Abstract: A speaker includes a body, a yoke, and two connectors. The body includes an outer periphery with a recessed section. The yoke is securely mounted around the body and engaged with the recessed section. Each connector includes a first end fixed to the yoke and a second end. Each connector is at a level not beyond an end face of the body when the speaker is in an assembled state. Thus, the speaker has a reduced height, which is particularly useful for electronic devices that have a trend in miniaturization.

Abstract translation: 扬声器包括主体，磁轭和两个连接器。 主体包括具有凹部的外周。 轭被牢固地安装在主体周围并与凹进部分接合。 每个连接器包括固定到轭的第一端和第二端。 当扬声器处于组装状态时，每个连接器处于不超过身体端面的水平面上。 因此，扬声器具有降低的高度，其对于具有小型化趋势的电子设备特别有用。

Abstract: A fluid transfer guiding/controlling device and an application system thereof. The guiding/controlling device is composed of a power transfer/distribution unit and a switch member. The power transfer/distribution unit has a first chamber and a second chamber. At least one bypass flow ways are disposed in the first chamber. Stop sections are disposed in the second chamber. Communication notches are disposed in adjacency to the stop sections in communication with an outer side. The switch member having an internal flow guide passage and a first flow guide window and a second flow guide window is disposed in the first and second chambers. The first flow guide window is switchable between the bypass flow ways. The second flow guide window is moved from the stop section to pass through a corresponding communication notch, whereby part of the fluid in the flow guide passage flows through the communication notch.

Abstract: A dual magnetic loop type receiver is composed of a yoke molding, a ferrite yoke, an annular magnet, a magnetic pole member, a vibration panel, a ferrite core, and a circular plate. While the receiver is operated, the annular magnet and the ferrite core and the ferrite yoke cause the receiver to produce an inner magnetic loop that interacts with the inner voice coil, and an outer magnetic loop that interacts with the outer voice coil such that the receiver generates vibration and sound.
