Important Innovative Technology

Extra Large Touchpad with Silent Switch 

In daily life, notebook computers are widely favored for their portability, with users frequently operating them in various environments such as offices, coffee shops, classrooms, and libraries. The touchpad, a standard feature of notebooks, plays a crucial role in daily usage by facilitating cursor movement and click operations, while enabling various functions through pressure application.

With users becoming increasingly familiar with touchpad operations, market demand for larger touchpads continues to grow. However, this increase in size can potentially result in more noticeable noise during pressing actions. Therefore, ultra-large touchpads featuring silent design technology not only effectively reduce pressing sounds but also deliver a better experience for users who need to use their notebooks in quiet environments. This design was implemented in two models in 2023, with plans for further expansion in 2024 to include applications to four additional models. 

Adopt efficient dynamic noise reduction for teleconferencing driven by AI technology

Acer has consistently focused on enhancing audio quality in its notebook computers. Since 2013, Acer has implemented dual-microphone array technology in its notebook computers. In 2020, in response to COVID-19, remote work and learning became the norm, with video conferencing becoming an indispensable part of modern life. We introduced noise cancellation technology based on dual-microphone arrays trained to eliminate non-vocal noise to meet the demands of video conferencing

applications. In 2024, Acer successfully implemented 22 projects utilizing innovative technology to further enhance the user audio experience. In the new notebook computer models, we have adopted a novel three-microphone design. 

The core of this innovative design lies in the introduction of a third microphone, which significantly improves AI noise reduction capabilities. This additional microphone can more precisely capture environmental noise and works in conjunction with AI noise reduction technology to effectively minimize background noise, elevating video conference audio quality to new heights. Even in noisy environments, users can clearly hear the other party's voice without repeatedly adjusting volume settings, providing

users with an enhanced audiovisual experience.

BiFrost composite cooling management system

The cooler and quieter BiFrost composite cooling management system is designed for desktop computers where special dual fan configuration allows most of the air to be exhausted and only part of the hot air remains inside. Coupled with the Vapor Chamber design, it can effectively reduce the internal temperature of the computer through its extremely high temperature uniformity and conductivity. Compared with the dual-axial fan design, the intake air temperature of the graphics card can be reduced by up to 7 degrees.

This design is combined with the 5^th generation Acer AeroBlade 3D metal fan that was only available in Acer notebooks which is 87.5% thinner than normal generic plastic fans and can increase the airflow during rotation, and with axial FrostBlade™ 2.0 technology to keep the system cool and ventilated at any time; it utilizes a static pressure design to optimize airflow while reducing vibration and noise and speeding up the cooling via a new arc-shaped design along the ends of the fins. This design is applied to the Predator BiFrost Intel^® Arc™ A770 OC graphics card launched by Acer and Intel in 2022.

Efficient anti-vibration speaker and module design

In recent years, working from home, remote meetings, and remote teaching have become the new normal due to the impact of the Covid-19 pandemic. The use of video conferencing has played a crucial role in mobile devices and notebook computers. During video conferences, users commonly use headphones (wired or wireless) and the speaker system of notebook computers as output devices.

Given the frequent and probabilistic long-term use of headphones during remote work and distance learning at home, it is crucial for us to consider how to reduce or avoid hearing damage to users in our product development and design. Mobile devices, primarily notebook computers, are key to remote work and distance learning at home. Therefore, the performance of the notebook computer speaker system is of utmost importance. However, the trend of lightweight and slim notebook computer designs significantly affects the quality and volume of the speaker system, resulting in an inability to provide good audio performance (high loudness, low distortion, faithful sound reproduction, etc.) during video calls or leisure activities, such as listening to music or playing video games. The maximum audio performance of almost all notebook computer audio characteristics will be compromised in order to address issues of resonance noise and audio distortion. 

By incorporating high-efficiency anti-vibration speakers and their modules into notebook computers, vibrations of speaker modules can be prevented from being transmitted to other components, thereby avoiding resonance noise and optimizing audio performance. 

AI Smart Charging according to user behavior

For users maintaining a regular habit of using computers for daily life and work, there will also be a certain behavioral pattern. For instance, a fixed behavioral pattern may involve shutting down and charging the computer at 11 PM,and then turning it on for use at 7 AM in the morning. Acer's battery management system will optimize the charging algorithm for different user behavior patterns, thereby delaying battery aging and increasing battery life.

The AI Smart Charging feature can be enabled on Acer notebook computers using the built-in program, Acer Sense. By learning the user's behavior through AI, different charging strategies are applied to optimize the battery life for each user. The system aims to delay the battery from reaching full charge when the power supply is available, keeping it in a low voltage storage state to slow down the aging process. The entire charging process is completed before disconnecting the power supply, ensuring that each user has access to the full 100% battery capacity. Both the learning and charging processes are fully automated and tailored to each user.

Based on the results of testing in our internal laboratory environment, enabling the AI Smart Charging setting improves battery health by over 25% after 500 charge-discharge cycles. Additionally, it reduces the battery's prolonged exposure to high charge levels within the same charging time, thereby extending the battery's lifespan.
