The first light beam is extracted through the corresponding first mapping zone and transferred to the corresponding first key. The second light beam is transferred to the second key.

This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.

The illuminated push-button switch device includes a shell-portion enclosing a switch element and a light source and having one or more opening-portions protruding from an upper surface of the shell-portion; a button-portion provided to cover the opening-portions, the button-portion being vertically movable along the opening-portions; and a panel-portion surrounding an outside of the button-portion and provided on the upper surface of the shell-portion, wherein gap is provided between the panel-portion and the button-portion in a top view, wherein the upper surface of the shell-portion extends along a plane perpendicular to a vertical movement direction of the button-portion, and a slope-portion at a predetermined angle with respect to the upper surface is formed on a portion of the upper surface situated under the gap, and wherein a height of the slope-portion along the vertical movement direction gradually decreases from a button-portion side to a panel portion side.

Disclosed is a switch device including a push operation part having a light transmitting portion, a control board installed in a push operation direction of the push operation part, a fingerprint sensor provided on the push operation part to detect a fingerprint of a user pushing the push operation part, a controller provided on one surface of the control board to control the fingerprint sensor, a flexible board provided to electrically connect the fingerprint sensor and the controller, and a plurality of light sources installed on opposite surfaces of the control board and closer to the push operation part than the controller to illuminate the light transmitting portion.

An illuminated glass keycap having a glyph diffuser layer that may diffuse light through a glyph window opened in a background layer. The background layer may be opaque and the glyph window may be transparent. The keycap is adhered to a scissor mechanism positioned above electrical switch circuitry. Included within, below, or adjacent to the scissor mechanism may be one or more light sources positioned to emit light through the keycap, around the perimeter of the keycap, and/or through the background layer.

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 switch device includes a main module, which includes at least one main electronic control circuit, connections to the electrical system of a building and/or to equipment or devices to be controlled, one or more touch sensors or contacts connected to the at least one main electronic control circuit, a main box-shaped housing element for the preceding components, and one or more systems that provide a reversible electric or electronic and mechanical connection of the main module to an accessory module.

The present inventors have recognized that an electrical switch for opening doors in buildings, calling elevators, and the like can be improved to require less physical contact, larger activation area, and multiple activation methods, with increased reliability, by utilizing a piezoelectric sensor specifically arranged between rigid, parallel mounting plates in which one of the plates (an inner plate) is rigidly fixed to prevent movement while the other plate (an outer plate) is accessible for receiving physical contact. By rigidly fixing the inner plate, such as by mounting to a wall or bollard, the sensor can react with sensitivity upon an application of less pressure on the outer plate. Such pressure compresses the sensor between the plates to produce an electrical signal. A controller receiving the signal can, in turn, execute to open a door, call an elevator and/or activate a light or sound to provide feedback.

A switch panel for an aircraft includes a cover and aback plate. A distance from the cover to the back plate is a thickness of the switch panel. In some cases, the thickness is less than about 9.525 mm. A button assembly for a switch panel for an aircraft includes a button base, a button retainer, and a lens. The button base includes a bottom end, a base side, and a transition portion between the bottom end and the base side. In certain cases, the transition portion of the button base is beveled or radiused with a sloped or concave shape.

An illuminated keyswitch structure with an illuminating module includes a base plate, a drive circuit board under the base plate, a spacer between the drive circuit board and the base plate, and a light-emitting part on the circuit board. The spacer has a through hole communicating with an opening of the base plate in a vertical direction. The light-emitting part is located in the through hole, and falls within a projection of the opening in the vertical direction. The light-emitting part has a top surface that is lower than or equal to a bottom surface of the base plate in the vertical direction. The structure of the illuminated keyswitch structure around the light-emitting part can keep flat by the spacer. The spacer can prevent the light-emitting part from structurally entering the opening, avoiding structural interference between the light-emitting part and other components above the base plate.
