摘要： Gemäß dem Stand der Technik werden die Lautsprechermembran 10 und der Schwingspulenträger 11 zumeist durch Klebstoff verbunden. Sollen derartige Lautsprecher jedoch Dauerbetriebstemperaturen von weit über 120 Grad Celsius ausgesetzt werden, versagen selbst hochwertige Klebstoffe. Auch sind der einstückigen Ausbildung von Lautsprechermembran 10 und Schwingspulenträger 11 Grenzen gesetzt. Insbesondere ist es nicht in einfacher Weise möglich, aus Metall gebildete einstückige Anordnungen unter Anwendung von Tiefziehprozessen auszubilden. Daher liegt der Erfindung die Aufgabe zu Grunde, eine Verbindung von Schwingspulenträger 11 und Lautsprechermembran 11 anzugeben, welche einfach herstellbar ist, hochtemperatur belastet werden kann und klebstoffrei ist. Diese Aufgabe wird dadurch gelöst, daß der obere Rand 19 des Schwingspulenträgers 11 mit dem oberen Rand 16 eines an der Membran 10 ausgebildeten Halses 12 zusammengebördelt ist. Daneben wird angegeben, den Hals 12 der Lautsprechermembran 10 mit dem Schwingspulenträger 11 durch die Wirkung eines ringförmigen Teils 23 zu verbinden. Ist der Hals 12 der Membran 10 zwischen dem ringförmigen Teil 23 und dem Schwingspulenträger angeordnet, hat der Schwingspulenträger 11 die Funktion eines Widerlagers für die von dem ringförmigen Teil 23 auf den Außenmantel des Halses 12 ausgeübte Preßkraft.
摘要翻译：根据现有技术，扬声器振动膜片10和音圈骨架11通常通过粘合剂连接。但是，如果这些扬声器暴露在高于120摄氏度的连续工作温度下，即使是高质量的粘合剂也会失效。而且，扬声器振膜10和音圈骨架11的整体式设计也受到限制。特别是，使用深拉伸工艺不可能形成整体形成的金属组件。因此，本发明的目的是提供一种容易制造的音圈架11和扬声器振动膜11的组合物，该组合物可以在高温下装载并且不含粘合剂。该目的通过音圈架11的上边缘19与在膜10颈部12上形成的上边缘16压接而实现。另外，声称通过环形部分23的作用将扬声器振动膜10的颈部12与音圈骨架11连接。如果环形部件23和设置在所述音圈骨架之间的隔膜10的颈部12中，声音线圈线轴11具有用于通过环形部分23上的颈部按压力的外护套12上施加的力的抵接的功能。

摘要： An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular embodiment, the audio demonstration kit includes a paper speaker and instructions. The paper speaker includes a backplate, a suspension, and a diaphragm cut from a single sheet of paper. The demonstration kit may feature an amplifier that is configurable to accommodate various hardware additions as a child is ready for more progressively challenging construction. For example, the amplifier of an embodiment allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an embodiment is synchronized with the strobe light and a moveable platform to create the impression of that jiggling figures attached to the table are dancing. Interfaces with smart phone, recording, and other technologies further enhances and encourages the learning experience.
摘要翻译：音频演示套件鼓励孩子们通过构建和学习音箱性能来理解音频概念。在特定实施例中，音频演示套件包括纸扬声器和说明书。纸扬声器包括背板，悬架和从一张纸上切下的隔膜。该演示套件可配备一个可配置的放大器，以适应不同的硬件添加，因为孩子已准备好迎接更具挑战性的构造。例如，实施例的放大器允许单模和双模操作，以及驱动旋转马达并与闪光灯配合。一个实施例的放大器与闪光灯和可移动平台同步，以产生附着在桌子上的摇摆人物正在跳舞的印象。与智能手机，录音和其他技术的接口进一步增强和鼓励学习体验。
