Mosquitone (モスキート()(おん)()()()()()()()(), Mosukīto On—lit. "Mosquito Sound") is a device used to have secret conversations between young people by emitting high-frequency sounds.[1]


The Mosquitone has an egg-shaped appearance, it has a speaker on top of the device, and there is a small rectangular button on the bottom that activates the high-frequency sound.[1]

During the third and fourth days of the Black Whale voyage to the New Continent, Prince Kacho uses Mosquitone to secretly communicate in Morse code with Melody about her escape plan.[1][2]


  • The name of the device is most likely a junction of the words "mosquito" and "tone".
