DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an external perspective view of a music box 10 according to an embodiment of the present invention. The main body case 1 is made of wood and has an opening at the top. A lid 11 having an L-shaped cross section is attached to one side of the opening by a hinge 12, and the lid 11 can be opened and closed. A liquid crystal display 11a is disposed on the back side of the lid 11, and this liquid crystal display 11a can be used for displaying a musical score of music to be reproduced. A comb 2 is attached in the main body case 1 by a frame 13, and an electronic device part A is disposed on one side of the comb 2. The comb 2 is shaped into a comb shape by making a large number of cuts in a metal plate, and has a large number of vibration valves 21 corresponding to the comb teeth.
[0018]
An actuator array 3 is disposed below the vibration valve 21 of the comb 2, and the actuator array 3 includes a plurality of actuators 31 corresponding to the vibration valves 21 of the comb 2. The actuator 31 is driven by the control of an electronic circuit (described later) of the electronic device unit A, and is configured to flip the corresponding vibration valve 21 from below. The vibration valves 21 are formed so that the thickness gradually becomes thinner from the left side to the right side of FIG. 1. When the vibration valves 21 are repelled, the vibration valves 21 are sequentially semitones from the left end vibration valve 21 to the right end vibration valve 21. It is set so that the pitch becomes higher. Then, the vibration valve 21 struck by the accumulator 31 vibrates, and the vibration is transmitted to the main body case 1 through the frame 13, and the main body case 1 resonates and produces sound.
[0019]
A disc-shaped rotating disk 4 is rotatably disposed beside the comb 2 in the main body case 1, and a crank-shaped handle 5 drawn out of the main body case 1 is provided at the center of the rotating disk 4. It is attached. Further, a magnetic sensor 6 is disposed in the vicinity of the outer periphery of the rotating disk 4, and when the rotating disk 4 is rotated by the handle 5, a pulse signal corresponding to the rotation direction and rotation speed of the rotating disk 4 is output from the magnetic sensor 6. Is output.
[0020]
An accumulated mark length setting switch s, which will be described later, is disposed below the handle 5 on the side surface of the main body case 1. A slot hole 14 for inserting a Memory Stick (registered trademark) B for supplying music data from the outside is formed on the front surface of the main body case 1, and a preparation switch a and a music selection switch g, which will be described later, are provided. ing. Further, a USB terminal A1 connected to a personal computer or the like to be described later is attached to the electronic device part A side of the main body case 1. This terminal may be of IEEE 1394 standard or others.
[0021]
FIG. 2 is a diagram showing details of the rotating disk 4 and the magnetic sensor 6. As shown in FIG. 2 (A), a rubber-like magnet 41 is attached around the rotating disk 4. The rubber-like magnet 41 has a magnetic pattern in which N poles and S poles are alternately arranged in the circumferential direction. Two rows are formed. The striped pattern shown in the figure shows the boundary between the magnetic poles in an easy-to-understand manner and is not actually visible. Further, as shown in an enlarged view of the magnetic pattern in FIG. 2 (B), the two magnetic patterns are arranged so that the same pole is shifted by half the length. As shown in FIG. 2A, the magnetic sensor 6 includes two Hall elements 6a and 6b, and these two Hall elements 6a and 6b are provided side by side in a direction perpendicular to the longitudinal direction of the magnetic pattern.
[0022]
With the above configuration, when the rotating disk 4 is rotated by turning the handle 5, pulse signals due to changes in the magnetic poles of the rubber-like magnet 41 are output from the Hall elements 6a and 6b. FIG. 3 is a diagram showing this pulse signal. When the turntable 4 is rotated clockwise, for example, when viewed from the handle 5 side (this is assumed to be forward rotation), the hall element 6a is turned on as shown in FIG. A pulse signal φA is output, and a pulse signal φB having a phase delayed by ¼ from φA is output from the Hall element 6b. Further, when rotating counterclockwise (this is referred to as reverse rotation), the pulse signal φA is output from the Hall element 6a as shown in FIG. 3B, and the phase is ¼ from φA from the Hall element 6b. The advanced pulse signal φB is output. Then, a count value corresponding to the rotation angle of the turntable 4 is obtained from the pulse signal φA. In the second embodiment, which will be described later, the rotation direction of the turntable 4 is detected by the phase shift between the pulse signals φA and φB.
