摘要： In a diaphragm of an electric sound converter which converts vibration such as sound into an electrical signal, a center dome is reinforced while suppressing variations in the sensitivity and frequency response to the minimum, whereby reduction in a high-pass reproduction limit is suppressed, and occurrence of anomalous resonance is prevented. In a diaphragm 1 of an electric sound converter having a center dome 2, a reinforcing film 7 made of the same material as that of the center dome and formed into the same shape as that of the center dome is applied to the center dome with a hot-melt adhesive 6 of the same nature as that of the center dome, a groove 7a formed in a polygonal reticulate pattern is provided on one surface of the reinforcing film adhered with the adhesive, and a convex rib 8 corresponding to the groove is formed on the other surface.

摘要： The present invention relates to a capacitor microphone unit including a diaphragm, a fixed electrode that is arranged opposite to the diaphragm with a space provided between the diaphragm and the fixed electrode so that a capacitor is formed between the diaphragm and the fixed electrode, an insulating base that is disposed on a rear side of the fixed electrode and supports the fixed electrode, and a ring-shaped acoustic resistance material that is disposed on a front side of the insulating base, all of which are incorporated in a unit casing. A skin layer is formed on at least one of a front side and a rear side of the acoustic resistance material, and the skin layer has a higher density than that inside the acoustic resistance material, whereby acoustic resistance can be readily controlled.
