Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio device, and more specifically, to audio suitable for use in an audio system that reproduces a music source recorded on a recording medium such as a compact disk or a cassette tape. Regarding the device.

Conventional technology Many recording media, such as compact discs (so-called CDs) and cassette tapes that contain music programs, or digital audio tapes (so-called DAT), record multiple songs in the so-called omnibus format. In addition to the normal continuous playback function, the system of the audio device that plays back the audio is an automatic cue (so-called APS) function that can selectively play back the recorded content of each recording medium, and a scan function for searching the recorded content. It is equipped with a function so that the user can select the operation mode according to his or her needs. Here, the scan function is a function for continuously performing so-called intro reproduction, in which only the head portion of each program recorded in the omnibus format is sequentially reproduced for, for example, about 10 seconds.

Problems to be Solved by the Invention However, in the programs recorded in the omnibus format as described above, the recording level and the sound quality may be different for each song, and in particular, they are recorded personally on a cassette tape as a recording medium. The tendency is remarkable for the programs that were conducted. Therefore, when playing such a recording medium in continuous playback mode, the volume level and sound quality are different for each song, but in most cases, the volume and sound quality set at the beginning are played continuously. It is often played back as an imperfect sound.

Therefore, in order to listen to such programs in the optimal state, it is necessary to adjust the sound quality adjustment means such as the volume adjuster and the graphic equalizer each time the song changes, and often adjust the volume and sound quality while listening. I had to readjust the vessel.

An object of the present invention is to solve the above problems and to provide an audio device capable of obtaining a reproduction sound required by a user even during continuous reproduction.

Means for Solving the Problems The present invention provides an audio device for performing a search of recorded content while sequentially reproducing recorded content that is divided and recorded on a recording medium for each predetermined interval for a predetermined time. Sound quality adjusting means for adjusting the sound quality of the sound; and storage means for storing the operation state of the sound quality adjusting means set within the predetermined reproduction time for each of the divided recorded contents. It is an audio device.

Action The audio device according to the present invention sequentially reproduces the recorded contents recorded by being divided into the recording medium for each of the divisions for a predetermined time, while operating the sound quality and volume of the reproduced sound by the sound quality adjusting means, Adjust and set for each recorded content.

The operation state of the sound quality adjusting means set for each divided recording content is stored by the storage means, and at the time of reproduction, the recording content is reproduced based on the stored content.

Embodiment FIG. 1 is a block diagram showing the electrical configuration of an audio device according to an embodiment of the present invention. The audio device 1 has input terminals A, B,
Via C to lines 1, l2, l3, compact disk (C
D), digital audio tape (DAT), cassette tape (TP), and other reproduction signals from recording media are input.

When the user operates an input selection key (not shown) provided on the operation unit 2 to select a desired input, the selection result is a central processing unit (hereinafter referred to as CPU) 3 via a line l4.
CPU3, input switching signal S1 based on the above selection.
To the input switching circuit 4 via the line 15 to select the reproduction signal input. The selected input signal enters an electronic graph equalizer (hereinafter abbreviated as equalizer) 5 which is a sound quality adjusting means for adjusting the sound quality of the reproduced sound, is set to a desired frequency characteristic, and further, a volume / sound quality adjusting circuit 6 is provided.
After the volume level, low frequency range and wide range characteristic are set through the above, the signal is amplified by the amplifier circuit 7 and drives the speaker 8 to be sonicated.

The operation unit 2 is provided with an operation mode selection key, a memory key, etc., which are not shown, in addition to the input selection keys described above, and the operation mode selection keys include a scan mode, an automatic head mode in addition to the normal continuous playback mode. Includes operation specification keys for start (so-called APS) mode, fast forward, rewind, stop, etc. Further, as will be described later, the memory key is operated at the time of scanning reproduction after the scanning mode is selected. , l9
It is input to the CPU 3 via the and is stored in the data area of the first memory 10a which is a storage means provided in the CPU 3.
The above stored data is read during continuous playback,
The reproduction operation based on the set data is executed.

