BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1A is a front perspective view of a portable audio system according to one embodiment of the invention.
FIG. 1B illustrates another first perspective view of the portable audio system of FIG. 1A.
FIG. 2B illustrates a back perspective view of the portable energy source of FIG. 2A.
DETAILED DESCRIPTION Exemplary acoustic waveguides can be found in U.S. Pat. Nos. 4,628,528 and 6,278,789 and patent application Ser. No. 10/699,304, filed Oct. 31, 2003.
The portable audio system 100 can also include a power input terminal 123 for connecting an external power source (not shown) to the portable audio system 100. The external power source can supply power to the portable audio system 100 and can also charge the portable energy source 120. An auxiliary audio input terminal 124 can be used to connect an external audio source (now shown) to the portable audio system 100. The external audio source (not shown) can include a MP3 player, a CD player, a DVD player, a satellite radio, a terrestrial radio, a tape player, a PDA, a computer, a cellular telephone, and/or a digital camera.
The bottom surface 126 of the housing 102 can include feet 128. The feet 128 can be fabricated from rubber, plastic, silicone, polypropylene, or any other suitable material. In one embodiment, the feet 128 mechanically isolate the portable audio system 100 from the surface on which it sits. The feet 128 can also prevent the portable audio system 100 from �walking� across the surface when the portable audio system 100 is outputting an audio program. A foot 129 can also be attached to a bottom surface 130 of the portable energy source 120.
The docking cradle 150 can be coupled to the housing 102 through various mechanical techniques. In one embodiment, the docking cradle 150 includes an aperture 154 having a lip 156. A hollow rod 158 or tube that is coupled to the housing 102 fits inside the aperture 154 such that the docking cradle 150 rotates around the hollow rod 158. The lip 156 provides a bearing surface that allows the docking cradle 150 to rotate about the hollow rod 158. The hollow rod 158 also acts as a conduit for cables 160 emanating from the docking cradle 150 that terminate inside the housing 102.
In one embodiment, the docking cradle 150 also includes a gear or pinion 162 that is coupled to a vicious damper (not shown). The vicious damper can be embedded within the docking cradle 150. The vicious damper can also be viscous grease applied to the gear or pinion 162. The viscous damper allows the docking cradle 150 to rotate smoothly from the closed position to the open position and vice versa. The pinion 162 engages a rack (not shown) that is located within the housing 102.
In one embodiment, the docking cradle 150 is mounted to the housing 102 such that various electrical and mechanical features on the docking cradle 150 are located on the portion of the docking cradle 150 that is always concealed by the housing 102. For example, the pinion 162, the latching mechanism 166, the stop 164, the cables 160, and the hollow rod 158 are concealed by the housing 102 when the docking cradle 105 is either in the open position, the closed position, or any transitional position between the open and the closed positions.
FIG. 4 illustrates a bottom view of a section 180 of the housing 102 that accommodates the docking cradle 150. The section 180 includes a rack 182 that engages the pinion 162 (FIG. 3) including the viscous damper on the docking cradle 150. The rack 182 can be secured to the housing 102 using various techniques. In one embodiment, the rack 182 is molded into the housing 102. The rack 182 and pinion 162 provide a controlled motion when the docking cradle 150 is transitioned between the closed position and the open position. In this embodiment, the shape of the rack 182 is semi-circular having a specific radius. However, the rack 182 can be any suitable shape and/or size. Additionally, the number and size of the teeth on the rack 182 and pinion 162 can be selected based on design parameters.
The section 180 of the housing 102 also includes the catch 184 that engages the latch 166 (FIG. 3). The latch 166 engages the catch 184 when rotation the docking cradle 150 to the closed position. The latch 166 disengages the catch 184 when the right side of the docking cradle 150 is pushed towards the housing 102. Other latching mechanisms can also be used such as a spring loaded touch latch.
FIG. 5C illustrates a side view of the portable audio system 100. The front surface 190 of the portable audio system 100 is set to a predetermined angle 196 relative to a vertical plane 198. In one embodiment, the angle 196 is 11.5 degrees. Other angles can also be used. The angle provides an upward tilt to the front surface 190 of the portable audio system 100. Additionally, the angle provides increased mechanical stability to the portable audio system 100. In some embodiments, an external audio source, such as a MP3 player can include an angled base which causes the external audio source to lean at a different angle when inserted into the docking cradle 150. In this example, the docking cradle 150 can be independently tilted to maintain the angle specified by the manufacturer of the external audio source. Alternatively, a docking cradle adapter or insert can be used having a shape that facilitates the proper positioning of the external audio device. For example, if the lean angle on an external audio device is 15.0 degrees and the lean angle of the portable audio system 100 is 11.5 degrees, than the docking cradle 150 can include a lean angle of 3.5 to compensate for the difference. In one embodiment, a bottom surface of the pocket 170 of the docking cradle 150 shown FIG. 3 can be oriented at any desired angle relative to the front surface 190 of the portable audio system 100.
