ABSTRACT:
A visual display is disclosed which includes a flexible elongated electroluminescent light source, whose emitted light varies in accordance with an electrical signal applied thereto, and is connected to the output of an audio output amplifier. The particular characteristics of the light emitted by the electroluminescent light source, such as color and brightness, will vary in accordance with the frequency and output of the audio signal applied thereto. Hence, the electroluminescent light source will provide a visual display which is instantaneously representative of the output signal of the audio amplifier. The electroluminescent light source may be used to provide a low interference connection between the audio output signal and earphones, such as typically used in a personal audio player.
