Double-sided speaker

A double-sided speaker, comprising:

• a magnetic conductive carrying board component comprising a first magnetic conductive carrying board and a second magnetic conductive carrying board, the first magnetic conductive carrying board comprising two first sidewalls and a first bottom plate, the two first sidewalls being disposed at two sides of the first bottom plate, the second magnetic conductive carrying board comprising two second sidewalls and a second bottom plate, the two second sidewalls being disposed at two sides of the second bottom plate;
• wherein, the first bottom plate and the second bottom plate form a plane, the two first sidewalls extend toward two sides above the second bottom plate, the two first sidewalls and the first bottom plate form a U-shaped configuration, the two first sidewalls are disposed at two sides above the second bottom plate, the two second sidewalls extend toward two sides below the first bottom plate, the two second sidewalls and the second bottom plate form a U-shaped configuration and the two second sidewalls are disposed at two sides below the first bottom plate;
• a first magnetic circuit module disposed at one side of the magnetic conductive carrying board component;
• a second magnetic circuit module disposed at the other side of the magnetic conductive carrying board component;
• a first voice coil disposed between the first magnetic circuit module and the two first sidewalls;
• a second voice coil disposed between the second magnetic circuit module and the two second sidewalls;
• a first vibrating component disposed at one side of the magnetic conductive carrying board component, the first vibrating component comprising a first accommodating space in which the first magnetic circuit module and the first voice coil are disposed;
• and
• a second vibrating component disposed at the other side of the magnetic conductive carrying board component, the second vibrating component comprising a first accommodating space in which the second magnetic circuit module and the second voice coil are disposed.
