The two smartphones in human hands use a coil motor(coil motor)! Twenty years ago today, no one could have imagined that mobile phones could be so intelligent, and no one could have imagined that China had nearly two smartphones per person, with a smartphone ownership rate of 86 %. And as the new mobile phone market cycle becomes shorter, the cycle of replacement of mobile phones also becomes shorter. Do you know how the vibrational effects of smartphones, photographic effects and so on are achieved? This applies to a device called a loop motor(loop motor).

     With the increase in the demand for mobile phones, domestic companies that produce coil Motors(coil motors) are also increasing significantly. They are mainly distributed in a few provinces and cities, with the largest distribution in Guangdong, followed by Zhejiang, Tianjin, Shanghai, and Jiangsu. South and other places, Japan and South Korea are dominated by companies, with total output accounting for 80 % of the world's total, of which the number of exports accounts for the majority.
     The ring motor(ring motor) is used to achieve the vibration function of the mobile phone. When receiving a text message or telephone, the motor starts to drive the eccentric wheel to make a high-speed rotation, thereby generating vibration.

     With the development of camera phones toward high pixels, the focus function is required. In general, users want a camera phone with higher pixels to have autofocus. However, according to the traditional method, the focusing function will greatly increase the size of the circuit board and the thickness of the mobile phone. In order to solve this problem, mobile phone coil Motors(coil motors) are used for camera phones.
     Sound coil motor(sound coil motor) is a special type of direct drive motor that can directly convert electrical energy into linear motion mechanical energy without the need for any intermediate conversion mechanism. The principle is: In the uniform air gap magnetic field, a cylindrical winding is placed, and the electromagnetic force generated by the winding power drives the load to reciprocate in a straight line. Changing the strength and polarity of the current can change the size and direction of the electromagnetic force. Therefore, the sound coil motor can move in a straight line or rotate. It has the advantages of high response, high speed, high acceleration, simple structure, small size, good force characteristics, and convenient control.

     Tongmao coil motor(sound coil motor) will make unremitting efforts to promote the development of China's industrial drive industry, and is committed to becoming a reliable sound coil motor(sound coil motor) for customers, a supplier of linear motor manufacturers, and continues to create value for customers.
