Abstract: A speaker includes a telescopic sound chamber, a first diaphragm, and a first piezoelectric vibrating element. The telescopic sound chamber has a box wall, a bottom layer, and a first opening. The telescopic sound chamber includes a plurality of telescopic sub-box layers sleeved on and connected to each other and decreasing in volume layer by layer. The telescopic sound chamber accommodates the smaller telescopic sub-box layer into the larger telescopic sub-box layer to reduce the volume of the telescopic sound chamber. The telescopic sound chamber moves the smaller telescopic sub-box layer away from the larger telescopic sub-box layer to increase the volume of the telescopic sound chamber. The first diaphragm is arranged on the box wall to cover the first opening. The speaker can improve the drawbacks of low-frequency range distortion and has the advantages of full audio, high volume, and smooth sound pressure.

Abstract: An audio decoding method performed by a computer device includes obtaining encoding vectors of audio frames in an audio frame sequence, and performing, in response to a current audio frame in the audio frame sequence being to be decoded, up-sampling on an encoding vector of a historical audio frame to obtain an up-sampling feature value describing the historical audio frame. The historical audio frame includes one or more audio frames decoded before the current audio frame in the audio frame sequence. The method further includes performing, based on the up-sampling feature value, up-sampling on an encoding vector of the current audio frame to obtain decoded data of the current audio frame.

Abstract: A cracking process for a reaction distillation of chlorosilane slurry includes feeding a chlorosilane slurry into a phase separator, drying a solid phase, feeding a chlorosilane polymer into a plate distillation column, returning kettle materials of the plate distillation column, and dividing a material produced from a top of the column. The process adopts an ionic liquid catalyst, which is environmentally friendly and reusable. The cracking and distillation of chlorosilane polymer are carried out simultaneously to shorten the time and increase the utilization rate of raw materials, which can reduce energy consumption and save costs and facilitate industrial production. A plate column is used as a distillation column, in which the two phases of the gas and liquid are sufficiently contacted. Therefore, the transfer of mass and heat is good, the production capacity is good, and the tower is not easily blocked, thereby making it easy to clean.

Abstract: Disclosed are a separator membrane, a separator membrane roll, a battery cell, and a power lithium battery. The separator membrane includes a porous base film and a bonding layer; in a preset direction of the porous base film, the surface of the porous substrate includes a middle blank area, and a coated area at the two ends; the bonding layer is applied on the two coated areas. By means of applying the bonding layer to both ends of the porous base film surface, it is possible, during the process of assembling and forming the lithium battery cell, to cause the bonding layer to contact and bond with the two ends of the negative electrode inside the lithium battery cell, effectively ensuring that the lithium battery bears sufficient tension, pressure, and vibration during assembly, vibration testing, and long-term cycling.