[0023]
The structure of the music box 10 described above is common to the following embodiments.
[0024]
(First embodiment)
FIG. 4 is a block diagram of the electric circuit of the first embodiment. The music data external memory B is the memory stick B or the like that stores music data in the SMF (standard MIDI file) format, and the music data is converted from the music data external memory B to the format conversion unit by operating the preparation switch a. Read by b. The format conversion unit b converts the MIDI format into a predetermined format handled by the music box main body, and sequentially writes the converted data in the internal memory c. The format conversion unit b outputs an end signal every time conversion of music data for one song is completed, and this end signal is output to the song number information search & detection unit d.
[0025]
The song number information search & detection unit d searches and detects the start address and song number information of the song data currently converted in the internal memory c in response to the input of the end signal from the format conversion unit b. Is written in the area corresponding to the song number in the song start address designating part e. By repeating this, the music data of a plurality of songs are converted into a predetermined format and written in a predetermined area of the internal memory c, and the head address of each music data corresponds to the music head address designation section e corresponding to the music number. To be recorded. When the song number information search & detection unit d detects the head address, it outputs an enable signal to the step counter f, thereby enabling the operation of the step counter f.
[0026]
FIG. 5 is a diagram showing the recorded contents of the internal memory c. A plurality (1 to n songs) of song data is recorded in the internal memory c, and the start address of all songs and the information of the song numbers are recorded in the song number information area. The music data of one song stores a plurality of sets of data corresponding to the number of notes for one song, with each piece of pitch, touch and sounding timing data corresponding to one note as one set. Here, the music data in the music box is converted so that the sound generation timing is slightly shifted for a plurality of notes that are simultaneously sounded in the original music data, or substantially the same sound generation timing data is converted into different set data. It can be pronounced by prescribing. The music data for one song is recorded sequentially in the order of the notes from the beginning address (P0) of the song. A data set of pitch, touch and sounding timing corresponding to one note is referred to as “note data”.
[0027]
The pronunciation timing data is based on a clock with a predetermined resolution corresponding to, for example, 24 clocks per quarter note (96 clocks per bar with 4/4 time signature), and the number of clocks from the beginning of the song to that note. It is remembered. However, as indicated by the arrows in the figure, the pitch data and touch data are set with the sound generation timing data of the previous address. The pitch data and touch data at the head address (PO) are dummy data. The pitch data is, for example, data not used for a note code, and the touch data is “0”. The sound generation timing data at the last address is also dummy data, for example “0”. The reason for this configuration is to pre-read the sound generation timing data of the next note at the time of sounding one note.
[0028]
In FIG. 4, the music selection switch g is a plurality of switches corresponding to the music numbers, and when a switch corresponding to the music number is operated, a reset signal is output via the OR circuit h. A first counter i1 and a second counter i2, which will be described later, are reset. Further, by operating the music selection switch g, the music start address corresponding to the operated switch is selected by the music start address designating section e and output to the step counter f. The step counter f is reset at a timing before the start address is output.
[0029]
The step counter f serves as an address counter for the internal memory c, and updates the count value (address) every time a coincidence detection signal from the coincidence detection unit j described later is input to the clock terminal. Then, the internal memory c is accessed by the address output from the step counter f, and data for each note of the music data is output.
