    • Apparatus includes a housing, the housing including a first body part and a second body part, the first body part being moveable relative to the second body part, wherein the housing has a first configuration when the first body part is in a first position relative to the second body part between and a second configuration when the first body part is in a second position relative to the second body part; and a speaker arrangement, wherein the speaker arrangement comprises a transducer, a front cavity coupled to a first side of the transducer, and an opening. The opening connects the front cavity to an exterior of the housing. A rear cavity is coupled to a second side of the transducer, the second side of the transducer being on an opposite side of the transducer to the first side of the transducer. The speaker arrangement has a first physical arrangement when the housing is in the first configuration and a second physical arrangement when the housing is in the second configuration, the first physical arrangement being different to the second physical arrangement.
    • 设备包括壳体,壳体包括第一主体部分和第二主体部分,第一主体部分可相对于第二主体部分移动,其中当第一主体部件相对于第一主体部件处于第一位置时,壳体具有第一构造 当第一主体部分相对于第二主体部分处于第二位置时,第二主体部分和第二构造之间; 以及扬声器装置,其中所述扬声器装置包括换能器,耦合到所述换能器的第一侧的前腔以及开口。 开口将前腔连接到外壳的外部。 后腔耦合到换能器的第二侧,换能器的第二侧位于换能器的相对侧至换能器的第一侧。 当壳体处于第一配置时,扬声器布置具有第一物理布置,并且当壳体处于第二配置时具有第二物理布置,第一物理布置不同于第二物理布置。

    • A method enables the introduction of a 200 kHz GSM-type network into a TDMA system having a bandwidth that is substantially less than a 2.5 MHz bandwidth normally employed for GSM-type networks. The method provides a 52-multiframe containing 12 blocks of four consecutive frames, two idle frames, and two control channels, and rotates the control channels belonging to a serving time group over odd timeslot numbers as 7, 5, 3, 1, 7, 5, . . . , etc. Preferably the rotation occurs between frame numbers (FN) mod 52=3 and 4. Information specifying at least the rotation direction is signalled to the mobile station in a downlink synchronization channel.
    • 一种方法能够将200kHz GSM型网络引入TDMA系统,该TDMA系统的带宽实质上小于通常用于GSM型网络的2.5MHz带宽。 该方法提供包含四个连续帧,两个空闲帧和两个控制信道的12个块的52-多帧,并且将属于服务时间组的控制信道在奇数时隙号上旋转为7,5,3,1,7, 5,。 。 。 等等。优选地,旋转发生在帧号(FN)mod 52 = 3和4之间。至少指定旋转方向的信息在下行链路同步信道中被通知给移动台。
