Abstract

(57) [Summary] [Purpose] Make it easier to identify each song by skip playback. [Structure] When S1 is first executed, the first music piece is searched and the reproduction is started from that position. In addition, next,
When step S1 is executed, the next track searched last time is searched. Next, in S2, it is determined whether or not the reproduction of the vocal portion has started. If it has started, the process proceeds to S4, and if not, the process proceeds to S3. In S3, it is determined whether or not the skip reproduction operation is stopped. If it is stopped, the skip reproduction operation is ended, and if not stopped, S2 is repeated. In S4, it is determined whether or not the vocal part has ended, and if it has ended, the process proceeds to S1, and if not, the process proceeds to S5. S
At 5, it is determined whether or not the skip reproduction operation is stopped. If it is stopped, the skip reproduction operation is ended, and if not stopped, S4 is repeated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an audio device for reproducing a recording medium such as an audio cassette tape, a compact disc, and a DAT in which a plurality of songs are recorded, and more particularly to a skip reproducing function thereof.

[0002]

[Prior art]

 Conventionally, in an audio device that plays back a recording medium on which a plurality of songs are recorded, such as a CD player or DAT, as an introduction scan play, the song is played for a unit time from the beginning of the song and forward skipped to the next song to start the song. There was a function to repeat playback for a unit time.

[0003]

[Problems to be solved by the device]

 In the above-mentioned introduction scan play of the conventional audio equipment, since every song is uniformly played for a unit time and skipped to the next song, it is not possible to distinguish which song depending on the song and the function desired by the user is not provided. There was a problem that it could not be provided.

The present invention has been made in view of the above points, and an object thereof is to reproduce from the beginning of a song to the break of the audio signal part, a so-called vocal part, when the beginning part of the song is skipped and reproduced. It is to provide an audio device that does.

[0005]

[Means for Solving the Problems]

 The audio equipment of the present invention is a sound equipment capable of reproducing a recording medium on which a plurality of songs are recorded and searching the beginning of the music, and is provided with a circuit for detecting the presence or absence of an audio signal from a reproduction signal. A structure configured to repeat the process of searching the beginning of the next song, searching for the beginning of the next song, and playing until the end of the audio signal, when skipping the beginning of the song Is.

[0006]

[Action]

 According to the audio device of the present invention, since from the beginning of the song to the break of the audio signal during skip playback, it is possible to reliably determine what the song is for all songs.

[0007]

【Example】

 An audio device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a CD player which is an embodiment of the present invention.

In the figure, reference numeral 2 denotes a CD reproducing device for reproducing recorded data of a CD and a subcode signal, which is instructed by the control microcomputer 1 to search and reproduce an arbitrary track. The audio signal and the subcode signal are demodulated from the recorded data reproduced by the CD reproducing device, the audio signal is output to the audio signal detection circuit 3, and the subcode signal is output to the control microcomputer 1.

The audio signal detection circuit 3 is composed of a bandpass filter or a DSP, outputs the input audio signal to the mute circuit 4, detects the presence or absence of the audio signal, and outputs a signal indicating the presence or absence of the audio signal. Output to control microcomputer 1.

The mute circuit 4 outputs the voice signal input based on the command from the control microcomputer 1 to the amplifier 5 as it is or mutes the voice signal. The amplifier 5 amplifies the input audio signal and drives the speaker 6.

The control microcomputer 1 is a microcomputer having a built-in RAM and ROM, operates according to a program written in the ROM and a signal input from the operation keys 8, operates the CD reproducing device, and operates the CD. The recording information of TOC (table of contents) reproduced by the reproducing device is stored in the RAM, the mute command is output to the mute circuit 4, and the reproduced music number and the like are displayed on the display device 7.

Next, the skip reproduction operation (phrase scan operation) of the CD player will be described with reference to FIG.

When the skip reproduction operation is instructed by the operation keys 8, first, step S1 is executed. When step S1 is first executed, the first tune (track number 1) is searched and the reproduction is started from that position. When step S1 is executed next time, the next track searched previously is searched.

Next, in step S2, it is determined whether or not the reproduction of the vocal portion is started. If it is started, the process proceeds to step S4, and if not, the process proceeds to step S3.

In step S3, it is determined whether or not the skip reproduction operation is stopped by the operation key 8. If it is stopped, the skip reproduction operation is ended, and if not stopped, step S2 is repeated.

In step S4, it is determined by the signal from the audio signal detection circuit 3 whether or not the vocal part has ended, and if it has ended, the process proceeds to step S1, and if it has not ended, the process proceeds to step S5.

In step S5, it is determined whether or not the skip reproduction operation is stopped by the operation key 8. If it is stopped, the skip reproduction operation is ended, and if it is not stopped, step S4 is repeated.

In this way, the reproduction from the beginning of each music piece to the break of the voice signal is repeated until the operation key 8 is pressed. Although the embodiment has been described with respect to the example of the CD player, the invention is not limited to this, and the invention can be applied to the reproduction of an ordinary cassette tape or DAT, for example.

[0019]

[Effect of the device]

 According to the audio device of the present invention, in skip reproduction, it is possible to determine the content of a piece of music even if the introduction part has a long prelude.

Further, in skip reproduction, the beginning portion of each music is not reproduced for a unit time as in a conventional audio device, and skipping is performed after waiting for a break between music, so that a feeling of strangeness is eliminated.
