A grooming appliance (100) comprising: a grooming mechanism (102) for grooming a user; a motor (104) arranged to operate the grooming mechanism; and a controller (106) configured to modulate a data signal into sound produced by the grooming appliance during the operation of the grooming mechanism by the motor, in order to transmit information relating to the grooming appliance. In embodiments, the sound being modulated is caused by the motor when operating the grooming mechanism. In this case the controller is arranged to supply a drive signal to the motor in order to control the motor, and to perform the modulation by varying the drive signal in order to modulate the data signal into the sound caused by the motor during operation of the grooming mechanism. |
