磁路11具有相平行的第一端部112和第二端部111，所述第一端部112具有以该端部的中心为圆心的圆环形的狭缝113。The magnetic circuit 11 has a first end 112 and a second end 111 that are parallel, and the first end 112 has a circular slit 113 with the center of the end as the center.
线圈22通过线圈支架21支撑在所述狭缝113内。The coil 22 is supported in the slit 113 by the coil support 21.
弹拨12整体呈环形结构，弹拨12设置在磁路11的所述第二端部111，弹拨12一方面与磁路11联结，弹拨12另一方面通过高度定位圈13与线圈支架21联结，将所述线圈22与所述狭缝113对正，以便所述线圈22能够沿其轴线在所述狭缝113中震动，不会与狭缝113的壁部发生干涉。The pluck 12 has a ring-shaped structure as a whole, and the pluck 12 is arranged at the second end 111 of the magnetic circuit 11. The pluck 12 is connected to the magnetic circuit 11 on the one hand, and the pluck 12 is connected to the coil support 21 through the height positioning ring 13 on the other hand. The coil 22 is aligned with the slit 113 so that the coil 22 can vibrate in the slit 113 along its axis without interfering with the wall of the slit 113.
可以看出，本发明创造将弹拨12设置在磁路11的所述第二端部111，弹拨12不再占据发声板和磁路11之间的间隙，这样，线圈支架21的高度得以减小，从而使得发声震动驱动器4的厚度得以减小。可以将发声震动驱动器的厚度降至原有厚度的1/2-2/3。It can be seen that the present invention creates the pluck 12 at the second end 111 of the magnetic circuit 11. The pluck 12 no longer occupies the gap between the sounding plate and the magnetic circuit 11. In this way, the height of the coil support 21 can be reduced. Therefore, the thickness of the audible vibration driver 4 can be reduced. The thickness of the acoustic vibration driver can be reduced to 1/2-2/3 of the original thickness.
线圈支架21的高度小于3mm，优选2mm左右。The height of the coil holder 21 is less than 3 mm, preferably about 2 mm.
当线圈支架21的高度在2mm以下时很难在其上绕线形成线圈，量产更加困难。并且现有线圈支架都是普通的铝箔管，不能很安全地固定在发声板上。鉴于此，进一步对线圈支架21的结构做了改进，具体结构如图5。When the height of the coil holder 21 is less than 2 mm, it is difficult to wind the coil to form a coil, and mass production is more difficult. In addition, the existing coil supports are ordinary aluminum foil tubes, which cannot be securely fixed on the sound board. In view of this, the structure of the coil support 21 is further improved, and the specific structure is shown in FIG. 5.
请参照图5，线圈支架21包括筒形部212，筒形部212具有用于安装所述线圈的第三端部214、以及用于粘结发声板的第四端部211。线圈支架21还包括从所述第四端部211向第四端部211的中心延伸形成的折板部213。5, the coil support 21 includes a cylindrical portion 212, the cylindrical portion 212 has a third end 214 for mounting the coil, and a fourth end 211 for bonding the sound board. The coil support 21 further includes a folded plate portion 213 extending from the fourth end portion 211 to the center of the fourth end portion 211.
可以看出，改进之处是在原有筒形支架的基础上，增加了上述折板部213。通过增加上述折板部213，一方面，增加了线圈支架21的刚性，从而使得在线圈支架21上绕线变得容易，可以实现量产，另一方面，大大增大了线圈支架21与发声板的结合面积，因而能够更加容易地将线圈支架21牢固地粘结在发声板上。It can be seen that the improvement is the addition of the above-mentioned folded plate part 213 on the basis of the original cylindrical bracket. By adding the above-mentioned folded plate portion 213, on the one hand, the rigidity of the coil holder 21 is increased, so that it is easy to wind the coil holder 21 and mass production can be realized. On the other hand, the coil holder 21 and the sound generation are greatly enlarged. The bonding area of the board makes it easier to firmly bond the coil holder 21 to the sounding board.
