2. Description of the Related Art A conventional electronic device relating to a guitar having a guitar effect and a guitar effect is as follows.

In describing the prior art, the terms are
Use as follows: The guitar effector is simply expressed as an effector, and the electric guitar and the electric bass guitar are the same except that the number of strings is different, and will be simply expressed as a guitar below. The central processing unit is simply the CPU
Express. Digital signal processors are simply DS
Express as P. Both the CPU and the DSP generate the same electromagnetic waves as those of the microcomputer, which are harmful to humans.

There is an electronic device for a guitar called an effector that changes the tone color of the guitar into various tone colors when playing the guitar. You can use this to create a powerful and exciting sound when playing rock, and various guitar effectors are commercially available. This effector
It uses a CPU and DSP to produce various sound effects, is portable, and has become an indispensable tool for rock musicians. In addition, products for guitar-related electronic devices that incorporate this effector into a guitar or amplifier are also on sale. Regarding this. A conventional effector has a structure as shown in FIG. Explaining in the figure, the tone color signal drawn by the guitar 2 is input to the microphone jack 75. The input tone color signal is A
The D converter 4 converts the analog signal into a digital signal. The obtained digital signal is subjected to predetermined processing by a digital signal processor DSP5 which is a kind of CPU of the central processing unit to produce a sound effect. The effect sound of the created tone color is amplified by the amplifier 15, and the effect sound signal is output to the outside. This is greatly amplified by an external amplifier, the speaker vibrates the air, and is output to the space. However, there is no prevention of electromagnetic waves that are harmful to humans and that are generated by microcomputer board circuits and the like. Electromagnetic waves are being generated from the signal lines and data lines of the microcomputer board. However, with guitars and amplifiers, the back cover is simply covered with plastic. It is not installed in gnd either. It has been pointed out that electromagnetic waves are harmful, such as inhibiting the synthesis of human melatonin. The RAM 7 temporarily stores data when making a tone color sound effect. The program of the DSP 5 is transferred to the DSP 5 by the second CPU 180, and the DSP 5 executes the program to execute the tone color processing. Apart from the above, the second CPU 180
Sends data to the display circuit 31 to display a number on the 7-segment LED display 32. The second CPU 18
0 reads the input of the setting switches 53 and 54, and injects the program into the DSP 5 according to the operation switches 53 and 54 so that the DSP 5 executes the predetermined program. The second CPU 180 outputs the MIDI data to the MIDI connector 58, and the personal computer 41 transfers one of the tone color signal and the tone color signal including the effect sound as tone color data.

The personal computer 41 outputs a sound from the speaker of the personal computer 41 in accordance with the sent tone color data. A dry battery 170 is used as a power source of the effector 1. Some can work with AC adapters. Reset circuit 190
Uses a reset IC to prevent the DSP 5 and the second CPU 180 from running away when the voltage of the power supply falls below a specified value, whereby the effector 1 stops when a reset is applied.

FIG. 23 is an external view of a guitar, which is a guitar-related electronic device including the guitar effector shown in FIG. 22. This is called an amplifier-embedded guitar in which an amplifier 194 and a speaker 16 are integrated with the guitar 2. Fig. 25
The effector 1 is attached. Guitar 2 has
A plastic plate 38 is attached to the back of the guitar as a back cover. Further, the string 74 is stretched, and this vibration is converted into a tone color signal by the pickup 73. The obtained tone color signal is sent to the effector, and a predetermined effect sound is added to the tone color signal, amplified, and sent to the speaker 16. The speaker 16 vibrates according to this signal and outputs a sound. The 7-segment LED display 32, the operation switches 53 and 54, the battery 21, and the microphone jack 56 are connected to the effector 1. FIG. 24 is an external view of an amplifier of a guitar electronic device including the guitar effector shown in FIG. 23. This is an amplifier that amplifies the guitar tone color signal and outputs a loud sound.
The effector of FIG. 24 is incorporated. The speaker 16 is attached to the amplifier body 273. In this amplifier, a guitar tone color signal is input from the microphone jack 75 and input to the effector 1. As described above, the effector 1 produces a sound effect, which is amplified by the amplifier 195,
The speaker 16 is vibrated. The operation switches 53, 54 and the 7-segment LED display 32 all have the same function as in FIG. The 7-segment LED display 32 has various types of sound effects, and displays which sound effect is selected. There are various types of sound effects, such as distortion of distorted sound (denoted as DIST), sound effects called delay and chorus, and pitch-shifting tone color. The power source of the amplifier is generally 100 VAC, which is a commercial power source, but the dry battery 21 may be used in a small amplifier.

[Problems to be Solved by the Invention]

In the conventional guitar effector, there is a problem that the electromagnetic waves of the CPU, DSP, etc. of the microcomputer board are generated, which is harmful to humans and harmful to the production of melatonin. Sustainer drivers also generate electromagnetic waves. Further, since the battery is mainly used for the power source of the effector, there is a problem that the usage time is short.

Further, before the battery runs out, there is no indication in advance that the battery will run out, and the effector suddenly stops operating. Such anxiety has a bad influence on the artist's artistic sensibility, and there is also a problem that he cannot concentrate on the performance.

Further, there is another problem that the remaining usage time is not displayed because there is no standard for how much the battery can be used.

Separately from this, in order to change the tone color signal of the guitar into various effect sounds by the effector, this is digitized and stored internally as data, which is referred to as setting data. The setting data is stored in the effector by directly inputting it by pressing a button with a finger on the effector. However, this series of work was
Since the operation is performed by checking the LED of the segment LED or the display on the dot for confirmation, the operation and confirmation of the setting data are complicated, the operability is poor, and the display is difficult to see. Furthermore, the method of saving this setting data is only to save it in the memory of the effector body, there is no other saving method,
Therefore, when the effector fails, the setting data must be input again to the new effector, which is a labor-intensive problem.

Further, this setting data is a 7-segment LE.
Since the display devices on D and dots are mainly used, there is a problem that the amount of data viewed at one time is small.

Regarding this, in recent years, an effector of a type using a 5 * 7 matrix alphanumeric display has been put on the market, and although some improvements have been made, this type of effector is expensive and has a problem. there were.

Further, even in this type of effector, there is a problem that the character information is still small, about 20 characters * 4 lines, which is clearly hard to see as compared with the screen of a personal computer and the display function is low.

Apart from this, regarding the price of the effector, the effector is the IC of the AD converter of the tone color signal of the guitar, the CPU of the central processing unit for processing the tone color data into the sound effect, or one of the CPUs. Seed DSP
Is being processed in. Further, the tone color effect sound processed by the IC of the central processing unit CPU is sent to the IC of the DA converter and becomes an analog effect signal. The display of the effector setting data is processed by the central processing unit. As described above, since the effector is substantially configured by using a plurality of four ICs, there is a problem that the cost is high and the board size is large.

Another problem is that there is no confirmation sound when the key of the effector is operated, and the confirmation work is difficult.

Another problem is that since a plurality of ICs are used substantially, the current consumption is large and the battery does not last long.

Further, apart from this, regarding the rhythm sound different from the effect sound of the effector,
This is a process that converts the tone signal of the guitar into a sound effect, and this sound effect does not have a rhythm sound that repeats with the rhythm.Therefore, when practicing the guitar, a rhythm sound is generated by an electronic device called a rhythm machine and practiced. Sometimes you need to. At this time, you also need to buy a rhythm machine,
There was a problem that the effector had no rhythm sound. In addition, even if the effector's setting data is damaged for some reason, or the function of the effector is low such that the battery voltage is low and the voltage is below the limit voltage for maintaining operation, the current effector will not Since the abnormality is found, there is a problem that the performance is stopped and it is necessary to urgently respond to this. There is a problem that the notice of this abnormality is not displayed when the power is turned on.

Apart from this, in the conventional effector, there is a problem that the person who operates the effector has to approach the effector in order to confirm which sound effect is used by operating and pushing the operation switch. It was There are problems with the various effectors described above.

The electronic device related to the guitar to which the effector is applied has the following problems. As a guitar-related electronic device, there is a guitar with a built-in effector in which an effector is incorporated in a guitar body. In addition, there are guitars with built-in effectors and amplifiers that have speakers attached to them. However, these effectors have no rhythm sound or accompaniment function,
There is a problem that it is difficult to practice when people practice. Regarding this point, an effector having an accompaniment function called KARABAN was sold by the Kawai musical instrument, but this was because the accompaniment data was written in the ROM and could not be rewritten by the effector. This is something you cannot practice your own song. It is the same form as the so-called hit karaoke. The present invention is an effector having an accompaniment function for the purpose of allowing the effector itself to write an accompaniment again and reproduce it at a later date, and a built-in guitar or amplifier. Further, the setting data is not read or the setting data is not recorded by using an optical storage medium such as a CD-ROM, a CD-R, a DVD-ROM, a DVD-RW. In addition, the processing program of the sound effect of the tone color (sound effect processing software, rhythm sound processing software) cannot be read by the drive unit, and the program cannot be executed by the CPU. There was a problem that I could not input and output. There is also an amplifier with a built-in effector that integrates the effector into the body of the guitar amplifier. These guitar-related electronic devices also have the same various problems as those described for the effector.

