Abstract:
A virtual reality head-mounted display is disclosed which comprises an inflatable lining module disposed within a frame of a monitor main body coupled with a positioning band. The inflatable lining module is composed of a foam body, an inflatable cushion, an air passage, an air pump, an air pressure sensor, a contact sensor and a control module. When the contact sensor detects an external pressure, it sends an enabling signal to the control module to drive the air pump to operate, and an air is introduced to the inflatable cushion through the air passage to inflate the inflatable cushion, so that the form of the foam body is correspondingly adjusted. When the air pressure sensor detects the pressure inside the inflatable cushion higher than a specified threshold interval, it sends a disabling signal to the control module, and the air pump is accordingly controlled to stop operating.

Claim (Index 11):
The virtual reality head-mounted display according to  claim 10 , wherein the piezoelectric air pump comprises:\n a gas inlet plate comprising at least one inlet, at least one convergence channel and a central cavity, wherein a convergence chamber is defined by the central cavity, and the at least one convergence channel corresponds to the at least one inlet, wherein after the air is introduced into the at least one convergence channel through the at least one inlet, the air is guided by the at least one convergence channel and converged to the convergence chamber; a resonance plate having a central aperture, wherein the central aperture is aligned with the convergence chamber, wherein the resonance plate comprises a movable part near the central aperture; and a piezoelectric actuator aligned with the resonance plate, wherein a gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber, wherein when the piezoelectric actuator is driven, the air is introduced into the air pump through the at least one inlet of the gas inlet plate, converged to the central cavity through the at least one convergence channel, transferred through the central aperture of the resonance plate, and introduced into the first chamber, wherein the air is further transferred through a resonance between the piezoelectric actuator and the movable part of the resonance plate.
