Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an audio information automatic performance device used for guidance and campaigns of various products, events, exhibitions, etc., as well as unmanned information boards and security systems. In particular, the present invention relates to an audio information automatic performance device that automatically plays audio information when the start time approaches while BGM is being played.

(Prior Art) Conventionally, when conveying audio information to unspecified people gathered at or passing through a predetermined location, an announcer stands by or records the information on a tape recorder and then broadcasts the information for an appropriate period of time. It was played either by broadcast or by hand at intervals or when someone was present.

There is also a system that uses a voice synthesizer/player with built-in SRAM instead of a tape recorder to automatically play voice information at appropriate time intervals.

(Problem to be solved by the invention) However, in many cases, it is practically impossible to have an announcer on standby due to cost considerations. on the other hand,
When using a tape recorder, manual operation is required in order to provide audio information at the appropriate time, which is still problematic in terms of cost, and if a short recorded portion is played back many times, the tape will be damaged and the sound quality will deteriorate. There is also the problem that the sound quality decreases, making it difficult to hear.

Furthermore, if you want to play BGM while playing audio information in the middle of the continuous performance of a tape recorder using an endless tape, the BGM
There is a problem in that it is necessary to record the audio information together with the audio information, which requires a great deal of effort to edit the tape. However, there is a problem in that the audio information may not be provided accurately due to the flow of the audio information. Furthermore, if the content of the audio information changes, it is necessary to edit it again from scratch.

Furthermore, when a voice synthesis/playback device is used, only short-term voice information is played at time intervals, and there is a problem in that the voice information cannot be conveyed comfortably and effectively to the listener. In addition, if you want to use it together with the always-playing BGM, you can play the BGM on a separate performance device.
Since the music is played, the BGM and audio information mix, making it difficult to hear, and resolving this problem requires human intervention.

In view of the above conventional problems, the present invention aims to provide an audio information automatic performance device that can automatically play audio information when a person approaches while BGM is being played.

(Means for solving the problem) In order to achieve the above-mentioned purpose, the present invention provides an IC cassette with a built-in EPROM for recording audio information, and an IC cassette containing an EPROM for recording audio information.
an audio synthesis section into which an IC cassette is attached and which synthesizes an audio signal from the audio information; a BGM input section which inputs a BGM signal; a mixer section which mixes the signals from the audio synthesis section and the BGM input section; A flat speaker that is activated by the output, a sensor that detects the proximity of a person, and a detection signal from this sensor that activates the audio synthesis section and controls the mixer section so as to reduce the volume level of BGM during the operation. The present invention is characterized by comprising a control section that performs.

(Function) Since the present invention has the above-mentioned configuration, when a person approaches while BGM is being played, the sensor detects it, the voice synthesis section is activated, and the sound is recorded from the flat speaker to the IC cassette via the amplifier section. The recorded audio information will be played automatically. At this time, the volume level of the BGM is lowered, so you can hear the audio information clearly. Moreover, the BGM is played at a low volume without cutting out, so the noise peculiar to synthesized voices is not noticeable, and the sound is clear. can convey information. Furthermore, since an EPROM is used for the IC cassette, it can be rewritten, and there is no need for backup as is the case when SRAM is used. Furthermore, since we use flat speakers, you can paste posters or write pictures or letters on the surface of the speakers.
It can be combined with visual information to further enhance the information transmission effect.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 denotes a performance device body to which an IC cassette 2 is attached and plays audio information.
The IC cassette 2 has a built-in EPROM, that is, a programmable ROM that can be erased and rewritten, and records audio information read out by a specialized announcer. Furthermore, when the information to be transmitted changes, this IC cassette 2 can be used repeatedly by erasing the previous information and rerecording the new information.

The performance device main body 1 is equipped with a voice synthesis section 3 that reads voice information from an attached IC cassette 2 and synthesizes a voice signal, and is also provided with a control section 4 that controls the operation of this voice synthesis section 3. There is.

