Abstract: A toy block with slot tracks formed thereon takes the form of a hexahedron with six track surfaces. A slot is formed on each of at least one of the track surfaces and has multiple connection ends extending and connecting to different edges of the track surface. Each toy block can at most include six different slots to attain high degree of diversity and variety for playing the toy block. When multiple ones of the toy blocks are assembled, users just need to get the multiple toy blocks to approach each other and the multiple toy blocks can be quickly assembled into a toy block set with high degree of variation and entertaining effect.

Abstract: A wireless headset having ear hook includes a device body, a speaker, an electrical charger, a charger cover, and an ear hook. The speaker is coupled to the device body. The electrical charger is arranged in the device body, and the electrical charger is exposed from the device body. The charger cover is coupled to the device body and selectively covers the electrical charger. The ear hook is integrally formed with the charger cover. By the combination of the ear hook and the electrical cover, the amount of parts is reduced, and when not in use, the headset can be electrically charged by lifting the charger cover.
