A coil is wound around a coil former, and at least a portion of the coil is located in the magnetic gap. A connecting member is arranged on a side of the coil former close to a side wall of the accommodating cavity. An annular first damper is arranged between the coil former and the connecting member. The first damper is close to an upper end of the coil and is distal from a lower end of the coil. An annular second damper is arranged between the connecting member and the side wall of the accommodating cavity. The second damper is close to the lower end of the coil and is distal from the upper end of the coil.

Abstract: Certain aspects of the technology disclosed herein involve an apparatus and method of operation for an audio device having a perforated diaphragm. Perforations extend along a plane of the perforated diaphragm. A driver is attached to the perforated diaphragm. The driver includes a voice coil. The driver is configured to cause the perforated diaphragm to vibrate. Vibrations in areas between parallel perforations act as independent audio sources.

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.
