Diaphragm for attenuating harmonic response in an electroacoustic transducer |
摘要 |
A circular diaphragm typically edge mounted to the housing of an electroacoustic transducer includes a plurality of inwardly curved slots isolated by a circular ridge formed in the diaphragm to thereby increase the compliance of the diaphragm at the center of the circular ridge. Portions of the slots are overlapped to maintain a substantially rectangular section of the diaphragm between the slots. The slotting and rectangular sections of the diaphragm allow the center of the circular ridge to flex in a piston-like manner whereby higher frequency flexural modes of the diaphragm are either reduced or completely eliminated.
