A transmitter configured such that the number of degrees of freedom of the acoustic vibration system is two or more by attaching an electroacoustic conversion unit to the mouthpiece of a handset equipped with a mouthpiece. In the method, the electroacoustic conversion unit is attached via a flexible member while securing a certain volume between the electroacoustic conversion unit and the inner surface of the mouthpiece, and the mass of the electroacoustic conversion unit and the A transmitter characterized in that the lowest resonant frequency realized by the flexible member is set to a frequency lower than a telephone band. 2 Utility Model Registration Claims Claim 1, wherein the flexible member comprises a support part for the electroacoustic conversion unit, a mounting part to the inner surface of the mouthpiece, and a coupling part between the mounting part and the support part, A transmitter characterized in that these are integrally formed. 3. In claim 2 of the utility model registration claim, a stepped portion is formed on the side surface of the electroacoustic transducer unit, and a groove that fits into the stepped portion is formed in the support portion of the electroacoustic converter unit provided on the flexible member. A transmitter characterized by:
