Title: Earphone

Description:
TECHNICAL FIELD 
     The present utility model relates to the field of audio-visual appliances, particularly to an earphone. 
     BACKGROUND ART 
     Generally, for the convenience of production, the shape and size of the left earphone and the right earphone are fixed and consistent for in-ear earphones, which results in the same angle of the left and right earphones into ears. However, since different people have different ear canal structure and even the same person has different left and right ear canals. Thus, the same entry angle for the left and right earphones may cause inconsistent feeling in the left and right ear canals when wearing the earphones, thereby affecting the actual experience of wearers. 
     SUMMARY 
     In order to solve the above problems, the present utility model provides an earphone with adjustable in-ear angle. 
     The present utility model is realized by the following technical solutions: 
     The present utility model provides an earphone, wherein the earphone comprises: 
     a casing, wherein a receiving cavity is formed inside the casing, and the casing is provided with a first mounting hole connecting with the receiving cavity; 
     a mounting plate, wherein the mounting plate is fixedly mounted in the receiving cavity and the mounting plate completely blocks the first mounting hole from connecting with the receiving cavity; and one end of the mounting plate adjacent to the first mounting hole is provided with a sound-transmitting groove; and
 
a sound guiding tube, wherein one end of the sound guiding tube is a movable end, and the other end of the sound guiding tube is a mounting end, and a sound guiding channel passing through the movable end and the mounting end is provided inside the sound guiding tube so that when the movable end portion is installed in the first mounting hole the sound guiding channel connects with the sound-transmitting groove and the movable end can rotate in the first mounting hole so as to enable the sound guiding tube to rotate relatively to the casing; and the sound guiding tube can be installed into the first mounting hole or be detached from the first mounting hole manually.
 
     In addition, a first mounting slot is disposed at one end of the mounting plate away from the first mounting hole, a first sound-transmitting hole is disposed at a bottom of the first mounting slot, and the first sound-transmitting hole is in connection with the sound-transmitting groove. 
     In addition, a second mounting slot is further disposed at one end of the mounting plate away from the first mounting hole, a second sound-transmitting hole is disposed at a bottom of the second mounting slot, and the second sound-transmitting hole is in connection with the sound-transmitting groove. 
     In addition, the earphone further comprises: a cover plate, which is fixedly connected to an end of the casing away from the first mounting hole. 
     In addition, the earphone further comprises: a decorative plate, which is mounted at an end of the cover plate away from the casing and can be manually mounted to the cover plate or detached from the cover plate. 
     In addition, the earphone further comprises: an earplug sleeve, which is detachably sleeved on the mounting end. 
     The beneficial effects of the present utility model are as follows: 
     The earphone provided by the present utility model can adjust the in-ear angle, which improves the wearing comfort and thereby improve the sound quality of the earphone. In addition, the sound guiding tube can be manually removed from or installed to the casing, which is very convenient for users to replace the sound guiding tube or clean the earphones.

     DETAILED DESCRIPTION 
     In order to explain the technical solutions of the present utility model more clearly and completely, the present utility model will be further described as below in conjunction with the attached drawings. 
     Please refer to  FIG. 1  to  FIG. 3 , the present utility model provides an earphone, wherein the earphone comprises: 
     a casing  10 , wherein a receiving cavity  11  is formed inside the casing  10 , and the casing  10  is provided with a first mounting hole  12  connecting with the receiving cavity  11 ; 
     a mounting plate  20 , wherein the mounting plate  20  is fixedly mounted in the receiving cavity  11  and the mounting plate  20  completely blocks the first mounting hole  12  from connecting with the receiving cavity  11 ; and one end of the mounting plate  20  adjacent to the first mounting hole  12  is provided with a sound-transmitting groove  21 ; and
 
a sound guiding tube  30 , wherein one end of the sound guiding tube  30  is a movable end  31 , and the other end of the sound guiding tube  30  is a mounting end  32 , and a sound guiding channel  33  passing through the movable end  31  and the mounting end  32  is provided inside the sound guiding tube  30  so that when the movable end  31  portion is installed in the first mounting hole  12  the sound guiding channel  33  connects with the sound-transmitting groove  21  and the movable end  31  can rotate in the first mounting hole  12  so as to enable the sound guiding tube  30  to rotate relatively to the casing  10 ; and the sound guiding tube  30  can be installed into the first mounting hole  12  or be detached from the first mounting hole  12  manually.
 
     In the present embodiment, when a user wears the earphone, the in-ear angle of the earphone is adjusted by rotating the sound guiding tube  30  to achieve optimal wearing comfort, thereby improving the sound quality of the earphone; and in addition, the sound guiding tube  30  can be manually mounted into the first mounting hole  12  or detached from the first mounting hole  12 , and a user can replace the sound guiding tube  30  according to actual conditions, which improves wearing comfort and sound quality of the earphone to the maximum extent. The earphone provided by the present utility model can adjust the in-ear angle of the earphone, which improves the wearing comfort and thereby improve the sound quality of the earphone. In addition, the sound guiding tube  30  can be manually removed from or installed to the casing  10 , which is very convenient for users to replace the sound guiding tube  30  or clean the earphone. 
     Please refer to  FIG. 1  and  FIG. 2 . A first mounting slot  24  is disposed at one end of the mounting plate  20  away from the first mounting hole  12 , a first sound-transmitting hole  22  is disposed at a bottom of the first mounting slot  24 , and the first sound-transmitting hole  22  is in connection with the sound-transmitting groove  21 .
