Description
Miniature pressure speaker that converts any flat surface into a sound source. Does not need air for raising the voice. It can be applied directly to the head and not heard by anyone else. Power is 1 W, and the dimensions are 21.5 x 14 mm.
How does it work?
Speaker has a small metal rod wrapped in a coil. When the current flows through the coil, the magnetic field causes a piece of metal to expand and contract. If applied to a flat surface, it turns into a speaker. When places at the jaw or ear bone, it turns the skull into a speaker with great sound quality. Like that the sound is coming from inside the head, nobody else can hear it.
When applying the device to your knees and bringing a finger to your ear, the shoulder becomes a conductor of sound. You can also attach it to the wall or table to get a flat speaker.
When placing directly on the skin, we recommend using an insulator, for example,Sugru, to prevent short circuit or electric shock.
