Executive Summary
The consumer MEMS microphone market is expected to reach $1.5B in 2024 from $1.1B in 2019, according to the “Microphones,
Microspeakers and Audio Solutions” report from Yole Développement. The main drivers are smart speakers and wireless earbuds.
Two main players are sharing the MEMS microphone market, Knowles and Goertek, with market shares of 39% and 28%,
respectively.
In this dynamic context of the consumer microphone market, System Plus Consulting provides a deep comparative review of
technology and cost of 19 MEMS microphones from the main microphone suppliers on the market: Knowles, Goertek, AAC
Technologies, STMicroelectronics, TDK-InvenSense, TDK-Epcos, Cirrus Logic, and Vesper.
System Plus Consulting analyzes the several technologies of microphones to provide an insight on their structure, technology,
processes and costs. We look at their package, ASIC and MEMS dies, dimensions, MEMS internal structure, package and MEMS
cross-sections, and substrate types, in order to determine each MEMS process.
The innovations and technology evolutions for each manufacturer are noted including the differences between the main
competitors.
The MEMS Microphones have been compared in terms of: Structure, package (type of substrate, dimensions, cross-section),
MEMS technology (size, design) and ASIC technology (size, technology node).
The MEMS Microphones have been finally compared in terms of cost: Detailed MEMS cost, ASIC cost, test and packaging costs.
This report includes an overview of the microphones used by the main smartphone suppliers in the market. Also, the supply chain
of the microphones is evaluated for each supplier.
