Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a commercial playback device, and in particular is configured to normally broadcast music and to suppress this music signal when broadcasting a commercial.

Conventionally, even if only the advertising text was continuously announced during advertising broadcasts, there would be little interest among the customers who listen to it, so music is usually broadcast and advertising advertising texts called commercials are usually announced in the middle of the broadcast. things are being done. For this purpose, music was usually played continuously on a tape, and when an advertisement was to be inserted, a person would interrupt the music signal and play an advertisement instead. Therefore, human intervention was required to interrupt this music signal. Therefore, in order to make this manual labor unnecessary, it was necessary to pre-record music and advertisements on magnetic tape and then play them back. Therefore, it is necessary to prepare magnetic tapes on which such special contents are recorded, and it is impossible to change the music inserted between the advertising texts. Therefore, if the music was to be changed, it was necessary to re-record the magnetic tape.

Therefore, in the present invention, the music to be inserted between the advertisements can be inserted at appropriately selected intervals without fixing the music, and the advertisements can be inserted at appropriately selected intervals. A commercial playback device equipped with a fade-in/fade-out method in which the volume of the music that has been broadcast until then is not abruptly interrupted when the music is inserted, but the volume of the music is gradually lowered, and the volume of the advertising text is gradually increased. The purpose is to provide For this purpose, the commercial playback device of the present invention alternately broadcasts music and advertising text, and includes a music signal generating means for generating a music signal, and an advertising recording means on which the advertising text is recorded. , a recording/reproducing means for reproducing the advertising recording means, a switching means with fade-in/fade-out, and a timer, and the output of the timer controls the switching means with fade-in/fade-out so that the music signal is always controlled. The present invention is characterized in that the music obtained from the generating means is broadcast and the advertisement text is automatically broadcast instead of the music at the time selected by the timer.

An embodiment of the present invention will be described below based on FIGS. 1 and 2.

FIG. 1 is a circuit configuration diagram of an embodiment of the present invention,
FIG. 2 is an explanatory diagram of the operation.

In the figure, 1 is a music signal generating section, 2 is a tape reproducing section, 3 is a timer, 4 is a fade-in/fade-out switching section, 5 is an amplifier, and 6 is a speaker.

The music signal generating section 1 generates a so-called music signal, and is composed of an LP record playback section, a magnetic tape playback section, and the like.

The tape reproducing section 2 is for reproducing a magnetic tape on which advertising text is recorded. In this case, it is desirable that the magnetic tape used in the tape reproducing section 2 be endless. A specific frequency can be recorded on the magnetic tape as a stop signal generating means, or metal paper can be pasted on the magnetic tape.

The timer 3 generates a control signal for the tape reproducing section 2 and the fade-in/fade-out switching section 4 after the set time has elapsed.

The switching section 4 with fade-in/fade-out is
A music signal transmitted from a normal music signal generating section 1 is transmitted to an amplifier 5, thereby broadcasting music from a speaker 6. However, when a control signal is applied from the timer 3, the signal transmitted from the music signal generator 1 is gradually suppressed to a smaller value, and instead, the signal transmitted from the tape reproducing section 2 is controlled to be gradually larger. The sum of both signals is transmitted to amplifier 5. Therefore, when the control signal from the timer 3 is transmitted to the fade-in/fade-out switching section 4, the music being broadcast from the speaker 6 gradually becomes quieter, and the advertising message transmitted from the tape playback section 2 becomes louder. It will be gradually broadcast on a larger scale.

In FIG. 1, a tape playback unit 2, a timer 3,
It is desirable that the fade-in/fade-out switching unit 4, amplifier 5, and speaker 6 be configured as one set A. However, music signal generator 1
can be incorporated into set A, but it is preferable to use an external music signal generating device such as a cable broadcasting device.

Now, during period #i-1 in FIG. 2, a music signal transmitted from the music signal generator 1 in cable broadcasting is transmitted from the fade-in/fade-out switch 4 to the amplifier 5, and music is played from the speaker 6. ing. Therefore, if this set A is installed in beauty salons, coffee shops, etc., customers of these shops listen to music broadcast by cable. Then, at time T _i in FIG. 2, the timer 3 operates to start the tape playback section 2 and play back the endless tape on which a commercial has been recorded, for example, and the fade-in/fade-out switching section 4 switches the tape playback section 2 to start the tape playback section 2. The switching operation is performed so that the signal transmitted from the amplifier 2 is applied to the amplifier 5. Moreover, in this case, as shown in period _L1 in FIG. 2, the fade-in is performed so that the signal transmitted from the music signal generating section 1 is gradually attenuated and the signal transmitted from the tape reproducing section 2 is gradually increased. The switching section 4 with fade-out functions. As a result, the speaker 6 gradually lowers the volume of the music, and instead broadcasts the commercial transmitted from the tape playback section 2 gradually louder. In this way, the advertising text can be broadcast during period #i over background music at a low volume. In this way, customers are comfortable listening to commercials.

Then, at time T _i+1, when the endless tape in the tape reproducing section 2 has made one revolution and approaches the end, the tape reproducing section 2 detects this one revolution using a well-known means such as a sensor, and performs a fade-in. - Sends a control signal to the switching section 4 with fade-out, and acts to transmit the music signal transmitted from the music signal generation section 1 to the amplifier 5 again. In this case, the time
In contrast to T _i , it acts to gradually increase the signal transmitted from the music signal generator 1 and gradually decrease the signal transmitted from the tape playback section 2,
These signals are smoothly switched during period _L2 in FIG. As a result, in period #i+1, cable broadcast music is played again from the speaker 6. By repeating this process, music and advertising text can be broadcast alternately.

In this way, according to the present invention, the music signal generation section and the commercial signal generation section can be made separate, and the advertising text can be broadcast at a predetermined time set by a timer. becomes possible.

Therefore, according to conventional means, if you want to broadcast 50 minutes of music and 10 minutes of advertising text, you must create a 60-minute tape that records the music and advertising text together. Even when copying this to another tape using the double-speed recording method, it still took 30 minutes to create this 60-minute tape. And when the advertising text changes from store to store, it takes at least 60 minutes to create a 60-minute tape. Furthermore, when such tapes are used, the content to be broadcast is fixed by the tape, and it is not possible to broadcast advertisements at arbitrary times.

However, as described above, according to the present invention, a tape is used to record only the advertising text, and other playback parts are used for the music, so the tape creation time only needs to be the recording time for the advertising text. It only takes a very short time. Moreover, by simply changing the timer setting, it is possible to broadcast advertisements every 60 minutes or every 120 minutes at any time. Furthermore, the fade-in/fade-out switching section gradually lowers the volume of the music and broadcasts the commercial gradually louder, so the customer can listen to the commercial without any resistance.

In the above description, an example has been described in which the amplifiers and speakers in set A are used, but of course other amplifiers and speakers may be used.
