BACKGROUND OF THE INVENTION  
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a speaker capable of emitting light, and more particularly, to a speaker with a housing formed as a speaker chamber of the speaker and for conducting light generated by light generators, so as to have a function of emitting light. 
         [0003]    2. Description of the Prior Art 
         [0004]    With technological advancement, processing speeds of electronic devices become faster and faster, while sizes of the devices become smaller and smaller. Thus, generally speaking, the electronic devices nowadays already satisfy basic demands of consumers, such that more and more attention is paid to multimedia functions of the electronic devices. Taking computers for example, when basic calculation performance reaches basic requests of the consumers, multimedia effects of the computers become a focus for choosing such products. Among multimedia devices of computers, speakers are basic equipment, designed for generating sound originally, however, no longer satisfies consumers anymore. Therefore, except for generating sound, the speakers should have a function of emitting light, so as to attract consumers. 
         [0005]    Please refer to  FIG. 1 , which is a cross-section diagram of a prior art speaker  10  with a function of emitting light. The speaker  10  includes a speaker chamber  110 , a speaker core  120 , a light pipe  130  and light emitting diodes (LED) D 1  and D 2 . The speaker chamber  110  includes an opening  115  utilized for installing the speaker core  120 . Functions of the speaker chamber  110  and the speaker core  120  are well known for those skilled in the art, and thus are not repeated here. The light pipe  130  is installed on the opening  115  of the speaker chamber  110 , and is utilized for providing a light propagation path to conduct light emitted by the LEDs D 1  and D 2 . Therefore, the speaker  10  not only generates sound by the speaker core  120 , but also propagates and emits light by the light pipe  130  installed on the opening  115  of the speaker chamber. 
         [0006]    Please proceed to  FIG. 2 , which is a schematic diagram of the light pipe  130  installed on the opening  115  of the speaker chamber. The light pipe  130  includes an acrylic ring  132 , a reflector  134 , a diffuser  136  and a circuit board  138 . The acrylic ring  132  can be considered as a light carrier, and includes a first light reception terminal  1320  and a second light reception terminal  1325  for receiving light emitted by the LEDs D 1  and D 2  respectively. The reflector  134  and the diffuser  136  are respectively installed on the top and the bottom of the light pipe  130 , which are utilized for propagating the light emitted by the LEDs D 1  and D 2  evenly, and the light propagation direction is as shown in  FIG. 2 . The circuit board  138  is utilized for attaching the LEDs D 1  and D 2  and for laying out related circuits. Moreover, the light pipe  130  can include a fixture (not shown in  FIG. 2 ) for assembling the light pipe  130  on the speaker chamber. Since the light pipe  130  needs to be composed by the components mentioned above, the speaker  10  capable of emitting light has great thickness and occupies too much space, so that it is not suitable for current electronic devices with small sizes and light weight. Moreover, the light pipe  130  is composed of too many components, so that the production cost of the speaker  10  is high and the quality is not stable as well.

     DETAILED DESCRIPTION  
       [0017]    Please refer to  FIG. 3 ,  FIG. 4  and  FIG. 5 .  FIG. 3  is a cross-sectional schematic diagram of a speaker  30  capable of emitting light according to an embodiment of the present invention,  FIG. 4  is a back-view schematic diagram of the speaker  30  of the present invention, and  FIG. 5  is a top-view schematic diagram of the speaker  30  of the present invention. The speaker  30  comprises a housing  310 , light generators L 1 ˜Ln and a speaker core  330 . The housing  310  is formed by material capable of propagating light, and comprises a first opening  312  and a second opening  314 . The light generators L 1 ˜Ln are installed nearby the second opening  314  for generating light. The speaker core  330  is installed on the first opening  312  of the housing  310 , and is utilized for generating sound. Furthermore, the second opening  314  of the housing  310  is a light reception terminal for receiving light generated by the light generators L 1 ˜Ln, the first opening  312  of the housing  310  is a light emission terminal for emitting light, and the housing  310  is a light carrier for providing a light propagation path, which can be formed by transparent or semi-transparent material that is capable of propagating light, such as acrylic, glass, etc. Preferably, the housing  310  can be a speaker chamber of the speaker  30 , and the light generators L 1 ˜Ln can be light emitting diodes (LED). 
