    • A speech voice input to the microphone 62 is converted into a digital signal by an A/D converter 35. An encoder 36 in turn spreads the digital signal using a spread spectrum scheme and the spread signal is supplied to the modulator 37. A modulator 37 modulates a carrier wave (e.g., a frequency of 800 MHz) with the spread signal and the modulated wave is transmitted from an antenna 40. A high-frequency signal is induced in a paired cable 64 of a headset 60 by the transmitted wave. The high-frequency signal transferred in the direction to the telephone unit 30 through the cable 64 is eliminated by an LPF 46. On the other hand, the high-frequency signal transferred to a headphone 61 passes through a capacitor 63 to a ground level. Thus, the entry of the transmitted signal into the amplifier 45 and the headphone 61 can be avoided, and an occurrence of noise in the headphone 61 can be prevented.
    • 输入到麦克风62的语音通过A / D转换器35转换为数字信号。编码器36又使用扩频方案扩展数字信号,并将扩展信号提供给调制器37.调制器37 利用扩展信号调制载波(例如,800MHz的频率),并且从天线40发送调制波。通过发射波在耳机60的配对电缆64中感应出高频信号。 通过电缆64向电话单元30的方向传送的高频信号由LPF46消除。另一方面,传送到耳机61的高频信号通过电容器63到达地电平。 因此,可以避免将发送的信号输入到放大器45和耳机61,并且可以防止耳机61中的噪声的发生。

    • Disclosed herein is a protector for wire harness, which comprises a first protector body for protectively covering a first wire harness to be secured therein and a second protector body for protectively covering a second wire harness to be optionally secured therein. The second protector body having a substantially L-like shape in cross section. The second body is pivotally coupled with the first protector body through a hinge member so as to enable pivotal movement of the second protector body with respect to the first protector body. The protector further comprises a plurality of supporting pieces for supporting the second wire harness thereon which may be secured in addition to the first wire harness. The supporting pieces are provided on the first protector body so as to secure the second wire harness in cooperation with the second protector body.
    • 这里公开了一种用于线束的保护器,其包括用于保护性地覆盖要固定在其中的第一线束的第一保护器主体和用于保护性地覆盖第二线束以可选地固定在其中的第二保护器本体。 第二保护体在横截面上具有大致L形的形状。 第二主体通过铰链构件与第一保护体本体枢转联接,以使第二保护体相对于第一保护体能够枢转运动。 保护器还包括用于支撑除了第一线束之外的第二线束的多个支撑件。 支撑件设置在第一保护器主体上,以便与第二保护器主体协作地固定第二线束。
