AI Technical Summary
Technical Problem
Existing in-vehicle display devices have a narrow noise frequency band during haptic feedback, which is the same as the vibration frequency of the drive module, resulting in noise amplification and affecting the user experience.
Method used
Multiple isolation units are set between the display module and the housing to form a small-sized cavity. The cavity is separated by the gap between the isolation units and the inner wall of the housing, and combined with sound-permeable holes, damping layers and Helmholtz cavities, noise is absorbed and suppressed.
Benefits of technology
It effectively reduces noise caused by chamber resonance, thus improving the user experience.
