Abstract
This electric artificial larynx 1 comprises a sound source generating unit 3 which is held by interposition means 2 attached directly or indirectly to the human body 10 and can be always placed near the cervical region 10a and a portable controller 4 which is separated from the sound source generating unit 3 and operates the sound source generating unit 3. The controller 4 preferably comprises a control signal generating unit which includes a sensor for detecting ID biological information or a switch 12 for supplying a signal and a control unit 16 which drives and controls the sound source generating unit 3 in response to a signal from the control signal generating unit and has a power source unit 15 for supplying power to the sound source generating unit 3. The sound source generating unit 3 may be caused to output a sound using sound source data based on the voice data of an operator before an operation for removing the larynx, or storage means for storing sound source data for singing a song may be provided in the controller 4 detachably.
