  • Publication number: 20110034218
    Abstract: An in-ear earphone includes a housing, a transducer, a sound tube and an earplug. The transducer is disposed in the housing. The sound tube is extended outward from the housing. The sound tube has a first channel connected with the housing for receiving the acoustic wave generated by the transducer, and a second channel connected with first channel and having a cross-section area different from the first channel. The earplug is disposed on the sound tube to be inserted into the ear channel of a user so as to reduce the frequency response of the acoustic wave which is delivered to the ear cannel of the user.

  • Patent number: 7713420
    Abstract: An ion exchange resin tower including a tank, a supply line, an output line, and a plurality of sampling tubes is provided. The supply line guides a liquid into the tank, such that an ion exchange occurs between the liquid and the ion exchange resin in the tank. The processed liquid is guided out of the tank via the output line. The sampling tubes are disposed on a sidewall of the tank to sample the liquid flowing through the resin.

  • Patent number: 6866179
    Abstract: A welding tab assembly has a weld tab and a metal rod. The weld tab has an inverted L-shaped recess defined in one side of the weld tab and an inclined hole defined in a top face of the recess. The metal rod is inverted L-shaped and is received in the inverted L-shaped recess. An inclined section obliquely extends from one end of the metal rod and is received in the inclined hole in the weld tab. A fastener detachably holds the metal rod in the recess. In such an arrangement, the welding slag can be cleaned or exhausted during the welding process by means of detaching the weld tab from the welded parts, such that the welding quality is improved.
