DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio apparatus for displaying identification information of a broadcasting station being received or identification information relating to a recording medium being played.

[0002]

2. Description of the Related Art As a conventional audio apparatus, a receiving means including a tuner and the like, a CD player as a playing means for playing a recording medium such as a CD, an audio correcting means such as an equalizer and a DSP for applying an audio correction to an audio signal, and LCD
Some have display means such as.

In such an audio apparatus, the title of a broadcasting station being received, the title of a CD being played, and the sound field (hall, live house, etc.) for which sound is being corrected can be displayed. It is possible to recognize the setting state regarding.

[0004]

However, in the above-mentioned conventional audio apparatus, since the setting information irrelevant during the current operation mode is not displayed, it is not possible to recognize, for example, the initial setting state when the power is turned on. There was a problem.

[0005] In particular, in the case of an in-vehicle audio device, there is also a problem that a large screen display unit cannot be provided due to the restriction of the entire panel, so that much setting information cannot be displayed.

The present invention solves such a conventional problem, and displays a large amount of setting information of operation modes other than the current operation mode on display means having a limited number of display characters. It is an object of the present invention to provide an excellent audio device capable of performing such operations.

[0007]

In order to achieve the above object, each setting information for setting each operation state of the receiving means, the playing means and the sound correcting means is displayed on the display means for a predetermined time in a predetermined order. And setting information referencing means for causing the setting information to be referred to.

[0008]

Therefore, according to the present invention, a large amount of setting information, which is irrelevant to the current operation mode, can be displayed on the display means having a limited number of display characters.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of an audio apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a receiving unit (receiving means), and a tuner unit (TUNER) 1
a and a PLL circuit unit 1b having a function of tuning a received radio wave. The receiving unit 1 not only has a tuning function of selecting a designated station from radio waves such as FM broadcasting and AM broadcasting from each broadcasting station, but also seeks a station that can be continuously received by the PLL circuit unit 1b. An operation and an auto-store function of storing frequency data of a station being received in response to a predetermined command, and a function of calling the station of the stored frequency data with a single touch by pressing a preset key described later. I have.

Reference numeral 2 denotes a CD player, which plays one CD disk (hereinafter simply referred to as a disk). 3 is C
It is a D-auto changer (hereinafter simply referred to as a CD changer), and can perform while accommodating a magazine to which a plurality of discs (for example, six) can be mounted. The CD player 2 and the CD changer 3, which are playing means for playing these recording media, continuously play songs (also referred to as tracks) recorded on a CD, as well as special performances such as random performances and program performances. Is possible. Further, it has a search (SEARCH) function for searching for a specified disc or track based on disc content information (hereinafter referred to as TOC) recorded on each disc.

Reference numeral 4 denotes a CPU as control means for controlling the audio device. Reference numeral 5 denotes an operation unit for inputting a command to the CPU 4 in response to a user operation, and includes various keys for inputting an operation mode of the apparatus.
Reference numeral 6 denotes an LCD display (display means) having a character display of 14 segments, 8 digits, a numerical display of 7 segments, 4 digits, and an indicator for displaying each operation mode state.

Reference numeral 7 denotes a ROM which stores programs to be executed by the CPU 4 and necessary initial value data. The initial value data is, for example, broadcast information obtained from the receiving unit 1 so that the user names a radio wave (frequency) from a broadcast station that provides only a specific genre such as news, traffic information, and music. Or the genre name for naming a disc in which genres such as classical, jazz, and rock are recorded in the music information obtained from the CD player 2 and the CD changer 3. As described later, this genre name is typed (TYP
E). This type can be displayed on the display unit 6 according to a predetermined operation.

The display unit 6 has an eight-digit part for displaying an eight-digit character (character) and a part for displaying numerical data. For example, in the part displaying a character, in the tuner mode, "NH
The titles of broadcasting stations such as “K FM”, “FM TOKYO”, and “NAC 5” are displayed, and in the CD mode, titles of CD album names and track names (song names) are displayed. In the part to be displayed,
The frequency of the broadcasting station and the track number of the disc are displayed.

Although not shown in FIG. 1, the audio device is connected to a DSP for performing sound correction on a received audio signal or an audio signal obtained by reproducing a disk.

Further, the operation unit 5 is provided with a review (REVIEW) key for referring to and displaying setting information for setting various operation modes of the audio device.

FIG. 2 is a flowchart when the review key is pressed to turn on the review. In FIG. 2, when the number of types to be referred to in the review mode is "n", "n" is set to 1 at first (step S101), and the review "n = 1" is displayed (step S102). The display example of each review in which “n” is 1 to 5 in the tuner setting state is as follows.

1. “REVIEW” 2. 2. “MANUAL” or “SEEK” 3. “DX MODE” or “LOCAL” 4. “DIV ON” or “DIV OFF” "MUTE OFF" or "MUTE ON" Here, "MANUAL" and "SEEK" indicate whether the setting of the reception mode is a manual adjustment or a seek state for automatically searching for a radio wave. "DIVON",
“DIV OFF” indicates whether the antenna is in the diversity mode.

This display is made for a certain period of time (in this case, 5 seconds), and it is determined whether or not 5 seconds have elapsed (step S103). When the time has elapsed, or when the review key is pressed before 5 seconds have elapsed. Is (step S104),
“N” is incremented by 1 (step S10)
5). Then, it is determined whether or not "n" is final (step S106).
02, the next review is displayed. If “n” is final, this flow ends.

As described above, even when there is only a display portion having a limited number of characters, a review key is provided as setting information reference means for automatically and continuously displaying each setting information in a predetermined order for a predetermined time. Thus, all setting states can be confirmed.

[0021]

According to the present invention, as is apparent from the above embodiment, each setting information for setting each operation state of the receiving means, the playing means and the sound correcting means is displayed on the display means for a certain period of time.
With the provision of the setting information reference means for displaying in a predetermined order, a large amount of setting information, and even those not related to the current operation mode, can be displayed on the display means with a limited number of display characters. .
