A sports-team related display is an apparatus that is used to decorate a room or area. The apparatus is configured to allow for a user to play the music or chant associated with the related team. The present invention includes a sport-ball-shaped ornament, an audio box, and an ornament holder. The sport-ball-shaped ornament is a model of an athletic ball, such as a football, baseball, soccer ball, or any of a variety of other sports balls. The audio box is a series of electrical and structural components that provide the present invention with the ability to store and play prerecorded team songs and chants. The ornament holder is a mounting device that can support the present invention above a table or other flat surface. This allows positioning of the sport-ball-shaped ornament, and simultaneously prevents the sport-ball-shaped ornament from rolling or moving unexpectedly.

A system and method for electronic greeting cards includes receiving a selection of a background image, obtaining visual media to overlay on the background image, obtaining a personal message to overlay on the background image, obtaining a signature to overlay on the background image, and displaying the electronic greeting card. Displaying the electronic greeting card includes displaying the background image, displaying the visual media over a first portion of the background image, displaying the personal message over a second portion of the background image, and displaying the signature over the background image. In some embodiments the visual media is a drawing including a sequence of drawing strokes recorded when the drawing was obtained. In some embodiments, the personal message is displayed as text at a reading speed. In some embodiments, the signature includes a sequence of strokes captured when the signature was obtained.

A pulsating imitation speaker includes a fixed cover, a flexible cover, and a motor and gear assembly having a motor with a motor shah, a first gear on a first axle, and a second gear on a second axle. The motor is drivingly engaged with the first gear via a pinion on the motor shaft and the first gear is drivingly engaged with the second gear such that when the pinion is rotated by the motor, the first and second gear also rotate. The pulsating imitation speaker further includes an actuator fixedly engaged with the flexible cover and a first and second circular member each engaged with the actuator and respectively positioned on opposite ends of the second axle such that the circular members rotate with the second gear. The actuator is reciprocated by rotation of the circular members such that the flexible cover moves relative to the fixed cover, when the motor is activated.

A voice module of a television collects environmental volume Vr of an environment where a user is located; first current volume Vc of the television is obtained and compared with the environmental volume Vr, so as to determine whether the television volume needs to be adjusted; a desired volume value of the television requiring volume adjustment is calculated by means of a volume curve dynamic adjustment algorithm, and the television automatically adjusts its volume to the desired volume value.

Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip in which a pad barrier layer caps a pad of a piezoelectric device. The pad barrier layer is configured to block hydrogen ions and/or other errant materials from diffusing to the piezoelectric layer. Absent the pad barrier layer, hydrogen ions from hydrogen-ion containing processes performed after forming the pad may diffuse to the piezoelectric layer along a via extending from the pad to the piezoelectric device. By blocking diffusion of hydrogen ions and/or other errant materials to the piezoelectric device, the pad barrier layer may prevent delamination and breakdown of the piezoelectric layer. Hence, the pad barrier layer may prevent failure of the piezoelectric device.

Articles of manufacture, systems and methods facilitating sound diode receptacles are provided herein. In one embodiment, an article of manufacture comprises: an inner wall; an outer wall, wherein the inner wall and the outer wall form a double walled receptacle; a speaker device located in an inner region of the receptacle; and a control device having circuitry disposed in an inner region of the receptacle and configured to generate an output of sound that is emitted from the speaker device.

A microphone with integrated speaker which includes a front casing with a front connecting portion and a front handle portion having a battery opening; a rear casing with a rear connecting portion and a rear handle portion connected to the front casing to form a first cavity with a cylindrical connecting portion and a cylindrical handle portion with a second cavity; a metallic net cover coupled with the cylindrical connecting portion; a vocal pickup support arrangement provided inside the metallic net cover between the front connecting portion and the rear connecting portion in which a vocal pickup unit is provided; a speaker positioned inside the first cavity; a pair of electrode plates positioned inside the second cavity; a circuit board affixed on the front casing; a battery cover detachably connected to the front handle portion; and an aluminum alloy handle covers the cylindrical handle portion.

A noise control system for a ducted rotor assembly, the ducted rotor assembly including a hub, a duct, and two or more blades coupled to the hub and supported by the duct. The noise control system including a microphone configured to receive a sound input generated by the ducted rotor assembly, the microphone configured for association with the hub; a speaker unit configured to generate a cancellation noise, the speaker configured for association with the hub; and a controller operably connected to the microphone and the speaker unit, the controller configured to selectively adjust harmonics of the cancellation noise to reduce an acoustic signature of the ducted rotor assembly. In another aspect, there is provided a rotorcraft with a ducted rotor assembly in a tail portion including a noise control system. In a third aspect, there is a method of reducing an acoustic signature of a ducted rotor assembly.

A gas detection device includes an enclosure having an interior chamber, an audio loudspeaker in acoustic communication with the interior chamber of the enclosure, and a gas sensor configured to detect a gas within the interior chamber of the enclosure. The device may include a ventilation port configured to permit two-way gaseous communication between the interior chamber and an atmosphere external to the enclosure, where the atmosphere comprises the gas. The audio loudspeaker is configured to generate a pressure within the interior chamber. The pressure causes a portion of the external atmosphere to be drawn into the interior chamber via the ventilation port. The gas sensor may include an emitter and a receiver. The gas detection device can be integrated into a mobile electronic device, such as a smartphone or tablet computer.
