In such a way, even if an audio part of an AV apparatus is in a silenced state that the sound volume is attenuated temporarily by the silencing means 4, the sound volume can be increased and decreased without emitting a sound from a loudspeaker 6 by a sound volume increase/decrease command from a key input mans 9 or a remote control signal receiving means 8, and the sound volume of its time point can be confirmed as a standard of a sound volume control state by the display means 10, therefore, the AV apparatus can be operated without giving trouble by noise.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of adjusting volume in an AV device equipped with a volume adjusting means and a muffling means.

[Conventional technology]

In A'V equipment such as audio amplifiers and televisions, the audio section is equipped with a volume adjustment means for increasing or decreasing the volume and a muffling means for temporarily attenuating the volume, and is in a muted state where the volume is temporarily attenuated. At this time, even if a volume increase/decrease command is given to the control means from the key input means or the remote control signal receiving means, the volume cannot be changed by the volume adjustment means, or the volume is changed after canceling the muted state.

[Problem to be solved by the invention]

In the above-mentioned AV equipment, after the volume adjustment means mutes the sound at a high volume, the key input means or the remote control signal receiving means gives a volume increase/decrease command to the control means to listen at a low volume next time. However, once the mute state is canceled and the sound is emitted at a high volume, the volume is gradually decreased, which causes a temporary noise problem in households with young children and the elderly.

The present invention provides means for increasing or decreasing the volume using the volume adjusting means even when the sound is muted by the muffling means.

[Means to solve the problem]

The control means for controlling the volume adjusting means and the muffling means provides a volume reduction control signal to the volume adjusting means in response to a volume reduction command from the key input means or the remote control signal receiving means, and is in a muted state. At this time, the muted state is displayed, and a display signal corresponding to the loudness of the audio signal output by the volume adjusting means is output to the display means, and the volume when the muted state is released is displayed as a guide. .

[For production]

When the control means recognizes the control command output from the key input means or the remote control signal receiving means as a volume reduction command, it gradually decreases the volume setting value of the signal controlling the volume adjustment means, and adjusts the volume setting value to the decreased volume setting value. outputs a lid control signal corresponding to the volume adjustment means to the volume adjustment means.

Next, it is determined whether or not the sound is muted in the sound deadening means, and if the sound is muted, the volume setting value at that time is outputted to the display means, and the display means indicates that the sound is muted. At the same time, an indication of the current volume control status is also displayed.

Subsequently, it is determined whether the volume reduction command from the key input means or the remote control signal receiving means continues, and if the command continues, the control operation such as decreasing the volume setting value is repeated; If the volume reduction command from the key input means or the remote control signal receiving means has been completed, the volume reduction operation in response to the volume reduction command is completed.

〔Example〕

FIG. 3 is a block diagram of an audio section of an AV device for implementing the present invention.

In the figure, la to IC are a plurality of audio signal inputs in the AV equipment, 2 is input switching means for selecting one of the input signals, 3 is supplied with the audio signal output from the input switching means 2, and A volume adjusting means for increasing or decreasing the volume of the audio signal; 4 a silencing means for temporarily attenuating the audio signal output from the volume adjusting means 3; 5 amplifying and outputting the audio signal output from the silencing means 4; The speaker 6 is driven by the output from the output means.

8 is a remote control signal receiving means for receiving and decoding a remote control signal for controlling the operation of the AV equipment; 9 is a key input means for controlling the operation of the AV equipment; 7 is an output of the remote control signal receiving means and/or the key input means. A control means reads a control command signal to control the operation of the input switching means, the volume adjustment means, and the silencing means based on the control command signal; This is a display means for displaying the operating status.

Key input means 9 in the audio section of the AV equipment
Alternatively, based on a volume increase or volume decrease command output from the remote control signal receiving means 8, the control means 7 sends a control signal for volume increase or sound fit decrease to the volume adjustment means 3 to adjust the volume.

The control means 7 also receives a mute or non-mute command output from the key input means 9 or the remote control signal receiving means 8.
sends a control signal for silencing or non-silencing to the silencing means 4, and temporarily attenuates or cancels the sound emitted from the speaker 6.

The volume adjustment method of the present invention in an AV device equipped with the audio section described above will be explained with reference to the flowchart shown in FIG.

When the control means 7 recognizes the volume reduction command output from the key input means 9 or the remote control signal reception means 8, it starts executing the volume reduction according to a predetermined procedure.

First, the volume setting value, which is the standard of the volume control signal output from the control means 7 to the volume adjustment means 3, is gradually decreased;
A volume control signal corresponding to the reduced volume setting value is output to the volume adjustment means 3, and the magnitude of the audio signal output from the volume adjustment means is gradually decreased.

Next, it is determined whether or not a mute control signal is being outputted to the mute means 4, and if the mute state is in which a mute control signal is being output, the mute control signal corresponds to the volume setting value together with a mute state display signal. A volume display signal is sent to the display means 10, and the display means 10 displays a message indicating that the sound is muted and an indication of the volume control state.

In determining the output of the mute control signal, in the non-mute state in which a non-mute control signal is output, a volume display signal corresponding to the volume setting value is sent to the display means 10 along with a display signal of the non-mute state. , the display means 10 displays an indication that the sound is not muted, as well as an indication of the volume control state.

In the flowchart of FIG. 1, as an example for a color television, the volume control status is displayed in red when the sound is muted and in green when it is not muted.

Figure 2 shows a specific display example on the TV screen, in which 10 dots are superimposed on the TV screen and displayed at the bottom of the screen, and the current state when the volume setting value at maximum volume is lO. The approximate value of the ratio of the volume setting value is displayed as a number of square marks or a bar graph from the left side.

After displaying an indication of the volume control state in the display means, it is determined whether the volume reduction command outputted from the key input means 9 or the remote control signal receiving means 8 to the control means 7 continues to be output, and the volume is decreased. If the command continues to be output, the procedure after gradually reducing the volume setting value is repeated, and if the volume reduction command is not continuously output, the current display on the display means is continuously displayed for a certain period of time, for example, 5 seconds, and then Clears the volume display and ends the volume reduction operation in response to the volume reduction command.

At the end of the volume reduction operation in response to the above-mentioned volume reduction command, after erasing the volume display, it is determined whether the sound is muted, and if it is in the mute state, the mute state is automatically canceled and then the volume reduction operation is performed in response to the volume reduction command. You can also terminate the process to simplify the operation.

The above is an explanation when the volume is decreased, but even when the volume is increased, the same operation as when the volume is decreased can be achieved by changing the procedure of gradually decreasing the volume setting value to gradually increasing the volume setting value in the procedure for decreasing the volume. Can be done.

〔Effect of the invention〕

As described above, even if the audio section of the AV equipment is in the muted state, in which the volume is temporarily attenuated by the muting means, the sound from the speaker can be heard by a volume increase/decrease command from the key input means or the remote control signal receiving means. In other words, the volume can be increased or decreased even when the sound is muted, and the current volume can be checked on the display as a guide to the volume control status. It becomes possible to operate AV equipment without causing trouble to other people.
