How Soundlocket® works

Soundlocket® functions just as a traditional mechanical wristwatch:

1) The sound memory is recorded and listened to by winding the locket’s knob, which launches a clockwork mechanism inside the locket and charges the device’s internal energy storage.

2) Your voice is heard by winding the knob and bringing the medallion next to the ear. You can listen to the audio as often as you want.

3) The same mechanics also allow you to change the sound memory by recording over it at any time.

4) When you are completely happy with your message, you can seal the message for good. This means that you can neither delete it nor record a new message anymore and your message stays safe for the generations to come.

Designed in Finland

Soundlockets® are primarily made of stainless steel and sapphire glass. In some cases, precious metals can also be used in the manufacturing process. Stainless steel and other metal parts are machined into components, and each component is finished using a method selected individually. The mechanical part of the Soundlocket® is assembled by hand, and the electronic components are then connected to the mechanical part. All Soundlockets® undergo a thorough quality check before being sent to their final destination.

Works like a clockwork

Soundlocket® functions just as a traditional mechanical wristwatch – the sound memory is recorded and listened to by winding the locket’s knob, which launches a clockwork mechanism inside the locket.

Mechanical heart

The core of our Soundlocket® is mechanical energy solution. Thanks to this inbuilt micro-sized energy storage, Soundlocket® can function without the need for batteries or any other external energy source. This means Soundlocket® is fully self-powered and therefore a reliable device that’s meant to last for decades, from one generation to the next.
