Description

Description: TECHNICAL FIELD The present invention relates to a sound generator, and more particularly to a sound generator that emits a sound and displays it when a reserved time is reached.

[Prior Art] It is generally known that, when an operator sets a time in advance, an alarm is displayed with a sound at the time. Further, such display contents also tend to be advanced from a simple bell sound to a sequence of words having meaning contents generated in correspondence with the contents to be displayed.

[Problems to be Solved by the Invention] By the way, since the conventional timer device has been mainly focused on accurately displaying the reserved time, its use is rather limited except during the timer processing at each set time. Therefore, it is the current situation that the sound generating means, which has been highly advanced recently and has been adopted for the timer device, has not been effectively utilized.

[Means for Solving Problems] The present invention has been made in view of the above-mentioned problems, and a plurality of types of words, melody, etc. are interlocked with a switch operation except when it is used as a timer device. It is intended to provide a sound generation device which can be used also as a game device utilizing randomness of a combination of words by randomly generating the sound.

FIG. 1 illustrates the configuration of the present invention, in which the reservation time set by the reservation setting means and the reference time are input to the coincidence determining means, and when the both times coincide, the display means is operated to make a sound. The sound generating device is provided with a sound processing means capable of accessing the display means in association with a switch operation, and at every time the switch is operated, a word or a melody which the display means has in advance for reserved display is randomly generated. During the reservation process, the sound generation from the display means can be forcibly stopped.

[Operation] In the above configuration, when the operator operates the switch, one set of words or a melody is issued every time the switch is turned on. A plurality of such sounds are prepared, and the output order is preset so that the output order is as irregular as possible. Any combination of words and melodies can be arbitrarily tried, and the otherness of the combination is displayed to the operator.

On the other hand, during the alarm processing which works as the timer device, the sound is forcibly stopped by the switch operation contrary to the above.

FIG. 4 is a block diagram showing an outline of an electric circuit used in the timer unit 2, in which a central processing unit (CPU) which operates by a program is used as the center of control, the central processing unit 50 and the RAM 51, ROM5
The control unit 56 is configured by connecting the storage device 53 and the input / output device 54 such as two via various buses 55. Further, the input / output device 54 includes a voice generator 57, a display unit 60 including a melody generator 58, or a controller 5.
By connecting the switch unit 61 that allows the operator to directly access the unit 6, various timer operations such as various reservation settings or sound generation by the display unit 60 at the reserved time are enabled.

FIG. 5 shows an example of a more specific electric circuit. A microprocessor (for example, μPD7507SC) in which a 4-bit CPU 50 that operates as a central processing unit, a RAM 51 that functions as a work area, a ROM 52 that stores an execution program in advance, and an input / output device 54 that exchanges data with an external circuit are integrated in one chip Used as the control unit 56,
When a reset signal is input to the reset terminal RESET from the differentiating circuit 63 at the same time when the battery 20 is set in the battery storage unit 17, the program in the ROM 52 is executed according to a predetermined procedure to perform data processing, and input / output is performed. Data is transferred between the switch unit 61, the voice generation device 57, and the melody generation device 58 via the ports P _{00 to} P ₅₃ provided in the device 54.

As described above, the switch portion 61 is composed of one operation switch 13 operated from the front surface 8 side of the main body case 12 accommodating the timer unit 2 and four setting switches 34 operated from the lower surface 16 side of the main body case 12. To be done. A normally open on / off switch 31 is used for each of the switches 13 and 34.
4 and the other end is grounded by a resistor 65 to control unit 5
By individually connecting to the input ports of 6, the "H" signal is applied to the control unit 56 when each of the switches 13 and 34 is turned on to notify the operation status of the switches.

As the voice generation device 57, for example, LC8100 which is a PARCOR type voice synthesis IC is used. START
In conjunction with the input of the start signal from the control unit 56 to the terminals, the word selection terminals C _{0 to} C ₄ are specified by the 4-digit binary signal applied from the control unit 56. A series of words such as "Good night" is output from the output terminal DA.

