AKP's 2015 investor presentation tells us that a 15% share of the speaker market equates to 3.34B chips. You are using quite a high take up rate of 75% in most instances yet you are only arriving at 5.68B chips. By AKPs estimates, a 75% share of the speaker market would be 16.7B chips...obviously that's a huge variance between your assessment of market size and AKP's. Are you sure you aren't selling AKP short?
