An open-type magnetic circuitry of loudspeaker includes a lower yoke having a central portion upward projected to form a bobbin, a magnet positioned on top of the bobbin, a voice coil wound around the bobbin and the magnet, and a diaphragm connected at a root portion to the voice coil. The magnetic circuitry of loudspeaker is characterized in that the lower yoke is provided at an upper side surrounding the bobbin with a plurality of radially equally spaced supporting posts, a top end of which being higher than at least a bottom side of the magnet, and that a ring-shaped upper yoke having a central hole is covered onto the top end of the supporting posts, such that heat produced by the voice coil during working could quickly dissipate via the spaces among the supporting posts. Since no heat would accumulate in the loudspeaker, the loudspeaker could always maintain good sound quality.

An electrostatic discharge (ESD) protection device includes a drain region and a source region, each having a heavily-doped region and a lightly-doped region, wherein the junction depth of the lightly-doped region is deeper than that of the heavily doped region. Accordingly, the ESD current density will be decreased owing to the enlarged junction area during the ESD event. In addition, the heat dissipation can be spread over the enlarged junction area instead of being focused on the drain cylindrical edge. Moreover, low parasitic capacitance in the bond pad is achieved because the junction capacitance of the lightly-doped region is smaller than that of the heavily-doped region. Furthermore, conducting blocks are arranged between the lightly-doped regions and the source/drain electrodes, respectively, to prevent the metal melt filament from spiking the junction.

Electrostatic discharge protection device and its method of fabrication

A buffering pad for device packages is provided. The buffering pad is composed of a main member, a pair of lateral supporting members, and at least one protection member. The main member and the lateral supporting members are each formed by folding an integral piece of cardboard. At least one buckling piece is integrally formed either on the main member or on the lateral supporting member for fastening the protection member to the main member. Alternatively, a supporting glove is used to fasten the protection member to the main member. The protection member is a substantially U-shaped block which provides support and enforcement to the portion where it is fastened to.

A vertical pushing device for a perfume sprayer having a base member, a motor connected to the base member, an eccentric gear linked to the motor, a sliding block connected to a guide rail to the base, a switch member connected to the motor and interactive with a movement of a push board of the sliding block, and a controller for actuating the motor in response to signals from the switch. The push board of the sliding block contacts the nozzle of the perfume cannister so as to dispense perfume relative to a movement of the sliding block. The sliding block has a long hole which receives the eccentric gear therein.
