After a first electronic device establishes a first connection to a second electronic device, a mouse pointer of the first electronic device may cross a boundary of a display interface and appear in a display interface of the second electronic device. When the mouse pointer is displayed on a display of the second electronic device, each time a user performs an input operation by using an input device, such as a mouse or a keyboard, of the first electronic device, the second electronic device may receive an input event from the first electronic device, and make a corresponding response to the input event. At the same time, the input event on the first electronic device side is shielded.

The present disclosure provides an underwater speaker. The underwater speaker includes an outer shell, with a circuit board arranged inside, a speaker, and a lampshade with a first opening at the top. The speaker is electrically connected to the circuit board. The luminescent body is arranged on the circuit board. The luminescent body is oriented towards the interior of the lampshade, and a graphic mapping unit is formed on the lampshade. This embodiment uses the speaker to play audio and achieve the function of an underwater speaker. When the luminescent body emits light, the light can be mapped onto the water. This improves the multiplicity and effect of light and shadow, and meets users' needs for complex and multi-element light and shadow effects.

A three-dimensional thermoelectric energy harvester and a fabrication method thereof. Low-resistivity silicon is etched to form a plurality of grooves and silicon columns between the grooves, and an insulating layer is formed on a surface of the groove, and thermoelectric columns are fabricated by using a thin-film deposition technique, so that the thermoelectric column and a neighboring silicon column form a thermocouple pair; and then, a metal wiring is fabricated by processes such as etching and deposition, followed by thinning of the substrate and bonding of the supporting substrates, thereby completing fabrication of the three-dimensional thermoelectric energy harvester. Fabrication of the thermocouple pair structure by one thin-film deposition process simplifies the fabrication process. The thermocouple pair using silicon ensures a high Seebeck coefficient. The use of vertical thermocouple pairs having a column structure improves the mechanical stability of the thermoelectric energy harvester.

A bandwidth configuration method includes: A terminal acquires that a narrow bandwidth mode is used at a network side by a downlink transmission signal and/or an uplink transmission signal; and the terminal configures a receiving bandwidth and/or a transmitting bandwidth, where the receiving bandwidth and/or the transmitting bandwidth corresponds to the narrow bandwidth mode at the network side. The terminal side can acquire whether the network side uses the narrow bandwidth technology, and automatically adjust a bandwidth of a corresponding channel at the terminal side when the network side uses the narrow bandwidth technology, so that intra-system performance loss and inter-system interference that are caused by different bandwidth modes between the terminal side and the network side are avoided, thus improving performance of a communication system.
