Problems solved by technology

[0002] With the rapid arrival of the aging society, more and more elderly people appear in the society. For many families, there are old people at home, and often the old people live alone at home, and their children work outside. However, a considerable number of old people living alone have hearing loss, Unresponsive, and the existing landline telephones are generally designed for people with normal hearing, the ringing sound is small, and there is no light prompt
When the family calls, the elderly often cannot answer in time, which causes great difficulties in the communication between the children and the elderly, and sometimes causes the children to worry too much about the elderly's health, and sometimes delays the transmission of important information

Abstract

The invention provides an acousto-optic reminder of a fixed-line telephone, and belongs to the technical field of fixed-line telephone auxiliary equipment. A fixed-line telephone auxiliary device which enables the old to answer the phone timely and conveniently is provided. According to the technical scheme, two wiring terminals of a ringing loudspeaker of the fixed-line telephone are both connected with the input end of a rectifier diode through wires, the output end of the rectifier diode is connected with the input end of a filter capacitor, and the output end of the filter capacitor is connected with the input control end of a solid-state relay. The positive end of an AC power source is in series connection with one end of a switch, and the other end of the switch is in series connection with the first output load end of the solid-state relay. The second output load end of the solid-state relay is in series connection with one end of an indicating lamp, the other end of the indicating lamp is in series connection with the negative end of the AC power source, and the two ends of a high pitch loudspeaker are connected with the two ends of the indicating lamp in parallel. The acousto-optic reminder is applied to auxiliary work of the fixed-line telephone.

Description

technical field [0001] The utility model relates to an acousto-optic reminder for a fixed telephone, which belongs to the technical field of fixed telephone auxiliary equipment. Background technique [0002] With the rapid arrival of the aging society, more and more elderly people appear in the society. For many families, there are old people at home, and often the old people live alone at home and their children work outside. However, a considerable number of old people living alone have hearing loss, Unresponsive, and existing landline telephone generally all designs to the people of normal hearing, and ringing sound is relatively small, does not have light prompt. When the family calls, the elderly often cannot answer in time, which causes great difficulties in the communication between the children and the elderly, sometimes causes the children to worry too much about the elderly's health, and sometimes delays the transmission of important information.
