Telephone listening system enabling two person listening to incoming call

摘要

The two person listening system has a microphone (1) with flexible section (4) attached to a first listener's main telephone earpiece. Electrical signals representing the sounds are passed to an amplifier in a central box (5), and are subsequently coupled to an earpiece (3) in the ear of a second listener. The central box also has sticking notelets, on which important points can be recorded with a crayon (32). The box has attachment points on the side, and can be lit up. The amplifier preferably has a variable gain, which is adjustable by the user.
