Abstract: A warning device for a container includes a photo-audio drive circuit including a photo-audio IC (integrated circuit), at least one light emitting member connected to the photo-audio IC, a loudspeaker connected to the photo-audio IC, and two exposed metallic contacts each connected to the photo-audio IC. Thus, the warning device provides a photo-audio effect to notify a user that the container is waterless or the water level of the container is under a determined height, so that the user can replenish the water of the container.

Abstract: A container includes a photo-audio drive circuit including a photo-audio IC (integrated circuit), at least one light emitting member connected to the photo-audio IC, a loudspeaker connected to the photo-audio IC, and two exposed connecting legs each connected to the photo-audio IC. Thus, the two exposed connecting legs are electrically connected with each other when contacting liquid to conduct the photo-audio drive circuit to form a circuit, so that the photo-audio IC drives the light emitting member to light and drives the loudspeaker to emit sound.

Abstract: An ornament includes a main body, and at least one light emitting device. The light emitting device includes a transparent cover mounted on the main body, a circuit board mounted in the transparent cover and having two connecting legs each exposed outward from the cover, and a light emitting member mounted on and connected to the circuit board. Thus, when the two connecting legs of the circuit board contact liquid, the circuit board and the light emitting member are connected and conducted, so that the light emitting member can emit blinking light outward from the cover.

Abstract: A light emitting device includes a housing, a circuit board and a base. The circuit board is hidden in the base with lower end of two conductive wires thereof sticking out from the bottom of the base. A battery, and a lamp are fitted onto the circuit board. The housing is made of materials that allow light to pass through, and has blocks of ornamental objects received in it. The base is closely fitted into a lower opening of the housing with the lower end of the conductive wires facing outwards. When the light emitting device is put into a conductive drink, the drink will get into contact with the lower ends of the conductive wires so as to complete the circuit for the lamps to send out light through the housing.

Abstract: A drinking vessel capable of emitting light and sound includes a main containing body, a base sealing a lower opening of the containing body, a circuit board received in the base, and a mercury vibrating switch electrically connected to the circuit board. The circuit board has several LEDs, and a musical IC fitted thereto. When the main containing body is tilted, the mercury vibrating switch will complete the circuit for the LEDs and the musical IC to send out light, and music respectively.

Abstract: A container with sound and light emitting function includes a containing body, a handle attached to the containing body and an electric circuit. The electric circuit includes speakers, light emitting equipments, two projecting contacts and an IC. The light emitting equipments are attached to outer side of the containing body. The projecting contacts pass through a respective through hole of the containing body into the inner space of the containing body so that same can get into contact with each other electrically to complete the electric circuit for the IC to activate the speakers and the light emitting equipments to send out sound and light when drinks are poured into the containing body to submerge both of the projecting contacts.

Abstract: An antiskid member of a cooling mug is attached to a bottom side of the cooling mug. The antiskid member can be secured in a circular locating protrusion on the cooling mug bottom side. The antiskid member can also be attached to the bottom side by means of glue or an injection molding machine, which directly forms the antiskid member on the bottom side.
