Abstract
The utility model discloses a telephone set, particularly a telephone set with a cordless headphone. The utility model comprises a hand free device, a microphone and a base set (1) provided with a high-frequency transmitting circuit. The utility model is characterized in that the utility model also comprises a cordless headphone (3) provided with a cordless receiving circuit for singly receiving transmitting signals of the base set of the telephone and a telescopic microphone (5) arranged on one side of the base set (1). Due to the adoption of a mode of single transmission by the base set and single reception by the cordless headphone, the utility model simplifies circuit structure and reduces cost and power consumption. The cordless headphone has the advantages of simple structure, simple circuit, low cost, hand free, portability, practicability, convenient operation, no curve limitation and high user propagation rate; the utility model can be used for communicating freely within a range of 1.5 meters at will.
Description
