Systems and methods for acousto-haptic speakers

Abstract

The systems and methods described herein relate to, among other things, a transducer capable of producing acoustic and tactile stimulation. The transducer includes a rigid mass element disposed on the diaphragm of a speaker. The mass element may optionally be removable and may have a mass selected such that the resonant frequency of the transducer falls within the range of frequencies present in an input electrical audio signal. The systems and methods advantageously benefits from both the fidelity and audio performance of a full-range speaker while simultaneously producing high-fidelity, adjustable and palpable haptic vibrations.

Background technique [0004] Today, there is a growing need to supplement additional sensory stimuli to multimedia systems that present audio and visual data to users. Multimedia systems, such as televisions, portable devices and video games, are being enhanced by the introduction of improved screen and network capabilities. In addition to these more traditional areas of improving user experience, another area of ​​consideration is tactile stimulation. Combined with improved audio and visual effects, haptic stimulation can make gaming or movie experiences much more realistic and memorable. [0005] Currently, ...