[0030]
The note data (pitch data, touch data, sounding timing data) output from the internal memory c is output to the pitch detection unit k, the touch detection unit m, and the timing detection unit n, and the pitch detection unit k is derived from the note data. The pitch data is detected and output to the line signal converter p. Here, each vibration valve 21 of the comb 2 has an individual pitch, and each actuator 31 of the actuator array 3 corresponds to each vibration valve 21. That is, each actuator 31 corresponds to a pitch. On the other hand, the line signal conversion unit p has a multi-bit output line p1 composed of bits respectively corresponding to the actuators 31 of the actuator array 3, and the pitch data input from the pitch detection unit k Only the bit of the actuator 31 corresponding to the pitch is converted into a line signal with “1” and other bits being “0” and output to the drive circuit q. The touch detection unit m detects touch data from the note data and outputs it to the D / A conversion unit r. The D / A conversion unit r converts the touch data into an analog signal and outputs the analog signal to the drive circuit q.
[0031]
FIG. 6 is a circuit diagram showing details of the drive circuit q. The drive circuit q is composed of each analog gate q1 connected between each drive coil 31a of each actuator 31 and the output line of the D / A converter r. It is configured. Each bit line of the output line p1 of the line signal conversion unit p is connected to the gate terminal of each analog gate q1. From the D / A converter r, for example, an analog signal of a level corresponding to the touch data as shown in the figure is output, and a current is supplied to the corresponding drive coil 31a via the analog gate q1 in which the bit of the output line p1 is set. The supplied actuator 31 is driven.
[0032]
FIG. 7 is a diagram illustrating a main configuration of the actuator 31. The actuator 31 has a plunger 31b made of a rod-like permanent magnet in the drive coil 31a, and the lower end of the plunger 31b is pulled by a tension spring 31c. When the drive coil 31a is not energized, the plunger 31b is in the position shown in FIG. 7A. When the drive coil 31a is energized, the magnetic force of the plunger 31b and the magnetomotive force of the drive coil 31a repel each other. 7 (B), the plunger 31b protrudes upward and strikes the vibration valve 21. As a result, the vibration valve 21 vibrates and produces sound. Even if the plunger 31b strikes the vibration valve 21 even during energization, the plunger 31b at the striking position slightly returns due to the tension spring 31c and gravity because the drive current is attenuated. Thereafter, the state returns to the state shown in FIG.
[0033]
With the above configuration, when the note data is output from the internal memory c, the vibration valve 21 corresponding to the pitch data generates a sound with a predetermined pitch and generates a sound with a volume corresponding to the touch data. The timing of sound generation is controlled by a timing detection unit n, a first counter i1, a second counter i2, a coincidence detection unit j, and a pulse signal φA output by the rotation of the turntable 4, which will be described next.
[0034]
In FIG. 4, an integrated mark length setting switch s, which is a changeover switch, is connected between a first counter i1 and a second counter i2. The first counter i1 is a 3-bit counter that counts the rising edge of the pulse signal φA input to the clock terminal (CK). The first bit (the least significant bit), the second bit, and the third bit (the most significant bit) ) Is output to the second contact point s2, the third contact point s3, and the fourth contact point s4 of the integration mark length setting switch s. In addition, a pulse signal φA is output to the first contact s1 of the integrated mark length setting switch s. Further, the common contact point s5 of the integration mark length setting switch s is input to the clock terminal (CK) of the second counter i2. The second counter i2 is a 16-bit counter, for example, and counts the rise of the pulse signal φA input to the clock terminal. The count value of the second counter i2 is output to the coincidence detection unit j.
[0035]
On the other hand, when the note data is output from the internal memory c, the timing detector n detects the sounding timing data from the note data and outputs it to the coincidence detector j. When the count value output from the second counter i2 matches the value of the timing data output from the timing detector n, the match detector j outputs a match signal to the step counter f. Then, the access address of the internal memory c is updated by this coincidence signal, and the next note data is output.
[0036]
That is, the sound generation timing data of the note to be generated is pre-read by the timing detection unit n, and the pulse signal φA output in response to the rotation of the turntable 4 is used as a clock corresponding to the performance flow by the second counter i2. When the count value coincides with the sound generation timing data, the pitch data and touch data to be set together with the sound generation timing data are read out from the next address to generate sound. Therefore, as the rotating disk 4 is rotated, note data is sequentially output from the internal memory c, and the performance proceeds.
