Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a display system of mobile audio devices which enables comparative displays between a frequency range of audio sources read from outside and memorized in the main body of mobile audio devices and a frequency range replayed at the main body of the mobile audio device.

2. Description of Related Art

In accordance with improvement of functions in mobile audio replay devices, replay devices with higher sound quality have been requested increasingly. As results, as for audio sources of music, devices which memorize higher sampling frequencies than CD (sampling frequency 44.1 kHz) such as 96 kHz or 192 kHz with high sound quality begin to be sold.

However, although an audio source is with a high sound quality, it is unknown if an audio replay device can be replayed with such sound quality as making the best use of the sound source.

Conventionally, although an earphone is connected to a mobile audio replay device by cord, devices have been known that multiple LEDs are equipped on the way of the cord and these LEDs turn on by light emitting brightness, plain color, color, fixation, blinking, revolving lantern, water-flow simulation dynamic state etc. (for example, patent reference 1).

Embodiment 1

Embodiment 1 of the display system of mobile audio devices in the present invention is explained, based on FIGS. 1 and 2.

In FIG. 1, 10 is a main body of a mobile audio device and in the main body of the mobile audio device 10, a display part 11 is equipped and the replay unit 14 such as earphone is connected. In said display part 11, the audio source output display part 12 and the replay output display part 13 which are specific for the present invention are equipped.

The controller 15 is mounted inside said main body of the mobile audio device 10 and the controller 15 is connected to the replay unit 14 comprising an earphone, the audio-source file 18 memorizing audio sources read from an outer audio-source data 19 and compressed, the device data memory 16 memorizing device data of the main body of the mobile audio device 10, and an input system 17 such as touch panel.

The output side of the replay unit of said controller 15 is connected to the file format output 20 outputting names of file formats memorized in the audio-source file 18 and the sampling rate output 21 analyzing sampling rates of compressed files memorized in the audio-source file 18 and outputting them. Those of 20 and 21 are then connected to said audio-source output display part 12.

At the output side of the replay 14 of said controller 15, the device data output 22 outputting device data from device data input from the device data memory 16 and replay sampling rate output 23 analyzing replay sampling of the main of the mobile audio device 10 used currently and outputting it are connected and then connected to the replay output display part 13.

Actions of such configuration are explained.

Outer audio-source data from the outer audio source data 19 such as internet, personal computer, and CD etc. are memorized at the audio source file 18 through the controller 15 by operating the input system 17 of the main body of the mobile audio device 10. The audio source file 18 memorizes outer audio source data in compressed conditions with high sound quality at sampling rates of high frequencies such as 192 kHz and 96 kHz or in non-compressed conditions or at other sampling rates of lower frequencies. Those are mixed in the memory.

When audio sources memorized at the audio source file 18 are taken in the file format output 20 and the sampling rate output 21 by operating the input system through the controller 15, in the file format output 20, [compressed file names] are output and displayed at the file name display part 24 of the audio source output display part 12. In the sampling rate output 21, frequencies of audio sources from the audio source file 18 are analyzed, converted to sampling rates and “96 kHz” is digital-displayed as a numerical data and bar graphs with fine intervals of 0-96 kHz are analogue-displayed to be recognizable at first glance.

As for replay data output at the replay unit 14 from the controller 15, names of devices of the main body of mobile audio device 10 are output and displayed at the replay device name display part 27 of the replay output display part 13. At the same time, sampling rates at the replay are output, based on frequency data in the main body of mobile audio device 10 and “48 kHz” as a numerical data is digital-displayed and bar graphs with fine intervals of 0-48 kHz are analogue-displayed to be recognizable at first glance.

Despite 96 kHz for audio-source data memorized at the audio source file 18, such displays enable to become recognizable at first glance that the replay is made with 48 kHz. In addition, when the displays of the audio-source output display part 12 and the replay output display part 13 are identical, it is understandable that the main body 10 of the mobile audio device replays as making sufficient use of the audio source.

In said embodiment, names of replay devices are displayed at the replay device name display part 27 of the replay output display part 13 by output from the device data output 22. However, when data of replay device names are absent or aren't discriminant, “OTHERS” is displayed, this including replay device names.

In said embodiment, as shown in FIG. 1, the replay unit 14 is connected externally to the main body of the mobile audio device 10 by lead wires. The replay unit 14 includes items set inside the main body of the mobile audio device 10.

In said embodiment, the audio-source output display part 12 and the replay output display part 13 are arranged with one each. For instance, in case that LR signal is present, the audio-source output display part 12 and the replay output display part 13 are arranged with two or more each.
