A MEMS speaker including a base, a circuit board, a spacing layer, a vibration mold, and at least one actuator. The base has a first chamber. The circuit board is disposed on the base, and has at least one support portion and a fixing portion disposed around the support portion. The at least one support portion has a first perforation, and a plurality of second perforations are formed between the at least one support portion and the fixing portion. The spacing layer is disposed on the circuit board. A second chamber is formed between the spacing layer and the circuit board. The vibration mold is disposed on the spacing layer. The actuator is disposed on the support portion of the circuit board. The actuator has a shift part and a deformation part disposed above the first perforation of the support portion. The second perforations communicate with the first chamber and the second chamber.
