    Abstract: A passive radiator structure includes an integrally formed diaphragm structure and a surround suspension. The diaphragm structure includes a diaphragm, a frame, and a web-like spider having a plurality of suspension arms integrally extended to between the diaphragm and the frame. The surround suspension has a radially inner gluing edge adhered to a radially inner location of the diaphragm structure around the diaphragm, and a radially outer gluing edge adhered to a radially outer location of the diaphragm structure around the frame. The surround suspension and the web-like spider of the diaphragm structure form two suspension elements for stably supporting the diaphragm, enabling minimized irregular shaking and reduced weight of the diaphragm, as well as reduced sound distortion, increased compliance and upgraded efficiency of the passive radiator structure.

    Abstract: A vibrating element including a diaphragm, a voice coil and a stiffening layer is provided. The diaphragm has a first surface and a second surface opposite to each other. The first surface includes a first conductive region and a second conductive region. The voice coil is disposed on the first surface. Two ends of the voice coil are electrically connected to the first conductive region and the second conductive region. The stiffening layer is disposed on the diaphragm. The diaphragm has a center region, which is enclosed and circled by the voice coil and includes an area of the diaphragm above the voice coil. The region outside the center region includes an inner circled zone and an outer circled zone surrounding the inner circled zone. At least one end of the voice coil is located in the inner circled zone and the stiffening layer covers the inner circled zone.