Another object of the present invention is to make the battery last longer by reducing the current consumption of the effector. Furthermore, the purpose is to give advance notice that the battery is dead, and if the effector is abnormal, the abnormality will be displayed when the power is turned on so that the player can play with confidence. Furthermore, the purpose is to make it easy to check, operate, save, and replace effector setting data. In addition, the effector is connected to a personal computer or electronic device only with the MIDI standard MIDI,
There is a limit to the operation, and it is also aimed at improving this.

Further, it is also intended to display setting data directly on the monitor from the effector.

Furthermore, it is an object to make the effector compact at a low cost.

Further, it is another object of the present invention to save the effector setting data by a method other than the effector main body.

Further, it is intended to generate a rhythm sound in the effector.

Further, the object of the present invention is to remotely control the effector, to select the volume and effect sound, and to effectively turn on / off the power of the effector.

In addition to the above, the guitar-related electronic device of the present invention has a guitar and an effector integrated with each other, and is intended for a guitar having an accompaniment function of generating a rhythm sound.

Further, in the amplifier in which the amplifier and the effector are integrated, the same contents as those of the above-described effector and a guitar or an amplifier with a built-in effector for the purpose of allowing the effector itself to write an accompaniment again and reproduce it later. .

[0028]

In order to achieve the above object, the effects and the electronic device for effector for guitar of the present invention carry out the following means.

A metal plate or a magnetic plate that absorbs electromagnetic waves is wired to the GND of the circuit on at least a part or the entire surface of the human side of the guitar and the amplifier. It may be one that can absorb electromagnetic waves without wiring.
In the effector, in order to make the battery last longer, the power supply current of the effector is reduced when the strings are not vibrated, in other words, when the tone color signal of the guitar pickup is substantially silenced. Therefore, first, a timbre signal detection circuit is provided to detect a silent state. The tone color signal detection circuit detects when there is no tone color signal from the guitar pickup and sends a pulse to the CPU immediately or after a certain period of time, and outputs a silence signal as an interrupt signal or a 0 or 1 voltage to the general-purpose port. Inform.

Further, a one-chip CPU having a mode in which the CPU consumes less current in a silent state is adopted. C
When the PU makes the clock slower than usual, the current consumption decreases in proportion to the clock speed. Therefore, when the clock is dropped, the current consumption of the effector decreases. Further, the CPU has a sleep instruction, and when this sleep instruction is executed, the CPU stops executing the program and sleeps.
The current consumption is extremely low. In addition, in some cases
Depending on the CPU, there is also a standby mode, which is a standby mode, and execution of the program may be stopped. Furthermore, when a tone color signal is input to the effector from the tone color signal detection circuit in this stopped state, an interrupt signal is generated and the CPU
And let the program rerun, allowing the effector to function as it originally did.

Furthermore, it is determined whether the silent state has passed for a predetermined time by C
The PU also monitors from the general-purpose port, and after a certain period of time, also causes the CPU to reduce the current consumption.
The general-purpose port has many terminals, and the usage status of this general-purpose port is shown below in the part that collectively shows the connection destination of each terminal.
Here, the general-purpose port will be generically described.

As another method, as a method of making the battery last longer, the display is made when the operation switch is pressed, and when the operation switch is not pressed, the display is dimmed or turned off. This saves current for the display and consequently reduces the effector current consumption. Therefore, a general-purpose port for controlling the display circuit is connected to the CPU, and the display circuit is controlled by this. Alternatively, there is also a method in which the general-purpose port is used as it is and the CPU directly provides a display circuit for displaying the general-purpose port. The CPU can turn off or turn off the display according to a command.

Even when the tone color signal is generated for a long time, the display may be dimmed or turned off depending on the person, so that the CPU obtains the tone color signal conversion data from the AD converter. To do. The CPU monitors this time,
If it lasts for a long time of, for example, 30 minutes, it is judged that it is not being played but the switch is turned on unnecessarily and that the display circuit is turned off or turned off. Since the operation switch is also connected to the CPU through the general-purpose port, when the operation switch is pressed, the CPU turns on the display circuit so that the display is performed.

In order to detect the dead battery, the battery voltage is connected to one of a plurality of input terminals of the AD converter, and the battery voltage is digitized together with the tone color processing. The AD converter is
It is connected to the CPU. Then, the table of the battery data is stored in the ROM, and the battery voltage value, abnormal / normal flag,
25 bytes consisting of 3 bytes with 1 set of remaining usage time
Create 5 types of data in ROM as a data table. When the power of the effector is turned on, the CPU compares this data table with the voltage value of the battery by a program, and if abnormal, displays the battery exhaustion on the display. If it is normal, the remaining time is displayed on the display.

The effector is provided with a MIDI connection terminal so that the effector can be connected to an electronic device such as a personal computer, a handheld computer, a word processor or a game machine.
The RS232C, USB, and external memory connectors are provided. Then, MIDI is substantially controlled by a general-purpose port of the CPU, and a transmission / reception circuit is provided. RS232C
Uses a serial input / output port of the CPU and substantially constitutes a circuit.

USB is a dedicated IC USBN9602
Is connected to the CPU to substantially form a circuit. The external memory extends the address bus, data bus, and control bus of the CPU and is connected directly to the connector to form a circuit. Then, the connectors are arranged on the outer surface of the effector. The personal computer has each of the above connectors,
Can be connected with a cable through the effector and connector.
In addition to PCs, there are similar connectors in electronic information devices such as handheld computers and game consoles.
It can be used like a personal computer.

The effector setting data is sent to the CPU by the EEPR so as to be displayed on the screen of the personal computer from the effector.
Since the OM is connected, the CPU reads the data from the EEPROM and sends the data to the personal computer through each connector. On a personal computer, there is a program called Hyper Terminal in the operating system.
In Windows (registered trademark) 95, HyperTerminal software is installed as standard. By operating this, data can be sent and received from the effector and displayed on the personal computer screen.

Further, the personal computer can send data to the effector. The data sent from the effector is automatically recorded by the HyperTerminal program, so if this is written to a floppy (registered trademark) disk of a personal computer, the effector setting data can be saved on the floppy disk.

On the contrary, data is transmitted to the effector connected to the outside in the terminal mode of the personal computer. The effector writes the data sent from the personal computer into the EEPROM that stores the setting data.

When the MIDI connector is used to communicate with a personal computer, the MIDI standard saves effector setting data and transmits setting data. The MIDI standard is a standard for transmitting the pitch of a sound, the volume of a sound, the time of a sound, and the like, and transmits and receives data to and from a personal computer, but this is mainly limited to data for reproduction.

In the present invention, a data format different from the MIDI standard data is newly created so that the MIDI connector can also transmit and receive the effector setting data in the same manner as the RS232C. For this format, specifications may be created as appropriate. For example, at the beginning of data to be transmitted, a non-MIDI standard 01234
The number 56789 is set. And 0 at the beginning of the data
If the personal computer receives the data sent when the 123456789 is installed, it is determined that it is out of the MIDI standard and a predetermined operation is performed. Then, it transmits or receives the data which is the setting data and designates the end of the day 999999.
If 9999 and 9 occur 9 times, it is judged as the end mark. The effector setting data is written from the personal computer by such a method outside the MIDI standard. In a personal computer, if data is created in accordance with this format with an editor, the setting data will be automatically transmitted or received from the personal computer to the effector using the transmission / reception function of HyperTerminal.

Further, since communication between the personal computer and the effector by TCP / IP is compatible with the Internet in the personal computer, the TCP / IP protocol is incorporated as standard with both hardware and software. Also, when using browser software such as Explorer of Internet browser and Netscape communicator, it is possible to communicate with an external electronic device by this software. The effector has a TC
When the SA7600 P / IP IC is connected, the TCP / IP IC connects to the
Enable communication with a personal computer through S232C.

In addition, TCP / IP We in the effector
b Provide a server board uCsimm, uCgardener. This is a self-supporting Web server made in Canada and housed in a compact board. The hardware and software are built in, and Linux is stored in the ROM of the flash memory.
It has been converted to OM and is operating. This board has RS232
There is a connector and a parallel port that can send and receive data by connecting to an effector.
Connect to the general-purpose port. This enables RS2 from the personal computer.
It is possible to communicate with the Web server in the effector through 32C. The Web server outputs the received data to the general-purpose port of the CPU of the effector through the parallel port, and the CPU of the effector obtains the data of the Web server from the general-purpose port. The effector uses this as setting data.

The CPU of the effector is not only the CPU but also the E
EPROM or flash memory, general-purpose port, AD
Converter, DA converter, timer, counter, serial port, clock generation circuit, low power consumption mode circuit, DSP
There is a one-chip microcomputer in which each function such as a function is integrated in one chip, a wine chip CPU, or a wine chip DSP. All are ICs of the same genus, only with different names. Especially for the DSP function, CP
Both U and DSP are central processing units, and a specialized CPU is DSP, and DSP is one type of CPU. A mixed-type 1-chip CPU having the same function as this DSP is used. For example, Hitachi SH-DS
It is a CPU of SH7065 of P series. This CPU
By setting the timer and counter of (1) by a predetermined program, a fixed-cycle interrupt can be generated, and the CPU can be interrupted at regular intervals. Here, each time the CPU receives an interrupt, the CPU activates the AD converter and the DA converter, confirms various operation switches, updates display data on the display, displays, and confirms the battery voltage.

