背景技术Background technique
人之所以能够听到声音，是因为空气中的振动通过外耳耳道把振动传递到了耳膜，通过耳膜形成的振动驱动人的听觉神经。The reason why people can hear the sound is because the vibration in the air transmits the vibration to the eardrum through the ear canal of the ear, and the vibration formed by the eardrum drives the human auditory nerve.
骨传导扬声器工作时，通过人的皮肤、皮下组织及骨骼传递到人的听觉神经，从而使人听到声音。人的耳朵在正常情况下，只要不是中外耳损坏或用手塞住耳道，声音通过骨骼直接传导与声音通过空气传导到耳膜中的输出功率相比要薄弱很多，故限制了骨传导扬声器的应用。When the bone conduction speaker works, it is transmitted to the human auditory nerve through the human skin, the subcutaneous tissue and the bone, so that the human hears the sound. Under normal circumstances, as long as the middle or outer ear is not damaged or the ear canal is blocked by hand, the sound is directly transmitted through the bone and the output power of the sound transmitted through the air to the eardrum is much weaker, thus limiting the bone conduction speaker. application.

The vibrating plate 3 includes holes 1 on both sides thereof, and the hole 1 can be used to perform the vibrating member and the driving member. Fixed together.
但现有技术中的这类传振片因为属于实心方形结构，其硬度较大，导致了纵向位移较小，从而限制了骨传导扬声器的冲程，制约了其输出功率；同时，装配中振动部分通过两个孔与驱动部分连接，因为是两点定位难以准确定位和固定，使得组装中容易侧翻，导致装配不良，而且装配也不方便。传振片的设计是使得骨传导扬声器灵敏度高输出功率大和装配容易的关键部分，因此，现有技术还有待于改进和发展。However, since the vibration-transmitting sheet of the prior art has a solid square structure, the hardness thereof is large, resulting in a small longitudinal displacement, thereby limiting the stroke of the bone conduction speaker and restricting its output power; meanwhile, the vibration portion in the assembly The two holes are connected to the driving portion because it is difficult to accurately position and fix the two-point positioning, which makes the assembly easy to roll over, resulting in poor assembly and inconvenient assembly. The design of the vibration transmitting sheet is a key part that makes the bone conduction speaker high in sensitivity, large in output power, and easy to assemble. Therefore, the prior art has yet to be improved and developed.
