IP Ultrasonic Directional Flat-Panel Speaker System - Smart Audio Solution for Museums DSP395T + DSP395U

DSP395T + DSP395U IP Ultrasonic Directional Flat-Panel Speaker System -Smart Audio Solution for Museums

I. Solution Overview

Museums, as important venues for cultural and historical dissemination, rely heavily on the presentation of exhibitions to shape visitor experiences. Traditional sound delivery methods, such as public address systems and conventional speakers, often face challenges with sound interference and inconsistent acoustic quality across the space. With advances in technology, ultrasonic directional speakers—a novel audio delivery solution—are increasingly being adopted in museums and other public venues. Their high directivity and interference-free characteristics enable a more immersive and personalized visitor experience.

Project Requirements

● Minimized sound interference: Directional sound waves reduce audio crosstalk within exhibition halls, ensuring that sound information in different areas does not interfere with each other.

● Personalised guided experience: Visitors can selectively listen to detailed explanations of specific exhibits according to their interests.

● Enhanced vistor immersion: Precise sound localization allows visitors to feel a stronger sense of presence during their tour.

● Optimized space utilization: Directional sound propagation enables efficient use of museum space without the need for complex audio installations.

II. Directional Sound System Configuration Solution for Small Museums

Solution Configuration:

● Individual Exhibit Zones

Install a DSP395 system in front of each exhibit, directed toward the visitor standing area.

The system plays pre-recorded audio via the built-in TF card; visitors hear clear explanations when approaching the exhibit and the audio automatically mutes when they leave.

● Temporary Exhibitions or Interactive Areas

Connect temporary audio sources (e.g., guide microphones or interactive devices) via the AUX input.

Allows rapid deployment and flexible adjustment of sound coverage.

● Corridors or Transition Areas

Install on walls or ceilings to provide directional background music or guided prompts.

Prevents sound from spreading into exhibition zones, maintaining a quiet environment.

III. Integrated Network Solution: MAG6000+DSP395 System Integration

System Advantages:

When integrated with the MAG6000 network public address system, this solution enables centralized management of the museum, background music, and emergency announcements. At the same time, ultrasonic directional speakers provide precise, non-interfering explanations at individual exhibits, perfectly resolving the conflict between “area-wide” broadcasting and “point-specific” explanation within the museum.

Solution Configuration:

This solution is designed to build an intelligent, networked, and zoned public address and directional sound system for museums. Using TCP/IP as the core transmission network, the central control room is equipped with a digital IP network broadcasting host for unified management of the entire museum. In public areas such as lobbies, corridors, and rest zones, conventional background music speakers are installed to create ambiance and deliver museum-wide announcements. At key exhibit points such as core exhibits, display cases, scale models, and significant artworks, the DSP395 IP Ultrasonic Directional Flat-Panel Speaker System (DSP395U audio player + DSP395T speaker) is deployed. This setup provides highly directional audio, delivering clear and quiet explanations to visitors standing nearby while eliminating sound overlap and interference.
