"iPhone 5S MEMS Knowles Microphone - Reverse Costing Analysis"

report to their offering.

In this version of Apple iPhone, Knowles succeeds in integrating two MEMS microphones out of the three present in the phone. The third microphone is from AAC Technologies which was also already present inthe previous iPhone 5.

Apple thus uses the same MEMS microphones suppliers for the iPhone 5S,but each of them modified the design and the manufacturing process of their components to improve them by making them more robust. Compared to the microphone used in the iPhone 5, Knowles major changes include the number of transducers of the MEMS die (impacting directly the die size) and the thickness of the backplate.

More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be. We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smar...
Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed. This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...