The effector has an external memory connector. When the bus signals of the CPU and the bus signals of the CPU are substantially combined and the memory board is inserted in the external connector, the CPU reads the contents of the memory board, and vice versa. , Write data. By writing this data to the memory board, which is the setting data of the effector, the data of the EEPROM, the setting data can be saved. Conversely, when the data in the memory board is read and written in the EEPROM, the setting data such as effectors are updated. In addition to this, RAM, EEPROM, or flash memory is used as the external memory, but the external memory is not limited to this.
The setting data may be read from an optical storage medium such as -R, DVD-ROM, DVD-RW. In this case, the external memory connector becomes a drive unit for each optical storage medium. Further, although the setting data is recorded in the EEPROM of the setting memory, it may be a processing program (sound effect processing software, rhythm sound processing software) of a tone color effect sound.

The effector is provided with a monitor display circuit,
Connect with CPU. The monitor display circuit produces a luminance signal, a horizontal synchronizing signal, and a vertical synchronizing signal. This signal is output to the monitor display connector, and an external analog or digital display signal is connected to the monitor with a cable from this connector to display effector setting data on the monitor screen. The CPU uses RAM or ROM connected to the CPU that displays information on the monitor, and periodically sends effector setting data to the monitor display circuit.

Either infrared or wireless is used to communicate with the remote control electronics. In the case of infrared rays, the effector and the electronic device are provided with a light emitting element and a light receiving element, and a light emitting circuit and a light receiving circuit are provided therein. The control of the light receiving circuit and the light emitting circuit is performed by the general-purpose port of the CPU, since the CPU is used both inside the effector and the remote controller of the electronic device. Small one-chip CP for electronic devices
Use U. When remotely controlling an effector from an electronic device, a light emitting element and a light receiving element are attached to the outer surface of the electronic device.

A key switch is attached to the electronic device,
The CPU detects that the key switch has been pressed at the input terminal of the general-purpose port, and sends a predetermined pulse train to the light emitting circuit.
In the light emitting circuit, an infrared pulse is output from the light emitting element based on the pulse train sent from the CPU. The emitted infrared light becomes a voltage signal at the light receiving element of the effector, and becomes a voltage pulse signal at the receiving circuit. The CPU of the effector reads this from the general-purpose port, and according to a predetermined pulse train, the effector operates, for example, a sound effect, a sound volume increase / decrease, and a power-off operation. In addition, the power supply current may be turned off to substantially reduce the current consumption.

When data is sent from the effector to the electronic device, the CPU of the effector reads the setting data from the EEPROM, sends it to the general-purpose port, sends the data string to the light-emitting circuit from the general-purpose port, and vice versa. Drive the light emitting circuit. The light emitting element emits an infrared pulse toward the electronic device according to the pulse train sent. The emitted infrared pulse becomes a voltage pulse at the light receiving element attached to the outer surface of the electronic device, and becomes a predetermined voltage pulse at the light receiving circuit. This is a small one-chip C for electronic equipment
The PU reads the data and displays the data on the display to inform the operating state of the effector.

In the case of wireless communication, one set of transmitting circuit and one receiving circuit are provided in the effector and the remote controller of the electronic device. Attach the antenna to the effector and the antenna to the electronic device. The electronic device may be something other than a remote controller. The transmitter circuit may be a commercially available product as a transmitter substrate, and the receiver circuit may be a commercially available finished product as a receiver substrate. In both cases, a radio wave is output only by inputting a pulse signal into the transmission circuit. Further, the receiving circuit also operates so that a voltage signal can be obtained when an antenna is attached and radio waves enter. Although the present invention employs a simple type transmission circuit and reception circuit that amplitude-modulates weak radio waves using a band of 20 MHz, the present invention is not limited to this, and the FM transmission board and the FM reception board are used as described above. You can also do it. For example, in the finished product of FM transmission board,
A BISTOU TAKE 2CMFM transmitter board is used. Further, as the receiving board, a TA7792FM radio receiving board can be used as well. However, the present invention is not limited to this, and a band other than the FM band or a transmission / reception board using a spread spectrum method other than the FM modulation can be used. The electronic devices include one-chip CPU, key switch, antenna and transmission circuit,
Built-in receiver circuit, indicator, battery. Since this radio wave is weak, it does not harm people.

The effector also has a built-in CPU, operation switches, antenna, transmitter circuit, and receiver circuit. When you press the key switch of the electronic device, the CPU senses this,
A predetermined pulse train is sent to the transmitting circuit. The transmission circuit emits a predetermined radio wave from the antenna according to the pulse train.
The radio wave emitted from the antenna enters the antenna of the effector, is converted into a voltage by the receiving circuit, and is converted into a pulse. This pulse is read from the general-purpose port of the CPU, the CPU converts the pulse into a pulse train, and receives an operation command from the electronic device. The CPU checks whether this pulse train is an instruction for a predetermined operation, and changes the volume of the sound volume, changes the sound effect, and substantially turns the power on and off, as in the case of remote control operation using infrared rays.

When data is sent wirelessly from an effector to an electronic device, when the operation switch of the effector is pressed, CP
U reads this and sends a pulse train to the transmission circuit from the general-purpose port. According to the pulse train, the transmission circuit directs radio waves to the electronic device and emits them from the antenna. The electronic device converts the electric wave entering from the antenna into a voltage signal by the receiving circuit and sends the pulse to the small CPU. The CPU converts the pulse into a pulse train, performs a predetermined operation from the data, and displays it on the display.

In an integrated guitar in which an effector is built into the guitar, the effector is provided with any accompaniment function such as a rhythm sound or a recorded performance. As for the rhythm sound, the above-mentioned generation method is used in which the CPU generates a rhythm sound by a periodic interrupt, but other methods can be adopted if the action is the same.

The effector for a guitar constructed as described above has a function of canceling the electromagnetic wave generated by the microcomputer board toward the person by the electromagnetic wave prevention sheet plate by the electromagnetic wave of the opposite phase of the electromagnetic field by the eddy current. In addition, the electromagnetic wave electromagnetic wave prevention sheet has an effect of blocking a magnetic field generated from the microcomputer board and directed to a person. Also, when the tone color signal of the guitar becomes silent, the tone color signal detection circuit detects it, and the CP of the effector is detected.
Notify U through the general-purpose port. With this news CPU
Operates to turn off the power supply current off circuit of the display circuit with the power FET, turn off the indicator, and reduce the current consumption of the effector.

In the same manner as described above, the CPU executes the sleep command by the notification from the detection circuit, reduces the current consumption of the CPU, and consequently reduces the current consumption of the effector.

Similar to the above, the frequency of the clock generation circuit in the one-chip CPU is set to a higher state by the notification from the detection circuit, the CPU clock is slowed down, the current consumption of the CPU is reduced, and the effector consumption is reduced. It works to reduce the current.

When the operation switch of the effector is pushed, a signal is input to the general-purpose port of the CPU, the CPU operates the display circuit, and the brightness of the 7-segment LED display increases. When the operation switch is released, similarly, the CPU turns off the current of the display circuit, and works depending on whether the 7-segment LED display is turned off or turned off. CP when the operation switch is released
It senses from the general-purpose port of U, and after a certain period of time, the current of the display circuit is operated by the signal from the CPU so that the 7-segment display is turned off or turned off after a certain period of time.

The voltage of the battery of the effector is converted by the AD converter, and when the CPU has a value other than the predetermined value, it is determined to be abnormal. The CPU sends this abnormality signal to the display circuit, which works to display the abnormality on the display.

The battery voltage of the effector is converted by the AD converter, and the remaining usage time of the battery can be calculated from the data table in which the predetermined value is written by the CPU.
Sends to the display circuit, and works to display the remaining battery life on the display.

USB or RS232 as the effector
Since it has a C connector and a circuit, it works so that it can be connected to a personal computer with a cable.

Since the light emitting element and the light receiving element and the light emitting circuit and the light receiving circuit are provided in both the effector and the remote controller which is one kind of electronic equipment, when the infrared ray is emitted from the remote controller, the light receiving element of the effector detects this. The light receiving circuit detects and converts it into a pulse. This pulse is sent to the CPU through the general-purpose port of the CPU to change the setting data of the effector and various kinds of operation of the effector so that the personal computer can operate the effector.

Since the effector has a USB connector, when it is connected to a personal computer with a cable,
Effector setting data can be sent to a PC. On a personal computer, the transmitted data is displayed on the screen, so the setting data is displayed collectively on the screen. Similarly, the effector has a RS232C connector, and the connector is different, and the same operation as described above is performed.

There are antennas for effectors, wireless transmission circuits, and wireless reception circuits. This is connected to the general-purpose port of the CPU, so when there is a radio wave in the effector antenna,
The receiving circuit makes a pulse, and this pulse is transmitted to the CPU. Further, in the CPU, since a pulse is sent from the general-purpose port to the wireless transmission circuit, a radio wave is sent from the wireless transmission circuit to the antenna, this radio wave enters the receiving circuit, and reaches the remote controller.
In the wireless remote controller, the radio waves sent from the effector are received by the antenna, a voltage is generated, the receiving circuit converts this into a pulse, and the one-chip CPU of the wireless remote controller converts the pulse into data and processes the data. The processed information is displayed on the display unit of the wireless remote controller.

