Abstract: Disclosed is a high power micro-speaker having a damper plate. More particularly, disclosed is a high power micro-speaker in which a damper plate has an opening through which a voice coil can pass, and the voice coil having passed through the opening is attached to a lower surface of a vibrating plate that is located above the damper plate, which provides an increased vibrating region. As such, enhanced output power of the micro-speaker is accomplished by increasing a height of the voice coil, or a slimmer design of the micro-speaker is accomplished by reducing a height of a frame.

Abstract: Disclosed is a microspeaker with an inner resonance chamber, more particularly a microspeaker with an inner resonance chamber which improves quality of sound and enables slim and compact design of the microspeaker by blocking rearward sound generated at the rear side of the vibration plate to prevent interference of a rearward sound with a forward sound generated at the front side of a vibration plate and installing a chamber with a specific volume within the microspeaker to allow the rearward sound to cause resonance.

Abstract: Disclosed is a micro speaker module capable of reducing the thickness of an enclosure that supports a micro speaker. The enclosure of the disclosed micro speaker module includes a first frame having a supporting portion configured to support the micro speaker, and a second frame configured to cover an open side of the first frame. A first cover and a second cover are respectively insert injection molded with or attached to portions of the first frame and the second frame corresponding to the micro speaker that is supported by the supporting portion, which results in a reduction in the thickness of each frame.
