[Problems to be Solved by Prior Art and Invention]

 In an audio device such as a radio-cassette equipped with a CD (compact disc) player, that is, a CD radio-cassette, a user can arbitrarily reproduce a desired song from one CD containing a plurality of songs, that is, a song number. It can be specified (perform a search operation), but if the sound pressure level at the beginning of the specified song is low, the user (audience) may not be able to hear it.

A general CD player including a CD radio-cassette is equipped with a display unit for displaying a so-called P-TIME display, which shows the elapsed time of a performance song by a number. However, in the case of a so-called CD karaoke device in which a CD player is applied to a karaoke device, for example, the user is often away from the device, in which case the P-TIME display is difficult to see. Therefore, if the opening sound of the song is small and the volume of the device is narrowed down to a certain extent or more, the beginning of the song (accompaniment music) may be difficult to understand and the beginning of the song may fail, especially in karaoke snacks where the surroundings are noisy. There was a shortcoming.

[Means for Solving the Problems]

 The present invention relates to an audio device having a CD player (section), a tape recorder (section), and a tuner (section), and a display section capable of changing display colors and the like, and detecting the operation state of the apparatus to change the state. The above problem was solved by further comprising a system controller that changes the color of the display unit according to the above.

[0005]

[Embodiment] An embodiment of an audio device of the present invention will be described with reference to the block diagram of FIG. In this figure, 2 is a microcomputer (system controller), 3 is a display section, 5 is a tape recorder (section), 6 is a tuner (section), 7 is a CD player (section), and Sw is a changeover switch. That is, FIG. 1 is an example in which the audio device 1 of the present invention (hereinafter also simply referred to as the “device of the present invention”) 1 is applied to a CD radio cassette player, and when each part is integrally configured, 5, 6, 7 Are tape recorders, tuners, and CD players, respectively. When they are formed separately (or separably), 5, 6, and 7 are tape recorders, tuners, and CD players, respectively.

The display section 3 is not a display section for the P-TIME display, but has a function such that the operating state of the device 1 of the present invention can be clearly understood even from a relatively distant place. Has become the greatest feature of. More specifically, for example, the color is changed in accordance with the operating state of the device 1, and the device 1 is arranged at a location easily visible such as a panel on the front surface of the device (not shown). The example of FIG. 1 shows a configuration example in which the color changes to two colors. 4a is, for example, a green light emitter (lamp such as an LED), and 4b is, for example, a yellow (amber) light emitter. The shape of the display unit 3 is not limited to that shown in FIGS.

Next, specific functions and operations of the device 1 of the present invention will be described with reference to the flowchart of FIG. First, when the power of the apparatus main body is turned on (closed), the microcomputer 2 connects the changeover switch Sw to, for example, the terminal a side in the initial state, and causes the display unit 3 to emit green light. At this time, if the device 1 has a mode display device, the mode display is "CD" or "tape". Next, when the user operates a tuning (tuning) knob (not shown) provided on the tuner section 6 (steps to), it is green (step) during detuning and tunes to any broadcasting station. When it is detected (that is detected), the switch Sw is switched to the terminal b side to emit yellow light (step).

On the other hand, even when the reproduction button (not shown) of the tape recorder unit 5 or the CD player unit 7 is pressed (step,) instead of operating the tuning knob, the switch Sw is switched to the terminal b side. It emits yellow light (step), and in other modes (fast forward, rewind, search, etc.), it emits green light (step). Each of the above operations can be performed by a predetermined remote controller. In addition, it is more convenient if the color is configured to change when the song selection search ends and the song starts playing (when the P-TIME display reaches 00:00). Not only the colors but also the number of colors of the light-emitting body 4 is increased and it is more convenient to use three or more colors, and the effect of rendering (color rendering) can be produced.

Next, a specific configuration example of the display unit 3 will be described with reference to the sectional view of FIG. 2 and the front view of FIG. The display unit 3 uses a horizontally long reflector 13 as shown in FIG. 3 also as a case, and covers the front edge thereof with a semi-transmissive reflector 11 as shown in FIG. 2 and further LCD (Liquid Crystal) on the surface thereof. Display) 12 is provided by sticking or the like. The semi-transmissive reflection plate 11 is formed by laminating, for example, a green laminate 14, a transparent ENVI (vinyl chloride resin) 16, and an irregular reflection uneven material 17, and when the light-emitting body 4a or 4b is turned on, the LCD 12 is substantially in a uniform state. Function to emit light. That is, the semi-transparent reflection plate 11 reflects a part (a predetermined amount) of the direct light from the light-emitting body 4a or 4b and the reflected light from the reflection plate 13 and transmits the rest.

It should be noted that the laminate 14 may be omitted, but by using a laminate having a color close to the color of the light-emitting body, it is possible to reduce color turbidity and to finally obtain two types of desired colors. By making the color of the light-emitting body 4a or 4b as close as possible to the color, it is possible to reduce the color variation. A half mirror may be used instead of the semi-transmissive reflector 11.

On the other hand, as shown in FIG. 3, a plurality of holes 8a and 8b are provided at a plurality of positions (substantially evenly spaced) on the substantially center line of the reflection plate 13. At a position corresponding to the plurality of holes 8a and 8b, for example, green and yellow light-emitting bodies 4a and 4b of different colors are arranged on the substrate 15 in pairs, for example, and the holes 8a and 8b are penetrated respectively. Projecting forward. Therefore, the light emitters 4a and 4b function as a backlight of the LCD 12, and the entire LCD 12 emits a bright light. Therefore, when the switching switch Sw is connected to the terminal a side to turn on the light emitter 4a, the LCD 12 (that is, the display unit 3) glows green, and the switch Sw is connected to the terminal b side to turn the light emitter 4b on. When turned on, the LCD 12 emits yellow light.

The number of types of light emitters is not limited to two and may be three or more. However, if the switch Sw can be connected to both terminals a and b at the same time, the light emitters 4a and 4b can be connected. It is also possible to display an intermediate color (yellow-green in this embodiment) of, which allows the operation state (type) to be displayed in three different ways with the two types of light emitters.

Further, as shown in FIG. 5, there is only one kind of light emitter (white, for example), and the light emitter 4 is configured to blink by turning the switch Sw ON and OFF. It is also possible to display the operation (change) of the device 1 by changing it in 2. In any of these embodiments, the operation (change) of the device 1 can be judged from a relatively distant place, and especially when applied to a karaoke device, the start of a song can be surely judged, so that there is a practical feature that it is possible to sing with confidence. is there.

In the above description, the audio device of the present invention is applied to a CD radio-cassette player or a CD karaoke device, but the present invention is not limited to this, and may be applied to an LD karaoke device or a general stereo device. Of course.
