Abstract: A thin type speaker includes a casing having a top-open receiving chamber, and an electromagnet set mounted in the top-open receiving chamber and formed of a yoke, a magnet, a pole piece, and a voice coil. A vibration diaphragm is peripherally connected to the periphery of the top-open receiving chamber. The vibration diaphragm has a corrugated damper at the center thereof. The damper has a center part fixedly connected to the electromagnet set. The voice coil is disposed at one side of the vibration diaphragm facing the top-open chamber and connected to the periphery of the damper.

Abstract: A dual magnetic loop type receiver is composed of a yoke molding, a ferrite yoke, an annular magnet, a magnetic pole member, a vibration panel, a ferrite core, and a circular plate. While the receiver is operated, the annular magnet and the ferrite core and the ferrite yoke cause the receiver to produce an inner magnetic loop that interacts with the inner voice coil, and an outer magnetic loop that interacts with the outer voice coil such that the receiver generates vibration and sound.
