A packaged piezoelectric exciter module comprises an insulating bracket, a positive conductive portion, a negative conductive portion and at least one exciter plate. The positive and negative conductive portions and the exciter plate are packed within the insulating bracket. The exciter plate is a laminated plate having a metal layer between two piezoelectric layers. The metal layer has at least one boundary portion so that the thereof uncovered by the piezoelectric layers. The piezoelectric layers are connected to the positive conductive portion, and the boundary portion is connected to the negative conductive portion. The positive and negative conductive portions each have at least one connecting pin extended out of the insulating bracket. Thereby, the positive and negative conductive portions and the exciter plates are packaged as a module for being connected to an electric connector or attached to a circuit board.

A controller for detection of touches by a single finger or multiple fingers on a touch panel, the touch panel including a first group of electrodes arranged in a first direction and a second group of electrodes arranged in a second direction, thereby forming a plurality of crossover points. The controller includes: a plurality of signal drivers coupled to the first group of electrodes and configured to excite the first group of electrodes sequentially using a spread spectrum signal; a plurality of signal sensors coupled to the second group of electrodes and configured to detect peaks and troughs of capacitive coupled signals at the second group of electrodes, the detecting being performed simultaneously for the crossover points along a current one of the first group of electrodes that is being excited; and a signal processing device configured to detect the touches on the touch panel and to determine touch positions and touch movements, based on the detected peaks and troughs of the capacitive coupled signals.

An electrical connector (100) includes an insulative housing (1), a number of contacts (2), a shield (3) and a camera module (4). The insulative housing has a number of passageways (12) defined therein. The contacts are correspondingly received in the passageways. Each contact includes a holding portion (24) engaging with the passageway and securing the contact with the housing, a soldering portion (26) soldering to a Printed Circuit Board, and a contacting portion (23) electrically connecting the camera module. The camera module mounts on the insulative housing, and have a number of contacting sections (430). The camera module also defines a number of hook engaging portions (44), and a projecting portion (420). The shield has a number of hooking portions (35) corresponding to the hook engaging portions and a cutout (37) engaging with the projecting portion. The shield surfacely and peripherally surrounds the camera module.

The present invention provides a colored gold-wrapped thread and a method for making a gold-plated embroidery by using the same, thereby solving the technical problem of single color of a gold-plated embroidery. The method for making a gold-plated embroidery includes preparing embroidery threads, preparing colored gold-wrapped threads and colored gold fixing threads in a mode of one-to-one correspondence of the same color, preparing an embroidery backing material, arranging a to-be-embroidered pattern on the embroidery backing material, preparing embroidery tools, arranging the embroidery backing material on a reel, and embroidering a pattern. The colored gold-wrapped thread includes a thread skin and a wrapped core, where the thread skin is made of a colored glittering silk material having metal luster, and the wrapped core is made of rayon having no twisting strength or a soft and smooth cotton thread.

A conductive stub of a sound exciter comprises an insulating stub and at least two beams. Each beam has a positive electrode surface and a negative electrode surface. The stub is connected with a positive electrode lead and a negative electrode lead serves for being connected to an external sound source. A positive electrode conductive element and a negative electrode conductive element are embedded in the stub. Each of the positive electrode conductive element and the negative electrode conductive element has an external joint for connecting touch press ends. The touch press ends of the positive and negative electrode conductive elements are in contact with a positive and a negative electrode surface, respectively, of each beam. By above mentioned components, sound signals are transferred to each beam to excite the beams to oscillate and then emits sound.

A piezoelectric ceramic composition includes a top-layer, a bottom-layer and at least one intermediate-layer ceramic sheets stacked to each other for sintering. An alloy layer of silver and palladium is interposed between every two ceramic sheets, and a sliver layer is coated on each exposed surface of the top-layer and the bottom-layer ceramic sheets, so as to form a positive and a negative electrode circuit therein. The piezoelectric ceramic composition with the silver layer is attached to at least one surface of a metal plate to make a piezoelectric element which is used to make a piezoelectric actuator, loudspeaker or buzzer.
