What changed in Datavault AI Inc.'s 10-K — 2023 vs 2024

Item 1. Business ​ Overview We believe that the future of audio technology is in wireless devices and that WiSA is well positioned to deliver best-in-class immersive wireless sound technology for intelligent devices and next generation home entertainment systems. Historically we have sold modules which wirelessly transmit and receive audio directly to speakers.

The segment of the wireless audio market that WiSA focuses on is comprised of scalable multichannel solutions with levels of latency that are low enough to synchronize with video. The term multichannel refers to the use of multiple audio tracks to reconstruct a sound field using multiple speakers.

As part of the effort to grow the wireless multichannel home audio segment, WiSA Technologies, Inc. was a founding member of the WiSA Association, an association dedicated to providing industry leadership and consumer choice through interoperability testing between brands. Products certified and marked with a WiSA Association logo have been tested to inter operate.

WiSA sold custom semiconductor chips and wireless modules to premium audio brands in the consumer electronics industry. We believe that a growing adoption of our technology by leaders in this industry will revolutionize the way people experience media content through their mobile and handheld devices, televisions (“TVs”),soundbars (“SBs”), set-top-boxes/streaming devises and personal computers (“PCs”).

Our Business Focus Our primary business focus is to enable mainstream consumers and audio enthusiasts to experience high quality wireless immersive audio.

We intend to continue selling our proprietary wireless modules to consumer electronics companies while also expanding our focus to implement a lower-cost solution by porting our software onto commercially available internet of things (“IoT”) modules with integrated Wi-Fi technology.

Industry Background The primary growth segments for in-home entertainment have been “Bluetooth” stereo accessories which include single speakers, headsets, and more recently, “multi-room” stereo speakers that use your home’s Wi-Fi network to stream audio throughout house. Another market that continues to grow is the sound bar market.

Sound bars are typically sold with wireless subwoofers and may also be sold with wireless rear speakers. Our Technology Our fundamental technology addresses some of the main issues that we perceive hinder the growth of immersive audio in the home: complexity of setup, cost, interoperability between smart devices and the speakers, and robust wireless performance.

We believe that consumers want to experience theater-quality immersive sound from the comfort of their homes. However, traditional immersive audio systems, commonly referred to as home theater surround sound systems, are wired and often require expensive audio-visual (“AV”) receivers to decode the audio stream, leaving the consumer with the burden of concealing the wires.

Hiring a professional to hide the wires into the walls or floor is invasive, complicated, costly, and time consuming. Our first-generation wireless technology addresses these problems by transmitting wireless audio to each speaker at Blu-ray quality (uncompressed 24 bit audio up to 96 kHz sample rates) and emphasizing ease of setup.

Our next generation technology, WiSA E, is software IP designed for (i) easy implementation for the manufacturing brand to design with, (ii) broad flexibility to accommodate various price points and business models, and (iii) maintaining high quality wireless performance for the consumer. 2 Table of Contents Having successfully developed wireless audio solutions for the high-end of the immersive audio market, WiSA is continuing its development of proprietary software (WiSA E) targeted at bringing its best-of-class immersive audio technology to entry/mid-level audio systems.

Noting the growth of the sound bar market, WiSA plans a low-cost, entry-level wireless audio solution designed to meet the needs of the consumer looking for a sound bar-based, value-driven immersive audio system.

To address this market segment, WiSA is currently developing certain proprietary software for which patent applications have been submitted that will enable sound bars as well as smart devices that have Wi-Fi and video media to deliver immersive audio. First development kits for WiSA E began to ship during late Q3 2023 (pursuant to confidentiality agreements).

Our goal is to commercialize a software based -solution, which other brands can integrate into their devices, that will (i) reduce integration costs for mass market use, (ii) utilize Wi-Fi for wireless connectivity, making it easy to integrate into today’s high volume, low cost systems on a chip (“SOC”) and modules, (iii) provide a low power consumption option to allow for use in battery-powered devices, and (iv) provide compatibility with popular consumer electronic operating systems.

WiSA Association Our wholly-owned subsidiary, WiSA, LLC, operates the WiSA Association, which is an association of brands, manufacturers, and influencers within the consumer electronics industry, with the purpose of promoting a standardized method of interoperability between wireless audio components using WiSA’s technology.

The WiSA Association creates, maintains and manages specifications for wireless interoperability that are available to all WiSA Association members. For products with a WiSA Association certification, the WiSA Association also creates, maintains, and manages testing criteria and specifications for all products to be listed, marketed and sold.

WiSA-certification is an industry-wide “stamp of approval” certifying that a product is interoperable with other products in the WiSA ecosystem and has passed several high-performance tests ensuring interoperability and wireless performance standards are met. As the sole owner of WiSA, LLC, we certify all WiSA Association products.

WiSA, LLC is also the IP licensing organization for WiSA E interoperable transmission from smart devices to audio devices. In Q4, 2023, WiSA, LLC announced a licensing program for display devices (TVs and projectors). In the first 90 days three manufacturers have signed licenses.

Currently, WiSA-certified products are required to use WiSA modules in order to meet the standards set by the WiSA Association. As a result, WiSA Association members purchase modules from us in order to build their products to meet such standards.

