Abstract: A head-mounted wearable device (HMWD) with a form factor of eyeglasses incorporates a compact audio module with transducers that may be operated as an acoustic dipole or acoustic quadrupole. The audio module provides ducts that convey sound with a particular phase from a transducer to particular output ports. The phase of sound emitted from a first output port is opposite to the phase of sound emitted from a second output port. The audio module may include a pair of transducers, enabling operation as an acoustic dipole or quadrupole. The ducts are integrated into elements of the structure of the audio module, minimizing the overall size of the audio module.

Abstract: A head-mounted wearable device incorporates a transducer into a nosepiece. Vibrations from the user's speech are transferred through the bridge of the nose and are detected by the transducer to produce an audio signal. In one implementation, a nose plate with a pair of attached nosepieces is mounted to a transducer, such as an accelerometer. The nose plate may be affixed to a front frame of the head-mounted wearable device using a motion limiter mechanism.

Abstract: A head-mounted wearable device (HMWD) may be fashioned that includes temples that pass near each ear of the user. A temple may incorporate a bone conduction speaker (BCS) to provide audio output to the user. During wear, a portion of the BCS is in physical contact with a head of the user to transfer the vibrations from the BCS to the user. To accommodate different head shapes and sizes, a head contact piece may be mounted to the BCS. The user may add, remove, or swap the head contact piece from an assortment of such pieces to find a profile that is comfortable to the wearer and improves performance of the BCS. The head contact piece may be magnetically affixed, allowing for easy changeout.

Abstract: A user interface for a head-mounted wearable device provides many functions to a user. Information about whether the device is being worn (donned) or not worn (doffed) may be acquired in several ways. Force sensing resistors in the device may provide output indicative of the pressure associated with wearing the device. Output from a bone conduction (BC) microphone may be analyzed to determine if the device is in use. Piezoelectric BC speakers typically used to present audio output to a wearer provide changes in voltage corresponding to a change in pressure associated with wearing the device. A BC speaker may emit a signal that is detected by the BC microphone, with changes in the signal strength being used to determine if the device is donned or doffed.
