Color organ |
摘要 |
A sound responsive color organ includes a transducer to convert sound to electricity, an amplifier to increase the level of electricity, and an automatic gain control that operates under the influence of a time dependent circuit to control the output level of the amplifier. The time dependent circuit operates at one rate when increasing the amplifier gain and at a second rate when decreasing the amplifier gain. A network is included to adjust the frequency response of the amplifier to predetermined limits. The amplifier output is used to control switching devices that turn on and/or off lights in a display located behind color masks. Located in front of the color masks is a lenticular surface which further affects the light sources to yield geometric patterns comprising the effect of the masks and the lens types.
