Zusammenfassung:	A hybrid microspeaker includes a low-frequency range speaker and a high-frequency range speaker. The low-frequency range speaker includes a frame, a low-frequency range magnetic circuit installed inside the frame, a voice coil configured to vibrate by mutual electromagnetic force with the low-frequency range magnetic circuit, and a diaphragm seated on the frame and configured to vibrate with the voice coil to generate sound. The high-frequency range speaker includes a bracket coupled to an upper portion of the frame, a high-frequency range magnetic circuit installed inside the bracket, and a flexible printed circuit board (FPCB) seated on the bracket and including a pattern configured to vibrate by mutual electromagnetic force with the high-frequency range magnetic circuit to generate sound.
