Micro speaker

The present invention relates to a micro speaker. Particularly, the present invention relates to a micro speaker in which when disassembling a protecting cover and a frame from each other, internal components are prevented from being damaged, an unnecessary squandering of resources is avoided, and an occurrence of a short circuit formation is also prevented during the installation of the speaker unit. A micro speaker is disclosed. An oscillating plate is secured to the bottom of a protecting cover, and a terminal is installed on a side of the protecting cover, the terminal being electrically connected to a voice coil. A magnetic circuit is secured into a recess of a frame, and the protecting cover is attached on the top of the frame. Accordingly, when disassembling the speaker unit, any damage of the oscillating plate can be excluded. Further, when grounding the terminal to a circuit board, the connecting portion of the terminal is prevented from forming a short circuit.
