Abstract
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.
