At ISE 2019, Powersoft will be presenting its new product, Mover, a 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 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. It can be used to move floors or seats, both to track video content as well as transfer audible frequencies.  

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.  

A press conference to officially announce Mover will take place on Powersoft’s stand at 3.30pm local time on Tuesday February 5. Visitors to Hall 7, Y195 -– one of Powersoft’s three booths at ISE – will be able to experience Mover first hand on a custom-built platform as it interacts with VR content. Users standing on the platform and wearing the requisite HTC headset can experience an immersive 360° video while being stimulated through haptic perception. 

Mover is available in two versions; Direct Drive and Inertial Drive. With Direct Drive, 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. Next to 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. With the ultra-low frequency reproduction and efficiency of Mover, the Inertial Drive can 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, introduced in 2013. Extended power handling, electromagnetic conversion, reliability and maximum SPL are a few of the innovative features and improvements Mover has made upon the conventional moving coil arrangement. This patented technology can also be found in the M-Force, which has found its way into earthquake simulators, as well as powerful subwoofers. Powersoft has now been able to integrate this technology into Mover for applications where a shorter travel and less force is required.

Mover can be used in conjunction with a Powersoft amplifier as Powersoft has introduced an updated firmware version to the product, as well as a specific subharmonic generator plugin. This new algorithm transposes the pitch of the frequencies down in order to reproduce the ultra-low frequency extension down to 5 Hz.
