signal spectrum, but also has elegant and beautiful visual effects. The external audio spectrum display described here, and you do not have to make any sound equipment electrical connections, simply placed in front speakers, you can dynamically display a visual spectrum of the audio signal being played, your sound system both nice and good-looking, considerably. The display is designed in all application specific integrated circuits and integrated operational amplifier circuit is simple, stable, easy to manufacture, easy to use, you can also in 100Hz, 300Hz, 1kHz, 3kHz, the 10kHz5 frequency points (with a certain bandwidth), using five dynamic beam shows the instantaneous level of each frequency point. External audio spectrum display function, the speaker is playing sound into light-emitting diode light beam dynamic display.
