An earphone includes a basket defining a through hole. A leading wire board fixed underneath the basket has a pair of solder foils on a bottom surface thereof. A magnet unit is located in the basket with the through hole adjacent to a side edge of the magnet unit. A diaphragm is arranged on the basket and over the magnet unit. A voice coil is fixed to a bottom of the diaphragm and surrounding the magnet unit. The voice coil has two leading wires. Each leading wire passes through the through hole of the basket and further bends to solder with the corresponding solder foils of the leading wire board.

A probe connector includes an insulating housing defining inserting passages each longitudinally penetrating therethrough with a blocking rib being protruded in a periphery inside thereof. A probe has a base board of which a front end has a contact head stretched forward out of the inserting passage, and a rear end has a resisting board extending downward from an end edge thereof and two blocking boards protruded downward from two side edges thereof for cooperating with the blocking rib to prevent the probe from sliding out of the inserting passage. A terminal has a base plate blocking a rear end of the inserting passage, and an elastic arm extending forward from a top of the base plate with a free end designed as a contact portion abutting against the base board. An elastic element is retractably located between the resisting board and the base plate.

A phase-locked loop (PLL) with novel phase detection mechanism is provided, including a phase frequency detector (PFD), a controller, a digital-to-analog (D2A) module, and a voltage-controlled oscillator/current-controlled oscillator (VCO/ICO), wherein PFD has a reference signal input and an input from the output signal of the VCO/ICO and is connected to the controller, the controller is then further connected to the D2A module, the D2A module converts the control signal from the controller into an analog voltage to control the frequency and phase of VCO/ICO. It is worth noting that the PFD of the present invention has a novel phase detection mechanism so that the phase detection can be accomplished by observing signal level transitions of the reference signal input and a delayed reference signal with respect to the output signal of the VCO/ICO without edge alignment. In addition, the novel phase detection mechanism also allows flexible reference signal input.

A connector assembly includes a printed circuit board defining an inserting window and soldering holes adjacent to two sides of the inserting window, and an electrical connector assembled in the inserting window. The electrical connector includes an insulating body, terminals disposed in the insulating body and each having a soldering arm levelly extending rearward to stretch behind the insulating body, and a shell enclosing the insulating body and the terminals. Each side board of the shell has a substantial middle punched outward to form a soldering board extending levelly, and a lower part of a rear edge punched outward and then bent downward to form a soldering tail inserted downward in the soldering hole of the printed circuit board. The soldering boards of the shell and the soldering arms of the terminals are flush with one another to be levelly against and further soldered onto the printed circuit board.

A network reputation system and its controlling method are provided. A credential and exchange component permits a user to generate credentials and exchange matching items with those persons having a social relationship with the user. A reputation evaluation component enables other users to make evaluations about an estimatee via the sharing of social network information. A query and response component receives a query from a person having a social relationship with the user for requesting an evaluation about the estimatee, and responds with an associated evaluation result to the person having a social relationship with the user, via the sharing of social network information and the evaluations made by the other users about the estimatee.
