Abstract
PURPOSE: To make it possible to reproduce original sound faithfully by forming the cabinet, the turntable, the speaker box and the speaker frame for record player with Al+Si alloy containing a specific quantity of silicon which has a structure capable of crystallizing a proeutectic silicon.
CONSTITUTION: The cabinet, the turntable, the speaker box and the speaker frame for record player are formed with the Al+Si alloy containing silicon of 10W50% and moreover has structure of crystallizing a proeutectic silicon. As a result, uniform acoustic pressure is obtained throughout all frequency bands, so that original sound can be reproduced faithfully.
