Abstract

PURPOSE:To obtain a speaker box without box howling by providing a permeability in a constituting metal plate and holding a viscoelastic high polymer material high in an oscillating and damping capacity in a sandwich form. CONSTITUTION:The speaker box 1 formed in the box shape in which speaker units 2, 3 are incorporated is formed by working the metal plate 4 holding the viscoelastic high polymer material 4b between steel plates 4a in the sandwich form according to a press molding method. Since an internal loss is provided in the damping plate of the metal plate 4, the speaker box 1 according to the press molding can be attained. An oscillation generated at the time of driving the speaker units 2, 3 is absorbed as a viscoelastic hysteresis due to an extension deformation and a dislocation deformation by the viscoelastic high polymer material 4b to damp. Thereby, the characteristic resonance of the speaker box 1 can be remarkably lowered.
