Background technique

As a device for generating sound by current, a moving coil speaker has a diaphragm driven by a coil, and the diaphragm is driven by the coil to generate a controllable vibration, thereby causing vibration of the air and realizing sound playback. The existing speaker requires the diaphragm to work stably and consistently at a frequency of 20 Hz to 20,000 Hz, but the existing diaphragm is limited by materials, and the diaphragm with high rigidity causes the thickness of the diaphragm to increase and the quality of the diaphragm to increase. Although the rigidity of the diaphragm is improved after the rigidity is increased, the sensitivity is lowered, and the sensitivity of the diaphragm with low sensitivity is low, so that the diaphragm has a high treble effect. In order to achieve both the sensitivity of the diaphragm and the high-frequency characteristics, the diaphragm is required to be light in weight and high in rigidity. In the prior art, a diaphragm is formed by cutting a special dry wood, so that the treble effect of the diaphragm is improved, but the sensitivity of the diaphragm is lowered due to an increase in the total mass of the diaphragm.
