Abstract
A home appliance and home appliance system are provided which enable a portable terminal not to recognize an acoustic signal sound corresponding to product information output by the home appliance as noise. Thus, the acoustic signal corresponding to product information output by the home appliance may be transmitted to a service center through the portable terminal. The home appliance may include a controller that sets a dead time at a predetermined interval of time with respect to a signal corresponding to product information to avoid a noise detection section of a portable terminal, a converter that converts the signal into an acoustic signal of a predetermined band, and a sound output device that outputs the acoustic signal as sound.
