    摘要： The present invention provides such a vibration generator which can obtain desired power-generation efficiency even if the vibration frequency is low. A vibration generator is provided with a vibrator which includes a plurality of magnets whose same magnetic poles are arranged by being faced to one another and which vibrates by a predetermined resonant frequency; a coil spring which supports the vibrator falling toward the gravitational direction and concurrently which vibrates the vibrator by a predetermined resonant frequency; a tubular winding bobbin in the inside of which the vibrator and the coil spring vibrate; coils which are wound on the outer circumference of the winding bobbin and which are connected in series inside groups divided into two or more; and a plurality of rectification circuits, each of which rectifies the output voltages of the coils for every one of the groups.

    摘要： An electronic component comprises: a magnetic core having a flat base and a core, the flat base having a top, a bottom, and first and second opposite sides, the core is on the top; a winding having an edgewise coil including a wound flat wire and the core, the winding having two non-wound flat wires extending therefrom; and a magnetic exterior body covering the core and the edgewise coil. The two non-wound flat wires extend along the top, the first side, the bottom and then the second side, and the two non-wound flat wires are non-adhesively positioned around the flat base. The two non-wound flat wires on the bottom are externally exposed electrodes. The second side inclines towards the core. The two ends of the two non-wound flat wires are embedded into the magnetic exterior body to fix the two non-wound flat wires to the magnetic exterior body.

    摘要： An electronic component includes a magnetic core member, a winding and a magnetic exterior body. The magnetic core member has a flat base and a core. The flat base has a top surface, a bottom surface, a first side surface and a second side surface opposite to the first side surface. The core is located on the top surface of the flat base. A winding has an edgewise coil and two non-wound flat wires that extend from the edgewise coil. A magnetic exterior body covers at least the core and the edgewise coil. The two non-wound flat wires continuously extend along the top surface, the first side surface, the bottom surface and the second side surface of the flat base in this order. The two non-wound flat wires located on the bottom surface work as electrodes.
