the block 10 to which no sound is assigned is previously stored. It may be configured so that the sound length can be adjusted according to the distance between the block 10 arranged in front of the block 10 and the block 10 by arranging the block 10 last.

Then, the generated musical tone signal is amplified by the voice output unit 27, and a musical tone based on the amplified musical tone signal is generated only once (step S24).
The sound and coordinate information specified for each block ID by the control unit 21 are sequentially stored in the order in which they are arranged in the RAM until the posture of the block 10 changes in association with the block ID, and the posture of the block 10 is changed. When changed, the sound and coordinate information associated with the block ID of the block 10 is deleted.

  Then, when the blocks 10 have been arranged in the desired order on the arrangement surface 200 of the main body device 20, the user presses the sound generation instruction button 20b. Thereby, the control part 21 acquires the operation signal which shows a sound generation instruction from the operation part 24, and judges that arrangement | positioning of the block 10 was completed (step S25: YES). The control unit 21 detects the distance between the blocks 10 in the arrangement order based on the coordinates of the block ID stored in the RAM, and specifies the length of the sound corresponding to the detected distance from the inter-block distance information table 440. . The control unit 21 generates a musical sound signal based on the sound information associated with the block ID and the specified sound length in the sound source unit 26, amplifies the musical sound signal in the audio output unit 27, and sequentially generates the sound (step) S26). By this process, musical sounds corresponding to the distance between the blocks 10 and the posture of the blocks 10 are generated in the order of the blocks 10 arranged by the user.

  In step S20, if the coordinates indicating the position of the block 10 are not output from the position detection unit 25 (step S20: NO), the control unit 21 determines that the block 10 is not arranged, and the main unit 20 Until the operation to switch off the power button 20a is performed (step 27: NO), the process of step S20 is performed, and when the operation to switch off the power button 20a is performed (step S27: YES), the process is terminated. . In step S25, the control unit 21 repeats the processing from step S20 onward until the sound generation instruction button 20b is pressed, that is, until the arrangement of the block 10 is completed (step S25: NO).

  The control unit 11 of the block 10 repeats the processing from step S11 onward until an operation for switching off the power switch is performed (step S14: NO), and when an operation for switching off the power switch is performed (step S14: YES), the process ends.

  In the above-described embodiment, musical sounds are generated according to the posture of the blocks arranged in the main body device 20 and the distance between the blocks. Therefore, music with different rhythms can be easily created by changing the position and posture of the blocks. be able to. Moreover, since the length of a sound can be changed according to the distance between blocks, the length of a sound can be adjusted intuitively.

  For example, in the case where the face 10 of the block 10 is placed on the staff score image 300 in a posture with the top face, a sound corresponding to a position on the staff (hereinafter referred to as an instruction sound) is generated with a quarter note length. The When placed in a posture with the surface 2 as the top surface, a sound is generated by raising the instruction sound by a semitone with the length of the quarter note, and when placed in a posture with the surface 3 as the top surface, A sound with a semitone lower than the instruction sound is produced. In addition, when the face 4 is arranged in a posture with the top face, the instruction sound is pronounced in the length of an eighth note, and when the face 5 is placed in a posture with the top face, the instruction sound is quartered with fortissimo. When a note is played with the length of a note, the sound is generated. When the face 6 is arranged in a posture with the top face, the sound when the instruction sound is played with the length of a quarter note by pianissimo is generated. In the present embodiment, based on the posture information table 630, the sounding mode of the instruction sound designated on the staff is changed according to the posture of the block 10. The posture information table 630 is used in common for all the blocks 10.

  In the sound information table 640, coordinates and sound on the staff score image 300 are defined, and sound information corresponding to the X coordinate, the Y coordinate, the X coordinate, and the Y coordinate indicating the coordinates at which the staff score image 300 is displayed is associated. It has been. In this case, the range of the X coordinate of the musical score image 300 corresponding to each sound is the same, and the range of the Y coordinate differs depending on each sound. For example, when the block 10 is arranged at a position where the X coordinate is in the range of X1 to Xn and the Y coordinate is greater than or equal to Y2 and less than Y3, the sound is identified.

(Operation)
Next, the operation of the tone generator 1 according to this embodiment will be described. The operation flow of the block 10 is the same as that of the first embodiment. When the communication distance between the control unit 11 of the block 10 and the main body device 20 is within the predetermined distance, the acceleration information detected every predetermined time by the posture information detection unit 12 and the posture information including the block ID That is, when the block 10 is arranged on the arrangement surface 200 of the main body device 20, it is connected to the main body device 20 and transmitted. Hereinafter, the operation of the main body device 20 in the present embodiment will be described.

  FIG. 12 is a diagram showing an operation flow of the musical tone sounding apparatus 1 in the present embodiment. When the power button 20a is pressed by the user (step S50: YES), the control unit 21 of the main device 20 displays a predetermined musical score image 300 on the display unit 28 at a predetermined position (step S51).

  The user sequentially arranges the blocks 10 at desired positions on the musical score image 300 displayed on the main device 20. The control unit 21 determines that the coordinates in the region of the staff score image 300 are sent from the position detection unit 25 and that the block 10 is arranged on the staff score image 300 (step S52: YES). The control unit 21 receives attitude information from the block 10 when the block 10 is arranged, detects the color and attitude of the arranged block 10, and arranges coordinates where the detected color, attitude, and position are associated with each other. Information is stored in the RAM for each block 10 (step S53).

