[0003] In the existing record town technology, the common mechanical structure is mainly based on the design concept of fixed shape and weight, most record towns are made of single material, and the shape is usually a simple disc, which is directly placed on the vinyl record. From the technical principle, such record town mainly relies on the pressure generated by its own weight to suppress the vibration generated by the record in the high-speed rotation process, and reduces the shaking of the record by increasing the friction between the record and the turntable.
[0004] However, this traditional record town design has significant drawbacks. Since its weight is fixed, it cannot be flexibly adjusted according to the characteristics of different thickness records. Different thickness records produce different vibration amplitudes and frequencies when rotating. The record town with fixed weight cannot form the best damping matching with various records. When facing thin records, the fixed weight is not enough to effectively suppress vibration, resulting in obvious turntable resonance. A large amount of mechanical noise is mixed into the audio signal, seriously affecting the fidelity and stability of the sound quality. This makes the stylus prone to deviation when reading track information, and cannot accurately restore the original sound details of the record, greatly reducing the listening experience of vinyl music. Therefore, a record town is proposed to solve the above problems. UTILITY MODEL CONTENTS
