MUMBAI, India, Sept. 14 -- Intellectual Property India has published a patent application (202621083666 A) filed by Vishwakarma Institute Of Technology on July 08, 2026, for An Acoustic Fire Extinguishing System.

Inventors include Bhanuse, Vijaykumar; Chaudhari, Archana; Gaikwad, Jitendra; Lipte, Utkarsha Bapusaheb; Ghodke, Om Sanjay; Wattamwar, Shruti Sudhir; and Dudhe, Achal Kishor.

The application for the patent was published on September 11, 2026, under issue no. 37/2026.

Abstract: The present invention relates to an acoustic fire extinguishing system comprising a plastic enclosure body (100) forming an outer housing, an output hole for air oscillation (101) through which low-frequency acoustic waves are directed toward the flame, a fire-resistive aluminum foil coating (102) positioned over the plastic enclosure body (100) for preventing deformation or melting due to heat exposure, a magnetic 12-inch subwoofer unit (103) configured to generate high-intensity low- frequency acoustic oscillations for flame suppression, and an input wire connection (104) configured to supply amplified audio signals from an amplifier unit to the magnetic 12-inch subwoofer unit (103). The system comprises a signal generation unit, an amplification unit, and a microcontroller-based tone generator producing signals within a frequency range of 35–60 Hz. The acoustic waves disturb the flame boundary layer, restrict oxygen supply within the fire triangle, and suppress small- scale flames without chemicals, water, or physical contact, providing a non-chemical, eco-friendly, safe, low-cost, and reusable fire extinguishing system.
