POWERSOFT DEBUTS ‘EARTH-SHAKING’ NEW PRODUCT AT ISE

February 18, 2019 News

Powersoft uses this year’s ISE as the first chance to demonstrate its new product, Mover – a small yet powerful linear transducer that can be used in audio applications and as a linear motor / shaker. 

Adaptable to various purposes, including 4D cinemas, theme parks, or venues with vibrating acoustic floors – as well as applications that go beyond entertainment – Mover lets audiences feel the sound through haptic perception by vibrating the surrounding environment, which the human body picks up and, through bone conduction, translating the vibrations into perceivable frequencies. 

Mover is available in two versions; Direct Drive and Inertial Drive. With Direct Drive, Powersoft adds a unique and unprecedented experience in which the transducer is anchored to an immovable surface and the moving magnet is directly connected to a movable surface, such as a floating floor or chair. Along with exciting the surface, Direct Drive is also able to create an offset of +/- 15 mm. As a result, the surface will not only shake but also move giving the audience the sensation of falling off or jumping over an object.

The Inertial Drive version can be mounted directly to a surface. The ultra-low frequency reproduction and unmatched efficiency of Mover – Inertial Drive will excite the surface and extend the low frequency experience. Mover is also available in a low impedance and 100 Volt version. 

Mover is based on Powersoft’s patented moving magnet linear motor technology. Extended power handling, electromagnetic conversion, reliability and maximum SPL are a few of the features and improvements with respect to conventional moving coil arrangements. This patented technology can also be found in the M-Force, which has found its way into earth quake simulators as well as powerful subwoofers. 

Powersoft has now been able to pack this unique technology into Mover for applications where a shorter travel and less force is required. Mover is more accurate, powerful and efficient compared to existing products. It can be used to move floors or seats, both to track video content as well as transfer audible frequencies. 

Mover can be used in conjunction with a Powersoft amplifier which, when used with Mover-specific firmware, can generate specific subharmonics. This new algorithm transposes the pitch of the frequencies down in order to reproduce ultra-low frequency extension all the way down to 5 Hz.

With the integration of the Mover many experiences such as rides, simulators and movie watching can benefit from fast and accurate movements that are in sync with the complete experience. Existing solutions for this suffer either from limited speed, harmonic distortion or limited frequency range.