[0037]
Here, the integrated mark length setting switch s selectively connects the common contact s5 to the first to fourth contacts s1 to s4, and the rising of the output of the selected contact is counted by the second counter i2. Is done. On the other hand, when the first counter i1 counts the pulse signal φA, the first bit of the first counter i1 includes “1” every two pulses as in the case where the pulse count is “1, 3, 5,. "Stands. In the second bit, “1” is set every four pulses as in the case where the pulse count is “2, 6, 10,...”. Further, in the third bit, “1” is set every 8 pulses as in the case where the pulse count is “4, 12, 20,.
[0038]
Accordingly, when the first contact point s1 is selected in the integrated mark length setting switch s, the second counter i2 counts the pulse signal φA as it is, and when the second contact point s2 is selected, the second counter i2 is the pulse signal. Every other φA is counted, and when the third contact s3 is selected, the second counter i2 counts every third pulse signal φA. Further, when the fourth contact s4 is selected, the second counter i2 counts every seven pulse signals φA. When this is considered with respect to the frequency of the pulse signal φA, the above-described operation by the first counter i1 and the second counter i2 is performed by changing the pulse signal φA to 1/1, 1/2, 1 according to the setting of the integration mark length setting switch s. This corresponds to dividing into / 4 and 1/8.
[0039]
Thereby, the resolution of the rotation angle of the turntable 4 with respect to the note length can be set according to the setting of the integrated note length setting switch s. FIG. 8 is a diagram conceptually explaining the relationship between the note length and the resolution of the rotation angle. It is 24 clocks per quarter note (96 clocks per bar in 4/4 time), and per turn of the rotating disk 4. A case where the pulse signal φA is 192 pulses will be described.
[0040]
When the accumulated contact length setting switch s is set to the first contact s1 (FIG. 8A), the count value of the second counter i2 corresponding to one rotation is 192, and 192/24 = 8 makes 1/8 rotation. Corresponds to one quarter note (2 bars per rotation). When the second contact point s2 is set (FIG. 8B), the count value of the second counter i2 corresponding to one rotation is 96 (= 192/2), and 96/24 = 4 is 1/4 rotation. Corresponds to one quarter note (a full note or one measure per rotation). When the third contact point s3 is set (FIG. 8C), the count value of the second counter i2 corresponding to one rotation is 48 (= 192/4), and 48/24 = 2 is 1/2. The rotation corresponds to one quarter note (one rotation is a half note). When the fourth contact s4 is set (FIG. 8 (D)), the count value of the second counter i2 corresponding to one rotation is 24 (= 192/8), and one rotation is made when 24/24 = 1. Corresponds to one quarter note.
[0041]
As described above, if the turntable 4 is rotated fast, the performance progresses fast, and if it is rotated slowly, the performance progresses slowly. However, when the rotation speed is constant by setting the integrated note length setting switch s as described above. The performance speed can be increased or decreased so that various performances can be performed. Further, since the reproduction is performed following the hand turning operation of the handle 5 (rotation of the turntable 4), a mechanic feeling or a manual feeling can be enjoyed like a conventional music box.
[0042]
(Second Embodiment)

The direction detection unit t detects the rotation direction of the turntable 4 from the phase shift of the pulse signals φA and φB, and the count-up / count-down function in the first counter i1 ′ and the second counter i2 ′ is selected by the direction detection signal. Is done. A technique for detecting the rotation direction from the phase shift between the pulse signals φA and φB as described above is disclosed in, for example, Japanese Patent No. 2626133. The format converter b ′ converts the supplied music data into the format of the second embodiment and stores it in the internal memory c ′. A plurality of pieces of music data are stored in the internal memory c ′ as in the first embodiment, but each piece of music data for one music is generated from the start address (P0) of the storage area as shown in FIG. The note data of the sounding timing is stored at the address position corresponding to ().
