Abstract: An electrostatic loudspeaker with multichannel output includes an electrostatic diaphragm, spacers, a first electrode plate and a second electrode plate. The electrostatic diaphragm has two outer surfaces, and a spacer is disposed on each outer surface. The spacers and the electrostatic diaphragm are sandwiched between the first and second electrode plates. At least two metal layers that do not overlap each other are respectively disposed on each of the first and the second electrode plates, and are electrically connected to at least two different electric contacts respectively, so as to obtain at least two corresponding sound source signals. In this manner, at least two metal layers attract or repel the electrostatic diaphragm, causing the electrostatic diaphragm to vibrate and generate sound respectively. In this presentation, at least two sound source signals may be applied to the same electrostatic loudspeaker, thereby achieving the objective of multichannel output.
