[0002] With the improvement of living standards, people pay more and more attention to their own image, and slimming is a hot topic at present. Slimming can make people who are fat become thin and improve their own image. At present, many people use ultrasonic instruments to lose weight. The principle is that the ultrasonic emitter sends ultrasonic vibration energy with sufficient intensity to the fat layer through the human body skin, and the human body fat is effectively softened and "burns fat" while being vibrated at high frequency, so as to achieve the effect of weight loss. The ultrasonic vibration energy is emitted by the piezoelectric ceramic sheet of the ultrasonic emitter. The acting part attached to the skin surface needs a larger intensity of ultrasonic wave to achieve the purpose of weight loss. However, the piezoelectric ceramic sheet of the existing ultrasonic emitter is connected to the acting part through a piezoelectric vibrator. The energy generated by the piezoelectric ceramic sheet is lost on the piezoelectric vibrator, so the acting part cannot achieve a larger intensity of vibration, resulting in poor weight loss effect. In addition, the piezoelectric vibrator is usually connected to the center of the acting part. The vibration of the acting part near the middle position is stronger, and the vibration of other positions is weaker, so the vibration is not uniform, and the weight loss effect is not good.

The electrode piece is used to connect a power supply, emit ultrasonic waves, make the piezoelectric ceramic piece vibrate at high frequency, and the piezoelectric ceramic piece is directly connected with the face cover 6, so that the face cover 6 vibrates at high frequency and consumes less energy. After the face cover 6 is attached to the surface of human skin, the human fat can be quickly softened and "burned". In addition, the end surface of the face cover 6 vibrates uniformly, which can achieve good weight loss effect.

The second piezoelectric ceramic piece 5 is directly connected with the face cover 6.

[0031] As shown in Figure 2 , the bonding area of the second piezoelectric ceramic piece 5 and the face cover 6 determines the uniformity of the high-frequency vibration of the end surface of the face cover 6. The center of the second piezoelectric ceramic piece 5 coincides with the center of the face cover 6. The second piezoelectric ceramic piece 5 transmits ultrasonic energy to the face cover 6. The center of the face cover 6 vibrates most strongly, and gradually decreases to the surrounding. Generally, the bonding area of the second piezoelectric ceramic piece 5 and the face cover 6 is two-thirds to three-quarters of the area of the end surface of the face cover 6. In the embodiment, the bonding area of the second piezoelectric ceramic piece 5 and the face cover 6 is three-quarters of the area of the end surface of the face cover 6, which can make the vibration of the end surface of the face cover 6 as uniform as possible.
