Abstract

PURPOSE:To attain the change of the value of the voice output in an information processor by changing the tilt of a display screen. CONSTITUTION:A tilt detector detects the tilt of a display unit, and a gain switch box 11 switches an attenuator 12 based on the detected tilt of the display unit. The gain of each attenuator 12 is previously set in response to the desired sound volume. Thus it is possible to easily and temporarily change the value of the voice output just by changing the tilt of a display screen.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to information processing apparatuses such as personal computers and word processors, and more particularly to information processing apparatuses having an audio output device.

0002

[Prior Art] In conventional devices, when changing the level of audio output, it is common to operate the device's audio output adjustment knob or key. Some models allow you to change the level of audio output by operating knobs or keys according to instructions.

[0003] As described above, in conventional devices, the level of the audio output is set to a desired level and a constant level.

0004

[Problems to be Solved by the Invention] The above-mentioned prior art does not take into consideration the operability when it is necessary to suddenly change the loudness level of the audio output. The problem was that there was no.

An object of the present invention is to provide a mechanism for adjusting the loudness level of audio output that is easy to operate.

[0006]

[Means for Solving the Problem] The above object is achieved by a mechanism in which each preset level of audio output is selected in accordance with the degree of inclination of a display screen that can be rotated and stored. achieved.

[0007]

[Operation] The display screen can be rotated to change its tilt. When the magnitude of the slope changes, the magnitude of the audio output changes. Therefore, the size of the audio output can be changed by adjusting the tilt of the display screen.

[0008]

[Embodiment] An embodiment of the present invention will be explained below with reference to FIG.

The display screen 1 is fixed to a display unit 2, and is attached to the main body 4 of the personal computer by an arm 3 which also serves as a rotating shaft. The user operates the personal computer by operating the keyboard 5, etc., and the audio output is radiated into the air as sound from the speaker 6. The volume of the audio output at that time, that is, the volume of the sound, can be set to a desired volume by operating the volume controller 7.

When the "screen mode" is selected with the mode changeover switch 8, the tilt detector 9 detects the angle at which the display unit 2 is opened, and outputs audio at a preset level depending on the size of the angle. Do this. The method of switching the audio output at this time will be explained with reference to FIG. In the same figure, the audio signal amplified by the middle stage amplifier 10 passes through the mode changeover switch 8 and then passes through the gain changeover box 1.
It reaches 1. The gain switching box 11 automatically switches between four stages in response to the tilt of the display unit 2 detected by the tilt detector 9. Corresponding attenuator 1
The gain of 2 is a preset value. The audio signal that has passed through the attenuator 12 is amplified again by the final stage amplifier 13. The final stage amplifier 13 is provided with a volume adjuster 7, and the volume can be adjusted in common for the signals that have passed through any of the four attenuators. Also, when the mode selector switch 8 is turned off and the volume of the audio output is made constant regardless of the degree of tilt of the display unit 2, the volume controller 7 provided in the final stage amplifier 13 can be used to adjust the volume of the audio output. The height can be adjusted.

In the above example, the magnitude of the audio output is changed stepwise, but the detection signal of the tilt detector 9 is treated as a continuous amount, and the gain switching box 11 and attenuator 12 are integrated to continuously change the gain. Even if you change it, you will get the same result.

0012

[Effects of the Invention] According to the present invention, the size of the audio output can be changed simply by changing the tilt of the display screen.
Moreover, the volume of the audio output can be changed temporarily.

Claims (1)

[Claims] Claim 1: In an information processing device having a display screen that can be rotated to open and close and an output device that outputs audio, the level of the volume of the output audio is determined by the angle of the rotating display screen. A personal computer characterized in that a corresponding predetermined value is set.
