PURPOSE:To ensure the natural function type vibration attenuation waveform by forming both the speaker box and the buffle plate with the ceramics containing pores. CONSTITUTION:The pores among the ceramics crystal particles are scattered over a uniform and wide range, and the diameters of the pores are averaged to 300mu or less. In such way, the ceramics sintered substance is formed. Then the speaker box and the buffle plate are made of such ceramics sintered substance, and as a result the sound pressure and the mechanical vibration caused by the speaker can be attenuated quickly by the pores of the ceramics sintered substance. |
