The invention discloses a plane loudspeaker monomer and a planar loudspeaker device. Flat speaker unit by the first hole, second hole electrode and the electrode in including diaphragm electret layer and the electrode layer of the composition, the formation of the air gap between the first and the second hole electrode and diaphragm. In one embodiment, a plurality of supports may be added to be disposed between the first and second aperture electrodes and the diaphragm. In one embodiment, a planar loudspeaker device is provided having at least two planar speakers stacked on a single body. In one embodiment, both ends of the signal source are respectively and electrically connected to the first and second electrode holes, or in another embodiment, one end of the signal source is electrically connected to the first and the second hole electrode, and the other end of the signal source is electrically connected to the diaphragm, so that electret vibrating the vibration of the membrane layer flat speaker unit to produce sound, low distortion (Low? THD) effect.
