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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] It is to be understood that the term “comprises”, “comprising”, or any other variants thereof, is intended to encompass a non-exclusive inclusion, such that a process, method, article, or device of a series of elements not only include those elements but also comprises other elements that are not explicitly listed, or elements that are inherent to such a process, method, article, or device. An element defined by the phrase “comprising a . . . ” does not exclude the presence of the same element in the process, method, article, or device that comprises the element.

[0061] Although the present invention has been explained in relation to its preferred embodiment, it does not intend to limit the present invention. It will be apparent to those skilled in the art having regard to this present invention that other modifications of the exemplary embodiments beyond those embodiments specifically described here may be made without departing from the spirit of the invention. Accordingly, such modifications are considered within the scope of the invention as limited solely by the appended claims.
