    Abstract: There is provided an elongated loudspeaker having high sound quality that is unlikely to cause break-up resonances and is capable of obtaining flat frequency characteristics. The loudspeaker includes: an elongated flat-plate-shaped diaphragm; a frame having an opening portion larger than the diaphragm; an edge placed between an inner periphery of the frame around the opening portion and an outer periphery of the diaphragm and supporting and allowing the diaphragm to easily vibrate in an emission direction of sound waves; a coupling cone extending from a rear surface of the diaphragm and including two elongated portions arranged parallel to a longitudinal direction of the diaphragm, the coupling cone vibrating in conjunction with the diaphragm; a voice coil wound around at least the two elongated portions; and a magnetic circuit that imparts, to the voice coil, driving force for generating sound waves. A distance between the two elongated portions of the coupling cone is smaller at end positions than at root positions, the end positions being far from the rear surface of the diaphragm and the root positions being close to the rear surface. The two elongated portions are of such shapes and sizes that the entire two elongated portions are included within respective magnetic gaps of the magnetic circuit when the coupling cone vibrates in conjunction with the diaphragm, the entire two elongated portions extending from the root positions to the end positions, respectively.

    Abstract: PROBLEM TO BE SOLVED: To provide a transducer magnet for a low profile loudspeaker transducer having a voice coil, a surround suspension, a diaphragm, and a top plate.SOLUTION: The transducer magnet may include a first magnet assembly which may include an annular outer magnet having an outer perimeter, an outer diameter and an inner diameter. The inner diameter defines a vacant circular center within the annular outer magnet, and the difference in length between the diameter of the circular inner magnet and the inner diameter of the annular outer magnet defines an annular first magnet assembly air gap. The annular outer magnet includes one or more channels extending inwardly from the outer perimeter of the annular outer magnet to the first magnet assembly air gap configured to receive the voice coil. The channels are configured to pass hookup wires from the voice coil to an external device from the transducer magnet.

    Abstract translation: 要解决的问题：提供一种用于具有音圈，环绕悬架，隔膜和顶板的低调喇叭换能器的换能器磁体。 解决方案：换能器磁体可以包括第一磁体组件，其可以包括具有外周边，外径和内径的环形外磁体。 内径在环形外磁体内限定一个空的圆形中心，圆形内磁体的直径和环形外磁体的内径之间的长度差定义了环形的第一磁体组件气隙。 环形外磁体包括从环形外磁体的外周向内延伸到配置成接收音圈的第一磁体组件气隙的一个或多个通道。 通道被配置为将来自音圈的连接线从换能器磁体传递到外部设备。 版权所有（C）2013，JPO＆INPIT

    Abstract: 分割共振が起こりにくく平坦な周波数特性を得ることができる音質が優れた縦長のスピーカを提供する。平板形状で縦長の振動板と、振動板よりも大きな開口部を有するフレームと、開口部の内周と振動板の外周との間に位置し、振動板を音波の放射方向に振動容易に支持するエッジと、振動板の裏面から伸延し振動板と連動して振動する振動板の長手方向と平行に連なる2列の部分を有するカップリングコーンと、少なくとも2列の部分に巻回されたボイスコイルと、ボイスコイルに音波を発生させるための駆動力を与える磁気回路とを備える。カップリングコーンは、2列の部分の列間隔が振動板の裏面に近い根元位置よりも裏面から離れた先端位置の方が狭く、2列の部分の根元位置から先端位置までの全てが、振動板と連動して振動したときに磁気回路における磁気ギャップ内に納まる形状及びサイズである。
