Description
この考案は、ＵＳＢ端子に装着してパソコン及びＵＳＢ端子から発生する電磁場をシールドするアタッチメントに関するものである。
パソコンからＵＳＢケーブルを経由してデジタルアナログコンバータ（ＤＡＣ）に音楽信号を送る際に、パソコン及びＵＳＢ端子から発生する電磁場に起因したノイズが音楽信号に乗り、音質の劣化を招いている。従来このようなノイズを除去する様々な取り組みがなされてきたが、ＵＳＢ端子に直に電磁場シールドアタッチメントを装着してノイズを除去するという試みはなかった。The present invention relates to an attachment that is attached to a USB terminal and shields an electromagnetic field generated from the personal computer and the USB terminal.
When a music signal is sent from a personal computer to a digital-analog converter (DAC) via a USB cable, noise caused by an electromagnetic field generated from the personal computer and the USB terminal rides on the music signal, causing deterioration in sound quality. Conventionally, various efforts have been made to remove such noise, but there has been no attempt to remove noise by attaching an electromagnetic field shield attachment directly to the USB terminal.
従来、パソコン及びＵＳＢ端子から発生する電磁場に起因したノイズを除去する様々な取り組みがなされてきたが、主にＵＳＢ端子やコードの改善に向けられており、ＵＳＢ端子に直に電磁場シールドアタッチメントを装着してノイズを除去するものはなかった。
サエクコマース株式会社はＵＳＢ端子に特殊ゲル製のパッドを装着しパソコン等の振動を抑制する端子振動防止パッドを発売した。これは、パソコン等の振動を抑制し音質劣化を抑制するもので、ＵＳＢＡ端子用のパッドのサイズは１６ｍｍ×８．５ｍｍ×２ｍｍ、ＵＳＢＢ端子用のパッドのサイズは１２ｍｍ×１１ｍｍ×２ｍｍである。だがこれらのパッドは振動の抑制を目的にしており、本考案とは機能、構造そして効果が異なる。Conventionally, various efforts have been made to remove noise caused by electromagnetic fields generated from personal computers and USB terminals, but the main focus has been on improving the USB terminals and cords, and electromagnetic field shield attachments are directly attached to the USB terminals. And there was nothing to remove the noise.
Saek Commerce Co., Ltd. has released a terminal vibration prevention pad that attaches a special gel pad to the USB terminal and suppresses vibrations of personal computers. This suppresses vibration of a personal computer or the like and suppresses deterioration of sound quality. The size of the pad for the USBA terminal is 16 mm × 8.5 mm × 2 mm, and the size of the pad for the USBB terminal is 12 mm × 11 mm × 2 mm. However, these pads are designed to suppress vibrations and differ in function, structure and effect from the present invention.
パソコン及びＵＳＢ端子から発生する電磁場はデリケートな音楽信号にノイズとして乗り、音質を劣化させる。電磁場をシールドするさまざまな方策が採られてきたが、電磁場の発生源に近いＵＳＢ端子に直に装着し電磁場をシールドするという方法はこれまでなかった。本考案は高音質を求める使用者の要望に応えるために考案されたものである。The electromagnetic field generated from the personal computer and the USB terminal rides on a delicate music signal as noise and degrades the sound quality. Various measures have been taken to shield the electromagnetic field, but there has never been a method for directly shielding the electromagnetic field by attaching it to a USB terminal close to the source of the electromagnetic field. The present invention has been devised to meet the demands of users who demand high sound quality.
