This user-programmable doorbell plays any melody you want when someone comes to your house and rings it.

I present this musical bell for the home, which allows the user to record the melody you want to ring when someone comes to your house and ring the bell, giving a twist with respect to common bell that only has one or more melodies established, without any option to change it to any place you want. Besides the driver standing at the door is wireless and touch sensor, facilitating installation to not need cable to connect the drive to bell.
