Vented-Box Loudspeaker Systems Part 1: SmaU-Signal Analysis
نویسنده
چکیده
The low-frequency performance of a vented-box loudspeaker system is directly related ta a small number of easily measured system parameters. This system is a fourtharder (24-dB per octave cutoff) high-pass filter which can be adjusted ta have a wide variety of response characteristics. Enclosure lasses have a significant effect on system performance and should be taken into account when assessing or adjusting vented-box systems. The efficiency of a vented-box loudspeaker system is shawn to be quantitatively related ta system frequency response, internal losses, and enclosure size.

The Theory of Maximally Flat Loudspeaker Systems
A convenient mathematical formulation is given for the absolute lowfrequency response of an electrodynamic direct radiator loudspeaker mounted in a vented or unvented enclosure. The combined effects of speaker Q (ratio of reactance to resistance), enclosure size, and enclosure tuning are shown to control the convergence of the response curve towards ts asymptotic value. Mathematical criteria ar...
متن کاملIdentification and compensation of the electrodynamic transducer nonlinearities
Based on a simplified nonlinear lumped element model of the electrodynamic loudspeaker in either a closed or a vented cabinet, a new nonlinear controller is derived, simulated and implemented on a DSP. The Volterra series expansion, a well known functional expansion to model nonlinear systems, is used to estimate the nonlinear parameters from distortion measurements. The controller is directly ...
متن کاملLoudspeaker Distortion – Measurement and Perception Part 1: Regular distortion defined by design
A major part of the signal distortion generated by loudspeaker systems are directly related with the geometry and properties of the material used in loudspeaker design and found in all good units passing the assembling line. Those regular distortions are the result of an optimisation process giving the best compromise between perceived sound quality, maximal output, cost, weight and size. This ...
متن کاملImpedance Compensation Networks for the Lossy Voice-Coil Inductance of Loudspeaker Drivers*
A two-terminal network that is connected in series or in parallel with a circuit to cause its terminal impedance to be transformed into a desired impedance is commonly called a Zobel [1] network. In loudspeaker design a Zobel network consisting of a series resistor and capacitor connected in parallel with the voice coil of a driver has been described to compensate for the impedance rise at high...
