An acoustooptic integrated circuit is a special circuit that can produce sound (music or analog sound) and drive light emitting devices.It also falls into the category of music integrated circuits.The acousto-optic integrated circuit can directly drive the piezoelectric buzzer (or loudspeaker) and light-emitting diode (or low pressure small neon lamp) to produce various sound-light effects.It works in sync with sound and light (the light glows with music rhythm) and it works independently.

Scintillating little red star sound-light integrated circuit is divided into 1 sound 1 flash, 1 sound 2 flash, 1 sound 4 flash, 1 sound 7 flash, 1 sound 13 flash and 4 sound 2 flash, 4 sound 5 flash and 8 sound 5 flash.This example takes 1 sound and 7 flash integrated circuit as the core, and the specific circuit is shown in figure 1.D1 ~ D5 select high brightness red led with diameter of 3 mm, which are respectively installed at five angles of small plastic pentagonal star (the other two trigger ends are empty and do not connect), and the connection of buzzer B depends on actual needs

Were reviewed at home and abroad in the future technology development trend of PCB manufacturing is basically consistent, namely to high density, high precision, small aperture, thin wire, small spacing, high reliability, multiple stratification, high-speed transmission, light weight, thin, on the production at the same time to improve productivity, reduce costs, reduce pollution, to adapt to many varieties, small batch production.The technical development level of printed circuit is generally represented by the line width, aperture, thickness/aperture ratio on the printed circuit board.

Pulse signals are output at the end of L1 ~ L5 successively, triggering D1 ~ D5 to flicker in turn.The switch S is made by means of a metal pin on the back of a small five star.When wearing the pin will button up, switch S on, so that the star sparkling, particularly eye-catching.
