     The present invention generally relates to a dissipation device, and more particularly, to a dissipation device based on a heat radiation mechanism. 
     2. Description of Related Art 
     Earphone is a conversion unit that typically has one or two speakers to receive the electrical signals from a media player or receiver and convert it into audible sound waves by using a speaker that is close to the ear. The headphone is usually detachable from the media player and is connected by a plug. With the popularity of consumer electronics devices, headphone has been widely used in devices such as video games, mobile phones, webcast interactions, computers and digital audio players. 
     However, the conventional earphone structure has the disadvantages such as monotonous appearance. With the improvement of aesthetic qualities, users pay increasing attention to the shape and color of the headphones when choosing headphones. As the earphones are used for the purpose of playing, there are also users who use the earphones as wearing accessories. However, the shape and color of the earphones cannot be changed, resulting in excessive consumption of the plurality of sets of earphones.

When the static friction is small, the light cover  30  and the earmuffs  20  are easily adjusted according to the user&#39;s head shape; when the static friction is large, the light cover  30  and the ear cover  20  are easily maintained in a state of manual adjustment by the user. The angle of rotation of the light cover  30  with the headphone  10  and the earmuffs  20  can be in multi-segment or continuous design. 
     Please refer to  FIG. 6  and  FIG. 7 , which are schematic diagrams showing the upper rotation operation and the lower rotation operation of the light cover  30  of the headphone  100  according to the preferred embodiment of the invention. As shown in  FIG. 6 , please compare with  FIG. 2 , and the light cover  30  of  FIG. 6  is rotated upward relative to the earmuffs  20 . The light cover  30  and the translucent housing  40  form a first light-transmitting window  41  exposed to the lower portion of the translucent housing  40 , and the rotation of the light cover  30  relative to the translucent housing  40  changes the area and shape of the first light-transmitting window  41 . The larger the angle at which the light cover  30  is rotated upward compared with the earmuffs  20 , the larger the area and the higher the shape height of the first light-transmitting window  41  is. 
     As shown in  FIG. 7 , please compare with  FIG. 3 , the earmuffs  20  of  FIG. 7  rotates outward so that the angle between the light cover  30  and the translucent housing  40  is less than  180  degrees, and angle between the original light cover and the translucent housing  40  is substantially a plane of 180 degrees. The light shielding cover  30  is relatively rotated downward relative to the angle of the earmuffs  20 . The light cover  30  and the translucent housing  40  further constitute a second light-transmitting window  42  exposed to the upper portion of the translucent housing  40 , and the rotation of the light cover  30  relative to the translucent housing  40  changes the area and size of the second light-transmitting window  42 . The larger the angle at which the light cover  30  is rotated downward relative to the earmuffs  20  is, the larger the area and the higher the shape height of the second light-transmitting window  42  is. 
     When the angle between the light cover  30  and the translucent housing  40  is generally the 180-degree plane in  FIG. 2  and  FIG. 3 , the first light-transmitting window  41  and the second light-transmitting window  42  exposed by the light cover  30  are both thin light-emitting strips. The first light-transmitting window  41  and the second light-transmitting window  42  are located on opposite sides of the light cover  30 . That is, when the first light-transmitting window  41  is smaller, the second light-transmitting window  42  is larger; conversely, when the first light-transmitting window  41  is larger, the second light-transmitting window  42  is smaller. In other embodiments of the invention, the light shielding cover  30  may also partially cover the outer side strip  83  of the main housing  21  and/or the outer side of the semi-circular side plate  84  (not shown in the figure). 
     When using the headphone  100 , for example, by pressing a button on the headphone  100 , rotating the light cover  30  as an instruction or auxiliary software of computer operation, the control board  22  controls the light-emitting components  24  to generate a light conversion effect and convey the vision message to someone other than the wearer. 
     The connection between the light cover  30  and the translucent housing  40  exhibits a variety of physical changes according to the clamping angle, resulting in different light effects, making the headphone  100  of the invention provide a variety of light effects and beautiful visual experience. 
     As mentioned above, the headphone of the present invention has the following advantages. First of all, the headphone has a variety of shapes. The shape and color of the decorative piece, the first light-transmitting window and the second light-transmitting window can be changed according to the needs of the user. Therefore, the user can match a variety of different colors and shapes. Moreover, since the rotation of the light relative to the translucent housing  40  changes the area of the light-emitting window of the light-transmitting casing. The connection between the earmuffs and the light-shielding cover will provide a variety of light effects according to the different clamping angles, providing a varied and gorgeous visual experience. 
     In addition, because the translucent housing is located in a prominent position on the outside of the headphone, the headphone can provide a visual reminder function to convey visual information or alert function to people other than the wearer. In the process of using, the light conversion effect generated by the combination of the control board and the light-emitting components can inform the people other than the wearer of the operation of the invention and achieve the eye-catching effect. In addition, since the two earmuffs are first pivoted to the light cover and then connected to the headgear through the light cover, the headphone of the present invention can provide two different adjustment positions and two different angle plane rotation directions, so the users may use the headphone according to the position where they feel comfortable. 
     Even though numerous characteristics and advantages of certain inventive embodiments have been set out in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only. Changes may be made in detail, especially in matters of 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.
