Abstract

People with certain types of hearing loss can experience difficulty in hearing particular frequencies of sound-the tones that produce the ring in certain telephone devices can fall within a band of frequencies that are difficult for some of these people to hear. Thus, some telephones do not get the attention of the user when they ring. In the current invention, a telephone is provided with a ringer circuit that generates ring tones at several different base frequencies. In this manner, the user of the telephone can select from among the available frequencies to maximize his or her ability to hear the telephone ring.

TELEPHONE WITH RINGER FREQUENCY CONTROL FOR H EARING IMPAIRED

Invention by: Jerry Miller

People with certain types of hearing loss can experience difficulty in hearing particular frequencies of sound-the tones that produce the ring in certain telephone devices can fall within a band of frequencies that are difficult for some of these people to hear. Thus, some telephones do not get the attention of the user when they ring. In the current invention, a telephone is provided with a ringer circuit that generates ring tones at several different base frequencies. In this manner, the user of the telephone can select from among the available frequencies to maximize his or her ability to hear the telephone ring.

The varied frequency ringing function can be implemented either with software control or through the use of a multi-position switch that has settings for each available ring frequency. The frequency can be controlled either by switching in or out various components which alter the frequency of an oscillator, or by setting a divider in a frequency synthesizer. Other techniques for adjusting the frequency will occur to those skilled in design of electronic circuits.
