Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] Regarding a system for giving a description of each exhibit by voice, a description voice can be activated by a switch for each exhibit, and in the case of a group tour, a guide gives an arbitrary description voice. In order to be able to easily start up, an audio playback device which is pre-recorded with a description of the exhibit and which is arranged in the vicinity of the exhibit corresponding to each exhibit, and a manual wireless communication device which activates the playback device. And a portable wireless switch which can be used in common by the plurality of audio reproducing devices and is portable.

〔Technical field〕

The present invention relates to a system in which a plurality of exhibits are displayed in one room, and a description of each exhibit is provided by voice.

(Prior art)

It is publicly known that a description is recorded by voice for each exhibit and that the viewer reproduces the description by voice by operating a corresponding switch.

It is also known to provide an approach detection switch and automatically reproduce an explanation sound when a person approaches.

[Conventional problems]

In the automatic reproduction method using the proximity detection switch, when a plurality of visitors approach a plurality of exhibits, a plurality of explanation sounds are reproduced at the same time, and when the adjacent interval is small, the explanation is difficult to hear.

Although there is no such problem in the method of starting with a manual switch, the switch and the sound reproducing device are generally wired, which not only has an aesthetic problem, but also when a group visit or the like, the guide is switched by the guide. It is inconvenient because it is necessary to operate each and every time. Normally, it is preferable that the visitor stand near the exhibit and the guide is at the back, but the wired switch as described above is usually installed very close to the exhibit, and the guide is set to the switch. It is necessary to be located near the position, which is not preferable. In addition, the flow lines of visitors and guides when moving from exhibit to exhibit are also inappropriate.

An object of the present invention is to solve all the above problems.

[Means for solving the problem]

According to the present invention, a wireless connection is provided between the audio playback device and the switch of each exhibit, that is, a wireless switch is employed, and a guide switch carries the wireless switch.

[Action]

By operating the wireless switch corresponding to each exhibit by using the wireless switch, the visitor can arbitrarily reproduce and start the description of the desired exhibit as in the case of the wired, and at the same time provide guidance The user can also activate the sound reproducing device arbitrarily even if he / she is behind the visitor by the wireless switch.

In other words, by making the switches wireless, it becomes possible for the switches for each exhibit to coexist with the common switches possessed by the guide.

〔Example〕

FIG. 1 is a block diagram of an embodiment of the present invention, wherein 1A to 1N are located in the vicinity of the exhibit corresponding to each exhibit, and 2A to 2N are arranged in the vicinity of the exhibit corresponding to each exhibit, and a description regarding the corresponding exhibit is sound-based in advance. , 3A to 3N are wireless switches for activating the corresponding sound reproducing devices, and 3X is a common wireless switch that is portable and can be used in common for all sound reproducing devices.

As the audio reproducing devices 2A to 2N, various devices such as a cassette tape recorder and a device using a ROM (read only memory) and a DA converter can be used.

As the wireless switches 3A to 3X, various modulation systems using infrared rays or microwaves can be used.

In addition, in order to simplify the structure of these hardware and reduce cost, reliability and size, it is necessary to configure the system so that once activated, audio playback cannot be interrupted and audio playback continues for a certain period of time. it can.

The wireless switches 3A to 3N for each exhibit are placed near each exhibit, but need not be fixed,
The layout is free according to the exhibits because it is wireless.

The common wireless switch 3X may be exactly the same as 3A to 3N, and the guide can carry the wireless switches 3A to 3N corresponding to each exhibit one by one even from behind the visitor in case of a group tour. Without manipulation
A desired audio reproducing device can be started.

By limiting the directivity and effective range of each wireless switch, it is possible to prevent interference between adjacent exhibits even if the same signal channel (frequency) is used.

If the distance between adjacent exhibits is very short, the use of the same signal channel may cause interference. In that case, two types of signal channels may be prepared, and different channels may be used for adjacent exhibits.

In that case, it is preferable that the common wireless switch 3X be capable of transmitting both signal channels. FIG. 2 is a block diagram of an embodiment in that case,
31 and 32 are switches for each channel, 33 and 34 are carrier frequency generators for each channel, 35 is a battery power supply, and 36 is a light emitting element using infrared rays or the like.

〔The invention's effect〕

As described above, in the present invention, an individual switch is provided for each exhibit, and the guide carries a common switch,
By setting these switches as wireless switches (because the receiving part of the sound reproducing device can be received independently of the individual / common switch), even in the case of a group tour, the guide operates the common switch to disturb the visitor. It becomes possible to activate the audio reproducing apparatus without the delay.

[Brief description of the drawings]

FIG. 1 is a block diagram of one embodiment of the present invention, and FIG. 2 is a block diagram of one embodiment of a wireless switch. In the figure, 1A to 1N are exhibits, 2A to 2N are audio playback devices, 3A to 3N
Is a wireless switch, and 3X is a portable wireless switch.
