In today's rapidly evolving electronic entertainment technology, the game controller serves as a crucial bridge connecting players to the virtual world, with every detail being of utmost importance. Today, I would like to introduce to you the practical application of Kaihua Electronic Components in game controllers.
- Kaihua Hall Effect Joystick
The Hall Effect joystick, with its unique Hall Effect principle, completely breaks through the limitations of traditional carbon film joysticks. It utilizes a chip and magnet induction system, where the chip detects changes in magnetic flux as the magnet moves, converting it into analog voltage output. This enables precise detection and conversion of control signals, providing players with an unprecedented gaming experience. This joystick is not only a non-contact input device but also a key factor in allowing players to pursue the ultimate gaming experience.
Kaihua has introduced four types of their new Hall Effect joystick series. These include the CJP1311D series, CJP1311A series, and CJP1675D series. All of them are self-developed products and have obtained national patent authorization.
The Kaihua 3D Hall Effect joystick, unlike other joysticks on the market that require two separate chips to control the X and Y axes, can control both axes with just one chip. This design provides a simpler structure, reduces cumulative errors, and offers higher output precision. This distinguishes it from other joysticks that use two chips, with each chip only capable of controlling a single axis (X or Y).
Kailh's laboratory team conducted comprehensive comparisons between Kaihua joysticks and popular joysticks on the market, resulting in the following intuitive data:
-
Power Consumption:
Kaihua Hall Effect joysticks have varying power consumption levels based on usage characteristics. The maximum power consumption is only 4mA (fast mode), and it can go as low as 2mA (slow mode)/2uA (sleep mode). Overall, Kaihua joysticks have lower power consumption compared to linear Hall Effect joysticks. -
Sensitivity (SEN):
Kaihua Hall Effect joysticks offer a wider adjustable sensitivity range. With VDD=3.3V, the sensitivity can be configured from 1 to 9 mV/Gs according to requirements. -
Return Accuracy:
Kaihua Hall Effect joysticks have a return accuracy controlled within ±5%, while similar products on the market have a return accuracy of ±6.3%. -
Linearity:
Linearity is controlled within ±3%. -
Voltage Divider Error:
Kaihua Hall Effect joysticks have a voltage divider error controlled between 41% and 59%. -
Swing Feel:
Kaihua Hall Effect joysticks maintain a smooth feel even at a swing angle of 60°, exhibiting a circular feel. In contrast, similar products on the market may experience a sense of stickiness and stoppage when the swing angle is between 50° and 60°. Compared to other joysticks, Kaihua joysticks have a wider range of usable angles, ensuring a smooth feel even at larger angles. -
Switch Press Feel:
The joystick provides a strong and distinct tactile feedback, with clear and crisp pressing sound. -
Low Output Noise:
With VDD=3.3V and BW=1KHZ, the maximum output noise is 10mVpp. -
Lifespan:
The joystick has a swing lifespan of 5 million cycles and a switch press lifespan of 1 million cycles.
Compared to the currently available Hall Effect joysticks on the market, Kaihua's Hall Effect joysticks offer significant improvements in performance. They are widely applicable in various products such as gaming controllers (e.g., PS4/PS5), drones, instruments, industrial equipment, automotive applications, toys, and more.
2-Kailh Carbon Film Joystick
In addition to the cutting-edge Hall Effect joysticks, Kaihua has also been heavily involved in the traditional mainstream carbon film joysticks for many years. In terms of appearance, the Kaihua carbon film joystick JP1311 shares a similar mounting dimension with the ALPS RKJXV series, making it a seamless replacement option. Moreover, it features an integrated packaging design and has been granted a national utility model patent, demonstrating Kaihua's technological innovation capabilities.
In terms of performance, Kailh's carbon film joystick demonstrates remarkable advantages.
-
Voltage Divider Error:
Controlled within the range of 43% to 57%, with a precision that surpasses similar carbon film joysticks on the market by two percentage points. -
Operating Torque:
12±4mN.m, providing better consistency in tactile feedback compared to similar products. -
Operating Angle:
Up to 27.5 degrees, offering a wider range of operational choices. -
Joystick Potentiometer Lifespan:
Minimum of 3 million cycles, exceeding similar products on the market by 50%. -
Switch Press Lifespan:
Up to 1 million cycles, doubling that of similar products on the market. -
Rotation Feel:
Smooth and seamless rotation without any stickiness, with strong joystick return, delivering a smoother and more fluid gaming experience for players.
The crucial functional components of Kailh's superior carbon film joystick, namely the brush and the carbon film, employ a surrounding beam structure.
-
The brush's claw on both sides adopts a surrounding design, ensuring stable contact force, minimal triggering frequency elasticity, balanced force distribution, and a reduced likelihood of poor contact.
-
The motion direction (circular motion) that contacts the carbon film is always in the same direction, resulting in minimal contact force and triggering frequency elasticity, reliable contact, and resistance to deformation.
-
The surrounding beam structure facilitates stable and balanced current flow from both sides, leading to improved conductivity and reduced drift occurrences.
-
The outer two claws have a smaller and narrower contact area with the carbon film (in the middle section), allowing for stable contact in the middle segment of the carbon film and ensuring smooth impedance output.
-
The carbon film's middle conducting terminal adopts a structure with copper plating, gold immersion, silver printing, and an anti-sulfurization layer. Even if the surface's anti-carbonization layer is worn off, the underlying copper plating and gold immersion layer provide exceptional wear resistance. Patent applications have been filed for this technology.
-
The carbon film does not require encapsulation. After printing, it can be assembled directly. The carbon film layer is not subjected to secondary processing such as encapsulation injection molding, resulting in a cleaner structure and highly stable electrical output, minimizing the potential for drift.
To validate the controllability of the carbon film joystick, the product undergoes multiple experiments in Kailh's laboratory. These experiments include, but are not limited to, lifespan testing, switch impedance detection, total resistance detection, noise detection, jitter detection, voltage divider and return testing, practical joystick origin drift detection, zero dead zone detection, circular error detection, humidity testing, high and low-temperature testing, salt spray testing, drop resistance testing, and environmental testing. These tests ensure that Kaihua's joystick meets the required standards before it is introduced to the market.
In conclusion, Kailh's Hall Effect joysticks offer precise control and smooth rotation, enabling players to have more delicate and responsive gameplay. Whether it's fast movements or precise aiming, these joysticks can easily handle them.
On the other hand, the carbon film joysticks provide a smooth feel and long-lasting durability, earning the favor of a wide range of players. Their outstanding performance not only enhances the overall quality of gaming controllers but also provides players with a more comfortable and seamless gaming experience, allowing them to enjoy the game to the fullest.
Furthermore, when combined with Kailh's tactile switches and micro switches, the complete package can be applied to gaming controllers, providing players with a smooth, accurate, and comfortable gaming environment. brands such as Feizhi, Beitong, and Geshi Xiaoji have already adopted Kaihua products and become partners in utilizing Kaihua's full range of controller solutions. Whether they are professional gamers or casual gaming enthusiasts, users can experience the significant improvements brought by Kaihua products, adding more fun and possibilities to their gaming experiences.
