    • A portable electronic device such as a handheld electronic device is provided. The device may have upper and lower portions. The upper portion may have clips that attach to springs on the lower portion. The device may have a housing with a bezel. A prong on the springs may ground the bezel. A vibrator mounting bracket may hold a vibrator in place within the housing. The vibrator mounting bracket may have an end that engages the housing. A threaded insert may be welded to the spring. A screw that passes through a hole in the vibrator mounting bracket may be screwed into the threaded insert to attach the vibrator to the housing. An elastomeric member may bias the vibrator towards the bracket. An acoustic module may serve as a subassembly for the device. Components such as an antenna, dock connector, microphone, and speaker may be attached to the acoustic module.
    • 提供诸如手持电子设备的便携式电子设备。 该装置可以具有上部和下部。 上部可以具有附接到下部的弹簧的夹子。 该装置可以具有带有挡板的外壳。 弹簧上的插脚可能会挡住挡板。 振动器安装支架可将振动器固定在壳体内的适当位置。 振动器安装支架可以具有接合壳体的端部。 螺纹插入件可以焊接到弹簧。 穿过振动器安装支架中的孔的螺钉可以拧入螺纹插入件中,以将振动器附接到壳体。 弹性体构件可将振动器朝向支架偏置。 声学模块可以用作该装置的子组件。 诸如天线,坞站连接器,麦克风和扬声器的组件可以附接到声学模块。

    • In the on-hook state of a set of telephone line-switch contacts (LS-1 to LS-5), an incoming low-frequency ringing signal (A) from the central office is rectified (14) and applied to an oscillator circuit (16), which drives the receiver (11) of the telephone handset (21) as the transducer for the tone ringer. A protective switch (20) is used to disable the oscillator circuit from producing an output to the receiver whenever the handset has been lifted from the cradle (22), so as to prevent the user from being rung in the ear if the handset is removed from the cradle and the line switch is thereafter depressed manually while the handset is in the normal listening position. The switch responds to the physical presence of the handset in the cradle, such as by using a magnetically actuated switch mounted in the cradle and operated by a magnet (24) mounted in the facing surface of the handset.
    • 在一组电话线路开关触点(LS-1至LS-5)的挂机状态下,来自中心局的输入低频振铃信号(A)被整流(14)并施加到振荡器电路 (16),其驱动电话听筒(21)的接收器(11)作为音调铃声的换能器。 保护开关(20)用于在手机已经从托架(22)提升时,使振荡器电路不产生输出到接收器,以便如果手机被移除,则防止用户在耳朵中横摇 然后在手机处于正常收听位置时,从托架中切换线路开关,然后手动按下。 开关响应手机在托架中的物理存在,例如通过使用安装在托架中的磁力驱动的开关并由安装在手机的相对表面中的磁体(24)来操作。

    • A location model updating apparatus generates attribute data including an attribute of a location and an attribute between locations. A peripheral location is extracted by including each location from a current location of a terminal apparatus to a first front as a member of a definite peripheral location list, including each location from the first front to a second front as a member of a candidate peripheral location list, and updating each location that is a member of the definite peripheral location list and exists from the current location to the first front, and each location that is a member of the candidate peripheral location list and exists from the first front to the second front, using the current location of the terminal apparatus as a query. Data of a peripheral location model of the extracted peripheral location is transmitted to the terminal apparatus.
    • 位置模型更新装置生成包括位置的属性和位置之间的属性的属性数据。 通过将每个位置从终端装置的当前位置包括到第一前部作为确定的周边位置列表的成员来提取外围位置,其包括作为候选周边位置的成员的从第一前端到第二前方的每个位置 列表,并且更新作为确定的周边位置列表的成员的每个位置,并且从当前位置到第一前方以及作为候选周边位置列表的成员的每个位置存在并且从第一前端到第二前端 ,使用终端设备的当前位置作为查询。 所提取的外围位置的外围位置模型的数据被发送到终端装置。
