Audio illuminator

摘要

The Audio Illuminator is an integrated system providing directed lighting and a public address type amplification and loudspeaker capability, under control from a remote location. The system includes a searchlight and one or more directional, high-power loudspeakers. An audio amplifier supplies drive signals to the loudspeakers in response to audio input signals received from the remote control. The system includes a power junction box for supplying power to the amplifier and the searchlight and carrying signals to and from the various components. The system may derive power from a small portable diesel generator. A gimbal mount supports the searchlight for two-directional movement (horizontal rotation and vertical tilt angle rotation) and supports the one or more loudspeakers for movement with the searchlight in at least one of the two directions. Drive motors provide two-dimensional automatic positioning in response to signals from the remote control unit. The speakers are highly directional, and the motion of the speakers together with the searchlight enables aiming both the sound and the light at a selected target. The remote control unit includes or provides a connection to a microphone, and the remote control supplies signals from the microphone to the audio amplifier for audio output from the loudspeakers.
