DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle audio apparatus having operation buttons for changing, adjusting, and setting a plurality of reproduction functions.

[0002]

2. Description of the Related Art Conventionally, as this kind of in-vehicle audio apparatus, there is an apparatus having a configuration shown in FIG. In the conventional in-vehicle audio device, by operating the operation button 42 provided on the front portion of the device main body 41 or by operating the operation button 44 provided on the wireless remote controller 43, it is possible to change various functions, Adjustments and settings were made.

[0003]

However, the above-mentioned conventional in-vehicle audio device has a small operation button and poor operability. That is, in recent in-vehicle audio devices, the number of functions has been increased and the number of operation buttons for changing and adjusting settings has also increased, and especially in-vehicle audio devices need to be housed in a limited space. For,
There has been a problem that the external dimensions of the operation button are reduced, and as a result, it is difficult for the operator to operate.

In order to reduce the number of operation buttons, the same button may be operated a plurality of times, or the buttons may be operated continuously for a certain period of time. Complicated operation. For example, 15
When adjusting the graphic equalizer of a band, once for selecting the frequency to be adjusted (15 times for all 15 bands), at least one for adjusting the amplification amount.
The operation is performed 15 times (in the case of 15 bands), and a complicated and time-consuming operation is required. In particular, the operability is poor for the operator driving the vehicle.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide an excellent in-vehicle audio device capable of easily and reliably performing operations for changing, adjusting and setting various functions. With the goal.

[0006]

In order to solve the above-mentioned problems, the present invention is characterized in that adjustment and setting of functions are performed by a single operation button, and the number of operation buttons is small and simple. The operation enables reliable operation.

[0007] Further, the operation button can be constituted by a first switch operated by a pressing operation and a second switch operated by a rotating operation.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is a vehicle audio apparatus having a plurality of playback functions, wherein the adjustment and setting of the playback functions are performed by a single operation button. The setting can be changed and adjusted by a reliable operation.

According to a second aspect of the present invention, the operation button comprises a first switch operated by a pressing operation and a second switch operated by a rotating operation. Enable.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. Embodiment 1 FIG. 1 shows a configuration of an image display device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a switch, a push switch 2 serving as a first switch operated by a pressing operation is provided at a center portion thereof, and a second switch for generating a pulse signal according to a rotation operation is provided at an outer peripheral portion thereof. A rotation switch 3 is provided as a switch. Reference numeral 4 denotes a system control microcomputer.
The entire device is controlled based on the operation described above. Reference numeral 5 denotes a reproducing apparatus, which includes a plurality of reproducing units such as a radio receiver, a CD player, a cassette player, and an MD player. Reference numeral 6 denotes a control circuit which controls a reproduction signal from the reproduction device 5 based on a command from the system control microcomputer 4. Reference numeral 7 denotes an amplifier, which amplifies an audio signal and outputs the amplified audio signal to speakers 8 and 9. Reference numeral 10 denotes a display unit, which displays a selected reproducing apparatus, a setting state or an adjustment state of various functions such as a frequency characteristic or a volume.

Next, the operation of the on-vehicle audio device according to the present embodiment having the above configuration will be described.

In FIG. 1, by rotating the rotary switch 3, a pulse proportional to the rotation angle is generated. The number of pulses is counted by the system control microcomputer 4, and a control state based on the count value is displayed on the display unit 10. When the push button 2 is pressed when the desired count value is reached, a series of operations is completed.

Here, the system control microcomputer 4 issues a control command corresponding to the count value to the reproducing device 5 and the control circuit 6.
Output to The playback device 5 outputs a playback signal from the playback unit selected by the control command from the system control microcomputer 4 to the control circuit 6. The control circuit 6 controls a reproduction signal based on a control command from the system control microcomputer 4 and outputs the reproduced signal to the amplifier 7. As a result, a reproduced signal corresponding to the operation result of the switch 1 is amplified by the amplifier 7 and
9 and reproduced.

FIGS. 2 and 3 are display diagrams showing the adjustment mode of the graphic equalizer. FIG. 2A shows an initial state, in which a display 21 is turned on and set at the center value of a certain frequency band of a 5-band graphic equalizer. When the rotary switch 3 is turned to the right by one click, the display 21 moves to the next right frequency band by one step (FIG. 2B). Further, when the rotary switch 3 is turned rightward by two clicks, the display 21 moves to the frequency band on the right by two steps (FIG. 2 (c)). Here, when the push switch 2 is pressed, the frequency band in which the display 21 is lit is set to a state where adjustment is possible (FIG. 2D).

Further, as shown in FIG. 3A, when the rotary switch 3 is turned right by one click, the display 21 moves to a position where the frequency band is amplified by one step. Conversely, turning the display counterclockwise two clicks moves the display 21 to a position where it is attenuated by two levels (FIG. 3B). When the push switch 2 is pressed in this state, a series of operations in the graphic equalizer adjustment mode is completed, and the graphic equalizer characteristics are set to the state shown in FIG. During the adjustment, the display 21 can be clearly displayed as a blinking state to indicate that the adjustment is being performed. When the display 21 is set, the display 21 can be turned on.

As described above, in the above embodiment, the function change and adjustment are performed by rotating the rotary switch 3, and the function change and adjustment are set by pressing the push switch 2. Because you can
The setting can be changed and adjusted by a simple operation with a small number of operation buttons.

In the description of the operation of the above embodiment, the adjustment mode of the frequency characteristic of the graphic equalizer has been described. In addition, the selection mode of the reproduction unit such as the radio receiver and the CD player in the reproduction apparatus, When setting and adjusting various functions such as volume setting or volume balance, the setting change or adjustment and the setting of the adjustment are the same as those in the above-described embodiment only by the rotating operation of the rotary switch 3 and the pressing operation of the push switch 2. It is possible.

[0018]

As described above, according to the present invention, the function can be adjusted and set by the single operation button operated by the pressing operation and the rotating operation, and the conventional complicated and time-consuming operation can be performed by the operator. Therefore, there is an effect that the setting can be changed and adjusted by a simple and reliable operation without compelling.
