MEMS Speakers for Ultrasonic Applications
USound MEMS speakers are the ideal audio solution for ultrasonic applications, such as wideband ultrasonic distance sensing. Ultrasound, the use of high-energy sound waves, has been utilized for measuring distance. Contrary to popular belief, ultrasound is not exclusively used for monitoring a fetus’ development in the womb. From domestic appliances and lifestyle gadgets to medical and industrial devices, ultrasonic distance sensing helps with range finding, user detection, obstacle avoidance, and many more functions that enable numerous products to operate properly.
Consumer electronics companies are always on the lookout for new components that can be used in ultrasonic applications. Due to their unparalleled audio performance at the most compact size on the market, USound speakers are the optimal ultrasonic component. Our MEMS technology can optimize the development and production of numerous devices, including common home appliances, popular lifestyle gadgets, industrial applications, and emerging entertainment devices.
MEMS Speaker Applications
Due to their small size and excellent audio performance, USound microspeakers can be used for:
True Wireless Systems (TWS) earphones
Augmented Reality & Virtual Reality Glasses and Headsets
Ultrasound
Magnetic Resonance Imaging (MRI) Headphones and Medical Devices
MEMS Speakers for Ultrasonic Sensing
Ultrasonic sensors are non-contact sensors that use wave signal travel to calculate the distance between the point of wave origin and an object. MEMS speakers can be used as ultrasonic components for measuring distance.
USound’s Conamara microspeakers in particular, achieve wideband flatness and optimal efficiency in the ultrasonic frequency range (above 20 kHz), making them the ideal solution for a wide range of applications.
USound MEMS Speaker Benefits for Ultrasonic Applications
USound speakers are approximately 20 times smaller than the average ultrasonic component. Due to their small form, they can be seamlessly integrated into miniaturized devices, reducing the device’s weight while freeing up space for additional components. At the same time, USound MEMS speakers provide excellent acoustic performance, achieving wideband flatness in the ultrasound frequency range, with the ability to select the desired operational frequency without SPL loss. Additionally, the wideband flatness enables our customers to modulate the signal and make it unique for a more robust system.
Our MEMS speaker advantages for ultrasonic distance sensing include:
- Ultra-compact and lightweight form factor for seamless integration into miniaturized devices.
- Operational frequency range up to 80 kHz.
- Sound Pressure Level (SPL) flatness in the ultrasound frequency range.
- SMT reflow soldering for an automatic pick and place assembly.
- Extended battery life for uninterrupted use.
- IPX8 rating for the most robust devices.
- Drop-proof design with 100% survival rate at a 1.9 m drop test.
- Low heat generation and decreased vibrations.
- No magnetic field.
