Voice Coil Motor is widely used in mobile phone industry because of its simple structure, smooth operation, small size and high speed. 

     The voice coil motor in the mobile phone industry is mainly divided into two parts: Voice Coil Motor support of automatic equipment in the mobile phone production applications are currently, voice Coil Motor in the laser cutting machine, laser marking machine, dispensing machine, packaging machine have practical applications, and these devices are indispensable to mobile phone production automation equipment. In addition, Voice Coil Motors have been heavily used in touchscreen testing of mobile phones, which mainly makes use of the voice coil motor's“Soft landing” function, because this function is very helpful for testing precision fragile or high-value parts. Voice coil motor in speed mode to control the lower force close to the surface of the object, while continuously monitoring the position error, once contact with the surface of the object, the position error increased to a pre-set value, the execution axis will remain in that position on the surface of the object. The advantage of“Soft landing” is according to the position of the object surface, contact surface; because of the error of the surface position, will overshoot and less; the time used is too long, affect the production efficiency; ensure speed, ensure accuracy. 

     Now, some mainstream phones have voice-coil motors. Apple, for example, has a voice-coil motor in its iphone 13, which went on sale this year, and voice-coil motors in some iphone 6 and Vivo phones.

      Kunshan Tong Mao Electronics Co. , Ltd. has been deeply involved in the voice coil motor field for more than 10 years. Tong Mao manufactures high-performance and high-quality Voice Coil Motors, which have been tested and experimented with by Huawei, apple, Samsung and other smart phone manufacturers, including the touch screen of mobile phones.
