Sound absorption of a finite micro-perforated panel backed by a shunted loudspeaker.
Journal of the Acoustical Society of America, 2014Deep back cavities are usually required for micro-perforated panel (MPP) constructions to achieve good low frequency absorption. To overcome the problem, a close-box loudspeaker with a shunted circuit is proposed to substitute the back wall of the cavity

The property of ‘‘directional tone color,’’ especially characteristic of a violin [G. Weinreich, J. Acoust. Soc. Am. 101 (to be published)], consists of a directional radiation pattern which is a very strong function both of angle and of frequency.

Experiments with a loudspeaker
European Journal of Physics, 2009A common moving-coil loudspeaker is useful for learning harmonic motion. A simple optical method is used to observe free and forced oscillations of the diaphragm of a loudspeaker. With a lock-in amplifier and data-acquisition system, the frequency response of the loudspeaker and its electrical impedance are automatically recorded versus frequency. From

A loudspeaker system includes a speaker enclosure having an opening in a front wall, and a speaker manifold mounted within the speaker enclosure and communicating with the opening. The speaker manifold includes a pair of substantially parallel side walls, a back wall, and top and bottom walls, defining a manifold chamber.

In ordinary loudspeakers for the audible range, the paper cone forms the matching device between driving mechanism and air load. It is well known that the cone cannot be designed without much trial and error, as movement at the higher frequencies is very complicated.
