AA loud speaker cone is connected to a AC signal genetator.When the frequency of the signal genetor is alterned the amplitude of the cone changes.why?
My working: As the frequency increases the amplitude decreases because there is less change in the magnetic flux and vice versia....I am a bit confused about the relationship between the amplitude and frequency... can you please give me some scientific evidence to lead me in the correct path.Any help would highly be appriciated

Also, mechanical resonances, often represented by Bessel functions, vary (nonlinearly?) the efficiency of the cone surface with repect to frequency.
