Abstract: An ultrathin microchip structure at least includes a flexible base material. The flexible base material includes an installation surface and a printed surface at an upper surface and a lower surface thereof, respectively. The installation surface is provided with one set or multiple sets of integrated circuits. Each of the integrated circuits at least includes a chip and at least one set of transceiver antenna. One or both of the installation surface and the printed surface of the flexible base material is/are applied with a nanometer film layer having characteristics of being waterproof, dustproof, wear resistant, and penetrable by the RF signal, thereby effectively simplifying the present invention as an ultrathin microchip.

Abstract: An outer marginal edge of a loudspeaker cone is connected to an annular suspension member of laminated structure which supports the loudspeaker cone on a support frame. The annular suspension member includes a layer of cloth and a first layer of flexible plastic foam integrally bonded to the cloth. The first layer of foam has an inner surface in contact with the outer marginal edge, and the cloth covers an outer surface of the first layer of foam opposite to the inner surface. A second layer of foam which is thinner than the first layer of foam is disposed between and bonded integrally to the cloth and the first layer of foam. The suspension member is strong and durable and still exhibits good formability and flexibility.
