The invention relates to a film speaker array, which comprises a piezoelectric electret film and a circuit board assembly, wherein the piezoelectric electret film is a porous polymer film, and electrode arrays are respectively and correspondingly arranged on two sides of the piezoelectric electret film; a speaker circuit, and a circuit board input end and a circuit board output end which are electrically connected with a speaker circuit are arranged on the circuit board assembly, and the circuit board output end is electrically connected with electrode arrays arranged on two sides of the piezoelectric electret film. The film speaker array made of porous polymer film is integrated with the advantage of high directivity of the speaker array and the advantages of lightness, thinness, softness, simple structure, high reliability and low cost of the polymer piezoelectric electret, and greatly expands the application range of the speaker array, thereby being an alternative replacing the traditional speaker array in the theater, the meeting place, the classroom, the museum, the gymnasium and other circumstances.
