CFRP shell
The most requested thing in the head shell. It highly rigid yet lightweight, with a high toughness, thereby quickly attenuate the vibrations. In Oyaide electricity as those conditions are met the best of the material, we chose the CFRP.
Shell portion of 4mm thickness is formed from the prepreg material made of 17 layers (carbon fiber board). And, so as to obtain maximum vibration damping characteristics than the design stage, with the exception of the one layer of the center, were all aligned in a single direction. In addition, the matrix using a high-toughness epoxy resin, strength properties does not have to be changed permanently. In addition, also show a commitment to shape. By adhesive bonding, hate the disturbance of the vibration moment, the shell portion is integrally molded angle has been made by the mold. Then, one by one cutting process is performed by the CNC Mashininingu, it will be completed as a part.
Also CFRP material forming the head shell, and show a commitment of Oyaide electricity to seek a high-quality. The core, prepreg material has also been used to Boeing of the new machine, manufactured by Toray Industries, a high-strength adopt a carbon fiber "T700". And, on the surface material, adopting the "1K cross" of Toray Industries, made of carbon fiber "T300". This carbon cloth, and give a strong impression of the charm of the HS-CF oozes spartan atmosphere in the grace.
Shell lead wire (HSR-AG)
Because it is simple it must be built precisely. This is also the philosophy of Oyaide electricity, is also the craftsmanship.ELEC electrical likeness to shell lead wire has been put.
Continuous casting by under a high-frequency electric furnace of advanced production management, cold as many as 19 process rolling, annealing work over twice, drawing process by the diamond die, performs such as skin-pass processing, not only high silver purity of, use a high-quality no gap "high purity silver wire" in the crystal grain boundaries. 5N sterling silver single line of them advanced production management 0.2mm which has been under production of, twisted in seven secure a sufficient cross-sectional area (0.2sq). It suppresses the conductor resistance to the maximum.
Adopt the insulation of the double by silk is an insulator. Adoption of natural materials does not charge the static electricity generated in the analog playback is the purpose is possible to achieve a clean signal transmission.
Resin-based material (PVC, fluorine resin, etc ..) is by the action of the negative charge, is easily charged material the static electricity. In contrast, silk in the static electricity is hardly charged material, yet has excellent electrical characteristics.Similarly, glass fiber sleeve employed in the exterior, it is charging hardly material of high insulation property and static electricity.
And it alive shell chips Oyaide electrical likeness which is attached to the terminal. The base material adopts the high spring of phosphor bronze, enhances the adhesion rate of the contact pin. In addition to the surface employs a rhodium-plated to prevent oxidation.