[0044]
That is, in the second embodiment, the note data is pitch data and touch data, and the tone generation timing corresponds to the relative address from the start address of the storage area of one song. That is, the count value (clock) of the second counter i2 'and the relative address from the head address are in a linear relationship, and the address conversion unit f' converts the increase / decrease of the count value of the second counter i2 'into the increase / decrease of the address. To do. Then, the internal memory c ′ is accessed by the output of the address conversion unit f ′, and the note data is output. The note data is output to the pitch detection unit k and the touch detection unit m.
[0045]
With the above configuration, in the second embodiment, when the turntable 4 is rotated forward, the count value of the second counter i2 'increases and the access address of the internal memory c' increases, so that the music is reproduced in the forward direction. The On the other hand, when the turntable 4 is rotated in the reverse direction, the count value of the second counter i2 ′ decreases and the access address of the internal memory c ′ decreases, so that the music is reproduced in the reverse direction. The resolution of the rotation angle of the turntable 4 with respect to the note length can be set by the setting of the integrated note length setting switch s as in the first embodiment.

With the above configuration, when the vibration valve 21 is not struck, as shown in FIG. 10A, the plunger 32b is pushed into the cylinder 32a and the control plate 32e is in contact with the upper end of the inclined surface 32b-1. Is in a state. Then, as shown in FIG. 10B, when the solenoid 32d is driven to move the control plate 32e away from the inclined surface 32b-1, the plunger 32b is projected by the compression spring 32c, and the vibration valve 21 is hit. When the plunger 32 b hits the vibration valve 21, it immediately falls into the serial 32 a as shown in FIG. 10C and does not interfere with the vibration of the vibration valve 21. In this state, when the solenoid 32d is driven to cause the control plate 32e to protrude, the tip of the control plate 32e presses the inclined surface 32b-1 downward, so that the plunger 32b returns to the state shown in FIG.
[0051]
The inclined surface 32b-1 may be a flat surface, but the following effects can be obtained if the inclined surface 32b-1 has a circular arc shape as described above. When the inclined surface 32b-1 is pressed by the control plate 32e, the repulsive force of the compression spring 32c increases as the plunger 32b sinks downward, but the inclined surface 32b-1 has an arcuate shape, so that the plunger 32b As it sinks downward, the angle between the control plate 32e and the inclined surface 32b-1 (tangent plane) at the contact portion between the control plate 32e and the inclined surface 32b-1 becomes smaller, and the downward component of the pressing force is correspondingly reduced. Since it becomes large, the plunger 32b can be easily sunk.

In step S12, the personal computer 20 displays a download screen for music data desired by the user and a purchase button on the display 20f based on the received HTML file. Next, in step S13, if the user clicks the purchase button, information indicating that the purchase is made is transmitted, and if the user clicks the preview button, information indicating that the preview is transmitted is transmitted. The server 50 monitors whether or not the information for trial listening is received in step S23, and whether or not the information for purchase is received in step S24. If the information indicating the trial listening is received, the trial listening data of the music data desired by the user is read from the storage device 50a and transmitted in step S25. When the information to purchase is received, in step S26, an HTML file including a screen for selecting a payment method and inputting necessary items is transmitted, and the process proceeds to step S27.
[0061]
In the personal computer 20, it is determined whether or not the information for trial listening is transmitted in step S14, and if the information for trial listening is not transmitted, the process proceeds to step S16 and the information for trial listening is transmitted. In step S15, the pseudo music box trial listening process (subroutine; see FIG. 16) shown in FIG. 16 is performed. Then, when the trial listening is completed in the pseudo music box trial experience processing as described later, in step S16, a screen (sales purchase execution screen) for selecting purchase of music (desired to distribute music data) or purchase of music box is displayed. Then, the input selection process is performed on the sales / purchase execution screen to determine whether or not purchase is selected. If purchase is not selected, the process proceeds to step S101. If purchase is selected, the process proceeds to step S17. In step S17, it is determined whether information indicating purchase is transmitted. If information indicating purchase is not transmitted, the process proceeds to step S101.
