DETAILED DESCRIPTION
(19) Referring to
(20) The deck 24 is designed to accommodate an operator and two passengers. It is contemplated that the deck 24 could be designed to accommodate only the operator or more or fewer passengers. The deck 24 is shown in isolation in
(21) The space between the hull 22 and the deck 24 forms a volume commonly referred to as the motor compartment 34 (
(22) Still referring to
(23) The deck 24 has a centrally positioned straddle-type seat 70 supported on top of a pedestal 72 formed by the deck 24. Accordingly, the seat 70 and the pedestal 72 are aligned with the longitudinal centerline 29 of the deck 24. The seat 70 accommodates three riders in a straddling position. The seat 70 has a front seat portion 74, a middle seat portion 76 and a rear seat portion 78 made as cushioned or padded units.
(24) On left and right sides of the pedestal 72, the deck 24 forms foot-wells 82 that provide support for the riders' feet. With additional reference to
(25) The personal watercraft 20 has other features and components which would be readily recognized by one of ordinary skill in the art. Further explanation and description of these components will not be provided herein.
(26) The personal watercraft 20 includes a left speaker assembly 200 and a right speaker assembly 201. The left speaker assembly 200 will first be described with reference to
(27) The speaker assemblies 200, 201 are partially disposed in recesses 98 (see
(28) The speaker assembly 200 includes a housing 204. The housing 204 is made up of an inner panel 206 and an outer panel 208 snapped and fastened together. It is contemplated that the panels 206, 208 could be connected in various ways, including but not limited to: fastened, glued, and welded. It is also contemplated that the housing 204 could be made up of more or fewer panels.
(29) As can be seen from
(30) The speaker assembly 200, as can be seen in an exploded view of the assembly 200 in
(31) The speaker driver 220 is connected to the housing 204 and disposed partially in an interior of the housing 204. The speaker driver 220 includes a basket 230, which acts as a frame supporting different components of the speaker driver 220. The basket 230 connects the speaker driver 220 to the outer panel 208 of the housing 204. The outer panel 208 defines an aperture 280 on its top side for receiving the speaker driver 220 therein, and a top portion of the basket 230 sits on a lip 282 formed around the aperture 280 (see
(32) The speaker driver 220 also includes a protective cover 238 connected around a top edge of the basket 230. The cover 238 is composed of hardened plastic, but many different weather resistant rigid materials may be employed. It is also contemplated that the speaker driver 220 could be provided without the protective cover 238 in some implementations.
(33) A tweeter assembly 260 is included with the speaker driver 220 to provide enriched high frequency sounds according to known technologies. The tweeter assembly 260 includes a tweeter bridge 262 connected to the basket 230. The tweeter bridge 262 supports a tweeter driver 264. It is contemplated that the speaker driver 220 could be provided without the tweeter assembly 260 in some implementations. It is contemplated that the tweeter assembly 260 could be realized in a variety of implementations, although tweeter the assembly 260 should be water impermeable for implementations where the tweeter bridge 262 extends over a top surface of the speaker driver 220.
(34) The speaker driver 220 includes a cone 224 moveably supported in the basket 230. The cone 224 is made of plastic, but it is contemplated that the cone 224 could be made of any stiff material that is resistant to water damage. It is also contemplated that the cone 224 could be made of any number of materials, alone or in combination, and/or protected with a thin water impermeable covering, such as lamination. In some implementations, the cone 224 could be made of a water resistant material that allows water to permeate the cone 224, depending on other specifics of the design of the speaker driver 220.
(35) The speaker driver 220 further includes a flexible membrane 228, also referred to as a surround 228. The surround 228 flexibly connects the cone 224 to the basket 230. As can be seen in
(36) The water resistant speaker driver 220 also includes a water resistant voice coil assembly 242 (see
(37) The speaker driver 220 also includes a water impermeable cap 226, also referred to as a water impermeable dust cap 226, disposed in the cone 224. As can be seen in
(38) The speaker driver 220 includes a water impermeable suspension element 240, also referred to as a spider 240, operatively connected between the cone 224 and the basket 230. The spider 240 acts as an additional flexible membrane for flexibly supporting the cone 224 and the voice coil 246. The spider 240 is made of laminated polycotton and rubber, and is thus impermeable to water. The spider 240 could be made of different water impermeable and flexible materials, depending on the implementation. In some implementations, the spider 240 could be permeable to air while being impermeable to water. The spider 240 defines, along with a lower portion of the basket 230 and the water impermeable cap 226, a water impermeable chamber 234. The lower portion of the basket 230 is closed below the apertures 232 and the spider 240 is connected to the basket 230 just below the apertures 232 (see
(39) The voice coil assembly 242 is disposed within the water impermeable chamber 234 and is therefore water resistant. The voice coil assembly 242 is protected from water that enters the housing 204 of the speaker assembly 200 for reasons which are detailed below. The housing 204 is therefore not required to be a dry environment. It should be noted that portions of the magnet assembly 244 may not be sensitive to water damage, and it is contemplated that all or a portion of the magnet assembly 244 could be disposed outside the basket 230 or outside the water impermeable chamber 234. In different implementations of the water resistant speaker driver 220, other solutions for protecting the voice coil 246 and/or the voice coil assembly 242 could be implemented. In one non-limiting example, it is contemplated that the voice coil assembly 242 could be appropriately coated with a water impermeable material, and as such would not need to be disposed in the water impermeable chamber 234.
