2024: A Year of Innovation at PUI Audio

At PUI Audio, 2024 has been a landmark year for cutting-edge advancements in audio components and haptic technologies. This year, we’ve expanded our portfolio with groundbreaking products that cater to diverse industries including medical, industrial, consumer electronics, and security systems. Let’s dive into the key innovations that defined our journey this year.

1. Flexible Piezoelectric Haptics

One of the year’s most notable innovations is our flexible piezoelectric haptic actuator. Offering unparalleled tactile feedback, these actuators combine a broad frequency range with an ultra-thin design. Unlike traditional electromagnetic haptic solutions, these devices provide localized sensations without disturbing the entire device. Applications span handheld electronics to textile-integrated interfaces, delivering precise and immersive feedback. Additionally, the actuators are RoHS and REACH compliant for safe integration across industries​.

2. IEC 60601-1-8 Medical Buzzers

In response to the stringent IEC 60601-1-8 standards, we introduced our Medical Audio Indicators. Designed to produce standardized alarm tones for healthcare environments, these devices simplify compliance while delivering robust performance. Each indicator supports three priority levels—low, medium, and high—and is easy to control with simple DC voltage inputs. This innovation supports medical applications such as oxygenation alarms, cardiovascular alerts, and ventilation monitoring​.

3. MEMS Pressure Sensors

This year, we unveiled our PSD0401120 MEMS pressure sensor, a compact and reliable solution for measuring atmospheric pressure. With features like I2C digital output, high-resolution temperature sensing, and waterproof packaging, these sensors are ideal for applications ranging from security systems to industrial automation. The robust design enables seamless integration into systems that demand accuracy and reliability in challenging environments​.

4. Next-Generation Speakers

We expanded our speaker lineup with models ranging from 20mm to 58mm, designed for durability and performance. These new speakers offer high SPL, slim profiles, and ingress protection, making them perfect for portable and harsh-environment applications. Our speaker solutions also come with advanced Thiele-Small parameters to optimize enclosure designs and acoustic performance​.

5. Surface Mount Audio and Patented Haptics

This year saw the introduction of surface mount technologies across our audio and haptic product lines. Highlights include a 25mm waterproof speaker and a 17mm transducer designed for streamlined PCB integration. These products enhance compact device designs while maintaining superior performance under extreme temperatures​.

6. Lead-Free Buzzers

In line with environmental regulations, we developed a range of buzzers using a unique lead free material. These devices not only comply with RoHS standards but also offer improved performance and durability. Ideal for medical, automotive, and consumer applications, our lead-free buzzers eliminate the need for regulatory exemptions​.

A Commitment to Excellence

As we close the year, these innovations reaffirm PUI Audio’s mission: to deliver high-quality audio components and custom solutions that push the boundaries of technology. Whether you’re looking for haptic actuators, MEMS sensors, or audio, our team is here to help.
