摘要： A piezoelectric electroacoustic transducer includes a piezoelectric sounding body in which bending vibration is generated by applying an alternating signal between two electrodes, a case housing the piezoelectric sounding body, and a pair of terminals insert-molded in the case. In the piezoelectric electroacoustic transducer, internal connection portions of the pair of terminals are exposed on the inside surface of the side wall portion of the case so as to extend in a direction that is substantially perpendicular relative to the piezoelectric sounding body, and the internal connection portions of the terminals are electrically connected to the electrodes of the piezoelectric sounding body by using conductive adhesive. The internal connection portions of the terminals do not largely extend inside the case and accordingly, the dimensional difference between the case and the piezoelectric sounding body is minimized.

摘要： A piezoelectric electroacoustic transducer eliminates the need for the interconnection between main surface electrodes and internal electrodes, and is capable of constructing a bimorph diaphragm using a simple connection structure. The piezoelectric electroacoustic transducer includes a laminated body formed by laminating two or three piezoelectric ceramic layers, main surface electrodes each provided on the top and bottom main surfaces, and an internal electrode provided between any adjacent two piezoelectric ceramic layers. In the piezoelectric electroacoustic transducer, all ceramic layers are polarized in the same direction with respect to the thickness direction, and by applying an alternating voltage across the main surface electrodes and the internal electrode, the laminated body generates a bending vibration in its entirety.

摘要： A communication cable having a communication wire and an armor including at least two synthetic resin layers, and protects the communication wire in a loose state. The communication wire protecting tube includes at least two synthetic resin layers, and inserts the communication wire in a loose state. The most hard resin layer of the armor has a crosswise or spiral annular groove or cut portion continuous in the longitudinal direction to reach the radially inner face, and the outermost layer of the armor is formed of a protective layer made of a softer resin than the hard resin layer. The adjoining edge portions of the annular groove or the cut portion come, when the communication wire is to be bent, into contact with each other so that it may be prevented from being bent to a predetermined or smaller bend radius.

摘要： A piezoelectric electroacoustic transducer includes a substantially rectangular piezoelectric diaphragm having electrodes and flexurally vibrating in response to application of an alternating signal between the electrodes, a resin case having a supporting member disposed inside sidewalls of the case for supporting the diaphragm, terminals insert-molded in the case so as to have internal connections exposed in the supporting member and external connections exposed on the external surface of the case, a conductive adhesive for electrically connecting the electrodes of the diaphragm to the internal connections of the terminals, an elastic sealant for sealing a gap between the external periphery of the diaphragm and the internal periphery of the case, and a lid plate for closing an opening of the case. The terminals are pressed terminals, which are made by punching a metallic plate so that a flash-producing surface is to be the lower surface, and flashes on both respective side-edges of the internal connections are embedded inside the supporting member of the case so that the top surfaces of the internal connections are flush with the surface of the supporting member, and the external connections of the terminals are bent toward the bottom surface of the case via the side surfaces thereof.

摘要： [Problems to be solved]A communication cable and a communication wire protecting tube, which can be easily bent to a predetermined bend radius by a low force but which requires such a higher force for the bend of a smaller diameter that it may be hard to bend. [Means for solving the Problems]The communication cable 10,10A comprises a communication wire 11,11A and an armor 13A including at least two synthetic resin layers, and protects the communication wire 11,11A in a loose state. The communication wire protecting tube comprises at least two synthetic resin layers, and inserts the communication wire 11,11A in a loose state. The most hard resin layer 13a, 13aA of the armor 13,13A has a crosswise or spiral annular groove 14 or cut portion 14A continuous in the longitudinal direction to reach the radially inner face, and the outermost layer of the armor 13,13A is formed of a protective layer 13b,13bA made of a softer resin than the hard resin layer 13a, 13aA. The adjoining edge portions 14a,14aA of the annular groove 14 or the cut portion 14A come, when the communication wire 11,11A is to be bent, into contact with each other so that it may be prevented from being bent to a predetermined or smaller bend radius.
