WelcomeBob

An intercom is a very small product with a very big job: it is the first moment someone meets a building. For WelcomeBob we designed the sound identity for that moment, delivering two ringtones and an unlock tone.

In an intercom, sound is the interface. The ringtone is how a resident knows a visitor is at the door, and it will be heard again and again, often in the middle of something else, so it has to be recognisable at once without becoming irritating. The unlock tone carries just as much weight: it is the moment the system tells you the door is open, and it needs to feel clear and reassuring. Few products rely so much on a handful of sounds.

We created a small, coherent audio identity for WelcomeBob: two ringtones and an unlock tone, designed as one family so the product sounds like itself from the first ring to the open door.

A melody that spells the name

The idea behind the melody comes straight from the name: B-O-B. The melody is written in the key of B and it ends on B as well. In musical terms, returning to the key centre is known as “going home”, the feeling of resolution when a melody lands where it belongs. For a product that sits at the front door and welcomes people in, that felt exactly right: every ring and every unlock quietly ends by coming home.

Two ringtones

The ringtones announce a visitor. Built on the B-O-B melody, they are distinctive enough to be recognised instantly, yet pleasant enough to hear many times a day.

The unlock tone

The unlock tone confirms that the door has been opened, giving the resident a clear, reassuring signal that the action worked.

The result is a compact sound identity that gives WelcomeBob a recognisable voice at the front door, from the ring that announces a visitor to the tone that opens the way in, all resolving back to B, back home.
