An electronic device includes a display element, a piezoelectric element, and a cushioning element. The display element has a display surface and a non-display surface opposite to the display surface. The piezoelectric element is disposed on the non-display surface. The cushioning element is disposed between the display element and the piezoelectric element, and a space is surrounded by the display element, the piezoelectric element, and the cushioning element.

A planar coil linear actuator/transducer. A stack of individually driven planar coils are used. A common core passes through the center of the stack of coils. A mobile magnet resides in the core. The coils are selectively energized in order to drive the magnet as desired. It is possible to control both frequency and amplitude by controlling the motion of the magnet. In a preferred embodiment, each planar coil is created as a copper (or other conductive material) trace on a multi-layer printed circuit board.

An apparatus can include a display member configured to display an image, a vibration apparatus disposed at a rear surface of the display member, a supporting frame disposed at a rear surface of the vibration apparatus, and an adhesive member disposed between the supporting frame and the rear surface of the display member. In addition, the adhesive member and/or supporting frame is spaced apart from the vibration apparatus, and the vibration apparatus is configured to vibrate in a direction toward the display member.

A voice-controlled electronic device that includes a device housing having a longitudinal axis bisecting opposing top and bottom surfaces and a side surface extending between the top and bottom surfaces. The device can further include one or more microphones disposed within the device housing and distributed radially around the longitudinal axis; a processor configured to execute computer instructions stored in a computer-readable memory for interacting with a user and processing voice commands received by the one or more microphones and first transducer and second transducers configured to generate sound waves within different frequency ranges.

A system for indicating a direction to a user is disclosed. The system may include a first unit and a second unit to be worn proximate to a first ear and a second ear of the user respectively. The system may indicate a direction to the user through tactile sensations delivered proximate to the ears of the user by the first and second units. The system may also include microphones to aid in determining the direction of a source of a sound and the system may indicate the determined direction, thereby allowing the user to localize the sound. The system may also function as hearing aids. The system may aid individuals with hearing disabilities by alerting them to the direction of the source of a sound.

Systems and methods are disclosed that provide directional speakers and haptic devices for each guest of a ride vehicle. A controller may receive a vehicle location, seat location data, input audio data, and input haptic data. The seat location data may include a guest's seat location in the ride vehicle and/or the guest's preferences (e.g., a preferred language, volume preferences, or content rating preference). The controller may generate different audio output signals corresponding to different guests based on the input audio data, the vehicle location, and/or the seat location data, and generate different haptic output signals corresponding to different guests based on the input haptic data, the vehicle location, and/or the seat location data. The controller may then instruct directional speaker directed at the seat locations of the different guests to output the different audio output signals and instruct haptic devices directed at the seat locations to output the different haptic output signals.

A display apparatus is disclosed. The display apparatus includes a display panel, a supporter attached to a rear surface of the display panel, and a piezoelectric vibration unit including a fixing portion attached to the supporter and a cantilever portion overhanging from the supporter.

A display device includes: a display panel including a pixel array layer on one surface of a first substrate for displaying an image; a sound generator for transmitting an ultrasound; and an ultrasonic sensor for receiving an ultrasound reflected by an object on the display panel. The sound generator and the ultrasonic sensor are on the other surface of the first substrate opposite to the one surface of the first substrate. The ultrasonic sensor includes a plurality of ultrasonic sensor units arranged in a matrix form, and the ultrasonic sensor senses the object using the reflected ultrasound received by the plurality of ultrasonic sensor units.

The application describes techniques for adaptively setting a threshold that will be used to determine the gain applied to a haptics signal.

An electromagnetic actuator includes an inner magnet arranged relative to an axis, an outer magnet arranged a radial distance from the axis, an inner radial wall of the outer magnet facing an outer radial wall of the inner magnet, the inner and outer radial walls being separated by an air gap, a voice coil arranged in the air gap separating the inner and outer magnets, and an actuator coupling plate attached to the voice coil. During operation of the device electrical activation of the voice coil causes axial motion of the actuator coupling plate.