In addition to the data area, the first memory 10a has an operation mode area for storing operation modes, a song number area selected for the APS mode and a song number area for storing song numbers corresponding to the skimming mode, and a timer setting time not shown. A random access memory (so-called RAM) that is freely writable and readable is provided with a timer area for storing. Further, the second memory 10b stores adjustment data of the equalizer 5 corresponding to music types to be reproduced, for example, rock, pops, vocals, etc., and a music type selection key in the operation unit 2 during reproduction or recording. By operating (not shown), data corresponding to the selected music quality is automatically given to the equalizer 5 and set to the characteristic corresponding to the music.

Via lines 1a and l2a branched from the lines 1 and l2,
Compact disk CD and digital audio tape DAT
The initial data for each song recorded in and the signal indicating the interval between songs are input to the CPU3. Also, when the reproduction signal from the cassette tape TP is input to the CPU3 via the line l3b branched from the line l3a, and a silent portion between songs is detected,
By comparing with a predetermined time, the CPU 3 judges whether it is in the middle of a song or between songs, and when it judges that it is between songs, a song number is added and the first memory 10
Stored in the song number area of a. In this way, the programs from the cassette tape are also sequentially stored with music numbers.

A display signal is given from the CPU 3 to the display unit 12 via the line 10. The display unit 12 is realized by a light emitting diode, a liquid crystal element, or the like, and displays a tape counter, the number of the currently reproduced song, the selected song number, or the operation mode.

In the present invention, the skip mode is selected, and a so-called omnibus-type music program that is recorded separately on the recording medium is played back for a fixed time (for example, 10 seconds in this embodiment) at the beginning of each song, During this playback time, the user listens to the content of each song, adjusts the sound quality adjusting means so that the volume and sound quality are adapted to the song, stores the adjusted content in the storage means, and continuously reproduces the mode. At times, reproduction is performed based on the stored data. As a result, it is possible to continuously reproduce the omnibus-type music programs recorded in different states without having to make adjustments during the continuous reproduction, and at the same volume and sound quality desired by the user. The operation will be described below.

FIG. 2 is a flow chart for explaining the operation in the scan mode of this embodiment. Before starting the operation, it is assumed that a recording medium such as a compact disc, a digital audio tape or a cassette tape is already mounted.

Referring also to FIG. 1, in step a1, the operation unit 2
When the scan mode key is turned on and the scan mode is selected, the CPU 3 reads it and sets the scan flag of the operation mode area of the first memory 10a to 1 at step a2. When the input is selected and the place switch is turned on in step a3, the music number = 0 is stored in the music number area of the first memory 10a in step a4, and the reproduction is started in step a5.

At step a6, it is determined whether the skimming mode is released. This is determined to be released when the skian mode key is turned on again when the skian flag is set to 1, and in the case of the skian mode release, the operation goes to step a23 to set the skian flag to 0, and the skian mode is made at step a24. Is released. If it is not canceled, the process proceeds to step a7, and one song is played.

When the playback signal is also input to the CPU 3 as described above and the beginning of the song is detected, the CPU 3 sets 1 in the song determination flag in the song number area of the first memory 10a, and in step a9, the song number = 1 The counter 11 is activated at step a10, the time T from the beginning of the music is counted, and compared with a predetermined time Ta. In the present embodiment, the set time Ta is, for example, 10 seconds, during which the beginning portion of the song is so-called intro-played.

In step a11, the user confirms whether or not the reproduced sound quality is desired during the intro reproduction, and the operation unit 2
Operate the music quality selection key of. Either automatic or manual is selected for the music quality setting key, and in the case of automatic, multiple music quality setting keys corresponding to music programs such as jazz, pops, vocals and musical instruments can be selected depending on the music quality It is located in. At step a12, it is determined whether the music quality setting is automatic or manual. If automatic, step
At a13, the data corresponding to the music quality set at the same time is read from the second memory 10b. If it is manual, the process proceeds to step a14, and the user operates the equalizer 5 via the operation unit 2 so that desired acoustic characteristics can be obtained. As a result, the characteristic of the equalizer 5 is set at step a15.

