Title: Vibration absorbing member and audio apparatus using the same

Description:
BACKGROUND 
     1. Field of the Invention 
     Embodiments of the present disclosure generally relate to absorbers, and particularly, to a vibration absorbing member and an audio apparatus using the same. 
     2. Description of Related Art 
     Audio apparatus generally includes a speaker and a plate-like vibration absorbing member. An opening is defined in a front surface of the speaker for allowing sound waves reproduced by the speaker to radiate out of the audio apparatus. The vibration absorbing member is detachably attached to the speaker at the front surface of the speaker, with a through hole of the vibration absorbing member corresponding to the opening of the speaker. 
     When the speaker is assembled in a cabinet, the vibration absorbing member is disposed between the speaker and the cabinet the vibration absorbing member may separate from the speaker if the speaker is not tightly attached to the vibration absorbing member. 
     As such, a need exists for a vibration absorbing member that can be tightly attached to the speaker.

     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , an audio apparatus  10  in accordance with an exemplary embodiment includes a vibration absorbing member  100  and a speaker  200  disposed in the vibration absorbing member  100 . 
     Further referring to  FIGS. 2 and 3 , the speaker  200  includes an approximately rectangular parallelepiped frame  21  and an electroacoustical transducer  22  disposed in the frame  21 . 
     The electroacoustical transducer  22  is a sound source generator of the speaker  200 . The electroacoustical transducer  22  includes a diaphragm, a voice coil, a pole piece, and so on (not shown). 
     The frame  21  has a front surface  211 , a back surface  212 , and a side surface  213  connecting and surrounding the front surface  211  and the back surface  212 . The frame  21  defines four first through holes  215  extending from the front surface  211  to the back surface  212 . An opening  216  is defined in the front surface  211  of the frame  21 . The opening  216  is used for allowing sound reproduced by the electroacoustical transducer  22  to radiate out of the speaker  200 . 
     The vibration absorbing member  100  is made of flexible material, such as rubber, sponge, and so on. The vibration absorbing member  100  is integrally formed. The vibration absorbing member  100  defines an approximately rectangular parallelepiped housing  16  for receiving the speaker  200  and absorbing vibration of the speaker  200 . The size of the housing  16  is slightly smaller than that of the speaker  200 , such that the vibration absorbing member  100  can tightly enclose the speaker  200 . The vibration absorbing member  100  includes a plate-like vibration absorbing portion  11 , a fastening portion  13 , and a sub-fastening portion  15 . The fastening portion  13  connects the vibration absorbing portion  11  with the sub-fastening portion  15 . 
     The vibration absorbing portion  11  is used for absorbing vibration of the speaker  200 . The vibration absorbing portion  11  defines a through hole  112  corresponding with the opening  216  of the speaker  200  for allowing the sound from the opening  216  to radiate out, and four second through holes  114  corresponding with the four first through holes  215  of the speaker  200 . 
     The fastening portion  13  includes four sidewalls vertically extending from four edges of the vibration absorbing portion  11 . Each of the four sidewalls is rectangle-shaped. The fastening portion  13  is capable of tightly sleeving the side surface  213 , such that the vibration absorbing member  100  can be attached to the speaker  200 . 
     The sub-fastening portion  15  includes two fastening plates  151 ,  152  parallel with the vibration absorbing portion  11 . The two fastening plates  151 ,  152  respectively connect with two opposite side edges  133  of the fastening portion  13 . The two fastening plates  151 ,  152  are spaced apart from each other, and define a space  131  therebetween to allow the speaker  200  to be easily inserted into the vibration absorbing member  100  through the space  131 . The two fastening plates  151 ,  152  define four third through holes  154  corresponding with the four second through holes  114  and the four first through holes  215 . The first, second, and third through holes  215 ,  114 ,  215  allow fastening members (not shown), such as screws, to pass through, in order for the speaker  200  to be fastened to the vibration absorbing member  100 . 
     In assembly, the speaker  200  is inserted into the vibration absorbing member  100  from the space  131  between the two fastening plates  151 ,  152 , and the front surface  211  faces the vibration absorbing portion  11 . Because the fastening portion  13  tightly sleeves the side surface  213  of the speaker  200 , the vibration absorbing portion  11  is tightly attached to the front surface  211 , and the two fastening plates  151 ,  152  are tightly attached to the back surface  212 . As a result, the vibration absorbing member  100  can tightly attached on the speaker  200 . 
     It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the present disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