When transmitting effector setting data to the infrared remote controller, the CPU of the effector reads the setting data from the setting memory and sends it to the infrared light emitting circuit. In the infrared light emitting circuit, the light emitting element emits more infrared rays toward the infrared remote controller in accordance with the transmitted signal. In the infrared remote controller, this infrared ray is converted into a pulse signal by a light receiving element attached to the outer surface of the infrared remote controller, and this pulse is converted into data by a one-chip CPU in the infrared remote controller. The digitized data is displayed on the display portion on the outer surface of the infrared remote controller by using an LED or liquid crystal.

On the contrary, when operating the effector from the infrared remote controller to perform remote control, when a person presses the key switch attached to the outer surface of the infrared remote controller, the CPU in the infrared remote controller detects this and To the light emitting circuit in a predetermined format. In the light emitting circuit, infrared rays are emitted from the light emitting element on the outer and outer surfaces of the infrared remote controller toward the light emitting element of the effector in accordance with the transmitted data. The emitted infrared rays are converted into voltage signals by the light receiving element provided on the outer surface of the effector. The converted signal is sent to the general-purpose port of the CPU and input to the CPU. The CPU functions to update the setting data in the effector, increase or decrease the volume of the tone color signal output, and turn on / off the power of the effector based on the transmitted data.

When connecting the personal computer and the effector, since the effector has a USB or RS232C connector, the effector is connected to the personal computer with a cable. The effector is equipped with a dedicated IC for USB control, and CP
Combined with U, the CPU sends the data to the USB IC. The USB IC sends a predetermined signal to the USB connector. The signal input from the USB connector is USB
Is converted into predetermined data by the IC and sent to the CPU. USB that is installed as standard in the personal computer
Since RS232C and MIDI connectors are provided, these are used.

The data sent from the effector is R
Through S232C, it is saved in the floppy disk that is standardly installed in the personal computer. Since the personal computer has a terminal mode, Windows 95 HyperTerminal automatically records all the received data of the sent data and saves it on a floppy disk. On the contrary, the contents of the floppy disk can be changed by RS232C or US
B can be transmitted to the effector. In this way
The data sent from the personal computer is the USB IC unit.
The signal is received by the SBN9062B or, in the case of RS232C, is input to the CPU through the ICMAX 232, which is converted into a voltage signal, into the serial port of the CPU. CPU
Determines the data of the serial port, updates the setting data of the effector, switches to the data transmission mode to the personal computer, and performs a predetermined operation. It works so that the operating status of the effector can be displayed on the personal computer.

The personal computer is also equipped with MIDI as standard, which is almost the same as the above-mentioned RS232C and USB. In the case of MIDI, a dedicated IC is not necessary, and it works by substituting the general-purpose port of the CPU of the effector for substitution.

Further, the effector obtains the data sent from the personal computer through the USB or RS232C, writes the data in the EEPROM directly connected to the CPU, and updates the setting data.

The MIDI connector of the effector is a CPU
Since it operates with the general-purpose port of, the program can send and receive data other than the MIDI standard. The personal computer also has a MIDI connector, and this is also a program from the CPU of the personal computer, and the sending and receiving of data other than the MIDI standard comes by the program. Therefore, create a protocol for sending and receiving appropriate data. Since it is limited to the inside of the effector, there will be no problem if products other than the MIDI standard are not connected to other MIDI standards. By this data transmission / reception, the personal computer sends data to the effector, and the effector uses the received data to update the setting data and changes the content. In addition, by sending data from the effector to the personal computer, the effector setting data and operating status can be displayed on the personal computer screen.

Dedicated IC for TCP / IP of effector
Since the SA7600A is connected to the CPU, TCP
/ IP allows the effector to be connected to a personal computer or electronic device such as a remote controller. The CPU of the effector is TC
When data is sent to the P / IP IC, the TCP / IP IC
, A TCP / IP IC automatically performs a dedicated procedure, and this data is sent to a wireless transmission circuit or each connector. In TCP / IP, an RS232C connector is used to connect a TCP / I from an effector to a personal computer.
You can send and receive data with P. Since TCP / IP has become a standard protocol in the world of the Internet, it can be easily connected by using the built-in Windows 95 of a personal computer. The CPU of the effector sends the data to the TCP / IP IC, and the TCP / IP IC
From RS2 of PC by cable through RS232C
The 32C connector allows the personal computer and effector to send and receive data.

We of another substrate mounted in the effector
In the server board b, the general-purpose port of the CPU of the effector and the parallel port of the web server board are connected, and the CPU server can send and receive data to and from the web server board. Since the Web server board has the RS232C built-in, it can be connected to a personal computer by using this as the RS232C collector of the effector, and the effector functions as the Web server function. As a result, the data sent from the personal computer, via the RS232C, is input from the Web server board through the parallel port to the general-purpose port of the CPU of the effector, and the CPU of the effector is based on this data. Update the setting data. When sending data from the effector to a personal computer, the CPU of the effector sends the data to the Web server board via the general-purpose port,
Data received by the server board from the parallel port
Output to the RS232C connector on the Web server board,
RS23 of personal computer through cable from RS232C
The data is sent to the 2C connector and the personal computer receives the data. The personal computer displays the received data on a predetermined screen and displays the effector setting data all at once.

The timer function built in the one-chip CPU of the effector sets predetermined data from the CPU, so that the timer inputs an interrupt signal to the CPU and switches the CPU to the interrupt process at a fixed period. CPU
Synchronizes with this interrupt processing and operates an AD converter, a DA converter, or the like. In AD conversion, a tone color signal is converted from analog to digital. In the DA conversion, the sound effect data of the digital signal is converted into the analog sound effect signal.

Since the collector capable of inserting and removing the memory is provided outside the effector, the memory card can be attached and detached from the effector. This memory card is a semiconductor memory device in which the contents of data are ineffective.
Since EPROM or flash memory is built in, once data is written, it will not be erased even if the power is turned off. The CPU of the effector can directly write this memory data in the state where it is attached to the effector, or the CPU of the effector can read the data from the memory card and update or save the setting data of the effector.

When the effector displays on an external monitor, the general-purpose port of the CPU of the effector sends data to the monitor display circuit, and the monitor display circuit externally supplies an analog or digital monitor or monitor TV. A luminance signal, a horizontal synchronizing signal, and a vertical synchronizing signal are sent to display the effector setting data and the effector operating state on the monitor screen. The analog monitor is a composite input monitor television.
In this case, the horizontal synchronizing signal and the vertical synchronizing signal are mixed in the monitor display circuit to form a composite synchronizing signal. Also the brightness signal is R
It becomes black and white than the color of GB, and is mixed with the horizontal and vertical sync signals described above and included in the composite signal. In a digital monitor, each signal is directly input. As the analog monitor and the digital monitor, those of a personal computer can be used.

Since a one-chip CPU is used for effector display processing and tone color effect sound processing, one CPU is used.
Both processes can be performed with. A general-purpose port of the CPU is used for display, the general-purpose port is connected to a display circuit, and the output is displayed on a 7-segment LED display. Also for the sound effect processing of the tone color signal, the AD converter of the CPU is used to convert the signal into a digital signal, and the converted digital signal is subjected to predetermined processing so that the CPU produces a sound effect, for example, as shown in FIG. Performs various processing. As a result, the sound effect, which is the obtained data, is sent to the DA converter, becomes an analog signal, and is output to the outside from the microphone jack of the effector. Further, this analog signal is amplified by an amplifier incorporated in the effector, drives a speaker, and outputs a sound effect as a sound to the space.

Since the one-chip CPU is adopted as the effector, the display processing and the sound effect processing are as described above, but the rhythm sound can also be processed by the program of this one-chip CPU. Rhythm sound is CPU
The bead may be output regardless of whether the tone color signal of is returned to the sound effect.
Once every several times, a value corresponding to a tone color pulse of a predetermined magnitude is ORed to the data of the sound effect by calculation at a fixed ratio, and is output to this data DA converter.

Since the effector uses the one-chip CPU, the display processing and the processing of the sound effect of the tone color are as described above, but the DA converter for converting the sound effect and the DA is also the one-chip CPU. Since it is built-in, DA conversion can be performed by using this.

Further, if the operation switch is read out by using the general-purpose port of the one-chip CPU, data can be obtained in the CPU, and the operation switch can be processed by the one-chip CPU.

Further, one of the CPUs is a CPU called Hitachi SH-DSP. This is a new generation CPU that adds the complete functionality of a DSP to the CPU, and
It is also SP. Since this is used for the effector,
The display processing and the sound effect processing of the tone color are combined into one single chip C.
The PU can perform RS232C, AD conversion, and DSP processing. This IC has an AD converter, a DA converter, a clock circuit, a timer, a general-purpose port, a ROM, a flash memory, a sleep command, a power down function, and the like.

When the power of the effector is turned on, the CPU
Checks the setting data and, if there is an abnormality, sends the abnormal data to the display circuit. In the display circuit, the sent data is displayed by the 7-segment LED to inform the person of the abnormality.

Further, the battery voltage is converted into a numerical value by the AD converter of the CPU, and if it is not a predetermined value, the abnormality is similarly displayed. Further, the numerical value of the battery voltage is compared with the data table of the ROM, and the remaining usage time is also obtained from the data table, and this is sent to the display circuit to display a 7-segment LED display and the numerical value.
This allows a person to know the remaining time of the battery.

