In the present embodiment, the battery case 30 may be, for example, a rectangular parallelepiped or a cube. The housing 31, the rectifier 37, and the charging unit 38 are all disposed within the battery case 30. Since the components of the power generation battery 3 are all disposed in the battery case 30, the battery case 30 can have different shapes to be correspondingly accommodated in different portable electronic devices. Alternatively, battery housing 30 may have the shape of a universal battery for application to portable electronic devices of the same type or similar type. Thereby, the power generation battery 3 provided by the embodiment has better convenience and versatility.

One set of solenoids 34 corresponds to the magnetic element 32 and the other set of solenoids 35 corresponds to the magnetic element 33. In other words, the axes of the two sets of solenoids 34, 35 are respectively parallel to the direction in which the corresponding magnetic elements 32, 33 are disposed (the first direction D1 or the second direction D2). Thereby, the assembly volume of the housing 31, the two sets of the solenoids 34, 35 and the two magnetic elements 32, 33 can be reduced, thereby miniaturizing the power generation battery 3 to adapt to the miniaturization of the portable electronic device. direction.

In this embodiment, preferably, the first direction D1 is perpendicular to the second direction D2. In this way, the power generation battery 3 can recover the vibration energy in a plane to the utmost extent. However, the invention is not limited thereto.
