CONSTITUTION:A microphone 6 is attached to a sunvisor 5 and a speaker 8 is attached to a headrest 1a of a seat 1 via a flexible arm 10 and a rotary plate 9. Respective microphone 6 and speaker 8 are connected to a handset of automobile radiotelephone having a receiving unit and a sending unit via a cord 7 and so on. Owing to attachment of a hands-free set of speaker to a headrest portion of the seat, driving is not disturbed, and further, as the little volume will do, howling is not generated, too, therefore it is possible to make operationability and usage property good. |
