The Queen / We Will Rock You Tooth Tunes brush out of the package.

A sticker on the side of the Tooth Tunes brush informs the user that "For better sound and a better planet - turn off the water while you brush!"

The neck of the Tooth Tunes brush flexes backwards. When it is flexed a switch is pressed and the sound output level increases dramatically.

Looking into the end of the Tooth Tunes brush a metal piece can be seen. I suspected that this held the bottom on.

This is the metal pin which had to be removed in order to disassemble the Tooth Tunes brush.

In order to open the Tooth Tunes brush I cut down to the metal rod and then pulled it out with serrated needle nose pliars.

Three GREENCELL-branded AAA batteries as found in the Tooth Tunes brush. They don't appear to be of particularly high quality.

Looking down into the Tooth Tunes brush body past where the batteries were, two screws can be seen. These screws hold the electronics in place.

The guts of the Tooth Tunes Musical Toothbrush. Unfortunately, pulling them out tore two wires in the neck.

The neck of the Tooth Tunes toothbrush, partially cut away showing the two torn wires. Cutting was required because the parts are ultrasonically welded together.

With the head of the Tooth Tunes toothbrush partially cut open a large metal slug can be seen held in place by a rubbery sling.

Looking into the head of the Tooth Tunes toothbrush, showing the metal slug and transducer held against the brustles via a rubbery sling.

Inside the back side of the Tooth Tunes toothbrush head, behind the rubbery sling, is some slight padding.
