FLAT CORE SPEAKER TECHNOLOGY

Introducing our patented Flat Core Speaker technology. FCS technology enables unprecedented possibilities for innovation across industries. Resonado's tech differentiates itself from previous attempts by repositioning the magnetic force. Instead of using a cylindrical magnet with the voice-coil around it, FCS tech uses bar magnets with a flattened voice-coil in the middle, thereby creating vertical oscillations. Watch the video below to listen to Christian Femrite, our VP of Engineering, explain how it works and play a demo of our 10 Watt speaker prototype. 

 
 

Over the past few decades technological advancements have introduced waves of new products; each one thinner, lighter, and more efficient than the last. From consumer electronics such as phones and televisions to the automotive industry.

However, one component that all of these products share that has remained underdeveloped is the speaker. Virtually all products that emit sound use the original 140-year-old cone-shaped speaker technology, mostly due to cost advantage. This is why the volume icon has that familiar cone-shape. Resonado introduces the solution: A flat core speaker that enables products to fully continue the trend of becoming thinner, lighter, and more efficient.

FCS takes a completely different approach to electromagnetic optimization problem presented when designing a space-efficient speaker with high quality sound. The fundamental design uses a flattened voice coil coupled to both the diaphragm and an underlying suspension which is flanked by vertically-magnetized bar magnets, as shown below.

FCS technology is an innovative speaker technology that provides the following key advantages over existing speaker technology:

Advantage: Material, Energy, and Space Efficiency

 

30% more sustainable thanks to minimizing rare earth metal use such as neodymium and copper. 

40% more energy efficiency. FCS packs significantly more electromagnetic induction into a smaller space. This translates into more efficient reproduction of sound from a high-sensitivity device with crisper response.

30-70% thinner and lighter thanks to our core, innovative structure. The redesigned voice coil arrangement permits more power handling in a smaller space. Any speaker made with FCS technology could be made thin using our proprietary multi-core design.

 

Advantage: Structural Flexibility

The old, cone-shaped diaphragm has inherent structural disadvantages due to the unused space it creates within the product. This structural disadvantage of the cone-shaped speaker requires engineers to allocate a predefined space in their products, limiting their product designs. For special applications, FCS speakers can be created in unique bent and curvy shapes. This is an area we are actively exploring, but FCS offers the unique ability for a driver to be precisely designed for a specific slot or allocated space, no matter how oblique or contorted.

 

Advantage: Sound Quality

Advantage: Scalability

FCS tech can be made into any size and reproduce the full frequency range, from tweeters to subwoofers. Additionally, it’s important to note greater ease of manufacturing as well. Conventional drivers must be meticulously aligned in two dimensions (to ensure that the voice coil will never touch the magnet while suspended in the gap. FCS drivers must only be aligned side-to side in one dimension. This inherently leads to easier defect detection, as any defects are clearly visible from the underside of the FCS driver. This reduces defect rates by an order of magnitude from conventional technology. 

 

Existing Technology

Conventional dynamic loudspeakers have some strengths which have pushed it to where it is today, but also some weaknesses that leave more to be desired. Though this is a non-exhaustive list, a couple of each are mentioned here.

  1. Strengths

    1. Cost Effectiveness: Over the years, speakers have been developed with practically any material imaginable ranging from styrofoam to glass. Manufacturers have arrived at cost-effective ways to provide high-quality sound.

    2. Diaphragm and Cone Stiffness: Though there are still surface modes which give rise to nonlinear distortion, the cone-shaped design certainly provides a degree of stiffness due to its concave structure and generally highly compressible air volume.

  2. Weaknesses

    1. Sound Dispersion: Many of the designs on the market focus on the on-axis frequency response as the highest authority on the performance of a speaker. It isn’t always the case that a listener is perfectly stationed on the perpendicular axis from the speaker, so there are often issues that arise with high frequency sound distribution around a larger room.

    2. Incomplete Frequency Response: There aren’t many, if any, individual drivers that independently can reproduce the entire audible spectrum efficiently. There are a number of partial solutions such as built-in crossovers with 2-way and 3-way systems, waveguided enclosures, and even coaxial drivers, but they all add further complexity.


This tech is not the first to adopt a planar diaphragm for the speaker. In fact, there have been other attempts over the past decades. While these previous attempts succeeded in creating speaker drivers that are thinner, they could not replace the existing cone-shaped speaker drivers due to their high cost of manufacturing and lack of scalability.

Although there have been other speaker structures invented, we're the first to be in a position to overtake the market dominance of the original speaker.

Please feel free to watch this video for a more in depth explanation of how the tech works and how it compares to other existing technologies.

 

 

Resonado ushers in an iconic change with the potential to foster innovation across every industry you can think of: from alarm clocks, to cars, to planes, to concerts, to entire stadiums. 

In the midst of rapid technological development, conception of technology varies greatly among different generations. Take the save icon or the call icon for example. Our generation hardly knows what a floppy disk is or even a dial phone. It's time to introduce innovation to the sound industry to where the next generation will hardly know what a cone-shaped speaker is.
