  • Transfer-function Hx(f)=X(f)/U(f) between voltage and displacement Linear parameters (Thiele-Small) Nonlinear parameters Peak, rms and dc displacement Rub & Buzz analysis

Scanning mechanical vibration

  • Complex transfer function Hx(r, f) at point r on the radiator’s surface Magnitude and phase plot Animated vibration pattern Distributed mechanical parameters

Vibration analysis

  • Accumulated acceleration level AAL Modal analysis (natural frequencies, modal loss factor, mode shape) Radial and circumferential modes Rocking modes

Scanning geometry

  • Geometry of the surface in cylindrical coordinates Export in dxf, stl and other format

Material parameters of loudspeaker parts

  • Young’s E modulus Modal loss factor
