The two motor coils 13 generate opposite attraction and repulsion actions on the surrounding magnetic pieces 11 and the magnetic fields of the first main magnetic piece 151 and the second magnetic piece 16 of the first magnetic assembly 15, so that the motor coils 13 act on the fixing seat 12 to generate left-right lateral linear displacement, and the electronic device 1 generates a vibration state, wherein the lower inner sides of the two motor coils 13 correspond to the second magnetic pole S of the magnetic piece 11, the upper outer sides of the two motor coils 13 correspond to the first magnetic pole S of the first main magnetic piece 151, the upper inner sides of the two motor coils 13 correspond to the first magnetic pole N of the second main magnetic piece 161, the first magnetic pole N and the second magnetic pole S of the two second auxiliary magnetic pieces 162 are transversely arranged, the first magnetic pole N of the two second auxiliary magnetic pieces 162 respectively faces the inner sides and corresponds to the second main magnetic piece 161, and the second magnetic pole N of the two second auxiliary magnetic pieces 162 respectively faces the outer sides and corresponds to the first main magnetic piece 151. The first magnetic component 15 and the second magnetic component 16 of the present embodiment increase the magnetic field strength through the above arrangement, and further, the first main magnetic element 151 and the second magnetic component 16 of the first magnetic component 15 further assist the magnetic field line concentration of the magnetic field through the main magnetic conductive element 22, which is helpful for enhancing the actions on the two motor coils 13. The two elastic components 21 serve as a buffer structure for vibration of the fixed seat 12 driven by the two motor coils 13.
As mentioned above, the electronic device 1 also introduces power to the voice coil 19 through the second electrical portion 243 of the electrical component 24 to change the magnetic field of the voice coil 19. The voice coil 19 has opposite attraction and repulsion effects on the magnetic fields of the first main magnetic element 151 and the first auxiliary magnetic element 152 of the surrounding first magnetic element 15, so that the voice coil 19 is linked to act on the vibration element 18 to generate vertical linear displacement, so that the sound membrane element 181 and the middle paste 182 of the vibration element 18 generate vibration states, the vibration element 18 generates resonance in the accommodating groove 101, the vibration element 18 further generates sound, and the sound is generated through the sound outlet 1711 on the bracket element 171 of the bracket element 17.
In summary, the present application provides an electronic device, which uses the structural design of the first magnetic component and the second magnetic component shared by the voice coil and the motor coil to effectively reduce the internal space of the electronic device occupied by the combination of the speaker structure and the motor structure, thereby increasing the available space of other components, which can be used to improve the design of the structures of other components, 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. The second magnetic component is combined in the first magnetic component, so that the first magnetic component and the second magnetic component can improve the magnetic field intensity acting on the motor coil and the voice coil, and the motor coil and the voice coil can achieve better effects.
