Dongguan Heju Precision Electronic Technology Co., Ltd., established in 2008, is a precision stamping factory located at the ferry side of peihouwei group, Renzhou village, Shatian Town, Dongguan City, Guangdong Province. Professional production and processing of precision hardware small components, VCM motor Etc.
 
 
VCM motor The abbreviation of voice coil motor, commonly known as voice coil motor or voice coil motor. The main principle is that in a permanent magnetic field, by changing the DC current of the motor coil, the current is converted into mechanical force to control the stretching position of VCM spring sheet, so as to drive the lens to move up and down to achieve the function of lens focusing, which can achieve the purpose of moving the whole lens in a small distance, changing the focal length, and achieving the purpose of clear image.
 
 
VCM motor can be divided into open loop motor, close loop motor, alternate motor, OIS optical anti shake motor, OIS + close loop six axis motor. Because the open motor is widely used and occupies most of the market share, it is generally referred to as VCM motor. In fact, the generalized VCM motor includes closed-loop motor and OIS motor. Nowadays, the OIS (optical image stabilization) technology has become a popular image stabilization technology for mobile phone, which is also called optical image stabilization. The OIS motor needs to add a gyroscope which can sense the hand shake on the basis of the original VCM motor. The gyroscope can measure the angle of camera jitter. According to the image offset caused by the gyroscope, the system controls the offset of the lens relative to the image sensor in the opposite direction, so as to eliminate the image offset.
 
 
According to the in-depth market research and investment forecast of OIS motor industry in the next few years, the market share of ordinary VCM motor (open motor) is up to 80%, and that of closed-loop motor is 6%. Although OIS is very popular, it only occupies 3% of the market, while other types of motors jointly occupy 11% of the market. In 2017, the market scale of OIS motor in China was 275 million yuan, and the main market share was occupied by Japanese enterprises.
 
 
OIS motor has developed rapidly in recent years. As early as the end of 2013, ZTE Nubia took the lead in launching the Nubian zs5, the first mobile phone equipped with OIS motor in China. Even earlier in foreign countries, Google, HTC, Nokia and other mobile phone brands tried to integrate OIS motor into mobile phones. However, it is Apple's 5.5-inch iPhone 6 launched in September 2014 that led the OIS motor to March. As the leader of mobile phone brand, apple company will pay great attention to the launch of almost every mobile phone. The new configuration of its mobile phone leads the trend in the industry just like a direction sign. But of course, it also needs that its configuration is really what consumers need and expect, so as to arouse a thousand waves at the right time.
 
 
As early as 2014, OIS anti shake technology has attracted much attention from camera motors. At that time, some VCM motor manufacturers had OIS samples. However, due to the high-end technology at that time, the terminal manufacturers did not adopt the technology, so the OIS technology was delayed for a period of time. It is very difficult for domestic high-end motor manufacturers to enter the first-line brands. Oppo, vivo and Huawei account for up to 20% of the world's VCM motors. However, most of the domestic high-end flagship models in the market are supplied by international manufacturers such as TDK, Alps and meizhimei, while the orders of OIS motors from Chinese manufacturers are very limited.
 
 
From the perspective of the market, the domestic terminal manufacturers do not have high recognition of domestic OIS motors. Due to the lack of relevant product verification, the terminal manufacturers are afraid of ordering. Secondly, from the perspective of manufacturing process, the yield is not high, which is one of the reasons why terminal manufacturers are worried. from OIS motor In terms of mass production capacity, at present, only the domestic first-line motor factories such as xinsihebulu, sanmeida and epeiyi can realize the small batch production of OIS motors. Although haoze, Zhonglan and other manufacturers, which are still in the second camp of VCM motors, are in the layout, so far, the three VCM motors mentioned above have not realized the small batch production capacity of OIS motors.
 
 
At present, the main reason why OIS anti shake is not popular is that the price and cost are too high. The only first-line manufacturers willing to pay for this are Oufei Guang, Shunyu, Qiuti and Xinli. Domestic brands can accept the price of OIS motor at about US $3, and the price of terminal brand can match OIS motor at least more than 2500 yuan. Huawei's high-end mobile phones, such as vivo and OIS, are only used in anti shake technology of domestic mobile phones and OIS. There is no doubt that the popularization of OIS anti shake technology has encountered a bottleneck due to multiple factors such as cost factors and mass production capacity. If the cost factor is controlled, small brands are willing to enter the technology field, then this popularization opportunity will be more likely to be realized.
