    • A system for generating number tones for dialing a telephone device comprising a microphone. The system comprises a housing, a first data entry device, first and second memory devices, an output signal generator, and a transducer. The housing defines a sound opening. The first data entry device is supported by the housing and is associated with a first sequence of stored digits. The first memory device stores the first sequence of stored digits. The second memory device stores frequency data associated with number tones. The output signal generator generates, upon activation of the first data entry device, an output signal based on the first sequence of stored digits and the frequency data. The transducer is mounted within the housing adjacent to the sound opening and converts the output signal into an audible signal. The housing is adapted to be attached to the telephone device with the sound opening adjacent to the microphone.
    • 一种用于产生用于拨打包括麦克风的电话设备的号码音的系统。 该系统包括壳体,第一数据输入装置,第一和第二存储器装置,输出信号发生器和换能器。 外壳定义了一个声音开口。 第一个数据输入设备由外壳支持并与第一个存储数字序列相关联。 第一存储器件存储存储数字的第一序列。 第二存储器件存储与数字音调相关联的频率数据。 输出信号发生器在激活第一数据输入装置时产生基于存储数字的第一序列和频率数据的输出信号。 传感器安装在壳体内与声音开口相邻并将输出信号转换为可听见的信号。 壳体适于附接到具有与麦克风相邻的声音开口的电话设备。

    • A system for generating number tones for dialing a telephone device comprising a socket assembly and at least one dialer module. The socket assembly defines at least one socket, where the socket is electrically connected to the telephone device. The at least one dialer module comprises a first memory device for storing a sequence of numbers, a first data entry device and a plug electrically connected to the first memory device. The plug engages the socket to electrically connect the first memory device to the socket assembly. Operation of the first data entry device causes the generation of an electrical DTMF signal based on the sequence of numbers stored by the memory device. The electrical DTMF signal is transmitted to the telephone device.
    • 一种用于产生拨号电话的系统,用于拨打包括插座组件和至少一个拨号器模块的电话设备。 插座组件限定至少一个插座,其中插座电连接到电话设备。 所述至少一个拨号器模块包括用于存储数字序列的第一存储器设备,电连接到第一存储器设备的第一数据输入设备和插头。 插头接合插座以将第一存储器件电连接到插座组件。 第一数据输入装置的操作基于由存储装置存储的数字序列产生电DTMF信号。 电DTMF信号被传送到电话设备。

    • A system for generating number tones for dialing a telephone device. The system comprises a socket assembly, at least one button assembly, and a converter. The socket assembly defines at least one socket. Each button assembly comprises a memory device for storing a sequence of numbers and a switch device. The converter generates a DTMF signal comprising a sequence of DTMF tones. Operation of the switch device causes the converter to generate the DTMF signal based on the sequence of numbers stored by the memory device. The socket assembly electrically connects the converter to the telephone device.
    • 一种用于产生用于拨打电话设备的号码音的系统。 该系统包括插座组件,至少一个按钮组件和转换器。 插座组件至少定义一个插座。 每个按钮组件包括用于存储数字序列的存储器装置和开关装置。 该转换器产生一个DTMF​​信号,该DTMF信号包括一系列DTMF音调。 开关装置的操作使得转换器基于存储器件存储的数字顺序产生DTMF信号。 插座组件将转换器电连接到电话设备。
