xMEMS Labs is bringing what it calls breakthrough technology to the wireless earbuds market late next year after a CES 2024 debut — the Cypress ultrasonic speaker. It turns ultrasonic waves we normally can’t even hear into full-frequency, hi-res audio with remarkable detail, the California-based semiconductor company said Tuesday.

The solid-state microspeaker, which will find its way into various companies’ earbuds and headphones — hello, AirPods? — generates low-frequency sound pressure for a full bass response, according to xMEMS Labs.

That makes the ultrasonic speaker a true replacement for legacy speaker technology that has only been refined, not replaced, since your great-grandparents rocked the Victrola.

If this iPhone 15 Pro rumor comes true, we’ll be seeing red [The CultCast]

This week on Cult of Mac’s podcast: The latest rumor indicates Apple just can’t kick its obsession with lackluster iPhone colors. Yes, the iPhone 15 Pro might come in “dark sienna,” aka the red that dare not speak its name.

If so, you can color us disappointed.

Also on The CultCast:

  • Apple’s longstanding dream of adding a blood glucose monitor to Apple Watch takes an important step forward.
  • New leaks and rumors give us an even better look at what iPhone 15 might bring.
  • Tim Cook reportedly hoovers up the entire output of TSMC’s next-gen 3nm chips. Power move!
  • Apple Watch faces a legal hurdle that could get it banned in the USA. (Spoiler alert: Not gonna happen.)

TSMC’s entire 3nm chip output goes to Apple

TSMC can now make 3nm processors, and Apple is all in. Literally all in — it’s reportedly buying the Taiwanese foundry’s complete output of 3nm chips.

This will be in the form of the upcoming Apple A17 and M3 processors, which are expected to both be made with the new process. It will make them faster and more energy efficient.

Apple’s chipmaker pours $3.5 billion into Arizona plant

TSMC is going large with its Arizona plant. The Taiwanese company that makes processors for almost every type of Apple device committed itself to putting $3.5 billion into its U.S. subsidiary. And that’s only part of the eventual cost.

Apple has already promised to use chips made at the plant.

As 3nm processors go into production, Apple’s chipmaker looks ahead to 2nm

Taiwan Semiconductor Manufacturing Company began cranking out chips using its new 3nm process Thursday at its Tainan plant. But, never one to rest on its laurels, TSMC is already laying the groundwork for 2nm processors.

Apple is expected to be among the first companies to benefit from the cutting-edge chips, which will be faster while requiring less power.

Production of 3nm processors finally starts at Apple’s chipmaker

3 nanometer chip production is about to begin at Taiwan Semiconductor Manufacturing Company. This is important news for Apple, as TSMC makes the CPUs for Mac, iPhone, iPad, etc.

Apple is expected to use 3nm processors in products launching in 2023, making the devices faster and more efficient.

Apple commits to buying chips from TSMC’s Arizona plant

Apple CEO Tim Cook said Tuesday that his company will buy processors made in Arizona by TSMC, which currently produces Apple’s most sophisticated chips primarily in Taiwan.

Plus, Taiwan Semiconductor Manufacturing Company revealed that it will pour even more billions into Arizona by adding a second chip factory in the state.

Apple M2 Pro chip could get performance boost from 3nm process

Apple’s upcoming M2 Pro chip will be made with an improved manufacturing process that will make it even faster and more energy-efficient, according to an unconfirmed report. Taiwan Semiconductor Manufacturing Company’s 3nm process supposedly will be used on the M2 Pro, as well as the M3.

Quite a few Macs using these chips are already in the pipeline.

Apple’s chipmaker counting on blazing-fast 2nm processors in rivalry with Intel


TSMC looks ahead to super-speedy 2nm processors
2nm processors made by TSMC will be faster while using less power than today's 5nm iPhone and Mac chips.

iPhones will continue getting smaller, faster and more efficient processors for years to come. TSMC, the company that manufactures all Apple’s chips, says it should be able produce processors in 2025 that are an amazing 2nm. These should make today’s fastest Macs and iPhones look like slugs in comparison.

Rival Intel is working hard to keep up. It says it’ll pass TSMC in a few years – but it’s missed plenty of similar self-imposed deadlines over the years.