A so-called melody IC such as SVM7793 is used for the melody generator 58. When a 3-digit binary signal is applied from the control unit 56 to the melody selection terminals MS1 to MS3, the melody specified by the value of the binary signal is linked to the application of the start signal to the start terminal MT. Is output,
Forced stop is possible by applying a stop signal to the STP terminal.

The output signals from the voice generating device 57 and the melody generating device 58 are input to the amplifying device 59, amplified to a predetermined size, and then sounded by the speaker 14 attached to the upper case 10. The power supply terminal V _cc of the amplifier 59 is connected to a switching unit 62 equipped with a switching transistor 66 that can be turned on and off under the control of the control unit 56, and a changeover switch 69 that is turned on and off in conjunction with the plugging and unplugging of a jack 67. The power source 64 is connected to the power source 64, and normally the transistor 66 of the switching unit 62 is turned on only during the period when the voice generator 57 or the melody generator 58 is in an operating state to prevent extra power consumption in the amplifier 59. However, when the input side of the amplifier circuit 59 is connected to the audio output terminal of the television or the like by inserting the plug into the jack 67, the amplifier device 59 is forcibly operated regardless of the operation of the control unit 56. It turns on and operates as a normal amplifier. A large-capacity smoothing capacitor 70 and a separating diode 71 are connected to the power supply unit 64 in order to prevent the applied voltage to the control unit 56 from changing due to the ON / OFF operation of the amplifier 59.

FIG. 6 and FIG. 7 show the flow of control of the entire electric circuit by the program stored in the ROM 52 of the control unit 56.

FIG. 6 (a) shows the outline of the overall control flow, and the program is started (step 80).
Then, after the work area or stack area in the RAM 51 is initialized, a standby state in which an input from the switch unit 61 can be accepted (step 8)
3). When the reserved time is reached in this standby state (step 84), alarm processing A according to preset reservation contents is performed, and word selection, weekly reservation provided in the timer setting section 18 provided on the lower surface 16 side of the timer unit 2, When it is determined that the setting switch 34 for daily reservation and the reservation cancellation or the operation switch 13 projecting to the front of the character doll 3 is turned on, the data processing (B) corresponding to each switch operation (steps 84 to 89) is performed. ~ E) is performed, the process returns to the standby state of step 83.

FIG. 6 (b) shows the flow of an interrupt subroutine for performing the above switch operation, updating various counters, and checking the reserved time. In the present embodiment, the interrupt process is forcibly performed every unit time of 0.25 seconds except in the interrupt disabled state.

When entering a subroutine (step 101), step 1
After subtracting 1 from the value of the minute counter in 02, it is determined in step 103 whether or not the value of the counter has become 0. In this embodiment, at the time of initial setting (step 81) and step 104 in FIG. 6 (a), the value of 239 is set in advance in the minute counter, and interrupt processing is performed every 0.25 seconds to subtract 1 from the set value. If the determination in step 103 is NO, the process proceeds directly to step 111. If the determination in step 103 is YES, it is determined that one minute has passed since the previous counting time.
After advancing the current time by 1 minute in the next step 105, the presence or absence of an alarm request at that time is determined in steps 106 to 110. That is, the reference time and the reserved time are compared every one minute of the reference time (step 10
7) If it is determined in step 108 that the two match, the start address of the reserved area storing the reservation content is set in the alarm area (step 109). In this embodiment, up to three sets of alarm requests can be set in the alarm area, and three sets of reservations including different alarm requests at the same time, or requests that are not the same time but have timed up during alarm processing are reserved. It is possible to keep the reservation in the control unit 56 at all times, and therefore, it is possible to carry out step 1
When the alarm area becomes full in the judgment of 06 and it is not possible to reserve more, if all the reserved times have been inspected in step 110, the process proceeds to the next step 111.

