xMEMS introduces the first "Amplifier-less" MEMS tweeter

xMEMS has been making major strides in the MEMS (Microelectromechanical systems) speakers space, and it continues to push boundaries with its technology. Its speakers are used across several types of devices, from earbuds to headphones. Well, xMEMS just announced the new Lassen speakers, the world’s first amplifier-less MEMS speakers.

The thing about xMEMS’ speakers is that they’re much smaller than traditional speakers. They require much less space to produce sound, and they require a fraction of the energy. This makes them perfect for devices like smartwatches and smart glasses. This is why there’s a bright future for speakers like these, as technology is getting smaller as each day goes by.

xMEMS unveiled the new Lassen MEMS speaker

MEMS speakers are extremely small, which is great for saving space, but it does come at a cost. The smaller size makes it harder to hear them. As such, xMEMS’ previous speakers (Cowell and Muir) required an external piezo amplifier chip. However, the company has been working on a solution to that.

No help needed

That solution came in the form of the xMEMS Lassen. This speaker can drive up to 155dB SPL in the 6kHz to 20kHz range from a standard 1Vrms audio output. What makes this impressive is the fact that it can do this without the need for an amplifier. So, the company was able to fit big power into a small package. And we mean small! The Lassen driver only measures 3.2 x 5 x 1.15 mm.

Without the need for additional amplification hardware, this driver can be fit into even more devices. This driver and others like it can really revolutionize the industry.

Less is more!

The beauty of speakers as small as these is that they consume less energy. This means that devices like earbuds will be able to last longer on a single charge. Well, the xMEMS Lassen only consumes “mere microwatts of power,” which means that they’re power-efficient enough. However, what makes it better is the fact that they don’t require an amplifier. That’s one less device to power.

Additionally, since Lassne doesn’t require an amplifier, it’s cheaper to integrate it into devices. This should, hopefully, stave off price hikes for the consumers using the products.

If that’s not good enough news, ditching the amplifier means the Lassen speaker takes up even less space than past xMEMS speakers. So, companies are able to shrink their devices down even more. It’s a win-win-win, and a major step forward for solid-state MEMS technology.

Samples are currently available to try out now, and mass production will kick off in September this year.
