Abstract
An audio transducer includes a frame, a magnet coupled to the frame, and a voice coil axially aligned with the magnet. The voice coil can be configured to receive a flow of electric signals from an amplifier, and, in response to the received flow of electric signals, correspondingly move a diaphragm toward or away from the magnet. The audio transducer can further include a collar coupled to the voice coil. The collar can have a flange extending radially outwardly from the voice coil. The audio transducer can further include a spider having a radially outer portion coupled to the frame and a radially inner portion coupled to the flange of the collar.