When a remote controller is provided outside the effector, the infrared remote controller is provided with a key switch, and each key switch has an effector volume increase (UP).
Down (DOWN), Distortion distortion (DIST) of a typical effect sound of an effector, and clean (C
LEAN) and a substantial power on / off switch for the power supply of the effector. When the key switch is pressed, a current flows through the light emitting element provided on the outer surface of the remote controller, and an infrared pulse is emitted from the light emitting element toward the effector. The emitted infrared rays enter the phototransistor of the receiving circuit of the effector, become a voltage signal, are amplified by the infrared light receiving circuit, and become a predetermined voltage signal. This is read from the general-purpose port of the CPU, the CPU performs predetermined processing, and the operation corresponding to the key on the remote controller
Performed at the effector. Conversely, when displaying data from the effector on the infrared remote controller, the CP of the effector
U sends a signal to an infrared light emitting circuit from a general-purpose port, and this light emitting circuit emits infrared rays toward a remote controller from a light emitting element attached to the outer surface portion of the effector. This infrared ray becomes a voltage pulse at the light receiving element on the outer surface of the remote controller, and becomes a predetermined voltage pulse at the light receiving circuit of the remote controller. The one-chip CPU of the remote controller reads this, processes predetermined data, and outputs the data to the display unit. This is displayed on the display unit with a 7-segment LED display, and the CPU is informed.

In the case of transmission to the effector by the wireless remote controller, transmission / reception between the effector and the remote controller of the electronic equipment by wireless is the same as in the case of the remote controller using infrared rays. The difference here is that when the light emitting circuit of the infrared remote controller is wireless, it becomes a transmitting circuit, and when the light receiving circuit of the infrared remote controller is wireless, it becomes a receiving circuit. Further, the light emitting element and the light receiving element of the infrared remote control function as one antenna in the case of wireless. When the effector is controlled by the wireless remote controller, when a key switch of the wireless remote controller is pressed, a signal corresponding to this key switch enters the CPU and the CPU sends predetermined pulse data to the transmitting circuit. In the transmitter circuit, C
Radio waves are emitted from the antenna based on the pulse data sent from the PU. The emitted radio wave is received by an antenna mounted in the effector and becomes a voltage.
The receiving circuit of the effector converts this into a voltage pulse and sends it to the CPU of the effector through the general-purpose port. The CPU reads the pulse train sent from the general-purpose port, restores it into predetermined data, and based on this data, selects a sound effect, increases / decreases the volume, and substantially turns the power on / off.

When transmitting data from the effector to the remote controller wirelessly, when displaying data on the wireless remote controller from the effector, the CPU of the effector sends a signal to the wireless transmission circuit from the general-purpose port, and the transmission circuit is connected to the external surface of the effector. It emits radio waves toward the antenna and remote control attached to the part. This radio wave becomes a voltage pulse at the antenna on the outer surface of the remote controller, and becomes a predetermined voltage pulse at the receiving circuit of the remote controller. The one-chip CPU of the remote controller reads this, processes predetermined data, and outputs the data to the display unit. This is displayed on the display unit with a 7-segment LED display, and the CPU is informed.

The same applies to the case where the effector is incorporated in the guitar.

Since the tone color signal is recorded in the memory in the effector, when the CPU reads it and outputs it as the tone color signal by the DA converter, this tone color signal is sent to the amplifier and is fed to the microphone jack. The tone color signal is sent to the outside. The accompaniment function works by playing a song along with this accompaniment.

A rhythm sound is obtained by the CPU in the effector counting the number of times for each fixed period interrupt and outputting an interrupt pulse at a predetermined rate of once every several times. This is converted into a tone color by a DA converter, amplified by an amplifier, and output to a microphone jack. If there is a speaker, the sound is output from the speaker.

If the amplifier has a built-in effector,
The effector is operated by the remote controller as in the case of remote controlling the effector by infrared rays or wirelessly. The timbre signal output from the effector is amplified by the amplifier, and becomes a sound by the speaker built in the amplifier. The effector operates the remote controller of the amplifier by operating the remote controller to instruct the size of the timbre, the change of the timbre, and the substantial ON / OFF of the power supply of the effector of the amplifier.

When the effector also presses the key switch, the CPU senses this, and when a pulse is periodically sent to the sounding element connected to the general-purpose port, the sounding element sounds and a confirmation sound for key operation is sounded.

The timbre signal input to the CPU 1 detects the presence or absence of a timbre signal in the timbre signal detection circuit 3 and detects this, and notifies the detection signal to the CPU 5 by interruption. The detection signal is also input to the general-purpose port 13. The CPU 5 may be a DSP. Further, the tone color signal from the microphone jack 5 is input to the external AD converter 17 and the AD converter 4 in the effector 1. Although there is a low-pass filter and an amplifier in front of the AD converter 4, they are omitted in the figure. As the AD converter 4, the one in which the SH-DSP of the CPU 5 is incorporated is used. The external AD converter 17 is
For example, MAX199C manufactured by Maxim can be used. CP

Further, the CPU 5 has a sleep instruction, and when this instruction is executed, the CPU 5 stops the execution of the program except for a part of the functions. This also reduces current consumption. To cancel this stop, the CPU 5 returns from the sleep state to the normal execution state by the interrupt signal of the tone color signal detection circuit 3 and starts execution again. CPU5

Although various types of EPROM 26 can be used, HN58C256 is adopted here. This is a dead memory that does not lose its contents even if the power is turned off once the data is written.

By the operation of the operation switches 53 and 54, the CPU 5 checks from the general-purpose port 13 what kind of sound effect the program should be selected by comparing with the setting data and the contents of the memory, and a predetermined value is determined.

The MIDI input circuit 36 uses the general-purpose port 13
Open collector output IC20 by PA0
0, input to SN7405, MI through resistor 201
It is output to the DI output terminal 5. When a current flows from the MIDI input terminal 4, the photocoupler 204 turns on and the phototransistor 206 of the photocoupler 204 turns on.
An input signal is sent to the general-purpose port 13PA1. When there is no signal at the MIDI input terminal 4, the phototocoupler 204 is in an off state, so the pull-up of the resistor 205 causes the input of the general-purpose port 13PA1 to be HIGH. This MIDI input and output signal is sent to the CPU by the general-purpose port 13PA1.

FIG. 7 shows a circuit diagram of the infrared light emitting circuits 20 and 40. When an infrared ray 75, which is one type of light, enters the light receiving elements 50 and 51 from the outside, the light receiving elements 50 and 51 are made of phototransistors, so that they are conductive and one emitter of the phototransistors 50 and 51 is connected to the ground. Therefore, the output terminal becomes LOW. When there is no infrared ray 75, the pull-up resistor 77 is HIGH. Since this signal has a small amplitude and cannot be read by the general-purpose port 13PE8, the operational amplifier 74 amplifies the voltage. LM3 for the operational amplifier 74

FIG. 2 shows a guitar 2 and an effector 1 of the present invention.
The external view of the effector built-in guitar which was integrated is shown. The guitar body 2 is provided with a string 74, and a pickup 73 is installed so as to face the string 74. When the string 74 vibrates,
This vibration changes the magnetic field of the pickup 73, and the pickup 73 generates a tone color signal that is the vibration of the string. This tone color signal is connected to the effector 1. Effector 1
Is an antenna 48, a 7-segment LED display 32, operation switches 53 and 54, a microphone jack 56, an external memory connector 30, an amplifier 15, a MIDI connector 58,
The RS232C connector 59, the USB connector 61, the sounding element 22, the light emitting element 52, the light receiving element 50, and the battery 21 are connected. A speaker 16 is connected to the amplifier 15, but in some cases, the speaker 16 may not be necessary. A wireless remote controller 24 and an infrared remote controller 23 are provided outside, and an antenna 47 and an infrared light emitting element 49 are provided.
The effector 1 of the guitar 2 is transmitted and received by the light receiving element 51 and the light receiving element 51, and is remotely controlled. Also, MIDI

FIG. 3 is an external view when the effector 1 is incorporated in an amplifier. Speaker 16 on the amplifier body 273

Is transmitted and received and is remotely controlled. Also,
It is connected to the personal computer 41 by connectors of MIDI 58, RS232C59, USB 61 and cables 42-46. The structure is the same as that of incorporating it into the guitar, only the arrangement of each part is different, and the function is the same. The guitar body 2, the strings 74, and the pickup 7
3 is not in the amplifier.

The effector 1 includes the above circuit blocks.
Operates as follows. Tone signal detection circuit 3 of FIG.
Detects a silent state, the general-purpose port 13PG0 of the CPU 5 sends a signal to the power-supply current off circuit 27 to turn off the 7-segment LED display 32 in order to reduce the power supply current of the effector 1. When PG0 becomes HIGH,
The voltage of the display circuit 31 drops and the entire 7 segment LE
The D display 32 becomes dark. (Fig. 5). Also, unlike this, when the / B1 terminal of the MC14511B of the IC 115 of the display circuit 31 is LOW at the port PG1, the IC 115 turns off the 7-segment LED display 32. (Fig. 1
3). As another method, as a method of reducing the current consumption of the CPU 5 itself, a sleep command of the CPU 5 is executed.

