Headphone amplifier for VR goggles

VHA-5240B is a headphone amplifier developed for VR goggles, which now make it easy to enjoy 3D images.
 
 
By increasing the amount and accuracy of auditory information in the VR (Virtual Reality) world, VR viewing can be made more realistic. the VHA-5240B reproduces the surround sound used with accuracy, precision, and no time lag and the flat phase characteristics that emphasize the localization of binaural recordings used in VR clearly reproduce the sense of direction and distance, adding a further sense of reality to the virtual reality world.
 
 
Depending on the model of the VR goggles, there are stereo earphone output types and separate left and right mono earphone output types. In addition to stereo input and output, it also has separate left and right mono input and output to accommodate each type of goggle. VHA-5240B does not have a volume control (gain controller) because it is designed to be used with goggles with volume control. The case is made of conductive carbon-laced filament to prevent induction noise.
 
 

From the virtual world to the real world

The amplifier built into the VR goggles is loaded by the use of earphones. The heavier the load, the worse the effects, such as increased distortion, worse transient characteristics, and worse delay time. By precisely controlling the bias current, the VHA-5240B maximizes the amount of information and increases the accuracy. Furthermore, by widening the bandwidth and using a non-feedback circuit without negative feedback, transient distortions such as TIM distortions are eliminated and time delays are minimized to the utmost limit, thereby eliminating phase distortions and enabling accurate representation of surround sound localization. This allows the VHA-5240B to be connected to the earphone output of the goggles to reduce the load when using earphones and prevent deterioration of the characteristics. By omitting the gain controller, the VHA-5240B raises the input impedance 100 times higher than the VHA-5240A. For this reason, it can expect further improvement in accuracy and increase in the amount of information compared to the 5240A. The earphones are driven by a precision driver circuit that extracts pure signals with no deterioration in characteristics. This makes it possible to precisely reproduce the phase and time information necessary for VR, and to realistically reproduce the world of virtual reality.
