Adjusting structure of sound arm support

Abstract

The invention discloses an adjusting structure of a sound arm support. The adjusting structure comprises a base, a rotating rod capable of rotating relative to the base is arranged on the base, a sound arm rod perpendicular to the rotating rod is arranged at the upper end of the rotating rod, a stylus used for being in contact with or separated from a record is arranged at one end of the sound armrod, an adjusting block capable of adjusting the dynamic balance of the sound arm rod is arranged at the other end part of the sound arm rod; an adjusting structure is arranged between the base and the rotating rod, and when the stylus is in contact with the disc and moves from the edge of the disc to the center of the disc, the adjusting structure can give opposite force to the rotating rod andenable the sound arm rod to be in balance; when the stylus is in contact with the disc and moves from the edge of the disc to the center of the disc, the stylus generates a force inclining towards thecenter of the disc, namely the sound arm rod inclines towards the center of the disc, and a reverse force is applied to the rotating rod through the adjusting structure, so that the sound arm rod isin a balanced state. Therefore, it can be ensured that the sound arm rod is in a balanced state and the stylus and the disc are in good contact, and good auditory experience is provided for a user.

Description

【Technical field】 [0001] The invention relates to the technical field of phonographs, in particular to an adjustment structure for a tone arm support. 【Background technique】 [0002] The phonograph is an electric device used to play record recordings. It was invented by the American inventor Edison in 1877. The phonograph records can be reproduced in large quantities relatively easily, and the playback time is longer than most cylindrical recording media. Therefore, the phonograph is called It is one of Edison's greatest inventions. The types of phonographs include cassette phonographs, desktop loudspeakers, vertical phonographs, cabinet phonographs, and professional audiophile phonographs. [0003] At present, when the stylus of the tone arm assembly in the phonograph works in contact with the record, the stylus will move from the edge of the record to the center during the rotation of the record, and then the tone arm rod of the tone arm assembly will form a traction force...

Problems solved by technology

[0003] At present, when the stylus of the tone arm assembly in the phonograph works in contact with the record, the stylus will move from the edge of the record to the center during the rotation of the record, and then the tone arm rod of the tone arm assembly will form a traction force from the edge of the record to the center, resulting in The tone arm rod is inclined towards the center of the record, which causes poor contact between the stylus and the record, damages the stylus and the record, and gives users a bad listening experience. At the same time, the stylus is easy to jump from one arc-shaped groove position to another arc-shaped groove position
