LOUDSPEAKER EQUIPPED WITH MEASUREMENT OF THE MOVEMENT OF THE LOUDSPEAKER UNIT AND A METHOD FOR MEASURING THE MOVEMENT OF THE LOUDSPEAKER UNIT IN A LOUDSPEAKER

摘要

The present invention relates to a kind of loudspeakers equipped with the measurement loudspeaker unit moved. Loudspeaker in-cludes loudspeaker units (1-8) and a compo-nent (4) are set as the clause of vibration in addi-tion, it include conduction surfaces (9,11) in the presence of at least one capacitor in loudspeaker, for measuring the movement (4) in the component, by means of the variation of capacitor. The capacitor of the normals conduction surfaces (9,11) is substantially at the variation that capac-itance occurs in vibration component (4) region of right angle direc-tion movements, to measure the movement. The present invention also relates to a kind of loudspeakers of motion measurement loudspeaker unit.
