Abstract

The invention discloses a magnetic positioning air flotation turntable which comprises a rotary table (1) and a support plate (2).A rotary table magnet (3) is inlaid in the middle of the bottom face of the rotary table (1); the support plate (2) is located below the rotary table (1), a support plate magnet (4) is inlaid in the middle of the top face of the support plate (2), the rotary table magnet (3) and the support plate magnet (4) are mutually attracted, an annular buffer slot (6) is formed in the top face of the support plate (2), and an admission piece (5) is connected to the annular buffer slot (6).According to the air rotary table system, the revolution precision is high, vibration is small, no direct contact exists, and no friction loss exists.The magnetic positioning air flotation turntable can be applicable to the production demands of high-end long-playing players.

Description

technical field [0001] The invention belongs to the field of vinyl record player manufacturing, and relates to a magnetically positioned air-floating disc. Background technique [0002] The turntable is an important part of the vinyl record player, and the stable rotation of the turntable is very important for the sound quality of the turntable. Vinyl record players rely on the vibration of the stylus to play music signals, and the vibration and friction generated when the turntable rotates will cause the sound quality of the record player to deteriorate. At present, many turntables use oil pressure, springs or air suspension to suspend the turntable to achieve the purpose of shock absorption. However, the current floating turntable design has many shortcomings, such as difficult processing and poor shock absorption effect, so there is an urgent need for a floating turntable system that can be applied to high-end vinyl record players. Contents of the invention [0003] I...
