Abstract
PURPOSE: To increase the S/N characteristics or sound quality, by providing the player board fitting sound absorption material and antivibration material on the surface opposing to the turn table of the record player and providing the through- hole passing through them.
CONSTITUTION: The turn table 8 of the record player turns with the motor 9. The player board 7 is fixed to the player case 5 via the support member 10. On the surface opposing to the back side of the turn table 8 of the player board 7, the sound absorption member 15 such as foamed styrol, glass fiber or rock wool is fitted, and the through-hole 7a for vent is provided to the player board 7. The sound absorption member absorbs air vibration caused in turning the turn table 8, and improve the S/N or sound quality. Further, by providing the sound proof membe 16 having the similar through-hole 16a between the player board 7 and the sound absorption member 15, the effect of antivibration can further be increased.
