    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.
