Abstract

PURPOSE:To prevent the resonance between the diaphragm and the fixing component and then to prevent the lower harmonic distortion by forming the protrusion part on the upper surface of the magnet, thus improving the sound quality. CONSTITUTION:A number of protruded streaks 2 the both side faces of which protrude in the arc shapes are formed in parallel to one another, and the thin-film material in which conductors 5 and 6 are mounted at each valley part 4 is added to form diaphragm 8. Then magnet 23 is mounted to magnet support lever 22 as if it were held between parts 4 in order to generate the magnetic flux which is orthogonal to condutors 5 and 6 at part 4, and lever 22 and magnet 23 are fixed via fixing tool 24. As a result, the resonance can be prevented between diaphragm 8 and fixing component 24, and thus the lower harmonic distortion can be avoided. In this way, the sound quality can be improved.
