The rocking of the loudspeaker diaphragm is a severe problem in headphones, micro-speakers and other kinds of loudspeakers causing voice coil rubbing which limits the maximum acoustical output at low frequencies. The root causes of this problem are small irregularities in the circumferential distribution of the stiffness, mass and magnetic field in the gap. A dynamic model describing the mechanism governing rocking modes is presented and a suitable structure for the separation and…

Room Modal Equalisation with Electroacoustic Absorbers
The sound quality in a room is of fundamental importance for both recording and reproducing processes. Because of the room modes, the distributions in space and frequency of the sound field are…
Extensions to the Mode Matching Method for Horn Loudspeaker Simulation
TLDR
The Mode Matching Method is extended to new cases closer to real-world applications, and the use of the method to compute the transfer function and resonance frequencies of non-shoebox shaped rooms is used.
