Abstract

PURPOSE:To set tone quality at a place where the tone is to be listened and to display the set value in an easy-to-see state by displaying the set value on a cathode-ray tube which constitutes video equipment while varying the tone quality by a wireless remote controller. CONSTITUTION:A remote control signal sent by a remote control transmitter 12 is inputted to a remote control receiver remote control receiver 11 and sent to a controller 13. The controller 13 generates two control signals. One is a control signal for controlling a graphic equalizer and this control signal is sent to a graphic equalizer circuit 15 to control the tone control of a sound input signal 17. The other signal is a control signal for controlling a character and graphic signal generator 14 and this control signal is sent to a character and graphic signal generator 14, which is so controlled as to display the set state of the graphic equalizer. Then, a character and character and graphic signal is sent to the cathode-ray tube 7, where the setting state of the graphic equalizer is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wireless sound quality control device for a composite device of audio equipment and video equipment.

Conventional technology In recent years, audio/visual equipment, which is a combination of audio equipment and video equipment, is required to have high quality sound.
A sound quality adjustment means called a graphic equalizer, which allows the user to set the desired sound quality for each frequency, has come into use.

Most of the sound quality control methods for these audio/visual devices are controlled by operating variable resistors or touch panels attached to the device itself, and some also allow sound quality control by remote control. However, the setting values were displayed using small LEDs.

An example of a conventional sound quality control device will be described below with reference to the drawings.

FIG. 3 shows the positional relationship in sound quality settings for conventional sound field settings. In FIG. 3, 1 and 2 are audio e-visual equipment. 3 is a speaker system. Reference numeral 4 denotes a setting panel section of the graphic equalizer and a display section for displaying its setting values (hereinafter abbreviated as graphic equalizer setting display section).

6 is for the person who wants a good sound field (hereinafter referred to as listener),
Indicates the location where you want to hear the sound (hereinafter abbreviated as listening position). 6 indicates a position for operation (hereinafter abbreviated as setting position).

The operating method for setting the graphic equalizer in the audio/visual equipment configured as described above will be explained below.

Now, when the listener wants to set the optimal sound quality for listening position 6, he or she can move to setting position 6-1 and predict the optimal sound quality for listening position 5 and operate the GRAICO setting display section 4, or listen to position 6. Settings were made using the remote control at the location.

Problems to be Solved by the Invention However, with the above configuration, (a) when the remote control transmitter is not used, even though it is desired to set the sound quality at listening position 6, the setting must be made at setting position 6; Therefore, in order to obtain the expected sound quality at the listening position 6, it is necessary to repeat the operation of setting at the setting position 6 and checking at the listening position 6. However, since the listener always moves to the setting position 6 at this time, the setting value can be easily confirmed even if the display is small.

(b) When using a remote control transmitter, the settings can be made at the scanning position 6, so there is no need to go back and forth to the location many times to set the settings mentioned in (a) above.
It does not have the problem mentioned in b), but the setting value is displayed as L.
If the value is as small as ED, there is a problem in that it is difficult to confirm the set value.

The present invention solves the above-mentioned conventional problems, and provides a sound quality control device that allows easy setting of sound quality at the listening position and also allows easy confirmation of display of the set value. .

Means for Solving the Problems In order to solve the above problems, the wireless sound quality control device of the present invention has a remote control transmitter, a remote control receiver, and an on-screen function for displaying a single character on a cathode ray tube. This system is equipped with video equipment, and when a listener sets the sound quality using a remote control from a distance from the equipment, the set value is displayed large and brightly on-screen.

Effects of the present invention With the above-described configuration, the sound quality can be set with a remote control, so the listener can control the sound quality while staying at the listening position, and the setting values can be displayed on the oniscreen on the cathode ray tube. The large and bright display makes it possible to easily check the setting values. Practical example A wireless sound quality control device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the operating state of a wireless sound quality t7jju device according to an embodiment of the present invention. FIG. 2 shows a block diagram in an embodiment of the present invention.

In FIGS. 1 and 2, 7 is a cathode ray tube.

8 is an on-screen screen showing the setting values of the graphicalizer displayed on the cathode ray tube 7.

9 is a speaker system. 10 is audio-visual equipment. 11 is a remote control receiver that receives remote control signals. 12 is a remote control transmitter that transmits a remote control signal. Reference numeral 13 denotes a control device which decodes the contents of the remote control signal and generates a control signal according to the contents.

14 is a character/figure signal generator. 15 is a graphic equalizer circuit. 16 is an audio amplifier. 17
is the audio input signal.

Next, the operation of the remote control transmitter 12 at the position of the sensing position 5 in FIG. 1 will be explained. A remote control signal emitted from the remote control transmitter 12 is input to a remote control receiver 11 attached to the audiovisual equipment 10 and transmitted to the controller 13. The controller 13 generates the following two control signals in response to the remote control signal. One is a control signal υ for controlling the graphic equalizer. This control signal is transmitted to the graphic equalizer circuit 15, and the sound quality of the audio input signal 17 is controlled by this signal. The other is a control signal for controlling the character/graphic signal generator 14;
4 and controls the character/graphic signal generator 14 to display the setting status of the graphic equalizer. The audio signal controlled by the graphic equalizer circuit 16 is amplified by the audio amplifier 16 and output as an audio signal from the speaker system 9, so that the listener can enjoy the sound. On the other hand, the character/figure signal generator 14 transmits a character/figure signal indicating the setting status of the graphic equalizer to the cathode ray tube 7, and the setting status of the graphic equalizer is displayed on the cathode ray tube 7 as shown at 8 in FIG. Ru.

Although the embodiment of FIG. 1 has been described using a television receiver using a CRT as an example, it can of course be applied to a liquid crystal TV or any video equipment that displays a large screen.

Effects of the Invention As described above, according to the present invention, it is possible for the listener to set the sound quality wherever he or she wants to listen, and also to display the set value in an easy-to-see manner. Since it utilizes the functions that conventional television receivers have, it can be constructed at low cost.
