Abstract
The utility model provides a double-side piezoelectric ceramic loudspeaker which comprises a piezoelectric ceramic sheet, a metal vibration diaphragm, foam, an outer frame and an organic material. The loudspeaker is characterized in that the piezoelectric ceramic sheet is spliced on two sides of the metal vibration diaphragm; Ag or Ag/Pd is printed on two sides of the piezoelectric ceramic sheet so as to serve as an electrode; thin organic material layers are printed on two sides of the metal vibration diaphragm; and the foam is spliced and fixed on the outer frame, thereby facilitating vibration and vocalization. The utility model adopts double-side driving manner and has the advantages of simple structure, reasonable design and better property.
Description
Technical field
The utility model relates to loud speaker.
