aluminium voice coil

Apr 15, 2012· I've recently been checking out some higher end cans and some (I can't remember which) contain aluminum voice coils. This seems slightly strange, since aluminum is definitely not as good of a conductor as copper or silver, and given that the voice coil is designed to create and respond to a magnetic field, it seems like an aluminum voice coil would do a poorer job, even after considering its

Overview

Mar 08, 2009· Copper doesn't last longer. The main difference is you will have a longer winding on the coil with aluminum than copper to acheive the same thermal potential. Copper will give a little stronger BL (motor strength) and is a better conductor of electricity. BUT aluminum weighs 1/2 of what copper does and handles heat better.

Copper-clad aluminium wire. Copper-clad aluminium wire (CCAW or CCA) is an electrical conductor composed of an inner aluminium core and outer copper cladding Uses. The primary applications of this conductor revolve around weight reduction requirements. such as the voice coils in headphones or portable loudspeakers; high frequency coaxial

The need to increase the thickness of aluminum wire is a consideration in its use in tight voice coil gaps—especially as it expands more than copper voice coils when hot. So, this wonder wire is lighter than copper, has a current-carrying capacity several orders of magnitude higher than copper, and behaves more linearly at high power.

The voice-coil is the part of the speaker that the output of the amplifier is directly fed to, and they get hot when driven hard. As amps began to get drastically more powerful, folks started to look for another material to wind the voice-coil on; one that could take a lot more heat.

actually - and I don't know why - brass was often used in the old days for voice coils in woofers and extended range drivers. Aluminum was also common, probably because on a per dollar as well as on a a per gram of mass basis, its conductivity is very high. Copper's a good default, though.

voice coil, has the most effect on the impedance of the voice coil than other ring configurations that are used. Because of this and since this document is on the effect of shorting ring on voice coil impedance, the shorting ring investigated here will be of this kind. Understanding the working of such case of a shorting ring, will also lead to
