JPS609989Y2 - Suspension system in record player - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a suspension system for a record player.

Generally, in a record player, the chassis on which the turntable and tone arm are mounted is suspended on an elastic member such as a spring so that vibrations from the floor etc. are not directly transmitted to the turntable and tone arm mounted on the chassis. A suspension system is used.

The present invention provides a suspension system for a record player that is highly effective as the suspension system described above.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a player cabinet made of synthetic resin or the like, and a sleeve 4 and rubber feet (elastic feet) 5 are attached to a support 2 of the cabinet with screws 3.

A male thread is carved around the periphery of the sleeve 4, and a spring receiver 6 is screwed into the male thread.

A spring 8 to which a damper rubber 7 is fitted is disposed on the spring receiver 6, and a chassis 9 is placed on top of the spring.

A well-known motor 10, a turntable 11, a tone arm (not shown), and the like are mounted on the chassis 9.

Reference numeral 12 indicates felt attached to the rubber feet 5.

In the suspension system for a record player configured as described above, vibrations from the floor are first absorbed by the first insulator made of felt 12 and rubber feet 5, and the remaining vibrations are absorbed by the first insulator made of damper rubber 7 and spring 8. It is absorbed by the second insulator.

By making the so-called Q or resonance frequencies of the rubber feet 5, spring 8, and damper rubber 7 different from each other,
It is possible to further prevent vibrations from the floor from being transmitted to the chassis 9.

Note that by rotating the spring receiver 6, its axial position can be changed, so the height of the chassis 9 can be changed.

As described above, the present invention includes a rubber foot 5, a sleeve 4 provided with threads around the periphery, and a screw 3 for attaching the rubber foot 5 and sleeve 4 to the support 2 of the player cabinet 1.
The spring receiver 6 is screwed onto the thread of the sleeve 4, and the spring 8 is fitted with a damper rubber 7. Since the chassis 9 is placed on top, when the height of the chassis 9 is adjusted by rotating the spring receiver 6, no rotational load is directly applied to the screws 3, and the screws 3 do not loosen.
