Abstract: A speaker is provided. The speaker includes a housing. The speaker also includes a first diaphragm plate positioned within the housing and comprising a first driving device forming an exterior surface of the first diaphragm plate. The speaker further includes a second diaphragm plate positioned within the housing and comprising a second driving device forming an exterior surface of the second diaphragm plate. In addition, the speaker includes an insert plate fixedly attached to the housing and positioned between the first diaphragm plate and the second diaphragm plate. The insert plate includes an insert plate driving device positioned adjacent the first driving device and the second driving device. The insert plate driving device is configured to interact with the first driving device to move the first diaphragm plate relative to the housing and interact with the second driving device to move the second diaphragm plate relative to the housing.

Abstract: A speaker includes a frame, a magnetic circuit and a deflectable diaphragm. The frame supports the magnetic circuit and the deflectable diaphragm. The magnetic circuit includes a yoke, permanent magnet, top plate and a voice coil former. The voice coil former includes a voice coil wrapped around a lower portion of the perimeter. In an embodiment, an inner wall of T-Yoke forms a through hole along the height of the T-Yoke. A lead wire fixture is positioned at least partially within the through hole. The lead wire fixture includes a cable that is spliced or stripped into one or more lead wires that electrically couples with the voice coil. In an embodiment, the cable, the lead wire fixture, and the lead wires are pre-assembled or integrated into a component. This integration helps to reduce the height and width of the speaker and helps to create a more compact speaker.

Abstract: The present invention relates generally to a compact speaker which includes a diaphragm with an embedded voice coil on the surface of the diaphragm, and a magnet, secured in a frame. Due to the placement and orientation of the voice coil, the improved transducer is compact, easy to manufacture, robust and efficient.
