The speakers can apparently boost EV range and provide “personal bubbles” for each passenger with “virtual headphones.”
- A British audio speaker company claims its in-vehicle sound technology can boost range for electric vehicles with lighter weight and less energy consumption.
- Apparently, "electrostatic speakers" can generate "personal bubbles" within the cabin, reducing noise interference.
- Reports indicate that they are set to appear in an upcoming electric vehicle this year, with speculation suggesting it might be the fully electric Range Rover.
Car manufacturers worldwide continuously seek methods to extend the driving range of electric vehicles. Established approaches include high-capacity battery modules, energy-efficient engines, and sleek body shapes. Nevertheless, an innovative UK-based firm asserts it possesses a fresh, unconventional approach that could possibly enhance the distance capability of your EV.
Uh, that would be energy-efficient speakers.
British firm Warwick Acoustics claims its sound technology can enhance the driving range of electric vehicles by up to 20 miles more than conventional audio systems. This improvement in range is due to the use of lightweight "electrostatic speakers," The Independent Initially reported on Thursday, they have incorporated these speakers into a prototype. Polestar 2 , boasting a claimed reduction of 90% in weight, consuming 90% less energy, and achieving full recyclability. Of course, these figures could vary depending on factors such as battery size and overall vehicle weight.
Electrostatic speakers
It is said that the speakers are extremely slim, making their packaging straightforward and efficient. According to the company, these speakers are set to appear in a production car later this year. Rumors suggest they might debut in an upcoming fully electric Range Rover model as reported by the media outlet.
Warwick Acoustics explains in a blog Electrostatic speakers produce sound through an electrically charged, extremely thin membrane positioned between two metallic plates. An audio signal generates an electrostatic field which causes this membrane to move, thereby generating sound waves. In theory, they are said to provide superior clarity with minimal distortion.
In contrast, conventional speakers employ coils and magnetic fields for sound production. However, the company claims these components possess excessive weight and numerous movable elements, leading to distortions.
According to the company, when placed inside a headrest, conventional speakers face constraints with regard to frequency range and coverage area. "An electrostatic speaker allows for shaping the diaphragm across the whole surface of the headrest," enabling each occupant to experience "a precisely tuned sound field, eliminating the issue of audio fading as you move your head."
This feature can establish "individual spaces" for each occupant without causing "audio interference." Therefore, if the driver needs to take a call, rear passengers can keep listening to their music undisturbed. As such, everyone can enjoy their preferred tunes or volume settings without conflict.
Car manufacturers have been intensely focused on enhancing electric vehicles' efficiency by eliminating superfluous elements, minimizing part counts, employing massive one-piece castings for significant sections of the chassis, and adopting a simplified production method akin to what Tesla has implemented, with an aim towards boosting both range and performance. Additionally, innovative ideas from component makers are beginning to emerge. However, you can be confident that beloved audio systems will remain intact in these vehicles.
If the electrostatic speakers indeed find their way into the electric Range Rover as speculated, we will definitely test them out to determine whether they can compete with top-tier brands such as Meridian, Burmester, Bose, and others in the realm of high-end audio systems.
