Abstract
- acoustic transducer, of the variable resistance type, in which the absolute resistivity of a mass of grains of a material of low resistance depends on its compactness, determining the value of the electrical resistance between two metal parts separated by said mass, characterized essentially because one of the main metal parts, physically attached to the housing of the device and located axially relative to it, has its head, in permanent contact with the mass of grains, in the form of a bowl with a central conical elevation, determining a meridian section in the form of an open and elongated omega, while the second metal component, also in permanent contact with the grain mass and axially solidary of the vibrating membrane, has a cup configuration, with its bottom in a conjugated form with that of the first element being retained the mass of grains, with freedom, total for its movement, by means of a thin sheet and fle it is held by its edges by an annular piece of L-shaped section that surrounds the cylindrical and insulating support that contains the mass of grains, which is contained inside a circular cavity formed by a truncated cone and surrounded by the annular piece of section in l.