In the following step a16, the user selects the sound / sound quality adjustment circuit 6
Is operated to set a desired volume level and low-range / high-range characteristics, so-called loudness characteristics. The data set in this way is input to the CPU3 via lines l8 and l9,
It is stored in the data area of the memory 10a.

At step a19, it is judged whether or not the intro reproduction time T counted by the counter 11 has reached a predetermined time Ta (for example, 10 seconds in this embodiment). When it reaches, step a20 is proceeded to, and the CPU 3 resets the in-music confirmation flag to 0, and the counter 11 is reset at step a21. This completes the intro reproduction of one song, data setting during that time, and storage in the first memory 10a, and the beginning of the next song is detected in step a22.

This is done by detecting the song number signal for a song number that has been recorded in advance, such as a compact disc or a digital audio tape, and for those that do not have the song number recorded, such as a cassette tape. This is performed by detecting a non-recorded portion, that is, a silent portion, which is interposed between songs. When the beginning of the next song is detected, the process returns to step a6, and the same operation as above is continued until the end song or until the scan mode is released, and the volume and sound quality of each song are set at the level desired by the user. Will be stored.

FIG. 3 is a flow chart for explaining the operation in the continuous reproduction mode of this embodiment. Here, the continuous playback mode refers to the case where the program in which the data for each song is stored in the first memory 10a is played back in the above-described scan mode, and is already a recording medium such as a compact disc, a digital audio tape, or a cassette tape (general term: When it is done, it is assumed that the program is installed).

When the continuous reproduction mode is selected by the operation unit 2 in step b1, the CPU 3 sets the reproduction flag in the operation mode area in the first memory 10a to 1 in step b2. When the reproduction key is turned on at step b3, the reproduction of the program is started at step b4 and the reproduction signal is also input to the CPU3. At step b5, the data of the music number previously recorded in the program is read. The read data is stored in the first memory at step b6.
It is collated with the music number stored in 10a and the corresponding data is read from the first memory 10a. The read data is given to the equalizer 5 and the volume / sound adjusting circuit 6 via the lines l8 and l9, and the equalizer characteristic and the loudness characteristic based on the data are set respectively, and at step b9, one program of the program is set as described above. Playback is performed based on the specified characteristics.

At step b10, it is judged whether or not the reproduction of the song is finished. In a program such as a compact disc or a digital audio tape in which the inter-track signal is recorded in advance, when the inter-track signal is detected, it is judged that one song has ended, and the inter-track signal is recorded like in the cassette tape. In a non-program, a non-recorded portion, that is, a silent portion, which is interposed between songs is detected, and it is exceeded by comparing with the counter 11 whether the silent portion has continued for a predetermined time (for example, 2 seconds). In this case, it is determined that one song has ended.

At step b11, it is judged whether or not the reproduction is canceled. When the reproduction key is turned on while the reproduction flag 1 is set, it is determined that the reproduction is to be released, the process proceeds to step b12 to set the reproduction flag to 0, and the reproduction mode is released at step b13. If reproduction is continued, the process returns to step b5, and the same operation as described above is executed until the end or the reproduction is canceled.

EFFECTS OF THE INVENTION As described above, the audio device according to the present invention sequentially reproduces the recorded content of the music program recorded in the recording medium in the skip mode for a certain period of time, and the user reproduces the above. While monitoring each song at time, operate the sound quality adjustment means to individually adjust to the sound quality and volume suitable for each content, and the adjusted operation state of the sound quality adjustment means as data for each song It is stored in the storage means. When playing back in the continuous playback mode, by sequentially playing back based on the above-mentioned stored data, even if it is a so-called omnibus format music program that is recorded separately in different states, it is still in the middle of playback. There is no need to make adjustments, and usability is dramatically improved.
