Abstract:
A fluid transfer guiding/controlling device and an application system thereof. The guiding/controlling device is composed of a power transfer/distribution unit and a switch member. The power transfer/distribution unit has a first chamber and a second chamber. At least one bypass flow ways are disposed in the first chamber. Stop sections are disposed in the second chamber. Communication notches are disposed in adjacency to the stop sections in communication with an outer side. The switch member having an internal flow guide passage and a first flow guide window and a second flow guide window is disposed in the first and second chambers. The first flow guide window is switchable between the bypass flow ways. The second flow guide window is moved from the stop section to pass through a corresponding communication notch, whereby part of the fluid in the flow guide passage flows through the communication notch.
Abstract:
A speaker includes a frame, a diaphragm, a cover, a magnetic device, and a voice coil. The cover and the diaphragm are both disposed on a first side of the frame, and the cover covers the diaphragm. The magnet device is disposed on a second side of the frame. The voice coil is disposed on the magnetic loop generated by the magnetic device and integrated with the diaphragm. The magnetic device includes a yoke, a magnet, and a pole piece. The yoke includes a protrusion by bending for the magnet and the pole piece to be mounted upon.
Abstract:
An electrical connector is disclosed, which is configured with an insulating frame for carrying a speaker while arranging terminals at two sides of the insulating frame. Each of the terminals further comprises a vertical-extending fixing part for holding securely on the insulating frame, and a movable part connected to the fixing part while parallel-extending from the same. With the aforesaid structure, as the terminals only occupy a small space available on the insulating frame comparing with those conventional connectors, the electrical connector of the invention is able to carry a speaker with larger magnet so that the aforesaid electrical connector is preferred as it can, in a way, enhance the electrical performance of the speaker.
Abstract:
An electrical-acoustic transducer includes a housing, a magnetic circuit device, a voice coil and a diaphragm. The magnetic circuit device is disposed in the housing and generates a magnetic circuit. The voice coil is disposed on the path of the magnetic circuit, and configured for generating magnetism upon receiving an electrical power. The diaphragm is made of metal, fixedly combined with the voice coil and having a scraggy cross section. When the voice coil of the electrical-acoustic transducer generates the magnetism according to the electrical power and interacts with the magnetic circuit, the diaphragm vibrates so as to generate sound.
Abstract:
A speaker includes a yoke, a diaphragm, an electrode plate, a magnet and a lower plate. The yoke includes a base, a wall and a terminal plate connected integrally to each other. The wall has a chamber and is mounted on the base. The rest components are mounted in the chamber. An amount of the components of the speaker is reduced because of the integral connection among the base and the wall. Consequently, the manufacturing costs and assembly process will be lowered and simplified.
Abstract:
A pump with variable suction/discharge amount and a transmission drive device and a driving method thereof. The pump is a rotary vane pump having a vane chamber body. The vane chamber body is composed of a fixed wall member, a movable wall member, a movable vane chamber sleeve and a vane rotor. The vane chamber is extendable/retractable in an axial direction of the vane rotor. At least two pumps are assembled in communication with each other to form a closed loop for the active pump to drive the passive pump. In operation, passive the vane chambers of the active pump and the passive pump are automatically extended/retracted and modulated until the driving force and the load resistance achieve a balanced state passive, the vane chambers and the rotational speeds of the active pump and the passive pump are automatically adjusted to be in inverse proportion to each other.

Abstract:
A light-emitting diode includes an optical layer formed in an array of substantially equidistant light extracting spots integrated to its multi-layered structure. The array of light extracting spots includes a distribution of juxtaposed hexagon patterns. The layer thickness of the light extracting spots is less than 800 Å.
Abstract:
A power-tolerant assembly for combining a sound ring and a diaphragm of a speaker comprises a disk frame having a magnetic inducing body; a vibration diaphragm installed upon the disk frame; the vibration diaphragm having an annular lower ring section; a distal end of the annular lower ring section being bent as an L shape or U shape; and a sound ring within the vibration diaphragm; the magnetic inducing body being located below the sound ring; two sides or three sides of the sound ring being combined to the L or U shape distal end for increasing the combining area and strength of the combination of the adhering portion and the sound ring. Or a dust-proof cover is installed upon an upper side of the sound ring; the vibration diaphragm having an annular lower side; a lower distal end of the annular lower end being bent so as to enclose the sound ring.
