Abstract
Speaker assemblies for a headphone device may include an audio speaker configured to produce audible sound in response to receiving an audio signal at the audio speaker. A tactile bass vibrator distinct from the audio speaker may be operatively connected to the audio speaker. The tactile bass vibrator may be configured to produce tactile vibrations in response to receiving the audio signal at the tactile bass vibrator. A current divider may be operatively connected to the audio speaker and the tactile bass vibrator, the current divider providing greater electrical resistance to flow of current to the audio speaker than to flow of current to the tactile bass vibrator.