Steps 111 to 115 are processing steps of various timer counters set and used in the program. In step 111, it is determined that the 20 second or 3 minute timer is operating because the timer flag is set. For example, set the value of the timer counter to 1
Is subtracted (step 112). Then step 113
If it is determined that the value of the timer counter has reached 0 and has counted up, the timer flag is cleared to return to the initial state (step 114), and then the count value of the 2-second or 5-second timer is reset. The value is decreased by 1 (step 115), and the timer processing is ended.

Steps 116 to 118 are steps relating to the switch operation status inspection processing. That is, the switches 13 and 34 are read and checked in step 116, and the switch flag is set (step 118) only when it is determined in step 117 that the switch has changed from the off state to the on state, and the subroutine is called. Exit (step 119). Therefore, the on / off state of the switch is sampled at intervals of 0.25 seconds which is the interrupt processing rate by the subroutine, and even if the same switch is continuously pressed or chattering of the switch occurs, the switch operation is judged once and the control unit judges. Prevent malfunction.

FIG. 7 (a) shows a flow of the alarm processing A when the alarm request data is set in the alarm area due to the reservation time and the current time being coincident with each other in the interrupt subroutine in FIG. 6 (b). . When the processing is started (step 140), 2 is executed in step 141.
If it is determined that the second or 5 second timer is already operating, wait for the timer to time out, and after a certain interval is provided between the timer and the preceding process, clear the switch area (step 142). The input from the switch unit 61 can be accepted, the word selection and the alarm end flag are cleared (step 143), the power of the amplification device 59 is turned on (step 144), and the preparation for the alarm processing is completed. 145-1
The process moves to the alarm display cycle indicated by 67.

In step 145, first, the number of times the alarm is repeated is set corresponding to the alarm content to be displayed. In this embodiment, a light and short chime sound is produced in step 146, a voice consisting of a series of words corresponding to the notification content is provided in step 151, and a known melody arranged for a predetermined time is arranged in step 159. Sequentially pronounce each and step 147.1 between each pronunciation
2 by activating the 2 second timer at 52.163
One display cycle has a time interval of seconds. Then, for the wake-up call with the selected word "Good morning" and the good-night call with "Good night", the above cycle was repeated 3 times, and when the other words were selected, the display cycle was executed only once. After that, the process goes out of the alarm display cycle in step 165 and goes to step 168. If it is determined in step 155 that the reserved code has the code number 1 or 2 of "Good morning" or "Good night", the melody corresponding to the word is selected in step 158, but in the case of other words. , Step 156
And 157, the value of the melody counter is sequentially shifted, and the tune is changed every alarm processing.

Furthermore, when there is no sound for 2 seconds between each pronunciation (steps 149 and 15
4.167) and when the melody is pronounced (step 161)
As long as the signal input by pressing the operation switch 13 projecting to the front of the character doll 3 is accepted, even if it is in the middle of the alarm display cycle, the process exits from the cycle and moves to step 168, even if the melody is being sounded. In step 168 to step 172, the START signal applied to the melody generator 58 is stopped, and at the same time, the STOP signal is sent to forcefully stop the melody being displayed.

When the display cycle is completed as described above, first, the timer for 5 seconds is started (step 173), the switch area is cleared (step 174), and the switch input can be accepted. Further, in step 175, the alarm display cycle is executed. The head address of the reserved contents saved is saved, and the number of alarm request data is set to -1 in step 176.
After that, in step 177, it is judged whether or not the requested data remains in the alarm area. This judgment is Y
If it is ES, it is understood that all the alarms that need to be processed at this moment have been processed, so the amplification device 59 is stopped (step 178), the alarm end flag is set (step 179), and a further 3 minute timer is set. By starting (step 180) and clearing the switch area (step 181), the cancellation of the reservation can be accepted and the alarm processing B is ended (step 182).

