An inflatable speaker includes a collapsible inflatable housing and a loudspeaker, the collapsible housing includes a circumferential side wall, a first end wall, a second end wall, and a valve for inflating the collapsible inflatable housing, wherein the first end wall includes a first inner layer, a first outer layer, and a speaker support plate between them provided with an audio transmission inner sound hole, the first outer layer is provided with an outer sound hole. The loudspeaker is positioned between the first inner layer and speaker support plate, a waterproof ventilated acoustic membrane is placed to cover the loudspeaker frame, a first waterproof adhesive permanently binds the waterproof ventilated acoustic membrane and speaker support plate together, and a second waterproof adhesive permanently binds the edge portion of the outer sound hole and speaker support plate together, thus, giving the inflatable speaker a higher level of protection.

A play structure is formed from flexible struts supporting a fabric. The struts are inserted through pockets along the edges of the fabric. The struts are joined together by connectors at apexes of the structure. The struts form an upper frame and a lower frame. The upper and lower frames are connected by battens. The struts and battens hold the fabric in a selected shape, such as a sailboat. The battens are formed from flat, flexible members that are bent about their longitudinal axis to form a C-shaped cross section. Ends of the battens are inserted into curved batten receivers on the connectors. When a downward force is applied, the upper frame is pressed toward the lower frame. The battens bend and flatten to resiliently allow the structure to collapse. When the force is relieved, the battens resiliently resume their curved shape, restoring the structure to its original configuration.

An aquatic toy that is a biomimetic fish with a watertight body portion. The body portion contains a battery electrically connected via a controller to at least one coil. The coil is positioned relative to a magnet and the coil can be caused to oscillate by virtue of a controller defined alternating current passing through the coil. The oscillation of the coil causes movement of a tail fin that is engaged to said watertight body to cause the fish to move forward through a body of water.

A method for displaying information of a physical game participant includes obtaining information of the physical game participant and controlling an LED light-emitting device to generate a corresponding lighting form based on the information.

In one embodiment there is provided an aquatic toy configured for movement under water. The aquatic toy employs sensors to automatically turn on when placed in water and further employs a timing circuit to automatically turn the toy off after a predetermined amount of time. The aquatic toy further includes a shock sensor to monitor movement of the toy when in water and after the timer expires. Movement such as tapping on the tank, splashing the water, or physical movement of the toy will turn on the toy and re-activate the timer. However, the sensors can further detect when the toy is dry to ensure the shock sensor is only active when the sensor is wet.

A diving toy, or dive stick, that is connectable and extendable. The diving toy includes connectable and/or extendable portions that enables the length of the diving toy to be changed and enable it to be converted into a dive-ring, extended dive stick, larger dive-ring, dive-chain, or a multitude of other amusing shapes. In various games of play, one or more diving toys is thrown into a pool. A player retrieves the diving toy from the bottom of the pool or plays various games of play with the diving toy while submerged underwater.

A vibration-powered device adapted for flotation and propulsion on an upper surface in a liquid. The device having a body with a top side adapted to be at least partially disposed above the surface of the liquid, and a bottom side adapted to be at least partially submerged below the surface of the liquid. A vibration mechanism is disposed in the body. A propulsion fin is connected to the body. The fin includes a top side adapted to be disposed at least partially above the liquid surface, a bottom side adapted to be disposed at least partially below the surface. The vibration mechanism is adapted to oscillate the free distal end of the propulsion fin upward and downward.