When the CPU5 SH7065 is SBYCR
When the sleep instruction is executed when the SBY bit of the register is 0, the CPU 5 shifts from the program execution state to the sleep mode. To cancel the sleep mode, send an interrupt signal PH0 to the CPU 5 to restart the program and start execution. In case of SH7065, interrupt signal P
H0 is displayed on the interrupt terminal under the name IRQ0. This interrupt signal is the tone color signal detection circuit 3 described above.
The pulse of Q of MC14538 of is used. In addition to this, the CPU 5 also has a standby mode. Another method is to reduce the execution speed of the program of the CPU 5. This means that if the CPU5 is SH7065, the FRQCR register in the CPU5 has FR0-FR7.
You can change the clock frequency by writing the desired value to the bit. As a result, when data is set in the target bit, one-half, one-third, and one-fourth of the maximum clock frequency is obtained, and the clock frequency is reduced. When the operating speed of the CMOS CPU 5 decreases, the current consumption also decreases in proportion to this. In the above, the tone color signal detection circuit 3
Is used to detect silence, but not limited to this
If the data of the D converter 4 does not change near 0 for a long time, it may be determined as a silent state. Operation switch 5
When 3 and 54 are not pressed, it means that the type of sound effect of the effector 1 is not selected and the volume is not changed, and the 7-segment LED display 32 consumes a maximum of about 30 milliamperes when lit. However, if this is reduced or eliminated, it occupies a considerable amount of the current consumption of the effector 1 of about 100 milliamperes, so that the current consumption is effectively reduced. Therefore, whether the operation switches 53 and 54 are pressed or not is detected by the PI0 and PI1 of the general-purpose port 13. (Fig. 6). If both PI0 and PI1 remain HIGH for a long time, it is determined that the buttons 53 and 54 are not operated, and C
The PU 5 turns off or turns off the 7-segment LED display 32. When PG0 is set to HIGH from the general-purpose port 13, the 7-segment LED display 32 turns off the light. When PG1 is set to LOW, 7-segment LED display 3
2 goes off.

In addition, there is a case where the precious current of the battery 21 is wastefully consumed due to an erroneous operation during transportation or the like, the effector 1 and the amplifier 15 are activated, and unnecessary sound is emitted from the speaker 16. In such a case, when the sound is being output from the speaker 16 for a long time, including during performance, it may be possible to display the 7-segment LED display 32 and turn off or turn off the light. Therefore, the data sent to the DA converter 9
The CPU 5 monitors, and when the volume continues to be large for too long, the 7-segment LED display 32 is turned off or turned off. Therefore, if you operate PG0 or PG1,
The consumption of the battery 21 can be reduced.

The indication of the remaining usage time of the battery 21 is the battery 2
The power supply voltage of 1 is connected to the AD converter 4. C
When the PU 5 is SH7065, since there are eight AD converters 4, one of them is used for conversion of the power supply voltage of the battery 21. The CPU 5 obtains the AD-converted value, and the ROM 1
In 0, the remaining time is calculated as a numerical value based on a data table in which the characteristics of the battery are written in advance. The data has the following structure.

The 3 bytes of the numerical value of the AD converter 4, abnormal or normal, and remaining usage time are configured as one set. Then, according to the numerical value 0-255 of the AD converter 4, 256
The street is set in the ROM 10. The CPU 5 first searches for 3 bytes corresponding to the numerical value of the AD converter 4, and obtains an intermediate or abnormal flag as a numerical value as a numerical value. If it is normal, next, the remaining usage time of the numerical value of the next byte is obtained, sent to the display circuit 31, the general-purpose port 13PB0-4 is used, and the 7-segment LED display 3
It is displayed when the sound effect is switched to 2 or when the power is turned on. PB4 is for latching. (Figure 13)

If it is determined that there is an abnormality, the 7-segment LED display 32 displays the abnormality with predetermined characters or numbers. When the power is turned on, the CPU 5 programs the battery 21 to check first.

The effector 1 has a USB connector 61 and R
S232C connectors 59 and 60 are provided on the outer surface of the case. The USB connector 61 or the RS232C connectors 59 and 60 are connected to the personal computer 41 via the cables 43 and 45. For that purpose, CPU5 is USB
The circuit 35 (FIG. 19) and the RS232C circuit 37 are connected. When the CPU 5 is SH7605, the RS232C uses the serial communication port SCI, which is used. RS232C circuit 37
Is the IC139 MAX232 of the part of FIG.
And use the same circuit. In this case, the serial communication port SCI of the CPU 5 has the same function as S7600.

When the effector 1 transmits / receives the setting data to / from the personal computer 41, the CPU 5 obtains the setting data from the EEPROM 26 of the setting memory, and the CPU 5 receives the setting data.
The data is sent in a predetermined procedure by the built-in SCI. Serial data is input to the RS232C circuit 37 and RS2
The 32C circuit 37 converts the signal voltage from 0 to 5V to -12V + 12V. Transmission speed and format are S
If desired data is set in the CI register, various speeds and formats can be selected. On the personal computer 41, Windows 95 is operated, and access is made to Start-Program-Communication-Hyper Terminal to operate Hyper Terminal. Hyper Terminal The signal is displayed on the signal screen from the RS232C of the personal computer 41, and this information is displayed and recorded inside the personal computer 41. By saving this record as a file, the setting data of the effector 1 can be saved. About 1000 characters can be displayed on the screen display so that the setting data can be viewed.

The USB circuit 35 can also perform the same operation as RS232C. (FIG. 19). In this case, CPU5
Sends the setting data to the USB circuit 35, and this is US
It is output from the B connector 39 and is connected to the USB connector of the personal computer 41 through the cable 45. PC 4
1, RS232C and USB connector are standard, and both hardware and software are built in, so the same as S232C of hyper terminal can be performed. Here, the personal computer 41 is used, but other handheld computers, word processors, and electronic devices such as game machines can perform the same function as long as it has the same function, and the present invention is not limited to the personal computer 41.

When sending data from the personal computer 41 to the effector 1 and operating the effector 1, in the above-mentioned state,
The transmission function of the per terminal of the personal computer 41 is used.
In advance, the data is filed in the personal computer 41 according to the setting data, or the saved setting data file sent from the effector 1 is sent by the hyper terminal. As a result, RS232 from the PC 41
Or from the USB through the cables 43 and 45, the RS232C connector 59 of the effector 1 or the USB connector 6
Data is sent to 1. In the case of RS232C,
RS232 signal voltage to -12V + 12V to 0-5V
It is converted by the C circuit 37 and sent to the SCI built in the CPU 5.
The received data is stored in the SCI register, which is read by the CPU 5, and this data is set in the setting memory EEPR.
Write to OM26. The same applies when using USB, US
Data enters from the B connector 61 into the USB circuit 39, and I
Data is recorded in C143 and USBN9602. The CPU 5 reads this and writes it in the setting memory 26 in the same manner as the RS232C. The CPU 5 performs a predetermined operation based on the written data.

The effector 1 and the personal computer 41 are MID
Also when connecting with the I connector 58, it is the same as the above except that the circuit used is different. The MIDI circuit 36 is as shown in FIG. The MIDI circuit 36 is a general-purpose port 1 of the CPU 5.
Use 3PA0 and PA1. When data is input or output by the MIDI circuit 36 and the CPU 5 sets the bit 0 or 1 to the general-purpose port 13PA0, this is output from the MIDI connector No. 5. Also MIDI
When there is data from the connector No. 4, this data is input to HIGH, the port PA1. PA0 and PA1
Both are controlled by a program in the CPU 5, and various operations can be performed. Therefore, operations other than the MIDI standard can be performed by limiting the use state. In the present invention, both the personal computer 41 and the effector 1 can be used by setting a predetermined program so as to perform the communication format outside the MIDI standard. This example is as described above. Although the data set above is stored in the EEPROM 26, the RA is temporarily stored.
It may be M7. The general-purpose port 13PA3 is directly connected to the sounding element and generates a confirmation sound when a key is operated.

In communication between the effector 1 and the personal computer 41 using TCP / IP, the CPU 5 uses the TCP / IP circuit 3
4 sends a predetermined command to the IC of the TCP / IP circuit 34
137 also has a TCP / IP procedure inside, and C
The PU 5 can leave the main procedure of TCP / IP to the IC 137. The CPU 5 can be operated in the same manner as the serial communication IC i8251. So C
When the PU 5 transmits / receives the setting data to / from the personal computer, the setting data is sent from the setting memory 26 to the IC 137, the CPU 5 reads the internal register of the IC 137, confirms the operation, and confirms the setting data 26.

Similarly, data of the effector 1 can be transmitted / received if it is a device such as a game machine or a word processor that can be connected to the Internet. When data is transmitted to the effector 1 by the personal computer 41, the procedure similar to that of the RS232C or USB is used, and the setting data can be sent from the personal computer 41 to execute the operation of the effector 1.

C8-PC15 is output, data output PC16 is write output, PC17 is read input, and each signal is distributed. On the other hand, the parallel port 136 uses QA0-QA7 as data outputs and QA0-QA7 as data inputs. Allocate so that QC0 is a write input and QC1 is a read output. This distribution is not limited to this, and can be changed at any time.

