In the present embodiment, the voice coil 19 changes the magnetic field by an electrical manner, and generates a relative attraction and repulsion effect to the magnetic field of the surrounding second magnetic component 16, so that the voice coil 19 acts on the vibration component 18, and the sound generated by the vibration component through up-down vibration is transferred to the first sound cavity 1111 and the second sound cavity 1112, and after the sound resonates in the first sound cavity 1111 and the second sound cavity 1112, the sound is emitted from the sound outlet 175.

Please refer to fig. 9, which is a perspective view of an externally hung speaker of the electronic device of the present application. As shown in the embodiment, the electronic device 1 further includes an external speaker 28, the external speaker 28 is disposed on one side of the housing 11, the housing 11 has a sound hole 113 corresponding to the external speaker 28, and the sound hole 113 is communicated with the first sound cavity 1111 and the inside of the external speaker 28, so that the sound colors in the first sound cavity 1111 and the second sound cavity 1112 can be balanced and saturated.

In summary, the present application provides an electronic device, which uses the structural design of the voice coil and the motor coil to share the second magnetic component, so as to effectively reduce the internal space of the electronic device occupied by the combination of the speaker structure and the motor structure, and further increase the usable space of other parts, which can be used to improve the structural design of other parts, so as to improve the performance of the electronic device. Or directly reduces the whole volume of the electronic device, and is more convenient to store.
