The project is to design an electric head massager, with an innovative full-wrap design that fits multiple key pressure points on the head. It simulates the techniques of a professional masseur, effectively relieving head tension and mental fatigue.
The core discussion of this head massager is to use "Piezo Air Pump", since it is true silent in operating. Some general parameters:
1. Resonant frequency: 21.5 KHz
2. Pressure: +40 KPa
3. Flow rate: 1.3 L/min
4. Power: 1.4 W
Effective driver is also a key point of design.
LX8201 is the first choice here, with integrated design of MCU and drive circuit. It perfectly matches the requirements of low-power and low-voltage drive of the piezoelectric air pump, and has distinct advantages in both drive performance and cost efficiency, comparing to other drive solutions.
