Knocking / doorbell


Knocking is an innovational doorbell that is designed to replace usual press-and-ring doorbell. It has a built-in vibration sensor that converts natural knocks on the door into pleasant ring music.
In daily life, usual doorbell are not very user-friendly. The press button is not easy to find. Furthermore, it is usually too high for children and those who are disabled and use a wheelchair. Knocking solves the problem by removing the press button. We integrate the doorbell with vibration sensor. Visitors can knock anywhere they want and then the bell will know someone is knocking and play pre-configured ringtone.