  That is, the control unit 21 extracts a block ID from the posture information received from the block 10 and specifies a color corresponding to the block ID from the block information table 620. Then, acceleration information is extracted from the posture information, the axial direction in which the 1G gravitational acceleration is detected is specified, and the posture corresponding to the specified axial direction is specified based on the posture determination table 430 in the storage unit 22. . And the control part 21 memorize | stores the arrangement | positioning coordinate information which matched the color and attitude | position identified about the arrange | positioned block 10 with the coordinate detected in the position detection part 25 in RAM. Whenever the arrangement coordinate information is stored in the RAM, the control unit 21 generates a tone signal corresponding to the arrangement coordinate information based on the tone color information table 610, the block information table 620, the posture information table 630, and the sound information table 640. The musical tone signal generated by the unit 26 is amplified by the voice output unit 27 and is generated only once (step S54).

  When the user finishes arranging the block 10, the user presses the sound generation instruction button 20b. By this operation, an operation signal indicating a sound generation instruction is sent from the operation unit 24 to the control unit 21, and the control unit 21 determines that the arrangement of the block 10 is completed (step S55: YES). And the control part 21 reads each arrangement | positioning coordinate information memorize | stored in RAM, and specifies the combination of the color of the block 10 arrange | positioned from the color information in each arrangement | positioning coordinate information. Further, the timbre corresponding to the identified combination of colors is identified from the timbre information table 610 in the storage unit 22.

  The control unit 21 specifies the sound corresponding to the Y coordinate of each arrangement coordinate information from the sound information table 640 in the storage unit 22 in ascending order of the X coordinate value in each arrangement coordinate information, The sound generation mode corresponding to the posture of the block 10 is specified from the posture information table 630 in the storage unit 22. Then, the control unit 21 generates a musical tone signal based on the specified tone color, sound, and sound generation mode in the sound source unit 26, and amplifies the generated musical tone signal in the voice output unit 27 to generate a sound (step S56). Thereby, a sound corresponding to the position, posture, and color of the block 10 arranged on the staff score image 300 is generated.

<Modification>
Although the embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments, and can be implemented in various other forms. For example, the above-described embodiment may be modified as follows to implement the present invention, or may be implemented in combination with each modification. Hereinafter, modifications of the embodiment according to the present invention will be described.

(1) In the first and second embodiments described above, the block 10 is arranged on the arrangement surface 200 of the main body device 20, but another block 10 is stacked on the block 10 arranged on the arrangement surface 200. It may be. In this case, close proximity wireless communication is performed between the blocks 10. For example, when the block 10b is stacked on the block 10a arranged on the arrangement surface 200, it is assumed that the distance between the block 10b and the main body device 20 is a distance where close proximity wireless communication is not possible. At this time, posture information including the block ID and acceleration of each block is transmitted and received between the block 10a and the block 10b, and the block 10a transmits the posture information of the block 10b to the main body device 20. The main body device 20 associates the posture information of the block 10b received from the block 10a with the block ID of the block 10a together with the information indicating that it is the posture information of the block 10b arranged in the second stage of the block 10a. To remember. Thereby, even if it is a case where the block 10 is arrange | positioned three-dimensionally, in the main body apparatus 20, the positional relationship between the blocks 10 can be specified. In addition, the sound control information (sound length, tone color, etc.) for changing the sound of each block 10 according to the positional relationship of the three-dimensional block 10 is configured in advance so as to be arranged in the main body device 20. Sounds corresponding to the three-dimensional arrangement can be generated according to the sound control information.
In the above configuration, when another block 10c is arranged on the arrangement surface 200 so as to be close to the block 10a, close proximity wireless communication is performed between the block 10a and the block 10c, and the block ID of each block is the block ID. Each posture information is transmitted to the main body device 20. In this case, the position detection unit 25 of the main body device 20 detects the positions of the blocks 10 a and 10 c, and the posture information of each block is also transmitted to the main body device 20. After receiving the posture information of the block 10a from the block 10a, the main body device 20 receives the posture information including the block ID of the block 10c from the block 10a. Further, after receiving the posture information of the block 10c from the block 10c, the main body device 20 receives the posture information including the block ID of the block 10a from the block 10c. Therefore, in this case, the main body device 20 receives the posture information of the block 10a and the block 10c not only from the block but also from other blocks.
Thus, when the main body device 20 receives a plurality of posture information for one block 10, if the one block 10 is a block detected by the position detection unit 25, the main device 20 starts from the one block 10. By configuring the main body device 20 to store the transmitted posture information, the posture information for one block 10 can be uniquely specified.

Although the example to perform was used, the aspect which produces a sound according to the positional relationship of the block 10 is not restricted to this. For example, the sound of each block 10 may be generated according to the opposing surfaces of the blocks 10 in the arrangement order. For example, the top surface, the bottom surface, the right side surface, the left side surface, the front surface, and the back surface of each block 10 when the positive direction of the Y axis of the arrangement surface 200 is the front surface are specified, and according to the combination of the facing surfaces of the block 10, A sound is generated by changing the sound generation mode of the block 10.
It should be noted that the sound generation of the block 10 may be controlled according to the face or distance facing the other block 10 arranged within a certain distance range from the arranged block 10 regardless of the arrangement order. In this case, when the plurality of blocks 10 are each within a certain distance range, the sound may be generated in a sound generation manner corresponding to the surface or distance facing the block 10 having the maximum or minimum distance between the blocks 10. Moreover, you may make it sound in the sounding aspect according to the distance with the block 10 with which the opposing surface corresponds among several blocks 10, and the combination of the said opposing surface.
