The electrical impedance of the speaker varies with the back EMF and thus with the applied frequency. The impedance is at its maximum at F s, shown as Z max in the graph. For frequencies just below resonance, the impedance rises rapidly as the frequency increases towards F s and is inductive in nature.
It needs to be kept in mind that most loudspeakers have an impedance that varies considerably with frequency. [6] [9] For a dynamic loudspeaker driver, a peak in the impedance is present at the free-air resonance frequency of the driver, which can be significantly greater in magnitude than the nominal rated impedance. In addition, the ...
Most modern quality amplifiers have >110 dB dynamic range, [7] which approaches that of the human ear, usually taken as around 130 dB. See Programme levels. Phase distortion, Group delay, and Phase delay A perfect audio component will maintain the phase coherency of a signal over the full range of frequencies. Phase distortion can be extremely ...
All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1255 ahead. Let's start with a few hints.
The main effect of is on the impedance of the driver, with high drivers displaying a higher impedance peak. One predictor for low Q m s {\displaystyle Q_{\rm {ms}}} is a metallic voice-coil former. These act as eddy-current brakes and increase damping, reducing Q m s {\displaystyle Q_{\rm {ms}}} .
