Acoustic Product Design
IAR is focused exclusively on designing great sounding acoustic systems; however, after 40 years of being involved with various product designs, you tend to make a few friends. Should your team need Mechanical, Electrical, Embedded DSP, or sourcing support, IAR has a network of partners to assist. Most of these partner companies have worked with IAR for over a decade and are like us: quick-response groups of specialists with low overhead. Furthermore, these partners can operate as seamlessly as if you were working with IAR itself and together we deliver bigger solutions at incredible value.

Transducer Design
In addition to designing acoustic systems, IAR can take a catalog speaker or microphone and modify it to suit a performance target- or even design a unique transducer for your application. IAR keeps an in-house collection of ECM & MEMS Microphones, headphone drivers, receivers, microspeakers and other small transducers for prototyping / evaluation purposes and provides transducer specs that really matter (as opposed to the often incomplete or incorrect ones in the datasheet).
Receivers
Receivers (a speaker which drives the ear in the near-field), must be designed differently than a far-field speaker to accommodate for the smaller volume of driven air, and the likelihood of leaks. IAR can design both HAIR (High Acoustic Impedance Receivers) and LAIR (Low Acoustic Impedance Receivers).
|
Microspeakers
Microspeakers are challenging because there is typically minimal air back volume to work with, and to maximize diaphragm area the speakers tend to be rectangular (non axi-symmetric). IAR has integrated and designed dozens of microspeakers for laptop and tablet applications.
|
ECM Mics
ECM microphones are popular choices because of their low cost and good SNR performance. Gradient (directional) ECM Microphones provide added acoustic noise rejection and IAR has experience tailoring directional mics to meet target polar response and bandwidth requirements via careful integration.
|
MEMS Mics
While the silicon die and ASIC inside a MEMS Mic must be produced in extreme mass quantities, IAR has experience designing packaging modifications which can help meet acoustic performance targets. This could result in flatter low-frequency or high-frequency response, higher Acoustic Overload Point (AOP) or higher SNR.
