PURPOSE: A package for converting an acoustic signal into an electric signal is provided to freely choose a direction for being mounted by additionally arranging electric connecting pads on both sides of a PCB(Printed Circuit Board) for an element, which converts an acoustic signal into an electric signal, and a PCB(Printed Circuit Board) for a circuit set, which processes an signal. CONSTITUTION: A PCB(Printed Circuit Board) for an element converting an acoustic signal into an electric signal(160) includes an acoustic inlet. A PCB for a circuit set processing an signal(140) is arranged up or down facing the PCB for an element converting an acoustic signal into an electric signal. The element converting an acoustic signal into an electric signal is arranged inside the acoustic inlet of the PCB for an element converting an acoustic signal into an electric signal. The PCB for a circuit set processing an signal is electrically connected to the element converting an acoustic signal into an electric signal. A chamber forming frame(150) separates a chamber space from outside. |
