    • A modular housing system (100) comprises a first housing unit (102), a second housing unit (104), and a clamp (600). The first housing unit (102) has a first bottom wall (610) and a first side wall (108). The second housing unit (104) has a second bottom wall (612) and a second side wall (116). The first housing unit (102) defines a first channel (702) which borders the first side wall (108) and includes an first opening (703) along the first bottom wall (610). The second housing unit (104) defines a second channel which borders the second side wall (116) and includes a second opening along the second bottom wall (612). The clamp (600) has a longitudinally extending U-shape defining a base (800), a first attachment wall (802), and a second attachment wall (804). For optionally attaching the first and second housing units (102, 104), the first attachment wall (802) insertably attaches within the first channel (702) and the second attachment wall (804) insertably attaches within the second channel.
    • 模块化壳体系统(100)包括第一壳体单元(102),第二壳体单元(104)和夹具(600)。 第一壳体单元(102)具有第一底壁(610)和第一侧壁(108)。 第二壳体单元(104)具有第二底壁(612)和第二侧壁(116)。 第一壳体单元(102)限定与第一侧壁(108)接合并且包括沿着第一底壁(610)的第一开口(703)的第一通道(702)。 第二壳体单元(104)限定与第二侧壁(116)接合并且包括沿着第二底壁(612)的第二开口的第二通道。 夹具(600)具有限定基部(800),第一附接壁(802)和第二附接壁(804)的纵向延伸的U形形状。 为了可选地附接第一和第二壳体单元(102,104),第一附接壁(802)可插入地附接在第一通道(702)内,并且第二附接壁(804)可插入地附接在第二通道内。

    • A method (200) for controlling audio signals to an FM transmitter and a loudspeaker of a hands-free adapter first sends a first audio signal to the loudspeaker (242) and measures and records a loudspeaker audible artifact such as echo return loss (244) and/or echo tail length (246). Next, the hands-free adapter sends a second audio signal to the FM transmitter and the loudspeaker (252) and measures and records an FM transmitter and loudspeaker audible artifact such as echo return loss (254) and/or echo tail length (256). If the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is greater than a threshold (263, 266), the hands-free adapter sends a third audio signal to the FM transmitter only (270), and if the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is not greater than the threshold, the hands-free adapter sends the third audio signal to both the FM transmitter and the loudspeaker (280).
    • 一种用于控制FM发射机和免提适配器的扬声器的音频信号的方法(200)首先向扬声器(242)发送第一音频信号,并测量和记录扬声器可听见的伪影,例如回波损耗(244) 和/或回波尾长度(246)。 接下来,免提适配器向FM发射器和扬声器(252)发送第二音频信号,并测量并记录FM发射器和扬声器诸如回波返回损耗(254)和/或回波尾长度(256)的可听见的伪影, 。 如果FM发射器和扬声器的声音伪影减去扬声器的声音伪像大于阈值(263,266),则免提适配器仅向FM发射器发送第三音频信号(270),如果FM发射器和扬声器 可听见的人造物减去扬声器的声音伪影不大于阈值,免提适配器将第三音频信号发送到FM发射机和扬声器(280)。
