Abstract

This invention provides an audio speaker with improved physical safety isolation between a voice coil and other electrically live elements.

Claims (7)

1. A speaker comprising:
(a) electrical elements that are electrically live when the speaker is in use, the electrical elements including a voice coil;
(b) moving elements that move in response to an audio signal received by the voice coil, wherein the moving elements include a diaphragm; and (c) an isolation barrier mounted between the voice coil and the diaphragm.
2. The speaker of claim 1 wherein the voice coil is formed on a voice coil former and wherein the isolation barrier includes a central barrier mounted within the voice coil former and an lateral barrier mounted outside the voice coil former.
3. The speaker of claim 1 wherein the isolation barrier includes a barrier flange extending laterally from the side of speaker.
4. The speaker of claim 1 further comprising a basket barrier.
5. The speaker of claim 1 further comprising a canister barrier.
6. The speaker of any one of claims 1 to 5 further comprising an amplifier within the speaker.
7. A speaker assembly comprising a speaker housing, an amplifier and a speaker according to any one of claims 1 to 5.
