Directional and parametric speakers are a unique type of speaker that use ultrasonic waves to produce highly targeted, directional sound. Unlike conventional speakers that spread sound in all directions, these speakers create a narrow beam of sound that can be directed to specific areas.

The key features of directional and parametric speakers are:

• They use ultrasonic waves modulated with audio signals to generate sound. This allows them to create a focused, directional sound beam.
• They can localize sound to a targeted area, while maintaining quiet in the surrounding space. This allows for private audio zones.
• They have a more limited range compared to conventional speakers, typically 1-15 meters.
• They are used in applications like museums, retail stores, public address systems, and more to deliver targeted audio without disturbing nearby areas.

Based on the search results provided, some of the key companies that manufacture and sell directional and parametric speakers include:

• Focusonics[1][4] – A manufacturer of high-quality parametric speakers, offering models for larger (3-15m) and shorter (1-5m) operating distances.
• Panphonics[2] – A leading directional speaker manufacturer that specializes in electrostatic speaker technology.
• Audfly[2][5] – A Chinese company that produces directional speakers using ultrasonic parametric technology.
• Akoustic Arts[3] – Provides directional speaker solutions and consulting services for various applications.

So in summary, directional and parametric speakers are a specialized audio technology used to create targeted sound fields, and companies like Focusonics, Panphonics, Audfly, and Akoustic Arts are some of the key manufacturers and sellers of these products.[1][2][3][4][5]

The Catchflow SRAY is the world's smallest directional speaker that can focus sound in a narrow beam, allowing only the intended listener to hear the audio without disturbing others around them.[1][2][3][4]

Some key features of the SRAY directional speaker:

• It uses ultrasonic propagation technology to bind the audio in a unidirectional channel, similar to how a flashlight focuses light in a beam.[3]
• This allows the sound to be directed at a specific person or area, while people outside the audio beam hear nothing.[3]
• It can be used for private listening without disturbing others, such as in libraries, public spaces, or at home.[3]
• The SRAY is compact and portable, small enough to fit in the palm of your hand.[3][4]
• It has both a directional mode and an omnidirectional mode, allowing it to function as a regular speaker as well.[2][3]
• The directional speaker technology helps reduce noise-induced hearing loss compared to using headphones or earbuds.[3]

Overall, the Catchflow SRAY provides a unique and private audio experience by tightly focusing the sound output, making it useful in a variety of settings where controlling sound dispersion is important.[1][2][3][4][5]
