Title: Speaker assembly

Description:
FIELD OF THE PRESENT DISCLOSURE 
     The present disclosure relates to the technical field of electro-acoustic transducers, and more particularly to a speaker assembly used in a portable electronic device. 
     DESCRIPTION OF RELATED ART 
     In the related technology, the speaker assembly includes a frame, a pin, a magnetic circuit system and a vibration system contained in the frame. The pin is provided with a pin convex hull for testing. 
     However, after many tests, it is easy to scratch the pin convex hull, which leads to reduction of performance of the speaker assembly and poor appearance of the speaker assembly. 
     Therefore, it is necessary to research an improved speaker assembly with new structure to solve the problem mentioned above.

     DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT 
     The present disclosure will hereinafter be described in detail with reference to an exemplary embodiments. To make the technical problems to be solved, technical solutions and beneficial effects of the present disclosure more apparent, the present disclosure is described in further detail together with the figure and the embodiments. It should be understood the specific embodiments described hereby is only to explain the disclosure, not intended to limit the disclosure. 
     As shown in  FIGS. 1-5 , the present disclosure provides a speaker assembly  100  in accordance with an exemplary embodiment. The speaker assembly  100  comprises a housing  1 , an electrical connector  2  fixed to the housing  1 , a magnetic circuit system  3  and a vibration system  4  accommodated in the housing  1 , a frame  5  fixed to the housing  1 , and a front cover  6  disposed on the frame  5 . 
     The housing  1  is provided with a positioning column  11  at a corner thereof, the frame  5  is provided with a positioning hole  51  at a position corresponding to the positioning column  11 . The housing  1  and the frame  5  are fixed by the positioning column  11  and the positioning hole  51 . The housing  1  comprises a first installation part  12  and a second installation part  13  located outside the first installation part  12 . The first installation part  12  is provided with an installation hole  14  through its thickness (i.e., penetrating the first installing part  12 ), and the second installation part  13  is provided with a plug-in trough  15  recessed from an upper surface to a lower surface. 
     The magnetic circuit system  3  comprises a magnet assembly  31  and a magnetic yoke  32  for carrying the magnet assembly  31 . 
     The vibration system  4  includes a diaphragm  41  and a voice coil  42  for driving the diaphragm to vibrate and produce sound. 
     The electrical connector  2  includes a body part  21 , a first pad part  22  connected with the body part  21 , a first connecting part  23  connecting the body part  21  with the first pad part  22 , a second pad part  24  spaced apart from the first pad part  22  and a second connecting part  25  connecting the first pad part  22  with the second pad part  24 . The first pad part  22  is installed on one surface of the housing  1  and electrically connected with the voice coil  42 . The second pad part  24  is installed on another surface of the housing  1  and exposed outside the housing  1  for testing the vibration performance of the speaker assembly  100 . The second pad part  24  penetrates the installation hole  14 , and the body part  21  is inserted in the plug-in trough  15 . The upper surface of the second pad part  24  and the upper surface of the installation hole  14  are coplanar with each other. The installation hole  14  can be a square hole, of course, in addition, the installation hole  14  can also be a circular hole or elliptical hole, of course, the installation hole  14  should be suitable for the second pad part  24 . In addition, the second pad  24  and the installation hole  14  can be effectively fixed by transition fit or interference fit. 
     The speaker assembly  100  comprises two electrical connectors  2 , and these two electrical connectors  2  are centrally symmetrically arranged relative to a center of the housing  1 . 
     The speaker assembly  100  of the embodiment includes an electrical connector  2 , and the electrical connector  2  includes a body part  21  and a second pad part  24  connected with the body part  21 . In this way, we can measure flux or test pure tone and performance of the finished product through the second pad part  24  during assembling of the speaker assembly  100  of the structure, so as to prevent the body part  21  from being scratched caused by contact in the traditional test process, thus improving the appearance yield of the finished product. 
     It is to be understood, however, that even though numerous characteristics and advantages of the present exemplary embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the 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 invention to the full extent indicated by the broad general meaning of the terms where the appended claims are expressed.
