Abstract

PURPOSE:To increase the ratio of young's modulus E and density rho of the oscillating bodies for speakers, microphones, etc., or the oscillating bodies for the electroacoustic trunsducers such as the cantilevers of pick up cartridges, to supply them with suitable internal losses and to improve the characteristics of oscillating bodies.
