Abstract: A speaker apparatus capable of operating in a large amplitude regime by minimizing magnetic loss, is provided. The speaker device includes a magnet configured to generate a magnetic flux, a pole piece configured to form a path of the magnetic flux generated by the magnet, a back plate provided at a lower end of the pole piece to support the magnet, and a plate provided to form a magnetic gap between the plate and the pole piece. Several plates may be provided so that the magnetic gap is expanded to enlarge amplitude of output sound.

Abstract: A testing apparatus includes a plate unit including at least one chip mounting unit on which a light emitting diode (LED) to be tested is mounted. The chip mounting unit has a first region in which the LED is overlaid and a second region surrounding the first region. The first and second electrode pads are disposed in the first region and include respective extension portions extended toward the second region. A probe portion is configured to connect to the extension portions of the first and second electrode pads. A power control unit is configured to selectively apply test power to the LED through the probe portion. A light measuring unit is configured to measure light properties of light emitted by the LED.