In this way, the PC8-PC15 are connected to the CPU5.

When data is set in 0-7 and QC1 is set to HIGH, the data is input to PC0 to PC7 of the general-purpose port 13 and read by the CPU 5. The Web server 29 includes a local CPU 40 and a flash memory ROM.
There is a flash memory ROM 14 in which a program is created and compiled in the C language of LINUX.
It is stored in 0. In this way, data can be processed by the CPU 5 of the effector 1 and the personal computer 41.
RS232C, USB, TCP using server
Similarly to / IP and MIDI, the setting data of the effector 1 can be written in the setting memory and the contents of the data can be displayed on the screen of the personal computer 41 in the same manner.

When SH7065 is adopted for the CPU 5, this IC 5 has a timer 6, an AD converter 4, and a DA converter 9
When this is used, the timer 6 has a timer counter function and can generate a fixed cycle interrupt as shown in FIG. CPU5, in line with this,
The AD converter 4 or the DA converter 9 is activated. CPU
Since the address bus, the data bus, and the control signal of 5 are connected to the external memory connector 30, from the outside,
When the memory 191 is set in the connector 30, the CPU 5 of the effector can receive programs from the external memory 191 other than the programs programmed in the ROM 10 of the effector 1. This is written in the setting memory 26 as setting data. It is also possible to read the setting data from the setting memory 26, write it in the external memory 191, and save it. The external memory 191 can use an EEPROM or a flash memory and can be rewritten. In this embodiment, the external memory 19
Although RAM and EEPROM are used as the first example, the present invention is not limited to this, and CD-ROM, CD-R, DVD-ROM, D
An optical storage medium such as VD-RW may be used. As a result, even when the setting data is read, the same operation as that of the external memory 191 is performed. In this case, the external memory connector 30 becomes the drive unit 30 of each optical storage medium. The drive unit 30 uses, for example, MP9060A manufactured by Ricoh in the ATAPI interface. In addition, the EEPRO of the setting memory 26
Setting data is recorded in M. To this, a processing program (sound effect processing software 8 and rhythm sound processing software 19) of a tone color sound effect is read from the drive unit 30,
There is also a method in which the CPU 5 executes a sound effect processing program.

The effector 1 has a monitor display circuit 21, which can be used to display the contents of the setting data and the operating state on the external monitor 33. This is as shown in FIG. When it is desired to display on the monitor 33, the CPU 5 causes the built-in timer 6 to generate a fixed-cycle interrupt, and sends the screen information from the PD0-D7 of the general-purpose port 13 to the IC123 74HC166 in accordance with this pulse. Further, horizontal and vertical synchronizing signals are also output from the general-purpose port 13. PD8 is used horizontally and PD9 is used vertically.

By using the AD converter 4, the DA converter 9, and the CPU 5 having the general-purpose port 13 therein, for example, SH7065, the processing of timbre effect sounds and rhythm sounds, the reading of operation switches, and the display of a 7-segment LED are performed. Not only display processing of the device 32, but also AD conversion 4 and DA conversion 9
Also, it can be substantially performed with one IC5. SH-DSP S
The H7065 also has DSP hardware integrated, including the DSP completely, and the CPU instruction and DSP.
It is possible to mix and use the instructions of.

Conventionally, the DSP and the second CPU 180 may be replaced with one CPU 5.
The present invention also utilizes this.

The remote controller 23, 24 is used to remotely control the effector 1, or the effector 1
When sending information to the remote controllers 23 and 24, the remote controller 23 is an infrared ray, and the remote controller 24 remotely controls the effector 1 in substantially the same manner as when the remote controller 24 is a wireless type. From the infrared remote control 23, key switch 63-
When 67 is pressed, the specified pulse train is sent to the CPU of the remote controller 23.
It is output from the general-purpose port 62. The infrared remote controller or the wireless remote controller has the same function, and thus only one remote controller is required and exclusive use is made. Therefore, PJ0-PJ in FIGS.
8 is common. Infrared remote control 2 for explanation
3 and the wireless remote controller 24 are shown at the same time, either one may be used in actual use. When the key switch 63-67 is pressed from the infrared remote controller 23 and a predetermined pulse train is input, the CPU 5 obtains a pulse train signal coming to the light receiving element 50 of the effector 1 from the PE 8 of the general-purpose board. (Figure 7)

With respect to this data, the CPU 5 processes the serial into a parallel signal, checks whether it is up, down, distortion, clean, or power on / off, and executes the processing. From the clean up to the clean, the operation of the circuit is the same, only the processing program for processing the sound effect of the data sent to the DA converter 9 by software is different.
For power on / off, the power supply current off circuit 27 and the 7-segment LED display circuit 31 are operated. Further, the instruction of the CPU 5 executes a sleep instruction or a standby instruction, and the clock circuit 11 further reduces the execution speed of the CPU 5 to bring the same state as when the power is turned off. The power supply current off circuit 27 can be performed by outputting PG0 of the general-purpose port 13.

In the case of accompaniment by the effector 1 including the case of being incorporated in the guitar 2, it is an example of accompaniment by rhythm sound in the procedure of FIG. The periodic interrupt is as shown in FIG. If the CPU 5 reads the setting data from the setting memory 26 and the rhythm sound is generated, the CPU 5 causes the program to generate the rhythm sound in the procedure of FIG. Rhythm sound is D
The A converter 9 synthesizes the tone color sound effect and outputs it. In order to synthesize the rhythm sound into the sound effect of the timbre, the CPU 5 processes the data with 080H by the OR command and 0EF by the AND command.
When H is performed, the rhythm sounds are 1XXXXXXX and 0XXXX.
Like XXX, the MSB of data repeats 0 and 1,
This becomes the rhythm sound. The part of the X character written here is the part of the sound effect of the timbre and is always output. As a result, the rhythm sound and the sound effect of the timbre are combined by the program, and by sending this to the DA converter 9, both sounds can be output. In addition to this, when the sounding element 22 is turned on / off by the PA3 of the general-purpose port 13, a beeping sound is produced, which can be used as a substitute for a simple rhythm sound such as a metronome.

The CPU 5 obtains the data of the tone color signal from the AD converter 4 including the effector 1 built into the guitar 2 and not the rhythm sound, and outputs the data to the RAM 7 or EEPR.
It is temporarily stored in the OM 26. When the accompaniment is required, the CPU 5 sends it to the RAM 7 or the EEPR as required.
When the data is read from the OM 26, the sound effect sound of the tone color is ORed by the operation, and the result is sent to the DA converter 9, an accompaniment other than the sound effect can be synthesized and output.

When the effector 1 is incorporated in the amplifier 273, an external view is shown in FIG. The electromagnetic wave prevention sheet plate 22 is attached to the person side. The contents of this amplifier are almost the same as those in the block diagram of FIG. Also,
This is the same as when the speaker 16 is incorporated in the effector 1 incorporated in the guitar, except for the strings 74, the pickup 73, the guitar body 2, and the microphone jack 56. In the case of an amplifier, the parts relating to the effector 1 are the same. The monitor connector 96 is shown in FIGS. 2 and 3, but it is not shown. In the case of an amplifier, the timbre signal of the pickup 73 of the guitar 2 is input to the microphone jack 75. On the amplifier, the guitar 2 from the external guitar 2 to the microphone jack 75
, The string 74 and the pickup 7 are input.
3 and the guitar body 2 are unnecessary. Although the effector 1 is incorporated in the guitar 2 in FIG. 2, the speaker 1 is not always necessary.
6 is not necessary. The amplifier requires the speaker 16, but some amplifiers do not have a speaker.

Since the present invention is configured as described above, it has the following effects. An electromagnetic wave prevention sheet cancels electromagnetic waves that are harmful to humans with a magnetic field that generates eddy currents, or a magnetic material electromagnetic wave prevention sheet plate prevents electromagnetic waves from reaching people by blocking magnetism and blocking electric fields. . Further, a method of sending a signal for reducing current consumption to a power supply current off circuit or a display circuit, and / or setting a CPU clock register by a program to decelerate the CPU clock, thereby reducing the current consumption of the CPU itself. The current consumption of the effector can be reduced by the method of reducing the current consumption.

The data of the AD converter is monitored, and when there is no signal, the CPU detects it by a program, the power supply current off circuit is set to HIGH at the general-purpose port PG0, the power supply of the display circuit is lowered, and the 7-segment LED display is performed. The current consumption of the container can be reduced. Also, when a signal is sent to the IC of the display circuit immediately after turning off the display, the 7-segment LED display is turned off and the current consumption is reduced, so that the current consumption of the effector can be reduced.

The tone color signal detection circuit detects the silent state of the tone color signal and notifies the CPU of this signal by an interrupt signal. The CPU program sets the power supply current off circuit to HIGH at the general-purpose port PG0 and turns on the power supply of the display circuit. It is possible to lower the current consumption of the 7-segment LED display, and if the signal is sent to the IC of the display circuit immediately after turning off the display, the 7-segment LED display will turn off and the current consumption will decrease, so the effector The current consumption can be reduced.

Furthermore, in order to reduce the current consumption of the CPU, if the CPU executes the sleep instruction, the current consumption can be further reduced and the current consumption of the effector can be reduced. Further, by setting the CPU clock register, the CPU clock can be decelerated, and as a result, the current consumption of the CPU is reduced and the current consumption of the effector can be reduced.

