  • Publication number: 20150350757
    Abstract: The present invention provides an improved speaker structure, which includes a speaker body, a resonance body and at least one sound guiding portion. The resonance body includes a resonance film and a resonance film frame. The sound guiding portion includes a first sound guiding member, a second sound guiding member and a back frame unit. The speaker structure forms a sealed sound chamber by combining the speaker body, the resonance body and the at least one sound guiding portion. When the speaker body generates a front sound wave and a guiding sound wave, the front sound wave is transmitted within the sound chamber to the resonance film to enhance low frequency sound effect, and the guiding sound wave is transmitted within the resonance cavity and forms a back sound wave, thus reducing noise in the sound region and enabling better extension of the sound wave towards low frequency range.

  • Patent number: 8867778
    Abstract: A loudspeaker has a short support post joined to the forward plate; upper end of the support post in association with the fixing post is joined to the middle part of the drum paper with the fixing post; the voice coil has the upper end thereof joined to the drum paper; when the voice coil drives the drum paper to vibrate and emit sound, the upper end of the short support post sways and generates a small offset because of the lower end of the support post being retained by the forward plate such that the voice coil moves axially in the magnetic clearance without deviation, and the voice coil is incapable of touching the yoke or the forward plate to produce noise; therefore, quality of sound output from the loudspeaker is enhanced effectively.

  • Publication number: 20110301058
    Abstract: A novel approach for fabricating Monolithic Internal micro Pillars (MIPi) made of SU-8 photoresist is described. A microfluidic chip with the internal pillars (a MIPi chip) was used for cell capturing study. The surface of MIPi was coated with specific antibody and then used for capturing cells by affinity binding. An antibody, anti-EGFR, which has high affinity to lung cancer cells, CL1-5, was coated on the micro pillars. The coated MIPi chip specifically captured the cancer cells that were pumped through the MIPi chip. Simulation and experiment was carried out to compare the effect of different geometry of the micro pillars on the cell capturing rate.

  • Patent number: 4484063
    Abstract: A convection oven being an air distribution chamber above the main cooking compartment is the subject of the present invention. A centrifugal fan draws air from the cooking compartment into the air chamber and directs the air outwardly past an electrical heating element mounted within the air chamber in a serpentine configuration. The heated air passes from the air chamber into the cooking compartment through a series of slots which are arranged in a non-symmetrical pattern in order to heat the cooking compartment uniformly for uniform cooking of the food.
