MICRO-SPEAKER

摘要

A micro-speaker includes a speaker monomer, a housing and a waterproof membrane. The housing accommodates the speaker monomer and has an opening to output a sound generated by the speaker monomer. The waterproof membrane seals the opening and transmits the sound generated by the speaker monomer. The waterproof membrane has a center area and a peripheral area surrounding the center area, and a stiffness of the center area is greater than a stiffness of the peripheral area.
