摘要： An electricity-to-sound transducer has a diaphragm having an asymmetric shape which is flat when viewed from a direction of vibration, with major and minor axes, having continuous curvatures of concavity and convexity in a direction of sound irradiation, provided with a slot formed almost at a center of the diaphragm in a direction perpendicular to a longitudinal direction of the diaphragm. An edge portion is formed as surrounding an outer periphery of the diaphragm, an inner section of the edge portion being connected to the outer periphery, the edge portion sustaining the diaphragm so that it can vibrate. A voice coil bobbin has a winding portion around which a voice coil is wound split into two portions in the longitudinal direction of the diaphragm, the bobbin being attached to a rear surface of the diaphragm while the two portions are joined to each other, the joined portions forming a reinforcing beam that reaches a rear surface of a bottom of the slot of the diaphragm. The voice coil is applied flux by a magnetic circuit for vibration. The outer periphery of the edge portion and the magnetic circuit are sustained by a frame. Another type of transducer also has a diaphragm and a voice coil bobbin. A slot of the diaphragm has walls on a bottom of slot, on both ends of the slot in a direction of the major axis and on both ends of the slot in a direction of the minor axis, the slot protruding in a direction of a rear surface of the diaphragm to form a protrusion. The voice coil bobbin is attached to the rear surface of the diaphragm, an inner size of the bobbin almost at the center in the longitudinal direction being larger than an outer size of the protrusion in the direction of the minor axis, the protrusion being inserted into the bobbin, a gap between an inner wall of the bobbin and the protrusion being filled with an adhesive so that the protrusion and the bobbin are bonded to each other.
摘要翻译：电声转换器具有非对称形状的振动膜，当从振动方向观察时，该振动膜具有长轴和短轴，在声音辐射方向上具有凹凸的连续曲率，设有形成的槽几乎在与隔膜的纵向垂直的方向上隔膜的中心处。边缘部分形成为围绕振动膜的外周边，边缘部分的内部分连接到外周边，边缘部分支撑振动膜以使其振动。音圈骨架具有缠绕音圈的缠绕部分，缠绕音圈的部分在振动膜的纵向上分成两部分，线圈架连接到振动膜的后表面，同时两部分彼此连接，连接形成加强梁的部分到达隔膜槽的底部的后表面。音圈通过磁路施加磁通以振动。边缘部分的外围和磁路由框架支撑。另一种类型的换能器也有一个振膜和一个音圈线轴。隔膜的缝隙在缝隙的底部具有壁，缝隙在长轴方向上的两端上以及缝隙在短轴方向上的两端上，缝隙沿着后部方向隔膜的表面形成突起。音圈骨架安装在振动板的背面，大致位于长度方向中央的线圈骨架的内径尺寸大于短轴方向的突起的外径尺寸，突起插入线轴，线轴的内壁与突起之间的间隙填充有粘合剂，使得突起与线轴相互结合。

摘要： By forming a flange portion 16a1 protruding inward in the radial direction at an upper end portion 16a of a voice coil 16, a coiling sectional shape of the voice coil 16 is set to a L-shape. And, the upper end portion 16a of this voice coil 16 is bonded and fixed to a central flat portion 12b of a diaphragm 12. Hereby, by only increasing slightly the weight of the usual voice coil having an I-shaped coiling section, the large bonding area can be obtained between the voice coil 16 and the diaphragm 12, so that separation of the voice coil 16 can be prevented. Further, since other portions of the voice coil 16 than the upper end portion 16a thereof have the usual coil thickness, it is not necessary to expand the width of a cylindrical magnetic gap G in a magnetic circuit unit 18, whereby it is prevented that electroacoustic conversion efficiency of a speaker 10 lowers.
摘要翻译：通过形成在音圈16的上端部16a沿径向向内突出的凸缘部16a1，将音圈16的卷绕截面形状设定为L字形。并且，该音圈16的上端部16a被接合并固定在振动板12的中央平坦部12b上。因此，通过仅轻微地增加具有I形卷绕部的通常的音圈的重量，可以在音圈16和隔膜12之间获得接合面积，从而可以防止音圈16的分离。此外，由于音圈16的其他部分比其上端部16a具有通常的线圈厚度，因此不需要在磁路单元18中扩大圆柱形磁隙G的宽度，从而防止电声扬声器10的转换效率降低。

摘要： Gemäß dem Stand der Technik werden hochtemperaturfeste Zentrierungen von Lautsprechern so ausgebildet, daß eine mit dem Polkern (14) verbundene Stange (17) als Führung für eine mit dem Schwingspulenträger (11) verbundenen Hülse (19) dient. Eine derartige Zentrierung erfordert aber einen engen Abstand zwischen der Stange (17) und der auf ihr gleitend angeordneten Hülse (19). Dieser enge Abstand zwischen den beiden eben genannten Teilen führt dazu, daß bei Hubbewegungen des Schwingspulenträgers (11) die Stange (17) und die Hülse (19) aneinander reiben, womit die freie Bewegung des Schwingspulenträgers (11) gebremst bzw. die Wiedergabe des Lautsprechers verschlechtert wird. Daher lag der Erfindung die Aufgabe zugrunde eine hochtemperaturfeste Zentrierung für Lautsprecher anzugeben, bei welcher eine Berührung von Stange (17) und Hülse (19) ausgeschloßen ist. Erfindungsgemäß wird vorgeschlagen, die Stange (17) und die Hülse (19) aus Magnetmaterial zu bilden und dieses Material radial zur Lautsprecherachse (16) zu magnetisieren. Wiesen die einander zugewandten magnetischen Bereiche von Hülse (19) und Stange (17) die gleiche Polung auf, wird durch die gegenseitige Abstoßung eine berührungslose Zentrierung der Hülse (19) auf der Stange (17) erreicht. Ist der Verbindungsbereich von Schwingspulenträger (11) und Lautsprechermembran (10) auf der Innenseite des Schwingspulenträgers (11) mit der Hülse (19) versehen und wird der Außenmantel (28) der Lautsprechermembran (10, 29) mit einem Klemmring (27) versehen, kann der Klemmring (27) zur Verbindung der Teile (19, 10, 11) miteinander genutzt werden, ohne daß die Verwendung von Klebstoff notwendig ist.

摘要： A loudspeaker assembly for low frequency reproduction having a good vibration efficiency for a large vibration amplitude and a small magnetic distortion. Two magnets magnetized in the direction of thickness have the magnetic poles of the same polarity disposed facing each other with a center plate made of soft magnetic material being interposed therebetween. Magnetic fluxes extend from the outer periphery (positive side) of the center plate and return to the top and bottom surfaces (negative side) of the two magnets. The winding width of a voice coil is set equal to or greater than a width between two transition points of the magnetic flux distribution from the positive side to the negative side.

摘要： The straight-sided cone or diaphragm (2) of a moving coil loudspeaker is formed wholly or principally from aluminium which is spun substantially to double its tensile strength, the spinning process being conventional and preferably being effected manually (Fig. 1). Most advantageously, the formed cone (2) is hard anodised on both sides to increase rigidity and heat radiation. A loudspeaker in accordance with the invention has approximately two and one third times the sound volume capacity of a conventional loudspeaker of comparable size without producing any detectable sound distortion.
