    摘要： A piezoelectric speaker comprises a plurality of diaphragms, connecting components, and piezoelectric elements. The plurality of diaphragms are each formed by a laminated material in which a core layer made of an insulating material is laminated to skin layers each made of a conductive material so as to form the skin layers on both surfaces of the core layer. The connecting components each corresponds to a plate-shaped component of the insulating material and connects between at least two of the plurality of diaphragms. Piezoelectric elements are mounted on surfaces of the plurality of diaphragms, respectively. The plurality of diaphragms are insulated from each other such that separate voltages are applied to the piezoelectric elements mounted thereon, respectively.

    摘要： A piezoelectric speaker improved in acoustic features by weight reduction of a diaphragm of the piezoelectric speaker without decreasing stiffness of the diaphragm or a coefficient of thermal expansion of surfaces of the piezoelectric speaker is provided. The diaphragm having placed thereon a piezoelectric element is made of a sandwich-laminate clad material using different materials. For example, surface materials made of 42 alloy each having a thickness of 10 μm and a core material made of aluminium having a thickness of 30 μm form a clad material having a thickness of 50 μm. The formed clad material is processed into an arbitrary shape to form the diaphragm of the piezoelectric speaker. With this diaphragm, it is possible to keep the stiffness and the coefficient of thermal expansion of the 42-alloy diaphragm having the thickness of 50 μm, and also achieve weight reduction by approximately 40%.

    摘要： An acoustic diaphragm for speakers having a sandwich structure constituted by a core material comprising an elongated web material bent to have a plurality of radial projections, and upper and lower surface members adhered to the upper and lower edges of the core member, as well as a method of producing the same. The acoustic diaphragm of the invention has a reduced weight while exhibiting a large flexural rigidity so that the nodal line during the resonance vibration can have a circular form which in turn offers a circular form of nodal line and increased speaker power. Also, the method of producing the invention permits easy fabrication of the acoustic diaphragm having a sandwich structure.

    摘要： A diaphragm for speakers comprises a self-support, shaped body including a tightly woven synthetic polymer fiber cloth substrate which has at least a diaphragm portion and edge portion shaped integrally with and extending from the diaphragm portion. The diaphragm portion of the cloth substrate had a polymer resin at least partially impregnated therein and the edge portion has a relatively flexible polymer material at least partially impregnated therein so that the edge portion is lower in stiffness than the diaphragm portion. The diaphragm-edge integral molding is fabricated by applying the respective types of polymers to the diaphragm and edge portions of the cloth substrate and subjecting the applied substrate to hot pressing in a mold capable of forming the integral molding. When applied as dynamic speakers, the integral molding exhibits a broad frequency band, low distortion rates and high sound quality. The stiffness difference between the diaphragm and edge portions may be created by using one type of thermoplastic resin which is applied to the diaphragm and edge portions in different amounts.
