As a result, the motor coils 14 interact with the counterweight base 13 to generate lateral linear displacement which causes the electronic device 1 to generate vibration, and the two elastic modules 21 serves as the buffer structure for the displacement.

Please refer to FIG. 7 and FIG. 8 together. In this embodiment, the structure of the upper part of the electronic device 1 is a speaker structure. The electronic device 1 further includes the conductive component 20 disposed on the bracket module 17, and the voice coil 19 is connected to the conductive component 20, and wherein, the conductive component 20 exposed on the outer surface of the bracket module 17, is connected to the external power source. The electronic device 1 is electrically connected to the voice coil 19 through the external power source, and the voice coil 19 generates the attracting interaction and the repelling interaction by changing the magnetic field relative to the magnetic field of the surrounding second magnetic module 16. The supporting plate 15, located beneath the structure composed of the major magnetic component 161 and the plurality of minor magnetic components 162, may serve as the role which helps the magnetic lines below the supporting plate 15 to be concentrated. Additionally, the major conductive component 24 on the major magnetic component 161 and the plurality of minor conductive components 172 inside the supporting module 17 on the plurality of minor magnetic components 162 may serve as the role which helps the magnetic lines thereon to be concentrated. In this way, through the supporting plate 15, major conductive component 24, and the plurality of minor conductive components 172, the magnetic lines of the second magnetic module 16 maybe concentrated, thereby generating better vibrational effects by the voice coil 19 under the influence of the magnetic field.

In this embodiment, the voice coil 19 changes the magnetic field through electrical means and generates the attracting interaction and the repelling interaction on the magnetic field of the surrounding second magnetic module 16. Consequently, the voice coil 19 interacts with the vibration module 18, so that the sound generated by the upward vibration and the downward vibration of the vibration module 18 is transmitted to the first sound chamber 1111 and the second sound chamber 1112. After the sound undergoes resonance within the first audio cavity 1111 and the second audio cavity 1112, the sound is made through the audio outlet 175.

Please refer to FIG. 9, which is a 3D view of the external speaker of the electronic device in this application. As shown in the figure, in this embodiment, the electronic device 1 further includes an external speaker 28 disposed on one side of the housing 11. The housing 11 has a sound hole 113 disposed at the position of the housing relative to the external speaker 28. The sound hole 113 is connected to the interior of the first audio cavity 1111 and the external speaker 28, and thus, the tone of the sound within the first audio cavity 1111 and the second audio cavity 1112 is balanced and saturated.

In summary, the present application provides an electronic device that employs the structural design where the voice coil and the motor coil share the second magnetic module to effectively reduce the needed inner space of the electronic device occupied by the combination of the speaker structure and motor structure, thereby increasing the available space of the other components. The available space may be used to enhance the design of the structures of the other components to improve the efficiency of the electronic device. Alternatively, the available space may directly reduce the overall volume of the electronic device, and it is more convenient for storage.
