    摘要： A miniature speaker includes a frame having a base plate, a cover plate covering the frame and forming an accommodating space; a vibrating system fixed on the frame; and a magnetic circuit system for driving the vibrating system to vibrate. The magnetic circuit system includes a main magnet, a first pole plate attached to the main magnet, and two first side magnet components. Each of the first side magnet components includes a first side magnet, a second pole plate and a second side magnet stacked sequentially from the base plate along a direction toward the cover plate. A magnetizing direction of the first side magnet is opposite to that of the main magnet, and a magnetizing direction of the second side magnet is opposite to that of the first side magnet.

    摘要： A method and a device for scheduling true CPU resources for a virtual machine system are disclosed. In one aspect a virtual machine monitor (VMM) acquires information about loads on virtual CPUs (VCPUs), and the VMM assigns the true CPU resources based on the information about the loads on the VCPUs in such a manner that more true CPU resources are assigned to a VCPU with a higher load. With the method and device according to certain embodiments, it is possible to assign the true CPU resources based on the information about the loads on the VCPUs in such a manner that more true CPU resources are assigned to a VCPU with a higher load. Further, certain embodiments are implemented directly by the VMM irrespective of types of upper-level GOSs, and thus is versatile.

    摘要： It is well known that relay-based DF cooperative wireless networks outperform AF cooperative networks. However, this performance enhancement is achievable through considerable signal processing (precoding/decoding) at relay nodes. To reduce the precoding/decoding complexity, a method for precoding and decoding a distributive MIMO channel in the relay-based DF cooperative wireless network using EVD based on properties of Jacket transformations is provided.
