1. A vibration device in a bone conduction speaker, comprising:
compound vibration parts connected to a magnet component, wherein
the magnet component is configured to drive a voice coil to vibrate; and
the compound vibration parts include two or more vibration parts at least partially attached to each other; and
a first vibration conductive plate configured to fix the compound vibration parts to a housing of the bone conduction speaker, wherein
the vibration of the voice coil drives the compound vibration parts or the first vibration conductive plate to generate vibrations having at least two resonance peaks, frequencies of the at least two resonance peaks being catchable with human ears, and sounds are generated by the vibrations transferred through a human bone.
