Abstract
The invention discloses an improving method for a rheomicrophone and the high-voltage rheomicrophone. According to the improving method for the rheomicrophone, an existing rheomicrophone with an annular sensitive layer and a rubber coupling layer is improved; specifically, piezoelectric ceramic pieces are encapsulated in grooves in one ends of elastic bases through insulation glue, and the other ends of the elastic bases are machined into circular arc surfaces; then, the elastic bases encapsulated with the piezoelectric ceramic pieces are fixed to a rheomicrophone shell through a cover plate; the elastic bases can quickly deform and quickly restore when stressed, so that the piezoelectric ceramic pieces and the elastic bases are stressed together, and thus the purpose of improving the pressure bearing capability and the impact resisting capability of the rheomicrophone is achieved. Compared with the prior art, the rheomicrophone has the advantages of being simple in structure, high in pressure bearing capability and impact resisting capability, small in size and the like.
