Abstract
A sound baffle attached to a telephone handset comprises a pair of telescopically connected members shaped and dimensioned to act as a sound guide in combination with a reflecting cover plate that can be obliquely adjusted to direct the sound waves emitted by the user toward the handset microphone, and to muffle his conversation to the surroundings for improved privacy.

A baffle used in connection with a portable telephone handset having a front panel, back panel, opposite lateral walls and a microphone positioned in a lower, distal section of said front panel, said baffle comprising:
- a first cradle shaving a first bottom plate substantially commensurate and contiguous to said back panel, and a first pair of side rails projecting from lateral edges of said bottom plate against said lateral walls;
- a second cradle having a second bottom plate and a second pair of side rails wrapped around said first bottom plate and first pair of side rails;
- means for slidingly securing said second cradle to said first cradle;
- a cover plate;
- and
- means for hingedly connecting a proximal portion of said cover plate to a distal portion of said second cradle;
- whereby said second cradle can be extended distally from said first cradle and said cover plate can be obliquely oriented in relation to said second cradle to form a reflector and angular channel for guiding sound waves emitted by a user of said handset toward said distal section and microphone.
The combination of a portable telephone handset and a foldable, open-top channel-shaped sound wave guide removably attached to said handset.
The combination of a portable voice communication handset with a voice muffler, said voice muffler comprising at least two componetns extendably connected to be collapsed, in a first position, around said handset and deployed, in a second position, to form a cup about a user's mouth.
