摘要： A head-mountable frame includes a frame body configured with an arcuate shape, and a pair of ear shells connected to both ends of the frame body, respectively. Each of the ear shells is provided with a receiving cavity for installing an earpiece module. The head-mountable frame includes an earmuff assembly provided on the inner side of each ear shell and configured to fit closely to an ear, thereby forming a closed sound transmission cavity between the earpiece module and the ear. The receiving cavity of the ear shell is configured to receive the earpiece module through press-in fit removably. A head-mountable Bluetooth headphone includes the head-mountable frame and a Bluetooth headphone module which can be removably mounted in the receiving cavity through a press-in fit. A helmet includes a helmet body and a Bluetooth headphone module which can be removably mounted in the helmet body.

摘要： A dynamic display apparatus is provided, including a simulation unit and a control unit. The simulation unit comprises a plurality of light-emitting elements (e.g. light-emitting diode beads) that are spatially arranged on a platform (e.g. flexible circuit board) to form one or more simulated moving tracks of one or more objects to be simulated. The control unit is communicatively coupled to the light-emitting elements, and controls an ON/OFF state, an ON/OFF frequency, an ON/OFF duration, and/or a light intensity of each light-emitting element such that lights emitted therefrom compositely mimic at least one motion state of the objects. The dynamic display apparatus can be used to mimically display complex effects, such as the flying and flashing effects of fireflies.
