Abstract

PURPOSE:To analyze the frequency of an input signal and to display the levels of at least >=2 frequency bands on light emitting diodes etc., by providing plural light emitting diodes, resistances, diodes, and a dividing network. CONSTITUTION:An input signal applied to a speaker system is divided into signals by frequency bands through the operation of the dividing network 301 and respective signals are reproduced by speaker units 302, 303, and 304. At this time, the signals are led out of the terminal parts of the respective speaker units and their levels are displayed on the light emitting diodes (LED) 1-15. Namely, the LEDs 1-5 display the signal level of the unit 302, the LEDs 6-10 displays the signal level of the unit 303, and the LEDs 11-15 displays the signal level of the unit 304. Further, the illumination levels of the LEDs are varied by designing the values of the resistances 101-112 and diodes 201-209 properly, and the LEDs are made to ilmunate in order according to the level of the input signal. Consequently, the levels can be displayed by at least >=2 frequency bands.
