Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to audio devices.

[0002]

[Prior art]

 Human hearing has the characteristic that when the volume is low, high and low range sounds are harder to hear than middle range sounds. To compensate for this, high and low ranges are adjusted according to the volume (hereinafter VR). Audio devices with a loudness function that boosts the range are becoming popular. The loudness function is usually linked to the main VR to generate a loudness characteristic corresponding to the VR position, and the loudness characteristic curve is determined at the design stage of the equipment.

[0003]

[Problems to be solved by the device]

 However, such conventional loudness cannot meet the user's preference, so it is necessary to operate the loudness and bass treble at the same time, or to turn off the loudness and adjust only the bass treble to suit the preference. was there. The present invention aims to solve the above-mentioned problems of the prior art.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a storage device for storing a high-frequency and low-frequency boost amount of a loudness effect and an operation key of the audio device in an audio device equipped with a loudness circuit and a switch device for operating the loudness. When the loudness circuit is operated by the setting means for setting the high-frequency and low-frequency boost amounts in the storage means and the switch means, the high-frequency and low-frequency boost amounts are called from the storage means, and the loudness circuit is used. And a control means for generating a loudness characteristic.

[0005]

[Action]

 When the high-frequency and low-frequency boost amounts are stored in the storage means by the setting means and the loudness circuit is operated, the high-frequency and low-frequency boost amounts are called from the storage means and the loudness circuit is caused to generate the loudness characteristic. As a result, the loudness effect can be realized according to the taste of the user.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The microcomputer 1 includes an operation unit 2 and a display device 3. A memory 10 is provided inside the microcomputer 1 so as to store the boost amount of the loudness function. The operation unit 2 includes an up key 20, a down key 21, a mode button 22, and a loudness switch 23. The loudness switch 23 is a key for setting the loudness mode. By operating this key, a loudness characteristic according to a predetermined boost amount according to the VR value stored in the memory 10 of the microcomputer 1 can be obtained. It is designed to be used. The loudness adjustment mode is set by pressing the mode button 22 for a predetermined time, and the boost amount adjusted by pressing the mode button 22 for a predetermined time is stored in the memory 10.

A signal from the tuner 6, the tape deck 7 or the external source 8 is switched by the switching circuit 9 and input to the amplifier 15 via the loudness circuit / main VR 4 and the bus / treble circuit 5 and amplified. The speaker 16 is configured so that it can be converted into voice later.

When the loudness switch 23 is operated, the microcomputer 1 sends to the bass treble circuit 5 a boost amount of data according to the VR position stored in the memory 10, and a predetermined loudness characteristic is obtained according to the data. It is configured to generate. Further, when the mode button 22 is pressed, the amount of boost is stored in the memory 10 in response to the user's operation of the up key 20 and the down key 21.

The solid line in FIG. 2 shows the loudness characteristic set in the loudness circuit / main VR 4 at the design stage, and each broken line is based on the boost amount stored in the memory 10 which can be arbitrarily set by the user. The loudness characteristic is shown. FIG. 3 shows the relationship between the VR position and the loudness boost amount. In this embodiment, the VR position is from 0 to 33, and the loudness works when the VR position is less than 27. The boost amount from 1 to 13 is +6, and the boost amount from 14 to 26 is +4. The microcomputer 1 is configured to check a change in the VR position and, when the position is changed, control the bass treble circuit 5 so as to change the boost amount accordingly.

A boost amount setting operation will be described with reference to FIG. When the mode button 22 is pressed for 2 seconds (step 40), the microcomputer 1 checks whether or not the loudness switch 23 is off, and if it is off, the loudness is turned on (step 42). When the user operates the up key 20 and the down key 21 to adjust the boost amount in the low frequency range (step 43), the microcomputer 1 detects that the mode button 22 has been pressed for 2 seconds or more. (Steps 44 and 45), the adjusted boost amount is stored in the low frequency area of the memory 10 (step 46). When 10 seconds or more have passed without pressing the mode button 22 (step 47), the operation is ended.

Next, when the user operates the up key 20 and the down key 21 to adjust the boost amount in the high frequency range (step 48), the microcomputer 1 confirms that the mode button 22 has been pressed for 2 seconds or more. It is detected (steps 49 and 50), and the adjusted boost amount is stored in the high frequency area of the memory 10 (step 51). When 10 seconds or more have passed without pressing the mode button 22 (step 52), the operation is ended.

A loudness execution operation will be described with reference to FIG. When the loudness switch 23 is turned on (step 60), the microcomputer 1 calls the boost amount of the high range and the low range from the memory 10 (step 61), and confirms that the VR position is less than 27 (step 61). In step 62), the loudness circuit of the loudness circuit / main VR 4 is operated in accordance with the boost amount to generate the loudness characteristic stored in the memory 10 (step 63). Then, the VR position is checked to see if it has passed through the boost amount switching position shown in FIG. 3 (step 64). If it has passed, it is checked whether the VR position is in the down direction or the up direction (step 65), and the boost amount is increased or decreased correspondingly (steps 66, 67). Then, the loudness is turned off and the operation ends (step 68).

According to the configuration described above, the user can set a desired loudness characteristic in advance, so that a desired sound can be easily obtained. Further, since the boost amount is also changed according to the change in the VR position, it is possible to always obtain the best loudness effect.
