The present invention provides a device and method for diagnosing an audio circuitry, which is applied to a mobile terminal and its earphone. Both of the mobile terminal and its earphone include: a MIC circuit and a sounding circuit, wherein, this device includes: a MIC Circuit Diagnosis Module and a Sounding Circuit Diagnosis Module; A MIC Circuit Diagnosis Module is used for obtaining an amplitude and frequency of a sine wave signal sampled by the MIC circuit, determining whether the MIC circuit is qualified or not according to the amplitude and frequency and outputting the sine wave signal. A Sounding Circuit Diagnosis Module includes: a converter plate with a MIC circuit and a processor; the converter plate is used for sampling an analog signal output by the sounding circuit, converting the analog signal into a digital signal and sending it to a processor; and the processor is used for analyzing and processing the amplitude and frequency of the digital signal and determining whether the sounding circuit is qualified or not. According to the technical scheme provided by the present invention, the quality problem existing in the audio circuitry module of the mobile terminal can be solved, so as to reduce users' complaints and improve the customer satisfaction.

Device and method for diagnosing audio circuitry

A camera socket () includes a metallic housing () defining a receiving space (), a contact terminal insert disposed within the metallic housing () and including a plurality of contact terminals () integrally formed with an insulative housing () and arranged in an array. Each contact terminal () includes a fold-back contact engaging arm () extending backwardly and offset from a main portion () of the contact terminal () in a way such that a free end () of each of the contact engaging arm is located adjacent to a sidewall () of the metallic housing () for engaging with a camera module ().

An electrical connector includes an insulative housing (), a number of terminals () received in the housing and a shell () covering the housing thereby forming a receiving space (). The insulative housing () defines a base portion (), a tongue portion () extending frontward from the base portion and having numbers of passageways () receiving the terminals and extending through the base portion. The shell () include a pair of pressing portions () extending to the receiving space and pressing against said tongue portion () in a direction perpendicular to the tongue portion.

An electrical connector includes an insulating housing having sidewalls and end walls for defining a receiving groove, a number of contacts retained in the insulating housing, the contact including a mating beam extending into the receiving groove and a retaining beam retained in the sidewall. The contact further includes a tail portion extending out of the insulating housing from the retaining beam and a soldering portion formed on a tip end of the tail portion. The soldering portion is located between a highest point and a lowest point of the contact so that the height of the electrical connector upon a PCB can be reduced, which can also reduce the mating-height of the electrical connector after mating with a mating connector.

An electrical card connector () includes an insulating housing (), a metal shield () defining a plurality of channels (), a terminal module () with a plurality of contacts () received therein and a clip. The metal shield shields over the insulating housing for defining a card receiving space. The clip includes a pair of first elastic pieces () and a second elastic piece (). The first elastic piece forms a first contact portion () and a second contact portion (). The first contact portion protrudes into the card receiving space for connecting with an inserted card (). The second elastic piece forms a flexible arm () interfering with the second contact portion.
