X-axis linear motor can be said to be the "must-compete" of mobile phone manufacturers in the past two years, the motor volume increases at the same time, the performance is also constantly improving, a good linear motor at least to see these three indicators:
1, vibration intensity, due to the difference in the vibration intensity that the human body can perceive, the greater the range of vibration intensity, the more layered feelings can be experienced. This also means that the stronger the vibration of the motor, the stronger the ability to reproduce complex scenes.
2, the motor bandwidth, but also directly determine the ability to simulate: motor bandwidth. Conventional rotor motors have only one or two fixed frequencies, and Z-axis motors can only painstakingly design the vibration effects of four to five fixed frequency bands between 170Hz and 270Hz. Therefore, if you want to have a good realistic effect, you must be a broadband motor.
3, start and stop time, the start and stop time of the motor will directly affect the accuracy of the transmission of the haptic effect, if the start and stop time is too long, it will directly affect the tactile correlation, which completely loses the significance of high-quality haptic scenario. However, with the development of devices and software algorithms, the gap between this indicator has become smaller and smaller.
So today I can focus on vibration bandwidth, vibration intensity, and a concept that may not have been introduced much before: resonant frequency.
Ordinary broadband motors can only reach 100Hz-350Hz under sufficient vibration, and high-performance broadband motors can only reach 100Hz-400Hz. Today, AAC Technologies released the latest X-axis linear motor: ultra-wide frequency motor CyberEngine, which has an ultra-wide frequency band, and the effective bandwidth directly reaches 50Hz to 500Hz, and can ensure sufficient vibration in this frequency band range. After the effective bandwidth is stretched, the ultra-wideband motor CyberEngine has a broader tactile effect design space inside, which can experience the haptic range beyond all models currently on the market, and "break the wrist" with the linear motor of the iPhone.
In addition to ultra-broadband, AAC Technologies' flagship motor also has a super vibration sense, with a volume of 560mm cubic millimeters, which is no exaggeration to say that this size is the largest among Android linear motors. Of course, its vibration amount is also strongly upgraded, and the steady-state vibration amount is increased to 3 times compared with the original X-axis linear motor, reaching 1.1Grms, which is equivalent to the conventional X-axis linear motor of 1.88Grms, which can be described as xeon to large. The game scene "Bang Bang" to meat, bringing cool "fierce" tactile feedback.
Mobile phones have become an extension of our senses, and as the device that is held for the longest time every day, whether the vibration is comfortable is also crucial. The industry generally believes that the key indicator of linear motors, low frequency F0 =130Hz, may be the resonant frequency suitable for the best comfort experience of the human body. Ultra-wideband motor CyberEngine is the first X-axis linear motor in Android that can make F0 130Hz, coupled with the design effect of ultra-broadband, users can easily feel the comfortable and gentle touch of the cat, the breeze and the sand sliding over the fingertips.
5G mobile phone battery life and fever are generally doubled, and various mobile phone manufacturers have also "eight immortals across the sea, each showing their magic" in the past two years, competing in the mobile phone heat dissipation Dafa and becoming a dragon trainer. As an excellent motor, it is natural that it cannot increase the power consumption burden of the mobile phone at this critical moment. In the case of achieving the same amount of vibration, the ultra-wideband motor CyberEngine has higher conversion efficiency and reduced energy consumption compared with the original X-axis linear motor: only 0.12W, which saves more power and contributes to the battery life of the mobile phone.
Some good motors also need to match good content. For Internet content providers, there are many types and numbers of Android models, and the vibration motor models used are also different. How to ensure the consistency of cross-platform haptic effects has always been a problem that plagues content providers. Ultra-broadband motor CyberEngine supporting AAC Technology's RichTap? Haptic feedback solution has provided a number of mainstream mobile phone manufacturers and content providers with ringtone, music, games, emoticons, audio and video, advertising animation vibration design and other high-quality haptic function development and design.
For example, the recent ace racing on iQOO9 has adapted the industry's first native stereoscopic sense for the first time, accurately restoring the real haptic feedback in 20 scenes such as the collision, drift and nitrogen acceleration of the sports car, and for the first time, the mobile game racing game has a "sense of direction, drift and impact". In addition to ace racing, the national mobile game "Peace Elite" has also been connected to rich Tap? Solution, full cross-platform support for iOS and Android system high-quality vibration function, equipped with RichTap ? On the device of the program, gamers can perfectly experience the new vibration effect brought by the "vibration system" after setting the relevant parameters. More than just games, RichTap ? The solution cooperates with iFLYTEK input method to carefully design four customizable typing vibration senses of crispness, flexibility, flexibility and depth for users, linking touch, hearing and vision to bring high-quality typing experience.
Official news shows that the ultra-broadband, ultra-vibration, ultra-comfortable, ultra-power-saving ultra-broadband motor CyberEngine is not a PPT product, it will be launched on the K50 series in February, looking forward to the time to get started.