[0062]
If information indicating purchase is transmitted in step S17, an HTML file related to payment is received in step S18, a screen corresponding to the HTML file is displayed, and a process for selecting a payment method is performed by the user. A process is performed in which the user inputs items necessary for payment, and the input information is transmitted. In step S27, the server 50 monitors whether the payment method and necessary information are received. If received, in step S28, if the purchase target is a song, the desired song data is transmitted. The process ends.
[0063]
In the personal computer 20, the desired music data transmitted in step S19 is received and stored in the storage device 20b, and the process proceeds to step S102. Step S101 is processing when the currently selected music data is not purchased, and it is determined whether or not the user has selected another music. If another song is not selected, the process proceeds to step S102. If another song is selected, the processes in and after step S12 are repeated. In step S102, it is determined whether or not there is a termination instruction from the user.
[0064]
In the pseudo music box trial-listening experience processing of FIG. 16, first, when the trial-listening data is received in step S31, the trial-sound data is converted into a predetermined format handled by the music box 10, that is, music data for music box while being stored in the internal memory (storage device 20b etc.). In step S32, it is monitored whether the data format conversion is completed. When the data format conversion is completed, in step S33, a process of assigning the start address in the memory to the song data corresponding to the song selection switch displayed on the display screen of the display 20f (the start address process in the song selection SW memory) is performed. The music is displayed in correspondence with the music selection switch on the display screen.
[0065]
In step S34, it is monitored whether any of the song selection switches is turned on (left click of the mouse 20h, etc.). If turned on, in step S35, a preset song progression address memory step counter is set. The accumulated speed of a counter (accumulated mark length) that determines the stepping cycle is preset in correspondence with the music, and in step S36, one cycle of the rotation operation of the USB1 controller (mouse 20h, etc.) corresponds to the above stepping cycle.

Next, in step S37, one selected start address of a plurality of music pieces is designated, and the first note length data is set in a preset F register, and the process proceeds to step S38. In step S38, it is determined whether or not the controller (mouse 20h) is rotating. If there is no rotating operation, the process proceeds to step S305. If there is a rotating operation, the rotation angle of the controller (mouse 20h) is detected in step S39. The rotation angle can be detected (calculated) as appropriate based on, for example, the locus of the cursor of the mouse 20h and the coordinate data. Next, in step S301, screen processing for displaying (updating) a moving image in which a music box cylinder or handle rotates is performed, and the process proceeds to step S302. In step S302, it is determined whether the current rotation angle of the controller (mouse 20h) has reached the read mark length value (timing) of the F register. If not, the process proceeds to step S38, and if it has reached, the process proceeds to step S303.
[0067]
In step S303, pitch data having a timing that coincides with the read mark length value (timing) of the F register is sent to the sound source circuit 20i (sound source). In step S304, the read counter is incremented, and the next for comparison purposes is incremented. Is placed (updated) in the F register, and the process returns to step S38.
[0068]
In step S301, the music box displayed is a music box sold on the net, and has been subjected to image processing so that the cylinder, the handle, and the comb are driven in conjunction with the movement of the mouse 20h.
[0069]
If the controller (mouse 20h) continues the rotation operation by the processes in steps S38 to S304, an image showing the music box moving is displayed on the display 20f, and the music is reproduced following the rotation operation. Advances. At this time, if the rotational operation is speeded up, it is played back faster, and if it is slowed down, it is played back later. When the rotation operation of the mouse 20h is stopped, the process proceeds from step S38 to step S305.
[0070]
In step S305, while stopping the rotation of the music box cylinder and the handle on the display screen, a screen process is performed to prompt the user to input whether or not to end the audition, and the process proceeds to step S306. In step S306, it is determined whether or not an instruction to end the trial listening has been given (OK). If the trial listening has not ended, a selection screen for another song is displayed in step S307 and the return switch is turned on (right of the mouse 20h). Click). If the return switch is not turned on (if the mouse rotation is resumed, the process returns to step S38, and if the return switch is turned on, the process returns to step S32. If the audition is completed in step S306, the process returns to the original routine. That is, the process proceeds to step S16.
[0071]
