     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIGS. 1-4 , a sound effect amplification diffuser in accordance with the present invention is shown. The sound effect amplification diffuser comprises a deck  1 , and an amplification diffuser  2 . 
     The deck  1  comprises a base member  11 , a cover member  12  covering the base member  11 , an accommodation chamber  10  defined in between the base member  11  and the cover member  12 , a plurality of screw nails  111  fastened to respective corner areas of the base member  11  and the cover member  12  to affix the base member  11  and the cover member  12  together. The cover member  12  has a recessed sloping top wall defining a bearing space  120 , a sound collection hole  121  cut through the opposing top and bottom walls thereof and disposed at one lateral side of the bearing space  120 , a sound collecting hood  122  mounted at the bottom wall thereof around the sound collection hole  121  and suspending in the accommodation chamber  10 , a sound chamber  1220  defined in the sound collecting hood  122  in communication with the sound collection hole  121 , a sound outlet  123  located at one side of the sound collecting hood  122  in communication between the sound chamber  1220  and the accommodation chamber  10 , and a sound grille  13  located at one side wall  101  thereof opposite to the sound collection hole  121  and kept in communication between the accommodation chamber  10  for the passing of sound. 
     The amplification diffuser  2  comprises a trumpet-like sound guide body  21 , a connection hole  211  located at one end of the trumpet-like sound guide body  21  and connected to the sound outlet  123  at the cover member  12  of the deck  1 , a horn mouth  212  located at an opposite end of the trumpet-like sound guide body  21  in communication with the connection hole  211 , and a mounting structure  22  located at the periphery adjacent to the connection hole  211 . 
     When assembling the sound effect amplification diffuser, attach the connection hole  211  of the amplification diffuser  2  to the sound outlet  123  of the sound collecting hood  122  at the cover member  12  of the deck  1  and the horn mouth  212  of the amplification diffuser  2  to the inner side of the sound grille  13  located at one side wall  101  of the cover member  12  of the deck  1 , and then affix the mounting structure  22  of the amplification diffuser  2  to the bottom wall of the cover member  12  of the deck  1  by screw nails  231  (or rivets or an adhesive), and then affix the base member  11  of the deck  1  to the cover member  12  by screw nails  111 , keeping the amplification diffuser  2  in the accommodation chamber  10  in between the base member  11  and the cover member  12 . 
     Referring to  FIGS. 5-7  and  FIGS. 2 and 3  again, during application of the sound effect amplification diffuser, a mobile electronic device  3  (iPad, other tablet computer or smart phone) can be positioned in the bearing space  120  at the top side of the cover member  12  of the deck  1  steadily and then operated to run a software program or any particular function. Further, an elongated locating groove  14  is formed in the bearing space  120  and configured subject to the cross-sectional size of one predetermined mobile electronic device  3  for holding this predetermined mobile electronic device  3  in the bearing space  120  at the top side of the cover member  12  of the deck  1  steadily in vertical. 
     Further, the bearing space  120  at the top side of the cover member  12  of the deck  1  is configured to fit different mobile electronic devices  3 . When putting a mobile electronic device  3  in the bearing space  120 , keep the speaker  31  of the mobile electronic device  3  in proximity to the sound collection hole  121  of the cover member  12  of the deck  1 . When the mobile electronic device  3  is playing a music or video file, sound waves outputted by the mobile electronic device  3  go through the sound collection hole  121  of the cover member  12  into the sound chamber  1220  in the sound collecting hood  122 , and then go through the sound outlet  123  of the sound collecting hood  122  toward the outside of the sound effect amplification diffuser via the horn mouth  212  of the trumpet-like sound guide body  21  and the sound grille  13  of the cover member  12  of the deck  1 . When wound waves pass through the trumpet-like sound guide body  21  of the amplification diffuser  2 , a resonance effect is produced to enhance the intensity of sound. Thus, subject to the design of the bearing space  120  at the top side of the cover member  12  of the deck  1  and the arrangement of the amplification diffuser  2  in the deck  1 , the sound effect amplification diffuser can hold a mobile electronic device  3  steadily in place and enhance the intensity of the output sound of the mobile electronic device  3 . 
     In actual application of the present invention, the sound effect amplification diffuser provides the following features and advantages:
     1. Subject to the arrangement of the amplification diffuser  2  in the deck  1  to keep the connection hole  211  of the amplification diffuser  2  in communication with the sound outlet  123  of the sound collecting hood  122  at the cover member  12  of the deck  1  and the horn mouth  212  of the amplification diffuser  2  in communication with the sound grille  13  located at one side wall  101  of the cover member  12  of the deck  1 , the sound effect amplification diffuser can hold a mobile electronic device  3  steadily in the bearing space  120  at the top side of the cover member  12  of the deck  1  and enhance the intensity of the output sound of the mobile electronic device  3 .   2. The bearing space  120  at the top side of the cover member  12  of the deck  1  is configured to fit different mobile electronic devices  3  so that any of a variety of mobile electronic device  3  can be positioned in the bearing space  120  at the top side of the cover member  12  of the deck  1  steadily, enabling the intensity of its output sound to be enhanced.   

     In general, the invention provides a sound effect amplification diffuser, which comprises a deck, which comprises a cover member, which defines a bearing space at the top side thereof, a sound collection hole at one lateral side of the bearing space, a sound collecting hood at the bottom side thereof around the sound collection hole, a sound outlet at one side of the sound collecting hood and a sound grille at one side wall thereof, a base member affixed to the bottom side of the cover member and an accommodation chamber defined in between the base member and the cover member, and an amplification diffuser, which comprises a trumpet-like sound guide body suspending in the accommodation chamber of the deck, a connection hole located at one end of the trumpet-like sound guide body connected to the sound outlet at the cover member of the deck, a horn mouth located at an opposite end of the trumpet-like sound guide body and connected to the sound grille of the deck. Subject to the design of the deck and the arrangement of the amplification diffuser in the deck, the sound effect amplification diffuser can hold a mobile electronic device steadily in the bearing space at the top side of the cover member of the deck and enhance the intensity of the output sound of the mobile electronic device. 
     Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
