Abstract A radio telephone apparatus for transmitting and receiving information signals as electrical waves includes a main body section (1) towards one end of which a speaker unit (8) is enclosed. A battery casing (15) accommodating a battery which is adapted for supplying the power to the main body section (1) is detachably mounted on the other end of the main body section to reduce the size and the thickness of the apparatus. A ringer device is enclosed within the battery casing so that the acoustic sound emitted by the ringer is prevented from reaching the user's auditory which is in the vicinity of the speaker unit (8).
