    摘要: A speaker and a magnetic circuit for a speaker, in which the high quality sound is obtained, are provided using a structure which is thin, light-weight and symmetrical in the vibration direction. In three sheets of layered magnets, the first magnet of the first layer and the third magnet of the third layer are arranged in the magnetic directions which repel each other, and the polarity of second magnet of the second layer is arranged perpendicularly to the polarity of the first and third magnets of the first and third layers at the top and bottom thereof. A voice coil wound near the center of a voice coil bobbin is arranged to oppose the second magnet of the second layer of the magnetic circuit composed of the three layers, and the same vibration systems composed of the diaphragms and edges are connected to both the ends of this voice coil bobbin. Accordingly, the speaker which has a vibration system that is symmetrical with respect to a center axis X-X perpendicular to the direction of a center axis of a voice coil is obtained.

    摘要: A speaker apparatus which can remove undesirable vibrations and can produce sounds of excellent quality of acoustic signals having high audio frequencies is presented by increasing a strength of a flat joint portion and by properly setting a mass ratio between a central dome-like diaphragm and an edge-like diaphragm of a speaker diaphragm. This speaker apparatus includes a diaphragm portion in which a mass ratio of the edge-like diaphragm relative to the dome-like diaphragm falls within a predetermined range near 1 and a fixed portion at which a bobbin of a voice coil or an end face of a conductive one turn ring is bonded to and fixed to a flat portion for joining the dome-like diaphragm and the edge-like diaphragm so that mechanical strength of a joint flat portion of the diaphragms can be increased.

    摘要: An automatic disk selecting apparatus receives a plurality of storage cases in which disks are stored. The storage cases are arranged in the front portion of a body case, and are movable in the right and left directions. A player is arranged behind the body case and is movable back and forth, and right and left. One of the storage cases is selected by a disk selecting unit and is fixed, while the other storage cases are moved in the right and left directions to form a space for inserting the player. The player is moved into the space, and a disk stored in the selected storage case is clamped, thereby reproducing information recorded on the disk. The system is small in size, provides improved disk handling, and provides decreased access time.
