More Information
Summary:The present invention provides a dodecahedral speaker system which reduces loss and heat generation in audio signal simultaneously while making sound pressure characteristics to be flat in a wide frequency band, and especially effectively increases the sound pressure in a low sound area within 50 to 500 Hz. To solve the problem, the dodecahedral speaker system includes a dodecahedral speaker 14 which is formed with twelve speaker units 12, and an equalizer circuit 18 which corrects the specified frequency bands of voice signals outputted from the dodecahedral speaker 14. The equalizer circuit 18 is installed in the front stage of the amplifier 16 to which the dodecahedral speaker 14 is connected.
