Title: Tomoyuki Shimada: Innovator in Speaker Technology
Introduction
Tomoyuki Shimada is a notable inventor based in Kanagawa-ken, Japan. He has made significant contributions to the field of speaker technology, holding a total of 3 patents. His innovative work focuses on enhancing the performance and durability of speaker components.
Latest Patents
Shimada's latest patents include a "Speaker voice coil bobbin and method of manufacturing same." This invention involves a voice coil bobbin formed from a material that combines a fiber-type material and a ceramic-type coating agent, which includes metal alkoxide, metal hydroxide, and a colloidal or fine-particulate inorganic substance. The combining process for the ceramic-type coating agent is performed before or after the fiber-type material is shaped into the voice coil bobbin. Another significant patent is for "Ceramic insulation coated electric wire self-fusing ceramic insulation coated electric wire coating composition and coil and voice coil for speaker." This patent describes a coating composition containing a zirconium compound and a silicon compound that is applied to a conductor and baked to develop a ceramic insulating coating. A bonding agent made by dissolving a polyamide resin or a polyimide resin into an organic agent is then applied on the ceramic insulating coating and baked to create a fusible coating. This innovation produces a self-fusible ceramic insulation coated wire that retains favorable properties at high temperatures and can be used for windings such as high-power loudspeaker voice coils.
