Document Type and Number:

WIPO Patent Application WO/2000/072630

Kind Code:

A1

Abstract:

This invention relates to a multipurpose loudspeaker apparatus with adjustable mode and effect. The loudspeaker apparatus is comprised of a central processor unit (CPU), a working mode indication unit, a reset unit, and a loudspeaker set. It is characterized in that a loudspeaker frequency-division network is provided between the CPU and the loudspeaker set. This frequency-division network can receive commands from the microprocessor unit depending on different input sound sources, in order to make different sound sources output from different loudspeaker sets through different frequency dividers. It is formed a set of sound box which can satisfy different requirements in different musical circumstances, thereby achieving the purpose of effectively reproducing any program signals with only one set of sound box.
