Application of Jin Xin Electronics ADP16x DSP in Fascia Gun Products
As a hot product in recent years, the fascia gun is defined by the industry as a soft tissue rehabilitation tool. It uses high-frequency vibration to transmit force and vibration to the fascia of the human body, thereby increasing tissue blood flow and relaxing muscles, and it can make human tissues relative displacement through resonance, reduce tissue adhesions, and restore the elasticity of muscles and fascia. Compared with traditional foam rollers or fascia balls, fascia gun technology is indeed deeper and more precise for muscle and fascia relaxation.
Generally speaking, the chip and motor of the fascia gun determine the noise, hitting strength and durability of the fascia gun, and the realization of its massage function is inseparable from the core control role of the main control chip. The fascia gun chip solution of Jinxin Electronics uses ADP16x series DSP as the main control chip, which has the characteristics of high sensitivity, low power consumption, good stability and high cost performance.
The ADP16x devices offer an enhanced DSP architecture design that enables low power consumption and high-performance processing power at a low cost. Several advanced peripherals optimized for digital motor and motion control applications have been integrated to provide a true single-chip DSP controller. When compatible with existing DSP controller device code, the ADP16x provides higher processing performance and a higher level of peripheral integration.

This fascia gun scheme adopts a general version of the mini body, including the shell, massage head, transmission mechanism, and drive device. The case has a built-in 12V lithium battery pack, a voltage output range of 9V~12.6V, a total capacity of about 2500mAh, using a type-c interface, supporting 5V/2A mobile phone charger to charge it, equipped with 4 basic massage heads, the drive device uses a brushless DC motor, and the speed range is 1400~3200rpm to achieve high-frequency vibration effect. The control panel is equipped with 1 function button and 6 LED lights for interaction (4 gear lights, 2 power display and charging status indicator), and also includes modules such as power management, motor drive, signal processing feedback, etc.
In the shutdown state, press and hold the button for 2 seconds to turn on, the motor enters the first gear to run, the speed is 1400rpm, and the blue light is on;
the second button makes the motor enter the second gear operation, the speed is 2100rpm, and the two blue lights are on;
the third button makes the motor enter the 3rd gear operation, the speed is 2800rpm, and the 3 blue lights are on;
the fourth button makes the motor enter 4 gears of operation, the speed is 3200rpm, and 4 blue lights are on;
the fifth button makes the motor return to 1st gear running, the speed is 1400rpm, and 1 blue light is on;The recommended running time for each gear is no more than 10 minutes;
In working mode, press and hold the button for 3 seconds to shut down the system.
The green light is solid, indicating that the battery is ≤ 100% < 80%;
The red light and green light are on at the same time, indicating that the battery is ≤ 80% < battery;
