Can Speakers Emit Directional Sound?
Traditional speakers
These types of speakers come in all shapes and sizes, but one thing is consistent throughout their design – and that’s how they function. Generally speaking, they work via the transmission of electricity through the conical cylinder inside of the speaker, which reverberates back and forth, causing air pressure to emit sound based on the specific noise that is being emitted from the speaker.
Directional speakers
Doing all of the above and more, directional speakers like those available at https://www.focusonics.com are far more modernised and versatile, often being implemented within:
- 5D cinemas
- Theatres
- Gig stages
- Museums
- Art galleries
- Retail and Showrooms
They can also be used at home and are very affordable considering the unique features that they offer.
How do directional speakers work?
Not only do these types of speakers emit noise using the tried and tested method that’s present within traditional speakers, but they also feature the same coil, but with the addition of a unique technology. This tech allows the cone to pivot inside of the speaker itself. This is done via a moving electromagnetic cone and coil, which work together to literally send sound in a particular direction.
By doing this, it can be possible to eliminate sound coming from one location and send it somewhere else; creating the acoustic illusion of the noise coming from a separate location. This ability to ‘throw’ noise is especially impressive when paired with a home cinema, as a whisper from behind the viewer can sound hyper-realistic, allowing them an extra level of immersion into the visual that they are watching.
Likewise, the sound is capable of travelling over great distances, depending on the output of the speaker itself. It’s possible to sync or wire a variety of these speakers to produce a completely controllable area where the sound can be programmed as needed. As you might imagine, this is incredibly appealing for an immersive experience and it’s just one reason why 5D cinemas and entertainment facilities are making use of this type of audio technology.