(40) The housing 204 of the speaker assembly 200 defines an aperture 215 passing through the panels 206, 208, specifically a bass port 215. The bass port 215 is defined by a pipe 218. The pipe 218 is formed in part by each of the panels 206, 208. It is contemplated that the pipe 218 could be formed in only one of the panels 206, 208. The pipe 218 serves in part to allow water to drain out of the housing 204. It is contemplated that in some implementations, the drainage hole 212 could be omitted and the pipe 218 could serve to allow drainage of water out of the housing 204. Further specific details relating to the function of the bass port 215 and the pipe 218 are described below.
(41) The speaker assembly 200 also includes a control unit 250 electronically connected to the speaker driver 220. The control unit 250 provides buttons 252 on a top portion of the unit 250 to receive commands from the operator to control the speaker driver 220 (as well as the speaker driver 220 of the right speaker assembly 201, as will be described below). The top portion of the control unit 250 is disposed on a top, operator-facing side of the housing 204 in an aperture 284 (
(42) The control unit 250 includes a wireless receiver 254 (shown schematically in
(43) The speaker assembly 200 also includes an amplifier 270 disposed within the housing 204. The amplifier 270 is electronically and electrically connected to the control unit 250 and the speaker driver 220. The amplifier 270 drives the speaker driver 220 based on signals received from the control unit 250. The amplifier 270 could be implemented in any number of ways known in the art, and no further details need be provided here. It is contemplated that the control unit 250 and the amplifier 270 could be replaced with an amplifier with wireless receiver capabilities in some implementations. As with the control unit 250, the amplifier 270 should be sufficiently water resistant to protect its electronics from the possibility of water damage.
(44) The control unit 250 and the amplifier 270 are electrically connected to and powered by the battery 92 disposed between the deck 24 and the hull 22 by the cord 292. The cord 292 extends from the amplifier 270, the amplifier 270 being is in turn connected to the control unit 250, as illustrated in
(45) The speaker assembly 201, illustrated in
(46) The speaker assembly 201 includes a housing 205, made of an inner panel 207 and an outer panel 209 connected together. The inner panel 207 is a mirror image of the inner panel 206 of the assembly 200. The outer panel 209 is nearly a mirror image of the outer panel 208, although the outer panel 209 does not have a hole through which the control unit 250 is inserted (see
(47) The speaker assembly 201 includes its own speaker driver 220, which is identical to the speaker driver 220 of the speaker assembly 200. It is contemplated that the speaker drivers 220 in the two speaker assemblies 200, 201 could be different in some implementations. The speaker assembly 201 does not, however, include the control unit 250 or the amplifier 270 of the speaker assembly 200. The speaker driver 220 of the speaker assembly 201 is powered and controlled by the control unit 250 and the amplifier 270 of the speaker assembly 200, as mentioned above. The speaker driver 220 of the right speaker assembly 201 is electrically and electronically connected to the control unit 250 and the amplifier 270 via the cord 292. It is contemplated that the speaker assembly 201 could be provided with some additional controls specific to the speaker assembly 201, such as volume controls, etc. It is contemplated that the speaker assembly 201 could include its own control unit 250 and amplifier 270 which wirelessly connects to the user device separately from the left speaker assembly 200. It is also contemplated that the speaker assembly 201 could include the amplifier 270 that connects by the cord 292 or wirelessly to the control unit 250 of the speaker assembly 200.
(48) Operational details of the speaker drivers 220 of the speaker assemblies 200, 201 will now be described, with reference mainly to the speaker driver 220 of the speaker assembly 200. The details apply mutatis mutandis to the speaker assembly 201.
(49) As mentioned above, the basket 230 defines a plurality of apertures 232. As can be seen from
(50) As is known in the art, the bass port 215 is one or more apertures that enable the sound from a rear side, i.e. the surface 225, of the cone 224 to be better transmitted of out of the housing 204, especially bass frequencies. The specific design of the bass port 215 and the pipe 218 depends on many factors, including but not limited to: volume of the housing 204, the frequencies to be transmitted, and different operational parameters of the speaker driver 220.
(51) In the present implementation, the pipe 218 is formed partially on a foot-well side of the speaker assembly 200, which is the surface of the housing 204 nearest the foot-well 82. The pipe 218 extends out of the housing 204, as well as into an interior of the housing 204. The pipe 218 forms an elbow shape as can be seen in
(52) By allowing the bass port 215 to be open facing the foot-well 82, sound quality can be improved, as discussed above. While water is likely to splash into the foot-wells 82 of the watercraft 20 at some point during operation of the watercraft 20 and thus also into the speaker assembly 200 through at least the bass port 215, the voice coil assembly 242 is sealed in the water impermeable chamber 234 and will be generally unaffected. Inclusion of the water impermeable spider 240 further allows the surround 228 and the cone 224 to be permeable in some manner, as water entering from the cone side of the housing 204 will not damage the electric and electronic components within.
(53) The speaker drivers 220 of the left and right speaker assemblies 200, 201 are also oriented to aid in improving sound for the operator. As can be seen from
(54) Specifically, the centerline 202 of the cone 224 of the speaker driver 220 of the left speaker assembly 200 extends upward, rearward, and rightward from the left speaker assembly 200 such that sound emanating from the left speaker driver 220 is directed at least partially upward, rearward, and rightward from the left speaker assembly 200. Similarly, the centerline 203 of the cone 224 of the speaker driver 220 of the right speaker assembly 201 extends upward, rearward, and leftward from the right speaker assembly 201 such that sound emanating from the right speaker driver 220 is directed at least partially upward, rearward, and leftward from the right speaker assembly 201.
(55) Modifications and improvements to the above-described implementations of the present technology may become apparent to those skilled in the art. The foregoing description is intended to be exemplary rather than limiting. The scope of the present technology is therefore intended to be limited solely by the scope of the appended claims.
