    • A loudspeaker incorporates features to improve performance and quality while reducing component and manufacturing costs. One embodiment of a loudspeaker has a frame with a generic mounting edge that mates with a secondary mounting component. The frame and mounting component are separated by an outer section of the diaphragm suspension annulus that provides vibration isolation. An additional outer section of the annulus can serve as a gasket to the mounting structure. Other embodiments have a plastic frame with an integrally molded spider, and a spider molded with individual legs that provides better control of the restorative force characteristic. The spider may also incorporate more than one plane of lateral stiffness to reduce a tendency for a voice coil to rock.
    • 扬声器集成了功能,以提高性能和质量,同时降低组件和制造成本。 扬声器的一个实施例具有与通常的安装边缘相配合的辅助安装部件的框架。 框架和安装部件由提供隔振的隔膜悬挂环的外部分隔开。 环的另外的外部部分可以用作安装结构的垫圈。 其他实施例具有带有整体模制的蜘蛛的塑料框架,并且具有单独腿的模制的蜘蛛,其提供对恢复力特性的更好控制。 蜘蛛还可以包括多于一个横向刚度的平面,以减少音圈摇摆的倾向。

    • A method for creating spatially resolved audio signals for a listener (18) that are representative of one or more callers (12, 14, 16). A digital data signal (13) that represents an individual caller's voice (12) contains an embedded tag (24) that is identifiable with the caller. The digital data signal is transmitted from a sending device at the caller's location to a receiving device (30) at the listener's location. At the receiving device, the tag is used to associate the digital data signal with a head related transfer function (32) that is resident preferably in a lookup table of the receiving device. The digital data stream is then convolved (34) with the associated head related transfer function to form a binaural digital signal that is ported to two or more acoustic transducers (36) to create analog audio signals that appear to emanate from different spatial locations around the listener.
    • 一种用于为代表一个或多个呼叫者(12,14,16)的收听者(18)创建空间解析音频信号的方法。 表示个人呼叫者的语音(12)的数字数据信号(13)包含可与呼叫者识别的嵌入式标签(24)。 数字数据信号从呼叫者的位置处的发送设备被发送到在收听者位置处的接收设备(30)。 在接收设备处,标签用于将数字数据信号与优先在该接收设备的查找表中驻留的头部相关传送功能(32)相关联。 然后将数字数据流与相关联的头部相关传递函数进行卷积(34)以形成双耳数字信号,该双耳数字信号被移植到两个或更多个声换能器(36),以产生模拟音频信号,其似乎从围绕 监听器。