いま、その構成を説明すると、
（ア）本考案は、ＵＳＢ端子に着装する開口部のある銅合金メッシュ（１）とシルク（２）とを幾重かに重ねたアタッチメントである。なお本アタッチメントはＵＳＢオス端子に装着する。
（イ）本アタッチメントの開口部にＵＳＢオス端子を入れ、ＵＳＢオス端子の奥まで本アタッチメントを差し込む。
以上のように装置する。
使用法は、ＵＳＢオス端子に本アタッチメントを装着した後、パソコン等のＵＳＢメス端子に差し込む。このようにＵＳＢメス端子に電磁場をシールドする本アタッチメントを装着することで、電磁場の発生源の直近で電磁場をシールドでき効果的にノイズを除くことができる。なお、ＵＳＢ端子には形状の異なるＴｙｐｅＡ、ＴｙｐｅＢ、Ｍｉｎｉ−Ａ、Ｍｉｎｉ−Ｂ、Ｍｉｃｒｏ−Ａ、Ｍｉｃｒｏ−Ｂがあり、いずれの端子の場合でも形状に応じた開口部、そして厚さにする必要があり、かついずれもオス端子に装着する。
また、ＡＶ端子の場合でもＵＳＢ端子と同様それぞれのＡＶ端子の形状に応じた開口部、そして厚さにする必要がある。ＡＶ端子の代表的な端子であるＲＣＡ端子の場合、ＲＣＡオス端子とＲＣＡメス端子との形状を見ると、本アタッチメントはＲＣＡメス端子に装着する必要がある。ピン端子、ヘッドホーン端子そして音声と映像に用いられているＨＤＭＩ端子の場合、本アタッチメントはオス端子に装着する。なおＡＶ端子の形状によってはアタッチメントの厚さをごく薄くする必要がある。
また、銅合金メッシュ（１）の代わりに多くの小さな穴を開けた銅合金板にしても、同様の電磁場シールド効果が得られる。
かつまた、銅合金メッシュ（１）とシルク（２）とを固着する際に、弾力のあるシルク等で包み込んでやれば、パソコン等からの振動を抑制することができる。Now, to explain its configuration,
(A) The present invention is an attachment in which a copper alloy mesh (1) having an opening to be attached to a USB terminal and silk (2) are stacked several times. This attachment is attached to the USB male terminal.
(A) Insert the USB male terminal into the opening of the attachment, and insert the attachment to the back of the USB male terminal.
The apparatus is as described above.
To use, attach this attachment to a USB male terminal and then plug it into a USB female terminal such as a personal computer. By attaching the attachment for shielding the electromagnetic field to the USB female terminal in this way, the electromagnetic field can be shielded in the immediate vicinity of the electromagnetic field generation source, and noise can be effectively removed. In addition, there are Type A, Type B, Mini-A, Mini-B, Micro-A, and Micro-B with different shapes in the USB terminal, and it is necessary to make the opening and thickness according to the shape in any terminal. And both are attached to male terminals.
In the case of an AV terminal as well, it is necessary to make an opening and a thickness corresponding to the shape of each AV terminal as with the USB terminal. In the case of an RCA terminal which is a typical terminal of the AV terminal, it is necessary to attach this attachment to the RCA female terminal when looking at the shapes of the RCA male terminal and the RCA female terminal. In the case of a pin terminal, a headphone terminal, and an HDMI terminal used for audio and video, this attachment is attached to a male terminal. Depending on the shape of the AV terminal, it is necessary to make the thickness of the attachment very thin.
The same electromagnetic field shielding effect can be obtained by using a copper alloy plate having many small holes instead of the copper alloy mesh (1).
Moreover, when the copper alloy mesh (1) and the silk (2) are fixed, if they are wrapped with elastic silk or the like, vibration from a personal computer or the like can be suppressed.
本アタッチメントは、電磁場シールド材としてよく知られている銅合金メッシュとシルクから構成されており、ＵＳＢ端子に直に装着するため、電磁場をシールドする効率は高い。それ故音響機器だけでなくデリケートな信号を扱う医療機器にも利用できる。他にもデリケートな信号を扱うさまざまな情報機器にも利用できる。 This attachment is composed of a copper alloy mesh and silk, which are well known as electromagnetic field shielding materials, and is attached directly to the USB terminal, so that the efficiency of shielding the electromagnetic field is high. Therefore, it can be used not only for audio equipment but also for medical equipment that handles sensitive signals. It can also be used for various information devices that handle sensitive signals.
