20120106775 | SPEAKER - A speaker includes a base defining a pair of receiving cavities separated from each other in a longitudinal direction and an engaging portion disposed between the pair of receiving cavities, a pair of magnetic circuit systems received into the pair of the receiving cavities, a diaphragm attached on the base, a pair of voice coil members connecting with the diaphragm, and a suspension mounted on the base. The suspension defines a pair of separating portions separated from each other in a lateral direction. Each separating portion defines a fixing portion engaging with the engaging portion of the base, a pair of connecting portions extending from two ends of the fixing portion and towards the diaphragm, and a pair of supporting portions connecting with the connecting portion for engaging with the pair of voice coil members, respectively. | 05-03-2012 |
20120119716 | POWER SUPPLY CIRCUIT - A power supply circuit is disclosed in embodiments of the present invention, which includes: a voltage output device, configured to generate an output voltage; a parasitic resistance, connected between an output end of the voltage output device and an external load, where two ends of the parasitic resistance generate a voltage drop; and a compensation circuit, connected to the output end of the voltage output device and configured to generate a compensation voltage, where the compensation voltage is loaded onto the voltage output device, so as to offset the voltage drop generated by the parasitic resistance, so that a voltage obtained at an input end of the load is roughly equal to the output voltage generated by the voltage output device. The circuit is applicable to improving load regulation of a power supply. | 05-17-2012 |
20120177244 | SPEAKER - A speaker includes a holder forming a hollow space, a magnetic system received in the hollow space, a suspension assembled with the holder and defining a supporting portion, a pair of fixing portions far away from the supporting portion and fixed on the holder, and a plurality of arm portions connecting the supporting portion and the fixing portions, respectively. The arm portions defines a pair of outer arm portions protruded outwardly from the circumference of two ends of the supporting portion and a pair of inner arm portions extending from the circumference of said two ends of the supporting portion and set in space with respect to the inner arm portions, respectively. | 07-12-2012 |
20130141006 | Constant Current DC-DC Converter - A device includes a positive power supply voltage node; and a first operational amplifier including a first input, a second input, and an output coupled to the second input.

The upload interface, the network interface and the download interface are displayed and update in real time. | 11-13-2014 |
20150016657 | VIBRATING DIAPHRAGM AND SOUNDER USING THE SAME - A diaphragm and a sounder using the same are disclosed in the present disclosure. The diaphragm includes a suspension portion and a dome assembled with the suspension portion. The dome includes a polyethylene terephthalate (PET) layer, a middle layer and an adhesive layer, with the middle layer sandwiched between the PET layer and the adhesive layer. The middle layer is formed with a first through hole for adjusting the deformation amount of the diaphragm. The present disclosure can improve the flatness of the dome and prevent deformation of the dome after the vibration. | 01-15-2015 |
20150110336 | Speaker Box - A speaker box is disclosed. The speaker box includes a housing and a speaker unit. The housing includes a bottom, a side connected with the bottom, and a rear volume formed by the side and the bottom, the side including a first side and a second side connecting with the first side. The speaker unit includes a frame, a magnetic circuit unit accommodated in the frame, a vibration unit positioned above the magnetic circuit unit and fixed to the frame, and a front volume. The frame includes a first sidewall abutting against the first side, and a second sidewall connecting with the first sidewall. The first side includes a first mounting portion, the first sidewall includes a second mounting portion engaging with the first mounting portion. | 04-23-2015 |
20150116352 | GROUPS CONTROL METHOD, SYSTEM FOR A DYNAMIC MAP-TYPE GRAPHIC INTERFACE AND ELECTRONIC DEVICE USING THE SAME - A dynamic map-type graphic interface includes a number of user interface (UI) components.
