Abstract: An electrode assembly and a lithium ion electric roll having the same are provided. The electrode assembly includes: a first electrode unit; a first anti-puncture cushion; in which the first electrode unit includes a first electrode sheet, an second electrode sheet, and a separator, the second electrode sheet comprises a second top edge and a second bottom edge along the length direction of the first electrode unit; an edge of the first anti-puncture cushion exceeds the second electrode sheet from the second top edge or the second bottom edge along the length direction of the first electrode unit.

Abstract: An air-ground joint trajectory planning and offloading scheduling method and system for distributed multiple objectives is provided. At the beginning of each timeslot, an unmanned aerial vehicle (UAV) selects a flight direction based on a total energy consumption of all devices and a total amount of unprocessed data of all the devices in the current system, and flies a fixed distance towards a certain direction. Before the UAV reaches a new location, each terrestrial user independently selects a task data offloading scheduling strategy based on the total energy consumption of all the devices and the total amount of the unprocessed data of all the devices in the current system. In order to improve an expected long-term average energy efficiency and data processing capability, the present disclosure also provides average feedbacks for an energy consumption and unprocessed data.

Abstract: An energy Internet system, an energy routing conversion device, and an energy control method, relating to a field of energy information. An alternating-current (AC) side energy routing conversion device of the energy Internet system includes a plurality of first route ports, and a direct-current (DC) side energy routing conversion device includes a plurality of second route ports, where each second route port is connected to a corresponding first route port by means of a corresponding DC busbar. A plurality of energy devices are connected to a DC busbar by means of corresponding first AC/DC converters or first DC converters. The AC side energy routing conversion device and the DC side energy routing conversion device collect energy information of the energy devices and adjust energy of the energy devices on a basis of energy balance constraint conditions.

Abstract: Disclosed is a micro loudspeaker, which comprises a magnetic circuit system, a vibration system and a support system. The magnetic circuit system comprises a yoke, and a magnet and a washer accommodated within the yoke. The vibration system comprises a diaphragm and a voice coil adhesively fixed to the diaphragm. The support system comprises a front cover, and a housing matched and combined with the front cover. The housing comprises a bottom wall and a side wall. The bottom wall is provided with a mounting portion accommodating the magnetic circuit system, and is also provided with an assembly plane for assembly with a terminal. A height difference is provided between a position of the bottom wall of the housing corresponding to the assembly plane and a position of the side wall of the housing corresponding to the assembly plane, so as to cooperatively form an avoidance inclined surface.

Abstract: A loudspeaker module emitting sound at a lateral side comprises a loudspeaker unit and a module housing comprising a lower module housing, a middle module housing and an upper module housing. A space formed by the loudspeaker unit, the middle module housing and the lower module housing is a rear sound cavity. A space formed by the loudspeaker unit, the middle module housing and the upper module housing is a front sound cavity. The loudspeaker module further comprises a cover plate which forms a cavity together with the upper module housing. The cavity is communicated with the rear sound cavity through a conducting hole. By utilizing the loudspeaker module of the present invention, superfluous space of the upper module housing can be converted into the rear sound cavity, and therefore the size of the rear sound cavity is increased, and the acoustic performance of the loudspeaker module is improved.

Abstract: The present invention discloses a speaker structure, including a vibration assembly, a magnetic circuit system, a speaker housing and shields, wherein the speaker housing is configured to carry the vibration assembly and the magnetic circuit system; the shields are disposed on the speaker housing; the shields are made of a magnetically conductive material to form a magnetic shield surrounding the speaker structure; and the shield may be embedded inside the speaker housing and/or mounted on an outer surface of the speaker housing. The speaker structure provided by the present invention can effectively prevent a magnetic flux leakage phenomenon without affecting its sound performance; and meanwhile, the shields do not additionally occupy a space inside an electronic device where it is mounted.
