Headphone volume adjustment in display apparatus
The patent US12067327B2 describes a display apparatus that integrates advanced audio processing capabilities for headphone use. The apparatus includes a display panel, a display controller, and an audio interface equipped with a detection circuit. This circuit identifies when headphones are connected and enables an audio-processing chip to adjust the output audio signal based on a predefined headphone-volume setting. The adjustment process involves two distinct mechanisms that modify the audio signal strength through a series of steps, ensuring a gradual transition to a target sound strength. The first mechanism employs a steeper slope for volume reduction compared to the second, allowing for a controlled audio experience.
Additionally, the patent outlines a method for headphone volume adjustment that includes detecting the impedance of the connected headphones. Depending on the impedance type, the audio-processing chip selects an appropriate driving voltage to optimize audio output. The display controller facilitates user interaction through an on-screen display (OSD) that allows for volume adjustments represented on a scalar bar with multiple sound levels. The audio-processing chip activates the corresponding volume adjustment mechanism based on the selected sound level, ensuring that the output audio signal is maintained or adjusted appropriately according to user preferences. This innovative approach enhances the user experience by providing tailored audio settings for different headphone types.
