Description

[Detailed Description of the Invention] This invention was devised as a method for minimizing sound noise, distortion, etc., and obtaining the best reproduction sound quality when playing records on a stereo player.

Traditionally, when playing records on a stereo player,
Even records recorded by the most outstanding performers, even those made with the highest level of recording technology,
It has been difficult to fully reproduce the sounds produced by musicians.

This utility model was designed to reproduce the sound of a record in the best possible condition by placing the turntable sheet 1 on the turntable and placing the record on top of it. .

Conventionally, a turntable has been made of a metal disk covered with a cushioning material such as velvet, and a record has been placed on top of the turntable.

Originally, the roles of a turntable were (1) to support the record, (2) to give rotation to the record, and (3) to act as a flywheel, giving smooth rotational speed at the same rate. The impact of this was not given much thought.

In addition, since turntables are mainly made of metal, the static electricity generated on the record due to the friction between the record and the stylus has no escape, and along with the generation of static electricity, dust adheres to the record surface, which causes the sound of a stereo recording. If it gets stuck in the groove, it will result in a sound that is completely different from the recorded sound.
Since the needle scrapes up the dirt in the sound groove caused by static electricity, the sound groove becomes increasingly deformed, resulting in a shortened lifespan of the record.

In addition, the cover for records placed on the turntable can be made of a specially processed rubber plate, a ceramic plate with rubber processed on top, a glass plate with pigskin placed on top, or a metal plate such as a copper plate. etc., but we believed that further improvements were needed to reproduce the recorded sound as close to the original sound as possible.

In order to compensate for these shortcomings, I made a turntable sheet 1 with a bamboo mosaic plate as the core material 2 and chamois leather 3 on the front and back sides, placed it on the turntable, and placed the record on it. It was completed by playing.

To explain this idea with a diagram: (1) A smooth mosaic plate with the end of the bamboo as the surface is cut into the size of a turntable, and this is used as the core material 2, as shown in FIG.

(2) Chamois leather 3 is pasted on the smooth front and back surfaces of the core material 2 of the bamboo mosaic plate, and the edges are overlapped and adhesively fixed as shown in FIGS. 2 and 6.

(3) The single bamboo mosaic 4 is made by pasting the bamboo ends together so that the top and bottom sides are on the top and bottom so that the plan view is as shown in FIG.

(4) The core material 2 is made by arranging the bamboo mosaic elements 4 as shown in FIG.

(5) The state of the large and small vertical holes 5 in the bamboo fibers of the bamboo mosaic is as shown in the perspective view of FIG.

Turntable sheet 1 configured as described above
shall be.

When the turntable sheet 1 is placed on the turntable and a record is placed on the turntable and played, the following effects are obtained.

(1) Noise caused by dirt in the sound groove of a record does not enter the reproduced sound.

(2) The high-frequency noise caused by the vibration of the pickup as it slides along the sound groove of the record is absorbed by the large and small vertical holes 5 in the bamboo fibers of the core material 2, and only the recording on the record is electrically reproduced. The recording will be played back with the highest fidelity, allowing you to enjoy the correct sound.

(3) There is no metallic echo of the sound of records.

(4) Static electricity generated on the record surface is absorbed by the chamois leather 3, and new dirt is less likely to stick to the sound groove.

(5) Extends the lifespan of records.
