1. Technical Field
The present disclosure relates to a portable sound box.
2. Description of Related Art
In use, sound boxes need to be placed on a horizontal supporting surface, such as the floor or a desktop, and connected to a local power source, and thus their portability is limited.
Therefore, it is desirable to provide a sound box, which can overcome the above-mentioned limitations.
Many aspects of the present sound box should be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present sound box. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Embodiments of the present sound box will now be described in detail with reference to the drawings.

The PCB 14 may further include a power connector 140, a data connector 141, and a power switch 142, disposed on one end of the PCB 14. The upper casing 17 defines three third through holes 178 corresponding to the power connector 140, the data connector 141, and the power switch 142, and includes a volume controller 172 mounted thereon and connected to the PCB 14. The power connector 140 protrudes from the upper casing 17 through one third through hole 178 and seals the third through hole 178 to allow the sound box 100 connecting to an external power source (not shown). The data connector 141 protrudes from the upper casing 17 through one third through hole 178 and seals the third through hole 178 to allow the sound box 100 to be connected to an audio source (not shown). The power switch 142 protrudes from the upper casing 17 through one third through hole 178 and seals the third through hole 178 to allow booting operation of the sound box 100. The volume controller 172 is disposed on the upper casing 17 to allow manual volume control of the sound box 100. However, the configuration of the power connector 140, the data connector 141, the power switch 142, and the volume controller 172 is not limited to this embodiment.
It is noteworthy that the configuration of the upper casing 17 and the bottom plate 12 is not limited to this embodiment. In other alternative embodiments, the upper casing, the bottom plate, and the opening can be designed in other shapes. Also, the numbers of the speakers 15 and the first through holes 176 are not limited to this embodiment, but should be set depending on requirements.
In particular, the bottom plate 12 includes three positioning columns 122 extending toward the upper casing 17. Each positioning column 122 defines a first through threaded hole 123. The upper casing 17 defines three fastener-receiving columns 173 extending toward and aligned with the corresponding positioning columns 122. The upper casing 17 and the bottom plate 12 are connected by inserting three fasteners (not shown) through the corresponding first through threaded holes 123 and into the corresponding fastener-receiving columns 173. Also, the upper casing 17 and the bottom plate 12 can be combined by other methods, such as, structural engagement or adhesive.
The bottom plate 12 further includes a supporter 143 disposed between the two speakers 15. The upper casing 17 includes a rib 174. The rib 174 is a plate extending toward the bottom plate 12 and positioned between the first through holes 176 and the first hole 177. The rib 174 defines a cutout 175. The inverter tube 16 is supported by the supporter 143 and extends through the cutout 175 to the second through hole 177. Thus, the inverter tube 16 is secured within the resonant chamber by the supporter 143 and the rib 174. Of course, the inverter tube 16 can be fixed in the resonant chamber by other methods in alternative embodiments.
The protective net 18 is pasted on the upper casing 17, covering the first through hole 176 and the second through hole 178 for allowing sound to exit but blocking the entry of dust. To avoid the protection sheet 18 adversely affecting the appearance and interfering with the handling of the sound box 100, the upper casing 17 defines a sunken surface 17b. The protection sheet 18 fittingly fills the sunken surface 17b.
The bottom plate 12 defines a groove 121 in a surface 12a facing away from the upper casing 17. The battery 13 is fittingly received in the groove 121. The cover 11 covers the surface 12a to secure the battery to 13 to the bottom plate 12. In particular, the bottom plate 12 also includes an electrical contact 124 that is disposed in the groove 121 and electrically connected to the PCB 14. The battery 13 is electrically connected to the PCB 14 by the electrical contact 124 and supplies power for the PCB 14. The battery 13 can be a rechargeable battery and recharged by the external power source by the power connector 141.
The bottom plate 12 defines two engagement-receiving portions 125 at one side of the groove 121 and a blind threaded hole 126 at an opposite side of the groove 121. The cover 11 is a flat board and includes a front surface 110 and a back surface 111 opposite to the front surface 110. The back cover 11 includes two engagement portions 112 disposed on the front surface 110 corresponding to the engagement-receiving portions 125. The back cover 11 also defines a second threaded through hole 113 through the front surface 110 and the rear surface 111. The cover 11 is secured to the bottom plate 12 by engaging the two engagement portions 112 with the engagement-receiving portions 125 and inserting a fastener (not shown) through the second through threaded hole 113 and into the blind threaded hole 12. Of course, the cover 11 can be secured to the bottom plate 12 by other methods.
The cover 11 includes two first connecting plates 21 extending upwards from the back surface 111, adjacent to an end of the cover 11. Each first connecting plate 21 defines a first connecting hole 210. The two first connecting holes 21 are aligned with each other. The clip 20 includes a clipping plate 24, a shaft 23, and a coil spring 22. The clipping plate 24 includes two second connecting plates 240 extending upward from a surface of the clipping plate 24, adjacent to an end of the clipping plate 24. Each second connecting plate 240 defines a second connecting hole 241. The second connecting holes 241 are aligned with each other. The distance between the second connecting plates 240 is slightly farther than between the first connecting plates 21. The shaft 23 extends through one second connecting hole 240, one first connecting hole 210, the coil spring 22, the other first connecting hole 210, and the other second connecting hole 240 in sequence. Thus, the clipping plate 24 is connected to the cover 11. The coil spring 22 is configured for applying a torsional force to the clipping plate 24 so that an end of the clipping plate 24 opposite to the second connecting plate 240 abuts the cover 11. In this embodiment, the clipping plate 24 further includes two gripping teeth 241 formed at the end of the clipping plate 12 opposite to the second connecting plates 240 to increase a gripping force of the clip 20.
It will be understood that the above particular embodiments and methods are shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiment thereof without departing from the scope of the disclosure as claimed. The above-described embodiments illustrate the scope of the disclosure but do not restrict the scope of the disclosure.
