Advantages of the FPS Plane Wave Speakers as Platform Speakers


The realization of a comfortable railroad station.

Maintaining a quiet environment around the railroad station neighborhood and improved security on the platform.

  • Strong directivity
Transmits clear and accurate information to passengers without interference from the adjacent platform.

An effective counter measure against the noise problem surrounding the nearby neighborhood.


  • At a distance, the plane wave sound is clearly audible.
Even at a place with loud bacjground noise, plane wave sound is clearly audible since its footprint is small.

A person close to a speaker and a person at a distance will both hear clear and accurate sound.

  • Hardly causes acoustic feedback
Will hardly causes acoustic feedback even if a portable microphone is used on any part of the platform.


Reduction of initial and running cost

  • We can cut overhead costs since sound is generated from both sides of the speaker. Our speakers are twice as efficient as the standard cone speaker.

  • High tolerance tp water and heat.
Outdoor installation is possible, since the vibrating diaphragm is made of a waterproof material.

The vibrating diaphragm is durable in cold and hot weather. (Temperature : -22 degrees to 220 degrees).



The BM speaker series was created mainly for use in railroad stations. These speakers use the FPS Plane Wave Speaker unit FPS2030. All parts of the speaker unit are detachable by design. Assembly is done with machine screws rather than adhesives.


  Situations with the Current Platform Speaker System

When the noise from a train is high, and the current cone speakers are turned up... When the noise from a train is high, and the current cone speakers are turned down...
-everything can be heard from the surrounding neighborhood. Noise Pollution.
-it is good for the nearby neighborhood because of low noise, however, passengers will have a hard time hearing announcements.


Passengers can not immediately judge which platform the announcement is coming from.

If you have problems hearing the platform announcement, the FPS Plane Wave Speaker can improve the situation in the following ways:

  • If you have difficulty hearing the announcements clearly because of the nearby platform, the FPS Plane Wave Speakers will send a direct announcement to the passenger while minimizing the sound from the other platform.
  • When using an elevated platform, the sound waves (announcements) disburse everywhere making it difficult to hear for passengers. With the FPS Plane Wave Speakers, sound waves from other platforms will be minimized.
  • Cone speakers tend to lose its strength the further it goes, so people usually turn the volume up. The FPS Plane Wave Speakers sound waves travel in a straight line, therefore, people will be able to hear announcements from further without the voume being raised.
  • Standard cone speakers tend to have a howling effect when the microphone gets close to the speakers.
  • When it comes to covered stations, there tends to be a lot fo echo while using cone speakers. This translates into even more noise.
  • When it comes to rain, conventional cone speakers lose much of its effectiveness. The directivity of the FPS Plane Wave Speakers lets the sound waves keep its strength for a longer distance which translates into clearer sound.
  • Neighbors complain about excessive noise from the station when using cone speakers. There will be less complaints using the FPS Plane Wave Speakers because the volume will be lower due to of the directivity of the speakers.
Improvements to the Railroad Station with the introduction of the FPS Plane Wave Speaker !

Improvement example #1.
    Comfort in the station will surely improve !

  • Announcements such as incoming, outgoing and transfer information become clearer, without the mix of the next platform's announcements.
  • Announced on the platform is heard clearly. You will not be affected by background noise such as the flow of passengers and street noise around the station.

Improvement example #2.
    Security and Service to passengers will improve!

  • They will have more time to get to their train since they can hear the announcements clearly. Passengers will not have to rush into their train and the security on the platform will surely improve.

Improvement example #3.
    Producing various effects for installation & maintenance!

  • The fewer number of speakers to install and maintain translates into a lower maintenance fees compared to the conventional cone speakers.
  • FPS Plane Wave Speakers can be installed on an outdoor platform because it is water resistant.

FPS Plane Wave Speaker enables the passenger to understand the announcement with complete comfort !
