Abstract
A speaker diaphragm structure is provided to reduce vibration magnitude at resonance frequency, which includes a hard material diaphragm, a plurality of small area three-dimensional deformation structures formed on the flat area of the hard material diaphragm. The small area three-dimensional deformation structures are used to suppress the vibration of a large area in the diaphragm into a local vibration of a small area, so as to reduce effects of the magnitude and lasting time of the resonance.