Further, the IC MC14 of the tone color signal detection circuit
When the output of 538 elapses after a certain period of time, the timing when a certain period of time in the silent state has elapsed is obtained. This is the CPU
Then, by sending a signal to the power supply current off circuit,
The segment LED display can be dimmed and the display circuit I
7-segment LE when CMC4511 is instructed to turn off
Since the D display is turned off and the current consumption is reduced, the current consumption of the effector can be reduced.

When the operation switch is not pressed by the CPU, the general-purpose port is checked. If the operation switch is not pressed, the power supply current off circuit is controlled to turn off the 7-segment LED display, or the display circuit Control IC, 7
Since the segment LED display can be turned off,
The current consumption is reduced and the current consumption of the effector is reduced. Further, since the CPU monitors the data of the AD converter, it is possible to know that the speaker is in the sounding state for a long time. In this case as well, the same function as when the operation switch is not pressed and the display is made. Dimmed or off,
The current consumption of the effector can be reduced.

When the CPU checks the operation switch from the general-purpose port and detects that the operation switch is pressed, the function of the power supply current off circuit is canceled, the original brightness of the 7-segment LED display is restored, and when the operation of the operation switch is completed, The 7-segment LED display can be turned on by operating the power supply current off circuit. In addition, the IC of the display circuit is not turned off but turned off.
Since it can be controlled, it can be set according to the case.

Since the voltage of the battery is connected to the AD converter, the CPU can obtain the battery voltage data, and the ROM has the data table, so that the remaining usage time of the battery can be estimated and the remaining battery life can be estimated. Use time 7 segment LE
By sending it to the D display, it can be displayed so as to inform the person of the remaining usage time of the battery.

At this time, if there is an abnormality in the battery, for example, when the remaining usage time is 0, and if there is an abnormality, the CPU can know the abnormality from the data table described above. It can be displayed to inform people of abnormalities.

USB, RS232C, or
There is a MIDI connection circuit and connector, and you can send and receive data by connecting to the connector of the personal computer with a cable.
For handheld computers other than personal computers, electronic devices such as word processors and game consoles, USB, RS23
If there is a 2C or MIDI connector, or if these are standardly supported by the operation system, they can be connected to an effector like a personal computer and various operations can be performed, and data can be transmitted and received.

Since effector setting data can be transmitted / received from / to the screen of this type of device including a personal computer, various kinds of information can be displayed on the screen at one time. Easy to check with eyes.

From the personal computer side to the effector, USB,
The RS232C or MIDI connection circuit and the connector can be connected with a cable to send data to the effector, so the effector can change the sound effect based on this,
Operations such as changing the volume can be performed from the PC side. The power can be turned off substantially.

Further, the data sent from the personal computer can be stored in the EEPROM or RAM by writing it in the setting memory EEPROM or RAM in the effector.

USB data from the effector to the personal computer
Alternatively, when the data is transmitted through the RS232C or MIDI connector and connection circuit, the data received by the Windows 95 hyper terminal of the personal computer is stored in the personal computer. This can be saved as a file on a floppy disk of a personal computer, so effector data such as setting data can be saved on a floppy disk.

The CPU has a MIDI circuit and a MIDI connector as an effector, and a special format is built into the effector by software and is transmitted / received by a personal computer, whereby the personal computer and the effector are connected by a method other than the MIDI standard. In addition, data can be transmitted and received as in the case of USB.

Since a TCP / IP circuit is provided in the effector, it is possible to use RS / IP with an electronic device such as a personal computer, a handheld computer, a word processor, or a game machine by TCP / IP.
Since it can be connected with a cable through the 232C connector,
Since Windows 95 has a built-in TCP / IP standard in the personal computer, it has TCP / IP control as a standard, and like the Internet, data can be sent and received between the personal computer and the effector using TCP / IP.

Since a Web server board is provided in the effector and can be transmitted / received to / from the CPU through a general-purpose port, by connecting the RS232C of the Web server board to a personal computer with a cable, Windows 9 of the personal computer is connected.
5, data can be transmitted and received with the effector.

When a one-chip CPU is used as the CPU,
For example, using SH7065 SH-DSP, AD
Converter, DA converter, clock circuit, timer 6
Functions such as a flash memory, a RAM, and a ROM can be substantially realized by a single IC. As a result, when the timer 6 generates a fixed-cycle interrupt and the AD converter and the DA converter are operated in accordance with this, a compact board can be obtained. Furthermore, the consumption current is externally AD
Compared to the case where the converter or the DA converter is provided, the current consumption of the effector can be reduced. As a result, the effector using the battery can extend the life of the battery. Other one-chip CPUs can also obtain the same effect as long as they have the above-described built-in functions, and the one-chip CPU or the one-chip DSP can be selected at a suitable time.

Since the monitor display circuit is provided in the effector,
The setting data of the effector can be displayed collectively on the external monitor. Since the contents of the effector setting data can be seen on the screen at once, the contents of the design data can be easily grasped. The effector has an external memory and a connector, the memory is set here, the CPU writes the setting data to this, and the effector can easily write and save the setting data in the storage medium of the external memory.
The setting data memory can be inserted and removed. The optical storage medium is a CD-ROM, a DVD-ROM, a C
When the D-R is used, the program for processing the effect sound of each tone color can be read into the EEPROM or RAM and the effect sound of the effector can be set. In addition, it is possible to read a tone color sound effect processing program (sound effect processing software, rhythm sound processing software) from the drive unit and execute the sound effect processing program by the CPU. Can be input to and output from the optical storage medium. Furthermore, it becomes easy to confirm, operate, store, and replace the effector setting data. Further, if the effector is connected to the personal computer or the electronic device only by the MIDI standard MIDI, the operation is improved, and the operation can be greatly improved.

Since the one-chip CPU SH7065 is used, the effector can display the operating state by only one CPU using the general-purpose port, and can process the sound effect of the tone color and / or The rhythm sound generation process can be substantially performed by one CPU.
This has the effect of making the effector substrate compact, improving reliability, and reducing costs.

Further, since the one-chip CPU has an AD converter and a DA converter, these can be processed by one CPU.

Furthermore, the operation switch is also a one-chip CPU
Since it can be read by the general-purpose port of, this processing can also be processed by one CPU.

SH of the SH-DSP even with a one-chip CPU
The 7065 has a built-in DSP, CPU instructions and DSP
Since the command of can be completely described, the sound effect processing of the tone color,
The display processing can be performed faster, and the second CPU is not required unlike the conventional display and key operation.
The effector can be substantially composed of PU. The board is also compact.

Infrared rays as a slave unit outside the effector,
Alternatively, since a remote controller for an electronic device of wireless or an electronic device is provided, the CPU can input / output data by a general-purpose port by a light emitting circuit or a light receiving circuit of an effector, or a transmitting circuit or a receiving circuit by infrared rays or wireless. So with effectors,
Data can be transmitted to and from these electronic devices. This data controls the effector remotely. In addition, the operating state of the effector can be confirmed also in the electronic device.

This electronic device may be in the shape of a remote controller, and may not be in the shape of a remote controller. In the figure, the remote controller shape is used for explanation.

From the remote controller, the volume of the sound volume, the change of the tone effect sound, and the power on / off of the effector can be remotely controlled to the effector by infrared rays or wirelessly.

In the integrated type in which the guitar and the effector are built-in, the effector can output the rhythm sound to the DA converter and the program which also generates the rhythm sound by the fixed period interrupt to the CPU. Then, when a speaker is connected, it can be output as a sound. If there is no speaker, an electric signal can be output as a tone signal sound from the microphone jack.

Further, also in the sounding element, the CPU uses the above-mentioned fixed-cycle interrupt from the general-purpose port and the CPU processes it so that a pulse is sent at a fixed time interval and the sounding element can generate a sound. Can be used as a sound. This rhythm sound is also one of the accompaniment functions.

When the amplifier or the guitar and the effector are integrated, the CPU can AD-convert the timbre signal into the RAM or the EEROM and record it.
By reading from RAM or EEPROM and sending to a DA converter, the tone color signal can be reproduced as an accompaniment when needed.
Can be accompanied by a guitar or amplifier.

Furthermore, since the effector can generate a rhythm sound, it can also be used as an accompaniment to the rhythm sound.

When the effector is integrated with the amplifier,
The contents of the CPU can be notified to the CPU of the pulse train of the remote controller through a general-purpose port through the light emitting element and the light receiving element of the effector, and the light emitting circuit and the light receiving circuit of the effector by an infrared or wireless remote controller. This gives C
The PU can perform various operations such as the volume of the sound effect of the tone color, the change of the sound effect, and the power on / off operation.

When operating the operation switch buttons, the CPU
The general-purpose port is read, and in response to this, the sound-producing element is driven in a pulse form from the general-purpose port, so that a confirmation sound can be generated from the sound-producing element when the button is operated. A pulse may be sent to a DA converter other than the sounding element. In this case, the program sends a pulse to the DA converter, synthesizes it in the same manner as the rhythm sound, and outputs it. In this case, a confirmation sound signal may be output from the microphone jack or may be sounded from a speaker.

By integrating an effector with an amplifier or a guitar, it is convenient to carry and convenient.
