A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axis of the two coils.
coded in Matlab both for experimental and simulated FRFs. Another advantage of the stepped frequency domain analysis was the possibility of taking into account variations of the voice coil impedance with respect to the
This project was a part of my internship at Texas Instruments, Bangalore. Aim of the project is to simulate the exact behavior of a microspeaker in terms of Sound Pressure Level (SPL), excursion of voice coil and Temperature of voice coil. Microspeaker modelling was done in two parts i.e. Thermal modelling and Electromechanical modelling.