         [0018]    Therefore, in the present invention, the speaker  30  can generate sound by the speaker core  330  according to input signals. On the other hand, the speaker  30  can also propagate light generated by the light generators L 1 ˜Ln with the housing  310  formed as the speaker chamber of the speaker  30 , so that the speaker  30  can have a function of emitting light. 
         [0019]    Please refer to  FIG. 3 . The speaker  30  of the present invention further comprises an elastic body  350 . The elastic body  350  is installed between the speaker core  330  and the first opening  312  of the housing  310 , and is utilized for jointing the speaker core  330  and the housing  310  and for confining a vibration direction of the speaker core  330 . Preferably, the elastic body  350  can be a foam rubber. When light is generated by the light generators L 1 ˜Ln, the light generated by the light generators L 1 ˜Ln can be received with the second opening  314  of the housing  310 . Then, the light is propagated through the housing  310  to the first opening  312 , so as to be emitted. Therefore, as shown in  FIG. 3 , the light generated by the light generators L 1 ˜Ln can be conducted from the second opening  314  to the first opening  312  through the housing  310 , so that the light can be emitted evenly from the first opening  312 . Please note that a shape of the housing  310  is merely an exemplary embodiment of the present invention, and those skilled in the art can make appropriate modifications according to practical demands, which all belong to the category of the present invention. Moreover, the light generators L 1 ˜Ln can be further coupled to a control circuit (not shown in the figure). The control circuit can control intensity or frequency of the light generated by the light generators L 1 ˜Ln according to signals inputted to the speaker core  330 . 
         [0020]    Compared with the prior art, the speaker capable of emitting light according to the present invention does not need to utilize extra light pipes, and directly utilizes the speaker chamber of the speaker for providing the light generators with a light propagation path to achieve an equal light emitting function. Therefore, the present invention can reduce usage of related components, such as diffusers and reflectors, so that the production cost and the thickness can be saved, and thus is suitable for the current electronic devices of small sizes and light weight. Moreover, compared with the prior art that utilizes reflectors for reflecting the light propagating in the light pipe, the present invention directly propagates and emits light through the speaker chamber, so that light emission efficiency of the present invention is higher than that of the prior art. 
         [0021]    Please refer to  FIG. 6 , which is a schematic diagram of a multimedia device  60  with speakers capable of emitting light according to an embodiment of the present invention. The multimedia device  60  comprises a multimedia processing system  610  and speakers S 1 ˜Sn. As shown in  FIG. 6 , the multimedia device  60  preferably is a notebook computer. The multimedia processing system  610  is utilized for processing multimedia signals. The speakers S 1 ˜Sn are installed on the multimedia device  60 , and are utilized for outputting processing results of the multimedia processing system  610 . Each of the speakers S 1 ˜Sn is the speaker  30  capable of emitting light shown in  FIG. 3 . Hence, not only can the speakers S 1 ˜Sn generate sound according to the processing results of the multimedia processing system  610 , but also can generate light corresponding to the sound generated by the speakers. Therefore, with the multimedia device  60 , the sound can be heard and ‘seen’ as well by users. Please note that the multimedia device with speakers capable of emitting light of the present invention is not restricted to a notebook computer, and can be a desktop computer, a mobile communication device, or audio equipment. 
         [0022]    As mentioned above, the speaker capable of emitting light of the present invention utilizes a housing formed as a speaker chamber of the speaker and for conducting light generated by light generators, so as to have a function of emitting light. Furthermore, the present invention can reduce usage of related components, such as diffusers and reflectors, so that the production cost and the thickness can be saved, and thus is suitable for the current electronic devices of small sizes and light weight. 
         [0023]    Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
