Abstract
A microphone structure is provided. The structure includes a microphone chip, at least a first metal pad on one surface of the microphone chip, a circuit element, and at least a second metal pad on one surface of the circuit element. The surface with the first metal pad of the microphone chip and the surface with the second metal pad of the circuit element face to each other, and connect to each other by the first metal pad and the second metal pad. Because the microphone chip connects to the circuit element without conducting wires, the parasitic capacitance effect caused by the conducting wires is reduced. The efficiency of the microphone structure is improved.