If the determination in step 177 is conversely NO, it can be known that a plurality of reservations have been made for the same time, or there are other reservations that have timed up during the alarm processing.
At step 183, the alarm request data is shifted by one stage and the next data is taken out. In this embodiment, the input of the cancel switch is accepted until the 5-second timer started in step 173 expires in step 189 without immediately processing the retrieved data (step 18).
4) When the cancel switch is turned on, the reservation of the executed alarm saved in step 175 is cleared (step 185), the reservation is canceled, and then the melody of the processing success image is output (step 186). The switch area is cleared (step 187) and the 2-second timer is started (step 188) to proceed to step 1
A time interval of 2 seconds is compulsorily set after the 86 melody output. If it is determined in step 189 that the timer for 2 seconds or 5 seconds has expired, step 19
After clearing the switch area with 0, step 1 again
Returning to 45, the alarm display cycle for the next alarm is executed.

FIG. 7 (b) shows the flow of the word selection process B in FIG. 6 (a). When the process starts (step 191), the transistor switch 66 is controlled by the control unit 56 in step 192.
After sending the ON signal from the device to activate the amplifier 59,
In step 193, it is determined whether the word selection switch is turned on while the 20-second timer is counting. If this determination is YES, it is determined that the word selection switch has already been turned on within 20 seconds and the word selection processing C has been performed, and the display of the next word is requested.
After advancing the number of the word selection code by 1 (step 194), the 20-second timer and flag are set (step 19).
In step 5), other processing commands such as reservation and cancellation are accepted, and a word output request is issued to the voice generator 57 (step 196) to output the word specified by the word selection code number. Let After that, the operation of the amplifying device 59 is stopped (step 197) and the switch area is further cleared (step 198) so that the next switch pressing operation can be accepted (step 199).

FIG. 7 (c) shows the flow of the reservation process C in FIG. 6 (a). When the reservation process starts (step 200), first, at step 201, it is judged if the 20-second timer is counting. If the determination is NO,
Immediately, the switch area is cleared (step 208) and the reservation process is not performed and the process ends. However, if the determination in step 201 is YES, it is determined that the word to be processed next is voluntarily selected by pressing the word selection switch and performing the word selection processing B described above, and the processing proceeds to the following reservation processing. .

First, after resetting the counting timer for 20 seconds and the flag in step 202, the amplifying device 59 is operated (step 203) and the reserved area is checked (step 204). If it is determined in step 205 that the reserved area is not empty, more reservations have already been made and further reservations cannot be made. Therefore, the melody of the unsuccessful image is output from the melody generator 58 (step After 206), the amplification device 59 is stopped (step 207) and the process ends.

On the other hand, if the determination in step 205 is YES, interrupts are prohibited between steps 210 and 212 and the current time and week number are fetched (step 21).
1) Then, the time and week number are set in the reservation area (step 213). The current time and the week number may correspond to the Japanese standard time, but in the present embodiment, the time when the battery 20 is set is used as a reference, and each day thereafter is in a minute unit from 0 to 1439. In addition to the current time, the day of the week is specified and displayed by associating each day of the week from the reference time with the week number from 1 to 7.

Next, at step 214, it is judged whether or not the word selected prior to the reservation processing is a special word representing "start" such as "beginning". If the determination is NO, the process directly proceeds to the next step 216, but if the determination is YES, the timer is operated by forcibly moving back the reserved time set in the reserved area for 5 minutes and resetting. At the time of alarm processing, it is possible to notify the television program 5 minutes before the actual start of the program, so that the program recording can be sufficiently prepared. Next, at step 216, whether the reservation content is a reservation content to be made every day such as wake-up call, that is, the sixth
It is determined from the contents of the switch area whether the weekly switch is turned on in step 86 of the figure (a) or the daily switch is turned on in step 87. If the determination is YES, the week number set in step 213 is set to 0. Then, it is displayed that the reservation is made every day (step 217).
Further, in step 218, the code number corresponding to the word displayed during the word selection process shown in FIG. 7 (b) is set in the reserved area and one group of reservations is completed. The melody output request is issued (step 219) to inform the operator that the reservation has been made normally. After that, the power supply to the amplification device 59 is stopped (step 220), the switch area is cleared (step 221), and the series of reservation processing is ended (step 222).

