Abstract
A multi-functional feedback device, a haptic feedback system, and augmented reality (AR)/virtual reality (VR) glasses are provided. In the multi-functional feedback device, a vibration unit and a touch unit are assembled in a housing and share a magnetic circuit unit, which not only realizes transmission of a sound signal, but also realizes haptic feedback through a vibration signal, achieving a multi-functional feedback effect. Due to sharing a same magnetic circuit unit, costs can be saved, and an occupied space can be saved. The haptic feedback system includes the multi-functional feedback device. The vibration unit and the touch unit can be separate power amplifiers or a common power amplifier. In the AR/VR glasses, the haptic feedback system is assembled in a glasses frame, which can realize a reminder through vibration or sound on a head when used by a user, so as to meet diverse requirements.
