Directional Speaker B for confidential public intercoms

What are directional speakers and how do they work?

Directional speakers, also called parametric or ultrasonic speakers, use patented technology to project sound in a focused beam similar to how a flashlight focuses light. Our Speakers B emit ultrasonic waves that demodulate in the air to create audible sound only within a specific targeted area. With computing capacity of 2.4 billion operations per second, we have integrated patented digital signal processing software to make the sound as clear and loud as possible with zero background noise.

How do directional speakers differ from regular speakers?

Traditional speakers disperse sound in all directions, creating a wide sound field that everyone nearby can hear. Directional speakers project sound in a straight beam, so only people standing within the targeted area can hear the audio while others nearby experience silence. This eliminates noise pollution and creates personalised audio zones.

What are the frequency response limitations of directional speakers?

Directional speakers excel at mid-to-high frequency reproduction (typically 200Hz-20kHz), making them ideal for speech, ambient sounds, and most musical content. Bass frequencies below 200Hz are less directional due to the physics of sound wave propagation - longer wavelengths naturally spread more than shorter ones.

How far can directional speakers project sound effectively?

Our Directional Speaker B typically provides clear audio projection up to 10 meters in optimal conditions. Sound quality remains excellent within the first 5 meters, with gradual decrease beyond that range. Factors like ambient noise, mounting height, and listener positioning affect the practical range.

Can directional speakers produce stereo sound?

Yes, stereo sound is possible by using two Directional Speaker B units focused on the same listening area. This creates a stereo sound field within the targeted zone while maintaining the directional properties that prevent sound leakage to surrounding areas.

How many speakers do I need for my space?

Generally, one speaker per person is required for optimal audio delivery. Each speaker creates a focused audio zone for individual listeners. For larger groups, multiple speakers can be positioned and chained together to cover the desired listening areas without interference.

Do directional speakers work in noisy environments?

Yes, directional speakers perform well in ambient noise conditions. The focused beam delivers audio directly to the intended listener, cutting through background noise more effectively than traditional speakers. Our boost mode feature can be activated in particularly noisy environments to enhance audio clarity and volume within the targeted area. Samsung successfully deployed our speakers at Paris Gare de Lyon train station, broadcasting intelligible audio from 6 meters high despite the noisy station environment.

How difficult is it to install directional speakers?

Installation is straightforward and similar to mounting traditional speakers. As a compact 260 × 260 × 32 mm device weighing 1 kg, the Directional Speaker B fits standard VESA 100 mounting systems. You need access to power (standard electrical connection) and an audio source (3.5mm jack, optical cable, or other standard audio input).

What mounting options are available?

We provide screw mounts for permanent installations and clamp mounts for temporary or adjustable setups. The speaker can also be attached to any standard VESA 100 mounting hardware. Ceiling mounting integration is also available for installations requiring complete aesthetic integration. While the optimal "sound shower" position (mounted overhead and angled downward) delivers the best results, other mounting configurations are possible depending on your space requirements. Tell us your specific needs and we will find the right mounting solution for your installation.

How are directional speakers used in retail environments?

In retail, directional speakers enhance point-of-sale displays, provide product information without disturbing other shoppers, create ambient soundscapes for specific store sections, and deliver targeted promotional messages. The presence detector feature can activate audio only when customers are nearby, reducing energy usage and noise pollution. IKEA uses our speakers to deliver content in specific store zones without adding noise to surrounding areas, while Comptoir de l'Ours integrated our speakers with digital signage displays to unmute TV screens without sound leaking throughout their showroom.

What makes directional speakers ideal for museums?

Museums benefit from directional speakers because they preserve the quiet, contemplative atmosphere while providing rich audio content. Visitors can hear detailed information about specific exhibits without disturbing others nearby. This eliminates the need for shared headphones, improving hygiene and reducing maintenance requirements. La Cité de l'Architecture uses our speakers to provide targeted sound experiences for their exhibitions without using headphones, while CosmoCaixa Science Museum in Barcelona delivers focused audio for each exhibit zone without creating overlap or disturbing nearby areas. Maison Gainsbourg in Paris integrated our speakers into ceiling construction to create personal, immersive sound zones within their museum hallways.

Can the beam width be adjusted?

Yes, our Directional Speaker B offers three different beam width settings, allowing you to customise the coverage area for your specific application. This adjustable beam width is a unique competitive advantage that provides flexibility for different space configurations and listener requirements. You can choose narrow focus for precise targeting or wider coverage for areas with more listener movement.

How does Directional Speaker B compare to competitors?

Our speaker delivers superior directional performance with practical installation flexibility that competitors often lack. Our R&D team testing shows Speaker B achieves the tightest beam control, while maintaining comparable sound levels. Our compact 26×26×3.2cm form factor is significantly smaller than competitors.

Are there size or weight limitations I should consider?

Our Directional Speaker B weighs only 1kg with compact dimensions (260 × 260 × 32 mm), making it suitable for most installation scenarios. The slim profile works well in environments where aesthetic integration is important. For installations requiring complete invisibility, we also offer options where the speaker can be integrated directly into ceiling construction, as implemented at Crédit Agricole where speakers were integrated into the ceiling for customer service kiosks. Note that our speakers are designed for indoor use only and are not suitable for outdoor installations.

How does Speaker B voice mode enhance speech intelligibility?

Voice mode optimises the speaker's frequency response and processing specifically for human speech. This feature enhances clarity of spoken content, improves intelligibility in noisy environments, and reduces listening fatigue during longer presentations or announcements. It's particularly valuable for museum audio guides and retail product demonstrations.

Can Speaker B be used outside?

No, our directional speakers are designed for indoor use only and are not suitable for outdoor installations. The speakers operate within specific environmental conditions: temperature range of 0-40°C and humidity levels of 10-70% non-condensing.
