Abstract: An inertial sensor and a method therefor. The inertial sensor includes: a first substrate; a medium layer stacked on the first substrate; a first electric-conductive layer stacked on the medium layer, first openings being formed in the first electric-conductive layer and spaced from one another; second electric-conductive layers being bonded to the first electric-conductive layer through bonding structures, a gap being formed between adjacent second electric-conductive layers, which are connected to each other by a connection part, and second openings being formed in each of the second electric-conductive layers and spaced from one another; and a second substrate covering the first substrate, a closed space being formed between the second substrate and the first substrate. Compared with a traditional single-layer structure, the die size is reduced, the manufacturing cost is reduced, and the integration of device into portable consumer applications is improved, and XY axis sensitivity is improved.

Abstract: The present invention provides a speaker module for a mobile terminal provided with a sound output port. The speaker module includes a speaker box. The speaker box includes a first sound output opening and a second sound output opening. A speaker module also includes a first horn barrel and a second horn barrel. The first horn barrel and the second horn barrel are arranged asymmetrically with respect to the speaker box. The speaker module in the present invention realizes the multi-order coupling of the resonance peak, which not only improves the high-frequency performance, but also widens the frequency band range, and at the same time, reduces the manufacturing cost.

Abstract: A method for converting neural network, applied to a terminal device, including: initializing a decision tree, and setting a root of the decision tree; and branching leafs from the root of the decision tree based on effective filters of the neutral network as a decision rule, until all effective filters of the neutral network are covered by the decision tree. The neutral network is a piece-wise linearly activated neutral network. In this method, the neutral network is converted as decision trees and is explained based on the decision trees, so as to solve the black-box problem of the neutral network.

Abstract: Provided is a resonator. The resonator includes: at least one air cavity and a plurality of air passages communicating with the air cavity. The air cavity and the plurality of air passages are tuned to generate one or more acoustic resonances. Therefore, the desired low acoustic damping can be reasonably well maintained, while distributing higher modes over a wider set of frequencies, while also making each of them proportionally weaker. Thus, they may be more easily made weak enough not to interfere with the desired behaviour of the overall acoustic resonator construction.

Abstract: The invention provides a transmission cable with a main baseline layer and a superimposed line layer. The main baseline layer includes a superimposed part, and a non-superimposed part. The superimposed line layer and the superimposed part form an unbendable part; the non-superimposed part forms a bendable par. The main baseline layer includes a first grounding layer, a first base layer stacked, a signal line layer, and a second base layer. The superimposed line layer includes a third base layer and a second grounding layer. The bendable part is small in thickness, so that the transmission cable provided by the invention has good bending performance, thereby improving the practicability of the transmission cable and prolonging the service life of the transmission cable.
