A sound producing package structure includes a shell and a chip. The shell includes a top structure, a bottom structure and a sidewall structure. The chip is disposed inside the shell and configured to produce an acoustic wave, wherein the chip includes a thin film structure and an actuator configured to actuate the thin film structure, and the thin film structure is substantially parallel to the top structure and the bottom structure. A first opening is formed on the sidewall structure, and the acoustic wave propagates outwards through the first opening.
