Abstract

PURPOSE:To improve acoustic characteristics by employing the constitution of a ceramic formation body using as a binder resin or rubber which is more than 20% in air permeability and less than 300 micron in bubble diameter. CONSTITUTION:This is made of a ceramic formation body which is not less than 20% in air permeability and not greater than 300 micron in bubble diameter on average, a body obtained by impregnating at least part of bubbles of this formation body with an elastic substance such as rubber and resin, a formation body obtained by combining ceramic powder by resin or rubber, and a body obtained by impregnating at least part of bubbles of this formation body with an elastic substance such as rubber and resin. This ceramic material is given adequate rigidity to absorb strong vibrations caused by sound pressure and mechanical vibrations generated from a speaker, and air permeability is increased above 20% to attenuate the internal loss of the speaker as quickly as possible.
