Abstract

The invention discloses an emergency power generation sound box, which comprises a surface shell, an aluminum cylinder and a bottom shell. The surface shell is arranged at the left end of the aluminumcylinder. The sound box is simple and reasonable in structural design, convenient and fast in usage, and high in practicality. During working, the power generation handle drives the generator to rotate to generate power. When the sound box is not in use, the electric power can be converted and stored in the battery. The sound box is environment-friendly and energy-saving, and the embarrassment that the charger cannot be used when no place is available outdoors for charging is avoided. Therefore, the device is wider in application range, and more interestingness. Under the action of the powergeneration handle base, the structure is more stable, then the device can be started and stopped through the key, the loudspeaker is controlled to work, operation is easy and convenient. Under the action of the anti-skid pad, the device is stable and resistant to skid, product information and an operation method are conveniently introduced through the sticker, and the device is small and exquisitein structure, attractive in appearance, convenient to carry and easy to popularize.
