Abstract
A loudspeaker has voice coil suspended in the gap of a frame and motor by a spider and cone. The spider is attached to the frame by a clamp. The frame has a pair of contact pads formed therein. First and second retainers on the frame and clamp are releasably engageable through a combined axial and rotational movement. The clamp when engaged holds the periphery of the spider against the frame and the leads of the voice coil against the contacts pads. Cam surfaces on the retainers create axial pressure to hold the spider against the frame.
Claims26
A loudspeaker, comprising:
- a frame including at least one first retainer fixed thereto;
- a motor attached to the frame, the motor and frame defining a gap and an axis;
- a voice coil disposed partially in the gap;
- a spider connected to the voice coil;
- a cone connected to the voice coil;
- a surround connected to the cone and attached to the frame;
- and
- a clamp having at least one second retainer formed thereon, the first and second retainers being axially movable relative to one another between a released position and an adjacent position when the retainers are arranged in a first, spaced relative rotational orientation, and the first and second retainers when in the adjacent position being rotationally movable about said axis between said first, spaced relative rotational orientation and a second, aligned relative rotational orientation wherein the retainers engage one another to prevent relative axial movement between them, the clamp at least when in said second relative rotational orientation engaging at least a portion of the periphery of the spider to removably attach the spider to the frame.
