An apparatus and method allow end users to interactively create complex lighting patterns by remote control. Applications include decorative lighting, landscape lighting, signage, or advertising platforms. A lighting control system can be equipped with sensors that can receive remote control signals from a variety of different sources, and route the control signals to modulate receptacles coupled to different lighting circuits, thereby independently controlling multiple light arrays to achieve separate light patterns, or to coordinate different lighting effects. Interactive remote control can be provided via a mobile computing device such as a smart phone running a customized program. In one embodiment, the remote control device communicates selections to a Bluetooth®-equipped speaker to produce sound-controlled lighting effects.

This disclosure relates to a device and a method for controlling sound play, and a system associated therewith. The device includes a brainwave detector, a selector and a switcher. The brainwave detector is arranged to detect brainwave information of a user. The selector is arranged to select a sound player to be used from a first sound player and a second sound player based on the brainwave information. The switcher is arranged to send a switch control signal according to a result of the selection so as to cause the selected sound players to play the sound. By selectively switching on a sound player based on the brainwave information of the user, the sound play mode adapts to personal state or expectation of the user.

A lid including one or more messages relating to a product is provided. The lid can store and play one or more audio messages on an audio device attached thereto. The audio messages can be recorded onto the audio device, loaded onto the audio device at a point of sale, and/or pre-loaded on the audio device at a factory. The lid can also include one or more visual and/or surface texture indicia corresponding to the product, such as the product name, color(s) uniquely corresponding to the product, and/or the like.

A person support apparatus, such as a bed, cot, stretcher, or the like, includes an active noise cancellation device configured to generate a noise cancelling sound wave that is designed to cancel a noise sound wave. The active noise cancellation device may include speakers and a microphone. In other embodiments, the person support apparatus includes a sound emitting component and a transmitter adapted to send out a notification signal prior to activation of the sound emitting component. The notification signal provides information about a characteristic of the sound to be emitted by the sound emitting device. The recipient of the notification signal may then use the signal to cancel the sound that is to be emitted. In some embodiments, the person support apparatus acts as a conduit for notification signals of upcoming sounds, receiving and forwarding such notification signals from and to other devices.

A pop sound suppression method, an audio output circuit, and a terminal suppress a pop sound that is generated when an audio output circuit is in an alternating current (AC) coupling structure. The output circuit includes an output power amplifier, a common-mode voltage buffer, a reference voltage generation circuit, a powered-on pop sound suppression switch, and a common-mode switch. The powered-on pop sound suppression switch is configured to control, in a power-on process of the audio output circuit, a voltage level of an output node to be zero. The common-mode switch is configured to control, when a reference voltage level of the reference voltage generation circuit is zero, the voltage level of the output node to be equal to the reference level.

A display panel according to an embodiment of the present disclosure includes a flexible organic electroluminescent panel, and one or a plurality of piezoelectric films provided on a rear surface of the organic electroluminescent panel and vibrating the organic electroluminescent panel as a flat speaker.

A sound producing device (SPD) is provided. The SPD comprises a membrane, having a resonance frequency and a resonance bandwidth; and an actuator, disposed on the membrane, receiving a driving signal corresponding to an input audio signal; wherein the input audio signal has an input audio band which is upper bounded by a maximum frequency; wherein the resonance frequency is higher than the maximum frequency plus a half of the resonance bandwidth.

An order point can be employed in a drive-through or similar setting. The order point can have one or more rotatable menu cases. Each rotatable menu case can include two opposing sides that are equally configured to display a menu. The menu case can be mounted to the order point in a manner that allows either side of the menu case to be rotated into a forward facing position. The menu case can also include angle stops which limit the range of rotation of the menu case and retain the menu case in the forward facing positions. The order point may also include a pivoting canopy which functions to shade the menu cases as well as to prevent damage when a vehicle is too tall.

The instant disclosure provides an LED light, including: a light cap, a hollow heat sink, a drive assembly, a speaker assembly, a light source assembly and a lampshade, wherein the light cap, the hollow heat sink and the lampshade are sequentially connected and form a receiving space, the drive assembly, the speaker assembly and the light source assembly sequentially arranged in the receiving space in the direction of the light cap to the lampshade, and the speaker assembly and the light source assembly are respectively electrically connected with the driving assembly, and the surface of the hollow heat sink provided with multiple holes, and the speaker assembly arranged facing the hole.

A waterproof speaker having a waterproof rating of 8 or more and that is capable of providing a waterproof function at a high water pressure is provided. The waterproof microspeaker includes: a frame comprising a sidewall and a flange portion extending outward from an upper edge of the sidewall; a vibrating portion within the frame; a diaphragm mounted on the flange portion of the frame; and a waterproof ring placed on a sidewall of the frame and configured to protrude further outward than the flange portion of the frame.
