Description

BACKGROUND OF THE DISCLOSURE

Technical Field

The present disclosure relates to a tonearm of a record player, and more particularly to a static electricity elimination floating tonearm of a record player.

Description of the Related Art

In general, when a record player is in use, a stylus of a tonearm will be placed on the outer circle of a turntable's track, and then as the turntable rotates, the stylus will gradually move along the turntable's track and rubs against the inner circle of the track in order to read music signals and play the music, and when the stylus moves to the inner circle of the track, causing the tonearm to pivot to a termination groove, the stylus will stop moving.

The traditional tonearm is mainly a pivot arm. The pivot arm operates by using an end of the pivot arm as a rotating pivot, which is fixed to one side of the turntable, while the other end of the pivot arm carries a stylus and drives the pivot arm to move in an arc shape across the top of the turntable by turning the pivot of the pivot arm. In terms of physical characteristics, only when the pivot arm is perpendicular to the radius of the turntable can the stylus fall on the position of the tangent point, then the curved arm operated in a curved manner, even with precision adjustment, will only have one or two tangent points, and the rest will have an error, which is known as tracking error. Tracking errors of this sort will lead to the stylus at the front end of the pivot arm unable to travel perfectly in the V-shaped groove, resulting in distortion and error, and lots of overdrives and distortions that often occur in a general turntable are caused by tracking errors.

Therefore, related manufacturers have developed a floating tonearm, such as the “Improved structure of reading arm for record player” disclosed in Taiwan Utility Model Publication No. M288418, wherein a related-art floating tonearm has an air hole formed on a carrier bar, the carrier bar is sheathed with a sleeve, the sleeve is combined with an arm rod, an end of the arm rod is provided with a cartridge, and a stylus is provided inside the cartridge, such that when air blows out from the air hole, the carrier bar at the sleeve is in a frictionless air-floating displacement state, and the stylus can read music information in a more sensitive and responsive manner to reduce the occurrence of audio output distortion.

However, although the aforementioned related-art floating tonearm can make the arm rod to be in an air-floating state, it cannot eliminate the static electricity and dust on the turntable, which will easily lead to the stylus unable to travel perfectly in the sound groove, resulting in popping, sound distortion and other conditions affecting the quality of the sound, and may even damage the stylus or reduce the service life of the stylus, and shock the users by the static electricity on the turntable.

SUMMARY OF THE DISCLOSURE

The present disclosure provides a static electricity elimination floating tonearm, which includes: a tonearm base having an air-floating arm tube horizontally extending from a side of the tonearm, a chamber formed inside the air-floating arm tube, and a plurality of air holes arranged at intervals, formed at the top edge of the air-floating arm tube, and communicated with the chamber; a tonearm, including a floating piece and an arm rod, wherein the floating piece has a cross-section in the shape of a semicircular elongated sheet, and arranged on the air-floating arm tube, the arm rod and the floating piece are combined to form a cross, and an end of the arm rod is provided with a cartridge; and an ion air-pressure device, for generating an airflow with positive and negative ions, wherein the ion air-pressure device includes an air duct communicated with the chamber of the air-floating arm tube, so that the airflow with positive and negative ions is sent into the chamber of the air-floating arm tube, and blown out from the air holes of the air-floating arm tube, so as to drive the floating piece together with the arm rod to be blown upward to define an air-floating state, and blow the airflow with positive and negative ions towards the turntable.

The objective of the present disclosure is not only to make the air-floating arm tube at the tonearm to be in the frictionless air-floating displacement state, but also to allow the stylus to read music information in a more sensitive and responsive manner, so as to reduce the occurrence of audio output distortion and control the airflow with positive and negative ions to blow towards the turntable and achieve the effects of eliminating the static electricity and dust on the turntable, ensuring the perfect sound quality, extending the service life of the stylus, and preventing users from being shocked by the static electricity on the turntable.