An open end 200 of a waveguide 202 is also shown exiting the back surface 192 of the housing 102. The open end 200 can be shaped and sized to function as handle for the portable audio system 100. A similar location and shape can also be used for the exit of a port in a portable audio system utilizing a ported acoustic enclosure (not shown) instead of a waveguide. The opening for either waveguide or port can generically be referred to a an acoustic exit. For example, the open end 200 can be shaped to facilitate the grasping of the housing 102 with multiple fingers from a human hand. The handle can be used to move the portable audio system 100.
FIG. 6B illustrates rear perspective view of the portable audio system 100 of FIG. 6A. One technique to carry the portable audio system 100 is shown. One or more fingers 204 of a human hand 206 are inserted into the acoustic exit 200 of the waveguide 202. The thumb 208 of the hand 206 can rest against the front surface 190 (FIG. 5A) of the portable audio system 100. Alternatively, the thumb 208 can rest against a top surface 210 of the portable audio system 100.
Although the third subsection 264 connecting the first 252 and second subsections 254 can be twisted in order to transition from the first aspect ratio to the second aspect ratio (from the first axis 156 to the second axis 258), the waveguide, which is normally constructed of an injection moldable material such as plastic, would thus be a difficult structure to mold that would require complex tooling. FIG. 7B is an exploded view of the waveguide 250 of FIG 7A, illustrating a simple, easily moldable waveguide structure. As shown, the first aspect ratio 285 (cross section cut through the A-A′ plane) of the third subsection 264 and the second aspect ratio 286 (cross section cut through the B-B′ plane) are represented as cross sections having long and short dimensions in the X-Y axis, with the long dimension in the X-axis at the first aspect ratio 285 and the long dimension in the Y-axis at the second aspect ratio 286, whereby the X-axis and the Y-axis do not rotate in the transition from the first aspect ratio 285 to the second aspect ratio 286 but rather the dimension in the X-axis gradually changes from the long dimension to the short dimension and the dimension in the Y-axis simultaneously gradually changes from the short dimension to the long dimension. In contrast, a twisted waveguide will have a rotating X-Y axis. The embodiment of FIGS. 7A and 7B produces a structure that is easier to mold than the twisted waveguide. It should be noted that, if the cross sectional area of A-A′ is the same as the cross sectional area of B-B′, the cross sectional area of the third subsection 264 should remain constant during its transition. Alternatively, if the overall waveguide comprises a changing cross sectional area according to a predetermined law related to position along the waveguide, that law should be maintained in the third subsection 264 during its transition from the first aspect ratio to the second aspect ratio.
In one embodiment, the waveguide 250 is fabricated from multiple parts. For example, the waveguide 250 can be fabricated from a first part 280 and a second part 282. The parts 280, 282 can be molded through known manufacturing techniques. For example, the parts 280, 282 can be rigid formed by an injection molding process using a synthetic resin, such as LUSTRAN� 448 (Bayer Corporation, Elkhart, Ind.). The first part 280 corresponds to a main body of the waveguide 250 and the second part 282 corresponds to a cover section. Part 280 can be molded using simple tooling and with a single action in the molding machine. The two parts 290, 282 can be molded separately and then bonded together. Other techniques for fabricating the waveguide 250 can also be used.
FIG. 8 is a perspective view of the interior of the portable audio system 100 illustrating a waveguide 300. The waveguide 300 can be described as a split waveguide structure which includes a trunk waveguide section 302 and two branch waveguide sections 304 a, 304 b. Junction ends 306 a, 306 b of the branch waveguide sections 304 a, 304 b are coupled to the trunk waveguide section 302. The long dimension of the cross section of the open end at the top 308 of the trunk can be oriented differently than the long dimension of the cross section at the junction end 310. This change in the orientation of the long dimension allows the trunk waveguide section 302 to bend around the short dimension 312 of its cross-sectional shape at the top 308 of the trunk waveguide section 302. Additionally, the aspect ratio at the junction end 310 of the trunk waveguide section 302 can be differently from the aspect ratio at the junction end 310 of the trunk waveguide section 302.
