  • Publication number: 20160065638
    Abstract: A voice transmission system includes at least one electronic device and a controller. The at least one electronic device is connected to an internet. The controller is connected to the at least one electronic device over a wireless local area network channel for conducting a unidirectional voice transmission. The at least one electronic device includes a first communication module and a speaker unit. The first communication module receives a first voice signal from the internet, and the speaker unit plays the first voice signal. The controller includes a voice receiving unit and a second communication module. The voice receiving unit receives a second voice signal, and the second communication module transmits the second voice signal to the first communication module of the at least one electronic device over the wireless local area network. The first communication unit further transmits the second voice signal received to the internet.

  • Patent number: 7550058
    Abstract: The present invention relates to the technical field of manufacturing engineer wood floor for indoor decoration, and in particular to a manufacturing method that does not release any dissociated formaldehyde. The manufacturing steps are as the followings: Mix the adhesive agent; pour the mixed adhesive agent on a glue spreader at the linear velocity of ?20 meters/minute; deliver the wooden middle boards to the glue spreader to carry out spreading glue; superimpose wooden middle boards having been coated with glue longitudinally and latitudinally, and deliver them to a cold press for cold press; put the rough middle boards having been coldly pressed on a hot press for hot pressing, in order to make them become base material of engineer wood floor; Stick decorative surface material on the base material of engineer wood floor in order to make them become a engineer wood floor; and form, paint, and pack the engineer wood floor finally.
