Automotive Mems Speaker

Here is how USound's MEMS technology enables car manufacturers to create advanced audio systems that follow the latest trends in the automotive industry. The trend of personalized automotive audio The trend of personalized automotive audio experience refers to the increasing demand for high-quality and customizable car audio systems.

AAC is a world-leading MEMS microphone supplier that delivers high-performance and cost-effective products with reliable quality and supply. We have mastered cutting-edge acoustic technologies, developed MEMS in-house, and acquired rich experience in mass production, underpinned by strategic collaboration with core suppliers.

USound 's MEMS speakers for automotive use are revoltionary. Surround stereo listening is limited to a sweet spot, symmetrically to the speaker set-up. Due to cars' current audio system design, passengers are outside of this area, either too close to the left speaker or too close to the right speaker, limiting the possibilities for spatially arranging the speakers in cars. With the ultra

Recently, MEMS speakers have been increasingly used for in-car surround sound systems. MEMS speakers, which are used in wearable wireless earphones and other products, have the advantage of being ultra-compact, ultra-lightweight, and energy efficient.

As discussed in SAR's study on MEMS speakers, automotive is one of the largest markets for speakers, with almost billion speakers used per year. SAR is expecting MEMS speakers to start being used in automotive applications from 2023, in small volumes as OEMs trial their usage. MEMS speakers could enable OEM designers to try new ways to deliver sound to passengers, through small arrays

This makes the MEMS speaker a compelling technology for true-wireless earbuds. The combination of low power consumption, small form factor and the widest possible bandwidth provides unprecedented advantages for true wireless manufacturers and end-users.

MEMS speaker pioneer USound GmbH Graz, Austria has announced its entry into the automotive market with the offer of MEMS speaker arrays. The use of arrays of speakers allows directionality of sound in the automotive cabin can be used to produce multiple sweet spots for listening. MEMS units within an array easily integrated into automotive cabin.

For MEMS speakers, the SOPRANO PRO made its market debut, featuring a smaller size and improved performance compared to the previous models. The VACC product also made its debut, known for its low noise and high integration, making it suitable for TWS and automotive road noise cancellation systems.

The MEMS speaker, due to the own intrinsic high impedance, demands a lower driving current. Table 1 shows the driving current of the MEMS speaker measured in an IEC coupler at 94 dB SPL using three different methods. Also included is the current consumption of a reference balanced armature Knowles 26824 and electrodynamic speakers Samsung