An output signal from a sensor 5 that detects the approach of a person is input to the control unit 4 via a sensor amplifier 6, and is configured to activate the voice synthesis unit 3 when a person approaches. There is.

Reference numeral 7 denotes a BGM sound source such as a tape recorder equipped with an endless tape or a cable broadcast, and is inputted to a BGM input section 8 provided in the main body 1 of the performance apparatus.

The audio signals output from the audio synthesis section 3 and the BGM input section 8 are sent to the respective volume adjustment sections 9 and 1.
0 to the mixer unit 11, the mixer unit 11 mixes both the BGM and the audio information, and the mixed audio signal operates the flat speaker 13 via the speaker amplifier 12. It is configured as follows. Further, a control signal is input from the control section 4 to the mixer section 11, and the mixer section 11 is configured to lower the volume level of BGM while the voice synthesis section 3 is operating.

Although not shown, on the outer surface of the main body 1 of the performance device, there are provided a mounting opening for the IC cassette 2, adjustment knobs for the volume adjustment sections 9 and 10, and a setting for the volume reduction level of BGM when the voice synthesis section 3 is activated. A knob, a volume adjustment knob for the speaker amplifier 12, etc. are arranged.

Further, on the surface of the flat speaker 13, visual information related to the audio information to be played, such as posters, pictures, and letters, is displayed.

In the above configuration, when there is no person within the detection area by the sensor 5, only the audio signal from the BGM sound source 7 is inputted to the speaker amplifier 12 via the mixer section 11, where it is amplified and BGM is played from the flat speaker 13. be done. Note that the volume adjustment section 10 protects the internal circuit when an excessive audio signal is input from the external BGM sound source 7.

When a person enters the detection area of the sensor 5 while BGM is being played in this way, an activation signal is output from the control unit 4 to the voice synthesis unit 3 based on the detection signal of the sensor 55, and the voice synthesis unit 3 is working
An audio signal is synthesized from the audio information recorded in the IC cassette 2 and output to the mixer section 11. Then, this mixer section 11 mixes it with the BGM audio signal and inputs it to the speaker amplifier 12.
Amplified audio information and BGM are sent to the flat speaker 13
It is played from At this time, since the control unit 4 outputs a signal to the mixer unit 11 to reduce the volume level of the BGM, as shown in FIG.
While the audio information is being played, the volume of the BGM is lowered. Therefore, the audio information can be heard clearly without being interfered with by the BGM, and since the BGM is played at a low volume, the noise specific to speech synthesis is erased by the BGM, so the audio information can be heard clearly. The sound quality has improved and you can listen comfortably.

Furthermore, a flat speaker 1 on which audio information is played
3, since visual information related to audio information is displayed, more persuasive information transmission is possible.

Incidentally, in the above embodiment, an example was shown in which the speaker amplifier 12 was built into the main body 1 of the performance apparatus, but it may be provided separately. Further, although an example has been shown in which the BGM sound source 7 is separate from the performance device main body 1, a tape recorder or the like may be provided integrally.

(Effects of the invention) According to the audio information automatic performance device of the invention, as described above, when a person approaches while BGM is being played, the sensor detects the sound and the sound is recorded from the flat speaker to the IC cassette. The information is played automatically to ensure that the audio information is transmitted to people, and the volume level of the background music is lowered so that the audio information can be heard clearly. Moreover,
Since the background music is played at a low volume without interruption, the noise that is typical of synthesized voices is less noticeable, allowing information to be conveyed with clear audio. moreover,
By simply replacing the IC cassette or rewriting the audio information, you can synthesize any audio information with BGM and play it. Also, EPROM is stored in the IC cassette.
, the audio information can be easily rewritten. Furthermore, since flat speakers are used, they can be combined with visual information by pasting posters or writing pictures or text on their surfaces, which can further enhance the information transmission effect and have great effects.
