    • According to one embodiment, a speaker comprises a frame, a drive source attached to the frame, which converts an electric signal into mechanical vibration, a diaphragm coupled to the drive source, which emits an acoustic wave corresponding to the mechanical vibration, and an attachment structure coupled to a predetermined portion (field unit attachment face) of the frame, which has a flange at a position remote from the predetermined portion. The attachment structure has predetermined compliance in a direction of vibration of the diaphragm, and which has predetermined stiffness in a direction substantially orthogonal to the direction of vibration of the diaphragm.
    • 根据一个实施例,扬声器包括框架,附接到框架的驱动源,其将电信号转换成机械振动;耦合到驱动源的隔膜,其发射对应于机械振动的声波;以及附件 结构耦合到框架的预定部分(现场单元附接面),其在远离预定部分的位置具有凸缘。 附接结构在隔膜的振动方向上具有预定的顺应性,并且在与振动膜的振动方向大致正交的方向上具有预定的刚度。

    • A number of sets of software may be systematically distributed and maintained via a network connecting many vendors and users of client/server software. A client program in a user computer detects when software subject to maintenance is activated and transmits an inquiry over the network to the software vendor's computer for information on the current version of the software. The server program compares data in the inquiry with data relating to the latest version of the software and returns update instruction information and updated software if appropriate. The client program automatically updates the software to the latest version according to the update instruction information when it is received. The client program can also send inquires at predetermined times, or in response to a user command. The inquiry can include a request for purchase information in which case the server checks qualifications of the user, processes the inquiry according to vendor management data and returns the requested software, if appropriate. Other inquiries can also be made in response to user commands or automatically, e.g., to obtain information on the most recent version and transmission of data from client to server in response to an abnormal termination of client software.
    • 可以通过连接许多客户端/服务器软件的供应商和用户的网络来系统地分发和维护多组软件。 用户计算机中的客户端程序检测何时激活维护的软件,并通过网络向软件供应商的计算机发送关于当前版本的软件的信息的查询。 服务器程序将查询中的数据与最新版本的软件相关的数据进行比较,并在适当的情况下返回更新指令信息和更新的软件。 客户端程序根据接收到的更新指令信息自动将软件更新为最新版本。 客户端程序还可以在预定时间或响应于用户命令发送查询。 查询可以包括购买信息请求,在这种情况下,服务器检查用户的资格,根据供应商管理数据处理查询,并在适当时返回所请求的软件。 还可以响应于用户命令或者自动地进行其他查询,例如,响应于客户端软件的异常终止,获得关于最新版本的信息和从客户端到服务器的数据传输。
