Abstract: A holder is for a small-sized acoustic element and a mounting structure for the same allowing mounting to a casing with a sound hole in a side surface thereof without involving a substantial increase in the thickness of a portable communication apparatus. The holder for a microphone has a cylindrical portion for holding the outer peripheral surface of a small-sized acoustic element. The cylindrical portion is equipped with an inwardly directed flange adapted to be engaged with a holed surface of the small-sized acoustic element and constructed of an annular rubber-like elastic member. Further, the cylindrical portion is provided with a groove-shaped sound hole whose one end is open in the inner peripheral surface of the inwardly directed flange and whose other end is open in the outer peripheral surface of the cylindrical portion, thus communicating with both the holed surface of the small-sized acoustic element and the sound hole formed in a side surface of the casing of the portable communication apparatus.

Abstract: An apparatus for manufacturing an anisotropic formed body in which functional, magnetic fine particles are oriented in a specific direction within a matrix and in which anisotropy is given to properties attributable to the functional fine particles. The apparatus allows use of a wide variety of materials as the functional fine particles and realizes an anisotropy which is parallel and of a uniform interval within a large area. Further, a method for manufacturing an anisotropic formed body, includes applying, by using a superconducting magnet device, a uniform and parallel magnetic field with magnetic lines of force at equal intervals and parallel to each other, to a mold in which the matrix is filled with a liquid molding material containing functional, magnetic fine particles, to orient the functional fine particles in a direction of the magnetic lines of force, whereby the liquid molding material subsequently hardens.

Abstract: A method is provided for manufacturing a holder which has a holding part and a connector part. The holding part has an elastic body holding a built-in electronic part in a position. The method steps include pouring a liquid polymer mixed with a magnetic electric conductor into a mold for forming the holder. A magnetic force is applied to a desired position in the mold to orient the magnetic electric conductor to form a connector pattern of the connector part with the magnetic force. A holding part is molded integrally with the connector part to provide a one piece integral structure by crosslinking the liquid polymer. The magnetic electric conductor may be linked together by a force of a magnetic field. This defines a conductive passage in the connector part.

Abstract: A holder 1 forming monolithically a holder portion for holding a small size sound device 2 and an elastic conductive connector 11 for electrically connecting said small size sound device 2, wherein an acoustically required communication sound hole 13 is provided on a point corresponding to the sound hole 22 on the back face of the small size sound device 2 and, moreover, a test electrode section 14 used for leak test is provided, separately from the elastic conductive connector 11, without obstructing the acoustically required sound hole 13 on the back face of the small size sound device 2, and allowing also to simplify the mounting process, reduce the production cost, reduce the mounting position space of the small size sound device 2, and facilitate the leak test of the small size sound device 2.

Abstract: A holder with electrodes of a built-in electronic part such as a small type microphone or a loud speaker, etc. and electrodes of a substrate are connected with each other. The holder uses an elastic connector part, and a holding part to hold the built-in electronic part, which is integrally molded with the elastic connector, and thereby a soldering process for connecting lead wires, etc. is eliminated. Holder parts of complex shape can be integrally molded with the elastic connector part.
