Abstract
A design method of mine-used sound box was introduced. A selection method of loudspeaker in mine-used sound box was introduced firstly from aspects of three parameters of frequency characteristics, distortion degree and impedance. Then cavity volume of mine-used sound box was calculated by taking balanced frequency response as a design goal. Finally, structures of size and material of mine-used sound box were designed.
