Electroacoustic transduction fire extinguisher

Abstract

The invention provides an electroacoustic transducing fire extinguisher, which relates to the technical field of fire fighting and fire extinguishing. The electroacoustic transducing fire extinguisher includes a signal generator, a power amplifier, an electroacoustic transducer, an acoustic waveguide and an energy gathering part; a signal generator, a power The amplifier and the electro-acoustic transducer are electrically connected in turn; the signal generator is used to generate low-frequency AC analog electrical signals; the power amplifier is used to amplify low-frequency AC analog electrical signals; the electro-acoustic transducer is used to convert electrical signals into sound waves; one end of the acoustic waveguide It is connected with the electroacoustic transducer, and the other end is connected with the energy-gathering element; the energy-gathering element is provided with a through hole, and the energy-gathering element is used to generate a sound pressure gradient to enhance the output sound wave. The acoustic wind generated by the electro-acoustic transducing fire extinguisher makes the density of the air around the burning object sparsely distributed, thereby realizing fire extinguishing. The device has long service life, no pollution by using physical technology, and is economical; safe to use, has no limit to the amount of fire extinguishing substances, has wide application range, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to an electroacoustic transducing fire extinguisher. Background technique [0002] Fire is the most common disaster that seriously endangers the safety of people's lives and properties and directly affects economic development and social stability. In recent years, with the rapid development of economic construction, the sharp increase of material wealth, the extensive development and application of new materials, new energy, and new equipment, the continuous expansion of urbanization, and the improvement of people's material and cultural levels, the number of fires in cities Higher and higher, resulting in increasing personal and property losses. Fire has become one of the most frequent, most destructive and most influential disasters in China. [0003] If the correct fire extinguishing equipment can be used to control and extinguish the fire at the i...
