Abstract

PURPOSE:To simplify structure by issuing a hardware control instruction to a sound volume/sound quality controller when an operation key being a regular input at the time of depressing only a control operation key so as to adjust a sound volume and sound quality while the control operation key being the special input by means of combination with the other key is depressed. CONSTITUTION:When the operation keys 34-37 are independently depressed, they move a cursor in a screen vertically and horizontally by one character. When the operation key 34 is depressed while the operation key 32 is depressed, sound volume is raised by 5dB, for example. Sound volume is lowered by the combination of the operation keys 32 and 35. Sound quality is raised by the combination of the operation keys 32 and 36. Control for deteriorating the sound quality is executed by the combination of the operation keys 32 and 37. Control for raising a musical interval by one octave when the operation key 34 is depressed in a state where the operation keys 32 and 33 are depressed and for dropping the musical interval by one octave when the operation key 35 is depressed in a state where the operation keys 32 and 33 are depressed, for example. Thus, structure is simplified.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a processing method for adjusting the volume and sound quality of an information processing device by pressing a combination of keys on a general-purpose keyboard. It is.

[Conventional technology]

Hitachi Creative Workstation 2050 0F I S/DESK-EV (2) Grammar Operation Manual (1,987) pp. 161 to 163 as a method to adjust volume and sound quality without using mechanical parts such as volume. As described in the page, there is a method in which a window is displayed on the screen and setting values can be changed using keyboard input or mouse input in an interactive format using a menu. However, since a window is displayed and control is transferred to the window, there is a problem in that the work currently being carried out is temporarily interrupted.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration changes in volume and sound quality while the work is continuing, and there is a problem in that the work currently being carried out must be temporarily interrupted in order to change the volume and sound quality.

The purpose of the present invention is to eliminate the trouble of displaying a window to change the volume and sound quality and transferring input control to that window, and to prevent interruption of work, and to further improve operability. With the goal.

[Means for solving Section M]

In order to achieve the above purpose, on a general-purpose keyboard, while pressing a control operation key that produces a special input when combined with other operation keys, we also press an operation key that becomes a normal input when pressed alone. When pressed, a hardware control command is issued to the volume and sound quality adjustment device, making it possible to adjust the volume and sound quality.

[Effect]

Hardware control of the volume and sound quality adjustment device can be performed by pressing a control operation key that becomes a special input when combined with other operation keys, and then pressing an operation key that becomes a normal input when pressed alone. The 3-hydraulic type issues commands and adjusts the volume and sound quality by pressing multiple operation keys at the same time.

Since it is possible to adjust the sound quality, there are no errors caused by pressing the wrong button.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. Fig. 2 is a schematic perspective view showing the external appearance of an information processing apparatus to which the present invention is applied. Input device 13. It is composed of a speaker I4.

FIG. 1 is a schematic diagram showing the internal structure of the central processing unit (CPU) 21. Operation keys 22.23°24,
Volume and sound quality adjustment device 25. It is composed of a speaker 26. When the operation key 22 is pressed alone, it is processed as a normal keyboard input. When the operation key 23 is pressed, the operation key 22 is pressed at the same time. Alternatively, if the operation key 23 and the operation key 24 are both pressed and the operation key 22 is pressed at the same time, a hardware control command is issued to adjust the volume and sound quality to operate the volume and sound quality adjustment device 25. The volume and sound quality generated from the speaker 26 are changed.

FIG. 3 shows a general-purpose input device to which the present invention is applied, and the input device 31. Operation key 32.33°34,3
Consists of 5.36.37. When the operation keys 34, 35, 35, and 37 are pressed individually, they move the cursor on the screen one character up, down, left, and right, and the operation keys 32.
33 is a control operation key for adjusting the volume and sound quality in combination with operation keys 34, 35, 36, and 37. When operation key 34 is pressed while pressing operation key 32, the volume can be increased by, for example, 5 dB. Issues a command to operate the volume and sound quality adjustment device. Further, the operation keys 32 and 35 are used to lower the volume, the operation keys 32 and 36 are used to increase the sound quality, and the operation keys 32 and 37 are used to reduce the sound quality.
If you press the operation key 34 while both 33 and 33 are pressed,
For example, operation keys 32 and 33 raise the pitch by one octave.
If the operation key 35 is pressed while both are pressed, control such as lowering the pitch by one octave is performed, for example.

FIG. 4 shows an example of a processing method for changing the volume. At step 400, it is first checked whether the operation key 34 is pressed. If the operation key 34 is pressed, step 410 is executed and it is checked whether the operation key 32 is pressed. If operation keys 34 and 32 are pressed at the same time, step 420 is executed and the volume is increased. If only operation keys 3 and 1 are pressed, step 430 is executed and the cursor on the screen is moved up by one character. Operation key 34
is pressed, and if not, step 440 is executed. In step 440, it is checked whether the operation key 35 is pressed, and if it is pressed, step 450 is executed and the operation key 3 is pressed.
Check if 2 is pressed. Operation key 35.32
If both are pressed at the same time, step 460 is executed and the volume is decreased. If only the operation key 35 is pressed, step 470 is executed and the cursor on the screen is moved down by one character.

Note that the operation keys 32 and 33 do not need to be specially prepared for adjusting the volume and sound quality; for example, a normal shift key for switching between uppercase and lowercase letters can be used as an operation key for control.

〔Effect of the invention〕

As explained above, the present invention eliminates conventional mechanical parts such as a volume knob and simplifies the structure of an information processing device, thereby improving reliability.

Furthermore, by omitting operations such as displaying a window and transferring input control, the volume and sound quality can be changed without interrupting work, which has the effect of improving operability.
