Abstract
A casing of a sound record playing apparatus includes an upper body (1B) and a lower body (1A), and a vibration plate (16) is formed by reducing a thickness of a part of the upper body. An inner surface of the vibration plate is in abutment with a pickup (13) to amplify the vibrations of the pickup. Thus, a conical speaker which has been used conventionary can be eliminated, and the thickness of the recording disk reproducing apparatus is reduced.
Claims2
A sound record playing apparatus for playing a disk record and having a reduced height, comprising:
- a casing defined by a parallel upper part (1B) and lower part (1A), wherein the lower part has a continuous first thickness and the upper part includes a first portion adjacent a disk pickup (13) and a second portion having said first thickness distant from said pickup;
- and wherein said first portion defines a vibration plate which abuts a top portion of said pickup when said disk record is being played, and has a second thickness substantially less than said first thickness;
- said disk record having an upper surface, the disk record having a modulated groove formed on the upper surface of the disk record, the disk record deployed in a cavity of the casing;
- said disk pickup for scanning the modulated groove of the disk record, the pickup being deployed within the cavity of the casing;
- and
- wherein the pickup is mounted on a tone arm coupled to said casing.
