  • Please turn off the silent mode on your mobile device for microphone detection.
  • In the case of PC, please grant permission to use the microphone.
  • Voice data is not stored on servers, etc. Privacy Statement

A changing electrical signal is fed to the loudspeaker's voice coil, which lies within a permanent magnet's magnetic field.
The coil signal causes it to behave like an electromagnet, making it push against the permanent magnet's field. The speaker cone is then pushed in and out by the coil in time with the signal.
