Abstract
The invention discloses an acousto-optic audio signal cable which includes an audio wire cluster, at least one LED marquee light wire or at least one illuminating line parallel or spiral twining around outside or external wall of the audio wire cluster and an acousto-optic controller. The audio wire cluster and the LED marquee light wires form a cluster which is coated by a transparent insulating layer. A main circuit board of the acousto-optic controller includes a sampling amplifier circuit component, an analog-digital conversion circuit component, a microprocessor and an output driver sequentially connected. The audio wire cluster is connected to the input end of the sampling amplifier circuit component. The LED marquee light wires are connected to the output driver. The acousto-optic audio signal cable is simple in structure, convenient to operate, dynamic, fashionable and capable of synchronously flickering light during tone and rhythm changes of instrumental performances and speeches.
