Abstract
The utility model relates to a high-fidelity phonograph oil-holder damping tone arm mechanism, which comprises a record player tone arm and a tone arm support, wherein the tone arm support comprises a suspension arm, a floating body and an oil holder, one end of the suspension arm is fixed on the record player frame, and the other end of the suspension arm is provided with a hang spring, the floating body is overhang on the hang spring, the oil holder is arranged on the lower portion of the floating body, high-viscosity damping oil is placed in the oil cup, the floating body is dipped in the high-viscosity damping oil in the oil holder, and one end of the record player tone arm is fixed on the floating body. The high-fidelity phonograph oil-holder damping tone arm mechanism has the advantages that first, the freedom degree support of the high-fidelity phonograph oil-holder damping tone arm mechanism adopts a floating body damping oil structure, the high-fidelity phonograph oil-holder damping tone arm mechanism overcomes single point type contact of traditional bearings or needle points, therefore minimal sloshing and shaking which are caused by processing precision error does not exist, thereby eliminating noises and distortion which are caused by sloshing and shaking, improving the broadcasting effect of a high-fidelity bakelite audio disk player.
Description
Technical field
The utility model relates to a kind of hi-fi record player parts, particularly a kind of high-fidelity electric phonograph lubricating cup damping tone arm mechanism.
Background technology
In the prior art, being used for tone arm degree of freedom that phonograph recording plays, to support what adopt be bearing or the contact of needle point single-point type, no matter adopt above-mentioned which kind of mode, owing to all can have mismachining tolerance on the equipment machining precision, just can produce thus and small rock and shake, as high-fidelity bakelite disc electric phonograph, this kind rocks and shakes and will reflect by pickup, in playing, phonograph produces noise and distortion, therefore, how to subdue this kind and rock and shake, reduce and eliminate the purpose that the noise that produces therefrom and distortion are the inventor.
Summary of the invention
The purpose of this utility model is to have proposed a kind of high-fidelity electric phonograph lubricating cup damping tone arm mechanism technical scheme, this scheme is provided with the degree of freedom point of a suspended matter as tone arm on the electric phonograph tone arm, what occurred in effectively having solved traditional bearing and the needle point single-point type contacting small rock and shakes, and has suppressed noise and distortion in the bakelite disc playing process.
The technical solution of the utility model is achieved in that a kind of high-fidelity electric phonograph lubricating cup damping tone arm mechanism, comprises that phonograph tone arm and tone arm support; Wherein, tone arm supports and comprises arm, suspended matter and lubricating cup; One end of arm is fixed on the phonograph framework, and the other end of arm is provided with hang spring, and suspended matter is suspended on the hang spring; Lubricating cup is arranged on the suspended matter bottom, is placed with the high viscosity damping oil in the lubricating cup, and suspended matter is immersed in the high viscosity damping oil of lubricating cup, and an end of phonograph tone arm is fixed on the suspended matter.
The utility model has the advantages that:
1. the degree of freedom of tone arm of the present utility model supports the suspended matter damping oil structure that adopts, overcome the contact of traditional bearing or needle point single-point type, thereby do not exist owing to what the machining precision error produced and small rock and shake, and then eliminated the noise and the distortion that produce therefrom, improved the result of broadcast of high-fidelity bakelite disc broadcast phonograph.
2. simple in structure, with low cost, easy to make.
Below in conjunction with drawings and Examples the utility model being done one describes in detail.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment,
Referring to Fig. 1, a kind of high-fidelity electric phonograph lubricating cup damping tone arm mechanism comprises, phonograph tone arm 1 and tone arm support; Wherein, tone arm supports and comprises arm 2, suspended matter 3 and lubricating cup 4; Arm supports 5 by arm and is fixed on the phonograph framework 8, and an end of arm is provided with hang spring 6, and suspended matter is suspended on the hang spring; Lubricating cup is fixed on the phonograph framework and is arranged on the suspended matter bottom, is placed with high viscosity damping oil 7 in the lubricating cup, and suspended matter is immersed in the high viscosity damping oil of lubricating cup, and an end of phonograph tone arm is fixed on the suspended matter, and suspended matter is that the bottom is the suspended matter of circular arc spherical surface; The contact area of suspended matter and damping oil can be adjusted according to playing environment, and then has regulated the ratio of damping of damping oil to suspended matter, to adapt to the influence of different playing environments to tone arm.
What hang spring adopted in the present embodiment is nylon yarn, and suspended matter has been selected golf for use, and the high viscosity damping oil is a silicone oil; The structure of present embodiment has overcome traditional bearing or the contact of needle point single-point type, thereby do not exist owing to what the machining precision error produced and small rock and shake, and then eliminated the noise and the distortion that produce therefrom, improved the result of broadcast of high-fidelity bakelite disc broadcast phonograph.
