An electroacoustic transducer includes a base plate made of insulating material, a stationary electrode formed on one side of the base plate and made of electrically conductive material, an annular support formed on the same side of the base plate and surrounding the stationary electrode, the annular support being made of the same electrically conductive material as the stationary electrode, and an electrically conductive diaphragm applied on the annular support. |