Among WiSA-certified products, consumers will be able to outfit their home entertainment system with WiSA-certified speakers and components from any participating vendor with the assurance that the devices will interoperate and provide high quality wireless HD surround sound.

The WiSA Association manages logo usage and trademark guidelines, investigates alternative markets, connects brands to manufacturing resources, and, we believe, provides industry leadership in solving the challenges facing the home theater and commercial markets in the integration of wireless audio technology.

Modules WiSA has designed wireless modules that provide high performance wireless audio for our customers to integrate into their products, such as a speakers, TVs, soundbars, set-top-boxes, and HDMI dongles.

These modules can be designed using our custom semiconductors with our IP built in, as well as a Wi-Fi radio for communications or with our WiSA E software loaded onto a third party IoT Wi-Fi chip.

By designing and selling these modules, we believe that we can reduce our customers’ design expense, accelerate their time-to-market cycle, and reduce the cost of each module. The consumer’s smart devises must have interoperable WiSA modules compatible with the WiSA transmit technology.

Speakers, with the matching “RX” model, receive the wireless audio signal and processes it for audio play out. ​ 3 Table of Contents The WiSA Opportunity We believe that the following attributes: cost, mobility, video support, ease of installation and quality create a market opportunity for WiSA’s technologies to be adopted by the consumer electronics industry as described further below.

Cost We believe that the simplicity and cost structure of both our original technology and our embedded software solution will make our prices competitive for a wider range of applications in their respective markets, allowing consumer electronics companies to integrate our technology, while also delivering high quality audio.

Video Support Wireless audio capable of supporting video has become a priority for consumers across a variety of high-volume multimedia platforms, including TV’s, smartphones, game consoles and set-top boxes. Video applications require audio and video to be perfectly synchronized in order to avoid lip-sync and speaker audio phase distortion issues.

WiSA’s technology prioritizes wireless robustness, latency and speaker synchronization to create an entertaining experience. Ease of Installation We believe that the home entertainment market has moved toward simplicity in recent years. The costly and inconvenient home theaters of the past have left consumers with a desire for audio systems that provide a simplified installation process.

We believe that as the TVs adopt broad use of Dolby Atmos and Dolby Atmos Music, which delivers the immersive audio decoding, new audio systems, including the predominant sound bar system, will need to provide a higher level of performance, especially in the surround-sound market. WiSA’s technology greatly simplifies the installation process of true surround-sound systems.

This allows consumers to install an immersive audio system with the same amount of effort as a sound bar, but enjoy a far superior experience.

We believe that an overwhelming majority of the content entering consumers’ homes through digital TV and streaming services is provided in a multi-channel format, which is why WiSA’s goal is to facilitate enjoyment of true surround sound for both the everyday consumer and audio enthusiast.

In addition to easy installation, WiSA’s technology provides consumers with a multitude of options, allowing customization of the immersive audio experience individualized to each consumer, without being forced to stick with one brand of speaker.

For example, our hope is that a consumer might start with a WiSA enabled sound bar for their TV and then add a WiSA enabled subwoofer. That same system can be easily upgraded to a variety of surround sound systems by simply adding more speakers.

Our technology will allow consumers to upgrade an audio system or just one component of the system without the need to replace the entire system. Consumers can keep the original transmitter, sound bar, and subwoofer and integrate them seamlessly into a new system.

Being able to outfit a home entertainment system with WiSA-enabled speakers and components gives consumers the ability to express their individual preference and needs and provides the assurance that the devices will interoperate, delivering what we believe is the highest standard in HD wireless surround sound. 4 Table of Contents Dissatisfaction with Bluetooth Performance and Quality We believe that consumers want better performance and quality from their Bluetooth audio devices.

For example, they may want headsets that stay connected over longer distances or products that offer better audio fidelity. By offering a solution that addresses these needs at a comparable price point to Bluetooth, we believe that we can build consumer demand for our technology.

The address of our corporate headquarters is 15268 NW Greenbrier Pkwy, Beaverton, OR 97006. Our website address is www.wisatechnologies.com .

The information contained in or accessible through our website is not part of this Report and is intended for informational purposes only. We are an emerging technology company and our primary business focus is to enable mainstream consumers and audio enthusiasts to experience high quality wireless audio.

We intend to continue selling our proprietary wireless modules to consumer electronics companies while also expanding our focus to implement a lower cost solution by porting our IP software onto commercially available internet of things (or IoT), modules with integrated Wi-Fi technology. 16 Table of Contents Our technology addresses some of the main issues that we perceive are hindering the growth of the home theater: complexity of installation and cost.

We believe that consumers want to experience theater quality surround sound from the comfort of their homes. However, wired home theater systems often require expensive audio-visual (or AV), receivers to decode the audio stream, leaving the consumer with the burden of concealing the wires.

Hiring a professional to hide the wires into the walls or floor is invasive, complicated, costly and time consuming. Further, people who rent as opposed to own may not be able to install these systems as the installation construction needed may not be permitted under a lease agreement.

Our first-generation wireless technology addresses these problems by transmitting wireless audio to each speaker at Blu-ray quality (uncompressed 24-bit audio up to 96 kHz sample rates) and emphasizing ease of setup.

To our knowledge, our custom chips and modules technology is one of the few technologies available today that can stream up to eight (8) separate wireless audio channels with low latency, removing lip-sync issues between the audio and video sources.
