Description

[Detailed description of the invention] The present invention relates to viewing devices for baseball stadiums, theaters, etc.

When it comes to baseball or theater, you don't just watch the game or play; at the same time, when it comes to baseball, you get to explain the details of the game, the current situation of the players and teams, and when it comes to theater, you get to explain the historical background of the play, the characters, etc. It's more fun if you get it.

At baseball stadiums, etc., we sometimes see people bringing radios and other equipment into the bleachers, but this is limited to when live broadcasts are being made of the game; much less live broadcasts are rarely made in the case of plays. Not yet.

Even if a live broadcast is being carried out, even if you bring a radio into the bleachers, it may be difficult to receive it due to interference from other radio waves or the influence of the structures that make up baseball stadiums, theaters, etc. Moreover, not only is the number of people who can listen to it limited, but it can also cause trouble to nearby viewers.

In view of these conventional inconveniences, the present invention was developed not only for baseball, soccer, and other sports, but also for people who are outside the baseball field, theater, theater, etc., as well as those inside the venue. At the same time, we can provide unique explanations of baseball or plays to as many spectators as possible without causing any inconvenience to nearby spectators (for example, at a baseball stadium, we can provide information on the details of the game, players, teams, etc.) It is an object of the present invention to provide a viewing device for a baseball stadium, etc., which allows the audience to easily and reliably listen to the commentary) while sitting in the bleachers.

Hereinafter, an example of implementing the present invention will be described based on the drawings.
A in the figure is a public address room, which is set at a predetermined location such as a baseball stadium or theater hall.

In this public address room A, an audio signal generator 1 and a magnetic wave transmitter 2 are installed.

The audio signal generator 1 is for converting audio into an audio signal, and refers to a microphone or a tape recorder, and a magnetic wave generator 2 is electrically connected to the audio signal generator 1.

The magnetic wave transmitting device 2 is for converting the audio signal from the audio signal generating device 1 into audio magnetic waves and sending audio current to the loop antenna 4. Connect 4.

The loop antenna 4 is used to oscillate the audio magnetic waves amplified by the magnetic wave reinforcing wire ring 3 to the bleachers B, and generate a magnetic field 6 of the audio magnetic waves, and is intended to generate a magnetic field 6 of the audio magnetic waves in the air above the bleachers B, or on the ground or under the feet of the bleachers B. The loop antennas 4 are spread around the ground and installed in response to the site so that the magnetic wave receiving devices 5 installed on each seat C of the bleachers B can easily receive the acoustic magnetic waves oscillated from the loop antenna 4.

The magnetic wave receiving device 5 is for receiving audio magnetic waves oscillated from the loop antenna 4, and is composed of a magnetic wave receiving wire ring 7 and a magnetic wave strengthening receiving wire ring 8, and is arranged for each seat C of the bleachers B or for each seat C. 1 to 4 earphones 9 are detachably connected to the magnetic wave receiving device 5.

Of course, the magnetic wave receiving device 5 may be equipped with a volume adjustment device so that the volume can be adjusted appropriately according to the tastes of the viewers and listeners.

In this way, the present invention installs an audio signal generator in a public address room and a magnetic wave transmitter that converts the audio signal from the audio signal generator into audio magnetic waves, and causes the magnetic wave transmitter to oscillate audio magnetic waves. A loop antenna is connected, the loop antenna is stretched around the bleachers, a magnetic wave receiving device is installed in the bleachers to receive audio magnetic waves from the loop antenna, and earphones are connected to the magnetic wave receiving device. Broadcasting commentary, original commentary (for example, detailed information about the game, players, teams, etc. at a baseball stadium) or music, etc. from the public address room of the baseball stadium or theater when watching a play or play. This allows as many viewers as desired to listen easily and reliably while sitting in the audience seats, and also allows those who do not want to listen to the original explanations even though they are in the same viewing area, It is possible to make the viewing experience more enjoyable without causing any inconvenience to the spectator seats (viewers) who do not have the facilities.

Furthermore, since the device according to the present invention uses audio magnetic waves,
It is not subject to any regulations under the so-called Radio Law, and as a result, the device is easy to assemble and install, and there is also the risk of causing radio wave interference outside the baseball stadium or theater, or conversely receiving radio wave interference from outside the stadium. It can be installed anywhere you want.

Therefore, it is an optimal device to be installed in the entire baseball stadium or theater, or in a limited area (section) within the stadium.

Therefore, the intended purpose can be achieved.
