Audio spectrum columnar display

Abstract

The invention discloses an audio spectrum columnar display. The audio spectrum columnar display comprises an equalizer, an audio power amplification circuit, a filter, a columnar display circuit and a power source. The input of the equalizer is connected with an audio input while the output thereof is connected with an input of the audio power amplification circuit; the output of the audio power amplification circuit is connected with the input of the filter; the output of the filter is connected with the columnar display circuit; the power source respectively supplies power to the equalizer, the audio power amplification circuit, the filter and the columnar display circuit; the columnar display circuit comprises a light column and a driving circuit thereof; and the light column is composed of multiple light emitting diodes. The audio spectrum columnar display is simple in structure, can display the spectrum of audio signals intuitively and dynamically and can be detachably connected with a sound device. The audio spectrum columnar display regards an integrated block as a core, has a small number of peripheral components and parts, and is simple in circuit, steady in work, easy to produce and convenient to use.
