Description

Technical Field

[0001] This utility model relates to the field of record player technology, and in particular to a vinyl record player with noise reduction function. Background Technology

[0002] The phonograph is an electric device used to play recorded music; it was invented by American inventor Thomas Edison in 1877. Phonograph records could be easily mass-produced, and the playback time was longer than most tube recording media. Therefore, the phonograph is considered one of Edison's greatest inventions. Types of phonographs include cassette phonographs, tabletop phonographs, floor-standing phonographs, cabinet phonographs, and professional audiophile phonographs.

[0003] Currently, the working process of a record player can be summarized as follows: the stylus reads the vibration of the grooves on the record, converts it into a weak electrical signal, amplifies and processes it, and finally converts it into sound by the speaker.

[0004] However, current record player playback devices, especially vinyl record players, may be affected by external environmental noise during playback, which affects the sound quality. Existing noise-canceling record players still have limited noise reduction effects. In particular, when playing music on a table with different materials and heights, the machine's balance and stability are affected by the different levels of the table, resulting in unstable playback and difficulty in guaranteeing music quality. When adjusting the tilt angle of the record player, users often rely on experience or visual judgment, which is not precise enough and increases the difficulty of setting up the device.

The handle 10... One end of the tonearm 11 is fixedly connected to the rotating shaft seat 9, and the other end of the tonearm 11 is fixedly connected to the cartridge 16. The stylus is located at the bottom end of the cartridge 16. The support base 12 is fixedly installed on the top of the adjustment base 6, and the support groove 15 is located on the top of the support base 12. The tonearm 11 is movably located on the top of the support groove 15, and one end of the pawl 14 is rotatably connected to one side of the support groove 15 by a torsion spring. When the tonearm 11 is not in use, the pawl 14 is engaged with the tonearm 11.

[0038] Specifically, the record player assembly's reading system achieves efficient and stable music playback through precise design. The adjustment base 6 is fixed to the top of the record player to support the assembly and horizontal adjustment of the entire reading assembly. The horizontal adjustment knob 7 is used for fine-tuning the horizontal position of the entire assembly; it can be adjusted via gear transmission or other means. The mounting bracket 8 is fixedly mounted on the adjustment base 6, ensuring the stable installation of the rotating shaft seat 9. The rotating shaft seat 9 can rotate vertically, allowing the stylus to be placed. Both ends of the rotating shaft seat 9 are movably inserted into the mounting bracket 8, allowing it to rotate freely within the mounting bracket 8. The fixed connection between the handle 10 and the rotating shaft seat 9 provides manual rotation. For convenience, one end of the tonearm 11 is fixedly connected to the rotating shaft seat 9, and the other end is fixedly connected to the cartridge 16. The entire system can gently move the stylus to different positions on the record surface as the tonearm 11 swings. The stylus is located at the bottom of the cartridge 16 and can accurately read the audio information on the record. The support base 12 is fixed on the adjustment base 6. The opening of the support groove 15 ensures that the tonearm 11 can be firmly locked when not in use, preventing damage to the record or equipment due to external disturbances. The pawl 14 is connected to one side of the support groove 15 through a torsion spring, so that the tonearm 11 can be safely locked in the support groove 15 when not in use, to protect the components from damage.

[0040] Specifically, the use of a protective cover 3 and a protective grille 2 can protect the speaker assembly 23 without affecting the sound quality of the broadcast.

[0041] In summary, compared with existing technologies, this record player has at least the following advantages: By incorporating an adjustment mechanism, when in use, the record player casing 1 is placed on a table, and the dual-axis digital display inclinometer 31 is turned on to measure the horizontal angle of the casing 1. If the inclinometer 31 indicates that the record player is not level, the data is fed back to the controller. The controller then issues an instruction to adjust the electric push rod 28, thereby adjusting the positions of the support legs 30 and foot pads 29, thus adjusting the levelness of the casing 1 and keeping the record player level. This improves the balance and stability of the record player, resulting in more stable playback and guaranteed music quality. The self-adjustment is convenient and precise, reducing the adjustment burden. The attitude and levelness of the record player are adjusted according to the inclinometer indication on the inner wall of the bottom of the casing 1, ensuring optimal sound quality during playback. Through the coordinated work of these components, the record player can not only adapt to the height requirements of different environments, but also ensure horizontal stability and clear sound quality during playback, thereby improving the overall music experience and reducing noise interference. The infrared rangefinder sensor component 26 can monitor the adjustment stroke and then feed the data back to the controller. When the appropriate height is reached, the operation of the electric push rod 28 is stopped immediately. The entire system can be programmed using PLC.
