Abstract

A display device includes, a display component, a speaker, a setting component, and a controller. The speaker outputs a first signal having guidance information pertaining to an operation performed on the display device or a status of the display device and a second signal having audio information pertaining to content displayed on the display component. The setting component sets a volume setting value of the display device to performs volume setting. The controller sets output levels of the first signal and the second signal to values corresponding to the volume setting value, respectively, such that the output level of the first signal is greater than or equal to the output level of the second signal, and the output level of the first signal is greater than zero when the volume setting value is set to zero.

Claims

1. A display device comprising:

a display component;

a speaker that outputs a first signal having guidance information pertaining to an operation performed on the display device or a status of the display device and a second signal having audio information pertaining to content displayed on the display component;

a setting component that sets a volume setting value of the display device to performs volume setting;

a table in which output levels of the first signal and the second signal are respectively associated with volume setting values such that the output level of the first signal is greater than or equal to the output level of the second signal, and the output level of the first signal is greater than zero when the volume setting value is set to zero; and

a controller that automatically sets the output levels of the first signal and the second signal to values corresponding to the volume setting value, respectively, based on the table such that the output level of the first signal is greater than or equal to the output level of the second signal, and the output level of the first signal is greater than zero when the volume setting value is set to zero,

a change amount in the output level of the first signal due to a specific change in the volume setting value being a value less than or equal to a change amount in the output level of the second signal due to the specific change in the volume setting value.

2. The display device according to claim 1, wherein

difference between the output level of the first signal and the output level of the second signal at a specific volume setting value is greater than difference between the output level of the first signal and the output level of the second signal at a volume setting value that is greater than the specific volume setting value.

3. The display device according to claim 1, wherein

the output level of the first signal is a value that falls within a specific range.

4. The display device according to claim 3, wherein

a settable volume range of the setting component is set to a range in which the output level of the first signal is greater than or equal to the output level of the second signal.

5. The display device according to claim 1, wherein

the table includes a first table in which specific output levels of the first signal are associated with volume setting values, and a second table in which output levels different from the specific output levels of the first signal are associated with the volume setting values, and

the controller controls the output level of the first signal based on either the first table or the second table.

6. The display device according to claim 5, wherein

the controller selects either the first table or the second table according to the guidance information of the first signal.

7. The display device according to claim 1, wherein

the controller performs control to change both the output levels of the first signal and the second signal along with a change in the volume setting value.

8. The display device according to claim 1, wherein

the speaker outputs the first signal indicative of an audio volume setting in response the volume setting being performed.

9. The display device according to claim 1, wherein

the speaker outputs the first signal indicative of a channel number setting in response a channel number being changed.

10. The display device according to claim 1, wherein

the speaker outputs the first signal indicative of an input selection setting in response an input selection being changed.

11. A display device comprising:

a display component;

a speaker that outputs a first signal having guidance information pertaining to an operation performed on the display device or a status of the display device and a second signal having audio information pertaining to content displayed on the display component;

a setting component that sets a volume setting value of the display device to performs volume setting;

a table in which output levels of the first signal and the second signal are respectively associated with volume setting values such that the output level of the first signal is greater than or equal to the output level of the second signal, and the output level of the first signal is greater than zero when the volume setting value is set to zero; and

a controller that automatically sets the output levels of the first signal and the second signal to values corresponding to the volume setting value, respectively, based on the table such that the output level of the first signal is greater than or equal to the output level of the second signal, and the output level of the first signal is greater than zero when the volume setting value is set to zero,

a change rate in the output level of the first signal relative to the volume setting value being less than or equal to a change rate in the output level of the second signal relative to the volume setting value.

12. The display device according to claim 11, wherein
