World’s First Monolithic MEMS Speakers Begins Serial Production

Published

on

XMEMS Labs announced the start of series production of Montara, the world’s first monolithic speaker using MEMS technology. TSMC joins xMEMS as Manufacturing Partner, and the first product to use Montara speakers will be the Chiline TR-X wireless headphones, designed by Inventec Appliances.

The headphones are due to hit the market in March 2022. The Montara speakers are said to provide “impressive spatial sonic characteristics and new levels of clarity and presence in the mid and high frequencies.”

Miniature loudspeakers currently available using MEMS technology are hybrid loudspeakers. In contrast, Montara’s micromechanical systems are both the actuator and the diaphragm. This made it possible to reduce the thickness to 1 mm and eliminate the need for calibration to compensate for the parameter spread of the actuators and diaphragms.

According to xMEMS Labs, Montara has a reproducible frequency range of 20-20,000 Hz at a SPL> 110 dB. In the range 200-20 kHz, the THD value does not exceed 0.5%. The emitter’s protection rating is IP58, which simplifies the design and manufacture of devices that are not afraid of dust and water.

Apple delays shipments of all devices: wait up to four months for a napkin for the screen

Published

Many users who buy new Apple products will have to wait several months. During this year’s holiday shopping season, shoppers are faced with the harsh reality that most of the products they order will arrive much later.

Orders for the latest products such as the Apple iPhone 13, iPad mini 6, iPad 9th generation, Apple Watch Series 7, and MacBook Pro will not be fulfilled until November or December. Even some older devices, including the iMac, Mac Pro and other more expensive MacBook Airs released in April, have also been heavily delayed in shipping.

A supply shortage from chipmakers such as Broadcom and Texas Instruments has reportedly forced Apple to cut production of the 2021 iPhone 13 by as much as 10 million units.

A disturbing sign is that it is difficult to buy even old products. Apple’s official China website reveals that the iPhone 13 will not ship until mid-November, while the iPhone 12 will be available between the end of this month and early next month. Retailers said that many specialty stores in the United States do not have such mobile phones either. The new MacBook Pro will be available mid to late November, depending on configuration.

As for the Apple screen napkin, which has already made a lot of noise, its delivery in some cases will take up to four months.

Adata overclocked DDR5 RAM to 8118 MT / s

Adata proudly shared the result of overclocking DDR5 memory: the company’s specialists managed to achieve a speed of 8118 MT / s. No technical specifications for the experiment were announced, but there is no doubt that the Intel Alder Lake platform was used – this is the first custom system with support for DDR5. There is no doubt that the overclocking used a motherboard based on the Intel Z690 chipset.

Adata claims to have achieved 8118 MT / s as the first RAM manufacturer. But it is possible that after the official premiere of Alder Lake next week, other DDR5 memory manufacturers will mark similar records.

It should be noted that back in August, Adata promised DDR5 memory with a speed of 8400 MT / s, but then a reservation was made that it would not be included in the number of modules of the first wave. That is, faster DDR5 memory will most likely appear in a year or two.

Tesla Model 3 has already won many titles and titles in the automotive world, and then another one arrived in time: LeaseLoco named the Model 3 the fastest selling electric car in the world. According to the company’s analysts, an average of 24.5 Model 3s are sold per hour worldwide. No other electric vehicle can achieve similar sales rates.

In second place is the Chinese bestseller Wuling Hongguang Mini EV – the company sells about 14.4 of these cars per hour. But at the same time, the difference in price is indicative: the Model 3 is 10 times more expensive than the Wuling Hongguang Mini EV. And it diverges almost twice as fast.
