In this way, the third magnetic conductive sheet 2224 is matched with the fourth magnetic conductive sheet 2225, which is favorable for improving the magnetic conduction effect of the second stator 205 and improving the driving efficiency of the first driver 2212 and/or the second driver 2222.
On the basis of any of the above embodiments of the third stator 207, as shown in fig. 2, in some embodiments, the second sound generating device 222 further includes a fifth magnetic conductive sheet 2226 and a sixth magnetic conductive sheet 2227, where the fifth magnetic conductive sheet 2226 is disposed on one end surface of the third stator 207, and the sixth magnetic conductive sheet 2227 is disposed on the other end surface of the third stator 207. In this way, the fifth magnetic conductive sheet 2226 is matched with the sixth magnetic conductive sheet 2227, which is favorable for improving the magnetic conduction effect of the third stator 207 and improving the driving efficiency of the second driver 2222.
It should be noted that the specific implementation manner of the first stator 203, the second stator 205, and the third stator 207 may be various, including but not limited to magnetic elements such as magnets, electromagnets, and the like.
As shown in fig. 2, in an example, the first sound emitting device 221 further includes a first magnetic conductive sheet 2214 and a second magnetic conductive sheet 2215, where the first magnetic conductive sheet 2214 is disposed on one end surface of the first stator 203, and the second magnetic conductive sheet 2215 is disposed on the other end surface of the first stator 203.

The second sound generating device 222 further includes a fifth magnetic conductive sheet 2226 and a sixth magnetic conductive sheet 2227, where the fifth magnetic conductive sheet 2226 is disposed on one end surface of the third stator 207, and the sixth magnetic conductive sheet 2227 is disposed on the other end surface of the third stator 207. In this way, the magnetic conductive sheets can improve the magnetic conduction effect of the first stator 203, the second stator 205 and the third stator 207, and facilitate the formation of the circulating magnetic fields between the first voice coil 204 and the second voice coil 206, so as to improve the driving efficiency of the first driver 2212 and the second driver 2222, and improve the sounding quality of the sounding assembly 220.
As shown in fig. 2, in an example, the second magnetic conductive sheet 2215, the fourth magnetic conductive sheet 2225, and the sixth magnetic conductive sheet 2227 are integrally formed with the support 223 to form a magnetic conductive plate.

And the second voice coil 206 is located in a second magnetic circuit system formed by the second stator 205, the third stator 207 and the magnetic conductive plate, and is energized to the second voice coil 206, and the second voice coil 206 drives the second vibrating member 2221 to vibrate and sound according to the left-hand theorem that the energized conductive wire receives the force in the magnetic field. The first voice coil 204 and the second voice coil 206 are independently controlled, one for bass and one for treble, so that the sounding component 220 has a high-bass sounding function.
In other embodiments, the second magnetic sheet 2215 is sandwiched between the first stator 203 and the supporting member 223, the fourth magnetic sheet 2225 is sandwiched between the second stator 205 and the supporting member 223, and the sixth magnetic sheet 2227 is sandwiched between the third stator 207 and the supporting member 223. In this way, the performance of the magnetic conductive sheet is flexibly selected according to the actual requirement, and the design of the sounding component 220 is more flexible, which is beneficial to improving the sounding quality of the first sounding device 221 and the second sounding device 222.
It should be noted that the specific materials of the first magnetic conductive sheet 2214, the second magnetic conductive sheet 2215, and the third magnetic conductive sheet 2224 may be implemented in the conventional technology, including but not limited to silicon steel sheets.
