Description

TECHNICAL FIELD

[0001] The utility model relates to a record player technical field, especially a portable record player. BACKGROUND

[0002] A record player is a device that plays records by outputting audio signals through electricity. It can convert the sound on the record into an electrical signal and then output it to the human ear through a loudspeaker and a sound box to achieve music playback. The record player first appeared in the 1920s. Its working principle is to convert the sound on the record into an analog electrical signal through a stylus and a sensor, then amplify it through an amplifier, and finally convert it into sound output through a sound box. Modern record players usually include a motor, a turntable, an arm, and a stylus.
