Abstract:
An angle-adjustable mechanism for a speaker system includes a housing and a plurality of speakers. The housing has an opening for accommodating and pivoting a console within the opening. The housing and the speakers can therefore be rotated to a desired angle relatively to the console. The speaker system may be alternatively coupled, by way of example, to either a computer system or an MP3 player.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a portable speaker system, and in particular to a mechanism enabling speakers to be adjusted relative to a console. 
         [0003]    2. Description of the Prior Art 
         [0004]    Because of the great popularity of MP3 devices and the like, a variety of portable computer speakers capable of being coupled not only to a computer, but also to an MP3 device, have become available. 
         [0005]    Logitech® mm22 Portable Speakers, for example, have base, and a pair of foldable speakers at each end of the base. An MP3 device, such as Apple Corporation&#39;s iPod®, can be inserted into a socket on the base. The user may spread out each of the speakers such that the base and the pair of speakers will assume a U-shape configuration. However, the speakers cannot be adjusted to a preferred angle position, and therefore sound waves generated by the speakers will not be properly projected to the surroundings for premium quality listening. 
         [0006]    Another example is the Logitech® mm50 Portable Speakers system, which has a rigid configuration for installing a pair of speakers at each end of a base. Also, an MP3 device, such as an iPod®, can be inserted into a socket on the base. Again, because the angle of the speakers is fixed, sound waves generated by the speakers will not be properly projected to the surroundings to favor the listener. 
       SUMMARY OF THE DISCLOSURE 
       [0007]    It is an object of the present invention to provide an angle-adjustable mechanism for a portable speaker system, in which a plurality of speakers can be adjusted to a desired angle relatively to a console. 
         [0008]    It is another object of the present invention to provide an angle-adjustable mechanism for a portable speaker, in which the console can be folded into an opening for easy transport. 
         [0009]    To accomplish the advantages mentioned above, the speaker system comprises a housing, and a pair of speakers. Each of the speakers is located at each end of the housing, and the housing has an opening located between the pair of speakers for accommodating a console therebetween. The housing has a top frame and an inner side frame next to the opening, and the console is pivotally connected to the inner side frame. Therefore, the housing, the top frame, the inner side frame and the pair of speakers can be rotated to a desired angle relative to the console.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0014]    The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims. 
         [0015]    Please refer to  FIGS. 1-2 . The speaker system comprises a console  1 , and a housing which further has an upper housing  2  and a lower housing  3 . The console  1  is a controlling device which can control the volume of the speaker or the like via a plurality of buttons  11 . A portable device, such as an MP3 device, or a computer system, may couple to the console by a cable or wireless interface, examples of suitable cable or wireless interfaces being well-known in the field. In addition, each end of the console  1  has an axle  12 , and each of the axles  12  has a neck  121 , and several detent-like lobes  122  which are evenly separated by several grooves  123 . Each end of the housing has a speaker  28  so as to constitute a stereo speaker system. 
         [0016]    The upper housing  2  has a top frame  21 , a pair of side frames  22 , and a pair of bottom frames  23  which are respectively located under the speakers  28 . The upper housing  2  further has a pair of inner side frames  24 , an inner top frame  25 , a gap  26  and an opening  27 . Correspondingly, the lower housing  3  has a top frame  31 , a side frame  32 , and a pair of bottom frames  33  which are respectively located under the speakers  28 . The upper housing  3  further has an inner side frame  34 , an inner top frame  35 , a gap  36  and an opening  37 . 
         [0017]    Each of the inner side frames  24  further has a protrusion  29  which has a recess  291 , a compartment  292 , and a chamber  293 . Correspondingly, each of the inner side frames  34  further has an opening  38  which has a recess  381 , a compartment  382 , and a chamber  383 . In addition, there is a flexible clip  384  located within the chamber  383 . The clip  384  can have a C-shape like configuration. 
         [0018]    Once the upper housing  2 , console  1 , and lower housing  3  are assembled together, the console  1  will be positioned within the openings  27  and  37 . Also the gaps  26 ,  36  will be positioned between the top frames  21 ,  31  and the console  1 . Each of the axles  12  will be contained within the compartments  292  and  382 , and be positioned between the chambers  293  and  383  such that each of the necks  121  will be positioned between the recesses  291  and  381 . Finally, two of the grooves  123  will be captured by the clip  384 . Therefore the console  1  can be rotated within the housing, and the clip  384  can position either the console  1  or the housing at a desired angle. 
         [0019]    Please refer to  FIGS. 3A-3C . When a user places the housing on a table, the user may leave the console  1  on the table and lift the housing up from the gaps  26 , 36  by holding the top frames  21 , 31 . In other words, the housing will be rotated relatively to the console  1 . Due to the groove  123  of the axles  12  bring captured by the clips  384 , the housing can be rotated and positioned at several angles. Once the console  1  is rotated, an upper lobe  122  and a lower lobe  122  of the axle will push and enlarge (deform) the flexible clip  384  in the chambers  293  and  383 , such that the axles  12  can be further rotated step by step. It is understood that when the upper and lower lobes  122  move across the clip  384 , the clip  384  will hold the axles  12  at upper and lower grooves  123 , which is why the housing can be rotated step by step. 
         [0020]      FIG. 4  shows a second embodiment of the invention. The top frames  21  and  31  can be linked by a single handle  6 . The handle  6  couples to each side of the housing. By the structure mentioned above, the user may carry the speaker system for transport by folding the console  1  to be in line with the housing. As in the first embodiment, the console  1  can be rotated within the opening of the housing, and the clip  384  can position either the console  1  or the housing at a desired angle. 
         [0021]    While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
