Abstract A circular and uniformly vibratable type diaphragm for electroacoustic transducer of flat-plane driving types is provided. The diaphragm comprises a circular nonmagnetic and insulative membrane and a series of conductors formed on the membrane and comprises radial outlet parts extending as mutually spaced at regular intervals substantially from central field to peripheral field of the membrane, arcuate outlet parts extending in the peripheral field and connecting most of peripheral side ends of the radial parts, and central parallel parts to be subjected to magnetic fluxes of associated magnetic circuits as concentratively arranged in the central field and connected in series with the other central side ends of the radial parts. Remaining two peripheral side ends of the radial parts not connected are adapted to be input or output ends of the series conductors. The shape of the central parts of the conductors is advantageously similar U-shapes.
A diaphragm for electroacoustic transDucers comprising a circular diaphragm membrane of a nonmagnetic and highly insulative material, and a series of conductors formed on said membrane and including radial outlet parts arranged substantially at regular intervals as extended from central section to peripheral section of the circular membrane, arcuate outlet parts respectively connecting said radial outlet parts with one another at their ends on the peripheral side, and central parallel conductor parts disposed substantially in the central section of the circular membrane and connected in series with the other central side ends of the radial outlet parts.
