Abstract: A building block includes at least one of a plug portion and a socket portion. The plug portion has two cantilevered tongues deflectable toward each other. Each cantilevered tongue includes a first engaging portion. The socket portion defines a chamber and has two second engaging portions. The plug portion and the socket portion are configured in such a way that the plug portion of one building block is insertable into the chamber of the socket portion of another building block, and the two cantilevered tongues of the building block deflect toward each other after insertion of the plug portion of the building block into the chamber of the socket portion of the other building block, which allows the first engaging portions of the building block to be engaged with the second engaging portions of the other building block, thereby connecting the two building blocks together.

Abstract: A segment display device includes: a housing including an upper, cover and a lower cover connected to the upper cover, the upper cover defining a plurality of upper connection holes and a display window, the lower cover defining a plurality of lower connection holes at positions corresponding to the upper connection holes, the upper connection holes and the lower connection holes being configured for connecting the housing, to a building block, and the housing defining an interlace opening; as circuit board arranged within the housing and including a first circuit port and a second circuit port, the first circuit port and the second circuit port being located at the interface opening; and a segment display arranged on the circuit board at a position corresponding to the display window.

Abstract: A Bluetooth speaker includes an upper case and a lower case. The upper case and the lower case corporately define a receiving space, and the upper case and the lower case each include a mounting portion for connecting with a building block element. A circuit board, a loudspeaker, a Bluetooth module and a light emitting module are received in the receiving space, and the loudspeaker, the Bluetooth module and the light emitting module are electrically connected to the circuit board.

Abstract: A toy assembling apparatus is disclosed. The toy assembling apparatus includes at least one connector, and each connector having at least one of a first connecting portion and a second connecting portion. The first connecting portion includes a connection plate and a connection pillar disposed on the connection plate. The second connecting portion includes a left side board, a right side board, a back side board, a bottom board, and a top board, which jointly form a containing slot for inserting the first connecting portion. The containing slot includes a plate slot for containing the connection plate and a pillar slot for containing the connection pillar. Limit grooves or limit protrudes are formed on the connection pillar. The pillar slot has protrudes or grooves formed thereon correspondingly. The limit grooves match the limit protrudes, such that the first connecting portion matches the second connecting portion of another connector tightly.
