Background

Sonic toothbrushes are those in which the vibration frequency of the bristles or head is the same as or similar to the sonic frequency, and are therefore also called sonic vibrating toothbrushes. The non-literal understanding of brushing teeth with "sound waves" is that the bristles, which are similar to the vibration frequency of the sound waves, move rapidly, creating an ultra-strong cleaning effect nearly 100 times better than that of the traditional manual toothbrush, and becoming one of the most popular oral care products.

With the increasing national standard of living, consumers have higher and higher requirements on the sonic toothbrush, such as different requirements on frequency, current, noise, vibration force and the like, for users, the vibration force is a direct experience, and the pressure of the brush head is the most main influence factor of the vibration force.

However, in order to reduce the influence of the brush head pressure on the vibration, the conventional acoustic wave motor reduces the vibration force loss caused by the brush head pressure by increasing the magnetic force of the magnet and the magnetic field force of the coil, but this also increases the cost, power consumption and volume of the motor, and the integrated design of the internal structure of the motor becomes very important under the condition that the volume is not increased or decreased. For the acoustic wave toothbrush, a low-cost, low-power consumption and small-volume acoustic wave motor is needed to meet the personalized requirements of different consumer groups, and the acoustic wave motor is the most important development direction in the future.

Therefore, it is necessary to design a new type of stator integrated acoustic wave motor.
