08-05-2019
14
above in the process of step S203, and executes the process of step S201 again.
[0063]
Therefore, according to the in-vehicle acoustic device 100, when the operator adjusts the sound
quality or volume to any sound quality or volume, the operator temporarily changes all of the
sound quality or volume to a predetermined sound quality or volume at the same time. The
volume can be adjusted to any sound quality or volume.
[0064]
In the present embodiment, when the sound quality is adjusted by the sound quality adjustment
unit, the in-vehicle audio device 100 can not adjust the volume by the volume adjustment unit,
and when the volume is adjusted by the volume adjustment unit. Although the sound quality can
not be adjusted by the sound quality adjustment means, according to the present invention, the
vehicle-mounted audio device 100 may have another configuration as long as it can adjust the
sound quality and the volume.

quality and volume by simultaneously pressing a plurality of two or more switches.
The more switches pressed at the same time, the less the possibility that the operator
erroneously sets the sound quality and volume to the predetermined sound quality and volume
can be reduced.
Further, according to the present invention, the operator may set the sound quality and the
volume to predetermined sound quality and volume by pressing one switch.
When the operator sets the sound quality and volume to predetermined sound quality and
volume by pressing one switch, the operation can be facilitated.

audio device can be controlled by simultaneously pressing any of a plurality of switches of the
08-05-2019
16
existing on-vehicle audio device to obtain the sound quality and volume, the predetermined
sound quality and volume. By changing the setting to “on”, it is possible to make the existing
vehicle-mounted audio device into the vehicle-mounted audio device capable of setting the sound
quality and the volume to a predetermined sound quality and volume without newly providing a
switch.
[0069]
Further, in the present embodiment, the operator can set the sound quality and the volume to the
predetermined sound quality and volume by simultaneously pressing the two switches of the
sound quality adjustment switch 110 and the time setting switch 160. According to the present
invention, the operator can set the sound quality and the volume to the predetermined sound
quality and volume by continuously pressing the two switches of the sound quality adjustment
switch 110 and the time setting switch 160 simultaneously for a predetermined time. Good.
If the operator sets the sound quality and volume to a predetermined sound quality and volume
by continuously pressing the two switches of the sound quality adjustment switch 110 and the
time setting switch 160 simultaneously for a predetermined time, the operator may erroneously
Even if the two switches, the sound quality adjustment switch 110 and the time setting switch
160, are simultaneously pressed, the sound quality and the volume can be prevented from being
set to the predetermined sound quality and volume as long as it is shorter than a predetermined
time. .
Of course, according to the present invention, by setting the sound quality and the volume to the
predetermined sound quality and volume by continuously pressing the switch for a
predetermined time, the above-described one switch is pressed. In some cases, the sound quality
and volume may be set to predetermined sound quality and volume, and the sound quality and
volume may be set to predetermined sound quality and volume by simultaneously pressing a
plurality of two or more switches. It can apply.
[0070]
Here, according to the present invention, when the operator keeps pressing the switch for a
predetermined time to set the sound quality and the volume to the predetermined sound quality
and the volume, the in-vehicle acoustic device performs the switch for a predetermined time. By
08-05-2019
17
continuing pressing for a shorter time, the sound quality and volume may be set to any desired
function other than setting the predetermined sound quality and volume. For example, when the
operator keeps pressing the predetermined three switches for a predetermined time to set the
sound quality and the volume to the predetermined sound quality and volume, the operator may
set the predetermined three switches for a predetermined time. By continuing to press for a
shorter time, for example, the vehicle 200 (see FIG. 1). The sound quality and volume such as the
action of extinguishing the sound output from a speaker (not shown) mounted on the) or the
action of playing back, rewinding, fast-forwarding, or stopping the recording medium recording
the sound, etc. An operation other than setting to a predetermined sound quality and volume
may be performed.
[0071]
Therefore, according to the present invention, the internal software of the existing in-vehicle
audio device can be made to have the sound quality and the volume at the predetermined sound
quality and volume by keeping the existing in-vehicle audio device pressed for a predetermined
time for any switch. By changing the setting to the setting, it is possible to make the existing
vehicle-mounted audio device into the vehicle-mounted audio device capable of setting the sound
quality and the volume to predetermined sound quality and volume without providing a new
switch.
[0072]
Further, in the present embodiment, the operator can set the sound quality and the volume to
predetermined sound quality and volume, but according to the present invention, the operator
does not change the sound volume but only the sound quality. , And may be set to a
predetermined sound quality.
[0073]
According to the present invention, if the sound quality and the volume can be adjusted, the onvehicle audio-visual apparatus is also included in the on-vehicle audio apparatus.
[0074]
As described above, according to the present invention, the operator can simultaneously change
all the sound quality or the volume to the predetermined sound quality or the volume by the
simple operation of pressing the predetermined switch. Can.
