Claim:
1. An electro-acoustic transducer, comprising: a base; and a plurality of vibration portions, wherein each of the vibration portions comprises a piezoelectric transduction layer and has two connection ends and a free end, the connection ends are connected to the base, the free ends are separated from one another, the piezoelectric transduction layers are adapted to receive electrical signals to deform, such that the vibration portions are driven to vibrate and generate corresponding acoustic waves, and the vibration portions are adapted to receive acoustic waves to vibrate, such that the piezoelectric transduction layers are driven to deform and generate corresponding electrical signals, wherein the base has an opening, the vibration portions are located in the opening, the connection ends are connected to an inner edge of the opening, and a notch is provided between each of the vibration portions and the inner edge of the opening, and the notch is located between the two connection ends.