FIG. 7 (d) shows a flow of the cancellation process D in FIG. 6 (a), and the process is started (step 23).
0), the drive voltage is first applied to the amplifying device 59 to operate it (step 231), and it is further determined in step 232 whether the 3 minute timer is counting. The 3-minute timer is set at the end of the alarm processing A described above, and if the determination is YES, it is understood that it is within 3 minutes from the end of the alarm processing A. Therefore, in such a case, after moving to step 233 and resetting the three-minute timer and the flag (step 233), the execution address for alarm processing saved in step 175 of FIG. Step 234),
Further, the reserved area corresponding to the execution address is cleared (step 235), and the reserved content after the alarm processing is erased.

On the other hand, if the determination in step 232 is NO and the cancel switch is pressed regardless of the alarm processing, it is further determined in step 236 whether the 20-second timer is counting. The 20-second timer is set only when a predetermined word is selected in the word selection processing in step 195 of FIG. 9 (b), and if the determination in step 236 is NO, it is determined to be a malfunction and amplification is performed. Although the device 59 is stopped and terminated (step 239), if the determination is YES, it can be determined that the canceling process is positively desired, so the process proceeds to the following step 240 to perform the canceling operation.

First, in step 240, after resetting the 20-second timer and flag to return to the initial state, the OK flag for discriminating and displaying whether or not the processing is successful is reset (step 241). Next, in step 242, the leading address in the reserved area is set, and it is determined in step 2 whether or not it matches the word selected in the word selection processing prior to the cancellation processing.
Done at 43. If the determination is NO, the process proceeds to step 246 to set the address of the next reserved area,
The determination in step 243 is continued until the entire reserved area is checked in step 247.
If the determination result in step 3 is YES, the corresponding reserved area is cleared (step 244), the OK flag is set (step 245), and the cancellation process is sequentially performed to erase all the reserved contents with the same word. To do.

Next, in step 248, it is determined whether or not the OK flag is 1, and if the determination is YES, it is determined in step 244 that at least one reservation cancellation has been executed.
In step 250, the melody of the successful image is output from the melody generator 58. On the contrary, if NO, it is determined that the corresponding reservation was not found and the reservation was not canceled at all. Therefore, the melody of the unsuccessful image is output. Is requested to the melody generator (step 249). Then, a 2-second timer is started to set a time interval between the next display operation (step 251), the amplification device 59 is stopped (step 252), and the switch area is cleared (step 253). The cancellation process D is ended (step 254).

FIG. 7 (e) shows the flow of the play processing E in FIG. 6 (a), except when the operation switch 13 of the timer unit 2 is pressed during a specific period during alarm processing. The process is started, and a melody or a word can be randomly output in association with the pressing operation of the operation switch 13. That is, the process starts (step 260)
Then, the amplification device 59 is started (step 261) and then the current time is taken in (step 262). Here, in the data table, data such as chord numbers for specifying the melody and words to be output or the display contents are randomly set in advance, and step 262 is performed.
The address in the data table is calculated in step 263 using the numerical value of the current time obtained in step 263, and the data in the data table is extracted from the address (step 264).
If it is determined in step 265 that the extracted data is a word, an output request is issued to the voice generating device 57 (step 2
66) If it is a melody, an output request is issued to the melody generator 58 (step 267), then the energization of the amplifier 59 is stopped (step 268), the switch area is cleared (step 269), and the process is ended. (Step 270). The sound is continuously generated every time the operation switch 13 is pressed, and the display content is randomly selected from a plurality of reserved words or melody groups, which is surprising. The acoustic display is made by combining the words or the melody.

[Effects of the Invention] As described above, the present invention has a practical function as a normal timer device and, in addition to the playable function of randomly outputting a word or melody in conjunction with the switch operation, the timer is provided. While not operating as a device, you can enjoy the unexpectedness of any combination of words,
There is an advantage that a timer device whose practical use period is limited to a short time can be effectively used.
