A diaphragm for a micro loudspeaker includes an outer casing that is provided with a through-hole, a membrane that is disposed in the through-hole, and a suspension that connects the membrane and the outer casing. The outer casing is provided with an inner wall that wraps into the through-hole. The suspension includes an effective operation zone that is extended from the inner wall into the through-hole, and a fixed area that is extended from the inner wall to outside the through-hole. The fixed area of the suspension is provided with a cut-off area, which keeps the effective operation zone at a good intactness, and enables the membrane to vibrate up and down more uniformly, thereby improving the sound quality of micro loudspeaker.

The present invention discloses a Fresnel lens with a light receiving effect, including a converging surface and an incidence surface opposite to the converging surface. The incidence surface is provided with an optically effective refractive region and an optically reflective region annularly surrounding the optically effective refractive region. The optically reflective region is provided at least with a prism annularly disposed outside the optically effective refractive region. The prism is provided with a refraction surface which is in adjacent to the optically effective refractive region and a reflection surface which is disposed at a first angle relative to the refraction surface. In addition, a tail end of the prism is an inverted hook part. Therefore, the effective working area of the refraction surface and the reflection surface can be increased, thereby improving the light receiving effect of the Fresnel lens.

A varifocal lens module, consisting of a casing provided with a holding chamber, an opening end, an interconnecting hole, a soft lens disposed on the casing to seal the holding chamber, and a medium control device connects to the interconnecting hole. The soft lens is provided with a first curved surface having a first curvature exposed external of the casing and a second curved surface having a second curvature positioned interior of the holding chamber corresponding to the first curved surface. The medium control device is connected to the interconnecting hole for controlling the volume of the medium inside the holding chamber, whereby the change in volume of the medium changes the compression on the second curved surface, thereby modifying the second curvature of the second curved surface, producing a variation in the spacing between the second curved surface and the first curved surface to achieve a varifocal effect.

An electrical connector assembly includes a first connector and a second connector each defining a mating end of a regular polygon mating with each other. Each regular polygon defines a center, an imaginary circle around the center and a plurality of vertices at the imaginary circle. A plurality of pins are located at the mating ends which composed of one first pin at the center of the first connector, two second pins at least fulfilling with one half of the vertices and arranged at adjacent vertices in turn, one third pin at the center of the second connector and two forth pins at the vertices respectively in a condition that said two forth pins spaced from each other with a largest distance.

Interconnection system incorporated with magnetic arrangement

An electrical card connector includes an insulative housing, a number of contacts and a push-push mechanism. The push-push mechanism includes a slider, an elastic member for driving the slider and a locking arm fixed to the slider. The locking arm includes a hook protruding into a card receiving space for locking with the card when the card is fully inserted into the card receiving space at a card locking position. When the card is ejected under a normal speed, the locking arm can be outwardly deformed to disengage from the card at a card release position. When the card is ejected under an abnormal speed faster than the normal speed, the slider gets over the card release position where the locking arm is restricted by a stop member to prevent the hook from releasing the card.

An electrical connector for connecting a flexible printed circuit board comprises an insulator, a plurality of terminals and an actuator mounting onto the insulator. The insulator comprises a top wall, a bottom wall opposite to the top wall and a pair of side wall joining with the top wall and the bottom wall thereby defining a cavity therebetween. The terminals arranged exposed into the cavity. The actuator can rotate between an opened position where the flexible printed circuit board can be inserted into the cavity and a closed position where the flexible printed circuit board can be abutted against the terminals. A post protrudes from the bottom wall. The actuator defines a locking beam for locking with the post and a through hole for receiving the post when the actuator is located at the closed position.

An electrical card connector (), used for receiving a card () having a cutout (), includes an insulative housing (), a plurality of contacts () retained in the insulative housing, a metal shield () covering the insulative housing to define a card receiving room () and a card inserting port, and an ejector () assembled on the insulative housing. The metal shield includes a main plate () and a pair of vertical walls () extending from the main plate. A ridge () is formed at one of the vertical walls. The ejector includes a slider (), a spring member () and a pin member () for cooperatively guiding/ejecting a card. The slider has a main portion () extending along the card's insertion/ejection direction. The main portion forms a protruding portion () facing toward the card receiving room and a confronting portion () facing toward the one vertical wall. The protruding portion is engaged with the cutout of the card when the card is moved into a locked position in such a manner that the ridge leans against the confronting portion and presses the slider towards the card receiving room.