Each of the branch waveguide sections 304 a, 304 b is wrapped around an empty cavity 314 a, 314 b. The cavities 314 a, 314 b are partially formed by two walls. A vent 316 along with cavities 314 a, 314 b forms a resonant peak reducing mechanism. Since the waveguide is wrapped around a �double wall�, a large turning radius for the branch waveguide sections 304 a, 304 b is provided. Additionally, the volume and length of the cavities 314 a, 314 b can be chosen to reduce any undesired resonant peak due to the nature of the waveguide 300.
The housing 102 include the waveguide 300 having first left and right subsections 320 a, 320 b that contain left and right acoustic drivers 322 a, 322 b. The drivers 322 a, 322 b each include a radiating surface with a first side facing free air and a second side, opposite the first, facing into the housing 102 and feeding acoustic waves into the branch waveguide sections 304 a, 304 b. Each branch waveguide section 304 a, 304 b is a folded continuous tube defining an interior passage and extending from one of the first left and right subsectionns 320 a, 320 b containing the drivers 322 a, 322 b at either end of the waveguide to a branch junction 324. The trunk waveguide section 302 extends from the branch junction 324 to a single trunk opening 326 having a flared end. Each of the folds defines subsections within each branch waveguide section 304 a, 304 b. Each subsection is bounded by baffles or panels extending from the front to the rear of the waveguide. The housing 102 can also support other components such as an integrated MP3 player, a CD player, a radio, a AM antenna, an amplifier, and/or a power supply, for example.
The first left and right subsections 320 a, 320 b, respectively, are partially formed by the outside surfaces (facing the drivers) of tapered first panels 322 a, 322 b adjacent the drivers 322 a, 322 b and extend to the second subsections 334 a, 334 b. The second subsections 334 a, 334 b are formed by the inside surfaces (facing the trunk waveguide section 302) of the tapered first panels 332 a, 332 b and an outside surface of second panels 336 a, 336 b and extend to the third subsections 338 a, 338 b. Generally, each of the panels is a curved surface extending from the front or back of the waveguide and includes a free edge. A contoured post 340 is formed at various free edges to reduce losses and turbulence of the acoustic pressure waves. The third subsections 338 a, 338 b are formed by the inside surfaces of the second panels 336 a, 336 b and the outside surface of third panels 342 a, 342 b. Left and right cavities 314 a, 314 b are formed by the inside surfaces of the third panels 342 a, 342 b and the outside surfaces of fourth panels 344 a, 344 b. The fourth subsections 346 a, 346 b are formed by the inside by the inside surfaces of the fourth panels 344 a, 344 b and the outside surface of the trunk waveguide section walls 348 a, 348 b and extend the third subsections 338 a, 338 b to connect with the trunk waveguide section 302 at the branch junction 324.
In one embodiment, the cross-sectional area of each of the branch waveguide sections 304 a, 304 b continuously decreases along a path from the first left and right subsections 320 a, 320 b to the branch junctions 324. The first and seconds subsections are relatively large and can be more tapered compared with the third and fourth subsections and the common trunk waveguide section.
In one embodiment, the total volume and cross-sectional are profiles of the left and right branch waveguide sections 304 a, 304 b are similar. However, the left and right branch waveguide sections 304 a, 304 b can be asymmetrical because of the need to accommodate the packaging of differently-sized electronic components within the housing 102.
The vent 316 can be located proximate to the branch junction 324. The vent 316 connects the left and the right cavities 314 a, 314 b to the trunk waveguide section 302. The left and right cavities 314 a, 314 b form acoustic structures that are sized and configured for reducing the magnitude of a resonance peak. The length of the left and right cavities 314 a, 314 b are chosen to exhibit a resonance behavior in the frequency range where it is desired to control the magnitude of a resonance peak in the waveguide. The left and right cavities 314 a, 314 b are designed such that the acoustic pressure due to the resonance in each cavity, that is present at the branch junction 324, destructively interferes with the acoustic pressure present within the waveguide 300, thus reducing the peak magnitude.
It should be noted that the location of the vent 316 and the cavities 314 a, 314 b are not limited to what has shown in FIG. 8. The location of the cavities can be anywhere along a general waveguide system corresponding to the pressure maximum of the target standing wave and the particular resonance peak to be attenuated. The use of such cavities for damping out a resonance peak is not limited to waveguide having common trunk and branch section configurations.
